Volume 76 Number 1 1989 Annals of the Missouri Botanical Garden NA TESSMANNIANTHUS, AN ARBORESCENT GENUS OF MELASTOMATACEAE NEW TO PANAMA! Frank Almeda? ABSTRACT Recent agr o. activity in montane cloud forests of western and central Panama has led to the discovery of two new species o eru. TE im du carinatus and T. g trees previously recorded from Colombia, ordonii are described, illustrated, compared, and contrasted with similar vided. smannianthus, a little-known genus of cuador, and species. À key to the new taxa and a md history of the genus are also prov In a paper describing new Peruvian flowering plants collected by the late Günther Tessmann, Markgraf (1927) proposed the new genus and species Tessmannianthus heterostemon, to accom- modate one of the tallest known trees (30-45 m) among neotropical Melastomataceae. Markgraf's circumscription of Tessmannianthus emphasized its unique androecial characters. The connectives on the larger set of dimorphic stamens are modified dorsally into biauriculate, ventrally upturned ap- pendages. The smaller anther sacs are longitudi- nally bifurcate distally and have connectives that are prolonged dorsally at the base into bilobed or deflexed, bifid appendages. These characters, to- gether with the pentamerous flowers, trilocular cap- sular fruits, and prevailingly lepidote indument, define Tessmannianthus as a natural alliance wor- thy of generic rank. For nearly fifty years Tessmannianthus was thought to be a monotypic genus. Wurdack (1975) described T. cenepensis and transferred the enig- matic Miconia calcarata Gleason to Tessman- nianthus, enlarging the genus to three species and extending its range from Peru northward to Co- lombia. Because of its arborescent habit, rainy season flowering, and evidently limited number of individ- uals in any one population, Tessmannianthus has ' I thank John J.

ANN. Missouni Bor. Garb. 76: 1-6. 1989. Annals of the Missouri Botanical Garden escaped the attention of most collectors. Each of the species is known from fewer than six collections, and open flowers of T. cenepensis and mature seeds of T. heterostemon remain unknown. The discriminating collecting efforts of Gordon McPherson in Panama have yielded the first col- lections of the two new species described here. mong the six merianioid genera of Melastoma- taceae now known from Panama (Gleason, 1958; D'Arcy, 1987), Tessmannianthus is likely to be confused only with Graffenrieda. The latter is dis- tinguished by a calyptriform or irregularly ruptur- ing calyx, dorsally arcuate stamens, and anther connectives modified into acute dorso-basal spurs. The Panamanian species of Tessmannianthus do not appear to be closely related to one another. They are, nevertheless, readily separated from all other Central American melastomes by the follow- ing characters: the small (4-7.5 x 2-6 mm) clawed petals are retrorsely erose-ciliolate; the larger ven- trally arcuate anthers open by a pair of ventrally inclined confluent pores; and each of the bifurcate anther sacs in the smaller stamens opens by a dorsally inclined pore.

Known only from the summit area of Cerro Jefe in central Panama at about 850 m, where the new species is evidently an uncom- mon member of the low cloud forest vegetation. It grows with but appears to be greatly outnumbered by the vegetatively similar Cerro Jefe race of Cono- stegia montana (Sw.) D. Don ex DC. Tessmannianthus carinatus differs from other members of the genus in characters of the foliage, indument, and calyx lobes. The leaves of this species are leathery and sulcate, with a rounded terminal acumen that is turned downward. The indument on young branches, inflorescences, and the ele- vated primary nerves on lower leaf surfaces con- sists of a mixture of appressed lepidote hairs and spreading dendritic or pinoid hairs. The former hair type is found in all other members of the genus; the latter is unique to 7. carinatus. The specific epithet draws attention to the distinctive calyx mor- phology. Each lobe is beset with a carinate abaxial keel that forms an apically incurved clawlike tooth (Fig. 1D). Tessmannianthus carinatus appears to be with- out close relatives. Its leathery leaves are vaguely reminiscent o . heterostemon, which differs markedly in having larger (9-20.5 x 6.4-13.5 cm) apically rounded obovate blades, shorter hy- panthia (3-4 mm) with minute caducous exterior calyx teeth, and elliptic-oblong, papillate petals.

In the size, shape, and indument of its leaves, T. gordonii most closely resembles 7. cenepensis. The latter differs in the following characters: anther sacs of the larger stamens are linear-oblong and conspicuously retuse or bifurcate distally for about 0.5 mm; anther sacs of the smaller stamens are bifurcate for the distal two-thirds of their length and have connectives that are obscurely lobed but not prolonged into biauriculate appendages; the ovary is puberulent; the petals are copiously fur- furaceous-lepidote abaxially; and the hypanthia are markedly constricted below the torus into a tubular neck that shortens to a tight constriction on fruiting hypanthia. Tessmannianthus cenepensis also ap- pears to differ in other modal tendencies. Its inflo- rescences are longer (5-8 cm) and more floriferous than those of T. gordonii, and its petals are broadly ovate and appear to lack a well-developed basal claw. The consistency of these latter differences will become apparent only when better flowering material is available for study. This species is named for Gordon McPherson (1947- ),collector of the type and all other known Panamanian specimens of this genus. His many fine collections of trees, shrubs, and epiphytes have added a number of new and interesting species to the flora of Panama. LITERATURE CITED D’Arcy, W. G. 1987.

From Borneo 28 species are recognized.

Nomenclature, descriptions, illustrations, maps, and a key for all species are provided. Argostemma Wall. in Roxb. is a large, complex genus with about 220 described species. The re- vision of the genus will be published in parts dealing with different geographical areas. About 51 taxa have been described from Borneo. There is no treatment covering the whole island. In this study I have recognized 28 species, of which six are new. Most of the 28 species are endemic to Borneo, Ithough six of them were described from speci- mens collected outside of Borneo. The remaining 22 are typified on Borneo specimens. Only synonyms typified by specimens from Bor- neo are listed under the species During the 1950s, the late Dr. Bakhuizen van den Brink, Jr. studied the genus for the Flora Malesiana project. He annotated many herbarium labels about typifications. I have studied his lec- totypifications, and in most cases I do agree with him, and have accepted the lectotypifications which are published in this paper. No infraspecific taxa are recognized in this study. Most species are stenomorphous, and a few species are polymorphous. Among the latter, Æ. elato- stemma occurs as two differing populations on Bor- neo, but since its whole variation outside Borneo is not yet known, they are not recognized as sep- arate taxa. The substantial variation in Æ. borra- gineum is not correlated with geographical distri- bution and does not reveal distinct evolutionary lines. Argostemma hameliifolium and A. moul. tonii form a complex without discrete infraspecific units. The distinction between the two species is more or less preliminary. Argostemma densifolium is dimorphic, but as the variation seems small, I have treated the two morphs as one taxon. MATERIALS AND METHODS All cited specimens including types have been studied, unless otherwise stated. I have seen ma- terial from the following herbaria: A, AAU, B, BM, : >E, G; , HBG, K, KLU, L, MO, NY, P, S, SAR, SING, U, UC, and US. I have studied Argostemma parvifolium, A.

For endothecial structure, whole anthers of all species were mounted in Hoyer's solution for study. The species are arranged roughly in phyloge- netic order. Species 1-12 (the 4. parvifolium group) belong to one evolutionary group, species 13-26 (the A. psychotrioides group) to a second group, species 28 (4. neurocalyx) to a third group, and species 27 (4. bryophilum) assumes an un- certain position within the genus. The drawings are my own. In the figures (4— 31), all details of plants indicated by the same letter (B-T) are drawn at the same magnification and illustrate the same plant part. Hence, if a particular part is not illustrated, the corresponding letter is not used in the figure. The branch, indi- cated by letter A, is drawn twice as large in Figures 7-15, 17, 19-22, 30, and 31 as in Figures 4-6, 16, 18, and 23-29. SYSTEMATIC POSITION AND INTERRELATIONSHIPS WITHIN ARGOSTEMMA Argostemma is the largest genus of the Argo- stemmateae (Verdcourt, 1958; B. Bremer, 1987; Argostemmatideae fide Darwin, 1975, sphalm., pers. comm.). The other genus of the tribe is Neu- rocalyx (B. Bremer, 1979), a small genus endemic to Sri Lanka and southern India. The sister group to the Argostemmateae is the mainly Central Amer- ican tribe Hamelieae (B. Bremer, 1987). These two tribes form a monophyletic group within the subfamily Rubioideae. In Borneo there are 28 species of Argostemma. About two-thirds of these are endemic. The Bor- nean species belong to at least th t mono- AN groups, each having its sister group outside Borne The A parvifolium group is represented by species 1-12, characterized by “radial” endothe- cium (see morphological notes), leaves, rotate corollas, a narrowly ovoidal anther cone, thin and smooth apical appendages, and a glabrous style with a hardly widened to slightly capitate stigma. Three species from this group (4. parvifolium, A. elatostemma, and A. ophirense) also occur in the Malay Peninsula and on other Sunda Islands. e A. psychotrioides group, species 13-26, is ad by a sturdy connective, umbelli- form inflorescences, in most species a corolla cleft to less than half its length, and usually a style much anisophyllous longer than the stamens. Most species also have a "polarized" endothecium (one species cannot be classified as "radial" or "polarized"), and most species have an endothecium with distinct cell mar- gins (see morphological notes). Argostemma ha- meliifolium, A. moultonii, A. psychotrioides, and A. borragineum also occur on other Sunda Islands but not in the Malay Peninsula. The remaining species, 4. bryophilum (27) and A. neurocalyx (28), are more isolated. Argostem- ma neurocalyx belongs to a totally different group within Argostemma. It is characterized by an apical leaf rosette and free stamens, of which the anthers open by pores instead of slits. The group to which it belongs has a very wide distribution from West Africa to the Philippines. The systematic position of A. bryophilum is not yet clear. It does not fit in any of the groups mentioned above and is part of a complex of taxa common in the Philippines and New Guinea. MORPHOLOGICAL NOTES Raphides. Raphides are found in most parts of the plants and can be seen easily in corollas or in young glabrous stems. Colleters. On living material the colleters can be seen easily, but on old dry specimens they are hardly visible. They are of the standard rubiaceous type (Lersten, 1975), with elongated axial cells surrounded by a palisade epidermal layer. The colleters are found singly or a few together between the calyx lobes. At each node they surround the stem in a ring and occur on the adaxial side of the petiole and at stipule bases. In species with few colleters in each ring, the colleters are generally round in outline, whereas in species with a dense ring of several hundred colleters they are narrow, often reduced, and almost without a palisade epi- dermis (Lersten, 1974). The stipules often end in apical colleters. In Argostemma chaii, with fringed stipules, each of the processes making up the fringe ends in a distinct colleter. Hairs. In Borneo, only A. apiculatum is gla- brous. The other species are more or less entirely or partially pubescent. There are no substantial differences between hairs on vegetative organs and those on flowers. Normal hairs are monoseriate and completely septate, with thin to very thick walls, and they generally do not collapse when dry. They may occur all over the leaf surfaces or only on (or rarely only between) the veins. If there is indu- mentum on the inside of the corolla or on the style, the hairs are shorter, mostly one- or few-celled and thinner (Verdcourt, 1958). Another hair type oc- curs on, e.g., 4. rupestre (Fig. 131) and A. gee- Volume 76, Number 1 1989 Bremer 9 Argostemma in Borneo sinkii (Fig. 141). On the upper leaf surfaces of these species there are three or five rows of stiff, pluricellular hairs. One row occurs along the midrib and the others along the margins, making them appear more or less serrulate. Leaf anatomy. | have studied in detail cross sections of field-fixed material of 4. bryophilum, A. elatostemma, A. havilandii, A. moultonii, A. ophirense, A. psychotrioides, and A. rupestre. Cross sections of young leaves of the species are generally very similar. With the exception of A. bryophilum, cross sections of these species can be described as follows: upper epidermis of one layer of large, rectangular cells with rather thin walls and lacking plastids; palisade chlorenchyma of one or a few layers of small carrot-shaped cells filled with plastids; spongy parenchyma of a few to many layers of small to medium-sized cells almost without plastids; lower epidermis of one layer of large, rounded cells with thin walls and without plastids; stomata quite exposed. This type of leaf also occurs in Neurocalyx (B. Bremer, unpubl.). Argostemma bryophilum, aberrant in many other ways, differs from the others in leaf cross section. Its epidermal layers are thinner with smaller cells, and the chlor- enchyma consists of large rounded cells with few plastids. Species whose lower leaf surface appears white (e.g., A. rupestre and A. gracile) have more in- tercellular spaces in the spongy parenchyma than other species. Endothecium. The endothecium of Argo- stemma (Fig. 1) was studied with light microscope on whole mounts of anthers. The endothecium var- ies between groups of Argostemma species. In A. bryophilum and A. neurocalyx, in many ways aberrant species, only narrow longitudinal bands of cells close to the stomium have wall thickenings, while in all other species from Borneo, wall thick- enings occur in all cells of the endothecial layer. In the following, the terms endothecium, endothe- cial layer, and endothecial type will only be used for those cells with wall thickenings. The endothecial cells are generally elongated longitudinally or horizontally compared with the line of dehiscence and with the anther-length axis, or rarely they are isodiametric. In Argostemma the wall thickenings are U-shaped ribs arranged transversely in relation to the longest axis of the cell and with their openings toward the epidermal layer. The ribs end in knobs. Dormer (1962), Nordenstam (1978), Noel (1983), and French (1985) have shown the sys- tematic significance of endothecial structures. This study shows that different endothecium types occur in Argostemma and that these types are restricted to different systematic units within the genus. Dor- mer (1962) and Noel (1983) presented systems for classification of endothecial structures. Dormer (1962) classified endothecial cells in the Compos- itae as “polarized” or “radial.” In a polarized en- dothecium the thickenings are concentrated mainly at the upper and lower ends of the cells, and when ribs occur they are parallel to the line of dehiscence. In a radial endothecium the cells are ribbed all around; on elongated cells the bars are arranged transversely, parallel to the line of dehiscence. I have found Dormer's system somewhat difficult to use with Rubiaceae because the endothecial cells are different, often elongated horizontally, i.e., transversely to the anther-length axis. In Compos- itae (Nordenstam, 1978; Dormer, 1962; K. Bre- mer, pers. comm.), when the cells are elongated, the elongation is parallel to the anther-length axis. Noel (1983) presented a more general system which embraces over 500 taxa from different fam- ilies. He distinguished several endothecial char- acters, such as size and shape of the cells, orga- nization of the thickenings, whether a basal plate and/or ribs occur, and the shape and number of these. In general, the endothecial cells of Argo- stemma can be characterized following Noel’s scheme (1983: 837): cells medium-sized, 27-60 um on the longest side, isodiametric, rectangular or fusiform; wall thickenings localized; base plate absent; ribs U-shaped; 5-ca. 15 ribs per cell (in several species the cell margins become indistinct, and it is difficult to see where the cell ends); spacing from close to wide; branching absent; tips knobbed. gostemma. The first two are e first type, in A. bryophilum, A. hameliifolium Fig. 1A), 4. moultonii, and A. neurocalyx, the cell margins become indistinct, and the endothecial layer can be described as consisting of long, hor- izontal, rather narrow bands with many close dis- tinct transverse ribs and knobs. This type also occurs in the sister genus Neurocalyx. 1 have ex- amined the endothecia of Hamelia patens, Hoff- — mannia vesciculifera, and Xerococcus congestus, belonging to Hameliieae, the sister tribe to Argo- stemmateae (B. Bremer, 1987), and they are of the same type. In the second type (e.g., A. enerve, A. gracile, A. havilandii, and A. psychotrioides (Fig. 1B)), the cells are horizontally elongated and fusiform but with distinct cell margins. The ribs are not as close together, and the knobs are larger than in the first type. Annals of the Missouri Botanical Garden Oo : AU Eps JRE l. Endothecial cell thickenings. Scale a = rgostemma hameliifolium. —B. A. a —C. A. parvifolium. —D. A. alae ic The third type could be classified as "radial." This type occurs in many species, e.g., Á. ophi- rense, A. parvifolium (Fig. 1C), and A. rupestre. The cells are generally rectangular, with the lon- gitudinal axis parallel to the dehiscence line. The cells are larger than in the ““polarized” group. The transverse ribs are indistinct to hardly visible, and the knobs are smaller and look like a string of pearls surrounding the cell margins. fourth group consists solely of 4. borra- gineum (Fig. 1 D), whose endothecium is unique at least among the Borneo species of Argostemma. The cells are generally isodiametric and large. The ribs are indistinct, generally arranged parallel to the dehiscence line, and the knobs are indistinct. Since the ribs are not transversely arranged in relation to the anther-length axis, this type cannot be described as **radial," and since the knobs sur- round the cells on ie margins, it cannot be de- scribed as “polarize Fruit. cles become erect. These parts and the fruit, After anthesis the pedicels and pedun- crowned with the calyx lobes, become fleshy and succulent. The fruit opens by an apical operculum. Such fleshy capsules are not uncommon in the tropics (Ehrendorfer, 1983: 829). Bakhuizen f. (1975) said about fruits of Rubiaceae: I am convinced that true capsules are not found in distinctly t eshy known as * ‘drupe’ ”) and vise (having a (very) thin, dry, ks leathery pe ricarp, so- iait capsule’ -pyrenife rous are conventionally lema “berry.” 46 The fruit of Argostemma does not fit into this system. Although Bakhuizen f. was an expert on this genus, he had never seen it in the field (pers. comm.), and on dry material he had probably mis- interpreted the fruit type. When the fruit is open the fibrous endocarp separates from the remaining pericarp and splits into threads, which are visible in the opening. The septum, with the attached placentas, is also fibrous and will split. Among the resulting threads the umerous seeds will be exposed. Perhaps the threads Mii sudden dispersal. It is not uncommon to find specimens with many seeds germinated within the capsules. This kind of “vivipary” or germi- nation in situ is described earlier from Ophiorrhiza tomentosa (Tan & Rao, 1981). Placentation. Placentation is axile with the placentas (Fig. 2) attached at the top of the septum. he placentas are stalked, pendulous, fleshy, and in front view broadly ovoidal to kidney-shaped. Seeds. | Argostemma has numerous, small (ca. 0.5 mm), angular to ovoidal seeds (Fig. 3). The testa seems to be unique to this genus. The surface is mostly reticulate with a mamilla or a ring in each cell. DISTRIBUTION The maps (1-28) of Argostemma show that most localities are from northwestern Borneo. This is not because Argostemma is more common there, but indicates that this part, Sarawak, is botanically most well known. The same pattern can be seen in Memecylon (K. Bremer, 1983) and other gen- era. The few localities in Kalimantan result from comparatively few botanical expeditions, and large areas of former rainforest have been deforested. Taxonomically, Argostemma in Borneo belongs to at least three different species groups which are more or less sympatric, and many species within the same group are sympatric. The distributions of different species of Argostemma are influenced by altitude, a fact that is hardly evident on the maps. Argostemma elatostemma, A. densifolium, A. havilandii, A. cal- cicolum, A. trichosanthes, A. psychotrioides, and A. variegatum grow only at low altitude; and 4. A. gaharuense, A. chaii, anisophyllum, A. dulitense, A. apiculatum, A. burttii, A. geesinkii, A. gracile, A. brachyanthe- rum, and A. brookei grow only at altitudes over 1,000 m. Some species occur at both low and high altitudes: 4. parvifolium, A. subfalcifolium, A. ophirense, A. A. hameliifolium, A. moultonii, and A. borragineum. Most of the lowland species and those growing rupestre, Volume 76, Number 1 Bremer 11 Argostemma in Borneo Is fv FIGURE 2.

Of the eight species known only from a single locality each, four are from high altitude, the altitudes of three are unknown, and only one is from low altitude (ca. 70 TAXONOMIC TREATMENT Argostemma Wall. in Roxb., Flora Indica 2 324, 1824.

There is a question mark after Java on the label of the type specimen, and on the label there is also written “Sumatra,” as is indicated in the proto- logue. Argostemma parvifolium grows on sand- stone, sandy banks, and cliffs near streams, from 350 to 1,450 m. The species is based on non- Borneo material. The habit of the Borneo popu- lation is similar to the type of A. parvifolium var. involucratum (Hemsl.) Bakh. f. I have not studied the complete variation of A. parvifolium outside Borneo, and so for now I avoid infraspecific taxa. Except for the inner floral parts, the whole plant is densely covered by long soft hairs. As in all Argostemma species, the flowers are slightly pen- dulous at anthesis, and in this species the flowers are slightly zygomorphic. The rotate corolla has at its center distinct green nectar guides on the upper half. The anther cone is bent upwards and the stamens, in the upper half of the flower, have curved filaments. It is the only Borneo species with these characters. Annals of the Missouri Botanical Garden D 0.2mm G i .05cm CD ; ._ 1cm B; 2cmEF , |, 20cm A FIGURE 4. Argostemma parvifolium. —A. Branch.— B.

(in herb.) selected the Griffith specimen in K, and I follow his choice. Argostemma elatostemma grows in wet shady forests, from 100 to 750 m. It occurs in the first division of Sarawak and on the southern tip of Kalimantan. The collections from these two areas are different. The Sarawak specimens are alike and similar to the type collection from the Malay Pen- insula, while the Kalimantan specimen, described as A. motleyi, agrees well with the type of A. elatostemma var. obovata King (1904). In this study I have not dealt with any infraspecific taxa because I have not yet studied the complete vari- ation outside Borneo. The specimen from Kali- mantan is smaller with shorter leaves, and there is only one flower in the collection. Argostemma ela- tostemma is characterized by its creeping habit, rooting at the nodes, silvery mottled leaves, and unequal leaf bases. The stems, petioles, veins of the lower leaf surfaces, and the inflorescences are densely pubescent. The flowers are rotate with a long pale anther cone which blackens in the press.

The species is characterized by rather long calyx lobes and by furrowed fruits. The stems are glabrate and sometimes slightly pubescent. The peduncles and lateral branches of the inflorescence are mostly glabrous, whereas the pedicels, ovary, and lower part of the calyx lobes are pubescent. The flowers are rotate, and the buds are distinctly angular in cross section. The staminal cone is high. From the outside the thecae are completely shed by the connectives but can be seen as immerse sacs between the filaments. here are a few aberrant specimens. Anderson 4090, from Bako in Sarawak, consists of very small plants. They were collected on fallen tree trunks and have a peculiar habit, but no other details contradict inclusion in this species. Meijer 2286, from Kalimantan, has nearly cordiform nanophyl- lous leaves, but otherwise fits. Brooke 9194, from Sarawak, has very narrow leaves with obscure pri- mary veins.

There are only a few collections of this species, and they are in bad condition. The description of the flowers was prepared from undissected flowers, and so some information is lacking. The scanty information on its habitat indicates that it grows on steep sandstone slopes and on gentle slopes on litter. It was collected at low altitude in south- western and northeastern parts of Sarawak and in Sabah. I have not managed to find the locality "Bongaya," but according to Steenis-Kruseman (1950), Ridley visited the Kudat, Sandakan, and Lubak Bay in 1897, so it must be somewhere in this area. Ridley (1927) described two varieties of this species. I agree with him that the two popu- lations are different. The southwestern population (Fig. 7A), including the type of 4. densifolium, has narrow leaves and glabrous inflorescences, while the northeastern population, including the type of var. latifolium, has denser foliage with larger, broader leaves and pubescent inflorescences. In this study, however, I have chosen not to deal with infraspecific taxa. On herbarium labels, Bakhuizen f. has treated these taxa as synonyms of A. ophi- rense. Argostemma ophirense and its allies are complex, but A. ophirense and A. densifolium from Borneo are two distinct taxa, in my opinion. Argostemma densifolium has a different leaf shape, denser foliage, and long peduncles. Additional specimens examined. BORNEO.

The SING specimen must be treated as the holotype and the K specimen as an isotype, as Ridley (1912) said that the specimens are preserved in SI Argostemma ophirense grows on ground or on rocks in forest from 50 to 1,300 m; most collec- tions are from under 1,000 m.

Style ca. 4.5 mm long, glabrous, with a scarcely widened stigma, shortly exserted. Fruit with 5 distinct ribs corresponding to the mid- dle vascular strands of the calyx lobes. Argostemma gaharuense was collected by Burtt at 660 m at Bukit Gaharu. Its habit is not given on the herbarium label. On the label of the type specimen is written: "Leaves dark green above, white below. Corolla white, lobes strongly reflexed. Base of anther cone green, tips white." It is a small, easily recognized plant. The leaves are dark and pubescent on the upper surfaces, and below they are white and gla- brous. The stems are distinctly branched distally with many apical inflorescences, each with one to six flowers in lax cymes. The vascular strand to each calyx lobe becomes a distinct rib, making the fruit five-ribbed. The habit is similar to that of A. rupestre, A. geesinkii, and A. burttii, but A. haruense differs from these by having monoseriate leaf hairs, branched stems, and reflexed corolla lobes. The leaf and stipule shapes are the same as those of A. geesinkii. The specimen from Gunong Apeng has narrower leaves than the type, and there is only one inflorescence with two flowers. However, it has reflexed corolla lobes and the same kind of indumentum. Volume 76, Number 1 1989 Bremer 27 Argostemma in Borneo FIGURE 16. Argostemma hameliifolium.— A. Flowering branch. —B.

(in herb.) selected the single Hullett specimen in SINC, and I follow his choice. The elevation mentioned in the proto- logue is indicated only on that specimen. Argostemma hameliifolium is common and is widely collected. It grows from low altitude to 2,000 m. Most collections are from sandstone; a few are from limestone. It grows on boulders or sand in wet places near streams or waterfalls. Argostemma hameliifolium is part of a big, poorly understood complex, which includes 4. moultonii (see discussion under that species).

The leaves vary in shape and size and in distinctness of nervation. In a few cases the leaves are very broad and obtuse; these are similar in appearance to A. borragineum. The stipules, of which only the upper first to third pairs are persistent, are large, ovate to ligulate, and entire or slightly cleft. The flower buds are narrowly ovate in outline. The anther cone is high with short, free apical ap- pendages and generally short filaments. The mar- gins are longer than the central part and incurved so that each apical appendage forms an open cyl- inder. The style is generally hairy with a distinct capitate and slightly bifid, slightly exserted stigma. In this treatment I maintain A. hameliifolium sep- arate from A. moultonii. There are many distin- guishing characters, though not always constant, and many specimens are impossible to determine with certainty. Argostemma hameliifolium is more erect and has larger vegetative organs. Its anthers have short apical appendages and shorter filaments. Additional specimens examined. BORNEO.

(pers. comm. and on herbarium labels) treated 4. parvulum as a synonym of 4. hameliifolium; he believed it to be a dwarf form. However, I have found that 4. parvulum is better accommodated as a synonym of 4. moultonii. Argostemma moultonii grows in wet, damp places among mosses on tree trunks, on cliffs, or on sandy or clayey soil, and a few collections are from limestone. It grows from low altitude up to ca. 2,000 m; most specimens are from ca. 1,000 m. Ridley based A. moultonii on two collections by Moulton, in K. Both are suitable for lectotypifi- cation. Bakhuizen f. (in herb.) selected one of the specimens, Moulton 6695, and I follow his choice. Ridley based A. velutinum on three collections, in K, by Haviland, Moulton, and himself. All are suitable for lectotypification. Bakhuizen f. (in herb.) selected the Haviland specimen, and I follow his choice. Argostemma moultonii and A. hameliifolium form a complex in which a number of species have been recognized (see above). This complex is well defined as a group by unique characters: equal, opposite leaves; long, glabrous peduncles; pubes- cent pedicels; corolla cleft to near the base and with narrow, spreading or reflexed lobes; and con- nate anthers with distinct apical appendages which are free in the upper part and have margins longer than the central parts and incurved to form an open cylinder. There are at least two species (4. hameliifolium and A. moultonii) involved in the complex. | cannot recognize more in spite of the fact that this group is the most widely collected in Borneo. There are a few specimens similar in habit to the highly variable species 4. aequifolium Ridley (1901) from the Malay Peninsula and Sumatra, but this species does not have the unique stamen characters. Specimens similar to the type of A. hameliifolium, erect, large plants, are referred to A. hameliifolium, but the rest could be separated into several variable groups within A. moultonii. There would be many specimens that could not be placed with certainty. Argostemma moultonii needs further eed I have dealt with it in a manner similar to Dr. huizen f. (pers. comm.). Argostemma OIM generally can be characterized and separated from A. hameliifolium by having a smaller, creeping habit, generally longer internodes, smaller stipules, and anthers with long filaments and long apical appendages. Within 4. moultonii at least six local populations with distinct morphological characters can be identified. From some localities different populations are found without continuous variation between them. Characters separating these popu- lations are indumentum of the stems, leaves, and floral parts and the shape, texture, and nervation of the leaves. The following examples illustrate this. At the summit of Mt. Matang the plants (including the type of 4. velutinum) have ovate leaves with acuminate apices, distinct primary veins, and long petioles, and the plants are covered by long hairs. Close to that locality, at Lundu and Berumput, the collections (including the type of 4. mjoebergii) are similar in habit but less pubescent and have shorter petioles and less distinct veins. At Gunong Murud several different populations occur. One is Volume 76, Number 1 1989 Bremer 31 Argostemma in Borneo D C 0.2mm G , _05cm CD , ı Icm B; 2cmE j ¿20cm A E FIGURE 18. almost glabrous (dry specimens) with very thick, veinless, elliptic, acuminate leaves and with very long internodes (Burtt & Martin 5326, Noote- boom & Chai 1935). Except for the very long internodes, they are similar to the type of A. par- vulum from Baram. Another population includes the type of A. murudense with small, broad, ovate to rounded, obtuse to acute, densely pubescent leaves. These specimens are similar to the type of A. moultonii from the upper Baram. Martin 38848 represents a different population with glabrous, ob- ovate leaves with distinct prominent veins. From Ulu Tinjar in Baram, there is a collection (Chai 34832) with glabrous linear leaves. From Mt. Kin- abalu, there are several different populations—one (Gardner 88) is glabrous with thick, veinless leaves but different from the glabrous specimens from Gunong Mulu. There are also specimens with ovate to obovate, slightly pubescent leaves. Plants from Kutei and Gunong Tapa Sia in Kalimantan (Endert 3614, 4238 and Axelius 112B) are small rosettes with ovate, obtuse leaves having very long hairs. These collections are similar to Nooteboom 921 from Gunong Alab in Sarawak. Perhaps these rep- resent something different and distinct from 4A. moultonii, but based on the scanty material avail- able, it is impossible to decide. Additional specimens examined. BORNEO.

All specimens are suitable for lectotypification. Bakhuizen f. (in herb.) selected the specimen in L and I follow his choice. Valeton did not indicate any collection in the protologue of A. streblosifolium. In the Bogor her- barium (BO) there is only one specimen (Amdjah 319) that fits the picture and the protologue. Bak- huizen f. (in herb.) has selected that specimen, and I follow his choice. Argostemma borragineum is one of the most common Argostemma species from low altitudes to ca. 2,000 m. It often grows near shady streams. All notes concerning its habitat place it on sandy, loamy soil, sandstone, or sedimentary rocks. It is highly variable. The majority of the plants are large, to 1 m high, with black and scarred stems. The opposite leaves are equal, large, and rounded, and the stipules are broad and distinctive. The inflorescences are densely pubescent and generally very large, sometimes with more than 150 flowers. They commonly develop two or three scorpioid branches, which become most prominent after an- thesis. The corollas are cleft for about half their length into recurved lobes. The stamens are unique. The entire stamen is coriaceous and (on dry spec- imens) dark, and no differences can be discerned between the connective and the thecae, at least not from the dorsal side. The apical appendages Volume 76, Number 1 Bremer 33 1989 Argostemma in Borneo eta ea A Ad T3 Sy RN 1 5 5 ^ 4 d EF g 1 6 RC rff ees 100 km Ra O ba d. 00 km ¿EE > 500 m #% > 500 m Mars 15, 16. are separated in a characteristic way. The style is generally densely pubescent and bears a distinct capitate stigma strongly exserted. There are also plants uniformly smaller in all organs except for the flower, with smooth stems and more densely pubescent inflorescences, but there are also other small plants which have scarred stems. Several different populations have been collected from Mt. Kinabalu. I have not found any correlation between the morphological variation and any pattern of distribution.

Argostemma flavescens is known from only two very poor collections. Both were examined, but there is still a great deal of information missing about the species. It has a characteristic habit, and its leaves are densely pubescent, particularly be- tween the veins. In all other Borneo species the indumentum is more dense on the veins. The in- formation on the flowers in the description is taken from Bakhuizen f. (1953, and pers. comm.). He placed A. flavescens close to A. borragineum be- cause of its stamens. In my opinion it is not possible to determine its closest relatives within Argostem- ma at this time. Additional specimen examined. BORNEO. SARAWAK: 1st Div., Mt. Matang, Beccari 621 (L). 17.

Style ca. 3-6 mm long, glabrous, with a discoid stigma, long-exserted. Fruit without furrows or ribs. This species is named after Mr. Paul Chai of the Forest Department, Sarawak. Argostemma chaii grows on dead wood, wet rocks, or wet ground in the lowland rainforest, to 300 m. This species is a very small herb, with leaves more or less condensed into rosettes. Its primary veins are ob- scure, and the stipules are broad and fringed api- cally with colleters. The flowers are characteristic, with thick corolla lobes and free anthers. The fil- aments are wide, fixed at the base of the corolla, and adnate with it for a short distance. The stigma is discoid. Volume 76, Number 1 1989 Bremer 35 Argostemma in Borneo Distributions in Borneo. — 17. Mars 17, 18. Argostemma chaii is a rare species collected from two different areas in Sarawak. The collec- tions from the 5th Division are hairy on the ped- icels, calyx, and on the outside of the corolla. The leaves also have scattered hairs. From the lst Division the plants (including the type specimen) are glabrous in all parts. From Mt. Matang in the lst Division the leaves are distinctly larger than from other localities. Bakhuizen f. (pers. comm.) has treated this taxon as a synonym of A. inaequale (Bennett, 1838). Their habits are similar, but their flowers are dif- ferent. Argostemma inaequale does not have the thick corollas nor the discoid stigma, and its anthers have long apical appendages, while the anther ap- pendages of A. chaii are very short.

Flowers 5(or 6)-merous; calyx lobes 2-3 mm long, triangular to cordiform, pubescent in lower parts; corolla ca. 8 mm long, cleft less than Y its length, externally glabrous and internally pubescent only along the margins of the lobes; lobes broadly tri- angular, spreading. Stamens ca. 2.5 mm long, free; anther cells and apical appendage free, not forming a cone; filaments ca. 14-14 as long as the anthers, equal, straight; sacs opening completely longitu- dinally; apical appendages almost absent, thick and slightly papillose; tive distinct, smooth. Style ca. 5 mm long, alabrona, with a discáid, bifid stig- ma, long-exserted. Fruit without furrows or ribs. Argostemma gracile grows on fallen rotten logs or on rocks among mosses in submontane or mon- tane forests from 1,000 to 1,600 m. One collection (Bremer 1667) is from low elevation, 350 m, in an area of lowland rainforest with big boulders covered by mosses. Argostemma gracile is easily recognized, with its creeping habit and distichous, anisophyllous leaves, the nanophyllous leaves above the larger leaves. The leaves are thick with a distinct midrib but without other visible veins. They are silvery white beneath. The petiole and midrib have a few hairs on both surfaces, but one exception is the type specimen of A. podochiloides with completely glabrous leaves. The stipules and petioles are more or less connate with the amplexicaul sheath. This character, combined with the glabrous leaves, has been used for recogniton of 4. podochiloides, a species not accepted here. Flowers in A. gracile are solitary on very short pedicels and without peduncles. The corolla is campanulate with spread- ing lobes. The stamens are free, and there are practically no apical appendages. The stigma is distinctly bifid and discoid. Additional specimens examined. BORNEO.

Argostemma brookei has been collected from the ground in the forest in the Poi (= Pueh) range at elevations of 1,000 to 2,000 m. It is medium sized with oblanceolate, aniso- phyllous leaves. The upper part of the stems, the peduncles, and the whole inflorescences are cov- ered by rather stiff hairs. The length of the calyx lobes is intermediate between the short ones, most common among the Borneo species, and the long lobes of A. psychotrioides. Most specimens of this taxon have been deter- mined as A. brachyantherum, another mountain species, which occurs mainly at Kinabalu. In habit they are similar, but Argostemma brookei has many small flowers with deeply cleft corollas having evidently recurved lobes. The free anthers are long- er and stand close together, like a cone; the apical appendages are much longer, and the filaments are shorter than in A. brachyantherum. e ional Vague examined. NEO.

All are suitable for lectotypification. Bakhuizen f. (in herb.) has selected Teysmann 11292 in L, and I follow his choice. Bakhuizen f. selected the K specimen of A. havilandii as the type (= holotype). This is a mistake because Ridley (191 2) stated that the plants are preserved in the Singapore Botanical Gardens (note under 4. ophirense). Argostemma havilandii has a scattered distri- bution. Most, if not all, collections are from lime- stone. It grows from 50 to 1,100 m elevation on litter or more or less as an epiphyte on tree trunks, usually in lowland rainforest. It is easily distinguished. The stem is black on the upper part (on dry specimens), and the lower transverse bars. The corolla is cleft to about its middle into recurved lobes. The anther cone is low and pale yellow to creamish. The connectives are distinct, and the thecae are separated from each other at anthesis. The broad, thick apical append- ages are connate along their whole length. Argostemma havilandii is easily circumscribed. There is little variation among the populations ex- cept for width and hair cover of the leaves. From around Gunong Api there is a population with a very dense hair cover, even more distinctive than the densely pubescent specimens from Sungei Bika in Kalimantan, where they have been described as A. hallieri var. sparsipilum.

Style 5-6 mm long, pubescent, with a clavate stigma, long- exserted. Fruit without furrows or ribs. This rare species has been collected only four times. Haviland and Hose made the first collection, noting only the locality as Baram. Different col- lectors recorded it as growing on limestone. An- derson said “frequent in crevices on vertical lime- stone rocks." My collection is from low altitude in a limestone area. The earlier collections were a determined as A. borragineum because of the equal, opposite leaves. However, the stems, stipules, an- thers, and style are quite different. It is close to A. havilandii and shares various characters with this species: lower stems pale brown to grayish, these having papery to corky surfaces and elevated ridges; anther shape; and clavate pubescent styles. However, Argostemma calcicolum differs from A. havilandii by its denser pubescence even on the peduncles and stipules, isophyllous leaves, and the upper part of the connectives distinctly papillose to hairy.

Argostemma humifusum has been collected twice, but nothing was recorded about its habit or habitat. This species is characterized by its broad, ob- ovate leaves and large cordiform stipules. Because of incomplete material, I do not know the shape of the corolla. It has a thin corolla similar to those generally cleft halfway into recurved lobes. Inter- nally the corolla seems to be glabrous, but among the other species with thin corollas, the lobes are usually pubescent. The upper part of the connec- tive is probably papillose to pubescent as in 4. calcicolum and A. trichosanthes. Additional specimen examined. BORNEO.

Argostemma psychotrioides is found mostly at altitudes less than 250 m, although it occurs up A m. It grows in shady, wet places on exposed roots and pneumatophores in swampy for- ests and on boulders in streams. It also grows under drier conditions on limestone and at higher altitudes in mossy forests. It is easily identified by its strongly reflexed calyx lobes which in living material are green with white margins and tips. The corolla is thin and pubescent to densely pubescent and has recurved lobes. The anther cone is low, pale yellow to creamish. Only the apical appendages are connate, and the thecae are free. The thick apical appendages and the back of the thecae are distinctly papillose to hairy, while the connectives are smooth (cf. A. trichosanthes). 26 te ¿Ef > 500 m Distributions in Borneo.— 25.

With one exception, all Volume 76, Number 1 1989 Bremer 47 Argostemma in Borneo collections have isophyllous, opposite leaves, very pubescent stems, and cordiform, glabrate stipules. The flowers are solitary, starlike and with long, bright yellow anther cones. The thecae distinguish this species from all others: the inner pollen sac of each theca is only ca. half as long as the outer one, which is almost as long as the whole anther, and there is no distinct apical appendage. The stigma is distinctly clavate with papillae covering the clavate area. In all flowering specimens (five of the seven known specimens), the stigma is totally covered by germinated pollen grains. The pollen is probably from the same because the stigma is partly covered by the apical anther parts. ower, I have not found more than a few pollen grains on the stigmas of any other species. Probably this species is autogamous. pecimens examined. BORNEO.

The pro- tologue says “a succulent erect herb in dense for- ests on moss-covered basaltic rocks over which water trickles."

On dry specimens, the leaves are very thin and membranaceous. It is difficult to determine from the herbarium specimens if there are stipules or just smaller leaves. The umbelliform inflorescences have long glabrous peduncles, rather large, ovate bracts, and pubescent pedicels. The flowers are tetramerous and campanulate, and the corolla lobes seem to be reflexed. The stamens are free with long filaments and connectives ending each pollen sac. The pores (slits) are placed between the sacs of each theca. As the dorsal sacs are larger 48 Annals of the Missouri Botanical Garden than the ventral sacs, only the pores of the dorsal ones can be seen (from the inside of the flower), and the pores of the ventral sacs are hidden by the longer dorsal sacs.

The Culebra Formation is oldest (basal) and is overlain by the Cucaracha Formation. The La Boca does not anywhere lie directly on the Cucaracha, but it interfingers (viz., is contempo- raneous) with the Pedro Miguel Formation, which overlies the Cucaracha elsewhere in the Canal re- gion. Age estimates are based primarily on mol- luscan (Woodring, 1957-1982) and ostracod (Van den Bold, 1972, 1973) data which suggest an early Miocene age for the three formations. he La Boca outcrops along both sides of the Panama Canal from the Pacific entrance to the Las Cascadas Reach. The sediments were deposited in an estuarine environment and include an alter- nating sequence of mudstones, siltstones, sand- stones, lignitic shales, tuffs (waterlain volcanic ash), — and limestones typical of that environmental set- ting. The presence of the coralliferous Emperador limestone member in the lower part of the for- mation and Rhizophora-containing lignitic shales indicate deposition in warm temperate to tropical, shallow seas and in adjacent coastal, brackish-water habitats. Fifty-four samples were collected from two ex- posures of the La Boca Formation along the Las Cascadas Reach in September 1967 (latitude 9°04'N, longitude 79?40'W; ground elevation 52.7 m). Locality A (samples 1-26) was at Canal marker 1600 (1766 in the new marking system), and lo- cality B (samples 27-54) at markers 1622 (1788), 1625 (1791), and 1627 (1793). Since that time the Canal has been widened from 90 m to 155 m, and compared with the present physiography, the 1967 samples were collected about 25 m up and 60 m out over the present Canal. The beds dipped back into the slope at a 20-25? angle so that now !

Other details of the collecting site and geology of the area are summarized in Graham et al. (1985: 495-502). MATERIALS AND METHODS Extraction and processing techniques are de- scribed in Graham (1985). Slides are labeled ac- cording to locality, sample number, and slide num- ber (e.g., Pan A 5-1). Of the 54 samples collected, 20 contained fair to well-preserved palynomorphs (locality A—5, 14, 16, 17, 19, 20, 21; locality B— 27, 28, 29, 30, 33, 34, 35, 45, 46, 47, 50, 52, 54). Location of the specimens on the slides is by England Slide Finder e (e.g., ESF C-29). The tabulations in Table 1 are based on five representative samples (14, E 20, 21, 50) containing diverse and well-preserved palyno- morphs. All materials are deposited in the paly- nology collections at Kent State University. SYSTEMATICS Thirty-nine palynomorphs have been identified from the La Boca Formation (Table 1) in addition to 15 others that cannot presently be identified (unknowns 1-15). Most of the specimens have been recovered from other Tertiary formations in the Gulf/Caribbean region and discussed in pre- vious publications, hence the material presented here is synoptic. These formations and references are as follows: Gatuncillo (middle(?) to late Eocene, Panama; Graham, 1985); San Sebastian (middle to late Oligocene, Puerto Rico; Graham & Jarzen, 1969); Uscari (early Miocene, Costa Rica; Gra- ham, 19872, b); Culebra (early Miocene, Panama; Graham, 19882), and Cucaracha (early Miocene, Panama; Graham, 1988b). Present ranges of the modern analogs within the Neotropics and ecolog- ical data are based on field observations, personal communication with specialists, and the literature, especially Croat (1978), D'Arcy (1987), Hartshorn (1983), Tryon & Tryon (1982), and Woodson & Schery (1943-1980). Terminology for vegetation types follows Holdridge (1947; Holdridge et al., 1971), used by Croat (1978) and Hartshorn (1983) for describing the plant communities of Panama and Costa Rica. In instances where the modern analogs extend into South America, their altitudinal ranges and community affiliations may differ slight- ly from their Central American occurrences. The data for Central America are considered first in paleocommunity and paleoenvironmental recon- struction of the La Boca flora, since communities in South America are more distant and were iso- lated from Central America until about 3 Ma. FUNGI Ascomycete cleistothecium (Fig. 1). Flattened, circular, multicellular, cells cubical, 6 x 9 um, outer and some lateral walls of peripheral (mar- ginal) cells thickened, center opaque (solid?), cells disrupted along outer edge, forming slitlike opening 35 um long (attachment scar?); 124 Reproductive structures of the Plectomycetes group of ascomycete fungi are frequent in Gulf/ Caribbean Tertiary deposits but never in large num- bers. Although entire specimens are relatively rare, fragments are present in almost all samples. Another type with radially aligned cells and marginal spines was recovered from the lower Miocene Uscari se- quence of Costa Rica (Graham, 1987a, fig. 1). PYRROPHYTA Spiniferites (Figs. 2, 3). These dinoflagellate cysts, as fossils referable to Spiniferites, are com- mon in the Tertiary and extend back to the Early Cretaceous. They are produced by some species of the extant Gonyaulax group (Evitt, pers. comm., 87) This is also a common Tertiary form produced by the modern Gonyaulax grindleyi (= Protoceratium Operculodinium centrocarpus (Fig. 4). reticulatum) and a frequent associate of Spinifer- ites in the Miocene. According to Evitt (pers. comm., 1987), “These two cyst types are common con- stituents of Tertiary nearshore sediments. They occur, virtually to the exclusion of other forms, in the Miocene Monterrey Formation in California (Spiniferites much the more abundant), and to- gether with a very rich associated assemblage in the Calvert Formation along the east coast. It would be entirely plausible to find them in estuarine de- posits of Miocene age virtually anywhere. No ex- amples of Spiniferites, which has a very distinctive and easily recognized morphology (at least at the generic level), have been found in fully freshwater sediments."

Tryon & Tryon (1982: 204) noted that the classification of tree ferns differs among various authors and that the name Cyathea has been used to include nearly all members of the family. The labels on reference slides used for identification often reflect this confusion, especially between Cy- athea and Alsophila. A further complication is that the lip surrounding the laesurae is difficult to observe on some fossil specimens because of pres- ervation and/or orientation. According to recent illustrations by Gastony & Tryon (1976) and Tryon & Tryon (1982), trilete, micropunctate forms with a lip often bordered by punctae are referred to Cyathea, while forms with a laevigate surface be- neath the perine belong to Alsophila. Laevigate spores of similar size and morphology lacking the lip and bordering punctae are produced by several extant genera (e.g., species of Adiantum). Follow- ing this classification, Cyathea spores are known from the Culebra, Cucaracha, La Boca, and Paraje Solo formations (as Alsophila in the latter; Gra- ham, 1976, figs. 16-18). Alsophila is known from the Gatuncillo Formation (Graham, 1985, fig. 10, as trilete fern spore type 1) and from the Paraje Solo Formation (Graham, 1976, fig. 19, as Cy- athea). In Central America Cyathea grows primarily in low rain forests, montane forests, and cloud forests, usually between 1,500 and 2,000 m PTERIDACEAE Pteris. with some 55 occurring in the Neotropics from northern Mexico (Nuevo León) and Florida to Ar- gentina and Chile (Tryon & Tryon, 1982: 334). It usually grows at altitudes below 2,000 m in wet, cloud, or gallery forests. Spores are frequent but not abundant in the Gatuncillo, San Sebastian, Us- cari, Culebra, Cucaracha, and Paraje Solo for- mations. Type 1 (Figs. 8, 9). ces rounded, margin entire to slightly undulating; Pteris is a genus of about 250 species, Amb oval-triangular, api- trilete, laesurae straight, narrow, inner margin en- tire, 23-25 um long, extending to spore margin; wall with coarse irregular verrucae on distal sur- face, proximal surface more laevigate, hyaline mar- ginal flange 12-15 um wide; 62-68 um Type 2 (Figs. 11, 12). Smaller (40-42 um), the marginal flange narrower (4-5 um wide), and the verrucae smaller and more numerous. VITTARIACEAE Cf. Antrophyum (Fig. 14). Amb triangular, apices rounded; trilete, laesurae relatively small in relation to spore diam., um long, extending ca. 75 distance to spore margin, inner margin entire; laevigate; wall ca. 1.5 um thick; 50-52 um Antrophyum is represented by about 10 species in the Neotropics, growing in cloud and rain forests usually at elevations between 100 and 1,500 m from Mexico (Hidalgo) through Central America and the Antilles to northern Argentina and south- eastern Brazil (Tryon & Tryon, 1982: 360). The spores are similar to those of Acrostichum aureum L. (cf. Tryon & Tryon, 1982, figs. 49.10, 12 and 51.8), a species expected in the La Boca and other estuarine formations because it grows in brackish straight, narrow, 12-1 mangrove swamps. The spores of 4. aureum in our reference material (nine collections) have a granular, scabrate sculpture, while those of An- trophyum are more laevigate. The distinction is difficult among fossil specimens, and it is possible that both genera are represented in Gulf/ Caribbean Tertiary deposits. Since the fossils are laevigate, however, they are referred to cf. Antrophyum. Similar spores are known from the Gatuncillo, San Sebastian (not figured in Graham & Jarzen, 1969), Culebra, Cucaracha, and Paraje Solo (as an un- known in Graham, 1976, fig. 227) formations. OTHER TRILETE FERN SPORES Several trilete fern spores were recovered for which biological affinities could not be determined. Three of the more distinctive ones are described below. Type 1 (Fig. 7). Amb oval-triangular, apices rounded, margin entire; trilete, laesurae straight, narrow, inner margin entire, 12 um long, extending ca. % distance to spore margin; laevigate; wall 1.5 um thick; 29-32 um.

Amb oval-triangular to cir- cular; trilete, laesurae straight, narrow, 17-20 um long, extending ca. % distance to spore margin, inner margin entire; finely reticulate; wall 1.5 um thick; 45-48 Type 3(Figs. 16, 17). Amb triangular, trilete, laesurae straight, narrow, 12-14 um long, ex- tending to or nearly to spore margin, prominent lip (partially folds?), inner margin entire; distal surface divided into low, irregular, verrucaelike segments by short, sinuous furrows, proximal sur- face more laevigate; wall 2-3 um thick; 31-33 um. MONOLETE FERN SPORES Reniform, monolete fern spores are common in all Tertiary formations studied for the Gulf/Carib- bean region. They are produced by members of the Blechnaceae, Polypodiaceae, and Pteridaceae and range from Paleozoic to Recent. Five types illustrate the range in sculpture and size. Type 1 Fig. 18; 45 x 32 um) is laevigate; type 2 (Fig. 19; 70 x 46 um) is finely verrucate; type 3 (Fig. 20; 69 x 51 um) has numerous, small, densely arranged verrucae; type 4 (Fig. 21; 42 x 36 um) is coarsely verrucate; and type 5 (Fig. 22; 54 x 36 um) has prominent, widely scattered, peglike verrucae. GRAMINEAE Spherical, amb circular; monoporate, pore cir- cular, 2 um diam., inner margin entire, annulus ca. 2 um wide, outer margin entire; tectate, wall ca. 2 um thick; psilate to faintly scabrate; ca. 3 um (folded) (Fig. 23). The Gramineae ] and the spec- imens cannot be referred to MER single genus. Grass pollen continues to be rare or absent in Gulf/ Caribbean Tertiary deposits studied to date, with only a few grains previously reported from the Culebra and Paraje Solo formations. Specimens are known in the stratigraphic literature as Monopori- tes annulatus and range from the Paleocene (Bra- zil) to Recent (Muller, 1981, 1984) PALMAE Although several surveys of modern palm pollen are available (e.g., Ferguson, 1986; Thanikaimoni, 1970), it is still difficult to identify Gulf/Caribbean Tertiary specimens. The pa component of the vegetation, and three types are recognized for the La Boca Formation. Attalea type (Fig. 24). Wedge-shaped, with greatest diam. near pole; amb ca. rectangular; monocolpate, colpus straight, narrow, 19-22 um long, inner margin entire to minutely dentate; sca- brate; tectate, wall ca. 1.5 um thick; 43-47 x 25-29 um. Attalea is a genus of about 40 species occurring in South America, the West Indies, and the Old World tropics, with one species (4. allenii H. Moore) listed for Panama (D'Arcy, 1987), where it grows at elevations up to ca. 1,000 m lms were a prominent Manicaria type (Figs. 25-27). | Prolate, with greatest diam. at or near equator; monocolpate, colpus straight to slightly sinuous, narrow, 30-42 um long, extending nearly entire length of grain, inner margin entire; finely reticulate (diam. of lu- men | um or slightly less); tectate-perforate, wall ca. 1 um thick; 36-48 x 21-30 um. Manicaria is a tree up to 10 m tall, with three species in the Antilles, Central America, and South America (fide Bailey, 1943), where it often occurs in dense groves in wet places. Similar pollen is known from the Gatuncillo and Culebra formations. Synechanthus type (Figs. 28, 29). Prolate; monocolpate, colpus straight, narrow, 30-42 um long, extending entire length of grain, inner margin entire; microreticulate; tectate-perforate, wall 1.5— 2 um thick; 36-48 x 30-38 um Synechanthus grows in Panama at low eleva- tions in the tropical moist, premontane wet, and premontane rain forests (Croat, 1978: 178). Sim- ilar pollen occurs in the Culebra Formation. AQUIFOLIACEAE Ilex (Fig. 31). Oblate-spheroidal, amb oval to circular, tricolporoidate, colpi straight, 18 um long, equatorially arranged, meridionally elongated, equidistant, inner margin diffuse, pores obscure, diam. ca. 2-3 um, circular, situated at midpoint of colpus; intectate, clavate, wall 3 um thick; 27 x 18 um In Central America /lex commonly grows at mid altitudes in moist to slightly drier habitats. It is a frequent component of Gulf/Caribbean Tertiary microfossil floras in low percentages and has been recovered from the Gatuncillo, San Sebastian, Us- cari, Culebra, Cucaracha, and Paraje Solo for- mations. 58 Annals a eae Garden FicunEs 18-33.

Volume 76, Number 1 1989 Graha 59 La dac Formation—Lower Miocene Communities BOMBACACEAE The pollen of several Bombacaceae are distinct (Tsukada, 1964; Nilsson & Robyns, 1986), but other generalized types cannot be referred to any one genus (see listings in Muller, 1981: 46-48). There is also some overlap with the closely related families Sterculiaceae and Tiliaceae, and in fossil deposits types are recovered that do not match exactly any extant members of the complex (Gra- ham, 1976, figs. 248-255). It is possible that some unidentified pollen represents extant species not yet collected or extinct taxa from early speciation after introduction into the Caribbean region. Fur- ther studies are needed on the pollen morphology of modern forms, including newly described taxa, and a complete assessment should be made of fossil types. Bombacaceae are prominent members of neo- tropical forests, and the pollen is frequent but not abundant in Tertiary sediments. Muller (1981: 46- 48) listed the oldest occurrence of this family as Maestrichtian (uppermost Cretaceous) from the southeastern United States and cited other records supporting Wolfe's (1975) suggestion that the fam- ily originated in eastern North America and sub- sequently spread to South America and Africa where it diversified. In the Caribbean region it first ap- pears in the Paleocene of northern South America (Bombacacidites annae = Bombax ceiba type; Germeraad et al., 1968: 277), and in our material, pollen of the family occurs in the San Sebastian Formation and Uscari sequence.

Prolate; tricolporoidate, colpi narrow, straight, 25 um long, extending near- ly entire length of grain, equatorially arranged, meridionally elongated, equidistant, pore area faint, circular, situated at midpoint of colpus; distinctly and coarsely striate, striae generally oriented par- allel to long axis of grain, surface psilate, margins entire, occasionally appearing beaded from under- lying pores in foot layer /endexine; tectate but with occasional separation between sculpture elements, wall 1.5 um thick; 42-48 x 30-32 um. Crudia is a South American, mainly Amazonian, riverine tree of low altitudes (Cowan & Polhill, 1981: 131). Pollen ranges from the Eocene in northern South America (as Striatocolpites ca- taumbus) and from the Paleocene in Africa (Mul- ler, 1981). It occurs in Central America in the Gatuncillo and Cucaracha formations. Modern pol- len has been studied by Graham & Barker (1981). LENTIBULARIACEAE Utricularia (Fig. 36). Oblate, amb circular; stephanocolpate, colpi 12-16, equatorially ar- ranged, meridionally elongated, equidistant, 15- 18 um long, extending within 8-10 um of pole, inner margin entire; psilate to faintly scabrate; tectate, wall 2 um thick; 34-36 um Utricularia is an annual or stoloniferous peren- nial, insectivorous, aquatic herb growing along the margins of freshwater lakes and rivers, swamps, and marshes from Florida to Mexico and south through the Antilles, Central America, and South America. It is represented by about 12 species in Panama (Taylor, 1976). Pollen also occurs in the Paraje Solo Formation. MALPIGHIACEAE Representation of the Malpighiaceae in the Gulf/ Caribbean Tertiary is analogous to the Bombaca- ceae, wherein several types are present but many do not match exactly modern reference material or species illustrated in the literature. Generally similar modern forms include Banisteria, Banis- teriopsis, Bunchosia, Hiraea, Malpighia, and Mascagnia; but since the specimens are slightly different, they are referred to types 1- Type 1 (Fig. 39). Spherical, amb circular; periporate, pores circular, 3-4 um margin entire; scabrate; tectate, wall 5-6 um thick; 2 um. The distinguishing features of this grain are the very thick wall and the absence of colpi connecting the pores. Type 2 (Fig. 40). Spherical, amb circular; periporate, pores circular, 3 um diam., inner mar- diam., inner gin entire, faint colpi with diffuse, granular margins UN the pores; scabrate; tectate, wall 2 um thick; 35 y These specimens have moderately thick walls and faint connecting colpi. Type 3 (Fig. 41). periporate, pores circular, 1.5- margin entire, colpi with diffuse, E uir margins E amb circular; iam., inner connecting the pores; scabrate, some scabrae point- ed; tectate, wall 2 um thick; 36 um The distinguishing features of type 3 are the moderately thick wall, distinct colpi, and some sca- brae with pointed apices. Type 4 (Fig. 42). periporate, pores circular, 3-4 um margin entire, colpi with diffuse granular margins connecting the pores; scabrate; tectate, wall 5 um thick; 45 um. These specimens differ from the thick-walled type 1 by having distinct colpi. Type 5 (Fig. 43). Spherical, amb circular; periporate, pores circular, 1.5 um diam., colpi with Spherical, amb circular; diam., inner diffuse granular margins connecting the pores, col- pi and pores numerous, giving scalloped appear- ance to outer margin of grain; psilate; tectate, wall 5-6 um thick; 37 um These thick-walled specimens have numerous pores and colpi, and they are psilate.

This unusual specimen may be an aberrant form and cannot be identified to genus. The Malvaceae are represented in the Caribbean Tertiary by Ham- pea/ Hibiscus (probably Hibiscus tiliaceus L.) in the Culebra Formation and are frequent in the Tertiary of northern South America (as Echiperi- porites estelae, late Eocene to Recent). RHIZOPHORACEAE Rhizophora (Fig. 47). spheroidal; tricolporate, colpi straight, 14-16 um, equatorially arranged, meridionally elongated, equidistant, inner margin entire, costae colpi ca. 2-3 um wide, pores elongated equatorially (colpi transversalis), 1 X 4 um, constricted at midpoint of colpus; finely reticulate; tectate-perforate, wall 2-3 um thick; 16-20 x 14-18 um Pollen of Rhizophora has been recovered from the Gatuncillo, San Sebastian, Uscari, Culebra, Cu- caracha, and Paraje Solo formations and comprises 90% or more of some samples. Its fossil record has been discussed by Langenheim et al. (1967), Leopold (1969), and Muller & Caratini (1977), and its occurrence in the Gulf/Caribbean Tertiary was summarized by Graham (1985: 519, 1987a). Rhizophora is indicative of coastal, brackish-water Prolate to prolate- conditions in tropical to subtropical regions. It is known in the stratigraphic literature as Zonocos- tites ramonae and ranges from the late Eocene to Recent. In older Tertiary deposits in Latin America it is replaced by its presumed ecological equivalent Brevitricolpites of unknown biological affinity. RUBIACEAE The Rubiaceae are represented in the La Boca Formation by two similar pollen types typical of several extant genera. These tricolpate, densely sculptured forms are produced by Anisomeris, Chomelia, Guettarda, Terebraria, and others. Type 1 (Fig. 45). Oblate to oblate-spheroidal, amb circular; tricolpate, colpi equatorially ar- ranged, meridionally elongated, equidistant, short (4-5 um apex to equator), often obscured by dense sculpture; reticulate, muri 1.5 um wide, smooth, straight to occasionally curved or slightly sinuous, lumina 2-3 um diam.; tectate-perforate, wall 2 um thick; 26-36 um. Type 2 (Fig. 46). Similar to type 1 but is slightly larger (42-46 um), and the muri are thick- er (ca. 2-2.5 um THEACEAE Pelliciera (Figs. 48, 49). Oblate, amb circu- lar; tricolporate, colpi equatorially arranged, meri- dionally elongated, equidistant, 20-26 um, taper- ing to acute apex, inner margin entire, pore circular, 3-4 um diam., situated at midpoint of colpus, inner margin entire; sculpture variable from finely to coarsely verrucate; tectate, wall 4 um diam.; size variable, 40-60 um Pelliciera is a small mangrove tree of lowland coastal areas from Costa Rica to northwest Colom- bia and Ecuador. In the Tertiary, however, it was widespread in the Gulf/Caribbean and is known from the lower middle Eocene Yellow Limestone Group of Jamaica, the middle(?) to late Eocene Gatuncillo Formation of Panama, the middle to late Oligocene San Sebastian Formation of Puerto Rico, the Oligo-Miocene Simojovel Group of Mexico, and from several localities in northern South America. Several anther-size clusters or fragments (Fig. 49) were recovered, indicating the plants grew in the immediate vicinity of the depositional basin. The presence of Pelliciera pollen in the La Boca For- pon is one of the principal a A between 1l Culebra and C In the e record it is known as Psila- tricolporites crassus and ranges from the Eocene to Recent. Other details of the ecology and geologic record of Pelliciera have been summarized by Graham (1977). UNKNOWNS A number of specimens were recovered that could not be identified. Some of the more distinctive and/or abundant ones are illustrated and briefly described below. Unknown 1 (Fig. 50).

Unknowns 12-15 are similar to pollen of several Anacardiaceae and Euphorbiaceae but cannot be referred to any one modern genus. Unknown 13 (Fig. 63). This type is similar to unknown 12, but the columellae are shorter and finer; consequently, the wall is thinner (1.5-2 um) and the reticulum finer. Unknown 14 (Fig. 64). This type has an even thinner wall (1-1.5 um), a finer reticulum, nar- rower costae colpi, and smaller and slitlike pores (2x4 Unknown 15 (Fig. 65). This type is similar to unknown 14 but is smaller (27-32 x 18-21 um). PALEOCOMMUNITIES AND PALEOENVIRONMENTS Results of the La Boca study are of interest in demonstrating an internal consistency in paleocom- munities, climates, and physiography among four fossil floras in two countries of Central America, as well as consistency with independent plate tec- tonic and paleotemperature data. The lower Mio- cene Uscari (Costa Rica), Culebra, Cucaracha, and La Boca (Panama) floras preserve elements of a mangrove swamp (Pelliciera, Rhizophora) fring- ing the volcanic islands constituting the isthmian region during most of the Tertiary. Freshwater marshes and swamps (palms, ferns, Utricularia) occupied lowland areas behind the mangrove zone. On the adjacent slopes were versions of the tropical wet, tropical moist, and premontane forests (Ly- copodium, Selaginella, Cyathea, Pteris, Ilex, Pseudobombax, Alchornea, and Crudia, with Al- faroa/ Engelhardia likely occupying distant, mod- erate highlands in the region). All available paleo- botanical data are consistent in showing little evidence of dry (including savannah) habitats. Grass pollen continues to be poorly represented (maxi- mum of 156 in one sample from the Culebra For- mation; less than 0.5% in two samples from the La Boca) to absent (Uscaria, Cucaracha forma- tions). If savannahs existed, as suggested by the Volume 76, Number 1 1989 Graham 65 La Boca Formation—Lower Miocene Communities FicunEs 62-65. X-14, 3.— 63. Unknown 13, Pan A Unknown 15, Pan A 16-2, ESF W.36, 2-4 grazing and browsing components of the Tertiary faunas, they were probably short-lived and devel- oped locally as recovery vegetation in response to volcanic activity documented for central Panama in the form of extensive ash, tuff, and basalt de- posits (see further discussion in Graham, 1988b). he affinities of the La Boca flora are clearly with Central America and areas to the north, reflecting the establishment of a land connection between Central America and South America only about 3 Ma. The lack of any paleobotanical evidence for sig- nificant highlands is in agreement with plate tec- tonic models suggesting that elevation of the early volcanic islands and peninsulas gradually increased during the latter part of the Cenozoic, and that the highest elevations (3,475 m in the western moun- tains of Panama; 3,820 m, Cerro Chirripo, Costa Rica) are of recent origin. Altitudes up to about 1,200-1,500 m would accommodate all elements in the four lower Miocene floras known from south- ern Central America. No pollen was being blown, washed, or transported into the depositional basin to suggest dry vegetation or high altitudes in the Gatuncillo, Uscari, Culebra, Cucaracha, or La Boca formations of Costa Rica and Panama. Muller (1959) demonstrated that pollen from a variety of inland and upland communities is transported by rivers and deposited in coastal basins. Palynological data from Puerto Rico and southern Mexico further show that many of these habitats, represented by both wind- and insect-pollinated elements, are in- cluded in the microfossil record if such habitats exist in the region. Fossil pollen from the La Boca Formation, Panama.— 62. 16-1, ESF Q-44, 1-3.— Unknown 12, Pan A 21-1, ESF 64. Unknown 14, Pan A 16-3, ESF W-33, 4.— 65. All taxa identified from the La Boca Formation except Crudia occur in the modern vegetation of Panama. Consequently the paleoenvironment must have been similar to the tropical conditions pres- ently prevailing in coastal, lowland, and moderate- altitude habitats in southern Central America. This is consistent with paleotemperature curves (Savin, 19777; Savin & Douglas, 1985; Savin et al., 1975) that show the Uscari, Culebra, Cucaracha, and La Boca floras were deposited een a iol warm interval just before the si in middle and late Miocene times.

ABSTRACT Psychotria subgenus Psychotria (Rubiaceae) comprises 61 species and eight varieties of understory shrubs and Cent enus is most diverse in Panama (40 s pecies) and Costa Rica small trees in Mexico and Central America. The subg (32 species), with a secondary center of diversity in southern Mexico (26 Ew Eu and "rm (26 cies). Endemism is also greatest in Pan (15 species). Species-rich regions in Cos Ri and EM ma are Beier c species complexes contain on nging species and several species with m uch dents EN Only one species- rich group, the P. calophylla group, lacks a continuously wide-ranging member. Psychotria is a pantropical and subtropical ge- nus of mostly shrubs but also small trees, herbs, and even epiphytes. I presently estimate the num- ber of species to be 1,650, making it the largest zenus in the Rubiaceae; this includes 700 species in the Neotropics (my estimate), 250 in Africa (Petit, 1964, 1966), and 700 in Asia and Oceania (Sohmer, pers. comm.). The present state of its infrageneric taxonomy reflects the lack of understanding of the genus as a whole; all that can be said with some certainty is that subg. Psychotria occurs in all three tropical regions and that each region has one or more groups distinguishable from subg. Psychotria. In Tetramerae (Hiern) Petit (1964, 1966); and in Asia and Oceania, the situation is much more com- plex (Sohmer, 1977). The infrageneric uncertainty extends to delim- itations of Psychotria and related genera; the neo- tropical genera Mapouria, Cephaelis, Uragoga, Naletonia, Nonatelia, and Notopleura have been variously merged with or separated from Psycho- tria. Most of these genera, if included in Psycho- tria, fall within subg. Heteropsychotria and are therefore not relevant here. Mapouria, named by Aublet in 1775, is more critical. The principal use of that generic name was by Mueller-Argoviensis (1876, 1881), who in his Rubiaceae treatment for Flora Brasiliensis distinguished between Ma- pouria and Psychotria; the former corresponded to what is properly considered Psychotria subg. Psychotria, while the latter encompassed Steyer- This paper is an amended portion of my 3 pap Ph.D. the Missouri Botanical Garden.

Annals of the Missouri Botanical Garden mark's Psychotria subg. Heteropsychotria, in- cluding Cephaelis. The discovery by Petit (1964), reaffirmed by Steyermark (1972), that the type species of Psychotria, P. asiatica L., falls well within the Mapouria generic concept makes that genus obsolete. Members of Psychotria subg. Psychotria are distinguished easily from all others in the genus. Three characters serve to enable recognition of the subgenus: (1) the leaves are dry red-brown or some- times dull green, as opposed to bright green; (2) the stipules are usually sheathing and caducous, leaving a small, usually pale ridge often with a fringe of red-brown hairs, as opposed to only slight- ly sheathing and conspicuously persistent; and (3 the seeds, hemispherical in cross section, have two longitudinal furrows on the flat ventral surface and usually four or five (or sometimes an irregular number of) longitudinal furrows on the rounded dorsal surface. Psychotria subg. Heteropsycho- tria has a variety of seed cross sections, none of which can be confused with those of subg. Psy- chotria. Additional characters of whole-plant ar- chitecture show differentiation between the tw neotropical subgenera (Hamilton, 1985), as ie mature fruit color, which is almost always red in subg. Psychotria and usually blue in subg. Het- eropsychotria. The naturalness and monophyletic (or at least ““convex””; see Meacham & Duncan, 1987) nature of subg. Psychotria is not in doubt. In the Neotropics, Psychotria subg. Psychotria consists of ca. 200 species. It accounts for the vast majority of Psychotria species in the West Indies, just under half in Mesoamerica, and perhaps a third in South America, where subg. Heteropsy- chotria is most diverse. Psychotria subg. Psycho- tria in Mesoamerica, the subject of this treatment, includes 61 species, 15 of which are recently named (Hamilton, 1988), and eight varieties. | have sorted the species into eight species-groups; their recog- nition as sections awaits study of the subgenus throughout tropical America. Systematic understanding of species-rich tropi- cal taxa such as Psychotria, Miconia, Piper, Bac- tris, Heliconia, and Anthurium is the critical first step toward understanding geographical patterns of diversity and processes of diversification in the tropics. Psychotria subg. Psychotria appears to be a good index taxon for describing species di- versity in tropical angiosperms as a whole (see Biogeography) and therefore provides a diversity data set of use to conservation planners and natural resource organizations. From an ecological and evolutionary standpoint, one hopes that results of the study of Psychotria can be extrapolated to other diversified tropical taxa. MORPHOLOGY AND TERMINOLOGY In this section, characters and character states are explained and illustrated only as necessary in order to eliminate any ambiguity regarding their use in descriptions and discussions. HABIT Habit states, e.g., "shrub" versus “tree,” are distinguished primarily by size, not by architecture or shape. Even l-meter shrubs in this subgenus are usually treelike in having a main trunk and lateral branch complexes. Architecture of Pana- manian species of Psychotria (both subgenera) has been studied (Hamilton, 1985); three basic types of branching event were found, differentiated by the number and orientation of new shoots to which the terminal node gives rise each growing season. In Type 1 branching, at the terminal node one lateral meristem gives rise to a relay axis that elongates the main axis by sympodial substitution. In Type 2 branching, two (or more) relay axes arise at the terminal node and remain equal, neither new axis assuming the same orientation as the axis that preceded it. Type 3 branching resembles Type A except m one of the new relay axes assumes tion as the parent axis. Most species of subg. Fears shows Type 3 branching in both the vertical and lateral directions; this serves as an additional field character for recognizing members of the subgenus. Two exceptions within the subgenus— P. limonensis and P. tenuifolia— show Type 1 and Type 2 branching, confirming their taxonomic affiliation based on other cha ac- teristics (see Infrasubgeneric eee Ar- chitecture has not been included in the descriptions because it has not yet been studied thoroughly for most species in the field STIPULES Stipules can provide valuable information as to interspecific relationships but prove almost worth- s a source of key characters, since in this subgenus they are usually caducous, or deciduous. he two stipules on opposite sides of a node are frequently united to some degree into a sheath. As the young stem grows, mechanical pressure forces the stipules to sever their basal connections to the stem and subsequently to fall off (Fig. 1). Thus most herbarium specimens have no stipules re- Volume 76, Number 1 1989 amilton 69 Mesoamerican CR subg. Psychotr maining. The stipule scar consists of a ridge, usually pale in contrast to the stem, often with a dense fringe of minute red-brown hairs; the hairs often fall off shortly after the stipule. Exceptions to the above are found in the costivenia group, in which stipules are robust and not sheathing and thus are often found persisting several nodes from the ter- minus, and in the calophylla group, in which the herbaceous and suffruticose species do not grow sufficiently to force the stipules to break free. Stipule shape and size vary considerably, with the general shape, apex, pubescence, an differentiation providing critical cone be- tween species and species groups (Fig. 2). Taxa descriptions include the stipule Lr. along the stem followed by the maximum widt LEAVES Leaf characters are used extensively in this treatment in keys and as recognition characters. A single leaf, if examined critically, can suffice to identify most species in Mesoamerica. Most char- acter states are unambiguous; descriptive termi- nology is from Hickey (1979). Blade measurements are the length followed by the width at the widest point. Venation character states are observed on the undersides of the leaf blades. Secondary vein divergence is the angle formed at the junction of a secondary vein and the midvein, measured on the distal (on the leaf) side of the secondary vein. Most species have curved second- ary veins, so the tangent at the base of the sec- ondary vein was estimated and used. Angles were measured in the middle third of the leaf blade, as they often become more acute towards the base and towards the apex. The character of secondary venation is consid- ered to have basically three states: eucamptodro- mous, brochidodromous, and brochidodromous with a distinct collector vein (Fig. 3). In eucamptodro- mous venation, the secondary veins near the mar- gins do not connect one to another in robust sec- ondary arches or via a collector vein; they instead become less robust and distinct towards the margin and are often connected by a series of arches of tertiary veins (Fig. 3a). If just one connecting arch maintains the robustness of a secondary vein, the venation is said to be bod ipsun (Fig. 3b); consequently, the distinction between eucampto- dromous and brochidodromous is one of degree, and many species show both states. (It may be assumed, unless stated otherwise, that the second- ary arches are near the blade margin.) Much more | FIGURE 1. Caducous stipules being forced to fall from a branch of Psychotria carthagenensis. Only ter io has fallen. Note the ridge and m hairs at the node where the dod base has broken free. (Knapp 4942.) Scale bar = 1 cm distinct and easily differentiated— enough so to serve in the first couplet in the species-identification key—is the third state, brochidodromous with col- lector vein, in which there is a distinct collector vein running straight or slightly undulating near and parallel with the margin (Fig. 3c). (Note that, in keys and descriptions, the second state, “‘bro- chidodromous," should be assumed not to include a distinct collector vein unless it is otherwise stated.) The arc shape of the secondary veins is also described, the states being: a) straight, b) constantly arcuate, and c) straight near midvein then arcuate near margin. The axils of the secondary veins often have tufts of hairs or domatia or sometimes both. The origin and function of domatia is little understood, but the minute holes found in domatia of mature leaves suggest that early instars of some insects may in- habit the cavities (Fig. Annals of the Missouri Botanical Garden NC, etd Ne q vt lo, "bu v » DUNT JT PETI IN NER.

This distinction is often one of degree, as the major difference is that in percurrent tertiary ve- nation the tertiaries joining the secondaries are more robust than the other reticulate veins, then considered quaternary veins. Few species, such as Tertiary veins in subg. Psychotria are generally either: a) orthogonal reticulate, joining each other and the secondaries, intersecting at roughly right angles, or b) percurrent, joining adjacent second- ladderlike effect between them (Fig. aries, making a Volume 76, Number 1 1989 mb. Hamilton 7 Mesoamerican Psychotria subg. Psychotria P. micrantha, have strikingly percurrent tertiary venation. In several species, especially in the cos- tivenia group, tertiary veins known as intersecon- dary veins intersect the midvein between the sec ondary intersections and run roughly parallel with the secondaries. INFLORESCENCES Inflorescences in subg. Psychotria consist gen- erally of panicles of cymes, in which the cyme (dichasium) is the ultimate group of flowers and the panicle comprises the axes leading to the cymes (Fig. 6). The degree of branching of the panicle reflects the maximum branching found in the in- florescence: 2 degrees indicates that there are pri- mary and secondary axes; 3 degrees indicates that there are primary through tertiary axes, etc. (Fig. 6a-c). Similarly, degree of branching of the cymes is also described (Fig. 6d-f). Cymes are often so contracted as to be glomerules of flowers. Bracts and bracteoles are present, though often incon- spicuous, on the axes; bracts subtend branches of the panicle, and bracteoles subtend the cymes. Inflorescence organization provides many of the most useful characters and so is described in great detail (Fig. 7). Secondary axes are borne in ranks along the main axis. The main axis itself is mea- sured; the distance between the base of the main axis and the point of insertion of the basal (first) rank of secondary axes is the peduncle (its length included in the measure of the main axis). Sec- ondary axes are usually two or four per rank; often when there are two or more pairs of axes per rank, the pairs are differentiated into a longer and a shorter pair (Fig. 7a). Often a specified node can have either one or two pairs of axes; measurements of a single pair are included under “the longer pair," while measurements of the "shorter pair" are relevant only when there are two pairs of axes. Sometimes secondary axes are reduced so that a cyme or flower cluster appears sessile on the main axis (Fig. 7b, k). The angle of divergence of the secondary axes (measured as is that of secondary veins) can also provide valuable information: species in the graciliflora group often have ca. 90? angles of divergence (Fig. 7h), and P. stockwellii shows obtuse angles of divergence (Fig. 7i), in striking contrast to the acute angles characterizing most species.

P. olgae, and P. pacorensis. Mountains near the Colombian border support three more: P. philacra (Cerro Tacarcuna), P. rosulatifolia (Cerro Mali and Cerro Pirre), and P. insignis (south of Puerto Obaldia). Three narrow-ranging species, P. lasel- vensis, P. sixaolensis, and P. fendleri, are found in areas of Caribbean lowlands, which have not been botanized thoroughly. It is beyond the scope of this treatment to speculate on the causes of these patterns—e.g., absolute rainfall, topograph- ical heterogeneity, geological disturbance— but the pattern suggests that Costa Rica and Panama de- serve the lion's share of in situ conservation focus in Mesoamerica. The biogeographies of species complexes, within groups, display consistent patterns that suggest hypotheses as to the course of evolution within the complexes (see Infrageneric Relationships). Many species complexes are comprised of one widespread species, for which the complex is named, plus one or more species with much narrower ranges: the Meg quinqueradiata complex (two species), e P. micrantha complex (two species), the P. ud complex (two species), the P. costive- plex (two species), the P species), the P. chiriquina complex (three species), and the P. panamensis complex (six species; see distribution maps in the introductions to each species group in the Systematic Treatment). Seven wide- spread species, such as P. carthagenensis and P. Annals of the Missouri Botanical Garden 105 100 95 i. 90 FIGURE 12. (see Table 2) are shaded. marginata, are not obviously similar to any nar- row-ranging species. Group 8, the calophylla group, defies even tentative analysis of affinities: most species are narrow endemics in Costa Rica and Panama, with only P. calophylla and P. psycho- triifolia having somewhat wider ranges. The pre- dominant pattern of one widespread plus one or more narrow-ranging species accounts for 35 of the 61 species and suggests that in each complex the widespread species may be ancestral to those with narrow ranges. Careful phylogenetic analysis of the subgenus throughout the Neotropics is nec- essary to evaluate this hypothesis. Each species and variety account in the Sys- tematic Treatment includes a characterization of range in terms of habitat and climate. The habitat classification used is that of Holdridge (1967), par- ticularly from life zone maps of Costa Rica (Tosi, 1969) and Panama (Anonymous, 1970). The ranges of many Mexican species are characterized ac- cording to a vegetation map of that country (Flores Mata et al., 1971). Climate types are those of Walter et al. (1960), discussed by Walter (1973); the particular climate types referred to herein are six: I equatorial, I(X) equatorial-mountainous, I(H) equatorial-tropical, II(I) tropical-equatorial, II tropical, and II(X) tropical-mountainous. Equato- rial and equatorial-mountainous climates may show some seasonality of rainfall, but the ratio of pre- Numbers of species of Psychotria subg. Psychotria per one-degree square. Squares of high endemism cipitation (in mm) to temperature (in degrees cen- tigrade) never drops below 2:1 in any month. In an equatorial-tropical climate, there is a mild dry season in which the ratio drops slightly below 2: 1 for one or two months, usually around March. In a tropical-equatorial climate, the dry season is more extreme, lasting up to four months at the beginning of the year. The dry season in a tropical or tropical- mountainous climate usually lasts November through April, some of those months often having absolutely no precipitation. INFRASUBGENERIC RELATIONSHIPS Formal taxonomic recognition of sections awaits understanding of the subgenus throughout the Neo- tropics. For the time being, I have divided the 61 Central American species into eight groups com- parable to sections. In several cases I refer to species complexes, which are sets of morphologi- cally very similar species within a group. The following key to species groups indicates major differences among the groups and is pri- marily didactic; it utilizes characters, such as stip- ules, that are useful at the species-group level but less so for species identification, e.g., because stip- ules are caducous and fruits are often not present. For species identification, one should use the key to species in the Systematic Treatment; it relies Volume 76, Number 1 Hamilton 79 Mesoamerican Psychotria subg. Psychotria largely on leaf and inflorescence characters, which are most consistently evident. Following the key are brief synopses of the eight species groups, including lists of species, geograph- ic patterns, and noteworthy character states not in the key. More extensive descriptions, with distinc- tive character states italicized, plus discussions of species relationships, biogeography, and breeding biology will be found at the beginning of each group in the systematic treatment.

Species 1-7. The carthagenensis group comprises seven species: Psychotria carthagenensis, P. clivorum, P. lamarinensis, P. micrantha, P. neillii, P. quin- queradiata, and P. viridis. The Psychotria quin- queradiata species complex includes that wide- spread species plus P. which is endemic to northern Costa Rica. The P. micrantha complex includes that species plus P. neillii, whose lamarinensis, range is restricted to Caribbean southern Nicara- gua and northern Costa Rica. Psychotria car- thagenensis, P. clivorum, and P. viridis are all widespread without obvious close relatives. In addition to the key characters, members of this group may be recognized by their seeds having (3-)4-5 deep longitudinal furrows on the dorsal surface and 2 longitudinal furrows on the ventral surface. Group 2—costivenia group. Species 8-16. The costivenia group comprises nine species: P. balancanensis, P. costivenia, P. fendleri, P. flava, P. grandis, P. horizontalis, P. papantlen- sis, P. pleuropoda, and P. sylvivaga. The Psy- chotria horizontalis i^a includes the most widespread of the nine plus P. fendleri, which is endemic to Caribbean coastal Panama. The P. cos- tivenia complex comprises the other seven; P. costivenia is only slightly more widespread than P. grandis, with the two sharing noteworthy mor- phological similarity and overlapping ranges. Psy- chotria sylvivaga has been collected only in Costa Rica, and the remaining four species are restricted to southern Mexico, Guatemala, and Belize. Distinctive character states, in addition to those in the key, include a usually conspicuous persistent calyx in fruit. Group 3— graciliflora group. Species 17-25. The graciliflora v bud nine re in Mesoamerica: P. ba , P. graciliflora, P jimenezii, P. laselvensis, P. leia P. margina- ta, P. orosiana, P. parvifolia, and P. philacra. Psychotria marginata is the most widespread and frequently collected, and no other species closely resembles it morphologically. In contrast, the also widespread P. graciliflora is strikingly similar to six of the other species (the P. graciliflora com- plex) that occur more or less sympatrically with it: P. parvifolia and P. orosiana (Costa Rica and western Panama), P. laselvensis (Costa Rica), P bakeri (Los Santos, Panama), P. liesneri (eastern Panama province), and P. philacra (eastern Dar- ien, Panama, at higher elevation than P. gracili- flora). Psychotria jimenezii may belong to this complex as well. Annals of the Missouri Botanical Garden Members may be recognized by their key char- acters plus stipules often biacuminate to biaristate, secondary veins usually brochidodromous and di- verging 70°—-90°, and inflorescence secondary axes usually delicate. Group 4—remota group. Species 26. The remota group includes several species in South America but only one of those, P. remota, in Mesoamerica. An additional recognition char- acter is the winged inflorescence axes, conspicuous especially in the fie Group 5— nervosa group. Species 27-35. The nervosa group comprises nine species: P. aguilarii, P. boquetensis, P. chagrensis, P. eryth- rocarpa, P. fosteri, P. fruticetorum, P. jinote- ensis, P. mirandae, and P. nervosa. Two species complexes, those of P. nervosa and of P. cha- grensis, are discernible; three other fairly wide- spread species— P. fruticetorum, P. erythrocar- pa, and P. jinotegensis—do not closely resemble any others. The P. nervosa complex consists of widespread P. nervosa and three species of more restricted ranges, all of which occur allopatrically with or at range boundaries of P. nervosa: mirandae in southern Mexico, P. aguilarii in higher-elevation southern Guatemala, and P. bo- quetensis in high-elevation western Panama. The 1 P. chagrensis plex includes widespread P. cha- grensis and the probably derived P. fosteri, which occurs on Coiba Island, Panama, apparently allo- patrically with respect to P. chagrensis. Recognition characters not included in the key are ellipsoidal to narrow-ellipsoidal fruit, and inflo- rescences reduced to fascicles of flowers or the secondary axes in (2-)3 ranks. Group 6—panamensis group. Species 36-47. The panamensis group comprises 12 species in Mesoamerica: P. cascajalensis, P. chiriquina, P. cocosensis, P. dwyeri, P. hornitensis, P. lundellii, P. mexiae, P. olgae, P. panamensis, P. sarapi- quensis, P. stockwellii, and P. trichotoma. The largest species complex is the P. panamensis com- plex. It includes one widespread species, P. pan- amensis, whose var. ixtlanensis may owe its origin to introgression from P. trichotoma (see under Systematic Treatment), and five narrow-ranging species: P. dwyeri (southern Mexico, sympatric with P. panamensis), P. stockwellii (Costa Rica and Panama, sympatric), P. cocosensis (Cocos Is- land, Costa Rica, allopatric), P. olgae (Panama, + sympatric), and P. cascajalensis (Panama, sym- patric). The widespread species P. trichotoma, P. sarapiquensis, and P. mexiae are of uncertain affinities; the former two may be closely related to . panamensis complex. The P. chiriquina complex includes two species whose ranges do not overlap (P. lundellii south to El Salvador and P. chiriquina south from northern Nicaragua) and one narrow endemic, P. hornitensis from high- the elevation western Panama at the eastern end of the range of P. chiriquina. Group 7 —tenuifolia group. Species 48, 49. The tenuifolia group includes only two species in Mesoamerica, P. limonensis and P. tenuifolia, both of which are widespread with extensively over- lapping ranges. The group is characterized by mi- nute flowers and secondary veins diverging usually 70-90", in addition to the key characters. roup 8—calophylla group. Species 50-61. The calophylla group comprises 12 species: P. alfaroana, P. calophylla, P. chitariana, P. dress- leri, P. hammelii, P. insignis, P. insueta, P. mon- teverdensis, P. pacorensis, P. psychotrüfolia, P. rosulatifolia, and P. sixaolensis. Ten of the species have small geographic ranges; only P. calophylla and P. psychotriifolia are at all widespread, and their ranges are notably discontinuous. Psychotria dressleri and P. rosulatifolia are quite similar mor- phologically and occur in eastern Panama, and therefore may be supposed to be related; but be- yond that the affinities are very uncertain. Additional recognition characters are many: her- baceous or suffrutescent habit; usual general pu- bescence; sheathing stipules, these usually bifur- cate or biaristate with the extensions often from corners of the truncate sheath; and ellipsoidal fruit.

Shrubs, small trees, or less often herbs or sub- shrubs; stipules interpetiolar, often sheathing, usu- ally caducous, leaving a pale ridge with red-brown fringe. Leaves opposite; blades membranous to co- riaceous, drying red-brown or dull greenish or rare- ly chalky yellow- ies secondary veins eucamp- todromous to brochidodromous, sometimes with collector vein, the um sometimes with domatia or tufts of hairs; tertiary veins orthogonal reticulate to percurrent. /nflorescences terminal or pseu- doaxillary, panicles of cymes or of glomerules or rarely fascicles of flowers; secondary axes borne in 1-several ranks along the main axis, each rank with 1-3 often size-differentiated pairs of axes. Flowers small, (4—)5-merous, almost always disty- lous; corolla usually white, the tube cylindrical; style 2-branched, the branches bearing the stig- matic surfaces, the ovary 2-celled, the ovules 1 per cell, attached basally. Fruit fleshy, maturing red (except reportedly purple or blackish in insueta and P. pacorensis); persistent calyx often conspicuous at distal end of fruit; seeds 2, hemi- spherical in cross section, the rounded dorsal sur- face with 3-5 regular to many irregular longitu- dinal furrows, usually giving the dried fruit a costate aspect, the flat or slightly concave dorsal surface with (1—)2 regular longitudinal furrows often plus several shallow irregular furrows. A pantropical subgenus of approximately 600 species worldwide, including ca. enus accounts for the majority of species in ihe Antilles but only for 32 of 242 species treated by Steyermark (1972) for the Guayana Highland.

Psychotria clivo- rum shares many character states with P. car thagenensis, but the former differs in having sti- pules often biaristate, larger elliptic (versus obovate) leaf blades, more secondary veins, often brochi- dodromous secondary venation, and larger inflo- in size uni- rescences. Stipule morphology varies geographically, as Guatemalan plants appear more often biaristate while Nicaraguan plants have exceptionally large stipules. Secondary venation is generally eucamp- todromous, but in Nicaragua the secondary loops are sufficiently robust to appear brochidodromous. 3. Psychotria lamarinensis C.

Psychotria lamarinensis may be recognized by its large, broad-elliptic leaves with the base nar- rowly subcordate, reduced globose inflorescence drying red-brown, and broad-ovate stipules. Psy- chotria lamarinensis may be a local derivative from P. quinqueradiata, from which the former differs in having much larger leaves with secondary veins diverging 709-85? instead of 45°-60° and shorter (3 mm vs. 4-5 mm) corolla tubes. Only a short-style flower morph has been seen, but only two flowering collections do not suffice to suggest that the species is thrum-monomorphic. 90 Annals of the Missouri Botanical Garden 4.

Psycho- tria neillii differs from P. micrantha in having smaller (10-18 vs. 20-32 cm long) mature leaves with fewer (12-15 vs. 20-26) secondary veins, delicate inflorescence axes, and larger (5-7 mm vs. 4 mm long) fruit. All three flowering collections are thrums; ad- ditional collections are necessary to determine whether the species is distylous or thrum-mono- morphic. 6.

Psychotria quinqueradiata and P. morae were published simultaneously by Polakowsky and serve as the only instance known to me where pin and thrum morphs of the same species were named as different species. I chose to retain the former ep- 94 Annals of the Missouri Botanical Garden ithet for its reference to the five equal axes ra- diating from the base of the inflorescence, an im- portant recognition character (Fig. 7g). The glabrous, obovate leaves drying red-brown to green-brown, with secondary veins usually brochidodromous making loops far from the mar- gin, also aid in recognition. Psychotria quinque- radiata resembles P. carthagenensis in most veg- etative and fruit characters but differs in its distinctive inflorescence and brochidodromous ve- Stipule shape is invariable in the range of the species, but size varies greatly, from the typical 4-6 x 2-3 mm in Nicaragua and Costa Rica to 4-6 X 5 mm in Panama to 10-15 x 8 mm in Guatemala. 7.

Psychotria viridis may be readily recognized by its inflorescence: all ranks of secondary axes except the first and second are reduced so that flowers and fruit appear in clusters along the main axis (Fig. 7k). Psychotria viridis is, in its vege- tative and fruit characters, almost identical to P. carthagenensis; the distinctive inflorescence may be viewed as a reduction in secondary and tertiary axes of that of P. carthagenensis. There appears to be only one flower morph, a homostyle, in Central American P. viridis, with no spatial separation between the exserted anthers and stigma. Leaves in Guatemala and Belize have fewer secondary veins than elsewhere in Central America. GROUP 2. THE COSTIVENIA GROUP Shrub or tree; young stems glabrous or puber- ulent or rarely tomentose or ferrugineous-pubes- cent; stipules usually not sheathing, ovate, uniform color or often with a pale central triangle or keel (Fig. 2b), glabrous or puberulent or ferrugin- eous-pubescent or sometimes fringed, caducous or often persistent at terminal 2-6 nodes. Leaf blades elliptic or ovate or obovate or oblanceolate, drying usually yellow-green or sometimes green, green- brown, or red-brown, often dull or pale, sometimes chalky above, sometimes darker below; T veins (6-)7-19(-21) pairs, er (45 85°, eucamptodromous or We 5 the axils usually lacking domatia or duis (except some- times P. horizontalis and P. sylvivaga); tertiary veins orthogonal reticulate or less commonly per- current, the intersecondaries often conspicuous, the tertiary loops sometimes evident (P. fendleri and P. horizontalis). Inflorescences panicles of cymes or rarely of glomerules (P. flava), pedun- culate (except rarely in P. horizontalis); second- ary axes usually in 2 or 3 size-differentiated pairs per rank (Fig. 7b) or sometimes 2 or rarely 4 subequal; bracts not conspicuously enlarged (to 5 mm long in P. flava and P. pleuropoda). Corolla tubes 2-3.5 mm long (4-5 mm in P. papantlen- sis), the lobes without apical extensions. Fruit when dry spherical to ellipsoidal (sometimes slightly ob- ovoid in P. flava); persistent calyx a beak or a tube Fig. 9b) or of linear lobes (Fig. 9e) or not evident, over 1 mm long only in P. fendleri and P. horizontalis; dorsal seed surface with 3-5 reg- ular (Fig. 10b) or 6-15 irregular longitudinal fur- rows (Fig. 10i, j), the ventral surface with 2 often incompletely divided longitudinal furrows (Fig. 10e) or one often T-shaped longitudinal furrow (P. flava; Fig. 10j) rarely plus 4 irregular longitudinal furrows (P. sylvivaga). This subgroup may be subdivided into two species complexes. The Psychotria horizontalis complex includes the widespread P. horizontalis and P. fendleri, the latter endemic to Caribbean coastal Panama (Figs. 16, 17); they share the distinctive character states of immediately caducous stipules, brochidodromous secondary venation with con- necting loops far from the blade margin plus evident tertiary connecting loops, and persistent calyx at least 1 mm long. The P. costivenia complex, which includes the remaining seven species, has in com- mon often persistent stipules usually with a paler central triangle or keel, often conspicuous inter- secondary veins, and persistent calyx a beak or tube no longer than 1 mm. Two species are wide- spread— P. costivenia (Mexico through Nicara- gua; Fig. 18) and P. grandis (Guatemala through Panama; Fig. 19), both also in the Greater An- tilles—and five have small ranges: P. balanca- nensis (Tabasco, Mexico; Fig. 19), P. flava i ern Mexico and Petén, Guatemala; Fig. 17), P papantlensis (southern Mexico through Belize; Fig. 16), P. pleuropoda (southern Mexico through Be- lize; Fig. 17), and P. sylvivaga (central Costa Rica; Fig. 17) Of the nine species in the group, six appear distylous; two of those, Psychotria papantlensis and P. pleuropoda, show some between-morph asymmetry in floral part lengths. Only one species, P. fendleri, apparently has evolved a derived state, thrum-monomorphy. Too few specimens of P. lancanensis have been seen to determine its breed- ing system. 8.

It was collected in flow- er in early June. Known only from the Psychotria balancanensis may be recognized by its moderate-sized (7-11 cm long) broad-elliptic leaves drying dull green to green-brown with con- spicuous intersecondary veins and by its inflores- cence with the secondary axes in two ranks near the apex of the main axis. This species differs from P. costivenia in having broader-elliptic leaves and smaller inflorescences with fewer (two vs. four) ranks of secondary axes. Only the pin morph has been collected, but the one flowering specimen seen is not sufficient to suggest that the species is pin-monomorphic. 9. Psychotria costivenia Grisebach, Pl.

Leaf blades from Zelaya, Nicaragua, at the southern end of the geographical range, have 15- 18 secondary veins, numbers rarely reached in the rest of the range. Inflorescences tend to be smaller in Honduras, El Salvador, and Nicaragua than farther north. The corolla appears generally wider (2 mm) in Honduras than in the rest of the range. 10.

Veraguas: Isla de Coiba, 16 Aug. 1961 (early fr), Dwyer 1540 (MO) ~ Psychotria grandis may be recognized by its large size (to 10 m tall), robust keeled stipules with margins reflexed and usually persistent at terminal 3-6 nodes, large (17-32 cm long) leaves with conspicuous intersecondary veins, large robust in- florescences, and fruit drying spherical and smooth, the latter due to the seed dorsal surface having many shallow irregular furrows instead of few deep furrows (Fig. 10i). The distinction between this species and P. costivenia 1s somewhat problematic, as it Is based largely on quantitative characters, such as leaf and stipule and inflorescence size. Differences in seed cross section (10-15 irregular vs. 4-5 deep regular furrows on dorsal surface) support the distinction. The two species occur sym- patrically only in northern Guatemala and southern elize. General puberulence is common only in Belize and Honduras. Material from Belize has the longest stipules; Guatemalan material has the largest in- florescences; and Nicaraguan fruit is generally larg- er than elsewhere. 13.

S, All the species in synonymy have been properly synonymized before (cf. Dwyer, 1980). Infraspe- cific categories are not recognized herein because they have been defined in terms of variation seen within almost any population, such as the basicor- date leaf blades on which P. horizontalis subsp. basicordata was based. Psychotria horizontalis may be recognized by its leaves drying usually dull pale green, with sec- ondary veins brochidodromous and making con- necting arches far from the margin (Fig. 3b), and by its fruit with conspicuous persistent calyx of long, linear lobes (Fig. 9e) Material from Guatemala, Belize, and Nicaragua is generally more pubescent than elsewhere in Cen- tral America. The calyx lobes, prominently persis- tent in fruit, are often much shorter in central Panama than elsewhere. 14. Psychotria —€— a Hems- ley, Biol. Cent. Amer. Bot. 50. 1881.

The new genus differs eta enta staminate perianth and in seed shape and seed coat structure. with Evodianthus (e.g., separate fruits, terminal inflorescences, ote eh of these uncommon charact appendages. Although Dianthoveus and Dicranopygium sub. Diant ers but e shares only laminar anther genus Gleasonianthus uniquely share staminate flowers h with eglandular tepals, no other characters suggest a close relationship between them. Exploration of tropical wet forests in southern Central America and northwestern South America in recent years has greatly increased the number of collections and species known from these areas. This was especially predictable for the Cyclantha- ceae, which are restricted to the wettest, often least-explored habitats (Grayum € Hammel, 1982). Since the time of Harling's (1958) monograph, which included 178 species in 11 genera, 29 new species have been added to this predominantly epi- phytic family. More than 30 additional new species are now known from Central America and the Chocó region of South America alone (Hammel, unpubl.). However, only one new subgenus (Wilder, 1978) and no other supraspecific taxa have been described. In fact, in recent years only 10 genera have been recognized; Pseudoludovia is thought to be a mixed collection: a spadix, perhaps of a Sphaeradenia, and leaves of Ludovia (Wilder, 1978). Harling suggested that on further study it might be possible and logical to subdivide the three largest genera into additional genera, and for Sphaeradenia this reclassification is imminent (R. Eriksson, in press). Dianthoveus, the name an anagram of “Evodianthus,” is a totally novel, monotypic genus. This plant was first described and illustrated, as a short-stemmed terrestrial, in The Flora of the Río Palenque Science Center (Dodson & Gentry, 1978), where it was identified as Asplundia va- gans Harl., a common root-climbing epiphyte of Central and South America. Examination of spec- imens of Cyclanthaceae in the herbarium at the Marie Selby Botanical Gardens, where vouchers for the Rio Palenque florula are deposited, revealed that the plant was neither poorly illustrated nor a terrestrial form of A. vagans, but rather something problematic, exhibiting unusual characters of sev- eral genera. This stimulated two field trips to Ec- uador, which, along with laboratory studies, con- vinced us that the plant is an undescribed genus. MATERIALS AND METHODS In total, well over 200 individuals in seven pop- ulations were examined in the field. Plants at var- ious stages—from early anthesis through ripe in- fructescences to peduncle remains—were fixed in or anatomical and morphological studies. Twenty-eight fluid-preserved collections at these stages were made, and numerous herbarium vouch- ers and live plants were collected. In the field, live specimens were examined to determine inflores- cence position, presence/absence of latex, drying qualities of wounded and air-dried leaves, and fea- tures of leaf color and texture.

Volume 76, Number 1 1989 Hammel & Wilder 113 Dianthoveus Plants preserved in the field in FAA were drained of fluid and transported in sealed plastic bags within a large plastic container. Subsequently they were washed in water for several days and then stored in an aqueous solution of 5% glycerin and 50% ethanol. All measurements were taken from live or fluid-preserved plants at populations along the Río Pilatón (Hammel & Wilder 16058, 16059, 16066, 16067 & 16074). Leaf measurements were taken from a total of 17 adult leaves from three individ- uals. Inflorescence measurements were taken from four individuals, and flower measurements come from ten flowers in each inflorescence. Infructes- cence measurements were from ten individuals, and fruit measurements from ten fruits in each of four individuals. For anatomical studies, material of lam- inae, roots, and stems was prepared according to the methods of Wilder (1985). Seeds were taken from mature preserved infructescences embedded in Tissue Tek OTC polysaccharide compound, fro- zen, and sectioned in a cryostat. Sections were mounted, stained with toluidine blue, and viewed with a bright field microscope. Pollen was prepared with and without acetolysis and with and without critical point drying, coated with gold, and viewed with a Hitachi S45D scanning electron microscope. Detailed studies on the morphology and develop- ment of vegetative parts and inflorescences, and the anatomy of laminae, first-order roots, and rhi- zomes are in progress (Wilder, unpubl.). In order to test our initial hypothesis of rela- tionship of the new genus to Evodianthus we se- lected 22 characters for the 11 genera of Cyclan- thaceae (Table 1), developed a character-by-taxon matrix (Table 2), and analyzed the data using PAUP for microcomputer, a maximum parsimony tech- nique (Swofford, 1985). All characters were un- weighted, but the four character states of “habit” were restricted to a specific order (Table 1 and discussion below). Since no logical basis was ap- parent for restricting the order of character trans- formations of other multistate characters, all other characters were treated as unordered. Characters with variable states for a particular genus were coded as missing (Pimentel & Riggins, 1987). Aut- apomorphies for each of the genera were not in- cluded in the analysis. Collections made in December 1988 were added in proof and not considered in the counts and measurements. ‘TAXONOMY Dianthoveus cremnophilus Hammel & Wil- der, gen. et sp. nov. TYPE: Ecuador.

Dianthoveus cremnophilus is robust, short- stemmed, and terrestrial (Fig. 3) but, as indicated by its epithet, it is a “cliff-loving” plant (Fig. 4). At many of the sites along the Rio Pilatón we were able to collect plants only by pulling ourselves up nearly vertical slopes, using roots and stems as hand holds. Several large populations, including the type, were growing on dripping and mossy rock walls. All of the sites were along small streams or gullies or on wet, shaded slopes in isolated patches of relatively undisturbed forest. Even at Río Palen- que, where the terrain is essentially a rolling plain, exposed by recent inns of forest cover and showed signs of sun dam Although Dian omie is locally abundant and probably formerly occurred throughout the wet lowlands and foothills of the Andes in northern Volume 76, Number 1 Hammel & Wilder 1989 Dianthoveus FIGURES 3, 4.

Habitat; plants were often abundant on wet, vertical slopes. 118 Annals of the Missouri Botanical Garden Ecuador, it seems not to occur outside of that area. Attempts to find it have failed on the Amazonian side of the Andes in southern Colombia near Mocoa in Putumayo Province, and in the Pacific lowlands of southern Colombia (near Barbacoas) in habitat similar to that of the adjacent Ecuadorian localities. Phenology. Nearly all of the collections of Dianthoveus have been made from June through December, which spans the primary dry season for humid areas of northwestern Ecuador (Dodson & Gentry, 1978). Our search of numerous large pop- ulations at five different localities during June re- vealed four phenological classes: (1) most plants bore no outward sign of fertile structures (N — ca. 200) except for some with old peduncle stubs; (2) next most abundant were plants with remnants of old infructescences, primarily long-rotten pedun- cles (N = ca. 30); (3) we saw and collected only 12 individuals with young to mature infructes- cences, and (4) five individuals with immature to old inflorescences. At the type locality, only fruiting plants were observed in December of 1986 and in June of 1987. The single mid wet season collection has a young infructescence. Individuals apparently bear a single inflorescence per rhizome at one time. Our studies suggest that Dianthoveus flowers and fruits sporadically throughout the year. From the relatively frequent plants with peduncle remnants during June, we infer a somewhat higher flowering frequency during January through March, i.e., in the middle of the rainy season, a common pattern in other Cyclanthaceae. Development and morphology of fertile struc- tures. The peduncles are most flexible at the base and are held erect at anthesis by the tightly over- lapping leaf sheaths. Later, as the infructescence becomes heavier, the elongating peduncle bends so that the mature infructescence is held either hor- izontally or nearly pendent. The peduncle is per- sistent long after the fruits have been shed, and plants are often found with the fibrous remains of peduncle firmly attached to the rhizome. Both con- spicuous and inconspicuous spathes persist into very late flowering stage with the largest, lowermost spathe persisting longest. Spathe scars are indis- tinct. The fruits of Dianthoveus remain green or be- come light brown at maturity and apparently offer little attraction to dispersers; they are neither fra- grant nor very juicy. We found seeds germinating in the debris of an old infructescence at the base of a plant, and often seedlings were found on wet rock walls below the mother plants. Such gravity or "flush dispersal” is probably usual for the genus; however, we found several fruits on one infructes- cence with the distinctive prints of bat teeth. In Evodianthus the berries become bright pale orange and very juicy at maturity and are undoubtedly dispersed by birds or bats. Staminate flowers are tightly crowded among the pistillate flowers throughout development and persist into the early stages of fruiting; remains of the pedicels can be found even among mature fruits. Tepals often vary in length within one flower and usually with a tendency for the longest tepals to be together, making the flower slightly asym- metrical. This asymmetry, however, appears to be random with respect to the associated pistillate flower; the longest tepals, for example, may or may not face the pistillate flower. The tepals are thin and become brown at anthesis. They are always without resin glandules. Tepals of the pistillate flowers are quite similar in shape and texture to those of the staminate flowers, an unusual condition for the family. Their apices are thin, nearly filamentous, and at first lie closely appressed to the stigmas and to the stamino- dia. In fruiting stages the tepals become much broader—only acute to rounded—and the tips often break off, leaving an irregular ridge around the stigmas, which no longer protrude and are often turned upward rather than uncinate. The sides of the fruit converge basally towards the long axis of the spadix into a narrow, vertical, lenticular shape. Relationships. A simple comparison of the new genus with others in the family suggests that it is closely related to Evodianthus. Most notably, both genera and no others have leaves that are scabrous when dry. Anatomically, this translates into “styloid sacs [which] are normally elongated in all directions within the mesophyll, routinely crossing cell layers" (Wilder, 1985). All other Cyc- lanthaceae with styloid sacs have them elongated only parallel to the longitudinal files of parenchyma cells and confined to one layer. Only Evodianthus and Dianthoveus have styloid sacs in roots. Pollen of both genera is the smallest in the family and inaperturate (Figs. 5, 6), in contrast to the aper- turate pollen of all other genera. Both genera have very short or no filaments and lack basal bulbs. Both have unicostate or cryptically subtricostate leaves, separate fruits, symmetrical staminate flow- ers, and terminal inflorescences, characters un- usual in the family but shared with other genera (Table 3). Features of staminate flowers and seeds have been especially important for delimiting supra- specific taxa within the Cyclanthaceae (Gleason, Volume 76, Number 1 Hammel & Wilder Dianthoveus FIGURES 5-8.— 5.

In the new genus, characters of both these structures differ markedly from those of Evodianthus, from which the former differs by its lack of a biseriate perianth (unique to Evodianthus), its lack of a funnelform receptacle in the staminate flowers (found in Evo- dianthus and several other genera), and by its only moderately flattened and narrowly elliptic seeds (Fig. 7). Evodianthus, as well as Asplundia and Thoracocarpus, have broadly elliptic, strongly flat- tened seeds. The seed coat structure also differs markedly from that of Evodianthus (see below). The new genus is further distinguished by the eglan- dular, acuminate tepals of the staminate flowers (which are similar only to those of Dicranopygium subgenus Gleasonianthus), the apiculate laminar appendages of the anthers (shared only with Schul- tesiophytum), and especially the peculiar papillate receptacle of the staminate flowers (Fig. 8). Seed coat structure is variable among genera of Cyclanthaceae and was an important consideration in Harling's delimitation of genera in the family. We have interpreted the wall layers by focusing on the inner and outer cuticles, described by Har- ling and present in all genera. The seed coat of Dianthoveus (Fig. 9) is similar to those of Car- ludovica and Thoracocarpus; the innermost layer of the outer integument in all three genera has relatively large thin-walled cells with spinulose wall ingrowths on the inner tangential walls, whereas Evodianthus lacks these spinules (Harling, 1958: 38-43) Evodianthus occurs rarely as a terrestrial plant and rarely with leaf blades nearly as large as those of the new genus. With fresh material, the less glossy (more satiny) aspect of the upper leaf sur- face, the larger size, and constantly terrestrial and short-stemmed habit of Dianthoveus distinguish it vegetatively from Evodianthus. Due to the simi- larity of these two genera, Evodianthus specimens (and all other Cyclanthaceae) at COL, F, MO, QCA, and SEL were examined to see if the new genus was included among them; it was not. PHYLOGENETIC ANALYSIS The Cyclanthaceae are widely considered to be monophyletic (Dahlgren et al., 1985; French et al., 1983), and for the most part each of the 11 genera also has at least one clear apomorphy sup- porting its monophyly. Within Cyclanthaceae, Cy- clanthus possesses many unique and highly derived features (Dahlgren et al., 1985; Harling, 1958; ider & Harris, 1982) and apparently shares only ancestral characters with other genera.

Cyclanthus contains only two species and is monomorphic for the characters analyzed; variability within the hypothetical ances- tor was therefore not a problem. Characters not obviously comparable between the two subfamilies, e.g., floral symmetry (Cyclanthus lacks distinct, meristic floral units at maturity) were coded either by looking outside the family to the Araceae, Are- caceae, and Pandanaceae, where Harling and oth- ers have indicated the most likely affinity with the Cyclanthaceae, or by designating them as missing characters for Cyclanthus Harling's (1958) lecum relationships among genera in his *Asplundia group," which would include the new genus, by his own admission were quite tentative (Fig. 10). The main purpose of our analysis was to make an explicit statement as to the placement of Dianthoveus within the family, using characters from Harling and new characters. Discussion of those aspects of the character anal- ysis not directly pertinent to the new genus and comparison of the phylogeny produced with these methods to that of Harling will be presented else- where (Hammel, unpubl.). Character coding. Several characters were coded as missing in Cyclanthus, the hypothetical ancestor for this analysis. For example, althoug the pistillate **units" seem to demonstrate a re- markable extreme of fusion among parts, they readily dehisce from each other at maturity. Fur- thermore, it is difficult to judge an immediate an- cestral state for this character from outgroup com- parison; fruits are commonly fused in Pandanaceae, that whe g (1983) sd "iudei c fruits" as a possible syn- apomorphy for their Areciflorae complex (Areca- ceae, Cyclanthaceae, Pandanaceae), the berries in most species of Cyclanthaceae are dehiscent by apical caps (Thoracocarpus, all but one species of Asplundia, and most species of the Sphaeradenia group; Hammel, unpubl.). Live, mature infructes- cences of Pandanaceae, especially Freycinetia, need to be examined for comparison. Characters of the staminate flowers were like- wise difficult to polarize with reference to Cyclan- thus, which at maturity has only amerous rows of stamens. Pandanaceae also have amerous and ape- talous staminate inflorescences. Flowers were cod- ed as primitively symmetrical by reference to Ar- aceae and Arecaceae. Presence/ absence of glands on tepals and shape of perianth were coded as missing data. The phyllotaxy in Cyclanthus is spirodistichous (Wilder, 1981), making the coding of this char- 122 Annals of the Missouri Botanical Garden r CYCLANTHUS IIS ] C DH _ N S-c GHI BDE ” DICRANOPYGIUM | HH LUDOVIA FIGURE 11. Cladogram of the NARRA Wide half-bars are synapomorphies of character Le above bars refer to characters (Table nown autapomorphies not included in analysis acter problematic; genera of the Carludovicoideae have either orthodistichous (in a few species spi- rodistichous) or spiral phyllotaxy. The Pandana- ceae have tristichous phyllotaxy. For this analysis spiro- and orthodistichy were both subsumed under the category "'distichous," and phyllotaxy was cod- ed as having only two states. The terminal inflo- rescences of Cyclanthus seem well supported as ancestral; terminal inflorescences are the rule in Araceae (Ray, 1987 and pers. comm.) and in Pan- danaceae (Tomlinson & Wilder, 1984) and are characteristic of the “primitive” coryphoid palms. In palms, however, terminal inflorescences are nev- er evicted by axillary shoots (Tomlinson & Wilder, 1984). States for seed characters were coded di- rectly from Cyclanthus as ancestral; the similarity of seeds of Cyclanthus, Dicranopygium, and Lu- dovia with those of some members of the Pan- danaceae is one of the main features that Harling (1958) saw as indicating a close relationship be- tween Pandanaceae and Cyclanthaceae. The branched order of character states for **hab- it" (Table 1) is rationalized by the observation that variable taxa almost always include terrestrial members. It then seems unlikely that any nonter- restrial form was derived one from another. RESULTS AND DISCUSSION From our data matrix (Table 2), PAUP found sister-group relationship between Dianthoveus and ba states found elsewhere in the family or reversed within 1), numbers below rphies discovered by analysis.

Length of terminal clade is Evodianthus is supported by all of these analyses. urthermore, when the data matrix is changed to Become different possibilities for states coded as "missing" or different interpretations of prob- lematic characters for the hypothetical ancestor, such as fruit fusion and phyllotaxy, this relationship remains unchanged even when the overall topology changes. The highly corroborated sister-group relation- ship between Evodianthus and Dianthoveus allows a rational discussion of homologies of the unusual staminate flowers in the new genus. On the basis of our hypothesis (Fig. 11), Dianthoveus appears to retain more relatively primitive character states than Evodianthus, such as the terrestrial (vs. climbing) habit. The moderately flattened seeds are also relatively primitive as compared with the strongly flattened seeds of Evodianthus. The lam- inar-apiculate anther appendages of Dianthoveus could be symplesiomorphous with those of Schul- tesiophytum, but that assumption would require an additional step; it is more parsimonious to as- sume that this kind of anther evolved independently in the two genera. The biseriate perianth of Evo- dianthus—an apomorphy for Evodianthus not in- cluded in the analysis— appears to be derived with- in the family. From this basis we can argue that the inner cycle of the biseriate perianth of Evodianthus might be an elaboration of the unusual papillate recep- tacle of Dianthoveus. By this hypothesis, the lobes of the inner perianth of Evodianthus are not ap- pendicular organs (leaf homologues), but rather Volume 76, Number 1 1989 Hammel & Wilder 123 Dianthoveus emergences, equivalent developmentally to the pa- pillae, which compose cupules in Dianthoveus. In all cases, regardless of coding, eglandular staminate tepals appear to have arisen twice within the Carludovicoideae—in Dicranopygium subge- nus Gleasonianthus and in Dianthoveus. How- ever, according to Harling (1958; see also Wilder, 1978), the eglandular tepals of subgenus Gleason- ianthus are not “real perianths,” but rather are homologous with stamen filaments; he found that lobes of this ““false perianth" sometimes bear re- duced anthers. In addition, the filaments of anthers in subgenus Gleasonianthus are somewhat flat- tened and acute, resembling the lobes of the false perianth. In Dianthoveus we see no equivalent basis for hypothesizing a staminodial nature for the eglandular tepals. We found none with reduced anthers, and they certainly bear no resemblance to filaments of stamens (Dianthoveus lacks fila- ments). Based on their position, they appear simply to be homologous with the glandular outer whorl of the biseriate perianth of Evodianthus and the "real perianth” of other Cyclanthaceae. Under this reasoning, the eglandular tepals of Dianthoveus are similar to those of Dicranopygium subgenus Gleasonianthus only by convergence. CONCLUSION Before our cladogram or any other is presented as a phylogeny for the family, several of the char- acters and character states need to be re-evaluated and the hypothesis tested with additional charac- ters. For example, the character of spathe position, crucial for placing Dicranopygium in the clade definied by clustered spathes, is somewhat subjec- The spathes of Carludovica, Schultesio- phytum, and Dianthoveus are not much closer tive. together than many species outside the clade. Which other, if any, multistate characters (e.g., seed shape) might logically be ordered? One also wonders if characters such as inflorescence position and phyl- lotaxy, which seem to encompass a large suite of characters, should be given extra weight or broken into several characters. All of this needs to be evaluated within the context of a hypothetical ancestor postulated on the basis of taxa outside the Cyclanthaceae. though a close relationship between Dian- thoveus and Evodianthus was suggested initially by the observation that only these two have sca- brous leaves, a phylogenetic analysis using parsi- mony demonstrates the hypothesis as supported b numerous characters. It also provides a logical basis for suggesting the El homologies of the unusual floral features of t ew genus, in par- ticular, the papillate je (possibly homolo- gous with the inner perianth of Evodianthus), the laminar apiculate anthers (evolved in parallel to those of Schultesiophytum), and the eglandular tepals (convergent with those of Dicranopygium subgenus Gleasonianthus).

El carácter más conspicuo lo o. Tal disposición no había r a el micrópilo. El endospermo es de tipo nuclear. El embrión en la semilla madura es poco ABSTRACT candonia schismatica comprises a new family, genus, and species. lts most conspicuous character is the central position of the androecium, surrounded by the apocarpous as not been recorded before er endosperm is of the nuclear type. The embryo of the mature seed is poorly developed. The fruit is indehiscent. La nueva familia Lacandoniaceae del orden Triuridales (Martínez y Ramos, 1989) es afín a Triuridaceae Gardner (Maas y Rübsamen, 1980) pero se diferencia por el gineceo que rodea al androceo y la dehiscencia introrsa de las anteras. La inversión de posición de los órganos repro- ductores fue lo suficientemente interesante para iniciar los estudios estructurales. A continuación se presentan los primeros resultados al respecto. MATERIALES Y METODOS Se estudió material de dos colectas (E. Martinez M. 19310 y 21822) de Lacandonia schismatica E. Martinez y C. H. Ramos. Se fijaron muestras de botones florales, flores, y frutos en diversas etapas de desarrollo en el sitio mismo de colecta (selva Lacandona, Chiapas, México), y las muestras se trasladaron al laboratorio para su procesamiento posterior. Se usaron tres fijadores diferentes: a) FAA (for- malina, ácido acético, etanol al 70%; 5:5:90); b) glutaraldehido al 5% en amortiguador de fosfatos pH 6.8 con sacarosa al 0.25 M; c) glutar- aldehido al 5% + paraformaldehido al 4% en amor- tiguador de S colidina 0.1 I Después de la fijación algunas muestras fueron deshidratadas en series graduales de alcohol etilico !

El androceo està formado por tres anteras (una flor entre cincuenta y cuatro observadas poseia cuatro anteras). Las anteras son biloculares, y la pared de la antera inmadura está formada por tres capas: la epidermis, el endotecio, y el tapetum (Fig. 2). El tapetum desaparece en la antera madura (Figs. 3, 4).

El gineceo es apocárpico. La ori- entación de los carpelos es variable, de tal manera que la mayoria de ellos no tiene el estilo en el lado orientado hacia los estambres, en el centro del receptáculo. El estilo parte de la región superior del carpelo en el mismo lado que corresponde al hilo de la semilla (Fig. 8). Cada carpelo contiene un solo óvulo sésil, basal, anátropo (Fig. 7), y bitégmico; ambos tegumentos son biestratificados, y el interno forma el micrópilo. El desarrollo del endospermo es de tipo nuclear, y el endospermo maduro posee células de paredes gruesas (Fig. 9). El embrión más desarrollado que se ha observado posee dos células; el cigoto se dividió transversalmente (Fig. La cubierta seminal tiene una capa con inclusiones en forma de partículas. El fruto es indehiscente. La epidermis del fruto posee células globosas cuando está en antesis. DISCUSION Las estructuras reproductoras de Lacandonia schismatica son comparables a las mencionadas por Tomlinson (1982) y por Maas y Rübsamen 1986) para la familia Triuridaceae. La dehiscencia introrsa de las anteras es una caracteristica que define esta especie. Sin embargo, — el hecho más conspicuo, y nunca antes mencionado para Triuridaceae u otras angiospermas, es la posi- ción central del androceo con respecto al gineceo (Cronquist, 1981). Esta disposición se observa más claramente en cortes medianos de botones florales inmaduros La continuidad celular, en especial la epidér- mica, que se observa con los tejidos del centro del receptáculo es la prueba más fehaciente de su posicion. Sin embargo muchos detalles de la for- mación del óvulo y la semilla se desconocen y aun no se sabe que tipo de embrión representan. La germinación no ha sido observada. Se pone de manifiesto la necesidad de realizar estudios em- briológicos, además de estudios anatómicos com- parativos de especies de la familia Triuridaceae. Tales resultados contribuirán a ubicar filogenéti- camente a esta familia y dar luz sobre el Pap d evolutivo de la inversión en la posición de los ór ganos reproductores.

Lacandoniaceae comparte con Triuridaceae los siguientes caracteres: gineceo apocárpico, óvulos anátropos, polen inaperturado, flores trímeras, té- palos con apéndices, hábito saprofítico, y micorri- zas endotróficas. Sin embargo, difiere por: a) La disposición espacial de los órganos reproductores, con los estambres ocupando la parte central de la flor. Tal posición no habia sido contemplada antes para angiospermas (A. P. de Candolle, 1813; Hutchinson, 1959; Takhtajan, 1969; Cronquist, 1981). b) La dehiscencia introrsa de las anteras, extrorsa en Triuridaceae (Tomlinson, 1982; Maas & Rübsamen, 1986). El análisis cromatográfico comparativo entre Triuris sp. y Lacandonia schismatica indica cla- ras diferencias en el tipo de metabolitos secundarios elgado, inéd.). Cronquist (1981) colocó en el orden Triuridales a las familias Petrosaviaceae Hutchinson y Triuri- daceae Gardner. Petrosaviaceae comparte con La- candoniaceae la dehiscencia introrsa de las anteras, el hábito herbáceo, y la micotrofia, pero difiere por presentar estomas, tépalos en dos series, car- — pelos fusionados basalmente con muchos óvulos, nectarios septales, y granos de polen monosulcados. Dahlgren et al. (1985) consideraron en Triuri- dales únicamente a Triuridaceae. La relación espacial que presentan los órganos reproductores es difícil de explicar a la luz de los conocimientos actuales. En ausencia de informa- ción previa, se están llevando a cabo estudios anató- micos (Márquez-Guzmán et al., este tomo) y fito- químicos que ayuden a esclarecer su posición taxonómica. El nombre genérico está dedicado a la región Lacandona, asiento del pueblo Lacandón, en el estado de Chiapas, México.

SYSTEMATICS OF THE AMAZON LILIES, EUCHARIS AND CALIPHRURIA (AMARYLLIDACEAE) Alan W. Meerow?

Heterocharis to the rest of Eucharis, the high levels of al si within the cladogram, and ambiguity caused by missing character state data, a less parsimonious phylogeny is accepted as the basis for classification. Keys and descriptions are provided for all species of Eucharis and Caliphruria. Eucharis caucana, a novel hexaploid (2n — 138) species, is described from Colombia. The closely related genera Eucharis Planchon & Linden and Caliphruria Herbert (Amaryllida- ceae), the Amazon lilies, comprise respectively 17 and 4 species of bulbous, rain forest geophytes adapted to the low light conditions of the forest understory. Together with the Peruvian endemic Urceolina Reichenb., nom. cons., Eucharis and Caliphruria form a monophyletic group delimited by petiolate leaves with distinctive cuticular stria- tion; a turgid seed with a lustrous, usually black testa; and complete fidelity to the rain forest under- story niche. The species are distributed from Gua- temala to Bolivia. The major center of distribution for Eucharis is in the western Amazon basin (in- clusive of major tributary systems, e.g., the Napo, Pastaza, and Huallaga) and the adjoining lower slopes of the eastern Andean cordillera. With the exception of single Peruvian species, Caliphruria is restricted to the Cordillera Occidental and Cor- dillera Central of Colombia. The species of both genera are nowhere abundant, and are found grow- ing only in primary, rarely secondary, forest from !

Large-scale deforestation has proven catastrophic to these plants, which are un- able to adapt to the higher light intensity of the clearings and soon perish. At least several species are probably extinct, and this number will only increase with time as rain forest destruction con- tinues unabated. The Amazon lilies are marked by their ever- green, petiolate leaves; white, often pendent, some- times fragrant flowers with a frequently conspic- uous staminal cup or false corona formed by the basal connation of the staminal filaments; obtusely trilobed stigma; and large, turgid, globose or ellip- soid seeds with a black, brown, or metallic blue testa. Eucharis amazonica Linden ex Planchon is widely known in horticulture, often erroneously as E. grandiflora Planchon & Linden (Meerow & Dehgan, 1984a). Neither genus has ever been crit- ically treated in the taxonomic literature. Baker (1888) provided a key and descriptions for all species known at the time in his Handbook of the Amaryllideae, and Macbride (1936) treated the known Peruvian species of Eucharis for the Flora of Peru. Though species of Eucharis have contin- ued to be described well into the present decade, the delimitation of these species from previously described taxa has consistently remained vague. No assessments of variation at either the population or species level have been attempted. As two of only three genera of neotropical Ama- ryllidaceae (the other being the related Urceolina) exhibiting complete fidelity to a primary rain forest niche, systematic understanding of Eucharis and Caliphruria offers important information relating to the evolution of the pancratioid Amaryllidaceae (“infrafamily Pancratioidinae" Traub (1957, 1963)),* centered in the central Andean region of South America. No taxonomic scheme can encompass all of the information about the group of organisms under study (Holsinger, 1984, 1985; Ornduff, 1969; Ra- ven, 1 . In genera such as Eucharis and Cal- iphruria, rare in the wild and often accessible only with difficulty, and which often exhibit cryptic pat- terns of variation, this observation becomes much more acute. By accumulating data from as many diverse sources as possible, I have attempted to construct an evolutionary systematic classification of the Amazon lilies that is both practical yet re- flects their evolutionary relationships as accurately as these data allow. MATERIALS AND METHODS FIELD STUDIES Fieldwork was conducted in Peru and Ecuador in July-August 1982, and in Colombia and Ec- uador in July-August 1984. Herbarium specimens and living material were collected, and ecological observations of natural populations were made. ANATOMICAL STUDIES AND SCANNING ELECTRON MICROSCOPY (SEM) Material was prepared and examined as de- scribed in Meerow (1987c) CLADISTIC ANALYSES Cladistic analyses were run using PAUP version 2.4.1 by David L. Swofford (Illinois Natural History Survey). All species (and two subspecies) of Fu- charis and Caliphruria (22 evolutionary units, EUs) excluding hybrid taxa were analyzed using forty-one characters (Tables 1—3). For analyses with PAUP, global branch swapping with the MUL- PARS option was used in all dep for the most parsimonious cladograms. Because of the unavail- ability of material, all desc n. species of Urceo- lina could not be included in the analysis. Urceo- lina was therefore entered in the analysis at the generic level, with character state data drawn from study of living material of U. microcrater Krànzlin and specimens of U. urceolata (Ruiz & Pavón) Green and U. ayacucensis Ravenna. Character states were determined from examination of living and dried material. Character state polarities were assessed via outgroup comparison (Maddison et al., 1984; Watrous & Wheeler, 1981). Selection of outgroups is discussed later with the results of the analyses Of ihe 41 characters used in the analysis, 23 were simple, two-state characters. The 18 remain- ing multistate characters (14 three-state, 2 four- state, | five-state, and 1 six-state) were treated in preliminary analyses as unordered (Fitch, 1971; Hartigan, 1973) using this option of PAUP, rather than attempting to create any a priori transfor- mation series. This resulted in a preponderance of weak monophyletic groups based on single apo- morphies and/or character state reversals, as well as unresolved polytomies among many terminal taxa. In the analyses presented, 11 of these char- acters were treated as ordered transformation se- ries (the remaining seven as unordered), with one * This unofficial rank is used in this paper as a label of convenience, since there is as yet insufficient evidence to ly. recognize this group of genera as a distinct subfami 138 Annals of the Missouri Botanical Garden (number 41, chromosome number) coded in ad- ditive binary. Justification for these treatments is discussed with the results of the analyses. Multistate characters were adjusted to equal weight with two- state characters using the "weights scale" option of PAUP. Additionally, an alternative hypothesis of generic relationship was tested by submitting a user-coded tree topology to PAUP for analysis. HERBARIUM STUDY AND LIVING MATERIAL Loans or gifts of herbarium specimens were re- ceived from the following herbaria: AAU, B, BM, COL, CUVC, F, FTG, G, GB, GH, GOET, HUNT, K, LE, M, MG, MICH, MO, MPU, NA, NY, OXF, P, QCA, S, SEL, SP, U, UC, US, VEN. Neither Eucharis nor Caliphruria is well rep- resented in herbarium collections, and critical mor- phological characters are often obscured by the drying process. Consequently, a living collection of over 100 accessions representing fifteen species and several hybrids was accumulated from botan- ical gardens, individuals, and field collections by myself and various colleagues. Vouchers for living material are listed with specimens cited for each species. TAXONOMIC HISTORY Herbert (1844) described the new genus Cali- phruria from collections made in New Granada (Colombia) near Guaduas by Hartweg, placing Cal- iphruria in the “section” Pancratiformes of ““sub- united by the single character of staminal conna- tion. The small, white, funnelform flowers were marked by the presence of a bristle or slender tooth at either side of the filament. Herbert (1844) made no mention of basal connation of the filaments. The orthography of the name, a single "I" in the Greek stem *'calli-," was emended by subsequent workers (e.g., Baker, 1877), but was returned to Herbert's original by Meerow & Dehgan (1984b). Planchon & Linden (1852) introduced another new pancratioid genus, Eucharis. The first species described, E. candida Planchon € Linden, col- lected in New Granada by M. Schlim, was char- acterized by its crateriform flowers with a con- spicuous staminal cup and a widely spreading perianth limb. If these authors were aware of Cal- iphruria, they did not note any relationship be- tween it and Eucharis. Bentham & Hooker (1883) placed Caliphruria and Eucharis in the tribe Cyathiferae. Caliphru- ria subedentata Baker was combined with Eucha- ris in their treatment, while C. hartwegiana Herb. was retained. Baker (1888) accepted this treat- ment, yet described another new species as C. tenera. He described Caliphruria as "nearly allied to Eucharis.” Baillon (1894) described the species C. castel- naeana and declared it precisely intermediate be- tween Caliphruria and Eucharis. He further sug- gested that Eucharis should be treated as a section of Caliphruria. Macbride (1931) later transferred C. castelnaeana to Eucharis. Nicholson (1884) transferred C. hartwegiana (the type species of Caliphruria) to Eucharis, ignoring the former's nomenclatural priority. Traub (1967) made the formal transfer of the remaining species of Caliphruria, C. tenera Baker, to Fu- charis and combined the monotypic genus Pla- giolirion Baker with Eucharis. He had previously listed Caliphruria, Plagiolirion, and Mathieua Klotzsch (another monotypic genus) as synonyms for Eucharis in his Genera of the Amaryllidaceae, citing Baillon (1894) as a “special reference" (Traub, 1963: 74). The nomenclatural priority of Caliphruria Herbert was overlooked. No proposal for the conservation of Eucharis Planchon & Lin- den over Caliphruria Herbert has ever been pro- posed previous to that of Meerow & Dehgan Traub (1971) later combined Eucharis with Ur- ceolina, a small Andean genus with petiolate leaves and markedly urceolate, brightly colored flowers. He designated five subgenera: Urceolina, Eucha- ris, Caliphruria, Mathieua, and Plagiolirion. Traub (1971) offered no explanation for the com- bination of Eucharis and Urceolina, but presum- ably his decision was prompted in part by reports in the literature of two intergeneric hybrids between Eucharis and Urceolina: x Urceocharis clibranii Masters, an artificial hybrid, and x U. edentata C. H. Wright, putatively discovered in Peru. Plagi- olirion and Mathieua are monotypic genera allied to Hymenocallis Salisb. and Stenomesson Herbert respectively (Meerow, 19872). VEGETATIVE MORPHOLOGY BULBS The globose or subglobose bulbs of Eucharis and Caliphruria, composed of concentric and modified leaf bases (scales), are characteristic of most members of the Amaryllidaceae. The bulbs are sympodial in growth habit (Arroyo, 1984). The outer scales of Kucharis and Caliphruria bulbs are modified into an either brown or tan paper tunic.

Distally, the pseudostem grades into the petiole of individual leaves. The neck of Eucharis and Caliphruria bulbs always remains below the soil surface. Length of the neck may therefore be more a factor of bulb depth in the substrate rather than of any phylo- genetic pd Bulbs of most species of Eu- charis Caliphruria offset regularly and vig- 4 Me forming sizable clumps in time i undisturbed. LEAVES Leaves of Eucharis and Caliphruria are uni- formly long-petiolate, with a well-developed elliptic, ovate, or lanceolate lamina. Petiolate leaves are characteristic of a number of genera of Amaryl- lidaceae, either completely or in part, and have undoubtedly evolved independently several times from the linear or lorate leaf morphology typical of the family. The petiole of the leaf of Eucharis and Cali- phruria is usually as long or longer than the lamina. 140 Annals of the Missouri Botanical Garden It tends toward subterete cross sections (Fig. 1), rounded abaxially, and flattened adaxially, becom- ing slightly channeled proximal to the sinus. The petiole is winged proximal to the sinus by atten- uation of the lamina. The midrib is pronounced abaxially along the entire length of the lamina, and slightly channeled adaxially, continuous with the petiole. Leaf shape only rarely provides taxonomically useful information. Length / width ratios are subject to considerable variation even among the leaves of a single bulb. Herbarium specimens will frequently include only a single leaf, with no indication of its developmental age. Taxonomic consistency of leaf shape is exceptional, but useful in the few cases where it occurs. For example, leaves of E. ulei Kranzlin are consistently narrowly elliptic. Eucha- ris amazonica (leaf length / width ratio greater than 2) may be delimited from E. moorei (Baker) Mee- row (1/w less than 2). The leaves of Eucharis and Caliphruria are completely glabrous and nonglaucous, with a single exception. Eucharis bonplandii (Kunth) Traub, a rare tetraploid species from central Colombia, de- velops a glaucous bloom that gives the leaf a blue cast in strong light. The leaf apex of all species is shortly acuminate, the base attenuate. Coarse undulation of the margin will sometimes make the lamina appear cordate at the base. Leaf margins of Caliphruria are uni- formly nonundulate. Leaf venation of Eucharis and Caliphruria is parallelodromous (Hickey, 1973), with a great number of transverse, commissural veins intercon- necting the primary vasculature. All species of Caliphruria have smooth, nonplicate leaves. Eu- charis is variable for this character, but the ma- jority of species have plicate leaves. The adaxial epidermis of most species of both genera is lustrous, dark green; the abaxial surface appears lighter, or silvery green. Only E. astro- phiala (Ravenna) Ravenna has diverged markedly from the typical morphology and has a uniquely nonlustrous, bullate-pustulate leaf texture. CUTICLE Cuticular striation is prominent on the abaxial leaf surfaces of most Eucharis and Caliphruria species (Figs. 2-6, 8-12). Striae are thickest in C. subedentata (Fig. 11). Arroyo & Cutler (1984) recognized eight cuticular sculpturing classes in a survey of 25 genera of Amaryllidaceae. The most common cuticular morphology of Kucharis and Caliphruria fits their class VII: "thick striae, par- allel or not, interlocking, + transverse.' In a few species of Eucharis (E. amazonica, E. moorei (Fig. 10), E. bouchei (Fig. 9)), the striation is much less pronounced. Caliphruria kor- sakoffii (Traub) Meerow (the sole representative of Caliphruria outside Colombia) has the most aberrant cuticle morphology (Fig. 12), correspond- ing more or less to type V of Arroyo & Cutler (1984): *central, thick axial striation with less pro- nounced striae running from it, directly to anticlinal walls." The adaxial cuticles of Eucharis and Cal- iphruria are either smooth or rarely much more finely striate than the abaxial surface, the striations entirely axial in orientation. The adaxial cuticle of C. korsakoffii (Fig. 13) has several, thick, trans- verse striations across each cell, and the epidermis is unusually flat. STOMATA Leaves of Eucharis and Caliphruria are pre- dominantly hypostomatic. Stomata occur adaxially only along the midrib and vicinity (Fig. 14A), and occasionally in the proximity of primary veins. Stomata are usually absent from the abaxial midrib (Fig. 14B). Intercalary stomata were regularly ob- served only in E. cyaneosperma Meerow (Figs. 7, 15D). The stomata of Eucharis and Caliphruria are anomocytic, as is typical for Amaryllidaceae (Arroyo & Cutler, 1984; Dahlgren & Clifford, 1982), though E. astrophiala exhibits at least slight differentiation of cells neighboring the sto- mata (Figs. 2, 3) from other epidermal cells. These cells are more densely and regularly striate than other epidermal cells, as well as slightly more raised. The guard cells of Fucharis and Caliphruria are oriented with their longest axis parallel to that of the leaf. EPIDERMAL CELLS Abaxial epidermal cells range from rectangular to irregular in shape. Adaxial epidermal cells are in almost all cases rectangular. Kucharis astro- phiala (Fig. 15A) has the most irregularly shaped cells of both the abaxial and adaxial surfaces. In the vicinity of the midrib on both surfaces of the leaf (Fig. 14), epidermal cells become conspicu- ously elongated, and anticlinal walls are straight. Epidermal cells of the midrib are extremely long and narrow. The epidermal cells of all species of Eucharis subg. Eucharis have strongly undulate anticlinal walls (Fig. 15), as noted by Asatrian (1984) for the few species he surveyed. End walls of both the abaxial and adaxial cells of all species range from oblique to rounded. Abaxial cells are more strongly Volume 76, Number 1 Meerow 141 1989 Eucharis and Caliphruria FiGURES 2-7.

Epidermal cells of Caliphruria (Fig. 15F) are more weakly undulate than those of Eucharis. The anticlinal walls of adaxial cells of C. korsakoffii are com- pletely straight. Eucharis subg. Heterocharis is polymorphic for anticlinal wall morphology. Ku- charis amazonica and E. sanderi have strongly undulate walls, while E. moorei (Fig. 15E) has essentially straight walls. LEAF ANATOMY In petiolar transverse section, a single arc of vascular bundles is usually observed (Fig. 1). Me- dian bundles are the largest. In petioles of E. moorei (Fig. 1E) and the closely related E. amazonica (Fig. 1F), both in subg. Heterocharis, small sec- ondary bundles were observed near the adaxial surface. These bundles are most conspicuous in £F. moorei; they are markedly smaller in E. amazon- ica. These secondary vascular traces disappear above the middle of the petiole. Asatrian (1984), who reported on petiole anatomy of three Eucharis and Caliphruria species, did not observe these bundles in E. amazonica (cited as E. grandiflora). The internal morphology of leaves of Eucharis and Caliphruria (Figs. 16-22) is largely invariant across both genera. No well-defined palisade layer is evident, the absence of which is characteristic of most genera of "infrafamily" Pancratioidinae (Arroyo & Cutler, 1984). Mucilage cells, common throughout the family (Arroyo & Cutler, 1984), are often present near the leaf surface, and ra- phides are occasionally observed in epidermal cells. The mesophyll consists of several layers of chlo- renchyma both ad- and abaxially, and a thicker region of spongy, slightly aerenchymous tissue. Small air cavities occur regularly only directly be- low stomata. Vascular bundles are surrounded by a sheath of one or two layer(s) of parenchymous cells. The only xylem elements present are tra- cheids with annular thickenings (Fig. 19). FLORAL MoRPHOLOGY INFLORESCENCE The inflorescence of Eucharis and Caliphruria is a naked scape typical of Amaryllidaceae. The scape is subterete in cross section and has a solid pith. Vascular bundles are distributed in several irregular, concentric rings within the pith. A layer of collenchyma cells occurs just below the epider- mis. The scape is terminated by two valvate-imbri- cate, ovate-lanceolate bracts that enclose several iS FIGURE 14.

Heterocharis) to greenish white (most species of subg. Eucharis) and are soon marcescent after opening and spreading laterally. Each flower is subtended by a linear-lanceolate bracteole. The inflorescence of the Amaryllidaceae is tra- ditionally described as **umbellate." Mann (1959) and Stout (1944) demonstrated that the superfi- cially simple umbel of Amaryllidaceae actually rep- resents a complex series of reduced, helicoid cymes. Anthesis occurs in a strict sequence within each cyme from the developmentally oldest flower to the youngest. The peripheral cymes flower first; the central cymes flower last. Flower number varies in Eucharis and Cali- phruria from 2 to 10, rarely as many as 12 (C. korsakoffii, rarely in E. castelnaeana). Number of flowers is often a taxonomically useful character, though any species characterized by 8-10 flowers is capable of producing a depauperate inflorescence with fewer florets. An increase in flower number 144 Annals of the Missouri Botanical Garden GAS UA Vero RAS EY ISA ee IR a RA PESOS pi Y DAT FIGURE 15A-C. Leaf epidermal configurations of representative Eucharis and Caliphruria species in the inter- costal area of the leaf. — A. E. E. castelnaeana (Schunke 14156, FLAS). generally does not occur. In some species of subg. Eucharis (E. astrophiala, E. bouchei, E. ulei), a flower number of five has become virtually fixed. Reduction in flower number is usually considered the derived state in Amaryllidaceae (Traub, 1962, 1963). FLOWER SIZE The largest flowers in Eucharis are found in subg. Heterocharis, where they average 7-8 cm in length. Flowers of Caliphruria are the smallest, never exceeding 4 cm long. Subgenus Eucharis, the largest of the two subgenera of Eucharis, is astrophiala (Madison 3792, SEL).— B. E. bonplandii (Bauml 686, HUNT).—C. variable, with flowers 3-7 cm in length. Within a fairly broad range, flower size can be used to dis- tinguish phenetic species complexes within subg. Eucharis; however, most species of this subgenus are quite variable in size (Meerow, 1987 d, in press). FLORAL FRAGRANCE Subgenus Heterocharis is the only subgenus of Eucharis with uniformly fragrant flowers. The fra- grance of all species of subg. Heterocharis is in- tense and sweet. Flowers of Caliphruria do not emit any detectable fragrance. Most species of Eucharis subg. Eucharis also lack noticeable fra- Volume 76, Number 1 1989 Meerow Eucharis and Caliphruria 145 FicuRE 15D-F.

Brown, E. castelnaeana (Bail- lon) Macbr., E. formosa Meerow, and E. plicata Meerow subsp. brevidentata Meerow), the odor is not intense. In £. formosa the odor is slightly fetid. PERIANTH The perianth of Eucharis and Caliphruria con- sists of six tepals in two whorls, basally connate into a tube of varying length and morphology. The tube of Eucharis subg. Eucharis (Fig. 23E) is cylindrical for almost its entire length, abruptly dilating near the perianth throat. The tube of subg. Eucharis is also strongly curved, either abruptly just above the ovary (E. bakeriana, E. cyaneo- sperma) or gradually throughout the proximal half of its length (all other species). The curving of the tube results in the pendent habit of most species of subg. Eucharis. The tube is white for its entire length. The tube of subg. Heterocharis (Fig. 23C, D) is tinted green proximally (for as much as half its length). The tube is curved, though not as markedly 146 Annals of the Missouri Botanical Garden FicuRES 16-22.

The tube is tinted green proximally (in C. subedentata, for V$—75 of its length). The tepals of Eucharis and Caliphruria flowers are white. Those of the outer series are almost always longer and narrower than the inner tepals. The outer tepals are apiculate. The apiculum fre- quently has a small, papillate horn on the adaxial surface in Eucharis subg. Eucharis. The inner tepals vary from acute to obtuse, sometimes mi- nutely apiculate, at the apex. e tepals of most species of subg. Eucharis spread at an angle of 90? or more from the throat. Perianth morphology of subg. Eucharis is thus predominantly crateriform. At times the tepals may be reflexed strongly above the midpoint of their length, or rarely for their entire length. Tepal habit varies even among flowers of the same inflores- cence and shows no taxonomic consistency. If ex- posed to strong light, the abaxial midrib of the tepals of some species of subg. Eucharis may be lightly pigmented yellow. The perianth of Caliphruria is infundibular. The tepals remain imbricate for half their length and spread distally at angles of only 45-60”. The tepals of subg. Heterocharis are also for the most part imbricate proximally and spread at 45-60? from the throat. The perianth is more or less campan- X Calicharis butcheri (Meerow 1110, FLAS). — E. E. astrophiala (Madison 3792, SEL). —C. E. sanderi (Cuatrecasas 16380, ulate. One species, E. amazonica, has the crater- iform perianth characteristic of A Eucharis with a wide-spreading (ca. 90?) limb ANDROECIUM The stamens of Eucharis and Caliphruria are variously connate proximally. In all but three species of Eucharis, a conspicuous staminal cup is present (Figs. 24, 25). In Caliphruria, the cup is reduced to a short, membranous, connate portion of the filaments near the perianth throat (Fig. 26). Fu- charis sanderi (subg. Heterocharis) has a reduced staminal cup similar to that of Caliphruria. Stam- inal connation is one of the major characteristics of *'infrafamily" workers considered the staminal cup of pancratioid genera homologous to the corona of Narcissus L. (e.g., Pax, 1888). The corona of Narcissus is generally considered to be of perianthal origin (Eichler, 1875; Arber, 1937), while the staminal cup of pancratioid taxa has been described as com- posed entirely of androecial tissue (Arber, 1937; Singh, 1972). Einsiedel (1987) and Müller-Doblies (pers. comm.) consider this distinction artificial and claim that both structures arise from the same meristematic potential, citing putative instances of polymorphy for both types within the same genus. Stamens of Eucharis and Caliphruria may be dentate, edentate, or irregularly toothed. Both types of staminal morphology may occur in the same species, and variation may occur even among flow- Pancratioidinae.

The presence or absence of staminal dentation has frequently been overweighted in the alpha-taxonomic litera- ture relating to these genera (e.g., Ravenna, but can still be of taxonomic significance (e.g., E. astrophiala (Fig. 24), the only species of subg. Eucharis that always has an edentate staminal cup). A variable pattern of green or yellow pigmen- tation is present in the androecium of all species of subg. Eucharis and Heterocharis. Stamens of - No) eo Caliphruria are completely white. In subg. Het- erocharis, the green (rarely yellowish) pigmenta- tion is largely restricted to the interior of the cup, and extends into the dilated portion of the tube as well (Fig. 25). The coloration is concentrated along the filamental traces, but the tissue between the traces is also suffused with green. In subg. Kucha- ris, pigmentation is present on both the exterior and interior surfaces of the cup, does not extend into the dilated portion of the tube, and takes the form of either broad spots below each free filament or a uniform band of color at the basal V$- V4 of the cup. In this subgenus, the pattern is of limited taxonomic significance. Whether the pigmentation functions as nectar guides for pollinating animals is unknown. The stamens of most species of subg. Eucharis constrict distally into a broadly subulate portion (greater than 1 mm wide for most of its length) of varying length. Only in E. astrophiala (Fig. 24) and E. bouchei (in part) do the stamens constrict gradually from the rim of the staminal cup to the apex of the filament. The free filaments of Cali- phruria are narrowly subulate (less than 1 mm wide for most of their length, Fig. 26). The free filaments of E. sanderi (subg. Heterocharis) are narrowly subulate and slightly incurved. Those of E. moorei and E. amazonica are broadly subulate. Anthers of Eucharis are introrse, dehiscing lon- gitudinally, and either dorsifixed or sub-basifixed. They are most frequently oblong but are linear in subg. Heterocharis. At anthesis, the anthers of Caliphruria and Eucharis subg. Eucharis are erect but become versatile as they age. In subg. Het- erocharis, the anthers are versatile at anthesis. STIGMA AND STYLE Of the sixteen species of Kucharis and Cali- phruria observed in cultivation, all but Æ. castel- naeana are protandrous. Stigma receptivity does not occur until the second or third day following anther dehiscence. In some cases, the stigma does not fully expand until the perianth has begun to senesce. Successful greenhouse pollinations have been accomplished after the onset of periant nescence. In the single known autogamous species, E. castelnaeana, stigma receptivity and anther dehiscence coincide The styles of Eucharis and Caliphruria are usually exserted beyond the anthers, most fre- FIGURES 27-39. 1111, FLAS).—29.

Trilobed stigmas are relatively rare in the Pancratioidinae, and Urceolina—sister group to Eucharis and Cal. iphruria—has a capitate, entire stigma. Traub (1963) and Traub & Moldenke (1949) considered a trilobed or trifid stigma the ancestral state in the Amaryllidaceae. Volume 76, Number 1 1989 Meerow 151 Eucharis and Caliphruria The stigmatic papillae of Eucharis are unicel- lular (Figs. 28, 34-37), while those of Caliphruria (Fig. 31) are multicellular, consisting of both a stalk cell and globose head cell. x Calicharis butcheri, putatively a natural hybrid of E. sanderi and C. subedentata, has the multicellular stigmatic papillae (Figs. 38, 39) characteristic of Caliphru- ria. Heslop-Harrison & Shivanna (1977) charac- terized the stigmas of Eucharis and Caliphruria as dry-type. OVARY AND OVULES The ovary of Eucharis and Caliphruria is in- ferior and contains septal nectaries. It is green, with the exception of two species, E. astrophiala and E. castelnaeana (subg. Eucharis), in which the ovary is white at anthesis. Ovaries of Eucharis and Caliphruria range from oblong-ellipsoid (subg. Heterocharis) to globose or subglobose (Caliphru- ria and Eucharis subg. Eucharis). The ovary of subg. Heterocharis appears rostellate after senes- cence of the perianth. The ovules of Eucharis and Caliphruria are globose, anatropous, and borne on axile placentae. Ovule number is quite variable throughout both genera. Within limits, however, this number is characteristic of species or species complexes. Sub- genus Heterocharis has the largest ovule number in Eucharis, generally 16-20 per locule, but oc- casionally as low as 7 in E. sanderi (which oth- erwise has 16-20 throughout most of its range) and 9-12 in E. amazonica. In both Caliphruria and Eucharis subg. Eucharis, ovules do not num- ber more than ten per locule. Eucharis astrophi- ala, E. bouchei, E. bonplandii, E. cyaneosperma, and E. ulei characteristically have two ovules per locule, but rarely as many as five. FRUIT The mature fruit of Eucharis and Caliphruria is a triloculicidal capsule typical of the nonbaccate- fruited Amaryllidaceae. In fruit, the pedicel elon- gates to two or more times its length at anthesis. In Caliphruria and Eucharis subg. Heterocharis (E. moorei), the capsule is thin-walled and green, sometimes turning yellow or brown at dehiscence. In subg. Eucharis, however, the capsule is leathery and bright orange (Fig. 40), contrasting vividly with the shiny black or blue seeds at dehiscence. It is probable, though unsubstantiated, that the combination of fruit and seed color functions mi- metically to attract avian dispersal agents (sensu van der Pijl, 1982). In the single known exception to this characteristic fruit morphology in subg. Eucharis, the fruit of E. castelnaeana (Fig. 41) remains green until shortly before dehiscence, at which time it yellows and finally turns brown. It is often tardily dehiscent and sometimes abscises be- fore opening, though the seeds within are ripe. SEED Regardless of the number of ovules per locule in any species of Eucharis and Caliphruria, all but a few abort as the fruit matures. Generally one to three seeds are present per locule in mature capsules, but as many as four have been observed (Fig. 40) The seeds of both Eucharis and Caliphruria are globose or ellipsoid and turgid, the consequence of copious, oily endosperm and a high moisture content. Left at room temperature, the seeds will shrink away from the testa somewhat as moisture is lost but remain capable of germination. Long- term viability has not been tested. The seed of subg. Eucharis (Fig. 42) is char- acteristically ellipsoid and has a shiny, smooth black (blue in E. cyaneosperma) testa. The single ex- ception so far known is again E. castelnaeana (Fig. 43). The seed of this species is wedge-shaped by compression in the capsule, is less turgid than seeds of consubgeneric species, and has a dull, rugose testa. The seed of E. moorei (subg. Heterocharis) is globose to very slightly compressed and has a brown, slightly rugose testa. In Caliphruria, the seeds of only C. korsakoffi and C. subedentata are known. Seeds of C. kor- sakoffii are globose, turgid, and have a smooth, lustrous brown testa. Seed of C. subedentata is slightly compressed, with a lustrous black but ru- gose testa. The testa is alveolate in all species examined (Figs. 44-49). In E. bouchei var. dressleri Mee- row (Fig. 45), abundant wax extrusions are found Caliphruria seeds is composed of phytomelan (Huber, 1969), a simple, largely inert, carbona- ceous compound characteristically present in the seed coat of nonbaccate-fruited Amaryllidaceae (Dahlgren & Clifford, 1982; Huber, 1969). Wer- ker & Fahn (1975) reported the occurrence of phenolic quinones in the phytomelan layer of Pan- cratium seeds. In most species of Eucharis and Caliphruria, the phytomelan layer is all that re- mains of the integuments (Figs. 51, 57). In £. bouchei, however, there is an additional layer of integument tissue about five cells thick, interposed between the phytomelan and the endosperm (Fig. 55).

These important seed differences have been overlooked by most phylogenists of the Amaryllidaceae. The turgid seed of Kucharis and Caliphruria, despite a high moisture content when first ripe, cannot be accurately described as fleshy. This be- comes evident if the seed is allowed to dehydrate slightly at room temperature, and is most apparent in the hard seeds of E. castelnaeana, which, at capsule dehiscence, are less turgid than seeds of other species of subg. Kucharis. Seeds of Eucharis and Caliphruria have a reduced integument, rep- resented in most cases only by the compressed phytomelan layer, and have never been observed to germinate viviparously. Phytomelan is absent from the testa of the pseudoseeds of Kurycles and Calostemma. It is present in only a single species of Hymenocallis, H. quitoensis Herbert (and prob- ably its close relative H. heliantha Ravenna), which has been segregated into the separate genus Lep- idochiton Sealy (1937) on this basis. Seeds of Pancratium are structurally most sim- ilar to those of Eucharis and Caliphruria. Al- though variable in shape and surface features (Werker & Fahn, 1975), all species of Pancratium have a hard, turgid, ovoid or compressed seed body with copious endosperm (Meerow, unpubl. data; Werker & Fahn, 1975). All examined species of Pancratium have a phytomelanous and alveolate testa. Seeds of Eucharis and Caliphruria have a higher moisture content than those of Pancratium, all species of which occur in xeric to seasonally dry habitats. POLLEN MORPHOLOGY Pollen morphology of Eucharis and Caliphruria is reviewed in detail elsewhere (Meerow & Deghan, 1988) and will only be summarized here. Pollen grains of all species of Eucharis and Caliphruria (Figs. 59-62) are boat-shaped elliptic, monosul- cate, heteropolar, and bilaterally symmetrical. The sulcus runs the length of the distal face of the grain. Exine sculpturing is semitectate/reticulate in all species examined. Pollen of most Eucharis falls into Walker & Doyle's (1975) large size class (longest equatorial diameter 50-100 um). A single species, E. cau- cana, has very large pollen (longest equatorial di- ameter as much as 110 um). Pollen of Eucharis has average longest equatorial diameters greater than 60 um, with two exceptions: E. castelnaeana and E. plicata subsp. brevidentata, the two small- est-flowered species. Most species of Eucharis have pollen grains with longest equatorial diameters be- teen 65 and 75 um. Pollen of Caliphruria falls into the medium size class of Walker & Doyle (1975), with average longest equatorial diameters near 50 um. Polar diameter of pollen of most Eucharis species ranges from 45 to 60.6 um— diameters less than 40 um are rare. Polar diameter of pollen of Caliphruria is always less than 40 um. Exine reticulation of Eucharis is character- istically coarse (Figs. 59-61), while that of Cali- phruria is fine (Fig. 62). CHROMOSOME CYTOLOGY A somatic chromosome number of 2n = 46 largely characterizes both genera (Meerow, 1987b). Two tetraploid species (2n = 92), E. bonplandii from Colombia and E. bouchei from Central Amer- ica, are known. Eucharis caucana, described in this paper from Colombia, is a hexaploid with the largest chromosome number in the genus (2n — 138). Eucharis amazonica, 2n — 68, is the only known departure from these 2x, 4x, or 6x karyo- types. À somatic chromosome number of 2n — 46 (or derivations thereof) is characteristic of most genera of neotropical Pancratioidinae (Di Fulvio, 1973; Flory, 1977; Meerow, 1987b, c; Williams, 1981). EcoLoGY AND PHYTOGEOGRAPHY ECOLOGY All species of Eucharis and Caliphruria exhibit high fidelity to a primary forest habitat, and severe disturbance of the forest canopy is catastrophic to the plants. In recently cleared forest sites, the bulbs persist for a few seasons, but the leaves developed in sunlight show chlorosis and necrosis. Wilkins (pers. comm.) reported that leaves of E. amazonica are damaged at light levels above 5,000 foot can- dles, an observation confirmed by Rees (1985). Fidelity of these genera to mesic, low-light habitats suggests a strongly evolved adaptive complex. Only two other genera of pancratioid Amaryllid are completely adapted to forest understory: Eurycles, a small Australasian genus, and Urceolina, sister group to Eucharis and Caliphruria. Eucharis populations are often largest on flood- plains of small rivers and creeks where frequent short-term inundation is likely. Eucharis is also found in more upland sites, but usually in less abundance. No fully deciduous species of subg. Volume 76, Number 1 1989 Meerow 155 Eucharis and Caliphruria FiGURES 59-62.

Eucharis have been observed, though E. astro- phiala, endemic to the western slopes of north- central Ecuador, enters a season of dormancy when growth ceases. Yet several leaves may persist for the duration. The rarity of Eucharis and Caliphruria species throughout their range is a striking characteristic of their distribution. Single, widely dispersed clumps of bulbs are more the rule than the exception. Herbarium collections are usually unicates and often indicate the relative infrequency with which the plants were encountered in the forest. The largest population of Eucharis that I have observed con- sisted of about 30 individuals of E. moorei in an approximate half-hectare area. Throughout eastern Ecuador, populations of only two or three clonal clumps or single bulbs (and frequently as low as one) of E. candida, E. formosa, and E. moorei are common. In eastern Peru, a careful search through a five-hectare area turned up only two plants of E. cyaneosperma. Edaphic conditions are probably important in limiting colonization and es- tablishment of Eucharis species. Restriction to sites of high fertility is evident for all species of Eucharis and has been noted by floristic workers in the Amazon basin and Chocó region of Colombia (A. Gentry, pers. comm.). No species of Eucharis are found natively above 1,800 m. The overwhelming majority of collections are from elevations below 1,000 m and, of these, more than half are below 500 m. Caliphruria is primarily collected at sites above 1,000 m (“selva- subandina" of Cuatrecasas, 1958). Most collec- tions of Caliphruria (C. subedentata) were from the Río Cauca River valley of western Colombia, an area now largely deforested. In July 1984, 1 was not able to find members of this genus in any of its historical localities. 156 Annals of the Missouri Botanical Garden PHYTOGEOGRAPH Y More than half of the known species of Fucharis subg. Eucharis are found on the eastern slopes of the Andes. The majority of these species are con- centrated along the Amazon and its main tributar- ies, e.g., the Napo and Pastaza system in Ecuador and the Huallaga of Peru. Seven of the fourteen extant species of subg. Eucharis are endemic to the premontane Andean- Amazonas interface, but no species has been reported east of 68°W longi- tude. Thus the genus appears to be absent from the great, largely Brazilian expanse of lowland Amazonas. Five peripheral isolate species from the premontane Andean-Amazonian center of distri- bution show some degree of morphological novelty (see Taxonomic Treatment). Eucharis corynan- dra, very closely related to E. castelnaeana and E. plicata, and E. oxyandra, of uncertain phy- logenetic relationship, are both known only from the “ceja de la selva” forest formations of north- central eastern Peru. Eucharis astrophiala is en- demic to a relatively small area of western Ecuador. Eucharis lehmannii and E. caucana are restricted to western Columbia. Of the five species, only £. astrophiala is known from other than the type locality. Three of the four species of subg. Eucharis that occur above 2°N latitude are polyploids (chromo- some number is unknown for E. lehmannii). Eu- charis bonplandii (2n — 92), endemic to the Cor- illera Oriental and Cordillera Central of Colombia is rare and infrequently collected. The E. bouchei complex (2n — 92), a series of geographically isolat- ed and morphologically distinct population clusters (Meerow, 1987d), is endemic to Central America, chiefly Panama. Eucharis caucana is a hexaploid (2n = 138) Subgenus Heterocharis is widely dispersed from Colombia to Peru, but each of its three species are arrowly distributed. With the exception of a single E. moorei is not Eucharis found on both sides of the Andes. Eu- charis amazonica occurs natively within a narrow area of the Rio Huallaga valley in Peru. Eucharis sanderi is endemic to the Chocó region of Colom- ia. Caliphruria is almost completely western Co- lombian, most prominently in the Rio Cauca valley, with a secondary distribution in the Río Magdalena valley. Caliphruria korsakoffii is Peruvian. ETHNOBOTANY Labels of a number of herbarium specimens of Eucharis species indicate that lowland native peo- ple collect the bulbs for use as poultices. The bulbs are mashed, heated, and applied to sores and tu- mors. Lewis (1986) described the use of mucilage from Eucharis bulbs (the plant illustrated is Æ. formosa) by the Jivaro Indians of Peru for treating facial blemishes and acne. Indian women of the Pastaza valley in Ecuador reportedly quite actively collect the plants in flower for reasons they would not disclose (N. Whitten, pers. comm.). Most local inhabitants whom I met while collecting Eucharis in the Oriente were readily familiar with the plants when shown photographs. That various neotropical Amaryllidaceae have been cultivated in their native countries for many years cannot be discounted. Motifs recognizable as species of Zephryanthes Herbert and Stenomes- son Herbert appear on ceremonial Incan vases (Vargas, 1981). The seasonal mass-blooming of Hymenocallis amancaes (Ruiz & Pavón) Nichols. on the dry hills near Lima, Peru, has long been the nucleus of an annual festival named for that species (Herbert, 1839). I have suggested that frequent sympatric occurrence of E. candida and ; y have been influenced by cultivation by transient agriculturists (Meerow, 1987e). Further circumstantial evidence for this hypothesis is the doen in nature E sterile hybrid taxa such as F. randiflora a X Calicharis butcheri. Almost all collections of i former are remnants of cultivation. Eucharis ox- yandra is known only from bulbs found uprooted by an abandoned dwelling in Peruvian rain forest (see Taxonomic Treatment). E. formosa in eastern Ecuador ma REPRODUCTIVE BIOLOGY PHENOLOGY Eucharis and Caliphruria species are largely seasonal flowering. Very well-collected species, such as E. candida or E. formosa, show flowering pat- terns skewed toward certain months (January to arch), but at least several flowering collections have been made throughout the year. Species in Amazonian Peru have been collected in flower most frequently from June to September. Each inflores- cence is moderately long-lived, two to three weeks, but usually no more than one to three flowers are open at any one time In the greenhouse, observations over a five-year period confirm an annual flowering for most Eu- charis and Caliphruria species. Eucharis ama- zonica, however, flowers two or three times during the year. Van Bragt & Sprenkels (1983) have regularly induced flowering in this species at any time of the year after treatment at 27?C for at least two weeks. Collection data for this species Volume 76, Number 1 1989 Meerow 157 Eucharis and Caliphruria throughout its narrow range indicate that twice- annual phenology may occur in habitat as well. Eucharis castelnaeana mass-flowers in the green- house several times per year. Other well-collected species (e.g., E. candida and E. formosa) that show a peak period of flowering in certain months in nature are strictly annual-flowering in cultiva- tion. POLLINATION BIOLOGY Data on pollination ecology of Amaryllidaceae in general are scant and represent an area sorely in need of investigation. No information on polli- nation of Caliphruria is available. The large, white, heavily and sweetly fragrant flower of E. amazon- ica (subg. Heterocharis) was considered a model moth-pollinated flower by Percival (1965). She not- ed that the nectar level in the tube rises to a maximum height of 2376 tube length, thus effec- tively preventing access to all but long-tongued insects. The large, heavily fragrant flowers of subg. Heterocharis fit the syndrome of sphingid moth pollination (sensu Faegri & van der Pijl, 1979). Other related genera of *'infrafamily" Pancratioi- dinae with similar flower morphology are special- ized for hawkmoth pollination (Hymenocallis: Bauml, 1979; Grant, 1983; Pancratium: Morton, 1965). Floral fragrance is rare in subg. Eucharis, oc- curring in only E. bakeriana, E. castelnaeana, E. formosa, and E. plicata subsp. brevidentata. However, floral fragrance is only weakly developed these species, and in E. formosa the odor is slightly fetid. Vogel (1963) reported euglossine bees visiting Eucharis bakeriana. Visitation by an un- identified euglossine has been reported for other, unidentified species of subg. Eucharis in Peru (J. Schunke, pers. comm.). Unfortunately, neither re- port indicated the sex of the visitor. The phenology of Eucharis (rarely more than one or two flowers open per inflorescence at any one time over à period of two or three weeks, and the often suc- cessive appearance of inflorescences from a clonal clump of bulbs) and the dispersed distribution of plants in the wild suggests pollination by a trap- lining organism (see Janzen, 1971) DISPERSAL The leathery, bright orange fruit of Fucharis subg. Eucharis is a major apomorphy that defines the subgenus. At dehiscence, the contrast between the capsule and the lustrous black or blue seeds creates a striking visual display in the forest under- story, but there are no recorded observations of visitation to the ripe capsules. BREEDING SYSTEM On the basis of greenhouse pollination attempts, virtually all species of Eucharis and Caliphruria demonstrate some degree of self-incompatibility. This observation suggests that most species are predominantly outcrossing. Capsules have been set readily with sibling pollen on all species in culti- vation with the exception of E. amazonica and functionally sterile hybrid taxa (E. x grandiflora, x Calicharis butcheri). Further evidence of out- crossing is the marked protandry of most Eucharis species (with the exception of E. castelnaeana, in which stigma receptivity coincides with anthesis) and the presence of putative interspecific hybrids in nature (E. candida x E. formosa (Meerow, 1988), E. plicata subsp. plicata x E. ulei (Mee- row, in prep.)). Of all species in cultivation, only 7. castelnaeana sets capsules with self-pollen. Autogamy in E. castelnaeana is associated with a number of other divergent character states for subg. Eucharis. This species has a mass-flowering phenology; the smallest flowers in the genus; a green, often tardily dehiscent capsule; a less turgid seed with a dull, rugose testa; and telocentric chro- mosomes. Reproductive biology of Eucharis and Cali- phruria is thus still largely conjectural. Annual flowering patterns, short-term pollen viability, and susceptibility to systemic diseases in cultivation impede greenhouse exploration of these questions, and the rarity of the plants is an obstacle to field studies. The disappearance of populations of these genera and their pollinating agents, concurrent with ain forest destruction, may be the final impediment to investigation of this aspect of their biology. ~ PHYLOGENETIC RELATIONSHIPS Eucharis and Caliphruria have been variously treated as separate genera (Baker, 1888; Bentham & Hooker, 1883; Pax, 1888; Hutchinson, 1959), a single genus (Traub, 1963), and as subgenera of Urceolina (Traub, 1971). As a group, Eucharis, Caliphruria, and Urceolina appear to represent a distinct tribal assemblage within “‘infrafamily” Pancratioidinae Traub (1957, 1963), a group de- limited by various patterns of staminal connation, somatic chromosome number frequently of 2n — 46, and an Andean center of diversity (Meerow, 1985, 1986, 1987a, c). PHYLOGENETIC ANALYSIS Despite a lack of consensus on generic and spe- cific limits in Amaryllidaceae, cladistic analysis has only twice before been applied to such problems 158 Annals of the Missouri Botanical Garden FIGURE 63. — ta states of Urceolina.

The generic limits of Eucharis and Caliphruria in relation to Urceolina, as well as interspecific relationships in the former genera, seemed two areas that would two closely benefit from the application of cladistic analysis. Before assessing these relationships cladistically, a brief review of character states in Urceolina is necessary. Urceolina (ca. 6-8 species; Fig. 63) is so far known only from central and southern Peru on the eastern Andean slopes (Fig. 64) at elevations of 700-2,000 m. The relationships of Urceolina have long been misunderstood, most workers (Baker, 1888; Pax, 1888; Hutchinson, 1959) placing Ur- ceolina near Stenomesson Herbert. Traub (1957) was the first to recognize its affinities with Eucharis. The problem no doubt stemmed from the inclusion of a species of Stenomesson (S. miniatum (Her- bert) Ravenna) in Urceolina as U. miniata (Her- bert) Benth. & Hook. Despite the ventricose aspect of the corolla morphology of 5. miniatum, which is similar to that of Urceolina, the species clearly belongs to Stenomesson as evidenced by its narrow, subpetiolate leaves, the morphology of its staminal cup, and its numerous flat, black seeds (Ravenna, Urceolina is easily distinguished by its brightly colored, urceolate corolla formed by the coherence of the tepals throughout most of their length (Fig. 63A). Vargas (1960) described the genus Pseu- dourceolina to accommodate a species of Urceo- lina in which the tepals are supposedly more laxly coherent. The morphology of the flower in Urceo- lina strongly suggests ornithophily (sensu Faegri & van der Pijl, 1979), i.e., vivid, "parrot" colors, ventricose corolla, pendulous habit, and absence of odor. As in Caliphruria, the staminal cup of Urceolina is reduced to a minute, membranous, basal connation of the filaments, which are oth- erwise linear throughout their length. The leaves of Urceolina, in thickness and lack of both surface plication and marginal undulation, resemble Cali- phruria more closely than Eucharis. At least one species is hysteranthous (U. microcrater Kranzlin), but all species enter a leafless dormant period in the wild. In size the pollen grains of Urceolina (Fig. 63E) are similar to those of Caliphruria. The coarseness of the reticulum is intermediate between that of Eucharis and Caliphruria. In all species of Urceolina the small stigma is capitate and entire (Fig. 63G) versus the trilobed stigma found in Eu- charis and Caliphruria. Urceolina species have 10-20 ovules. The ripe fruit of Urceolina is a thin- walled, yellow-green, turbinate capsule. The seeds of U. microcrater (Fig. 63H) are narrowly oblong, ca. 8 mm long, and 2.5 mm wide, and curved. The seeds have a unique anatomical feature: at the chalazal end, a dam of poorly differentiated tissue separates a "cap" composed of many small cells from the endosperm (Fig. 63J, L). The cells of the “cap” do not have pitted walls with plas- modesmata as is characteristic of the endosperm cells. There is no obvious surface feature on the seed corresponding to the area of this "cap," and its function is unknown. Outgroup selection. Preliminary cladistic analyses of the pancratioid Amaryllidaceae (Mee- row, 1985) indicate that within the Pancratioidi- nae, a large, white, fragrant, crateriform flower with a conspicuous staminal cup (““paneratioid,” cf. Pancratium L.), involved with sphingid moth pollination (Bauml, 1979; Grant, 1983; Morton, 1965), may be symplesiomorphous. In other words, while the pancratioid flower was a major apomor- phy defining the Pancratioidinae as a distinct group within the Amaryllidaceae, it is the ancestral floral morphology from which all other pancratioid taxa have diverged. I have used the term “the pancra- tioid base" tioidinae with this type of flower morphology (Mee- 5). These five genera are Eucharis, Hymenocallis, Pancratium, Pamianthe Stapf, and Paramongaia Velarde. All but Pancratium are entirely neotropical in distribution. The pancratioid to define the five genera of Pancra- row, flower correlates repeatedly with the largest pollen grain size within the Pancratioidinae (Meerow, 1985; Meerow € Dehgan, 1985). Putatively basal complexes within each pancratioid lineage also have numerous ovules per locule (ca. 20 or more), a character state considered primitive in the Ama- ryllidaceae (Traub, 1963). Pollen morphology provides the best evidence for the monophyly of the Pancratioidinae. The large pollen grains of most species of the pancra- tioid base are uniformly coarsely reticulate, with some in each genus exhibiting a striking exine E.

None- theless, separate origins of the pancratioid flower in the Neo- and Paleotropics cannot be ruled out. That the neotropical tribes of the Pancratioidi- nae represent a monophyletic group is a much more robust hypothesis. All neotropical pancratioid gen- era have 2n = 46 as the most common somatic chromosome number (Di Fulvio, 1973; Flory, 1977; Meerow, 1985, 1987a, c; Williams, 1981).

All paleotropical pancratioid genera have 22 or 20 chromosomes (Ponnamma, 1978; Zaman & Chakraborty, 1974). Pancratium (ca. 17 species) and two species of Hymenocallis (H. quitoensis Herbert and H. he- liantha Ravenna) were used as the primary out- groups in the analyses presented. Character state data on these taxa were accumulated from study of living material, herbarium specimens and liter- ature (Björnstad, 1973; Meerow & Dehgan, 1985; Morton, 1965; Ponnamma, 1978; Ravenna, 1980; Traub, 1962; Werker & Fahn, 1975). Pancra- tium is putatively the least derived genus of the pancratioid base (Meerow, 1985). It is the only paleotropical genus of the group, and the o member with 2n = 22 (Ponnamma, 1978), con- sidered by most workers as the ancestral somatic chromosome number in the family (Flory, 1977; Goldblatt, 1976; Meerow, 1984). The two species of Hymenocallis are undoubt- edly a monophyletic group. They are the only two mation series for cladistic analysis of Eucharis and Cal- iphruria. * = unordered multistate character.

All evidence suggests that possession of phy- tomelan is the ancestral condition in the Amaryl- lidaceae, and despite several independent losses, no reversal to the ancestral state has been proposed (Dahlgren & Clifford, 1982; Dahlgren & Ras- mussen, 1983; Dahlgren et al, 1985; Huber, 1969). Hymenocallis quitoensis was segregate into a separate genus, Lepidochiton Sealy (1937) on the basis of phytomelanous seed. Both H. qui- toensis and H. heliantha are ephemeral compo- nents of the xeric flora of southwestern Ecuador and northwestern Peru, and differ only in flower color. Traub (1962) considered H. quitoensis a relict and the most primitive species of Hymeno- callis on the basis of ovule number (ca. 20 per locule; 2-10 occurs in all other species) and chro- mosome number (2n — 24, based on Snoad, 1952); however, collections from Peru and Ecuador that have examined have 2n — 34. These are the lowest reported chromosome numbers in the genus (Flory, 1976). These species will be called Lepi- dochiton in the following discussion. Additional analyses were run using other members of the pancratioid base as outgroups (Hymenocallis subg. Hymenocallis, H. subg. Ismene (Salisb.) Baker ex Traub, Pamianthe, and Paramongaia). The re- sulting cladograms were either equal in length or slightly less parsimonious than those presented here; they did not show changes in the resolution of terminal taxa from the cladograms presented. Ordered characters. Ten of the 18 multistate characters (Table 2) used in these analyses (8, 9, 0, 13, 24, 25, 27, 28, 30, and 35) were ordered into linear transformation series. Study of char- acter state correlations among all genera of the pancratioid Amaryllidaceae (Meerow, 1985, 1987a, c) strongly suggests that flower size reduction (8), loss of floral fragrance (9), flower number (10), pedicel length (13), staminal tooth length (25), style length (30), and reduction in ovule number (35 have evolved in this stepwise manner with no evi- dence of reversal. Numerous ovules per locule (20 or more) characterizes all basal genera of the pan- cratioid Amaryllidaceae and is generally considered the ancestral condition for the family (Traub, 1962, 1963; Traub & Moldenke, 1949).

Complete loss of stam- inal dentation often accompanies overall phenetic divergence among the pancratioid genera (Meerow, 1985, 1987c; see E. astrophiala in this paper). Polymorphism for the character is not uncommon, however, and is conceived in the transformation series as the intermediate between the two fixed states of toothed or edentate stamens. Ordering of pollen size (27) and exine morphology (28) is based on data presented in Meerow (1985, 1987c) and Meerow & Dehgan (1985), as well as unpublished palynological data accumulated for many genera in the family. A single character, chromosome number (41), was coded in additive binary on the basis of much literature on amaryllid cytology (Flo- ry, 1976, 19777; Goldblatt, 1976; Lakshmi, 1978; Meerow, 1984, 1987b; Ponnamma, 1978; Sato, 1938; Snoad, 1952), which strongly supports this concept of chromosome number evolution. Results and discussion. monious trees without any differences in topology resulted when either Pancratium or Lepidochiton was used as the outgroup. The twelve trees differed only in the branch lengths of a few internal nodes, and resolution of terminal taxa did not change among them. One of the twelve with Pancratium used as outgroup is illustrated and discussed in detail (Fig. 65). The cladogram has a length of 2.4 steps (fractional lengths are a result of weight scaling), and a consistency index (Cl; Kluge & Farris, 1969) of 0.487. Lepidochiton is the first terminal EU to resolve in the cladogram after the outgroup, Pancratium. Character state changes from the outgroup to the ancestral node of Lepi- dochiton (flower number reduction, globose seeds) could not be polarized. Uniflory, perianth color polymorphism, brown seed testa, and 2n = 34 are the four apomorphies of Lepidochiton.

The larger monophyletic group represents E. sanderi, Eucharis subg. Eucharis, Caliphru- ria, and Urceolina. Five apomorphies define the ancestral node: densely striate abaxial cuticle, un- dulate anticlinal walls (homoplasious with E. ama- zonica), deeply cleft staminal cup, polymorphism in staminal dentation, and lustrous testa. It is thus obvious that subg. Heterocharis is paraphyletic according to this cladogram.

The next monophyletic group is supported by eight apomorphies and comprises Eucharis subg. Eucharis, Caliphruria, and Urceolina.

Eucharis clade are subulate free filaments (homoplasious with E. amazonica), loss of exine dimorphism (homoplasious with the ancestor of E. amazonica and E. moorei), and an orange capsule. Within this clade, two monophy- letic groups are evident. The larger of the two is efined by a single apomorphy, plicate leaves. Eu- charis formosa is the first terminal EU to resolve but terminates a zero-length branch. Eucharis can- dida also terminates a zero-length branch, the an- cestral node of which is defined by two apomor- phies: loss of floral fragrance and reduction in ovule number. The next monophyletic group encom- passes all species of subg. Eucharis with about five flowers and about two ovules per locule. The hy- pothetical ancestor of Eucharis astrophiala and E. caucana forms an unresolved polytomy at the ancestral node with E. cyaneosperma, E. ulei, and the hypothetical ancestor of tetraploid species £. bonplandii and E. bouchei. Three apomorphies define the ancestral node of the second clade within subg. Eucharis: a plicate staminal cup, a reversal to shallowly cleft staminal cups, and a reversal from polymorphism in staminal dentation to fixed dentation. Eucharis bakeriana is the first terminal EU to resolve, on the basis of two apomorphies: loss of leaf margin undulation and increase in pollen size. The remaining species are the smallest-flowered species in the subgenus. The remaining apomorphies at the ancestral node are a decrease in pollen size and ovule number. The first terminal EU to resolve is E. corynandra, from a zero-length branch. It should be noted, however, that two autapomorphies of this species, a short staminal cup and club-shaped free fila- ments, were not included in the data matrix. The ancestor of the two subspecies of E. plicata form a monophyletic group with E. castelnaeana on the basis of style length. Subspecies brevidentata ter- minates a zero-length branch. Kucharis castel- naeana has the greatest patristic distance of the three EUs (seven apomorphies) The final large clade constitutes Caliphruria, Urceolina, and the cladistically basal E. oxyandra. Apomorphies are nonundulate leaf margins, small flowers, loss of floral fragrance, urceolate corolla (which does not apply to E. oxyandra, the corolla shape of which is either crateriform or campanulate but could not be coded as one or the other with certainty), reduction of the staminal cup, loss of androecial pigmentation, and moderately coarse exine. The character state of E. oxyandra is un- known for four of these seven. Within this mono- phyletic group, Urceolina and the hypothetical ancestor of Caliphruria resolve as sister groups on the basis of three apomorphies: declinate or pendent flowers via pedicel habit, straight tubes, and small pollen grains. Nine and eight apomor- phies define Urceolina and the hypothetical ances- tor of Caliphruria, respectively. Within Cali- phruria, the sole representative of the genus outside Colombia, C. korsakoffii is the first terminal EU to resolve, on the basis of three apomorphies: straight anticlinal epidermal walls, short tubes (homoplasious with C. tenera), and brown testa. Caliphruria subedentata terminates a zero-length branch from the hypothetical ancestor of the Co- lombian species of the genus. Apomorphies at the ancestral node are finely reticulate exines, loss of exine dimorphism, compressed seeds, and rugose testa (the states for the last two characters are known only for C. subedentata). Caliphruria hart- wegiana and C. tenera form a monophyletic group on the basis of toothed stamens and reduced ovule number, but C. hartwegiana terminates a zero- length branch. The clado 70 parallel origins of character states and 29 re- versals (unordered characters not included). This may raise questions concerning the homology of characters that manifest low consistency. If the data matrix is analyzed with all characters removed that exhibit three or more independent origins for the same state (characters 3, 4, 8, 9, 10, 18, 19, 24, 25, 27, 29, 35, 37, 38, 40), the three trees that result have a fourfold increase in zero-length gram presented in Figure 65 contains 166 Annals of the Missouri Botanical Garden branches and unresolved polytomies. Invariably, it is androecial characters (including pollen size) in which a great deal of homoplasy has occurred. Three of all the androecial characters, 24 (staminal dentation), 25 (length of teeth), and 27 (pollen size), are particularly homoplasious. When the data matrix was run with only these characters deleted, no change occurred in the resolution of terminal taxa from the cladogram in Figure 65. Finally, the data matrix was analyzed with all staminal cup characters (19, 20, 21, 22, 23, 24, 25), and pollen size (27) deleted. The resulting three cladograms (differing only by one internal branch length) placed Caliphruria and Urceolina within a monophyletic group including E. bakeriana, E. bonplandii, and . bouchei, on the basis of a single apomorphy, nonundulate leaf margins. Regardless of how the character-state data are manipulated, a number of monophyletic groups appear particularly robust. That Kucharis, Cali- phruria, and Urceolina represent a monophyletic group is uncontested. The monophyly of Eucharis moorei and E. amazonica is also strongly sup- ported, and these two species are the most cla- distically basal of the eucharoid lineage. These species have the greatest number of putatively primitive characters and seem to represent the more ancestral species in the genus. Nonetheless, according to the cladogram in Figure 65, retaining subg. Heterocharis in Eucharis renders the genus paraphyletic. Subgenus Heterocharis is a fairly heterogeneous group from the perspective of apo- morphic characters alone. Each of the three species may be characterized by autapomorphies, but only plesiomorphies join them. By including subg. Het- erocharis in Eucharis, Eucharis becomes para- phyletic according to this cladogram. However, it should be noted that it is unknown whether sec- ondary petiolar bundles (which require fresh ma- terial to observe), an important apomorphy which links E. amazonica and E. moorei, are present in E. sanderi. In the generalized sense, the distri- bution of subg. Heterocharis is quite broad, from Colombia to Peru (Fig. 64). However, each of the three species of subg. Heterocharis itself are only narrowly distributed. Fucharis sanderi is known only from the Chocó region of Colombia. Eucharis amazonica is found natively only in the middle Rio Huallaga valley of Peru. Eucharis moorei has been collected outside of Ecuador only once. More significantly, E. moorei is the only species of Eu- charis found on both sides of the Andes. I believe that all three species of subg. Heterocharis rep- resent the relictual remnants of the ancestral eu- charoid complex, each of which has remained iso- lated long enough to evolve its respective cohort of autapomorphies. The sister group relationship between Urceolina and Caliphruria also seems to be a robust cladistic Pee with E. oxyandra potentially ancestral ot S 3^ Ie] > E m. an s À b: g 3 a i. | & a e - e z O 5 o E S | <= logical intermediacy (androecium and pollen mor- phology) between Eucharis and Urceolina. it is known only from bulbs found in local, transient cultivation in Peru, near the single recorded point of geographic sympatry between Eucharis (E. amazonica) and Urceolina (U. microcrater). The absence of much character state data, but partic- ularly those on fruit and seed morphology, further occludes resolution of its phylogeny, and any of several hypotheses concerning its origins are pos- sible (see Taxonomic Treatment). Kucharis leh- mannii, which usually resolves within a cladistic “no man’s land" between paraphyletic subg. Het- erocharis and all other clades, presents a similar problem, though Regel’s (1889) figure strongly suggests affinity to subg. Eucharis. In the initial analyses, in which all multistate characters were treated as unordered, this poorly known species resolved as sister group to E. bouchei. 1 believe that E. lehmannii is a sister species to E. caucana, to which it bears much phenetic resemblance, and that its unusual resolution in the cladogram is a result of the great deal of missing character state data. Fruit and seed morphology clearly place £. caucana in subg. Eucharis, even though it shows as much novelty as E. oxyandra or E. lehmannii in other characters. Excluding E. lehmannii and E. oxyandra, Eu- charis subg. Eucharis forms phyletic group. Species with five flowers and two ovules per locule (E. astrophiala, E. cyaneosper- ma, E. ulei, along with the tetraploids, E. bon- plandii and E. bouchei) form a very natural group with karyotypic similarity as well (Meerow, 1987b). The sister species relationship of Eucharis cau- cana to E. astrophiala within this group may be as equivocal as the basal resolution of E. lehman- 1 1 Cical 1) mono- nii, since it is based on two apomorphies (pollen size and lack of staminal dentation), the latter of which is highly homoplasious. I believe the reversal in ovule number necessary for E. caucana to share common ancestry with E. astrophiala is very un- likely. Eucharis candida and E. formosa, two often sympatric (and possibly sibling) species, are cla- distically close and basal to the five-flowered clade. The small-flowered species (E. castelnaeana, E. corynandra, and E. plicata) form another very Volume 76, Number 1 1989 Meerow 167 Eucharis and Caliphruria r AMA 18 23* 27+< 5 6*< 29* 40* Euc hats subg.

Refer to Table 1 for EU designations. natural group. The position of E. bakeriana as basal to this clade, largely on the basis of a plicate staminal cup, may be equivocal. Karyotype anal- ysis (Meerow, 1987b) suggests putative relation- ship of E. bakeriana to E. formosa. An alternative hypothesis of phylogenetic rela- tionship is presented in Figure 66. The cladogram is a user-generated tree in which Caliphruria and Urceolina are placed as sister groups to a mono- phyletic Eucharis. The topology of subg. Eucharis in this cladogram represents my concepts of their evolutionary relationships based on phenetic re- semblance, phytogeography, and chromosome data. The major differences from the cladogram in Figure 65 are the sister species relationship of E. caucana and E. lehmannii, the ancestral node of which forms a monophyletic group with the five-flowered, two-ovuled species complex; and the positioning of E. oxyandra as part of the small-flowered species group of subg. Eucharis. This user-generated cladogram had a length of 100.6 steps, with a CI of 0.443. There are 82 parallelisms represented among the character state changes, and re- versals. The user-generated tree (Fig. 66) is thus somewhat less parsimonious than the cladogram in Figure 65. Of particular interest in the user-gen- 168 Annals of the Missouri Botanical Garden erated cladogram is the resolution of the larger monophyletic groups constituting genera or sub- genera, and the accompanying character state changes within these clades. In Figure 66, a monophyletic subg. Hetero- charis is supported by seven apomorphies, four of which are reversals (unordered characters not counted). Some of these reversals are very unlikely (e.g., reversal to larger, heavily fragrant flowers; see previous discussion of ordered characters) and would thus represent retention of ancestral states. In the user-generated tree, a monophyletic subg. Eucharis is supported by a greater number o apomorphies (eight in Fig. 66) than in the parsi- mony cladogram (three). Caliphruria as a mono- phyletic group is best supported by Figure 66 (ten apomorphies) versus eight in Figure The results of these various cladistic treatments illuminate the problems inherent in phylogenetic reconstruction of large, character state data sets, and particularly with taxa whose evo- lution has involved large-scale homoplasy. The user- generated cladogram in Figure 66 represents my preferred hypothesis of phylogeny within the Eu- charideae; nonetheless I cannot deny the com- pelling evidence that Eucharis, by the inclusion of subg. Heterocharis, may be paraphyletic. From an orthodox cladistic perspective (Wiley, 1981), Traub's (1971) concept of a single poly- morphic genus, Urceolina, is supported by the criterion of parsimony. From a phenetic (and prag- matic) standpoint, I find this unsatisfactory due to the close phenetic relationship between subg. Het- ris. This relationship is most conspicuous if one compares Eucharis bakeriana and E. formosa (the most basal species of subg. Eucharis) with E. amazonica and E. moorei (subg. Heterocharis). | prefer to recognize Urceolina and Caliphruria as distinct genera, despite the atten- dant risk of a paraphyletic Éucharis. I do not believe that Urceolina and Caliphruria necessarily erocharis and Eucha share an immediate common ancestor—the three apomorphies that define their sister group rela- tionship in Figure 65 (reversal to straight tubes, flower habit, and smaller pollen grains) are homo- plasious within the Eucharideae as well as in other tribes of the Pancratioidinae (Meerow, 1987c; Meerow & Dehgan, 1985). Until further data allow a more accurate understanding of their relation- ships, I also prefer to maintain E. lehmannii and E. oxyandra as species of Eucharis subg. Eucha- ris, allied with the small-flowered species with nu- merous ovules per locule. Without study of living material, and particularly knowledge of fruit char- acters, I am unwilling to declare E. oxyandra a sister taxon to Urceolina and Caliphruria. Ashlock (1971, 1972, 1979, 1984) has re- peatedly argued for the acceptance of paraphyletic groups in evolutionary systematic classifications. He defined two subclasses of monophyletic groups: holophyletic, which contain all descendents of the stem ancestor, and paraphyletic, those which do not. Ashlock (1979: 449) rejected ““the automatic conversion of the cladogram into a classification.” Meacham & Duncan (1987) have elaborated on the term *'convexity," first proposed by Estabrook (1978), which attempts to resolve the concepts of monophyly, holophyly, and paraphyly. Meacham & Duncan concluded that Ashlock's (1979) ad- vocation of overa luti y similarity as a com- ponent of classification schemes, rather than strict cladistic topology alone, is sound, and they dis- cussed the mitigating factors surrounding cladistic methodology (e.g., uncertainty of character state polarities, the speculative nature of phylogenetic reconstructions, among others) which compromise a direct translation of cladogram into classification. and Humphries & Chappill (1988) have responded vociferously to Cronquist's (1987) critique. Don- oghue & Cantino (1988: 108) assail paraphyletic higher taxa as “artificial classes created by tax- onomists who wish to emphasize phenetic 'gaps', and that formal recognition of such taxa conveys a misleading picture of common ancestry and char- acter evolution." The enormous amount of homoplasy evident within the highly canalized Amaryllidaceae creates great difficulty in phylogenetic reconstruction (Meerow, 1985, 1987c). In the analyses of Eu- charis and related genera, missing character state data further weaken the argument for adopting ad hoc the most parsimonious phylogeny as the basis for classification. At present, I prefer to accept a less parsimonious phylogeny as represented by the user-generated topology in Figure 66 until such time as cladograms can be generated with consis- tency indices greater than 0.5. Towards this end, work is continuing with careful application of se- lected character weighting (Neff, 1986; Wheeler, 1986). In three neotropical lineages of the Pancratioi- dinae, parallel trends in the evolution of floral mor- phology have occurred (Meerow, 1985, 1987c). In each case, taxa with smaller, tubular or ven- tricose, brightly colored flowers with reduced stam- inal connation, and without noticeable fragrance Volume 76, Number 1 1989 Meerow 169 Eucharis and Caliphruria have apparently diverged from taxa possessing a large, white, fragrant, crateriform flower with a staminal cup (Meerow, 1985, 1987c). Each lin- eage appears to be a monophyletic group on the basis of vegetative and ovarian morphology, as well as chromosome number (Meerow, 1985, 1987c; Traub, 1963). A similar pattern occurs in all three lineages: 1) floral morphology of “derived” taxa 3 gap an Lo TR pollination syndrome, and 2) "derived" taxa are found, entirely or in part, at iid elevations than apparent ancestral taxa. Eucharis and Urceolina, as documented in this paper, present one such case. Pseudosteno- messon Velarde, submerged by Traub (1980) into Hymenocallis as section Artema, presents a par- allel situation within the Hymenocallis lineage (Meerow, 1985; Meerow & Dehgan, 1985). Tribe Stenomesseae contains two small genera, Pa- mianthe and Paramongaia, with ancestral floral morphology and contains a large genus, Steno- messon, with derived morphology (Meerow, 1987c). In the Hymenocallis and Eucharis lineages, the pancratioid floral morphology has radiated to a far greater extent than the putatively ornithophilous divergence (Pseudostenomesson an rceolina, respectively). In the Pamianthe- Paramongaia/ Stenomesson lineage, the derived genus, Steno- messon (35-40 species), has speciated to a great- er degree than taxa with the ancestral pancratioid flower (Pamianthe: 2 species, Paramongaia: monotypic). he high level of divergence in neotropical pan- cratioid tribes may be primarily a factor of two causes, 1) the uplift of the Andes in the Pliocene (van der Hammen, 1974, 1979), creating much opportunity for geographic isolation, and 2) greater genetic adaptability via tetraploidy to new ecolog- ical zones. The occurrence of rare hybridization in nature between the relict complex represented by Eucharis subg. Heterocharis and both Caliphru- ria (X Calicharis butcheri) and Urceolina (x Ur- ceocharis edentata) may be further indication that the evolution of these genera was geologically re- cent. TAXONOMIC TREATMENT SUBSPECIFIC TAXA The rank of subspecies is used once in this treatment (E. plicata) to designate strong mor- phological divergence coupled with geographical isolation that I accept within specific limits. The rank of variety is used in a case (E. bouchei) where both the morphological and geographic components of divergence are weaker but appear to represent the first stages of speciation within a tetraploid semispecies complex (Meerow, 19874). CRITICAL MEASUREMENTS Measurements of vegetative and floral parts in the following species descriptions are derived from examination of dried material (floral parts after rehydration in 3% solution of Aerosol OT brought to boil) supplemented with examination of fresh or FAA-preserved material when available. 1 found less than 5% difference between measurements of dried and fresh or spirit-preserved material of the same collection when available. A NOTE ON THE KEYS Species of Caliphruria and penas subg. Het- erocharis are separable by di ters very amenable to key construction. dia the keys to these two groups, any worker should be able to identify material referable to described taxa wheth- er in the field or the herbarium. The enormous degree of variation exhibited by species of subg. Eucharis, however, made key construction difh- cult. A number of the species overlap to at least some degree with one or more other species in virtually all quantitative morphological characters. As a consequence, sometimes I have had to rely on characters observable only with living material. With perseverance, it should be possible to key out all but the most depauperate herbarium specimens of subg. Eucharis. Collectors should note such characters as leaf plication and undulation, floral fragrance, tepal habit, and pigmentation and pli- cation of the staminal cup in their notes when preparing specimens of Eucharis.

The species previously has been de- limited by the absence of staminal dentation; how- related species E. formosa and E. ulei. Peruvian populations of E. candida are variable in the shape of the staminal cup (Figs. 68, 69), even among flowers of the same inflorescence. Eucharis candida is most common throughout the upper Napo Valley in eastern Ecuador and is very often sympatric with the larger-flowered and Variation in a single Peruvian population of Eucharis candida pu 14155-B, FLAS).— 69. Flower with cylindrical staminal c more widely distributed E. formosa (Figs. 71, 72). In one instance, two specimens (Harling & An- dersson 11719), one each of the two species, were collected under the same number. To date, no species of Eucharis other than these two have been collected north of the Pastaza valley in eastern Ecuador. On the basis of herbarium study alone, Ecuadorean populations of these two taxa form a mosaic that seemed taxonomically insoluble until living material of both species from several pop- ulations was collected and flowered. Phenetic and karyotype analyses (Meerow, in press) support their recognition as distinct species and suggest that E. E. formosa have hybridized in at least one area of sympatry. Eucharis candida may be separated from E. formosa by its smaller leaves and flowers, complete candida an absence of fragrance (E. formosa produces a mild, "sour" odor), and generally fewer ovules per locule (though both species are variable in ovule number). On the basis of known collections, Eucharis for- mosa is slightly better represented in the Pastaza valley than E. candida. 2. Eucharis formosa Meerow, Sida 21: 29- 49. 1987. TYPE: Ecuador.

Like the closely re- lated E. candida, E. formosa has a wide elevati range, possibly in part from cultivation oe 1987e). The flowers emit a mild and unpleasant “sour” odor. Eucharis formosa is larger in all parts than E. candida and generally has more ovules per locule. The conspicuous horn on the apiculum of the outer tepal is characteristic of Ecuadorean populations of E. formosa (Fig. 67Ai); this char- acter is not obvious in Peruvian collections. Forms with toothed or edentate staminal cups occur throughout the range of this species without any observable geographic pattern (Fig. 70B).

A second collection (Schunke 1417 1), from the same general vicinity of Peru as Schunke 14174, has only shallowly plicate leaves and reduced pigmen- tation of the staminal cup (Figs. 76, 77). At pres- ent, too little is known about E. formosa in Peru to justify recognition of subspecific taxa. 3. Eucharis bakeriana N. E. own, Gard. Chro 1890, s.n., in part (holotype, K).

SAN MARTÍN: 17 km NE of Tarapoto on road to Yurimaguas, trail along stream to waterfall, wet premontane forest on rocky hills, 6°30'S, 76°20’W, 800 m, 21 July 1982 (fr), Gentry et al. 37852 (MO); vicinity of Tarapoto, no other data, flowered in cultivation from material collected by L. Besse, Meerow 1108 (FLAS). The type of E. bakeriana was prepared from living material supposedly collected in Colombia. When I examined the type specimen, only the several large flowers present in the fragment packet resembled the figure that accompanied Brown's (1890) description of E. bakeriana. The mounted material was referable to the smaller-flowered F. candida. At the time, I thought that E. bakeriana might represent an aberrant form of E. candida. Several years later I received a bulb of a Eucharis collected near Tarapoto, Peru, by Libby Besse of SEL. The flowers that grew from the bulb bore an exact resemblance in habit and staminal cup morphology to E. bakeriana, though with consid- erably more ovules per locule. At present, E. baker- iana is known only from the type, the Besse ma- terial, and a fruiting specimen referred to this species on the basis of leaf size Eucharis bakeriana is distinct from E. formosa, its closest phenetic relative, by its nonpendent flow- ers that are perpendicular to the vertical axis of the scape, very shallowly cleft staminal cup (« 1 mm, vs. 2 mm in E. formosa), short subulate portion of the stamen, and sweet floral fragrance (slightly fetid in E. formosa). In leaf size and karyo- type, E. bakeriana is very similar to Peruvian material of E. formosa (Schunke 14174) but dif- fers by its greater number of subtelocentric chro- mosomes and the submetacentric morphology of the second-largest pair (Meerow, 1987b). The leaves are only shallowly, if at all, plicate and are thicker. 4. Eucharis ARM (Kunth) Traub, Pl. Life 7: 40. 1951. Hymenocallis bonplandii Kunth, B Pl. 5: 666. 1850. TYPE: Co- lombia.

The species is known only from Colombia, and has been rarely collected. Among Amazonian species, E. bonplandii has the greatest phenetic relation- ship to E. ulei, with five similarly sized flowers and two ovules per locule in common. It may be sep- arated from £. ulei by having succulent, glaucous leaves and short petioles. The staminal cup of F. bonplandii is pigmented pale yellow at its base; that of E. ulei is marked green. Eucharis bon- plandii and E. bouchei are the northernmost species of subg. Fucharis, and thus may form a mono- phyletic, tetraploid group (Meerow, 1987d). Both species have relatively short petioles.

It is also the most variable species in the genus, in characteristics that elsewhere jus- tify specific delimitation. Patterns of variation in floral size and tube and limb habit form a complete mosaic throughout the range of E. bouchei that shows little or no geographic consistency (Meerow, 19874). Staminal cup morphology (Fig. 70C) does, however, demonstrate a fair degree of geographical consistency, and it is chiefly on this basis that I have recognized var. bouchei and var. darienensis. Variety dressleri, rarely enountered mixed with var bouchei, presents a special case, discussed below. Variety bouchei, most common around El Valle de Antón in Coclé Province, is recognized by its largely edentate staminal cup in which the trape- zoidal free filament is not markedly constricted distally into a narrow subulate portion (Figs. 70Ci, ii, 82C). The staminal cup of "a darienenis, found both in Panamá and Darién provinces, is obtusely bidentate or lobed (Fig. 70Civ) The free filament constricts distally into a narrow (< 2 mm) subulate portion. These two varieties occur in close proximity in one location, near Cerro Campana in Panamá Province (Fig. 83). The rare var. dressleri (Fig. 82Ai), with its acutely toothed staminal cup (Fig. 70Ciii) and shal- lowly trigonous ovary, occurs close to populations of var. bouchei, which is an unstable tetraploid, producing at least some cells with diploid (2n — 46) chromosome number (Meerow, 1987d). This variety also does not express either heterozygous or additive banding phenotypes for isozymes o aspartate amino transferase, which otherwise char- acterizes electrophoretic phenotypes of E. bouchei (Meerow, 19874). The unprecedented degree of variation in £. bouchei is likely the result of two main factors: (1) the species is tetraploid, and (2) it probably rep- resents a geologically recent colonization of Central America by this primarily northern Andean and Amazonian genus (Meerow, 19874). Northwesternmost populations representing var. bouchei have the most derived androecial mor- phology (Fig. 70Ci, ii) relative to southeasterly populations (var. darienensis, Fig. 70Civ). The latter have staminal cups similar to the generalized morphology characteristic of Andean and Ama- zonian species of subg. Eucharis. This suggests that general movement of E. bouchei in Central America has been away from the Colombian bor- der. The occasional presence of E. bouchei in Costa Rica is not surprising, but the two reported collec- tions from Guatemala (Wendland 207 and Skutch 1585) represent a substantial disjunction, or two disjunctions, since the two collections represent different varieties. Given the history of cultivation of Amazonian Eucharis by Indian people for me- dicinal, ceremonial, and possibly ornamental use, the same may have held true in Central America. 6.

Thirteen chromosomes are out of the figure frame chromosome pair of E. astrophiala is submeta- centric, unlike the metacentric pair of all other species of the genus I have examined (Meerow, 1987b). It is the only species of the subgenus found exclusively on the western slopes of the Andes south of Colombia. It occurs sympatrically in some lo- calities (fide Dodson & Gentry 12815 and Meerow & Meerow 1140) with E. moorei, though the latter grows at slightly higher elevation in these areas. Eucharis astrophiala is the only species of subg. Eucharis that enters a definite rest period during the short dry season of the northwestern and cen- tral western Ecuadorean Andes. New growth com- pletely ceases, though one or two leaves may persist for the duration. 7. Eucharis caucana Meerow, sp. nov. TYPE: Colombia.

The recent receipt of material collected by Phil Silverstone-Sopkin and coworkers is the first col- lection of the subgenus in the largely deforested Cauca valley since 1922. Eucharis caucana has the largest pollen grains in the genus and is the only known hexaploid species of Eucharis, with a somatic chromosome number of 2n — 138 (Fig. 88). As with most other South American peripheral isolates from the Amazonian center of distribution for subg. Eucharis (E. asto- phiala, E. corynandra, E. lehmannii, and E. ox- yandra), E. caucana exhibits some degree of mor- phological novelty; in this case, reduction of staminal connation, funnelform-campanulate perianth, and very large pollen grains. Nonetheless, E. caucana has fruit and seed morphology typical of subgenus Eucharis. By its reduced staminal cup E. caucana shows affinity with E. lehmannii from which it differs by having larger flowers, shorter pedicels, straighter tubes, edentate androecia, and fewer ovules per locule. By its high polyploid chromosome number, short pedicels, and flower size, E. caucana shows similarity to certain populations of E. bouch- ei var. bouchei. Some collections of the latter from Colón Province exhibit funnelform-campanulate perianth morphology and floral tube habit like E. caucana. The discovery of this hexaploid species in Colombia supports the hypothesis that a poly- ploid complex of Eucharis may have existed in Colombia in the recent geologic past (Meerow, 987d). 8.

Eucharis, extending north from its Peruvian center of distribution into Co- lombia and south to Bolivia (Fig. 81). The species is best recognized by its primarily narrow-elliptic leaves, chiefly five-flowered inflorescence, tube length of ca. 3-4 cm, limb spread of 4-5 cm, and reduced ovule number (generally two per locule, Fig. 89C). Both flower and ovule number have become nearly fixed throughout the range of the species. Eucharis castelnaeana is sympatric with E. ulei at times but tends to occur on seasonally inundated soils. Flower size and number, ovule number, and chromosome morphology (Meerow, 1987b) suggest close relationship to E. cyaneo- sperma, which has different tube morphology, a deeply trigonous ovary, and blue-coated seeds. Ravenna (1982: 50) described Urceolina moana, citing the “absence of lobes, or teeth, in the cup." The single, poorly preserved, fragmentary flower of the holotype, however, had stamens at least shortly dentate to quadrate. As in E. candida and E. formosa, androecial toothing in E. ulei has little taxonomic significance. The androecial morphol- ogy of E. moana is well included within the range of variation for this character in £. ulei (Fig. 70D)— several collections of E. ulei have completely eden- tate staminal cups (e.g., Meerow et al. 1024, Plow- man & Kennedy 5811, Prance et al. 13915). Much the same argument applies to the likewise synonymous E. boliviensis (Ravenna, 1988), rep- resented by the only specimen of E. ulei collected in Bolivia. The only other collection assigned by Ravenna (1988) to E. boliviensis (Cardenas 1553) belongs to E. cyareosperma. Eucharis ipariensis, inexplicably described by Ravenna (1982) as allied to E. mastersii (= E. x grandiflora of subg. Het- erocharis), is also indistinguishable from numerous collections of E. ulei. Krànzlin (1913) and Macbride (1936) noted the dissimilarity of the two specimens comprising the holotype of E. ulei (Ule 57376), one in flower, the other in fruit. I have assigned the fruiting specimen (Ule 5737b), with blue seeds, to E. cyaneosperma Meerow. When a putative isotype of Ule 5737 was received from MG, it proved to represent E. castelnaeana. Ule thus collected three species un- der a single number, an unsurprising occurrence in areas where several Eucharis species are sym- patric. 9. Eucharis cyaneosperma Meerow, Sida 12: 29-49. 1987.

The species ap- pears very similar to E. ulei but differs by having usually shorter leaves, different tube morphology (abruptly curved at the base in E. cyaneosperma, sinuously curved in F. ulei), irregularly dentate to quadrate staminal cup (Fig. 89A), deeply trigonous ovary, and different seed color. In the southern part of its range, E. cyaneosperma occupies more upland sites than are usually characteristic of F. ulei. 10. d Mer in Regel, Gartenfl. 38: 13-314, 1300, fig. 1. 1888.

The short staminal cup and dis- tinctive club-shaped free filaments (Fig. 90H) are the principal unique characters of this species. I cannot, however, confirm Ravenna's (1978) de- scription of the anthers as densely pubescent. The collection locality suggests that it is an upland isolate from the Amazonian center of the subgenus, the plant having colonized the lower limits of the “ceja de la selva" forest formations in Cajamarca Department of Peru. 12.

The collector's field notes (UC) indicate that three bulbs were found at the type locality (Fig. 91) “exposed on surface of ground with evidence of past cultivation, in deep shade near abandoned hut above road. The third bulb aue to be Urceolina urceolata (R. & P.) M. L. Gree This unusual species has the smallest staminal cup of any Peruvian species of Eucharis subg. Eucharis (Fig. 90B). The long, almost linear, free filaments are another unusual feature of the an- droecium. The polymorphism of the staminal cup (both edentate and obtusely dentate forms repre- sented in the isotypes, Fig. 90B) is puzzling and adds further credence to my suggestion that this character has been over-weighted as an indicator of species delimitation in the alpha-taxonomic lit- erature relating to the genus. Alternatively, it is possible that the two bulbs found by the collector and representing this species were of two different origins. In publishing Urceolina oxyandra, Ravenna (1983) was apparently unaware of the unusual situation in which the species was found, having examined only a duplicate at USM, which seems to have lacked the detailed field notes of the col- lector. He argued that the unusual morphology of the androecium (reduced staminal cup and long, narrowly subulate filaments), similar to that of Ur- ceolina, supported the inclusion of Eucharis within Urceolina (Traub, 1971), a position he recently reversed (Ravenna, 1985). This type of androecial morphology is characteristic of two putative inter- generic hybrids between Eucharis and Urceolina, X Urceocharis edentata Wright (1910) and x U. clibranii Masters (1892). Given that the plant was discovered as an artifact of cultivation in company with a bulb of Urceolina, and in a geographic area of loose sympatry for the two genera, I thought it possible that E. oxyandra might represent a hybrid between Eucharis and Urceolina. X Urceocharis edentata was suppos- edly collected in the wild in Peru (Wright, 1910). Pollen of E. oxyandra, however, stains 100% with Alexander's (1969) stain. Both x U. edentata and X U. clibranii produced very little pollen (Wright, 1910), an observation confirmed when I examined specimens of both hybrids (ex hort. BM). Pollen grain size of the species is more like that of Eu- Volume 76, Number 1 1989 Meerow 199 Eucharis and Caliphruria charis subg. Eucharis, but exine sculpturing re- sembles that of Urceolina (Meerow & Dehgan, 1988). Fertile hybrids between closely related gen- era are not unknown in Amaryllidaceae (Traub, 1963). Alternatively, Eucharis oxyandra might be a relict taxon close to the ancestor of Urceolina, a genus whose divergence from Eucharis may have been relatively recent (see previous section). Phy- logenetic analysis supports this latter hypothesis. At present, it seems best to treat E. oxyandra as a species of Eucharis, even though its known shared characteristics with Eucharis are plesiomorphic, since its phylogenetic relationships are obscured by the large amount of unknown character state data. As in E. astrophiala, E. caucana, E. cor- ynandra, and E. lehmannii, this species exhibits a pattern of morphological novelty characteristic of peripheral isolation in Eucharis. 13.

Eucharis plicata is phenetically and cladisti- cally closest to E. castelnaeana. The phenetic re- lationship between the two species is most evident in E. plicata subsp. brevidentata, which in char- acteristics of the staminal cup and ovule number is intermediate between subsp. plicata and E. cas- telnaeana. From the latter, E. plicata may be distinguished by its wider leaves and tepals, larger flowers, campanulate staminal cup which is plicate along the filamental traces (Fig. 92E), more nu- merous ovules, and fruit and seed morphology typ- ical of subg.

Eucharis castelnaeana has been collected most frequently in the vicinity of Yurimaguas in Peru Volume 76, Number 1 Meerow 203 1989 Eucharis and Caliphruria (Fig. 91) and is sometimes locally abundant in rain Subgenus Euch ffini imis differt florib forest understory. It has the smallest flowers of any species in subg. Eucharis and is the major exception to the correlation of reduced flower size with loss of fragrance that otherwise characterizes Eucharis. Several living collections produce a mild lemon scent when ambient temperatures are high (as does E. plicata var. brevidentata). It is the only species of subg. Eucharis in which the ripe capsule is not leathery and orange. The glaucous, green, thin-walled capsule is tardily dehiscent and can abscise without opening, though the seeds with- in are fully ripe. Eucharis castelnaeana is autogamous. Under greenhouse cultivation it is the only species of Eucharis that successfully sets fruit with self-pol- len. Unmanipulated inflorescences regularly set 50- 75% of their capsules. Eucharis castelnaeana is variable in leaf and flower size (Fig. 93A) and, to a lesser extent, in androecial morphology. In his description of E. narcissiflora, Huber (1906) made reference to £. castelnaeana, described from the same location as Huber's type of E. narcissiflora, but differentiated his new species solely on the basis of size. The two taxa represent the extremes of size diversity of a single species and differ by no other characters. Populations represented by Schunke 14154a (Fig. 93Ai) have flowers almost twice as large as those of Schunke 14156 (Fig. 93Aii) but are otherwise indistinguishable. Shape of the staminal cup in the latter collection can range from nearly cylindrical to funnelform-c ylindrical. Eucharis plicata is phenetically the closest species to E. castelnaeana. Baillon (1894) consid- ered E. castelnaeana intermediate between Cali- phruria and Eucharis in his argument for com- bining these two genera. Baillon probably weighed flower size heavily in his judgment, one of only two characters by which E. castelnaeana resembles Caliphruria. In Baillon's time, most other small- flowered Eucharis species were not yet described. Additionally, the green, thin-walled capsule of £. castelnaeana is like the fruit of Caliphruria. Bail- lon (1894) gave no indication whether he was fa- miliar with the fruit of either Eucharis or Cali- hruria.

Meerow € Dehgan (1984a) re-established E. grandiflora (without hybrid des- ignation) as distinct from E. amazonica in Eucha- ris subg. Heterocharis. At the time, I considered E. lowii and E. mastersii to be distinct but closely related to E. x grandiflora. In 1984, I collected material in Colombia referable to E. lowii Baker and received living material of E. mastersii col- lected in Ecuador. According to Baker (1893), who described these two species from cultivated ma- terial, E. lowii had a staminal cup half as long as Volume 76, Number 1 1989 Meerow 205 Eucharis and Caliphruria LÀ URES 94- 98. rsit” form in Eonia, — 96.

When I compared the staminal cup of E. lowii with that of the lectotype of E. x gran- diflora, the synonymy of E. lowii with E. X gran- diflora became evident. The two seemed identical in all respects. Baker considered E. lowii to be a hybrid of E. mastersii and E. “grandiflora” and E. mastersii Baker (1885) to be a hybrid between E. sanderi and E. “grandiflora.” Baker distin- guished E. lowii from E. mastersii merely by the former's slightly longer-exserted staminal cup, which does not hold up.

X grandiflora appears intermediate in all respects to E. moorei and E. sanderi. Virtually all collec- tions of E. x grandiflora are from cultivated pop- ulations in Colombia and Ecuador according to specimen labels. Pollen stainability of either Co- lombian or Ecuadorean collections of E. x gran- diflora is never better than 10%, and I have not succeeded in obtaining seeds in cultivation with Eucharis either sibling pollen or pollen of other species.

Meerow & Dehgan (1984a) re-established Eu- charis amazonicas distinct from E. x grandiflora, a taxon with which it has been confused since its description by Planchon (1857). The species is indigenous only to Peru, in the upper and middle Huallaga valley, but is grown worldwide in tropical regions and may be sporadically adventive. The species has a somatic chromosome number of 2n — 68 (Meerow, 1987b; Nagalla, 1979) and is at least partially sterile. No specimen of E. amazon- ica, in contrast to most other species, has ever been collected in fruit; pollen stainability is only 50-65%; and viable seed has never been produced in cultivation. It is therefore conceivable that all populations of E. amazonica constitute a single clone. Its distribution throughout its narrow v range cultur- possibly extinct mutual ancestor. The morpholog- ical differences between these taxa are cryptic and virtually impossible to discern in most dried ma- terial without dissection of the ovary. Their close relationship is further supported by the presence of secondary vascular bundles in the petiole of both taxa, although much smaller in E. amazonica. DOUBTFUL OR EXCLUDED NAMES IN EUCHARIS Eucharis galanthoides hort., Linden, usually cited as E. galanthoides (Klotzsch) Linden (e.g., by aS 1936; Traub, 1963), Ann. Cat. Hort. 17: 4. 1862. This combination is based on the erroneous assumption that Linden's Kucharis ga- lanthoides was based on Mathieua galanthoides 59 (F, G, GH, 2 NY, S M Klotzsch (Meerow, 1987a). The actual basionym was Pancratium galanthoides, a name under which Linden received material of a Eucharis collected by Gustav Wallis in Amazonas. Mathieua galan- thoides was collected by Warscewicz in xeric, northwestern Peru (Warscewicz s.n., o type has been located for Linden's plant, and the name E. galanthoides merely appeared as a listing in his catalog. It is likely referable to E. castelnaeana (Baillon) Macbride. Eucharis himeroessa Sandwith ex Standley, Herbertia 3: 4. 1936. This name was never validly published with diagnosis or description.

Caliphruria subedentata is the most common and variable species of Caliphruria, at one time found throughout the moist lower and middle mon- tane forests of the slopes of the cordilleras Central and Occidental west of 76°W longitude (Fig. 105), and chiefly those surrounding the Cauca Valley. Much of this forest type has been destroyed in western Colombia so the species is no longer abun- dant. In the course of fieldwork in western Colombia in 1984, I was not able to find C. subedentata in its historical localities nor in the remnants of lower and middle montane forest that 1 explored. The species may yet persist in more inaccessible for- ested sites. Living material received from Mr. Thomas Fennell was said to have been collected in Ecuador, but this information is undocumented. At present, I have seen no Ecuadorean specimens of Caliphruria, nor encountered populations in the eld Within the range of C. subedentata, variation in leaf size, flower size, dentation of the androecium (Fig. 104C, D), and number of ovules is evident, but these patterns are for the most part continuous and/or mosaic in distribution, rendering recogni- tion of subspecific taxa inappropriate. Though Ba- ker (1877) characterized the species by the pres- ence of one or two small teeth between the free filaments, the flowers present on the type specimen of C. subedentata are completely edentate. Clono- typic material of the taxon described by Traub (1951) as E. fosteri is distinguishable from other living material of C. subedentata only by its slightly smaller leaves and flowers. 3.

It is readily distinguished by its hysteranthous leaves and the long teeth of the androecium which greatly exceed the short free filament (Fig. 104A). Unfortunately, C. tenera has not been re-collected since 1853. The hysteranthous leaves of this species suggest adaptation to drier habitats than usually charac- teristic of the genus.

Caliphruria korsakoffii is the only species of Caliphruria presently known outside of Colombia. In the size of the flower this species has affinity with C. tenera but can be distinguished by having evergreen leaves, subcylindrical tubes, and eden- tate, divergent, and longer stamens (Fig. 104E), coarser pollen exine reticulation, more numerous ovules, and higher altitudinal limits. The seeds of C. korsakoffii have a brown testa; those of C. subedentata are black. The ridged cuticle of the abaxial leaf surface of C. korsakoffii (Fig. 12) is quite different from the narrow cuticular striations C. subedentata (Fig. 11).

Microcarpium, which consists of 14 species distributed mainly in the southeastern United States, is the second-largest section in the genus, the largest being the phylogenetically central sect. Myrtocarpus of South merica. Plants of Ludwigia sect. Microcarpium are morphologically diverse; they form a polyploid complex of four diploids, eight intr two hexaploids, and one octoploi oid. They are facultatively autogamous herbaceous plants capable of reproducing both sexually and asexually (forming stolons late in the flowering season). Based on extensive crossing experiments as well as field and Reden studies, the relationships among species of this section iut been clarified. Internal genetic barriers iem species are nonexistent, and natural hybridization is fairly common. Among the diploid species, L. linifolia and L. linearis have very narrow leaves, petaliferous Add and elongate capsules. The two species, oweve r, differ chromosomally by one réim sall translocation. F, hybrids between them are vigorous, have ca. 50% sta huile pollen, and produce acces quantities of viable seeds. Ludwigia stricta, the Cuban endemic, is apparently most closely allied to L. linifolia, based on morphological evidence, but has not yet been studied biosystematically. udwigia microcarpa, in contrast, has spatulate-obovate leaves, small, apetalous owers, and minute obconical capsules. Artificial hybrids between L. microcarpa and either L. linearis or L. linifolia form neither stainable pollen nor seeds; for the most part, the chromosomes of War To do not pair in meiosis. crossed in any direction in the experimental ues and form fertile F, onn d Natural e in plants of this group are also fairly common and in some cases blur the boundaries of the species. Somewhat surprisingly, none of the extant diploid species are considered to be direct ancestors of the tetraploids, based on cytogenetic studies. The two hexaploid species, L. alata and L. simpsonii, are not closely related to each other. The affinity of L. lata is definitely with the tetraploid species group. Hybrids between L. alata and any other tetraploid species consistently exhibit a modal configuration of 16 II and 8 I in meiosis. Based on de morphology and the cytology of hybrids involving it, L. alata may have originated through hybridization between a tetraploid species, possibly L. lanceolata, and the diploid L. microcarpa, or populations ancestral to each of these Epa udwigia simpsonii, on the other hand, is closely related to L. curtissii, which is the only octoploid in sect. Microcarpium. The two species are unique in sect. Microcarpium in having loculicidal capsules and, together with the diploid L. microcarpa, in having spatulate-obovate cauline leaves. Cytogenetic and morphological studies suggest that the octoploid L. curtissii may have resulted from hybridization of L. s simpsonit and a petaliferous diploid species, possibly L. linifolia, L. linearis, or populations like them. Ludwigia microcarpa is involved in the formation of the hexaploid L. uS and ide ore that of the octoploid L. curtissii. The other progenitors of L. simpsonii are not clear, but some species in sect. Dantia or populations ancestral to them with apetalous FR T caite leaves, and a prostrate pem are likely andes ! This Pu was supported by the U. S.

Fossil records of pollen suggest that it is archaic and has existed at least 50 million years since the middle Eocene in both the Northern and Southern hemispheres (Gon- zales Guzmán, 1967; Rouse, 1962; Bratseva, 1969). Except for its chromosome structure and number, which appear to be relatively specialized (Kurabayashi et al., 1962), Ludwigia is one of the least specialized genera as to wood anatomy (Carlquist, 1975, 1982), floral anatomy (Eyde, 1977, 1978, 1981), and leaf anatomy (Keating, 1982). Based primarily on its unusual nectary po- sition, ovular vasculature, and independently de- rived epigyny, Eyde (1977, 1978, 1981) dem- onstrated that Ludwigia represents a distinct branch from the common ancestor of the family, with all other living genera on the other branch; in Hennigian terms, it is the sister group of the remainder of the family. The genus Ludwigia comprises 82 species that are diverse enough, especially in fruit, seed, and flower characters, to be classified in 23 sections, 14 of which are monotypic (Raven, 1963; Ra- mamoorthy & Zardini, 1987). Plants of Ludwigia are adapted to wet habitats in the tropics and subtropics. They probably originated in South America, the most important center of diversity for Ludwigia, and the area where the most prim- itive species are found (Ramamoorthy & Zardini, 1987). The genus, however, is also well represented in temperate North America and has three endemic species in temperate Asia. In North America, there are 23 native Lud- wigia species, characterized by having convex or elevated nectaries, tetramerous, haplostemonous flowers, pluriseriate ovaries, free seeds with narrow raphes, and herbaceous habits. Most of these plants are confined to the Atlantic and Gulf coastal plains of the United States, although some species are more widespread, and some extend into the islands of the Caribbean; one is endemic in Cuba. Based primarily on characters of capsules, mode of per- ennation, and phyllotaxy, the North American plants are classified into sect. Ludwigia (4 species), sect. Dantia (DC.) Munz (5 species), and sect. Micro- carpium Munz (14 species). Table 1 summarizes the diagnostic characters of these three sections. Based on his study of the structure and mor- phology of the capsules and nectaries of Ludwigia, Eyde (1981) considered sections Dantia and Mi- crocarpium to comprise a closely knit group de- rived from the phylogenetically central, diploste- monous Myrtocarpus complex, whereas sect. Ludwigia is different enough to have arisen in- dependently from the Myrtocarpus complex. Section Microcarpium was selected for the pres- ent revision because it is the second-largest section of Ludwigia and is very diverse, because it has not been revised in light of recent new data and evolutionary concepts, and because several species of this section are variable and taxonomically dif- ficult, with boundaries between species often blurred by intermediates. he purposes of this revision are to clarify species limits, to determine the degree and significance of natural hybridization, and to analyze natural affin- ities among species of sect. Microcarpium. Toward this end, more than 7,000 specimens from 44 herbaria have been consulted for morphological studies and for mapping. Furthermore, I have made three extensive field studies in the coastal plains of the southeastern United States. Searches for possible natural hybrids were made in the field whenever taxa occurred sympatrically. Seeds and/ or clonal transplants of all species were propagated at the Missouri Botanical Garden for chromosome determination and morphological study. TAXONOMIC HISTORY After the establishment of the genus Ludwigia in 1753 by Carl Linnaeus, the first group of North American species of sect. Microcarpium was dis- covered by the British botanist Thomas Walter (1788). Four of his species are currently recog- nized: L. glandulosa, L. linearis, L. pilosa (in- cluding L. rudis), and L. suffruticosa. Jean Baptiste A. P. M. de Lamarck (1789, 1792) published “Jussiaea brachycarpa” and “Ludwigia hirsuta," based on materials collected from South Carolina. These names are synonyms of L. glandulosa and L. pilosa respectively, as Lamarck himself suspected. The next botanist to study North American Lud- wigia was Andre Michaux (1803), who described nine species of Ludwigia in his Flora Boreali- Americana. Of these, L. microcarpa is a member of sect. Microcarpium In 1814, Jean L. M. Poiret correctly added the Volume 76, Number 1 1989 Peng Ludwigia sect. Microcarpium 223 TABLE 1. Comparison of the native North American sections of Ludwigia. Sect.

It was not until 1821 that the species of sect. Microcarpium were described by American bot- anists. Of the four species in sect. Microcarpium that Steven Elliott (1816-1821) described, Lud- wigia alata, L. sphaerocarpa, and L. lanceolata are currently recognized, whereas L. cylindrica represents a synonym of L. glandulosa Walter. Although Elliott correctly differentiated L. alata from L. lanceolata, the striking superficial resem- blance of the two species, especially in dried her- barium specimens, has constantly been a source of confusion among botanists (Long & Lakela, 1976; i dfrey & Wooten, 1981; Wunderlin, 1982; Clewell, 1985). The great dis- tinctiveness of these two species in such characters as floral morphology, pollen and seed surface fea- tures, and chromosome numbers were only appre- ciated recently (Peng, 1988, and this study). In 1836, Ludwigia polycarpa, a distinctive member of sect. Microcarpium distributed mainly in the northcentral United States, was discovered in Kentucky by Charles Wilkins Short and Robert eter. Shortly thereafter, John Torrey and Asa Gray (1838-1840), in A Flora of North America, pro- posed two varieties in sect. Microcarpium, i.e., Ludwigia cylindrica 8 brachycarpa and L. cap- itata B pubens. The former is currently recognized as the small-fruited, western subspecies of L. glan- dulosa (Peng, 1986), whereas the latter represents a natural hybrid between L. suffruticosa and L. pilosa (Peng, 1988). In 1845, George Engelmann and Asa Gray de- scribed a densely pubescent variety of Ludwigia linearis from Texas. Owing to the complex vari- ation pattern and the many intermediate popula- tions found in the range of this species, however, the variety is not recognized in the present study.

Microcarpium, became known when August Grisebach (1866) described /snardia stricta in Ca- talogus Plantarum Cubensium. The correct com- bination in Ludwigia was made by Francisco Adol- fo Sauvalle (1873) in the Flora Cubana. Alvin Wentworth Chapman added Ludwigia curtissii (1883) and L. simpsonii (1892) to the genus in his study of the flora of the southern United States. John Kunkel Small named Ludwigia simulata in 1903, not knowing that it represented the hybrid L. pilosa X L. lanceolata. In 1933, he grouped, for the first time, plants of Ludwigia sect. Micro- carpium under “Microcarpeae,” and described from the Everglades of Florida L. spathulifolia, which has now been merged with L. curtissii. Burghard Helwig in 1928 published Ludwigia cubensis from Cuba, which, however, is now con- sidered as conspecific with L. simpsonii from Flor- ida. Merritt Lyndon Fernald and Ludlow Griscom (1935) described three additional varieties for the highly polymorphic Ludwigia sphaerocarpa, which itself may have originated as a result of hybridiza- tion and which now intergrades with L. pilosa freely (Peng, 1988). These hybrids are not rec- ognized in this paper for reasons discussed else- where. Paul Munz's monograph (1944, 1965) con- tained the most comprehensive treatment of North American Ludwigia in his time. In the 1944 paper, he formally delimited sect. Microcarpium. His con- cept has since been widely accepted. James Allan Duke (1955) was the first author to indicate and to provide examples of natural hybridization among North American species of Ludwigia. In the course of my biosystematic study of Lud- wigia sect. Microcarpium, a number of atypical specimens initially identified as L. pilosa Walter were shown to be a new species, which I subse- quently named L. ravenii (Peng, 1984). This rep- resents the last named species of sect. Microcar- pium, and makes the total number of species of this section 14. MORPHOLOGY HABIT All species in Ludwigia sect. Microcarpium are erect perennial herbs ranging from about 15 to 100 cm tall. Leafy, usually unbranched stolons are produced from the base of erect stems. The stolons creep along the surface of moist ground or float on water late in the flowering/fruiting season. Some species, however, may also send out stolons in the summer while they are actively flowering or even throughout their growing season. The stolons can be long (up to 2.5 m) and stout as in L. pilosa or short (5-15[-20] cm) and slender as in L. micro- carpa and L. ravenii. The stolons give rise to erect shoots from their tips when the growing season resumes. In L. polycarpa the stolons are normally up to 15 cm long, and with leaves densely con- gested at the apex of stolons, overlapping one another and thereby protecting the apical meri- stem. This is apparently an adaptation to the severe winter that plants of L. polycarpa have to endure in the northern States. In L. suffruticosa stolons are uncommon. Instead, perennation is mainly by thick, somewhat woody, branched rhizomes. New shoots arise from the nodes of the rhizomes in growing season. It may be that in drier sandy situations, the plants persist by rhizomes, whereas in wet situations, the plants send out stolons. In Ludwigia curtissii and L. simpsonii, stolons are rarely formed; the plants simply produce new shoots, which are ascending or decumbent at first and soon become erect from the base of the pre- vious year's stem. They may not need to overwinter with low-profile stolons, as they are distributed mainly in Florida and the Caribbean Islands where the growing season is long and the winter is not severe. STEMS Stems are usually well branched in most species of Ludwigia sect. Microcarpium. Plants of L. suffruticosa are, however, often simple. When they . branch, the branches are few and usually arise from upper leaf axils beneath the compact inflo- rescences and characteristically overtop the main flowering/fruiting stems. Unbranched flowering stems are seen also in some populations of L. cur- tissii, L. linifolia, L. microcarpa, L. simpsonii, and L. stricta. The stems of some plants of L. microcarpa are distinctly zigzag. The stems of most species are slightly ridged; those of L. alata and L. microcarpa are often conspicuously ridged or winged. Ludwigia pilosa is the only species with nearly terete stems. The lower part of the stems of all species, when entirely submerged, is swollen and spongy. PUBESCENCE Many species in Ludwigia sect. Microcarpium are glabrous to subglabrous; the margins of leaf, sepal, or bracteoles, and surfaces of fruit may sometimes be minutely strigillose or minutely pa- pillose. Only L. ravenii and L. pilosa are consis- Volume 76, Number 1 1989 Peng 225 Ludwigia sect. Microcarpium tently hirtellous throughout. Ludwigia sphaero carpa, a species that intergrades substantially with L. pilosa, is variable in many aspects, especially pubescence. Populations of L. sphaerocarpa range from being completely glabrous to densely strigil- lose throughout. Similarly variable is L. linearis, but no interspecific hybridization has apparently played a role here. The pattern of the distribution of hairs in L. suffruticosa is especially interesting: some plants are completely glabrous; some plants are hirtellous either on the terminal inflorescence or on the basal stems (including stolons/rhizomes), or both, but are otherwise glabrous. The following are the main types of pubescence: l. Minutely puberulent. Hairs exceedingly short, fine, straight, erect to ascending, sparse or dense, 0.02-0.1 mm long, found occasionally in plants of Ludwigia linearis, L. sphaerocarpa, on fruits of L. microcarpa, and less commonly on fruits of L. simpsonii, L. curtissit, and L. suffru- ticosa. 2. Strigillose. cellular, 0.1—0.6 mm long, appressed to ascending; found in some populations of Ludwigia sphaero- carpa and L. linearis. 3. Minutely strigillose. Similar to strigillose pubescence, but the hairs more slender and shorter, ranging from 0.02 to 0.1 mm long. Frequently seen on sepals, bracteoles, and leaves of various species; also on the wings of capsules in Ludwigia lanceolata and capsules of both subspecies of L. glandulosa, and occasionally of L. polycarpa. Blunt-tipped, minute projections from the surface, ca. 0.02-0.03 mm in length. This hair type is found occasionally on the margins of leaves and sepals, on fruit walls, and on nectary discs. It may be difficult to distin- guish from minutely strigillose hair when the latter is exceedingly short. . Hirtellous. stiff, straight, erect to spreading, with an attenuate apex and a slightly broadened base, 0.25-0.95 mm long, translucent or spotted with light brown pigments. Hairs of this type are typical of Ludwigia pilosa, L. ravenii, and occasionally of L. sphaerocarpa, as well as part of the plant body of L. suffruticosa. Hairs coarse, translucent, uni- EN ~. 3 & ~ Sle S ms R Ta = e N D Hairs coarse, LEAVES The leaves are simple and alternate. Ludwigia simpsonii is exceptional in frequently having some opposite or subopposite leaves at the lower nodes or in the seedling stage, a feature that might be related to the derivation of one or more of its genomes from plants of the opposite-leaved sect. Dantia (see below). The leaves on the rhizomes of . suffruticosa are small and scalelike. Those on stolons are mostly elliptic- to rhombic-obovate or suborbicular (narrowly elliptic to narrowly oblan- ceolate in L. linearis and L. linifolia). These are usually broader and shorter than the cauline leaves, which are usually narrowly lanceolate to lanceolate, occasionally elliptic or oblanceolate, and often gradually reduced and narrower up the stem. Lud- wigia linearis and L. linifolia have sublinear leaves. In L. curtissii, L. microcarpa, and L. simpsonii, the leaves range from (narrowly) spatulate-oblan- ceolate to spatulate-obovate or spatulate. The leaves of all species of sect. Microcarpium are sessile or nearly so and either narrowly cuneate or attenuate basally. Ludwigia suffruticosa is ex- ceptional in having a rounded to obtuse leaf base. As in Ludwigia sect. Myrtocarpus sensu lato (Ramamoorthy & Zardini, 1987), the leaf margin is usually subentire, with a few glandular reddish or pink teeth that have an unusual hydathodal structure (Castells et al., 1979; Keating, 1982); such teeth are especially evident in L. microcarpa. The secondary veins of leaves are usually ob- scure adaxially and distinct abaxially in sect. Mi- crocarpium. In the closely allied Ludwigia lini- folia and L. stricta and in L. simpsonii and L. curtissii, the secondary veins are, however, faint on both sides of the leaves. Ludwigia linearis, having narrow leaves like the related L. linifolia, has, by contrast, on its abaxial leaf surface very evident secondary veins, which anastomose and form a pair of marginal veins along the margins. INFLORESCENCE The flowers are sessile or shortly pedicellate and borne singly in the (usually upper) leaf axils of the main stem and the branches. In Ludwigia suffru- ticosa, the flowers are congested in very compact terminal spikes or racemes. The leaves subtending the flowers are much reduced and bractlike. As stems of this species remain single or have only a few branches, there are only one to several such inflorescences per plant. In most other species, the stems are well branched, and the flowers are ax- illary and usually very abundant. In L. alata and L. pilosa, the flowers are sometimes quite con- gested on the upper parts of branches. In L. poly- carpa and L. glandulosa, one to a few very short branches heavily laden with flowers/ fruits are often seen from the very base of primary branches. This frequently gives an appearance of several flowering ranches arising simultaneously from the nodes of the main stem. 226 Annals of the Missouri Botanical Garden PEDICELS PETALS The flowers and fruits are nearly sessile in most species. Pedicels (measured from the base of ma- ture fruits), when present, are usually up to 0.5 (-1) mm long. Pedicels of Ludwigia suffruticosa and L. sphaerocarpa range 0.5-1.5(-2.3) mm long. Populations of L. linearis from west of the Mississippi River often have distinct pedicels up to 3.5(-5) mm long. BRACTEOLES Bracteoles are present in pairs near the base of the ovary in all species. They are succulent and are flanked by a pair of reddish or dark purplish, glandlike stipels on their base. A small swollen emergence located immediately below the bracteole is apparently an extension of the bracteole base and is prominent in some species, especially Lud- wigia curtissii, L. lanceolata, L. microcarpa, and L. simpsonii. This character is more evident in live plants than in herbarium specimens. Despite often being variable in length, even with- in the same plant (in Ludwigia linifolia, the brac- teoles range (1.5-)2.5-9(-13) mm long), a few species, including L. glandulosa, L. microcarpa, and L. sphaerocarpa, consistently have shorter bracteoles (less than 1.5 mm long) than those of the other species (Table 2). The bracteoles are located either at the base or higher up on the sides of the capsules. In L. sphaerocarpa and occa- sionally in L. glandulosa, L. linearis, and L. suf- fruticosa, however, the bracteoles are found on the short pedicels. FLOWERS Of the 15 taxa of sect. Microcarpium, only three diploid species are petaliferous, although ves- tigial petals may occasionally appear in a few flow- ers of polyploid species (Table 2). Flowers are con- sistently tetramerous, pentamerous flowers being exceptional. SEPALS Sepals are entire, but may be minutely strigillose along the margins in some species. Unlike plants of sect. Myrtocarpus sensu lato (Ramamoorthy & Zardini, 1987), the sepals persist even after the capsules mature and dehisce. Sepals are greenish in most species, but they are creamy white on the adaxial surface in L. alata, L. pilosa, and L. suffruticosa and are yellowish on the adaxial sur- face in L. sphaerocarpa. Petals are yellow, small, narrowly obovate to subrotund, and range from 2.5 to 6 mm long and from 1.2 to 5 mm wide. They fall off a few hours after anthesis, which occurs early in the morning, and are usually gone by noon. All petaliferous species are able to effect mechanical self-pollina- tion. My field experience, however, did not allow me to judge whether these plants attract signifi- cantly more insect pollinators than other apetalous species with showy sepals. STAMENS Most species of Ludwigia are consistently either haplostemonous (stamens in one whorl) or diploste- monous (stamens in two whorls) (Ramamoorthy & Zardini, 1987). All species of sect. Microcarpium are haplostemonous, which is a derived condition. The stamens are antesepalous, situated between the sepal base and the nectary discs. ANTHERS The anthers vary from 0.1 mm long in Lud- wigia microcarpa to 2 mm long in L. linearis. Ludwigia linearis is unique in sect. Microcarpium in having polysporangiate anthers partitioned hor- izontally by septa that include both tapetum and parenchyma (Tobe & Raven, 1986). Such spe- cialization is shared only by L. latifolia, an un- related South American species of sect. Tectiflora, and five other genera of Onagreae. It is worth noting, however, that these septa in the anthers disintegrate and result in a continuous sporogenous tissue before the anthers dehisce. Many conspic- uous vestiges of the disintegrated septa are visible on the inner surface of the anther wall at this stage. POLLEN The pollen of Ludwigia sect. Microcarpium is quite uniform, being characterized by isopolar grains frequently with prominent colpal extensions and with a psilate exine (Praglowski et al., 1983). Five species of sect. Microcarpium — L. alata, L. cur- tissit, L. microcarpa, L. simpsonii, and L. suf- fruticosa—shed their pollen singly, whereas the other nine species shed their pollen in tetrads (Table 2). This character is of some taxonomic value. For example, it can be used along with seed-surface pattern to distinguish L. alata, which sheds its pollen singly, from L. lanceolata, which sheds its pollen as tetrads. These two species are similar in general aspect and in their obpyramidal, winged 227 Volume 76, Number 1 1989 Peng Lud icrocarpium t.

DISCS One of the important characters that allows Lud- wigia to be recognized as the sister group to all other genera of Onagraceae is that its nectary disc is situated on the summit of the ovary. By contrast, all other onagraceous plants have nectaries at the base of the floral tube; the nectaries, therefore, are androecial (Eyde, 1981). The discs of Ludwigia sect. Microcarpium are shallowly dome-shaped, and they occur on the apex of the ovary. They are more or less distinctly four- lobed, the lobes alternating with the stamens, and re antepetalous (in petalous species). They are usually yellow or greenish at anthesis and turn dark reddish purple in fruit. In most species the discs are glabrous. Ludwigia pilosa is, however, usually hirtellous around the style base and between the disc lobes. Plants of L. sphaerocarpa are some- times hirtellous between the disc lobes, too. In densely strigillose populations of L. linearis, the nectary discs tend to be strigillose throughout or between the lobes also. In L. linifolia and L. stric- ta, the disc lobes are minutely papillose throughout, as are their fruit and seed surfaces. CAPSULES Characters of the capsules have been very useful to systematic and phylogenetic studies in Ludwigia (Small, 1933; Munz, 1942, 1944; Raven, 1963; Eyde, 1978; Ramamoorthy & Zardini, 1987).

Drawn from living plants cultivated at the Missouri Botanical Garden. wigia sect. Microcarpium (as ““Microcarpeae”), the mode of capsular dehiscence was one of the main criteria. Although his observations on cap- sular dehiscence were incomplete and not all species in this group have capsules dehiscing by the sep- aration of flaps from the Es of the nectary disc (see below), his concept taken up by Mun (1944, 1965) who ferially puse nd d. lished sect. Microcarpium. The shape, size, and pubescence of capsules are very diverse within sect. Microcarpium (Table 2, Figs. 1-15). Capsule shape ranges from obpyrami- dal to subcylindric, oblong-obovate, turbinate, or subglobose, and size ranges from 1 mm long in Ludwigia microcarpa to 12 mm long in L. linearis and L. linifolia. The surface vestiture ranges from glabrous to minutely papillose, strigillose, or hir- tellous. These characters have been extremely use- ful for identifying species and natural hybrids. Furthermore, in Ludwigia sect. Microcarpium, three patterns of capsular dehiscence are recog- nized (Peng & Tobe, 1987), each of which has a distinct anatomical basis: Ring dehiscence. The capsule dehisces along an apical “ring” as a result of the disintegration of thin-walled cells located between the nectary disc and the sepal base (Fig. 16). This pattern is exhibited by Ludwigia alata, L. lanceolata, L. linearis, L. microcarpa, and L. suffruticosa. lt was previously thought of as the only way capsules of Ludwigia sect. Microcarpium dehisced (Small, 1933; Munz, 1944; Raven, 1963). In these plants 230 Annals of the Missour f th i Botanical Garden Volume 76, Number 1 1989 Peng 231 Ludwigia sect. Microcarpium the zonation pattern in the capsule wall is relatively simple, consisting of the outer, enlarged paren- chymatous exocarp and the inner spongy endocarp. Peeled dehiscence. The capsule dehisces by the irregular rupture of the outer capsule wall (Fig. 17). This is exhibited by Ludwigia glandulosa, L. linifolia, L. pilosa, L. polycarpa, L. ravenii, L. sphaerocarpa, and L. stricta. These plants have a spongy mesocarp and an endocarp with conspic- uous inner hypodermis. When the seeds are dis- persed, they often carry along many hypodermal cells. Whether these cells are useful for the seeds to float awaits confirmatio Loculicidal delis The capsule dehisces by amd lone four longitudinally lenticular it h of the loculi (Fig. 18). Eventually the cansada is split into four basally united parts. This type of dehiscence is seen only in the closely related polyploids Ludwigia curtissii and L. simp- sonii. In these species, the zonation pattern of the fruit wall is basically similar to that of the “ring- dehiscent" species, except that the exocarp con sists only of the outer epidermis and a single-celled layer of outer hypodermis compactly aligned be- neath. These hypodermal cells are remarkably en- larged and radially elongate except along the me- dian longitudinal line facing each locule, where they are abruptly reduced or replaced by small, paren- chyma cells. It is exactly along these four lines that the capsules dehisce at maturity. To summarize, the fruit wall of all species of Ludwigia sect. Microcarpium is differentiated into a spongy zone (endocarp in ring-dehiscent and loc- ulicidally dehiscent species, or mesocarp in peeled- dehiscent species) and a continuous zone. As Eyde (1978) suggested, such differentiation undoubtedly aids seed dispersal by reducing the effective thick- ness and by the differential growth rate that could result in the separation of the outer layers from the inner. The specialized hypodermis in L. cur- tissil and L. simpsonii appears to represent a condition that has evolved a step beyond this point. SEEDS In all species of sect. Microcarpium, seeds have a narrow raphe and are free and pluriseriate in each locule of the capsule, with a narrow raphe. The seeds are small, from .7 mm long, and are cylindric, ellipsoid, reniform, or ovoid. They are mostly yellowish, light brown, or brown in color, although three species, Ludwigia linifo- lia, L. microcarpa, and L. stricta, nearly always have dark reddish seeds. Eyde (1978) was the first to point out that species of sect. Microcarpium are remarkably di- verse in surface cell orientation. Like capsule mor- phology, or rather together with capsule morphol- ogy, seed Eu [putem 1E ae excellent di gnosti c identifying the species and detecting natural hybrids. The seed surface cells are either subisodiametric or are elongate parallel or elongate transversely to the seed length, with minor variation on the two ends and areas near the raphe (Figs. 19-34). Although in different pop- ulations of both L. glandulosa and L. linearis the seed surface cells are oriented in two different ways, the pattern is not random. In L. glandulosa, the cells are elongate parallel to the seed length in subsp. glandulosa (Fig. 23) and transversely elon- gate in the western, short-fruited subsp. brachy- carpa (Fig. 24). Plants of L. linearis are extremely variable in pubescence, ranging from completely glabrous to densely strigillose. In general, seed sur- face pattern seems to be correlated with pubes- cence: subglabrous plants usually exhibit cells elon- gate parallel to the seed length (Fig. 21), whereas densely strigillose individuals generally have seed surface cells elongate transversely to the seed length ig. In Ludwigia sphaerocarpa the seed surface cells (Fig. 29) are not as regularly oriented as they are in the other species. They are arranged in columns both transversely elongate and parallel to the seed length, with the former alignment often dominant in the central part of the seed. Some = — FIGURES 19-34. (MO). — 20.

REPRODUCTIVE BIOLOGY All 14 species in Ludwigia sect. Microcarpium are genetically self-compatible perennials that re- produce sexually and vegetatively. About two-thirds of them are modally autogamous—a statistic com- parable to that for the whole genus (Raven, 1979). Shortly after the flowers open in the morning, the stigma becomes sticky and receptive and the sta- mens dehisce, exposing yellowish pollen entangled by the viscin threads. Initially the stamens are held away from the stigma and spread apart. The fila- ments, however, gradually arch toward the center and finally the anthers become firmly appressed to the sides of the sticky stigma in one to several hours (usually before noon), thus effecting self. pollination. This occurs in petaliferous as well a apetalous species, with the exceptions discussed in the following paragrap In Ludwigia alata, L. pilosa, L. suffruticosa, and many individuals of L. sphaerocarpa, the an- thers also bend toward the stigma at late anthesis, but the distance between the androecium and the gynoecium is such that self-pollination is impossible without the intervention of a pollen vector. In the first three, apetalous, species the sepals are con- spicuous and creamy within; in L. pilosa they are often tinged with pink along the main veins and the edges. Presumably these petaloid sepals serve to attract insect pollinators. In addition, these three species have yellowish discs that produce abundant nectar. Ludwigia sphaerocarpa, by contrast, has sepals that are yellowish within and very bright yellow discs that are more conspicuous than those of any other species, with the possible exception of L. linifolia (see below). Outcrossing in all four above-mentioned species is therefore not reinforced by protogyny/protandry or by male sterility, but merely by the physical separation of the stigma and the anthers. The self-incompatibility found in the more primitive members of Ludwigia sect. Myr tocarpus sensu lato is not present in sect. Microcarpium ectary discs are present in all species in sect. Microcarpium, but they vary in size and in the quantity of nectar produced. Ludwigia microcar- pa. an apetalous species with tiny flowers (the ovary is less than 1 mm long), has a nearly flat, greenish disc that produces very little nectar, and is presumably highly autogamous. Despite this, the fact that several natural hybrids—e.g., L. micro- carpa X L. curtissii and L. microcarpa X L. simpsonii, and an intersectional hybrid, L. micro- carpa X L. palustris (n — 8; sect. Dantia)— were collected in the field where the parental species grow sympatrically (see below) suggests that insect pollinators do occasionally visit plants with minute, inconspicuous flowers. Living plants from two of the three petaliferous species were available for observation; Ludwigia stricta, endemic in Cuba, has not been studied as a living plant. Flowers of L. linifolia have very conspicuous nectary discs that produce copious nectar. This, along with the yellow petals, serves to make the flowers highly attractive to insects. Ludwigia linearis has a comparatively shallow ovary disc that secretes less nectar. This species is noteworthy in sharing with the unrelated South American L. latifolia (Benth.) Hara (sect. Tecti- flora) the distinction of being the only members of the genus Ludwigia in which the sporogenous tis- sue of the anthers is divided into packets horizon- tally by both tapetum and parenchyma (Eyde, 1977; Tobe & Raven, 1986). This character is also shared by five other genera of Onagraceae, as mentioned previously. Paper wasps of the genus Polistes have been observed to visit flowers of species of Ludwigia sect. Microcarpium grown in the netted experi- mental greenhouse at the Missouri Botanical Gar- den. In the field, more insects (usually oed honeybees, and wasps) were attracted to L. pilo and, less so, to L. sphaerocarpa. Moths and ants have also been observed visiting L. pilosa. Rela- tively few field observations of insect pollinations on other species have been made in my trips to the southeastern United States. Circumstantial evi- dence from the presence of abundant natural hy- brid populations suggests that insect pollination must be more common than I have observed. In addition to sexual reproduction, nearly all species of Ludwigia sect. Microcarpium produce sprawling stolons at the base of the erect, flowering stems late in their flowering season. This vegetative reproduction enables the plants to overwinter, when the erect stems die back; in spring, they can then produce a large colony before other species can invade. Some of the sterile populations of natural hybrids also persist by this means. In £. suffruti- cosa, however, stolons are not as common as un- derground rhizomes. In L. curtissii and L. simp- sonii, stolons are not apparent. These plants simply form new shoots from the lower nodes of the died- back stem of the previous year. These shoots are decumbent or ascending initially, but soon become erect. Volume 76, Number 1 1989 Peng 233 Ludwigia sect. Microcarpium CYTOLOGY Chromosomes of Ludwigia are the smallest in the Onagraceae, and they may differ conspicuously in size within a single genome. The proximal ends of the chromosomes are heavily pycnotic and ap- pear in interphase nuclei as very distinct and def- inite chromocenters (Kurabayashi et al., 1962). The basic chromosome number of the genus is x = 8, with no aneuploidy but extensive polyploidy (Raven & Tai, 1979). Through the efforts of Greg- ory & Klein (1960), Kurabayashi et al. (1962), Raven & Tai (1979), and Peng (1984, 1988), the chromosome numbers of all species of Ludwigia sect. Microcarpium have been established. There are four diploid species with n = 8 (L. linearis, L. linifolia, L. microcarpa, and L. stricta), eight tetraploid taxa with n — 16 (L. glandulosa subsp. glandulosa, L. glandulosa subsp. brachycarpa, L. lanceolata, L. pilosa, L. polycarpa, L. ravenii, L. sphaerocarpa, and L. suffruticosa), two hexa- ploid members with n — 24 (L. alata and L. simp- sonii), and an octoploid with n — 32 (L. curtissii). For a review and discussions see Peng (1988). EcoLoGY AND GEOGRAPHICAL DISTRIBUTION With the exceptions of Ludwigia stricta, which is endemic to Cuba, and L. polycarpa, which is distributed mainly in the northcentral United States, Ludwigia sect. Microcarpium is confined primar- ily to the Coastal Plain of the southeastern United States. Several species also extend further south or east: L. alata to Jamaica; L. curtissii to the Bahamas; and L. linifolia disjunct to Tabasco, Mexico. Ludwigia simpsonii occurs in Cuba and Jamaica, and L. microcarpa in the Bahamas, Cuba, and Jamaica. Ludwigia stricta is exceptional in being endemic to Cuba. A detailed description of the ranges with maps for each species is given in the taxonomic treatment. Like Ludwigia species occurring in other parts of the world, plants of Ludwigia sect. Microcar- pium grow in wet habitats. They are commonly found along alluvial ground or in the shallow water of many areas, including ponds, lakes, streams, lagoons, sloughs, backwaters, swales, wet rivers, meadows or prairies, open swamp forests, drain- ages, and irrigation ditches. All species grow in sandy or occasionally peaty soils. A few species grow in brackish marsh or tidal flats (L. alata, L. linifolia, L. microcarpa, and L. simpsonii), in sinks in limestone prairies (L. alata, L. curtissii, L. microcarpa, L. simpsonii, L. sphaerocarpa, and L. suffruticosa), and in clay soils (both sub- species of L. glandulosa). None of the species in Ludwigia sect. Microcarpium exhibit the aggres- siveness characteristic of weedy plants, although the following taxa have rarely been observed grow- ing in disturbed habitats: L. linearis, L. micro- carpa, L. simpsonii, and both subspecies of L. glandulosa. EXPERIMENTAL HYBRIDIZATION Results from the extensive artificial hybridiza- tion among members of Ludwigia sect. Micro- carpium (Peng, 1988) are summarized as follows. l. There is generally little difficulty in obtaining hybrids between members of sect. Microcar- pium; most F, plants grow to maturity, and many set abundant seeds. Hybrids between plants of the same ploidy level are generally intermediate in morphology; hybrids between plants of different ploidy levels tend to be more similar to the parent with the higher chromo- some number. Character such as capsule shape and size, bracteole length, overall pubescence, presence or absence of petals, seed surface pat- tern, and pollen stainability are very useful in distinguishing species and identifying hybrids. . All diploid species can be crossed with one another and form floriferous F, plants. Hybrids N between the petaliferous diploids with narrow leaves (Ludwigia linearis and L. linifolia) are vigorous, have ca. 50% stainable pollen, and produce a moderate amount of viable seeds. A modal meiotic configuration of a ring or chain of four plus six bivalents are frequently ob- served in reciprocal F, hybrids. Hybrids be- tween either of the petaliferous diploids and the apetalous, diploid L. microcarpa are, in con- trast, highly sterile as to pollen and seed set. Nearly all chromosomes remain unpaired in meiosis in these hybrids. . All eight tetraploid members studied are inter- o2 fertile: chromosome pairing in meiosis is nearly complete, and pollen stainability and seed set are high in hybrids between any two tetraploid species, no matter how different they are from each other morphologically. 4. Although the two hexaploid (n — 24) species, Ludwigia alata and L. simpsonii, can crossed and produce agb 3 18> meiosis is irregular with ak The affinity of L. alata is apparentlk with species of the tetraploid group, based on morphological characters. Hybrids between L. alata and any tetraploid species are easily obtained. They pro- uce moderate seed set and have 43-71% stainable pollen. Meiosis in these F, individuals 234 Annals of the Missouri Botanical Garden typically exhibited a maximum of 16 bivalents and eight unpaired chromosomes. By contrast, the hexaploid Ludwigia simpsonii (n — 24) is clearly allied to the octoploid L. curtissii (n — 32). Hybrids between them are highly fertile, having 80-90% stainable pollen and producing good seed set. These plants consistently exhib- ited a meiotic configuration of 24 bivalents and eight unpaired chromosomes. Seeds obtained from crossing species of any two of the following groups, (1) tetraploid species group (including the allied Ludwigia alata), (2) diploid species, and (3) L. curtissii and L. simp- sonii, often failed to germinate. Those that ger- minate may either be inviable or produce flow- ers that set negligible or no seed and tend to D have very low levels of stainable pollen. For a complete discussion of the experimental hy- brids, consult Peng (1988). NATURAL HYBRIDIZATION Experimental hybridization (Peng, 1988) re- vealed that vigorous and floriferous hybrids can readily be obtained between most members of Lud- wigia sect. Microcarpium. The general lack of postzygotic barriers and the facts that all species in this section are perennial and that most of them are sympatric, have similar preference for habitats, flower in the morning during the same season, are facultatively outcrossing, and have similar kinds of indiscriminate insect pollinators, strongly suggest that natural hybrids should be fairly common in the field. Field observations and herbarium study show that hybrid populations of Ludwigia sect. Micro- carpium are indeed abundant. Except for this and the companion paper (Peng, 1988), however, very little has been reported about the natural hybrid populations of sect. Microcarpium. The variation patterns generated by the intergradation among some members of sect. Microcarpium have pre- viously been detected by Torrey & Gray (1840) and Small (1903); such plants were given names at varietal and specific rank respectively, but no indication of their hybrid origins was mentioned. Torrey & Gray (1840) described L. capitata B pubens from a population of L. suffruticosa X L. pilosa from Georgia; Small (1903) applied the name L. simulata to a population of L. pilosa x L. lanceolata from North Carolina. Duke (1955) was the first to point out that some Ludwigia species show varying degrees and pat- terns of intergradation in North Carolina. In his informative study, he compared the morphological characters of a mixed population consisting of plants of L. pilosa, L. glandulosa, and the intermediates, and considered the latter as possible hybrids. Upon examination of his voucher collections, it is con- firmed beyond doubt that these plants represent uniform F, hybrids of L. pilosa x L. glandulosa. Duke (1955) further suggested that “‘self-pollina- tion is the rule in this genus, and that cross-polli- nation is a very rare exception to the rule," and speculated that phyllophagous insect caterpillars may have brought about cross-pollination while for- aging leaves. This, however, is not true, as at least four species in sect. Microcarpium have somewhat showy sepals and produce copious nectar and re- quire insect vectors to pollinate their flowers to set seeds. Such insects as bumblebees, wasps, honey- bees, moths, and even ants have frequently been seen obtaining nectar on the flowers of Ludwigia sect. Microcarpium. In a biosystematic study of Ludwigia sect. Dan- tia, a close ally of sect. Microcarpium with op- posite leaves and prostrate habit, Schmidt (1967) reported two intersectional hybrids, L. repens X L. simpsonii (as L. repens X L. curtissii) and L. palustris X L. glandulosa from North Carolina and Florida, respectively. His observations of the hybrid between L. palustris (n = 8; sect. Dantia) and L. glandulosa (n = 16; sect. Microcarpium) revealed very little association between chromo- somes, with 0-3 weakly joined bivalents in meiosis. The other natural hybrid, involving L. repens (n — 24; sect. Dantia) and L. simpsonii (n — 24; sect. Mesa. yielded 48 unpaired chro- mosomes at mesiosis, suggesting the dissimilarity in the genomes of plants in the two North American sections. Observation of individuals exhibiting a combi- nation of characters intermediate between distinct taxa initially suggests natural hybridization. Mem- bers of the following species pairs, Ludwigia alata (n — 24) and L. lanceolata (n = 16), L. pilosa (n = 16) and L. ravenii (n = 16), and L. simpsonii (n = 24) and L. curtissii (n = 32), however, are usually so similar in appearance, especially in dried herbarium specimens, that their hybrids cannot be recognized readily. esults from experimental hybridization suggest that capsule shape and size are the most important diagnostic characters for detecting hybrids in sect. Microcarpium. Other useful features include over- all pubescence, seed surface cell shape and ori- entation, the presence or absence of petals, whether pollen grains are shed singly vs. in tetrads, and pollen stainability. Seed surface pattern is useful only for the determination of hybrids in the tet- Volume 76, Number 1 1989 Peng 235 Ludwigia sect. Microcarpium raploid group (including Ludwigia alata), as these nine taxa are interfertile, yield abundant seeds, and are diverse with respect to this character. Absence of developing fruits and low levels of pollen stain- ability, however, are characteristic of hybrids re- sulting from all other heteroploid crosses, with the exception of L. curtissii (n = 32) x L. simpsonii — 24). As a last resort, chromosome number and meiotic chromosome behavior are useful in- dicators of natural hybrids when the parents in- volved have different chromosome numbers or dif- ferentiated genomes. The natural hybrid populations mentioned below are discussed dnd poetas the treatment of the species in t tion. Full citation of these specimens of hissed is given in the com- panion paper (Peng, 1988). ield experience indicates that natural hybrid populations are fairly common wherever two or more species grow side by side. A total of 15 intrasectional hybrids and seven intersectional (among plants of sects. Microcarpium and Dantia) hybrids are recognized (Peng, 1988). Hybrids re- sulting from crosses among members of the tet- raploid species group (including Ludwigia alata) are by far the most common. The following hybrid combinations are representative: L. alata X L. pilosa (four populations from Florida, one from Georgia, and one from Mississippi), L. alata x L. suffruticosa (seven populations from Florida), L. glandulosa subsp. glandulosa X L. glandulosa subsp. brachycarpa (one from Oklahoma and one from Texas), L. glandulosa subsp. glandulosa x L. pilosa (two from North Carolina, one from Geor- gia, one from Alabama, and two from Mississippi), L. glandulosa subsp. glandulosa X L. sphaero- carpa (one from South Carolina, one from Mis- souri), L. lanceolata X L. pilosa (three populations from Florida), L. lanceolata x L. suffruticosa (two from Florida), L. pilosa x L. sphaerocarpa (many populations from North Carolina, South Carolina, Georgia, Florida, Alabama, and Texas), L. pilosa X L. suffruticosa (two from North Carolina, three from Georgia, and two from Florida), and L. poly- carpa X L. sphaerocarpa (two populations from Indiana). Backcrossed generations or segregates of advanced generations are found of L. lanceolata X L. suffruticosa, L. pilosa X L. suffruticosa, and most abundantly of L. pilosa X L. sphaero- carpa. As in the case of artificial hybridization, the tetraploid hybrids are highly fertile as to seed and pollen; hybrids between the hexaploid Ludwigia alata and the tetraploid species have slightly lower levels of stainable pollen and seed set. It is note- worthy that in nearly all of the above hybrids at least one member of p pur of putative parents is unable to und If-pollination has somewhat qmm sepals. In other words, L. alata, L. pilosa, L. sphaerocarpa, and L. suffru- ticosa hybridize more frequently than other tet- raploid species that are modally autogamous. Sporadic occurrence of sterile triploid hybrids 16) x L. lin- earis (n — 8) (one population from North Carolina and the other from Georgia) and L. sphaerocarpa (n = 16) x L. linearis (one population from Al- abama). One probably diploid hybrid population of L. linearis X L. linifolia was collected from Flor- ida in 1981. Attempts to re-collect and to study live plants of this hybrid have failed, because the habitat was destroyed (Popenoe, pers. comm.). Hybrids between Ludwigia curtissii (n = 32) and L. simpsonii (n — 24) very probably occur in the field but would be difficult to detect. Ludwigia curtissii hybridizes with L. linifolia (n = 8) and include Ludwigia glandulosa (n — with L. microcarpa (n — 8) to form sterile hybrids. At least four populations of L. simpsonii X L. microcarpa are known from Florida. It is of in- terest to note that among the putative parental species here concerned, only L. linifolia has some- what showy petals and produces copious nectar, whereas all other species are probably modally autogamous. Hybrids involving putative parents from sect. Microcarpium and sect. Dantia are also not un- common. Ludwigia repens (n — 24; sect. Dantia) hybridizes with L. simpsonii (n — 24) and L. cur- tissii (n = 32) in Florida. At least eight such populations are known, all producing flowers, but the ovaries abort after mechanical self-pollination. Ludwigia palustris (n = 8; sect. Dantia), a wide- spread and apparently autogamous species, hy- bridizes with L. glandulosa subsp. glandulosa (n — 16) and forms sterile hybrid populations in Vir- ginia (one population). It also hybridizes with the diploid, small-flowered and presumably autogamous L. microcarpa of sect. Microcarpium and forms sterile hybrids in North Carolina (one population), Georgia (one population), and Florida (three pop- ulations). In Kentucky, L. palustris hybridizes with L. polycarpa (n — 16) and likewise forms sterile hybrids. The only intersectional tetraploid hybrid is known from a single population of Ludwigia arcuata (n — 16; sect. Dantia) X L. pilosa (n — 16) collected from Alabama. Flowers of both putative parents are showy and attract many insect pollinators. Es- tablished hybrids, however, are very rare in nature.

Such hybrids synthesized in the experimental greenhouse showed a remarkably high level of chromosome pairing (ca. 12-15 bivalents and 2- 8 unpaired univalents; 1 or 2 trivalents occasionally seen) but had only 38% stainable pollen. Not a single seed was set despite many attempts at ar- tificial self-pollination (like L. pilosa, this hybrid cannot undergo mechanical self-pollination). o summarize, geographical isolation and self- pollination are the primary factors limiting natural sect. Mi- crocarpium. For example, L. polycarpa occurs in the central Midwest (Fig. 45), where it is isolated geographically from all other species of sect. Mi- crocarpium except L. sphaerocarpa. Where the hybridization among species of Ludwigia two species come into contact, hybridization oc- curs. Ludwigia microcarpa, an extreme selfer, has been hybridized successfully with most species of sect. Microcarpium in the greenhouse, and the resulting hybrids were vigorous. Ludwigia micro- carpa grows sympatrically with many other species, but natural hybrids have been found only with £. simpsonii, L. curtissii, and some members of sect. Dantia. In general, natural hybrids are usually frequent wherever two species occur together. This is par- ticularly true for plants in the tetraploid group, hybrids of which were often found intermixed with utative parents. The sorts of disturbed habitats suggested by Anderson (1948) do not appear to be necessary for the establishment of natural hy- rids in Ludwigia sect. Microcarpium As outlined above, natural hybridization is not limited to species within Ludwigia sect. Micro- carpium. At least seven hybrid combinations, some of which occur commonly in nature, have been found between members of sect. Microcarpium and sect. Dantia. Most of these have also been synthesized in the experimental greenhouse. None Volume 76, Number 1 1989 Peng 237 Ludwigia sect. Microcarpium of the intersectional hybrids set viable seeds, al- though they are usually very vigorous and appear to compete well with their parents. Once estab- lished, these sterile hybrids may be able to persist in a given location due to their perennial habit. Furthermore, new colonies may be established veg- etatively if entire plants or fragments are trans- ported to suitable habitats, most likely by water. EVOLUTIONARY RELATIONSHIPS Ludwigia sect. Microcarpium consists of four diploids, eight tetraploids, two hexaploids, and one octoploid. Ludwigia microcarpa is distinct among the di loid species by the more or less spatulate cauline leaves and small, inconspicuous, apetalous flowers; and it is modally self-pollinated. All three other diploid species, L. linearis, L. linifolius, and stricta, have elongate, narrow leaves and relatively showy, petaliferous flowers and are facultatively outcrossing. The divergence of L. microcarpa from the rest of the diploids is further demonstrated by the cytogenetic study of artificial hybrids in this group. Artificial F, hybrids between L. microcarpa and either L. linearis or L. linifolia were com pletely sterile; in meiosis they revealed very few chromosome associations, with 0-3 weakly joined bivalents. Ludwigia linearis is unusual in sharing with the unrelated South American species L. latifolia (Benth.) Hara (sect. Tectiflora) the character of polysporangiate anthers in which the locules are divided by transverse septa composed of tapetum and parenchyma. Otherwise, L. linearis is appar- ently somewhat related to L. linifolia. The two species differ chromosomally by at least one recip- rocal translocation. F, hybrids between them have ca. 50% stainable pollen, and they produce mod- erate quantities of viable seeds. Ludwigia stricta, which is endemic to Cuba, is more closely related to L. linifolia than to any other species in sect. Microcarpium. It differs from L. linifolia only by the broader leaves, smaller floral parts, and shorter fruits (Table 3). The cross- ing relationships of L. stricta with other diploid species are currently being investigated. The eight tetraploid taxa (n — 16) are uniformly apetalous and are otherwise remarkably diverse in overall pubescence, shape and color of sepals, shape and dehiscence of capsules, bracteole length, seed surface cell pattern, and whether pollen is shed singly or as tetrads. Correlations in these features, however, are evidently nonexistent. It is therefore of great interest to find that these eight morpho- logically well-delimited taxa can be crossed in any combination and produce vigorous and fertile off- spring. The hybrids exhibit nearly complete chro- mosome pairing and high levels of stainable pollen. Natural hybridization among plants of this group is abundant, especially among those members with somewhat showy sepals. Most natural hybrids are F, plants that occur in more or less undisturbed habitats where the putative parents also grow. In- trogressed populations or segregates of advanced generation of Ludwigia pilosa X L. sphaerocarpa hybrids, however, are also abundant and wide- spread. Cytogenetic studies of experimental hybrids between the tetraploid species and the diploid species suggest that no extant diploids are believed to have been involved piani in the formation of the tet- e species grou udwigia alata, a piba (n = 24) species, fet the tetraploids morphologically. Super- ficially it is most similar to L. lanceolata in general aspect and especially in the characters of winged capsules. Nearly all of the reciprocal hybrids be- tween the hexaploid L. alata and any of the tet- raploid species exhibited a modal meiotic config- uration of 16 bivalents and 8 univalents, which suggests that they share two genomes in common. Judged from the morphology of the hexaploid and from the pairing of chromosomes in experimental hybrids, L. alata probably originated following hy- bridization between one of the tetraploids, perhaps L. lanceolata, and the diploid L. microcarpa, or populations ancestral to them. The affinity of the other hexaploid, Ludwigia simpsonii, however, is definitely with L. curtissit, the only octoploid in sect. Microc | wid These two species are unique in having and in having, along with the diploid L. microcar- a, more or less spatulate cauline leaves. Ludwigia curtissii and L. simpsonii are polymorphic and are sometimes difficult to distinguish morphologi- cally. Cytogenetic data suggest that the hexaploid chromosome complement of L. simpsonii includes three different genomes, one of which is identical with that of L. microcarpa. Artificial hybrids be- tween L. simpsonii and L. curtissii exhibited a meiotic configuration of 24 bivalents and eight univalents, which suggests that these two closely related species possess three genomes in common. Based on morphological characters and crossing relationships, the octoploid L. curtissii was prob- ably derived following hybridization between a pe- taliferous, narrow-leaved diploid lineage similar to L. linifolia and the hexaploid L. simpsonil. o summarize, following the differentiation of diploid species of Ludwigia sect. Microcarpium, some diploids have evidently become extinct. Nat- ural hybridization among the diploid lineages fol- 238 Annals of the Missouri Botanical Garden lowed by polyploidy has played a major role in the evolution of this group. Postzygotic genetic barriers do not separate most of the species of this section. Rather, the major limiting factor to natural hy- bridization appears to be the modally autogamous breeding system of most species. Geographical iso- lation is important only with respect to L. poly- carpa, which is distributed well to the north of nearly all the other taxa. Natural hybridization is prevalent within Lud- wigia sect. Microcarpium, and hybrids often grow intermixed with putative parental populations. All interploid hybrids are completely sterile except for alata (n — 24) and the tetra- ploid species (n = 16), and crosses between L. curtissii (n = 32) and L. simpsonii (n = 24). Even sterile hybrids, however, can persist and form large colonies, at least locally, by means of strong veg- etative reproduction via stolons. Natural hybrids are especially common among members of the tetraploid group (including Lud- wigia alata) and are nearly always vigorous and fertile. Especially complex is the pattern of vari- ation in the tetraploid L. sphaerocarpa, which is apparently comprised largely of widespread stabi- lized hybrid populations that exhibit a combination of characters distinguishing them from other taxa. As in the evolution of Epilobium in New Zealand (Raven & Raven, 1976), the recombination of genetic information from somewhat differentiated crosses between L. populations followed by the maintenance of well adapted genetic strains by a combination of autog- amy and vegetative reproduction appears to have played a central role in the evolution of the poly- ploid members of Ludwigia sect.

Plants of L. linifolia are often found in drainage ditches, along margins of creeks or swamps, on bottom meadow, on open edges of cypress swamps, in moist pineland, and along edges of brackish lakes. Ludwigia linifolia ranges along the Atlantic coast from extreme southeastern North Carolina and eastern South Carolina through south- ern Georgia and peninsular Florida. To the west, its range extends through the Florida panhandle, to extreme southern Alabama and Mississippi. A disjunct population has been collected in north- central North Carolina (Fig. 36). It is also known from a disjunct population at Huimanguillo, Ta- basco, Mexico, on the Yucatán PORE. Flow- ering from late June through October; fruiting from July through November.

Its variability chiefly affects the size of the capsules and the lengths of the bracteoles, which are at- tached to the sides of the capsule. Its closest affinity is definitely with L. stricta, a Cuban endemic, from which L. linifolia differs by having narrower leaves, larger floral parts (including sepals, anthers, fila- ments, and style), and longer fruits and bracteoles. Characters of the two species and the only other petaliferous member of the section, L. linearis, are listed for comparison in Table Ludwigia linifolia has somewhat showy petals and the most prominent nectary disc lobes occur- ring in sect. Microcarpium. The nectary disc is bright yellow and produces copious nectar at an- thesis. Herbarium specimens often reveal empt anthers held away from the stigma (mechanical self-pollination has not occurred yet). This obser- vation suggests that L. linifolia is probably modally outcrossing, which is corroborated by limited field observations. Ludwigia linifolia occurs with L. alata, L. cur- tissii, L. glandulosa, L. linearis, L. microcarpa, and L. pilosa in the field. Natural hybrid popu- lations have, however, been found only between L. linifolia (n = 8) and L. i is contrary to what one would expect for the out- curtissii (n = 32). This crossing L. linifolia. However, experimental hy- bridizations (Peng, 1988) indicate that artificial hybrids between the diploid L. linifolia and plants of any other ploidy level in sect. Microcarpium are generally difficult to obtain. Repeated trials with different parental strains were successful in some cases, but the resulting hybrids were usually weak and needed special attention to reach flowering stage. Attempts to synthesize the natural hybrid L. linifolia X L. curtissii in the experimental green- house were unsuccessful. 2. Ludwigia stricta (Wright ex Griseb.) Wright in Wright & Sauvalle, Fl.

Ludwigia stricta has a close affinity with L. linifolia, which is distributed in the southeastern United States and occurs on the Yucatán Peninsula in Tabasco, Mexico. Both are diploids; they are similar in stature, have four petals, shed their pollen as tight tetrads, have subcylindric capsules that dehisce irregularly from the sides, and have reddish brown seeds with subisodiametric surface cells.

The variation pattern of Ludwigia linearis is highly complicated as a result of a great deal of intergradation among slightly differentiated geo- graphical races. I have classified the varied pop- ulations into four categories: 1) the subglabrous morph, 2) the densely strigillose morph, 3) the completely glabrous morph, and 4) the interme- diate morph, which is discussed below. 1. Subglabrous morph. Stems sparingly mi- nutely strigillose. Cauline leaves glabrous except for the minutely strigillose margin. Sepals 2.3-4 (-4.5) mm long, 1.3-2.4(-3) mm wide, the apex acuminate, minutely scaly strigillose abaxially. An- thers 1.1- ong, the filaments 1.3-1.8 (-2.1) mm long. Nectary disc minutely scaly strig- illose around margins of the lobes. Style (0.4—)0.7— 0.9(-1.2) mm long, glabrous. Stigma (0.6-)1-1.5 mm long. Capsules densely minutely scaly strigil- lose, 5-8.5(-10) mm long, 2-4(-5) mm thick, sessile or with a constricted, pedicel-like base. Brac- teoles 0.4-1.6(-2.5) mm long. Seed surface cells columnar, elongate parallel to the seed length. The type of Ludwigia linearis Walter belongs to this morph. Plants of this sort are distributed along the Atlantic coast from southern New Jersey through Delaware, eastern Maryland, eastern Vir- ginia, eastern halves of North Carolina and South Carolina, and Georgia, to their southern limit in the central Florida peninsula. They extend west- ward through the panhandle of Florida and across Alabama and southern Mississippi, reaching east- ern Louisiana (Washington and St. Tammany par- ishes only). Northward, they occur throughout the eastern half of Alabama and extend to central Tennessee. Stems and leaves densely minutely strigillose to puberulent in some cases. Sepals 3-5 mm long, 1.5-2.5(-3.5) mm wide, the apex cuspidate or elongate-acumi- nate, minutely strigillose or puberulent abaxially. Anthers (1.1-)1.3-2 mm long, the filaments (1.2-)1.5-2(-2.2) mm long. Nectary disc minutely scaly strigillose throughout or only surrounding margins of the lobes. Style (0.6-)0.9—1.5 mm long, glabrous to densely strigillose, especially on the lower part. Stigma (1-)1.3-1.9 mm long. Capsules densely minutely strigillose or puberulent, 5-10 (-12) mm long, 3-5.5 mm thick, the base sessile 2. Densely strigillose morph. Volume 76, Number 1 1989 Peng 251 Ludwigia sect. Microcarpium or with distinct pedicels up to 5 mm long. Brac- teoles 0. .5) mm long. Seed surface cells columnar, pane transversely to the seed length. Plants of this morph were recognized at varietal rank, Ludwigia linearis var. puberula, by gelmann & Gray (1845). They occur most fre- quently in central and southern Arkansas, western Louisiana, and the eastern half of Texas. Scattered populations, however, occur east of the Mississippi River in eastern Louisiana and southern Mississip- pi. A single population was found in Dallas County in southcentral Alabama. In addition to being much more pubescent than plants of the subglabrous morph, plants of the densely strigillose morph are slightly larger in the size of most floral parts. Furthermore, their seed surface cell pattern is different from that of the subglabrous morph. The cells are elongate parallel to the seed length in the subglabrous morph but are elongate transversely to the seed length in the densely strigillose morph. 3. Completely glabrous morph. Characters of this morph are exactly the same as those of the densely strigillose morph, except that the former is glabrous throughout. Indeed, many plants of the completely glabrous morph were collected along with those of the densely strigillose morph. Ex- amples are as follows: U.S.A. ARKANSAS: Prairie Co., low moist areas in rice paddies, P. O. Hazen, Demaree 37904 e AL gla- brous morph: TEX, VDB-22422, VDB-4 5; mixed collection of both the completely glabrous xe and the densely strigillose morph: e 3 t “of completely glabrous morph and the densely erige morph: CAS). LOUISIANA: Bos- sier Parish, 10 mi. S of Plain Dealing, fire lane in young pine-hardwood stand, sandy loam, Shinners 24488 (com- pletely clips orph: NO; densely strigillose morph: SMU). TEXas: Waller Co., ditches, Hempstead, Hall 221 (completely aa morph: GH, MO; densely strigillose orph: NY; mixed collection: F, NY — 2 sheets, US). In these cases floral and vegetative characters and even the seed surface pattern are exactly the same in the completely glabrous and the densely strigillose individuals. Plants of these two morphs y well differ only by a single allele that controls ub. expression of pubescence in plants. It is also worth noting that plants of the completely glabrous morph are only found scattered in Arkansas, Lou- isiana, and Texas, the main distribution range of the densely strigillose populations. Plants of the completely glabrous morph were previously in- d by Munz (1944, 1965) as a part of the population of the subglabrous morph (as Ludwigia linearis var. linearis), which is certainly not ap- propriate, as discussed above. imilarly, completely glabrous individuals that are we single-allele mutants in populations consisting mainly of densely pubescent plants but are otherwise similar morphologically occur in Lud- wigia hirtella Raf. (sect. Ludwigia; Peng, un- published). 4. Intermediate morph. Any plant that is more pubescent than those of the subglabrous morph and less pubescent than the densely strigillose morph is considered “intermediate” here. The pubescence ranges from scattered minutely strigillose on abax- ial midvein and/or submarginal veins to sparingly strigillose on both surfaces of the leaves. The cap- sule wall is minutely strigillose and not scaly strig- illose. Floral characters generally fall in the in- termediate range of the subglabrous and the densely strigillose morphs. The seed surface cells, mostly elongate transversely to the seed length, are similar to those of the densely strigillose morph. In some ses, however, the seed surface does not have sell. defined cells and is difficult to study. At other times, it is clearly intermediate between that of the subglabrous and the densely strigillose morphs. Plants of the intermediate morph are widely scattered throughout the range of both the subgla- brous morph and the densely strigillose /complete- ly glabrous morphs. They are found in two counties in coastal North Carolina, very well represented in the Coastal Plain of South Carolina, scattered in a few counties in Georgia, Florida, and Alabama, and abundant in Mississippi, where the subglabrous and densely strigillose morphs meet. West of the Mis- sissippi River, they are also found as scattered populations in Arkansas, Louisiana, and Texas, the main distribution range of the densely strigillose morph. Plants designated as intermediate morph" here represent an artificial assemblage of plants of Lud- wigia linearis that may have originated from var- ious combinations of somewhat differentiated pop- ulations. For example, the intermediate plants east of the Mississippi River often co-occur with subgla- brous plants and may represent hybrids and their derivatives between plants of the subglabrous and of the densely strigillose morphs. On the other hand, intermediate plants that grow west of the Mississippi River may represent hybrids and their derivatives between the completely glabrous morph and the densely strigillose morph, as suggested by the following mixed collections: .S.A. ARKANSAS: Prairie Co., along 70, E of Carlisle, Buker in 1956 (mixed collection of one glabrous plant 252 Annals of the Missouri Botanical Garden TABLE 4.

LOUISIANA: Winn Parish, NW pletely glabrous morph: USF; intermediate morph: NCU). Plants of the subglabrous populations are some- what distinguishable from the densely strigillose plants (Table 4) and are separable geographically (the boundary is roughly along the Mississippi Riv- er). Engelmann & Gray (1845) formally recognized the distinctiveness of the two morphs. However, with the abundant intergradation between the two races of L. linearis, as already noted by Engelmann & Gray (1845), “*... these characters (of L. lin- earis var. puberula) pd shading away into the ordinary L. linear a as the occurrence of the ddr i ious populations that have further complicated the character com- binations of L. linearis, I think a discussion of the variation pattern within this species is more useful than recognizing infraspecific taxa. Ludwigia linearis was reported as naturalized in marshy areas of Japan (Asai, 1970), and this report was taken up by Osada (1976) in his illus- trations of the naturalized plants of Japan. How- ever, an examination of Asai’s voucher specimen at TI (Japan: Honshu, Mie Pref., Suzuka-shi, Asa- higaoka-machi (Shirako-machi), October 9, 1966, H. Ohta s.n.) revealed that it actually represents L. perennis L. (sect. Caryophylloidea), which is widely distributed in the tropics and subtropics of the Old World and ranges north to Taiwan and southeastern China (Raven, 1963). wigia linearis can readily be recognized by its sublinear leaves, four yellow petals, and elon- gate-obpyramidal capsules with a shallow, central, longitudinal groove on each side. The only other species in sect. Microcarpium with which L. lin- earis might be confused is L. linifolia, which also occurs in the Coastal Plain and the Florida pen- insula, but much less commonly. These two species are similar in having very narrow leaves, petalifer- ous flowers, and elongate capsules. My biosyste- matic study (Peng, 1988) has shown that they differ by at least a reciprocal translocation. A com- parison of morphological characteristics in these two related species and L. stricta, which is endemic to Cuba, is petaliferous, and has elongate capsules, is summarized in Table Ludwigia linearis and the unrelated Latin American congener L. latifolia are unique in the genus in having conspicuous, transverse paren- chymatous septa in the anthers, which divide the sporogenous tissue into packets (Eyde, 1977; Tobe & Raven, 1986). Before the dehiscence of the anther, however, all of these packets fuse and form one continuous area of sporogenous tissue as a result of disintegration of the septa, leaving the conspicuous vestiges of the distintegrated septa on the inner surface of the anther wall (Tobe & Raven, 1986). Ludwigia linearis is facultatively outcrossing, having four stamens held away from the stigma at early anthesis and arched over, tightly appressed against the unique, elongate stigma a few hours after anthesis. Ludwigia linearis is usually very floriferous and has the highest seed set per capsule in sect. Mi- crocarpium, about 600 seeds per mature capsule. Ludwigia linearis co-occurs with L. glandu- losa, L. lanceolata, L. linifolia, L. microcarpa, L. pilosa, L. sphaerocarpa, and L. suffruticosa in the field. Confirmed natural hybrids include L. linearis X L. glandulosa (two collections) and L. linearis X L. sphaerocarpa (one collection). In both cases, hybrids are triploid, fertility as to seed and pollen is nearly zero. Ovaries turn yellowish Volume 76, Number 1 1989 Peng 253 Ludwigia sect.

KEY TO THE SUBSPECIES OF LUDWIGIA GLANDULOSA Capsules (4-)5-8(-9) mm long; seed surface cells elongate parallel to seed length a sp. glandulosa Capsules 2-4 mm long; seed surface calls elongate transversely to seed length ... b. subsp. brachycarpa The two entities here regarded as subspecies of Ludwigia glandulosa were first recognized as dis- tinct by Torrey & Gray (1838-1840). Ludwigia glandulosa subsp. brachycarpa differs from subsp. glandulosa in its smaller stature, narrower leaves, and smaller flowers and capsules. Furthermore, the seed surface pattern of these two entities—a fea- ture that is often diagnostic in Ludwigia sect. Microcarpium —is sharply distinct, as given in the ey. Ludwigia glandulosa subsp. glandulosa is very common and widespread throughout the Atlantic and Gulf coastal plains and the Mississippi Em- bayment, westward to eastern Texas and south- eastern Oklahoma. Subspecies brachycarpa ranges just on the western edge of that of the subsp. glandulosa in northern Texas and Oklahoma. It grows in the same area as subsp. glandulosa throughout much of its range but extends farther south and west. The general distinctiveness of these two subspecies, without doubt, is maintained by their modal autogamy; vegetative reproduction by means of stolons may likewise play a role in pre- serving favored genotypes. 4a.

Plants of L. glandulosa subsp. glandulosa are commonly found in roadside ditch- es, marshes, pond borders, wet meadows, swales, alluvial floodplains, peaty bogs, moist pinelands, swampy woodlands, and occasionally on waste ground. Ludwigia glandulosa subsp. glandulosa occurs throughout the Coastal Plain from extreme southeastern Virginia southward through eastern North Carolina, South Carolina, south and central Georgia to the panhandle of Florida and westward across southern Alabama, Mississippi, and Louisi- ana, reaching its western limit in eastern Texas. To the north, this subspecies extends through ex- treme southeastern Oklahoma, south and central Arkansas, and up the lower Mississippi basin to southeastern Missouri, central and eastern Ten- nessee, extreme western Kentucky, southernmost Illinois, and southwestern Indiana. Disjunct pop- ulations of L. glandulosa subsp. glandulosa are found in northcentral Missouri (Fig. 43). Flowering from June to September; fruiting from June to October. po specimens examined. U.S.A.

The other three species with elongate capsules are the diploid, petaliferous, nar- row-leaved L. linearis, L. linifolia, and L. stricta. Raven & Tai (1979) suggested that L. linearis is similar to L. glandulosa and might be directly related to it. The biosystematic study of Peng (1988), however, demonstrated that the genetic relationship between the diploid L. linearis and the tetraploid L. glandulosa is not any closer than that between L. linearis and other tetraploids. Fur- thermore, it has been shown that no extant diploids are involved directly in the formation of any tet- raploid species in sect. Microcarpium. Ludwigia glandulosa subsp. glandulosa is known to occur together with subsp. brachycarpa, L. linearis, L. linifolia, L. microcarpa, L. pilosa, |. sphaerocarpa, and L. palustris (sect. Dantia) in the field. It has been known to form natural hybrids with all but L. microcarpa, an extreme selfer, and the facultatively outcrossing £. linifolia. Attempts to synthesize L. glandulosa X L. lini- folia in the experimental greenhouse also failed ~ Peng, 1988), presumably owing to incompatible genomes. Artificial hybrids between L. glandulosa subsp. glandulosa and L. microcarpa, however, were healthy and floriferous. Duke (1955) was the first to record a natural hybrid population of Ludwigia glandulosa subsp. glandulosa x L. pilosa, although he did not fully describe the situation he observed. Tetraploid hy- brids like this and others are usually fertile and are intermediate in such diagnostic characters as ves- titure, sepal and bracteole length, capsule shape and size, seed surface pattern, and whether pollen is shed singly or as tetrads. Triploid natural hybrids involving L. glandulosa subsp. glandulosa and diploids like L. linearis and L. palustris may be floriferous but are highly sterile as to pollen and seeds. Their ovaries turn yellowish or pink and dehisce early. Ludwigia glandulosa subsp. glan- dulosa (stems erect, leaves alternate) X L. palus- tris (stems prostrate, leaves opposite) generally re- sembles L. glandulosa subsp. glandulosa but has slightly broader leaves and smaller flowers. The stems are erect and then prostrate and erect again in some cases; the leaves are alternate like L. Volume 76, Number 1 1989 Peng 259 Ludwigia sect. Microcarpium glandulosa subsp. glandulosa. By contrast, hy- brids of L. glandulosa subsp. glandulosa and L. linearis are similar to L. linearis, having some yellow petals and narrow leaves. The number of petals on each flower varies from 0 to 4. 4b. Ludwigia glandulosa Walter subsp. brachycarpa (Torrey & A. Gray) Peng, Ann. Missouri Bot. Gard. 73: 490. 1986.

Plants of Ludwigia polycarpa grow in ditches; on moist prairie; on alluvial ground of ponds, lakes, and rivers; in marshes; in swales; along edges of lagoons; and in low fallow fields. Contrary to all other species in sect. Microcar- pium, L. polycarpa is centered primarily in the central Midwest, ranging from southcentral Mis- souri, eastern Kansas, eastern and northeastern Nebraska, northward and eastward across Iowa and southern Minnesota into central Wisconsin and the Upper Peninsula of Michigan. In the east, this species occurs in extreme southern Ontario and the eastern part of the Lower Peninsula of Mich- igan. Ludwigia polycarpa extends southward through western and southern Ohio, northcentral Kentucky, and western West Virginia. Scattered populations occur in central Virginia, southcentral Pennsylvania, Massachusetts, and Connecticut. A highly disjunct, presumably introduced population has been recorded from Kootenai County, Idaho (Fig. 45). Flowering from June to September; fruit- ing from July to October.

(NCU) Ludwigia polycarpa is the only species in sect. - Microcarpium that occurs consistently north of 37°N, in the central Midwest of the United States. The report of Kral (1976) on the range extension f L. polycarpa to Covington Co., Alabama (Kral 40992, FLAS, GH, MO, NCU, NY, US, USF, VDB), was based on a pure F, stand of natural hybrids between L. pilosa and L. glandulosa. Ludwigia polycarpa is therefore effectively iso- lated geographically from all other species in the same section except L. sphaerocarpa, which has ide distribution throughout the Atlantic and Gulf coastal plains, also with scattered populations in the northeastern states as well as around the south- ern border of Lake Michigan (Fig. 45). Indeed, natural hybridization takes place where geograph- ical isolation is not maintained, as is evidenced by the presence of fertile hybrid populations of L. polycarpa X L. sphaerocarpa found in Starke Co., Indiana (Peng, 1988). Furthermore, sterile, intersectional hybrids between L. polycarpa and the prostrate, opposite-leaved L. palustris (sect. Dantia), which is very widespread throughout the eastern half of the United States, are found in Ballard Co., Kentucky, the southern border of the range of L. polycarpa (Peng, 1988) Herbarium specimens of Ludwigia polycarpa are rarely misidentified due partly to its geograph- ical isolation and partly to its distinctive morphol- ogy. Plants of L. polycarpa are generally uniform and are characterized by having densely minutely papillose-serrulate leaf margins, elongate-acumin- ate sepals with reflexed tips, long bracteoles (3.5— 6.5(-8) mm) attached above the capsule base, and the oblong-obovoid capsules that frequently exhibit reticulate markings along the rounded corners.

Microcarpium from their lower nodes in late flowering season, like other species do. Their stolons, however, are much shorter, normally up to 15 cm, and their leaves, unlike those of any other species of sect. Microcarpium, are often densely congested and overlap at the apex of the sparsely leaved stolons. The modified stolon is comparable to the peren- nating turion of Epilobium (Keating et al., 1982), which apparently serves as an adaptation to the severe winter that plants of L. polycarpa have to endure in the northern states. The short stolons are occasionally found growing from the nodes of aerial stems that have fallen to the ground. Such specimens include: U.S.A. ILLINOIS: dde 1886, Ohlendorf s.n. Toe ae Smith 676 (F).

Its leaves are rounded to obtuse at the base and clearly sessile. It has a very compact, racemose inflorescence at the very top of each erect stem, as is suggested by the name “Ludwigia capitata," an illegitimate synonym of L. suffru- ticosa Walter, coined by Michaux (1803). The stems are usually single or occasionally with one or two or more branches arising directly beneath the main inflorescence. These branches always rise above the main inflorescence and are each ter- minated by a smaller compact raceme. Further- more, each flower is usually subtended by a re- duced, bractlike leaf in addition to the bracteoles that flank the ovary. It is also the only species in sect. Microcarpium that perennates mainly by un- derground rhizomes. Stolons that float or send roots into mud, prevalent in many other species, are not common in L. suffruticosa. It is especially peculiar in having variously pubescent inflorescences and lower stems, stolons, and underground rhizomes but is otherwise completely glabrous in the mid- dle—see below. The flowers of this species are characteristically very compactly arranged into a raceme up to 5 cm long. The following specimens examined, how- ever, have less compact and longer inflorescences but are otherwise typical of Ludwigia suffruticosa: Caloosa Forest/Expt. U.S.A.

The distribution pattern of pubescence in plants of Ludwigia suffruticosa is peculiar and variable. The plants range from being completely glabrous to densely, minutely hirtellous with multicellular hairs up to 0.6(—0.8) mm long on rhizomes, stolons, stolon leaves, stem base, and basal leaves of the lower plant body and peduncles, pedicels, flower- subtending leaves, and bracteoles of the upper part but are completely glabrous in the middle part of the plant body. The capsules are usually completely glabrous. In the following specimens, however, erect, microscopic protuberances ca. 0.02-0.1 mm long are found evenly but not densely distributed on the fruit wall: U.S.A.

FLORIDA: Duval Co., vicinity of Mayport & Jacksonville, 1870-1876, Keeler s.n. (NY). Ludwigia suffruticosa, L. alata, L. pilosa, and L. sphaerocarpa are the species in sect. Micro- carpium that do not undergo mechanical self-pol- lination. With its whitish creamy sepals, which are very showy in the dense flower aggregates, the cross-pollinating L. suffruticosa successfully at- tracts many insects, mostly bumblebees, honey- bees, and wasps. It occurs with at least four species of Ludwigia (L. alata, L. linearis, L. lanceolata, and L. pilosa) in the field, hybridizing with all but L. linearis. These results are mirrored in the bio- systematic study (Peng, 1988): artificial hybrids between L. linearis and L. suffruticosa are weak and inviable, whereas the other combinations that occur in nature have been synthesized successfully and were very vigorous in the experimental green- house. Remarks on natural hybrids between Ludwigia suffruticosa and either L. alata or L. lanceolata are provided in the accounts of L. alata and L. lanceolata. Natural hybrid populations of L. suf- fruticosa X L. pilosa have previously been given a varietal status within L. suffruticosa (as L. cap- itata Michaux 8 pubens) by Torrey & Gray (1840), which was subsequently and incorrectly considered to be a synonym of L. pilosa by Munz (1944, 1965). The hybrids are densely hirtellous through- out, but the hairs are not as long as those of L. pilosa, and the sepals are neither cuspidate nor elongate-acuminate, but rather acuminate. Fur- ther, their stems are not well branched, their leaves are often long and narrow, their flowers are in more or less congested racemes on the upper part of the stem or branch, and the leaves that subtend their flowers are slightly reduced and bractlike. The combination of these characteristics clearly suggests that such plants represent hybrid popu- lations of L. suffruticosa X L. pilosa. The possi- bility that L. ravenii, the only species other than L. pilosa that is consistently densely hirtellous, was involved in their parentage is reduced because it is rare and not known to occur with L. suffruticosa. Furthermore, the seed surface of the hybrid plants consists of subisodiametric cells, a characteristic of both L. suffruticosa and L. pilosa, but not of L. ravenii. 7. px lanceolata Elliott, Sketch Bot.

However, it is most similar to the hexaploid L. alata in general aspects and fruit morphology, and is suspected to have been one of the parents of that species (Peng, 1988). For a detailed dis- cussion of these two species, see remarks under L. alata and Table 5. Ludwigia lanceolata has been found growing with L. pilosa, L. suffruticosa, both tetraploids, and with the diploid L. linearis. Ludwigia alata and L. lanceolata have not been found growing together, although they have overlapping ranges in the eastern and central Florida panhandle. It is worth noting that, although both species occur in generalized, wet habitats, such as the borders of itches, ponds, and swamps, L. lanceolata, unlike L. alata, is not found in the limestone prairies and brackish marshes that prevail in the Everglades region of southern Florida. No hybrids have been observed, but they would be very difficult to detect without measuring pollen stainability or determin- ing chromosome numbers. Ludwigia lanceolata intergrades with L. pilo- sa, and fertile hybrids between them are frequent in nature. Such hybrids were named L. simulata by Small (1903). The type at NY (West Florida, Biltmore Herbarium) shows a combination of densely strigillose hairs and four-angled or barely winged capsules; it apparently arose following hy- bridization between a parent with strongly winged capsules (L. alata or L. lanceolata) and one that was pubescent (L. pilosa, L. ravenii, or L. sphae- rocarpa). The isodiametric seed surface cells, com- bined with the fact that these plants shed their pollen grains as tight tetrads clearly suggest L. lanceolata and L. pilosa as the parents. Two other collections identified as this hybrid are also from lorida U.S.A. FLORIDA: Franklin Co., Apalachicola, Chapman s.n. (F, US). Highlands Co., Bar Point, Lake Childs, Brass 15532 (GH, US). Ludwigia lanceolata also intergrades with L. suffruticosa. For example, putative parents and introgressed hybrid populations were found in the same sandy ditch by a prairie in Hillsborough Co., Florida (Peng 4324, 4328, MO). The leaves of the hybrids were narrow like those of L. suffruti- cosa, but the stems were well branched above the middle. The flowers are produced in somewhat congested racemes at the top of each branch, and the capsules were obpyramidal and weakly four- angled. Peng 4324 had 85% stainable pollen and formed 16 bivalents in meiosis. 8. Ludwigia alata Elliott, Sketch Bot. S. C. & Ga. 1: 212. 1817. Isnardia alata (Elliott) DC., Prodr. 3: 61. 1828.

The habitats of L. alata include ditches; shores of ponds and lagoons; peaty or sandy swales; open cypress swamps; sandy borrow pits in open pine woods; swampy, flat outcrops of oolitic rocks; wet savannas; tidal flats; brackish marshes; sandy beach strands; and hammocks. This species occurs along the eastern Coastal Plain from southeastern Virginia through eastern North Car- olina, with sporadic populations in eastern South Carolina and Georgia; it reaches its southern limit at localities scattered throughout the Florida pen- insula. To the west this species extends along the Gulf Coast through the Florida panhandle into southern Alabama, Mississippi, and extreme east- ern Louisiana (Fig. 38).

Ludwigia alata has been confused with L. lan- ceolata (Long & Lakela, 1976; Raven & Tai, 1979; Godfrey & Wooten, 1981; Wunderlin, 1982; Clewell, 1985), owing to their similarity in being glabrous, apetalous, and most notably, in having winged, obpyramidal fruits, a character not shared by other species of sect. Microcarpium. Raven & Tai (1979) reported the chromosome numbers of L. alata. They reported tetraploid counts of n — 16 and hexaploid counts of n — 2 as a result of not differentiating L. lanceolata from L. alata. It has now become clear that L. alata is a hexaploid and L. lanceolata is a tetraploid (Peng, 1988). In my biosystematic study (1988), I reported that reciprocal artificial hybrids between the two species exhibit a modal meiotic configu- ration of 16 bivalents and 8 univalents, which suggests that they have two genomes in common. Similar results were obtained when the hexaploid L. alata was crossed with any of the other tetra- ploid species of sect. Microcarpium. Cytogenetic and morphological data suggest that L. alata may have originated following hybridization between the tetraploid L. lanceolata and the diploid L. micro- carpa or populations ancestral to them (Peng, 1988). Despite their superficial resemblance, Ludwigia alata differs sharply from L. lanceolata in that the pollen grains are shed singly in L. alata and as tetrads in L. lanceolata (Praglowski et al., 1983), and the seed surface cells are columnar in £. alata vs. suborbicular in L. lanceolata. Other characters used by monographers to differentiate the two species include seed shape (ovoid in L. alata vs. cylindric in L. lanceolata) and sepal shape and size (slightly longer in length than width and nearly as long as the capsule in L. alata vs. about as long as wide, shorter than the capsule in L. lanceolata) (Small, 1933; Munz, 1944, 1965). These char- acters, however, are not always clear and reliable. The leaf base is usually decurrent in Ludwigia alata, resulting in the winged stem. The wings are up to 1.8 mm wide in extreme cases. In L. lan- ceolata, by contrast, the stems are nearly smooth. However, the character of the winged stem in L. alata is too variable to be diagnostic. Ludwigia alata has, like all other tetraploids of the section, lost its petals in the course of evolution. In a specimen collected from Duval Co., Florida (Creager 639, NCU), one vestigial petal is present on a single flower. Progeny of Peng 4205 collected from Dade Co., Florida, exhibited minute, vestigial petals on some flowers, too, in greenhouse culti- vation. Although normally lacking petals, L. alata has whitish sepals that flare outward. This char- acter, along with the fact that the distance between the androecium and the gynoecium is such that mechanical self-pollination cannot usually occur, indicates that L. alata is an obligate cross-polli- nator. By contrast, L. lanceolata has greenish, ascending sepals and is modally self-pollinating. Ludwigia alata and L. lanceolata are compared in Table 5. Ludwigia alata occurs with L. curtissii, L. linifolia, L. microcarpa, L. pilosa, L. simpsonii, and L. suffruticosa. Natural hybrids between L. alata and L. pilosa, and between L. alata and L. suffruticosa, all of which require insect vectors to effect pollination, are abundant. (See Peng [1988] for voucher information of such natural hybrids.) The hybridity of field populations of L. alata x L. pilosa is initially suggested by the combination of the winged ovaries/capsules and minute, uni- form pubescence found in these plants. Of the 15 taxa in sect. Microcarpium, only L. alata and L. lanceolata have winged capsules, and they are glabrous. Ludwigia pilosa and L. ravenii are con- sistently pubescent, and L. sphaerocarpa is vari- able in vestiture; none of them has winged capsules. The parentage of the hybrids between L. alata (n — 24) and L. pilosa (n — 16) is further verified by (1) their reduced level of stainable pollen (ca. 45-70%, which is indicative of a heteroploid cross), and (2) a mixture of columnar and isodiametric cells and some other irregular cells on their seed surface (among the pubescent putative parental species, only L. pilosa differs significantly in the seed surface pattern from L. alata). Natural hybrids between Ludwigia suffruticosa (n = 16) and L. alata (n = 24) are difficult to recognize in the field. They are very similar to L. alata in general aspect, having winged capsules and slightly winged stems, as well as pollen grains are borne only in the upper leaf axils of each Volume 76, Number 1 1989 Peng 277 Ludwigia sect. Microcarpium branch; their capsules are smaller, presumably as a result of reduced seed set; and their seed surface consists of a mixture of many columnar but rela- tively shorter metric cells (typical of L. suffruticosa), and is ir- regular cells, as well as somewhat isodia- 9.

Plants of L. sphaerocarpa grow in drainage ditches, on stream or pond shores, and in river marshes, swales, swamp forests, edges of limestone sinks, peaty bogs in pastures, and inter- dunal marshes. This species has an extensive dis- tribution along the Atlantic coast, ranging from Massachusetts to northcentral Florida. To the west it extends through the panhandle of Florida, south- western Georgia, southeastern Alabama, central and southwestern Louisiana, and reaches eastern Texas. Disjunct populations occur in southcentral Tennessee, extreme southwestern Indiana, along Lake Michigan in northeastern Illinois and north- western Indiana, and in westcentral New York (Fig. 52).

Its variability is largely the result of its wide geo action of differential adaptation and genetic drift made possible by its pattern of distribution, and its possible hybrid nature (see below). Hybridization with L. pilosa in regions where their ranges overlap apparently provides an important source of vari- ability in L. sphaerocarpa. Populations of this species consist of individuals that vary in overall pubescence, leaf shape and size, fruit size, and density of fruits on branches. Fernald & Griscom (1935) recognized var. jun- gens, var. macrocarpa, and var. deamii based on various combinations of these characters. In their treatment, the varieties were separated as follows: Rameal leaves strongly reduced, glabrous or pubes- cent, lanceolate. Mature hypanthium small, 2.5-3.2 mm long, m broad, averaging broader than long. Hypanthium pubescent; leaves narrowly line- ar-lanceolate and attenu ate Lees COMIS var. "typica" [var. TM Hypanthium, branches, and leaves pubescent; eaves more broadly lanceolate, not a Haire penu rum larger, 3.5-4.6 mm pe ng, 3.2-4 mm broad, averaging longer than broad var. macrocarpa Rameal leaves scarcely smaller than the primary nes, pubescent, narrowly oblong; stems pubes- cent; hypanthium eE 3 mm long, about as wide var. deamii In his revisions of the New World species of pad Munz (1944, 1965) reduced var. deamii o synonymy under var. jungens and presented ds following key to the varieties: Fruit crowded on branches, 3.5-4.5 mm long, not as wide. Massachusetts to New Jersey ..... var. macrocarpa Fruit not ue on branches, 2-3.2 mm lon usually Main stems id leaves usually glabrous; principal leaves linear-lanceo ate and over 7 cm lon Rhode Island to Florida .......... var. sphaerocarpa Main stems and leaves ae io to strigose, lan- ceolate, usually less than 7 cm long. New Jersey to North Carolina, Michigan, and Indiana ..... var. jungens A study of numerous herbarium specimens not available to Fernald & Griscom (1935) and Munz (1944, 1965) has revealed that correlations be- tween these characters are not consistent; the often intergrade. Indeed Munz (1944) noted that r. typica (the typical variety) and var. jungens Maot freely.” Under Ludwigia sphaerocar- pa var. macrocarpa, he also wrote, “New Jersey material is sometimes difficult to distinguish from var. typica (the typical variety)." In my opinion, it is best to treat L. sphaerocarpa as representing an assemblage of variable populations without rec- ognizing the infraspecific taxa. These populations share the following diagnostic characters: subglo- bose capsules, diminutive bracteoles (shorter than 1.5 mm long), and ovate-deltoid, yellowish, con- spicuous sepals. Volume 76, Number 1 1989 Peng 281 Ludwigia sect. Microcarpium It is also of interest to note that, although the seed surface cell pattern is generally very regular within populations of members of Ludwigia sect. Microcarpium (Figs. 19-28, 30-34), this is not the case for L. sphaerocarpa (Fig. 29). The seed surface is arranged in columnar cells both trans- versely elongate and parallel to the seed length, the former alignment often predominating in the central part of the seeds. Seeds with variously oriented surface cells are also seen in some pop- ulations. Comparison of the seed surface pattern in populations of L. sphaerocarpa with that of various artificial hybrids strongly suggests that ear- lier hybridizations within the interfertile tetraploid group of sect. Microcarpium may have resulted in this widespread series of populations that are more or less stabilized in some of their character- istics, and such hybridizations may still be contrib- uting to the variability of this series of populations. The biosystematic study of Ludwigia sect. Mi- crocarpium (Peng, 1988) demonstrated that hy- brids between species that differ in their seed sur- face cell pattern always show a mixture of cell types or cells of intermediate shapes and sometimes of randomly oriented cells. Similarly, hybrids re- sulting from crossing a densely hirtellous species with a glabrous one always exhibit minutely villous or strigillose pubescence. Of the tetraploid Lud- wigia taxa that are interfertile with L. sphaero- carpa, L. ravenii and L. glandulosa subsp. "pehyearpe are the only ones with columnar seed lls elongate transversely to the seed length, = mw L. polycarpa and L. glandulosa subsp. glandulosa are the only taxa with columnar seed surface cells elongate parallel to the seed length. Both subspecies of L. glandulosa, having narrow, subcylindrical capsules, are unlikely to be parents of L. sphaerocarpa. In seed surface pattern and overall pubescence, L. ravenii (densely hirtellous) and L. polycarpa (glabrous) seem to be suitable parental candidates. However, that they both have oblong-obovoid capsules and are highly autoga- mous, in contrast to subglobose capsules and out- crossing habit of L. sphaerocarpa, renders it un- likely that they have been involved directly in the formation of L. sphaerocarpa. One or possibly both parents of L. sphaerocarpa are likely extinct. The morphological variation in Ludwigia sphaerocarpa is further complicated by its fre- quent natural hybridization with L. pilosa, which has apparently resulted in many hybrid swarms or introgressed populations. These plants generally exhibit varying degrees of intermediacy in diag- nostic characters such as seed surface pattern, overall pubescence, bracteole size, sepal shape and size, and leaf shape. The following specimens show intermediacy in at least two of the above characters or a combination of some of the diagnostic features of L. pilosa with some of those of L. sphaero- carpa: U.S.A.

Some of the above putative hybrid populations are from central and southern Florida, where nei- ther typical Ludwigia pilosa nor L. sphaerocarpa occur (Peng, 1988, fig. 22). This suggests that their physiological characteristics, and thus their ecological tolerances, may differ from those of the parents in such a way as to allow them to occur in novel habitats and areas where neither of their parents can survive The following collections are unusual in being densely hirtellous (having erect hairs ca. 0.4-0.8 282 Annals of the Missouri Botanical Garden mm long), but they are otherwise typical of Lud- wigia sphaerocarpa. They may represent intro- gressants between L. sphaerocarpa and either pilosa or L. ravenii. U.S.A. FLORIDA: Flagler Co., vicinity of Andalusia, Godfrey & Reinert 61149a (FSU).

Judged by their morphology as well as their full seed set, these plants are more likely to be mutants showing an ancestral trait rather than hybrids be- tween Ludwigia sphaerocarpa and one of the petaliferous species of sect. Microcarpium. Almost all populations of Ludwigia sphaero- carpa. are at least sparingly strigillose, especially on the ovary /capsule walls. The following two gla- brous collections from Louisiana are exceptional: .S.A. LOUISIANA: Cameron Parish, in “The Pool," Lacassine Wildlife Refuge, Thieret 16410 (DUKE, GA, MO, SMU). Rapides Parish, Red River, 1840, Hale s.n. (US). They seem to parallel the glabrous variants of Ludwigia linearis (see above) in which a few gla- brous plants may grow intermixed locally with densely strigillose individuals. Ludwigia sphaerocarpa is one of the few species in sect. Microcarpium in which the distance be- tween the androecium and the gynoecium is such that self-pollination is impossible without the inter- vention of pollen vectors. Although the flowers of L. sphaerocarpa are apetalous, their sepals are adaxially yellowish. This, along with the bright yel- low nectary disc, which produces copious nectar, attracts many insects to the flowers of this appar- ently largely outcrossing species. n the field, Ludwigia sphaerocarpa grows with L. glandulosa, L. linearis, L. microcarpa, L. pi- losa, and L. polycarpa and hybridizes with all but the small-flowered, modally selfing L. microcarpa. The natural hybrids generally exhibit intermediate morphology, most notably in fruit shape and size, bracteole length, overall pubescence, and seed sur- face cell pattern. The fruits are plump and contain abundant seeds in homoploid (tetraploid) hybrids. In the heteroploid (triploid) L. sphaerocarpa (n = 16) x L. linearis (n — 8), one to four petals were present in most flowers, and seed set was negligible. In the experimental greenhouse, artificial hy- brids have been synthesized between Ludwigia sphaerocarpa and the diploid L. linearis, L. mi- crocarpa, the tetraploid L. glandulosa, L. poly- carpa, L. suffruticosa, L. lanceolata, L. pilosa, the hexaploid L. alata, and the octoploid L. cur- tissii (Peng, 1988). 10.

Ludwigia pilosa is a distinctive species in sect. Microcarpium characterized by being densely hir- tellous throughout; reddish brown leaf midveins especially abaxially; sepals elongate-triangular, creamy, and often tinged with pink, reflexed at the tips; and capsules subglobose to somewhat oblong- obovoid, with a pair of long bracteoles attached slightly above the base. The only species that has consistently been confused with L. pilosa is the recently named L. ravenii (Peng, 1984). The sim- ilarity in these two species is in aspect and in the vestiture. They differ in many other characters, notably floral parts and breeding systems. Lud- wigia ravenii is modally autogamous, with obscure greenish sepals, and all of its floral parts are sig- nificantly smaller than those of L. pilosa. Further, the seed surface cells are transversely elongate rather than subisodiametric. The flowers of Ludwigia pilosa, in contrast, are unable to undergo mechanical self-pollination. Their showy sepals and copious nectar, which is produced by the nectary disc, unfailingly attract various insect visitors such as ants, wasps, bum- blebees, honeybees, and moths to effect pollination. Ludwigia pilosa grows with diploid L. linifolia, L. microcarpa, tetraploid L. glandulosa, L. lan- ceolata, L. ravenii, L. sphaerocarpa, L. suffru- ticosa, and the hexaploid L. alata, which is closely allied to the tetraploid species group. It forms fertile hybrids with probably all tetraploid species and with L. alata when they grow together. Natural hybrids between L. pilosa and L. ravenii are presumably rare (L. ravenii is rare itself) and difficult to detect. An intersectional hybrid between L. pilosa and L. arcuata (n = 16; sect. Dantia) was found in Mobile Co., Alabama (Peng, 1988). All natural hybrids are intermediate morphologically, having vestiture similar to that of L. pilosa but shorter and other Volume 76, Number 1 1989 Peng 287 Ludwigia sect. Microcarpium features diagnostic of the other putative parents (e.g., the winged fruits of L. lanceolata, elongate capsules of L. glandulosa, and additional features). Two such hybrids have previously been named: L. capitata B pubens Torrey & A. Gray (= L. pilosa x L. suffruticosa) and L. simulata Small (= L PE X L. lanceolata). Kral (1976) reported a tension of L. polycarpa to Alabama, based, in fact; on a natural hybrid population of L. pilosa x L. glandulosa. The only species that hybridizes extensively with L. pilosa and produces many hy- brid swarms or introgressed populations is L. sphae- rocarpa. Plants of these populations exhibit a vary- ing degree of intermediacy between the two species. They are discussed further under L. sphaerocar- pa. Hybrids between Ludwigia pilosa and the other tetraploid species or the hexaploid L. alata are readily synthesized in the experimental greenhouse and are quite fertile. It is generally difficult to obtain hybrids between L. pilosa and diploid species or the L. curtissii complex. Floriferous and vigorous hybrids of L. pilosa X L. linifolia and L. pilosa X L. curtissii, however, were obtained. Seed set was nonexistent or negligible in these hybrids. 11.

Self-compatible and modally autoga- mous. Gametic chromosome number, n = 16. Distribution. Ludwigia ravenii occurs in wet, peaty habitats, such as ditches or margins of ponds, bogs, and swamps. It is found as scattered popu- lations in coastal southeastern Virginia, eastern North Carolina, and southeastern South Carolina and with somewhat disjunct populations in north- eastern Florida (Fig. 56). Flowering from July to September; fruiting from August to October. Specimens examined are cited in full in Peng (1984). This recently discovered species consists of scat- tered, morphologically very uniform populations. Owing to its densely hirtellous vestiture and relative rareness, it was previously not well understood and was confused with Ludwigia pilosa, the only other species of sect. Microcarpium that is consistently densely hirtellous; that species, however, is wide- spread and common. As was shown in the table comparing L. ravenii with related species (Peng, 1984), L. ravenii is very distinct from L. pilosa. Ludwigia ravenii has small inconspicuous flow- ers with greenish sepals and short stamens and styles. Its anthers are firmly appressed to the stig- ma shortly after anthesis. These characteristics strongly suggest that it is modally autogamous. This was corroborated by my field study at the type 288 Annals of the Missouri Botanical Garden M NI LÁ (3 Pd — (ye MN Y n CEY. FEAS, SS Sy | ge r E FIGURE 55. Ludwigia ravenii (North Carolina, Sampson Co., Boufford & Wood 18898, CM).—a. Habit. — b. lower.— c. Fruit. —d. Seed.

Ludwigia ravenii does not appear to grow ag- gressively. It starts to form stolons only late in its fruiting season (September to October). Unlike most other tetraploid members of sect. Microcarpium, these stolons are usually slender and short, resem- bling those of L. microcarpa. Consequently, the populations consist of scattered individuals instead of large colonies connected by stolons, as is typical in L. pilosa and other species. Live plants of Ludwigia ravenii were not col- lected until after the completion of my biosyste- matic study of Ludwigia sect. Microcarpium, so its genetic relationships with the other tetraploid Volume 76, Number 1 1989 Peng 289 Ludwigia sect. Microcarpium FIGURE 56. Distribution of Ludwigia ravenii. members of the section remain obscure. The ex- tensive crossing data already available for other species clearly demonstrate, however, that pollen stainability and seed set are high in hybrids between any two tetraploid species, no matter how different morphologically they are (Peng, 1988). Circum- stantial evidence thus suggests that L. ravenii is almost certainly interfertile with other species of the tetraploid group of sect. Microcarpium. 12. Ludwigia microcarpa Michaux, Fl.

Plants of Ludwigia microcarpa grow in roadside ditches, ponds and streams at the borders, low meadows, low areas in open woods, edges of swamp forests, brackish marshes, marshes, hammocks, and solution pits of limestone on marl prairies. This species occurs along the Atlantic coast of North and South Carolina and Georgia, and throughout the Florida peninsula. It extends westward across the panhandle of Florida, southern Alabama, reaching southern Mississippi, with a single population in southwestern Louisiana. To the north, L. microcarpa occurs through west- ern Georgia and central and western Alabama to southcentral Tennessee. Scattered populations are found in northcentral North Carolina and south- central Missouri (Fig. 58). Furthermore, L. mi- crocarpa occurs on several Caribbean islands, in- cluding the Bahamas, Cuba, and Jamaica. Flowering and fruiting throughout the year. Representative specimens examined.

Ludwigia microcarpa is the only diploid species of sect. Microcarpium that is apetalous and has more or less spatulate leaves. It has the smallest stature, leaves, flowers, and fruits and has the fewest seeds (ca. 10—20) per capsule of any species in the section. Occasionally it may be confused with plants of the “L. curtissi complex” (including a hexaploid, L. simpsonii, and an sopla, E curtissii), which have similarly spatulate leaves a turbinate fruits. It is, however, Lon maet A the “L. curtissii complex" by its minute capsules (1-1.5 mm long), which are shorter than or sub- equal to the sepal, its nectary disc of four flat greenish spots, and its reddish seeds. For detailed comparison, see Table 6 Ludwigia microcarpa is uniform in reproduc- tive structures but variable in vegetative habit. The stems are, as a rule, erect and usually well branched but are sometimes single. The stems and branches are straight or slightly zigzag. In outline, the plants subequal, ascending branches throughout the nodes; or they are triangular or ovate when the branches are gradually shorter from lower nodes up. The stems are normally annual and herbaceous; the plants may perennate either by forming stolons or by sending new shoots up directly from the spent stem base of the previous year. Woodiness is seen in some Florida specimens, presumably as a result of a favorable climate. The following specimen from Leon County, Florida, has an exceptionally woody base about 8 mm thick: sandy alluvium bordering wet woodland, Ochlockonee River, W of Tallahas- see, Godfrey 73131 (MO). Most plants of Ludwigia microcarpa start to flower when young; it is common to find plants 5- 10 cm high with flowers/fruits. The apetalous flow- ers are very small, with a tiny, greenish nectary disc from which a small amount of nectar is pro- duced. Mechanical self-pollination apparently pre- dominates in this species. In the experimental greenhouse, however, it crossed to the diploid L. linifolia and L. linearis, tetraploid L. glandulosa, L. lanceolata, L. poly- carpa, L. sphaerocarpa, and hexaploid L. alata and L. simpsonii; these combinations have resulted been successfully in the production of vigorous, floriferous hybrids (Peng, 1988). None set any seed. The F, hybrids between L. microcarpa and other petaliferous dip- 294 Annals of the Missouri Botanical Garden TABLE 6. Comparison of Ludwigia microcarpa with related species.

In other aspects, these F, hybrids were intermediate between their parents. Hybrids between L. micro arpa and species of higher ploidy level generally resembled the latter but tended to have smaller leaves and flowers. Ludwigia microcarpa grows with L. alata, L. curtissii, L. glandulosa, L. linearis, L. linifolia, . pilosa, L. simpsonii, and L. sphaerocarpa. Natural hybrids have been found between L. mi- crocarpa (n — 8) and both L. simpsonii (n — 24) and L. curtissii (n = 32), both of which resemble L. microcarpa morphologically and share a com- mon genome with that species (Peng, 1988). Since L. simpsonii and L. curtissii differ only in quan- titative characteristics, which often overlap, it is impossible to distinguish between L. microcarpa X L. curtissii and L. dae di X L. simpsonii without knowing the chromosome number, or with- out seeing the populations in m field. These hy- brids are usually readily recognizable by their erect stems; small and oblanceolate to spatulate leaves; apetalous flowers; elevated nectary discs; and mi- nute, obpyramidal ovaries that abort after anthesis. he corners of the ovary/capsule often appear winged to some extent, apparently as a result of the aborted ovaries, which fail to develop into seeds in the locules of such hybrid individuals. Hybrid populations between Ludwigia micro- carpa and L. simpsonii are apparently common in Florida, where the two species grow in the same Volume 76, Number 1 1989 Peng 295 Ludwigia sect. Microcarpium habitats, often intermixed. These plants have a modal meiotic configuration of 8 bivalents and 16 univalents (Peng, 1 Confirmed hybrid populations of Ludwigia mi- crocarpa X L. curtissii were found in Martin Co., Florida, 4.3 mi. E of Okeechobee and Martin coun- ty line, on FL 710, at Brady Ranch (Peng 4202, MO). Here they occurred along with putative par- ents by a wide depression between the highway and a railroad. Plants of L. microcarpa grew along the swamp border, whereas plants of L. curtissii stood in deeper water but were not as abundant as the former. Hybrid plants were scattered between them. The hybrids formed 8 bivalents and 24 uni- valents at meiosis (Peng, 1988). Intersectional hybrid populations of Ludwigia microcarpa with L. palustris (sect. Dantia) were found in several counties of North Carolina, Geor- gia, and Florida (Peng, 1988). Their leaves were bopposite or opposite; their fl apetalous, with minute ovaries, and aborting after anthesis; and the stems were prostrate and rooting at the nodes to ascending, suberect, or both. The combination of alternate leaves with a more or less prostrate habit in North American Ludwigia is usually indicative of hybridization between plants of sect. Microcarpium and sect. Dantia. 13.

Adaxial and abaxial views of 298 Annals of the Missouri Botanical Garden polyploid complex, with the diploid L. microcarpa evidently having played a role in the formation of the other species (Peng, 1988). Its distinctiveness from the diploid L. microcarpa is readily perceived in capsule size, shape of nectary disc, seed color, and seed number per capsule. The characters sep- arating L. simpsonii and L. curtissii, however, are nearly always quantitative and often overlap. Raven & Tai (1979) indicated that the diagnostic characters separating L. curtissii and L. simpson- ii, such as capsule shape and size and leaf shape, are not correlated with chromosome numbers, and that the two species tend to converge in the ex- perimental greenhouse. For reasons of this sort, these two species have frequently been merged under L. curtissii in the recent literature (e.g., Long & Lakela, 1976; Raven & Tai, 1979; God- frey & Wooten, 1981; Wunderlin, 1982). By con- trast, basing conclusions on abundant fieldwork and greenhouse and chromosome studies, I (1988) ob- served that the difference in chromosome number is correlated with mature capsule size. All plants with n — 24 have capsules 1.5-2(-2.5) mm long, whereas those with n — 32 have mature capsules (2-)2.5-4(-4.7) mm long. The morphology of plants with n — 24 fits closely the description of L. simpsonii, and the morphology of n — 32 plants clearly corresponds to that of L. curtissii (including L. spathulifolia). Comparison of these two species and the diploid L. microcarpa is in Table 6. Although Ludwigia simpsonii and L. curtissit frequently are found in the same locality, they appear to be ecologically distinct and seldom occur side by side. Ludwigia simpsonii tends to grow along roadsides with other weeds in moist sandy soil. Ludwigia curtissii usually grows farther from roadsides, sometimes mixed with tall grasses or sedges, in black muck and often in deep standing water. Ludwigia simpsonii sometimes grows with L. alata, L. curtissii, and L. microcarpa. Proven natural hybrids are known only of L. simpsonii X L. microcarpa; they occur in several scattered counties in Florida (Peng, 1988). These hybrids showed a modal meiotic configuration of 8 bivalents and 16 univalents and 4-24% stainable pollen. Their ovaries aborted after anthesis. Ludwigia simpsonii may form natural hybrids with L. cur- tissii, but such hybrids would be virtually impos- sible to pick out without studying their chromo- somes and would probably be identified as one of their putative parents. Artificial hybrids between these two closely related species have been syn- thesized; they produced moderate numbers of seeds and had ca. 80-90% stainable pollen. They con- sistently showed a meiotic configuration of 24 bi- valents and 8 univalents, which indicated that chro- mosomes of the three genomes in L. simpsonii pair with homologues in L. curtissii, leaving the eight additional chromosomes in this species unpaired. Based on morphological features and crossing re- lationships, the octoploid L. curtissii was probably derived following hybridization between a petalif- erous, narrow-leaved diploid similar to L. linearis or L. linifolia and the hexaploid L. simpsonii (Peng, 1988). Intersectional hybrids of Ludwigia simpsonii and L. repens (n — 24; sect. Dantia) have been found growing intermixed with both putative par- ents. These plants exhibited few, if any (0-1), associations of chromosomes at meiosis (Peng, 1988), which corroborated an earlier report by Schmidt (1967). The lack of chromosome pairing in hybrids strongly suggests that the three genomes of L. simpsonii are distinct from one another and are not homologous with any of the genomes pres- ent in L. repens. Judged by the fact that L. simp- sonii often has opposite or subopposite leaves near the base of the stem or at the seedling stage, with a somewhat ascending, decumbent, or occasionally prostrate habit, it seems likely that it originated from hybridization between the diploid L. micro- carpa, to which it is similar morphologically and with which it shares one genome, and a possibly extinct member of sect. Dantia with prostrate stems and opposite leaves. Plants from the following collections are excep- tionally fully prostrate and root at the nodes: U.S.A. FLORIDA: Collier Co., 13 mi. N of U.S. 41, on U.S. 29, in vast grassy field behind roadside ditches (Big Cypress Swamp), Peng 4268 (MO), 4273 (in part, MO). They grow side by side with erect plants but are otherwise normal, small-fruited L. simpsonii, ex- hibiting 24 pairs of chromosomes in meiosis and setting abundant fruits with viable seeds. Artificial hybrids between Ludwigia simpsonii and the diploids L. linearis, L. linifolia, L. mi- crocarpa, the tetraploids L. glandulosa, L. lan- ceolata, the hexaploid L. alata, and the closely related octoploid L. curtissii have been synthe- sized, although with difficulty in some cases. Except or L. simpsonii X L. curtissii, which is highly fertile, all other combinations had 3-20% stainable pollen and produced very few, if any, seeds. 14. Ludwigia curtissii Chapman, Fl. South.

These two species are unique in sect. Mi- crocarpium in having loculicidal capsules and in having, along with the diploid L. microcarpa, more or less spatulate cauline leaves. Their capsules de- hisce by four longitudinally lenticular slits opposite the loculi. When dehiscence is complete, the cap- sule is split into four basally united parts topped with persistent but slightly shriveled sepals. This type of capsule dehiscence is highly specialized and has an anatomical basis (Peng & Tobe, 1987). Ludwigia curtissii and L. simpsonii are also dis- tinct in that they are the only species in sect. Microcarpium that rarely produce true stolons. From the perennial base of the previous-year stem they form new shoots that ascend at first and soon become erect. Volume 76, Number 1 1989 Peng Ludwigia sect. Microcarpium Some populations of Ludwigia curtissii from the Everglades of southern Florida and the Ba- hamas tend to have larger capsules (3.5-4.7 mm long) and were named L. spathulifolia by Small (1933). As their variation pattern closely parallels that of L. curtissii s. str., and they are octoploids with n — 32, they are here considered as variants of the slightly rdg fruited L. curtissii that do not warrant taxonomic recognit lon, as was sug- gested by Long & Lakela (1976), Raven & Tai (1979), Godfrey & Wooten (1981), and Wunder- lin (1982). Ludwigia curtissii co-occurs with L. alata, L. linifolia, L. microcarpa, and L. simpsonii and hybridizes with the diploid L. linifolia and L. mi- crocarpa, forming F,s that form flowers but not seeds. Ludwigia curtissii X L. microcarpa ex- hibited 8 bivalents and 24 univalents at meiosis. The pollen stainability was 1676 (Peng, 1988). As discussed above, natural hybrids between L. cur- tissii and L. simpsonii probably occur but would be difficult to recognize. Like L. simpsonii, L. curtissii forms intersectional hybrids with L. re- pens (n — 24, sect. Dantia) in the field. Such plants are vigorous and somewhat prostrate or sub- erect; they have alternate and opposite or subop- posite leaves, but do not form viable seeds. n the experimental greenhouse, artificial hy- brids have been synthesized between Ludwigia curtissii and the diploid L. linearis and the tet- raploids L. glandulosa, L. lanceolata, L. pilosa, L. polycarpa, L. sphaerocarpa, and L. suffruti- cosa. A few seeds were occasionally produced by some of the octoploid X tetraploid hybrids. Compared with Ludwigia simpsonii (n — 24), L. curtissii (n = 32) is generally taller, more robust, more often erect, tends to have narrower and longer leaves, and nearly always has larger flowers and capsules. Further, the leaves of L. curtissii are nearly always alternate throughout, and the flowers occasionally have one to three vestigial petals. As these two species have three genomes in common (Peng, 1988), it is apparent that L. curtissii originated following hybridization between L. simpsonii and a diploid, petaliferous, erect species with narrow and alternate leaves, larger flowers, and longer capsules. The likely can- didate for such a plant is only to be found in L. linearis, L. linifolia, the Cub or their progenitors. Indeed it is even possible that more than one of the above species hybridized with L. simpsonii in the past to form the present-day L. curtissii. If this is true, the morphological vari- ability observed in L. curtissii is expected LITERATURE CITED ANDERSON, E. 1948. Hybridization of the habitat. Evo- lution 2: 1-9. Asal, Y. 1970.

Ana Maria Planchuelo? and David B. Dunn? ABSTRACT The Lupinus lanatus complex is a group of closely related species that grow in southeastern Brazil and northeastern herbaceous, perenn long or longer, and lar Argentina. They are or three-foliate, stipules 3-7 cm ial or occasionally biennial plants with basal leaves in the juvenile plant simple e flowers 15-20 mm long having the banner glabrous and well reflexed from the wings. Two species, L. magnistipulatus and L. setifolius, are described for the first time. This group of species appears to be closely re- lated and can be recognized by the large stipules 3-7 cm or more long and the presence of some simple or trifoliate leaves at the base of the juvenile plants. Completely developed leaves from adult plants have five or more leaflets. They are all herbaceous perennials or short-lived perennials, or occasionally function as biennials. The flowers are commonly 15-20 mm long and glabrous, with the banner well reflexed from the wings and the sides turned back. The calyx cup tapers into the pedicel without the gibbous enlargement that is commonly present in other lupines. We are suggesting that this group of species forms a second lineage derived from L. para- guariensis, which is thought to be the origin of the group, since it possesses morphological char- acteristics reminiscent of the group, including that the juvenile leaves and the first leaf produced on the lateral branches are simple. Planchuelo & Dunn (1984) described L. paraguariensis as showing a transitional stage between simple- and compound- leaved species. Lupinus lanatus has floccose lanate indument on both sides of the leaflets (see Fig. 1A). Vege- tatively it has been described as forming perennial mats up to four feet in diameter in sand dunes, with new growth developing seasonally from the tips of the stems which survive under the sand. Lupinus magnistipulatus, described in this paper, is similar to L. lanatus in the perennial condition but has less lanate hair coating (see Fig. 1B), and as its name suggests, the former develops a much larger free tip on the stipules. Lupinus setifolius, also described in this paper, appears to be biennial. The large free tip of the stipules and the loss of the lanate indument (see Fig. 1C) suggest the latter as a derivative from L. magnistipulatus. The species L. multiflorus, L. albescens, and L. aureonitens, treated by Planchuelo & Dunn (1984), are relatives of this complex. They have caespitose perennial habit and a narrow free tip of the stipules like L. lanatus but develop a much denser indument that grades from densely short- lanate to densely sericeous, completely hiding the leaf surface.

Some of the specimens cited here were labeled by Burkart as a new species, L. reitzii. Our interpretation of the material is that these specimens are juvenile plants and do not differ otherwise from the others. Therefore we have not recognized L. reitzii. The new species apparently grows only in south- eastern Brazil in the states of Santa Catarina and Paraná at altitudes from 700 to 1,650 m. Flow- ering occurs from late October to late January. ne Aedes ud specimens examined. BRAZIL. un. Guarapuana, Guara, Hatchback & Gui- maraes 20492 (NY, US). SANTA CATARINA: Mun.

CONCLUSIONS The three species, L. paraguariensis, L. al- bescens, and L. aureonitens, not treated in this paper are included in the key to facilitate identi- fication of presumably closely related species. In seedlings of L. albescens grown from an herbarium specimen, the first leaf of the plant was simple and the second three-foliate. This particular charac- teristic should be common to the group of species treated in the key, although it is difficult to find in herbarium specimens. Considering the taxonomic studies of the genus Lupinus for South America (Planchuelo-Ravelo, 1984), this complex and its related species are representatives of the lupines of the “Atlantic Region" and are the only group of perennial plants with large compound leaves growing in the area.

Todzia? ABSTRACT Between 1854 and 1858, Augustus Fendler resided in Colonia Tovar, a German village in the Coastal epa of Venezuela, where he assembled on map and list of Fendler e of the finest collections of plant specimens for his time. Fendler's life in Colon aton, A Engelmann, and Josep man e i A ed. An dii list dei il collection dus extracted rut his notebook is given for the angiosperm types that li collected. In the mid nineteenth century South America was poorly known botanically compared with most other parts of the world. At this time, plants gen- erally were collected by people who traveled through one or several countries, making plant specimens along their way (e.g., Ruiz & Pavón; Humboldt & Bonpland). Few collectors lived in an area long enough to sample a region thoroughly and collect the relatively rare species. Augustus Fendler was a notable exception. He resided four years in Co- lonia Tovar,’ a small German colony 35 miles west of Caracas, Venezuela (Rasmussen, 194 collected over 3,000 ferns and flowering plants. These collections are noteworthy, not only for their excellence, but also because a great number of new species were based on his material. To this day, new species are being described from Fendler's Venezuelan specimens (e.g., Croat & Lambert, Although his Venezuelan collections are ex- tremely important, Augustus Fendler is perhaps best known for his collections of New Mexican plants between 1846 and 1847. Gray (1849) pub- lished an annotated list of Fendler's New Mexican plants, which Shaw (1982) discussed more re- cently. Fendler's other collecting trips to Panama, Venezuela, and Trinidad are not as well known as those he took in the United States. In Panama, Fendler (Fig. 1) collected near the Chagres River for four months in 1849 and 1850. He resided in Trinidad from 1877 until his death in 1883. His most valuable collections were made in Venezuela between January 1854, and September 1858. This paper is an account of Fendler's life in Venezuela constructed from his letters to D. Eaton, G. Engelmann, and A. Gray in the Yale University Library, Missouri Botanical Garden, and Gray Herbarium archives, respectively. This cor- respondence provides insight not only into Fendler, but also into the difficulties of life as a plant col- lector in the s. Fendler corresponded with Engelmann in German and with Eaton and Gray in English. These lucid and detailed letters are a chronicle of plant collecting in South America in the mid nineteenth century and are even more remarkable since German was Fendler's native lan- guage According to various biographical notes (Canby, !

At the age of 12 he was sent to a preparatory school where he mastered the fine penmanship that was as delightful to his correspondents as it is to his present-day historians (Fig. 2). Fascinated with traveling, Fendler sailed from Bremen to Baltimore in 1836 and within two years moved to St. Louis. During a visit to Europe in 1844, Fendler met Professor Ernst Meyer of the University at Koe- nigsberg in Prussia, who encouraged him to collect plants in the western United States and send them to him for sale. On his return to St. Louis, Fendler Photograph of Augustus Fendler probably taken in St. Louis, ca. 1860. brought his specimens for identification to George Engelmann, the botanist who advised Henry Shaw, founder of the Missouri Botanical Garden (Stieber & Lange, 1986). Fendler and Engelmann struck up a friendship that spanned nearly 40 years. En- gelmann later introduced Fendler to Asa Gray, who described Fendler as “a close, accurate observer, a capital collector and specimen-maker" (J. L. Gray, 1893: 341). After a year of plant collecting in New Mexico, a failed attempt to collect plants near the Great Salt Lake, and two sojourns in Arkansas and Lou- isiana, Fendler settled in Memphis, Tennessee in 312 Annals of the Missouri Botanical Garden m ^ 1 AL t P / eres aa Poa GU p Le p COP OAPAMA ¿Hna APP Qd A E ASA 3, Ld, c er y 2 Pm y r Zan Coe u^ uU ergi rone e dM. a 2» ¿ue em rf GA > Agi" Lor Sa p^ gs > 2 e ac 00 66 a d Las IA 4 ae ARO TA ira PP ai ite FA a PP oe MMC 2 MEE olari AC > A Agr eS wag vM >) Las 47 The ame ITEE M e ALPP 2274 E p Wee gZIECE.

In 1853, when the lamp-lighting business in Memphis faltered, he was eager for a change of pace and wanted to resume collecting plants. He wrote to Gray on 11 August 1853 about his collecting plans: “My principal object in going to Caracas is: to go into a business again, by which I can support myself. But I hope I shall have plenty of leisure 5:3 . aa dac ——Ó— = Letter by Augustus Fendler to Asa Gray (Memphis, Tennessee, July 13, 1853). Missouri Botanical to make botanical collections besides. If I collect again I shall aim to make the sets as large and complete as possible. Do you think 15 sets, each containing from 1,000-1,500 species of plants collected about Caracas could meet with a ready sale?" On 15 August 1853, he wrote Engelmann that he wished to move to a town near Caracas because “In a city with a population of 70,000 I believe to be able to find more security than here, Volume 76, Number 1 1989 Todzia Fendler's Venezuelan Plant Collections 313 Boo 77 SB A = Co 272 Aero PA ; Mum 777 B77 P ctp por, ov dq nee 7 SAC, Lami P Au E A Fe Tarro a e A ran P ai tr eri T wee PA a e VATES eee AA “SÍ 72 ha.

Then also, the wish to live again in a mountain valley and to be in the vicinity of a rich mountain flora! without having the difficulties of long and difficult communication as I found in Santa Fe." On the 24th of December 1853, Fendler sailed for Venezuela from New York harbor, panied by his chronically ill brother. They arrived accom- in La Guaira, Venezuela, on 21 January 1854. In his day, it took five hours to reach Caracas from the coast. Upon arriving, he commenced collecting plants in the vicinity. Prompted by the high cost of living in Caracas, he went up to Colonia Tovar after only six weeks. After reaching the settlement, he wrote to Gray on 16 December 1854: “The base of the valley is 5,600 ft. above the sea, and some of the surrounding mountains about 2,000 314 Annals of th Missouri B nd Garden ALAN ed, du eo aa rene .

The valley in which this river flows becomes at last very narrow and the road turns off to the left ascending a high mountain, from the tip of which it leads on in a westerly course along the very summit of the prin- cipal mountain range, through the deep shades of the primitive forest and down the valley of the Colony." While at Colonia Tovar, Fendler also corre- sponded with Joseph Henry of the Smithsonian Institution, who published Fendler's letters and me- teorological observations in the Annual Report of the Board of Regents of the Smithsonian Insti- tution. Fendler was an ardent amateur meteorol- ogist and in Venezuela traveled with a barometer, rain gauge, and thermometer. From his corre- spondence with Gray, Fendler provided a very rich description of Colonia Tovar (Fendler, 1857): “The valley in which Colonia Tovar is situated was, so late as December, 1841, a perfect wilderness, cov- ered with primitive forest. Not even the existence of this valley was known fifteen years ago, neither to the government nor to its owner, although it is only thirty-five miles west of Caracas, the capital of Venezuela, and in a straight line cannot be more than twelve miles from the sea. And when an at- tempt was made to explore this region not even a guide could be found for the small exploring party of fifteen men, headed by Colonel Codazzi, a skillful ns A, 2 UR A officer and compiler of the new map of Venezuela. When this party at last succeeded in crossing this region and reaching the sea-shore, they thought they had achieved a most extraordinary thing, (to cross a distance of twelve miles in six days;) and after they had returned to their homes none of them had a desire to do the feat over again. This was a party of natives. And when, at a later period, after the establishment of the colony, another skill- ful engineer found, with a party of colonists, his way to the opposite port of the sea-shore, the party did not venture to go back the same route, but rather chose the way by sea to Laguayra, from there to Caracas and back to the colony, a very circuitous route certainly. Such is the nature of this mountain region, with its precipices, waterfalls, deep ravines, and its dense, almost impenetrable primeval forests. Shortly after arriving in Colonia Tovar, Fendler bought a small farm in 1854 for 47 dollars. He described his new home in his letter to Gray of 16 December 1854: “My cottage stands on a small hill which is projecting from the sloping side of a mountain overlooking the greater part of the Col- ony. On the slopes of this little hill we have made terraces planted with Musa sapientum, with apple trees, Palms (Oenocarpus utilis), and stately tree ferns 14 feet high. Near the brown polished stem of the Palm the clear arch of a fountain (9 feet high) glitters in the tropical sun sending unceasingly its sparkling little stream to the top of the young Volume 76, Number 1 1989 Todzia Fendler's Venezuelan 315 Plant Collections Palm. This fountain I made in a few days without outlay of money. Two pieces of the trunk of Cerox- ylon andicola served as pipes." Fendler clearly enjoyed Colonia Tovar: “A visitor who never before lived in a valley like this finds here many pecu- liarities of vegetation, surface and climate which make him feel that he is not far off the land of perpetual peace; for he has entered the happy region of the ferns, the 'tierra templada de los helechos.' There is no scorching summer's heat, no fearful winter's cold, neither tornados to dev- astate the country nor gales to blind the inhabitants with sand and dust or penetrate their clothes and flesh with piercing frost" [Fendler to Gray, 16 December 1854]. His years in the village were the most enjoyable time of his life, and later letters indicate that he very much would have liked to return there [Fendler to Engelmann, 20 July 1882, Trinidad ]. During his first year at Colonia Tovar, Fendler devoted much of his time to plant collecting. He wrote to Professor Henry: “In collecting botanical specimens, I have penetrated, without companion, the wilderness around in different directions, also that on the other side of the principal mountain range towards the sea, and can testify to the dif- ficulties and hardships which are met with in ex- ploring such a country . . . . In these woods, where the rays of the sun never touch the ground, there it is where moisture and a cool temperature reign forever. The trunk of every tree and its branches are covered with Ferns, Lycopodiaceae, Mosses, Hepaticae, Lichens, Orchids, Bromeliads, Araceae and besides Piperacae with many exogenous plants too numerous to mention” (Fendler, 1857). Fendler wrote in detail to Gray, who had offered to enlist subscribers for his sets of plants. “I have already 8 boxes full of dried plants. The most attention I have hitherto paid to ferns of which I have 255 species, most of them complete; other plants I have not yet enumerated. For the last four or five weeks I have been employed with arranging my collections but have not yet finished. The fine dry weather which is now approaching urges me again to renewed activity in the field. The woods here are very dense and impenetrable without a sabre. The neighboring country is much diversi- fied" [Fendler to Gray, 16 December 1854]. “Of Palms I have collected 6 species, of which 5 grow in the colony. Tree ferns 9 or 10 species. Cruciferae and Umbelliferae are represented only by 2 or 3 species. 1 do not intend to send plants until I can send something complete, and until I can ascertain the safest way to forward them" [Fendler to Gray, 16 December 1854]. Less than a year later, Fendler wrote: **Of flowering plants I have about 1,850 species, although my search after these may be called but a superficial one. I think from 800-1,000 more species might be col- lected and of ferns perhaps from 80-100 more" [Fendler to Gray, 25 November 1855]. In addi- tion to ferns and angiosperms, Fendler collected fungi for M. A. Curtis, a mycologist in the Caro- linas, lichens for Professor E. Tuckerman, a li- chenologist at Amherst College, and mosses for William Starling Sullivant, a distinguished Ameri- can bryologist in Ohio. In 1857, after collecting in Colonia Tovar for over two years, Fendler found it increasingly dif- ficult to find novel species. “In coming to a new country it is at first comparatively easy to make a living by collecting plants; for the collector can make use of all the different species that meet his eye, and can carry them home without the aid of other hired persons or beasts of burden. But after he has explored the neighborhood and is obliged to make extensive excursions of from 8-14 days or 3 weeks, the case is different, and he soon finds that his earnings do not come up to his expenses" [Fendler to Gray, 1 July 1857]. After collecting thoroughly around Colonia To- var, Fendler took longer excursions crossing *'the principal mountain chain in three different places. One from Maracai to Columbia [Puerto Colombia ] to the very margin of the sea; the other from Valencia to San Estevan within 3 miles of Puerto Cabello; the third from Petaquire to within a few miles of the sea-shore. The two first regions are W est, the third one East of Colonia Tovar. Besides these I have made a number of minor excursions into the neighboring valleys” [Fendler to Gray, 1 July 1857]. During these long excursions he re- flected: “The more I attempt to explore these re- gions the more am I convinced, that a great deal remains yet to be done with regard to discovering and making known the plants of this country. These extensive ranges of mountains with their innumer- able recesses and deep ravines, covered with the densest growth of primeval forest uninterrupted for more than 150 miles from East to West, have been in most places never been traversed by civilized men. When standing on some high mountain-peak and looking over a part of this territory, it needs no great power of imagination to be filled with a longing and an ardent desire to embark in enter- prises even of the most perilous kinds, in order to penetrate the unknown abysses and to bring to light the hidden treasures of vegetation. And when in such moments I compare my strength and m fast waning pecuniary means, which forbid to hire 316 Annals of the Missouri Botanical Garden a companion to help me carry the burden, then I feel somewhat akin to depression of mind which prompts me to leave the spot and retrace my steps homewards.” Because Fendler viewed plant collecting as a business, he was very concerned with the market- ability of his specimens, which were valued ac- cording to their origin, rarity, and completeness of identifications. Thus Fendler wished to have his plant collections be as rare as possible, as well as to have them determined. He was concerned that Karl Moritz, who had been living in Colonia Tovar for over ten years, would begin again to collect plants in his territory. “The present letter is chiefly written to make you acquainted with my intentions of sending the collections as soon as possible, that you may be enabled to correspond or to publish something to that account and secure me from 10- 13 subscribers in time, because Mr. Moritz, who is still here has sometime ago commenced again to collect ferns, which he intends to send at an early date to Germany (I think to Berlin). I have seen Moritz's own set of his former collections when he used to travel about the greater part of Venezuela viz: the Orinoco, the mountains of Merida, Cu- mana, Caripe and a great many other regions; but the number of all his species of ferns will hardly exceed 250 or 260, while I have already 314, of which at least 290 are collected at the Colony or from 4-8 miles around it. There are several regions not far-off, where I never yet have been and which promise a very rich harvest of new species. I think I could augment the number of species considerably and discover many more new ones if | am sure that they find a market on which I may rely. I am therefore anxious to secure subscribers for them; so that I need not fear competition and then I shall go at it with renewed vigour; and if my life and health be spared I think of bringing together a rather complete representation of the vegetation of this and other parts of Venezuela. When I came here, Moritz seemed rather surprised that I should go at collecting plants in a place which he thought of being thoroughly ransacked, and he said that it would be a hard matter to find any new species. He seems however to have altered his opinion in this respect, after I had been in the field for some time; for I showed him many a plant which was new to him” [Fendler to Gray, 25 November 1855]. Fendler’s Venezuelan collections surpass Moritz’s in quantity and quality (J. A. Steyermark, pers. comm.; A. R. Smith, pers. comm.). Plant collecting, however, was not profitable enough for Fendler to support himself and his in- valid brother. “Whenever I was engaged in sci- entific pursuits for any length of time I was soon obliged to go to work at some other more profitable business, although that business might not be in accordance with my inclinations. And now I find again that the little capital, which I had earned at Memphis during three years by distilling cam- phene, is rapidly vanishing, notwithstanding the most frugal mode of living. I am therefore under necessity to try my hand for a while at something else beside collecting plants, and have already com- menced to make experiments in brewing beer and making brandy; and shall be obliged (with regret do I say it), to spend most of my time behind the still . . . . By no means do I wish by the preceeding lines to convey to you the idea, that I am dis- couraged or that I have given up collecting plants. As long as strength and life and a few spare dollars remain with me I shall continue to do all I can for my favorite pursuit; and even now, whenever time and circumstances allow me to do so, I shall do it with the same zeal as I have done heretofore" [Fendler to Gray, 1 July 1857]. FENDLER'S COLLECTIONS In Venezuela Fendler collected under two num- ber series, one for the ferns beginning at no. 1 and ending at no. 500, and one for flowering plants, numbers 1-2,630. Sets of Fendler's Venezuela plants were purchased by the following people and institutions (the number before the name indicates which set went to that recipient). (2) Hooker (K), (3) Grisebach (GOET), (4) A. Gray (GH), (5) En- gelmann (MO), (6) Short (PH), (7) Charles Wyville Thomson (E), (8) Boissier (G), (9) De Candolle (G), (10) Oxford herbarium (OXF), (11) Harvey (TCD), (12) Delessert (C), (13) Martius (BR), (17) Eaton (YU), (18) Miss Elizabeth Morriss (?PHA), (21) Eaton (YU). It is not known whether sets 14-16 were sold at a later date, or whether they remained at GH. Sets 2-13 included ferns and phanerogams; sets 17-23 consisted only of ferns. The first and most complete set was retained by Fendler at first. Later he sold this first set of angiosperms to Gray. "My full set of Venezuelan plants contained over twice as many species as set No. 4, and therefore I hope that by the addition of those plants your herbarium would gain something. 1 would rather see them incorporated with your herbarium than with that of anyone else. The naming of the price of the lot I leave to you as you can judge best of their value, and I know that I am in good hands when I am in yours" [Fendler to Gray, 28 October Volume 76, Number 1 1989 Todzia Fendler's Venezuelan 317 Plant Collections m Choroni e bn Esteban Esmeralda i la Guaira Caraypca Petaquire = e dE Punta Maya ip Urbina petant R.

Ten cents per sheet was the usual asking price, although it was slightly higher for the orchids since they were often unicates. At times Fendler felt he was not justly compen- sated for his specimens. For example, Lindley thought the price too high. “If Dr. Lindley was advised to pay but £2 per 100 for my Orchidae, then I will ask nothing more, and he shall be very welcome to them if he finds them to be worth that much. But if on the contrary he finds that the greater part of them, from being common things, are of no use to him, which I am inclined to infer from his letter, then I should be very sorry indeed that I ever offered them to him. To me that would be at least objects of remembrance of the amount of labor, bestowed upon, and perhaps of an over- animated enthusiasm in searching for them” [Fen- dler to Gray, 27 March 1859, St. Louis ]. FENDLER's FIELD NOTEBOOK In 1859, Fendler sent Gray the field notes for his Venezuelan plants, retaining the information only on his personal set of specimens (set No. 1) [Fendler to Gray, 15 December 1859, St. Louis]. The field notes contain all dates and localities from which a particular species was collected, as well as elevation and notes about habit. Fendler numbered his plant collections according to the classification schemes presented in Gray's Botany of the North- Map of the localities in northern Venezuela where A. Fendler collected in 1854-1858. ern United States and Lindley's Vegetable King- dom rather than the order in which they were collected, as is usually done today. o obtain more complete sets of specimens, which could then be sold at a higher price, Fendler often applied the same number to specimens he believed to be the same species but were from widely distant localities. Fendler also attributed to the same col- lection number specimens collected on as many as five different dates. This was a common practice among professional plant collectors, particularly those working with Gray (Ewan, 1969), and a source of problems for plant systematists. The /n- ternational Code of Botanical Nomenclature (Burdet et al., 1983) states that an “isotype is any duplicate (part of a single gathering made by a collector at one time) of the holotype.” Since Fen- dler did not indicate on his specimens what specific date a particular sheet was collected, technically o isotypes can be designated. Of the 225 names in this list, 66 were collected on more than one date. Few taxonomists have previously been aware of this problem with the Fendler Venezuelan col- lections. LOCALITIES Almost all of Fendler's Venezuelan specimens bear blue labels imprinted at the top with “Plantae Venezuelanae” and “Prope coloniam Tovar legit 318 Annals of the Missouri Botanical Garden TABLE 1.

Fendler 1845-5” at the bottom. The collection number is usually on the label, although it occa- sionally is on a slip of paper attached to the plant. Apparently Gray had these labels printed as he did for Wright’s Cuban collections. Only the first set of Fendler’s specimens, now at GH, has any col- lection data on them. Although the labels indicate that the sets were collected near Colonia Tovar in the state of Aragua, they were in fact also collected in the state of Carabobo and in the Distrito Federal. Figure 3 maps the Fendler localities in northern Venezuela, and Table 1 presents a list of these localities. TYPE LIST Of Fendler’s 2,630. Venezuelan angiosperm col- lections, this study located records of 225 that have been designated as types. Since only the first of the 20 sets has collection data, full localities from the notebook are given for these types. In the following annotated list of angiosperm types based on Fendler Venezuelan collections, the num- ber in the parentheses refers to the number of dates listed in the notebook. The orchids, numbers 1,359-1,489 and 2,124-2,155, were not includ- ed in the notebook. The species names listed in Appendix I were gleaned mostly from the Flora de Venezuela and the Catálogo de La Flora Venezolana (Pittier et al., 1945-1947), as well as with the help of several specialists (see Appendix I). The current accepted names are given when known to me. Herbaria data were gathered from the original descriptions, the TROPICOS data base at MO, the specialists listed in Appendix I, and the author's search through the Volume 76, Number 1 1989 Todzia 319 Fendler's Venezuelan Plant Collections MO herbarium. Unfortunately, there is no record of the number of duplicates made of each collection number (although the number may be on the labels of set No. 1 at GH, as with the ferns (Smith & Todzia, 1989), and therefore there is no way to ascertain which specific specimens are at any one herbarium. Since GH received Fendler's first set of angiosperms, excluding the orchids which went to Lindley, there are probably specimens for all numbers there. However, only herbaria where a specimen is confirmed to be deposited are included in the list. Overall, Fendler's Venezuelan specimens are widely distributed in the United States and Europe. The following 18 herbaria are known to have some Fendler Venezuelan collections (Lan- jouw & Stafleu, 1957; pers. obs.): AMES, BR, BUF, C, CM, F, G, G-DC, GH, GOET, K, MO, NY, OXF, P, PH, S, and US.

ABSTRACT Augustus Fendler collected over 500 collection 2 of pteridophytes in Venezuela between 1854 and These collections are noteworthy because of the lar numbers thus far identified) among them. This Ios 1858. types (44 collection collections and a historical account of the collections, including a portrayal of Fendler's fascination with fe Augustus Fendler collected in northern Vene- zuela between 1854 and 1858, where he amassed important collections of angiosperms, ferns, fern allies, lichens, mosses, liverworts, and fungi. Al- though a general account of his Venezuelan col- lecting is given in the previous paper (Todzia, 1989), this article deals specifically with his fern collec- tions. Fendler’s pteridophyte collections are note- worthy because they represent the first intensive gathering of ferns and fern allies from the Coastal Cordillera of Venezuela, and because they are widely distributed. Consequently, they have become type specimens of a great many fern species. The fol- lowing account has been assembled with the aid of Fendler’s correspondence with Daniel C. Eaton and Asa Gray, at the YU and GH archives, respec- tively. Fendler’s Venezuelan fern collections as well as his sets of flowering plants were distributed by Asa Gray. As with the angiosperms, Fendler initially retained the first set for himself. In 1859 he re- ceived a request from Thomas Moore of the Chel- sea Botanic Garden for a set, but since Moore had access to William Hooker’s herbarium containing set 2, Fendler decided to sell his first set to Daniel C. Eaton, who was then a student of Gray. He did this because Eaton agreed to publish a list of these collections, and because the collections would then remain in the United States, where Fendler would have easy access to them. In a letter to Eaton, Fendler stated, “The only set remaining with me is set No. 1 which I used for comparison and in which I felt a pride and a pleasure to lay up not only the most complete but also the finest speci- mens selected from the rest. There was a time when I thought I could never part with these plants. In bringing them up from their hidden places I have neither shun danger nor travelling expenses, and it was chiefly the search after Ferns, whic induced me to cross the principal chain of the cordillera of the coast upon four different tracks. I therefore need not say how dear they are to me, and I never would have sold them to anyone except to a Botanist, who is able to make the proper use of them" [Fendler to Eaton, 24 January 1859, St. Louis]. Fendler went on to say, *For my part I have neither the necessary books, time, nor her- barium to do it. Great resources undoubtedly are necessary to determine, which of the species are new and which are not; for I have reason to believe that in works on Ferns, with many species, a critical and patient overhauling is very desirable, in order to disperse the existing confusion. | remember to have seen in one herbarium the same species under four different names, one of these specimens was even disposed of under a new genus” [Fendler to Eaton, 24 January 1859, St. Louis]. In total, Fendler sent Eaton close to 500 collection numbers ' We thank the archivists and librarians at the Missouri Botanical Garden, Gray Herbarium, and Yale University for aiding in finding some of the s M Steyermark, and H. van der ources used in this pape Werff concerning Fendler in Venezuela.

A year later, Eaton's dissertation was published (Eaton, 1861). Fendler, however, was not pleased with this work. In the following long passage, we can see what a keen observer Fendler was. “In regard to Mr. Eaton’s Filices I am sorry to say that I was very much disappointed. Being in possession of the names of Dr. Engelmann's set of ferns as determined by Prof. Mettenius,* I was able to compare them with those given by Eaton and find that the names of 146 sp. agree with those determined by Mettenius, while the names of 101 spec. disagree. I am not able to say who is in the right, but should be inclined to depend more upon the one that has the longest experience in the matter [Mettenius J. Such differ- ences of different authors are most discouraging to the student of botany and a severe drawback in the acquisition of knowledge. But what concerns me more immediately and of which I think I have reason to be solicitous, is the readiness with which Mr. Eaton throws different, quite distinct, species under one and the same name. I regret this, the more it may be inferred as if I purposely manu- factured species for the sake of selling one and the same species over again under different numbers. Having pointed out in Mr. Eaton's set some of the more obscure characters of many species very much resembling each other, I thought I had done something to prevent mistakes. It always seemed to me, that authors who only see 1 or 2 dried specimens of each species ought to pay at least some slight regard to the opinion of a collector who had the best opportunities, and for 4 years availed himself of those opportunities to study the habits of the different ferns, and to observe them in their growing state in the different phases of their growth, not on single specimens or in single localities only, but in hundreds of different places and individuals." Fendler continued: “There may be a dozen species about which I was rather doubtful, but all the rest I consider genuine species; and as soon as I shall have time to examine Dr. Engelmann's set, I shall endeavor to point out the differences in species considered the same by Mr. Eaton. That even the g H. Mettenius (1823-1866), Ne pteridol- t B. * Geo ogist, ie fern herbarium is now mostly most experient [sic] authors on ferns may some- times take 2 different species to be one and the same is proved by Prof. Mettenius calling No. 161 'a young specimen of 162.' Now the former (No. 161) is not only different in form but has also 2 to 3 oval tubers, all the fronds die at a certain season of the year, and new fronds make their appearance rather suddenly but not before the commencement of the rainy season; the latter (No. 162) is a perennial plant to be seen at all times of the year and never possessing tubers” [Fendler to Gray, 24 March 1868, St. Louis]. In fact, these two numbers do represent two species (Appendix I), and Fendler was correct. Nevertheless, Fendler's friendship with Eaton grew, as evidenced by Fendler's 15 letters to Eaton written from Trinidad between 1878 and Fendler's death in 1883. In Trinidad, as in Venezuela, he seems to have been preoccupied with collecting ferns and seems to have particularly relished dis- cussing his Trinidad fern collections with Eaton. Fendler, however, much preferred Venezuela over Trinidad and in his letters to Eaton, Engelmann, and Gray from Trinidad, he often mentioned how much he would like to return to Colonia Tovar. In his last letter to Eaton before his death, Fendler stated, “I long for the cool alpine air (damp though it be) for the deep shades and the eternal silence of those primeval forests, where a quarter of cen- tury ago my footsteps were wandering in search of the treasures of botany—especially those of ferns—again to go and see them, and to draw them forth from out their hiding places in the deep dells, or to bring them down from the mountain's high summit” [Fendler to Eaton, 15 June 1882, Port- of-Spain, Trinidad]. At 69, forever the fervent collector, Fendler asked Eaton if the professor could find subscribers to about 40 sets of Venezuelan ferns [Fendler to Eaton, 15 June 1882, Port-of- Spain, Trinidad]. Fendler often wrote to his cor- respondents that he longed to return to the “land of perpetual peace ... the happy region of the ferns." FENDLER'S FERN NOTEBOOK AND COLLECTIONS Fendler's field notebook in the GH archives is not chronological and consecutive, but rather a catalog of species in taxonomic order. Thus, the number sequence begins with 1 (Marattiaceae), proceeds through the more primitive fern families (Osmundaceae, Schizaeaceae, Hymenophyllaceae, Gleicheniaceae, Cyatheaceae), and then continues with the more advanced ferns, genus by genus, up to number 324. Numbers after 324 were collected Annals of the Missouri Botanical Garden after a trip to the United States and after he had distributed some of his material. It is obvious that the notebook was compiled after many of the col- lections had already been made and put into se- quence. Fendler combined collections made on dif- ferent dates and at different places under a single number. For example, Fendler 6, Anemia villosa, was collected on nine different dates (according to data on the sheet at YU) and most likely at several different localities during the years 1854, 1855, and 1856. Fendler probably revisited many collection sites in an attempt to amass additional material of a given number, because he intended to collect in large sets for sale to as many individuals or herbaria as possible. It appears that he tried to collect in sets of 20, although he gathered 40 sheets of Fendler 23, Trichomanes reptans. 'The number of collections appears in the upper right-hand cor- ner of the labels on sheets at YU but does not appear on the labels of Fendler collections in other herbaria. In some cases, Fendler kept an account of material of varying stages, e.g., he collected 26 young and 12 old specimens of Marattia laevis (Fendler 3). In other instances, he recorded the number of specimens in different categories, e.g., he collected 20 specimens of no. 94, Paesia glan- dulosa, and 5 more with the rhizome. For many numbers through about 324, specimens were col- lected in rather large sets. Thereafter, the sets were generally much smaller, often only a few sheets. Most of the numbers after 324 were gathered in the years 1855 to 1858, whereas most collections of the numbers before 325 were made in 1854, with additions to the set made in 1855 and 1856. Fendler's keen eye is evident by the fact that, even though he often collected the same species (or number) at different times and/or localities, there are very few mixed gatherings. He must have had a very discriminating eye for differences. When in doubt, he often gave aberrant collections Greek letter designations a and 8 under the same number, or labeled the additions “ad 56”; sometimes these represent noteworthy taxonomic variations (occa- sionally different species), sometimes only forms of little taxonomic significance. The following are tax- onomically mixed collections: 16, 31, 64, 72, 73, 83, 98, 117, 143, 179, 181, 185, 187, 221, 224, 232, 2587, 259, 293, 294, 322, 324, 364, 378, 380, and 473. Some of these probably rep- resent inadvertent mixing or misnumbering, where- as others are in large genera of great taxonomic difficulty, e.g., Elaphoglossum, Thelypteris, and Selaginella. Fendler's collection numbers range from 1 to 499. Of these, 44 are thus far identified as types. We have seen specimens or notebook information for all numbers except 2 and 339. In addition, neither we nor Eaton (1861) saw specimens num- bered 337, 345, 346, 384, 392, 401, 427, 442, 458, 462, 478, 484, or 490. The notebook at Harvard contains entries for numbers 58 to 499; inexplicably, the early numbers are missing. Because Fendler gave the same collection num- ber to plants collected at different times and lo- calities, it often is impossible to determine the lo- cality and date of a particular specimen. In a few cases there is only a single date on the specimen and in the notebook. In the list that follows (Ap- pendix I) dates are given only where there is reasonable certainty that the entire gathering was made on a single date at a single place. For those numbers that were collected on more than one date, we give the total number of dates (as indicated from the notebook and on the specimens at YU). For all numbers, the size of the set, when known, is given. Fendler's Venezuelan pteridophytes were widely distributed, and specimens have been located in the following 16 herbaria: B, BM, BR, CU, F, G, GH, GOET, K, MO, NY, P, PH, S, US, and YU.

Seeds black, colliculose, 2.5- 3 mm across. Known only from the type locality, this species is easily distinguished from other yellow-flowered South American Echeandia species by the com- bination of scaled filaments, many branches, and the storage organs developing at some distance from the corm. It is unusual for yellow-flowered species to occur at such low elevations. — Robert William Cruden, Department of Bota- ny, University of lowa, lowa City, lowa 52242, U.S.A SOLANUM TOLIAR AEA, A NEW SPECIES FROM MADAGASCAR Solanum toliaraea D'Arcy & Rakotozafy, sp. nov. TYPE: Madagascar: D'Arcy & Rakoto- zafy 15460 (holotype, MO; isotypes, K, P, TAN) rutex armatus spinis brevibus validis rectis, foliis ro- tundis parvis stellato-tomentosis; flores solitari v-geminati, calyce inermi sed in statu fructu accrescenti, echiniformi, acinum tegenti Slender, branched shrub or tree to 3 m tall; twigs slender, at first appressed tomentose with reddish hairs, soon puberulent with reduced buff- colored trichomes and deeply furrowed, armed with short, stout-based, puberulent spines. Leaves mostly paired in fasciculate short- shoots, entire, rotund, apically rounded, ed rounded, truncate or cordate, mostly 8-20 m long, thick, felty with dense short-stalked, elate hairs, the costa evident, the minor venation o nearly straight, scure; peduncles canaliculate adaxially but alten appearing terete because of the dense tomentum, mostly 5-10 mm long, with occasional small straight spines. Inflorescences solitary flowers or paired fas- cicles from the leafy short-shoots; pedicels resem- bling the petioles but somewhat longer. Flowers with calyx ca. 4 mm long, lobed about 44 way down, the lobes convex, obtuse, tomentose, un- armed; corolla pale purple, mauve, or white, ca. 10 mm long, lobed 44 way down, tomentose outside except on the membranaceous inter-lobe fringing areas, glabrous within, the nervature drying con- spicuous within; stamens 5, equal, the anthers yel- low, slender, 5 mm long, opening by minute ter- minal pores; ovary glabrous, drying somewhat lobed, the style slender, exserted slightly beyond the sta- mens, with a few short, gland-tipped simple hairs near the base. Berry green, juicy, 4-lobed, ca. 5 mm diam., entirely but loosely enveloped in the calyx, the spiny, accrescent calyx echinoid, subglo- ANN. seeds (Descoings 2375) compressed, dark, 2.5 mm long bose, ca. 2 cm diam.; At time of flowering the calyx of this species is devoid of spines, in contrast to its copiously spiny, echinoid condition when in fruit. Collections of this species were first confused with Solanum dubium Fresen of Ethiopia, which has similar spiny accrescent calyces, but that species is herbaceous and has much larger, lobed leaves. The species described here differs from the other two arborescent species of southwestern Madagas- car in its accrescent, spiny calyx and in its rotund, concolorous leaves. Solanum toliaraea is sympat- ric, at least in part, with other arborescent sola- nums, S. bummeliifolium Dunal and S. heineanum D'Arcy & Keating, which differ in usually spineless calyces and porrect, scutellate hairs. Solanum toliaraea was seen as scattered indi- viduals in didieriad woodlands of southwestern Madagascar. Most collections were made from plants growing on sand near the coast just north of the major city of Tulear and hence just north of the Tropic of Capricorn. The name toliaraea is derived from the Mala- gasy spelling for the city of Tulear. e seen. ll aa TULEAR (Toliary): bush a Didie sur dunes, embouchure de Fiherenana, Be- landa, Nox 1956, Bokir 10472 (MO, P); scrub forest on pure ei sand, 8 km N of Tulear on road to Morombe, 5 1975, I 30778 (MO); road to 5 km N of Belalanda, 17 May 1983, D'Arcy & Rakotozafy 15460 (MO, K, P, TAN); Sable, Manombo, région de Tuléar, Decary 16214, 18714 (P); route de Manombo sur sable, 7 Jan. 1957, Descoings 2375 (MO); bush á Didierea sur dunes, embouchure de Fiherenana, Bela- landa, May 1960, Keraudren 690 (P); bush à Euphorbiés, route de Monombo, prés de la cóte, environs de Tuléar, 3 Nov. 1960, Léandri & Jean de Dieu 3627, 3635, 3804 (P); thorn scrub of Euphorbia and Didierea on Missouni Bor.

NOTE CONCERNING FESTUCA HENRIQUESII (GRAMINEAE) IN NORTHERN PORTUGAL The species Festuca henriquesii Hackel (Gra- mineae), first described in 1883, is endemic to Portugal. In various floras and subsequent publi- cations, namely Coutinho (1939), Sampaio (1946), Litardiére (1952), and Tutin et al. (1980), the location of this species has been given as restricted solely to the Serra da Estrela, a mountain range in northeastern Portugal. Little information is avail- able concerning its ecology, except that specimens have generally been collected from high places in this mountain range. Recently, however, I recorded this species from a grassland area in the Serra do Gerés, in northern Portugal (Hale, in press). I had believed that this was the first record for the species outside of the Serra da Estrela range. The location, in grazed grassland within an area generally of ericaceous shrubland, is known as ““Lagoas” because of two small nearby lakes. The plants were growing on an acid soil over granitic parent material at an altitude of 1,150 m (grid reference X326 071; Carta Militar 31). Further investigation revealed, however, that this record for the species in the Serra do Gerés was not unique. Besides two records from the Serra da Estrela, three specimens of F. henriquesii exist in the Herbarium of the Institute of Botany “Dr. Gonçalo Sampaio” in Porto, collected from the Serra do Gerés and nearby areas (Table 1). Despite the existence of these specimens, however, this species appears not to have been previously re- ported from these mountain ranges. It is clear from these records that Festuca hen- riquesii is not restricted to the Serra da Estrela; the range includes the serras of Gerés, Peneda, and Barroso. The species might be a glacial relict rined to a few mountain ranges and not noticed ide of the Serra da Estrela; alternatively, its dictation may be expanding. In view of the apparently discontinuous distribution, these other mountain ranges being nearly 200 km from that TABLE 1. F. henriquesii records outside Estrela.

I thank the staff of the Herbarium of the In- stitute of Botany “Dr. Gonçalo Sampaio,” Porto, for confirming the identification of the “Lagoas” specimen and for access to the previous records of the species.

PASSIFLORA CITRINA, A NEW SPECIES IN SECTION XEROGONA (PASSIFLORACEAE), FROM MESOAMERICA The center of diversity for Passiflora L. subg. Plectostemma Masters sect. Xerogona (Raf.) Killip is in northern Central America, where at least six species occur in Guatemala alone. The section is notable in the genus Passiflora for its unusual capsular fruit. Killip (1922, 1924, 1927) described five species of this section from Central America and southern Mexico that had been confused with P. rubra L. or P. capsularis L. Newly described here is the yellow-flowered P. citrina, yet another member of this section that has been hidden under misapplication of the name P. capsularis. Passiflora citrina MacDougal, sp. nov.

Xerogona because of the sub- pentangular stem, absence of petiolar or laminar nectaries, absence or near absence of floral bracts, elongate fruits with six "keels, and seeds with a transversely grooved sclerotesta having a chalazal eak that is sharply angled towards the raphe. Mature fruits are unknown; however, a fruit that is probably of full size with nearly mature seeds is found on the isotype at NY. On a different collec- tion, Howard et al. 637, the collector observed the fruits to be “red,” but no fruits are included with the specimens. It is unknown whether the fruit 356 Annals of the Missouri Botanical Garden of this species is six-valvately dehiscent, as is usual in the other members of sect. Xerogona. Passiflora citrina is remarkable for its elongate yellow flowers that are tubular in the basal half. The androgynophore is distinctively long and sets the species apart from all other members of sect. Xerogona except P. sanguinolenta Masters from southern Ecuador. Though very similar to P. ci- trina, P. sanguinolenta has nearly triangular stems, peduncles solitary at the nodes, pink to purplish red flowers that retain a diminutive second series of coronal filaments, and seeds with slightly ru- gulose ridges. Both species have slightly elongate flowers of similar morphology, flowers that have departed from the usual bowl-shaped hymenopter- an-adapted groundplan in sect. Xerogona (Lind- man, 1906) by reduction and fusion of the coronal filaments and partial connation and adnation of the perianth. In P. citrina the sepals are free from each other to within 2-6 mm of their bases, but they are submarginally adnate to the edges of the petals; the petals, in turn, are adnate to the connate portion of the coronal filaments. The net effect is a cylindrical structure formed by the adnation of the basal half of the perianth to the tubular and basally connate coronal filaments. The coronal fil- aments are free only in the distal 3-6 mm and are usually not visible on herbarium sheets without dissection. In dissected and living specimens, I could detect no trace of a second series of coronal fila- ments near the operculum. The derived floral morphology of P. sanguin- olenta is related to a shift in pollinators: the species is primarily hummingbird pollinated in its native habitat (C. Hofmann, pers. comm.). It is probable that P. citrina has also shifted away from polli- nation by hymenopterans. The butterfly Heliconius charitonius was ob- served using MacDougal et al. 3048 as a host lant. Floral bracts are fundamentally absent in P. citrina, but in Molina 6510 the peduncles occa- sionally bear a single bract at the apex. This species was first identified as undescribed while the author was a National Science Foundation Fellow at Duke University, and I gratefully ac- knowledge the financial support of the NSF, the assistance of the curators from the herbaria cited above, and Donald E. Stone for inspiration and guidance during my doctoral studies.

Mature fruits, showing pattern of ridges on epicarp. Volume 76, Number 1 1989 Notes 359 Stryphnodendron porcatum is probably most closely allied with S. guianense (Aubl.) Benth. subsp. glandulosum Forero, known from Peru, Bolivia, and Amazonia in western Brazil, which has similar pubescence of foliage, including the tuft of hairs near the base of the blade, and densely pilose ovary. In S. guianense subsp. glandulosum, however, the calyx and corolla are short-puberulent exter- nally, whereas in 5. porcatum the calyx and corolla lobes are densely pubescent with longer, golden hairs, while the corolla tube is nearly glabrous with scattered golden hairs. The typical subspecies of S. guianense, which ranges widely in Amazonia and the Guianas, lacks the tuft of hairs at the base of the leaflet blades, and all floral parts are glabrous. e most distinctive feature of 5. porcatum, which readily separates it from all other species in the genus, is the striking ornamentation of the legume, an irregular chevron-like pattern of ridges on the surface of the valves. The specific epithet refers to this sculptured surface of the fruits (Latin orca — *'ridge between two furrows made in plow- ing”; Stearn, 1966). Some individuals of S. porcatum are evidently female-sterile; the flowers of Palacios 1369 com- pletely lack pistils. To our knowledge, this is the first published report of the genus Stryphnodendron for Ecuador. No other species are known to occur sympatrically with S. porcatum in the Amazon region of the country. Stryphnodendron porcatum occurs on rich silty alluvial soils of river floodplains, and in Amazonian Ecuador, on upland Oxisol hills up to 1,500 m on the lower slopes of the Andes. In primary forest it attains a height of 40 m with a diameter at breast height of 70 cm. In the region around Coca, Napo Province, Ecuador, 5. porcatum is also frequent in secondary forests and is often left in pastures after the surrounding forest is cut. The sweet pulp surrounding the seeds is similar to that of Prosopis and Gleditsia. Several trees at the INIAP-Payamino agricultural experiment sta- tion near Coca stand in experimental pastures es- tablished for raising tropical hair sheep. The sheep eat with great relish the Stryphnodendron pods that fall to the ground, apparently attracted by the sweet pulp. The new species therefore shows some promise for inclusion in agronomic trials as part of the agroforestry and silvo-pastoral production sys- tems involving sheep, pastures, and forage legumes now being developed for and implemented by set- tlers in the Napo region of Ecuador. The support of the U.S. Agency for International Development (USAID) and the Forestry Director- ate of the Ecuadorian Ministry of Agriculture, for the research in eastern Ecuador, is gratefully ac- knowledged. The authors thank Enrique Forero for bringing us together through correspondence, and Alejandro Suárez for preparing the illustration. LITERATURE CITED MIR E. M. Stryphnodenron (Fabaceae: Mimoso- l.

A NEW SPECIES OF HYBANTHUS (VIOLACEAE) FROM PANAMA Hybanthus is a very poorly known genus of 150 species of herbs, trees, and shrubs from the Old and New World. The last synopsis of the genus throughout its range enumerated 32 species in the New World (Melchior, 1925); Morton (1944) pro- vided the most recent synopsis of the Central Amer- ican species.

(Available from Dr. L. E. Mora-Ose- jo, Academia Colombiana de Ciencias Exactas, Fisicas y Naturales, Apartado Aéreo 44763, Bogotá D.E. 1, Colombia.) Morphological, Autecological and Systematic Studies in Angiosperms is an important addition to the increasing botanical literature of high sci- entific quality being produced in Latin America. It has been published by the Colombian Academy of Sciences as the first volume of a new series called “Serie Jorge Alvarez Lleras.” The actual text is 188 pages long, with 75 figures, including several color photographs, and a bibliography with over 90 citations. The text is divided into two parts. The first part deals with the morphological and autecological studies and includes five chapters (1— 5), while the second deals with the systematic stud- ies and is made up of one chapter (6). The author indicates that one of his objectives is to present to a broader audience the “typolog- ical method, which has been developed in Ger- many but is not well known among Spanish- and English-speaking phytomorphologists. In the first chapter he discusses the general principles of the typological method, including such concepts as ho- mology, position, continuity, similarity, etc.; the procedures employed in the study of specific prob- lems; the contribution of typology to our under- standing of the organization and architecture of the angiosperms; and the relationship of typology with taxonomy and phylogeny. In Chapter 2, the typological theory and its relation to the evolution of the inflorescence is discussed. Chapter 3 deals with new concepts developed by the author on the diversity and evolution of organizational patterns found in the floral meristems in angiosperms, based on his observations of a number of families, in- cluding Melastomataceae, Araliaceae, Bignoni- aceae, Asteraceae, Cyperaceae, Juncaceae, Po- aceae, Bromeliaceae, and Scheuchzeriaceae. Chapters 4 and 5 deal with the author's original typological studies in Lilaea, Triglochin, and Scheuchzeria, which include the study of the ar- chitecture of the meristem and its correlation with the reproductive strategies of these plant groups. In Chapter 6, Mora-Osejo gives an example of the applicability of the typological method to the taxo- nomic study of Oreobolus R. Br., a genus of Cy- peraceae. There are several aspects of this publication that I find outstanding, the most important being the thorough discussion of the theory and practice of the typological method. The author explains how this method allows for a comparative analysis of architectural patterns in plants as opposed to a purely descriptive analysis. The method also allows for interpretation of information derived from the detailed analysis of plant structures through the understanding of the interconnections among them. At the same time, it provides valuable tools for understanding adaptations to the environment as well as reproductive strategies in angiosperms. Aside from its obvious scientific value, the reader is also very favorably impressed by the good quality of the printed product and by the quantity and quality of the illustrations, which include numerous schematic representations, color and black and white photographs, details of plant parts, and more. The volume is a substantial contribution to our understanding of this important subject, as are most of Professor Mora-Osejo's publications. His study of the biology of the Haloragaceae, published as part of his treatment of the family for the Flora de Colombia, is another example of his scientific excellence. It is to be expected that this volume will be given proper consideration by phytomor- phologists in the United States and in Latin Amer- ica. Its contents are well worth careful study. This work is the result of many years of careful research by one of Latin America's most prominent scien- tists.— Enrique Forero, Missouri Botanical Gar- den, P.O.

Wiersema for his publication “A Monograph of Nymphaea Subgenus Hydrocallis (Nymphaeaceae)," which appeared in Systematic Botany Monographs, volume 16. This monograph is derived from a Ph.D. dissertation submitted to the University of Alabama, under the direction of Dr. Robert R. Haynes. Dr. Wiersema based his classification on numerical taxonomy, scanning electron microscopy of seeds and pollen, chro- mosome numbers, floral biology, artificial hybrid- ization, flavonoid chemistry, and general mor- phology. Fourteen species are recognized in the subgenus, which is restricted to the American trop- ics and subtropics, and one new subspecies is pro- posed. This Award is named for Jesse More Greenman (1867-1951), who was curator of the Missouri Botanical Garden Herbarium from 1919 until 1943. A cash prize of $250 is presented each year by the Garden, recognizing the paper judged best in vascular plant or bryophyte systematics based on a doctoral dissertation that was published during the previous year. Nominations for papers published during 1988 are now being accepted for the 21st annual award, which will be presented in the summer of 1989. Reprints of such papers should be sent to: Green- man Award Committee, Research Division, Mis- souri Botanical Garden, P.O. Box 299, St. Louis, Missouri 63166-0299, U.S.A. In order to be con- sidered for the 1989 award, reprints must be re- ceived by June 1, 1989.

Barrington? ABSTRACT A taxonomic history for the fern genus Polystichum in Latin America and an analysis of the vi dein characters at the species level in the genus provide the context for the recognition of new and overlooked taxa. Three new species are described from Latin America, and a new combination is provided for a Polystichum species from the southern Andes In the course of preparing a treatment of the genus Polystichum for the Flora Mesoamericana, I have discerned a set of new and neglected species from Central America and the northern Andes, which I report here. The species now included in the genus Polystichum have only once been in- cluded in a monograph (Mettenius, 1858); there has been no modern monographic work on the genus in the New World. An inquiry into species and speciation phenomena in Costa Rica (Barring- ton, 1985a, b; Barrington, et al., 1986) has led in turn to an inquiry into the significance of hybrids with respect to species concepts in the ferns (Bar- rington et al., in press). I report here on the mor- phological characters important in distinguishing species of Latin American Polystichum. This re- view of characters provides the context for the descriptions of species, which make up the central contribution of this work. TAXONOMIC HISTORY The genus Polystichum Roth, terrestrial ferns characterized by fastigiate leaves with inequilateral leaf segments and peltate indusia (when present), is prominent and diverse in montane regions 'T thank Luis Diego Gómez P. for his energy and support of my fieldwork in the Sierra Talamanca, Steven R Hill for his critical reading of the Latin descriptions, and Lynn Bohs for her thorough review of the manuscript. Several nomenclatural and taxonomic problems were resolved with Rolla Tryon's help. The curators of the following herbaria supported this project through loan of materials: A, AA U, CR, ENCB, F, GH, MO, NY, UC, US, USNA, .

GARD. 76: 365-373. 1989. 366 Annals of the Missouri Botanical Garden throughout the world. The generic name originates with Roth (1799), but it was K. B. Presl (1836) who first circumscribed the genus as it is now recognized. The most important influence on the taxonomic history of Polystichum was the treat- ment of W. J. Hooker (1862), in which most of the twice-pinnate taxa in the world were combined into one species. As a result, the morphological and taxonomic diversity of species was left un- studied by the otherwise productive taxonomists of the late nineteenth century. Christensen (1906) maintained Hooker's counterproductive species concept in Polystichum, which has perpetuated the tendency for taxonomists to ignore the diversity of twice-pinnate species. Christensen did recognize 4l forms, many of which were associated with names whose types represent distinct species. atin America and eastern Asia are the two centers of diversity for the genus Polystichum. Although the diversity and biology of species are well known in Asia (Tagawa, 1940; Daigobo, 1972), we know little about the genus in the New World tropics. Maxon (1909) was the first to recognize natural species in the American tropics, but his work was confined to the West Indies. Only re- cently (A. R. Smith, 1981; Stolze, 1981) has sim- ilar progress been made in defining the continental species. In the past few years, the extent of the taxonomic problem has become clear with the dem- onstration of extensive hybridization and allopoly- ploidy in the American tropics (Barrington, 1985a, " popa et al., 1986). I reviewed the present mic status of the genus Polystichum in Latin America (Barrington, 1985c). MORPHOLOGY The analysis leading to the descriptions of the new species provided here and the work on hy- bridization and polyploidy have revealed the most useful characters for delineating Polystichum species in Latin America. Since there has been no previous morphological review for the genus in the Neotropics, I provide an analysis of the important characters for Polystichum. I hav mented on ontogenetic and environmentally in- duced variation, which is unusually confusing in the genus also com- INDUMENT Indument in Polystichum consists entirely of scales and scale homologs (squamules and micro- scales); true hairs, bristles, and spines are absent, at least in Latin American species. The general form, texture, and frequency of scales are impor- tant in delineating taxa of Polystichum. Particu- larly important are histological features of the scales: they may be conform (sensu Tryon, 1970) or they may have a margin of cells different in shape and orientation from the scale body. Scale color is im- portant too, although variable with position on the plant and age of the plant. Tagawa (1940) con- tended that the smallest scales on the abaxial lam- ina surface (the microscales) are important in de- fining subgeneric groups in Polystichum. In Latin America, variation in microscales is extremely con- servative, consistent with Tagawa's contention. Most species have the acicular microscales typical of sect. Metapolystichum I have followed Smith (1981) in describing the processes that arise from the edges of scales and squamules as cilia, although this is an oversimpli- fication. [n fact, scales and squamules bear a con- tinuum of processes from cilia (long and delicate) to setae (short and stiff). I have chosen to call all of these processes cilia and use adjectives to de- scribe their length and stiffness. The kinds and proportions of these cilia on the different scales and squamules are important taxonomic characters in Polystichum. LAMINA The dissection and texture of the lamina provide critical characters for distinguishing species of Po- lystichum, although they are phenotypically and ontogenetically variable. Particularly confusing is the tendency for older plants to have larger, more dissected leaves. Nevertheless, species can be cir- cumscribed within the context of the ontogenetic variation encountered. In addition, the shape, angle of attachment, and revoluteness of leaf segments (pinnae and pinnules) are all important, although phenotypically variable (especially revoluteness). Development of the spinules (extensions of vein tips) varies among species. The complex interaction of ontogeny, environment, and genotype that shapes Polystichum leaves perhaps explains the recog- nition of large, poorly resolved taxa by both Hooker and Christensen. SORI AND SPORANGIA The placement of the sorus relative to the vein tips is important in Polystichum, even though it is variable across a segment. Indusium presence or absence is an important character, although the indusium is sometimes pal in ee Po- lystichum species. In addition, , Shape, and histology of the inden vary among, but usually not within, species. Color is sometimes use- Volume 76, Number 2 1989 Barrington Polystichum ful but is variable with age. The design of the perispore is usually constant within species. Color of the indument is a useful character in Polystichum, as in many ferns. The color names used in the descriptions here are the National Bu- reau of Standards color names as defined in Na- tional Bureau of Standards Special Publication 440 (and its predecessor, Circular us iir by comparison of indument with the BS Color-Name Chart (a supplement to D Special Publication 440), which is a partial set of color chips representing the color centroid. I standardize color terminology in this way, rather than using the Ridgway-Dade terminology and standardization (Stearn, 1983), because those color names are much less familiar, and the color chips on which they are based are much harder to locate. Indu- ment is variable and systematically useful in all three dimensions of the color centroid (hue, value, and chroma); it is also variable in these dimensions with position on the plant and age of the individual. HYBRIDIZATION AND SPECIES DEFINITION Hybrids between the new Costa Rican species described here and several other species were en- countered during fieldwork. Several of these hy- brids have been described elsewhere (Barrington, 1985a, b). All of them meet two criteria of hy- bridity: intermediacy and spore irregularity. Since all of the hybrids have irregular spores, they are probably sterile and hence provide evidence of species-level divergence between their progenitors (Barrington et al., in press). This evidence provides a first working hypothesis for species definition in tropical American Polystichum and the basis for recognizing the new species described here.

Polystichum rachichlaena is notable for the large size (over 1 mm diam.) and persistence of its indusia; it also has petiole scales virtually devoid of cilia. The lamina and sorus of P. concinnum are similar to those of P. erythrosorum, but the petiole scales of P. erythrosorum are er, marginate, and strongly bicolorous (basally lustrous and black with brownish orange borders). In addition, the long, delicate cilia of P. concinnum are lacking in P. erythrosorum, and the small distal cilia are not dark and indurated as they are in P. concinnum. Polystichum concinnum is well represented in her- baria; it has been determined most often as either Polystichum muricatum (L.) Fée (which differs in having short petiole-scale cilia) or Polystichum ordinatum (Kunze) Liebm. (which differs in having narrow leaf bases and strongly bicolorous petiole scales with thick bases). David B. Lellinger, of the United States National Herbarium, first distinguished P. concinnum and coined its species epithet.

Polystichum talamancanum is prominent in rock clefts and on roadbanks along the Pan-American Highway above treeline in Costa Rica. It tends to have more patent pinnae and flat pinnules in shade. The indusia are variously developed: some sporophytes never have indusia; others regularly produce spatulate indusia. This variation complicates discrimination of P. con- cinnum, P. talamancanum, and their backcross hybrid. Polystichum talamancanum, endemic to the region above treeline in the Sierra Talamanca, may be confused with Polystichum orbiculatum and allied taxa. Polystichum orbiculatum in Costa Rica has flaccid petiole scales that are paler and more orange than those of P. talamancanum and has long, delicate cilia throughout. In addition, P. or- biculatum has apically as well as laterally revolute pinnules, and it is never indusiate, whereas talamancanum has pinnules that are revolute only laterally and sometimes has indusia. n the Andes from Venezuela to Peru, an array of plants has been collected from those like P. orbiculatum in Costa Rica to plants much like P. talamancanum. The Andean plants most like P. talamancanum differ from it in lacking indusia and having broader, larger petiole scales with nar- row white borders bearing short, stiff cilia; if they are hybrids, their progenitors differ from those of P. talamancanum and are best determined as P. pycnolepis (Kze. ex Kl.) Mett. The taxonomy and evolution of P. orbiculatum and its allies in the Andes is a complex and intriguing problem: the hybrid origin of P. talamancanum on the Sierra Talamanca is likely to be one part of a much broader, Andean set of evolutionary events, in- cluding the origin of P. orbiculatum and other high-altitude Polystichum species.

ADDITIONS IN MAXILLARIA FROM THE VENEZUELAN GUAYANA' Germán Carnevali? and Ivón Ramírez? ABSTRACT T w Maxillaria species from the Venezuelan Guayana, M. foldatsiana and M. santanae, are described and illustrated. One highly variable species, M. auyantepuiensis, is discussed, and a new subspecific taxon is proposed. Maxillaria tenuis is noted as a new record for the Venezuelan flora. Maxillaria Ruiz & Pavón is the largest genus of the subtribe Maxillarinae, with about 400-4 species ranging from Mexico and the West Indies to southern Brazil. The genus reaches its highest development in the Andes, but le America, southern Brazil, the Amazonian a and the Guayanas are well represented. The species of Maxillaria usually grow in places of heavy rainfall but often can be found in places with a marked dry season. They grow in almost every vegetation association and at any elevation from sea level to near the snow line but are especially common in rainforest or cloud forests at 500-2,000 m. Most members of the genus are epiphytic, but it is not unusual to find lithophytic or even terrestrial species, particularly in open, humid places. The vegetative morphology is very variable, ranging from tiny plants less than 1 cm high to plants 2 m long. They are usually pseudobulbous, sympodial plants, but pseudobulbless, almost monopodial species are not unknown. Rhizomes may be short, making caespitose plants, but many species have long creeping primary stems; these may be appressed to substrate for their entire lengths or only attached at their bases to the host, making erect, ascendent, or pendulous plants Maxillaria is characterized generically by sol- itary flowers originating from the pseudobulb base or from the internodes of the rhizome (the Cama- ridium alliance). The flowers may be minute to very large and showy and are variable in many respects, although the column is always basally produced into a more or less well-developed col- umn-foot to which the labellum is hinged. Orni- thidium Salisb. has a rigidly attached, unhinged labellum, and thus we feel it should be recognized, even though many authors do not do so. As a member of the subtribe Maxillarinae, all Maxil- laria species have four dorsiventrally flattened pol- linia in two unequal pairs, more or less well-de- veloped, usually semilunate viscidium, and variously sized and shaped stipites or no stipe at a In Venezuela there have been recorded about 75 species of Maxillaria, of which 47 are known in the Venezuelan Guayana. All major groups with- in the genus are represented in southern Venezuela. In terms of numbers of species, Maxillaria is only surpassed in the Venezuelan Guayana by Pleu- rothallis R. Br. (ca. 57 species) and Epidendrum L. (ca. 51 species). The next-largest genus is Oc- tomeria R. Br. (ca. 29 species).

Apparently epiphytic, erect herbs, 27-30 cm high. Rhizome abbreviated with aggregated pseu- dobulbs. Pseudobulbs narrowly ovoid, 4.7-5 c long, 1.3-1.6 cm wide at their broadest, mono- phyllous, concealed by appressed, scarious sheaths. Leaves coriaceous, erect, narrowly elliptic, acute, basally attenuate into a subcylindric pseudopetiole 4-4.5 cm long, leaf total length 23-24.5 cm, the blade 18.5-20 cm long, 2.3-2.6 cm wide. Inflo- rescences originating from the pseudobulb base, flowers solitary; peduncle subterete, entirely con- cealed by 4-5 tubulose, scarious sheaths, 3-5 cm long. Flowers medium-sized for the genus, appar- ently vertically erect. Perianth segments scarcely open. Floral bracts elliptic, acute, 1.4-1.5 cm long, 0.4-0.5 cm wide. Pedicellate ovary apparently subcylindric, 15-17 mm long. Dorsal sepal nar- rowly oblong-elliptic, acute, 20-20.5 mm long, 4- 4.5 mm wide. Lateral sepals narrowly triangular, acute, 20-21 mm long, basally 3.5-4 Petals narrowly elliptic, slightly obovate, acute or narrowly obtuse, 19 mm long, 4-4.5 mm wide. Labellum parallel to the column, in general outline narrowly oblong, 17-18 mm long, 4.5 mm wide at its broadest, slightly pandurate-trilobate above the middle; central lobe elliptic, obtuse-rounded, slightly concave, 7 mm long, 2.5 mm wide, basally attenuate in a short unguiculus about 2 mm lon and wide, the narrowly oblong longitudinal callus mm wide apically rounded and centrally concave, 7 mm long, 0.8 mm wide. Column straight or slightly recur- vate, hemicylindric, ventrally concave, 8 mm long and 2 mm wide at the thickened apical zone. Cli- nandrium apiculate. This species is very similar to M. auyantepuien- sis, from which it differs in its inflorescences longer than the pseudobulb (vs. subequal or shorter), nar- rowly elliptic floral bracts (vs. widely elliptic), petals to 4.5 mm wide (vs. at least 6 mm in M. auyan- tepuiensis), and conspicuously narrower labellum (in M. auyantepuiensis it is approximately twice as long as wide vs. more than three times longer than wide in M. foldatsiana). Further, the labellum of M. foldatsiana is less trilobulate. As M. fol- datsiana is only known from the type collection, and the differences between the two species are not deep, we feel that more material may show M. foldatsiana to be only a variation of M. auyan- tepuiensis. However, we have studied many spec- imens of M. auyantepuiensis (alive and dried) and have never noticed intergradation in the differential characters, so we think that they are best treated as closely related but distinct species. This apparently scarce species has been col- lected only once despite repeated collecting trips to the summits of the tepuis in the last ten years. Perhaps it is endemic to Uaipantepui. We take great pleasure in naming this species after our friend and colleague Dr. Ernesto Foldats, orchidologist. He was the first to notice the new species as undescribed. Maxillaria auyantepuiensis is very common in the Gran Sabana, in southeastern Bolivar, Vene- zuela. Surprisingly, it is seldom collected. This species comprises two infraspecific taxa, one of which has remained undescribed. Maxillaria auyantepuiensis subsp. auyante- puiensis is terrestrial or lithophytic, always grow- ing on sandy soils or on acid sandstone, forming large colonies in more or less open places as scrub or savannalike tepui formations. It is usually ex- posed to full sun or resides under the light shade of shrubs. Occasionally it reaches be p iin margin or even its interior, provide light and is always over sandstone DUREE or sandy soil. Morphologically, M. auyantepuiensis subsp. auyantepuiensis is highly variable with fu- siform to (rarely) spherical pseudobulbs and sessile to long-petiolate leaves. The sheaths that conceal the pseudobulb do not defibrate but remain intact. The inflorescences vary from shorter than to longer than the pseudobulb and are always conspicuously peduncled. The flowers are held in an upright or suberect posture. The perianth segments are rel- atively long and narrow with petals 18-19 mm long, 4.3-4.5 mm wide (width/length = 0.38- 0.42) the dorsal sepal is 20-21 mm long and 3.5 mm wide (width /length = 0.16-0.17) Maxillaria auyantepuiensis Fold. subsp. epi- phytica Carnevali & I.

The subspecies are distinguished in Table 1. Both subspecies have been illustrated in Dunster- ville & Garay (1965: 181, 498). Plants A, C, and D there depict the variation to be expected in M. auyantepuiensis subsp. auyantepuiensis. Plant B represents our new M. auyantepuiensis subsp. epi- phytica. The new subspecies comprises populations of epiphytic plants from rain or cloud forest at vari- able altitudes from 600 to 1,400 m, with spherical or broadly ellipsoid pseudobulbs that are small in proportion to leaf length and are concealed by defibrating sheaths. These pseudobulbs occur on a short to long, obviously creeping rhizome, which adheres to the bark of the host tree. The leaves are always long-petiolate and very elongate with respect to pseudobulb length. The almost-epedun- culate inflorescenses are always shorter than the pseudobulbs, and the flowers are almost held hor- izontally. The flowers are of proportionately smaller dimensions than in subsp. auyantepuiensis, with relatively broader perianth segments (dorsal sepal 16-17 mm long, 4.5-5 mm wide (width/length 0.27-0.31). The labellum is almost identical in the two subspecies. Maxillaria auyantepuiensis subsp. epiphytica is superficially similar to the Ecuadorian species . neophylla Reichb. f., but this has an acute central labellum lobe. The new subspecies also sug- gests a vegetatively reduced M. desvauxiana Reichb. f. from the Amazonian Basin, but their labella are very different, and M. desvauxiana does not have defibrating sheaths concealing the pseu- dobulbs. The new subspecies has a wider distribution than the typical subspecies and extends beyond the Guayana boundaries. We know of a population in Guatopo, Estado Miranda, of the Coastal Range, represented by Patrszeck s.n., 13 Feb. 1963 (VEN), also a population from Barinitas, Estado Barinas, in the Andean foothills, from which we have living material but no voucher. The typical subspecies appears to be restricted to the acid sandy soils of the Roraima Formation, and this may explain a limited range in geographic terms even though it appears to be locally abundant in its natural habit.

BOLÍVAR: confluencia del Cano Makarupai con el Río Akaruai, unos 10-15 km al SO de la Misión de Wonken, ca. 850 m, en bosque macrotermico medio/ medio, caracterizado por una gran abundancia de epifitas debido a los rápidos de la confluencia. Floración en cultivo, Maracay, 2 Jan. 1984, G. Carnevali 1445 (VEN). This relatively scarce species has a wide range within the Venezuelan Guayana. One of the authors collected living plants of it in 1982 in the sur- roundings of Peray-tepui (W of Sta. Elena de Uai- ren, Gran Sabana, Estado Bolivar), but no voucher was made. The affinities of M. santanae lie with all the species of the Dicrypta group: M. crassi- folia Reichb. f.; M. superflua Reichb. f., and per- haps M. bicallosa (Reichb. f.) Garay, M. char- tacifolia Ames, and others. This is a difficult group in need of revision—the characters distinguishing the component members are not well defined and seem unreliable. Among the Dicrypta group, M. santanae can be easily recognized by its small vegetative stature; very narrow leaves; broadly ovate or broadly triangular, obtuse central labellum lobe; and orange-yellow or rose-lilac labellum, which has a callus in the disc and lacks another in the central lobe as is usual in other species of the group. We are pleased to name this species after Dr. Gustavo Santana, an enthusiastic orchid collector and knowledgeable amateur orchid grower. He col- lected the living plant from which the holotype specimen was prepared and kindly provided fresh vegetative and floral material for study. Maxillaria tenuis C. Schweinf., Bot. Mus.

TERRI- TORIO FEDERAL AMAZONAS: wp Pe 2 San pid de Rio Negro, on he road to Solano, 120 m, Dec. 1986, H. L. Clark 8098 (VEN). Distribution. Known from the rain forests be- tween 80 and 200 m in the Amazonian Basin of Peru, Brazil, and Venezuela. This is the first record of this species for Ven- ezuela. Since the Venezuelan material shows a few differences with the other known populations, here we offer a complete description with the full range of variation. Maxillaria tenuis seems to be rather variable. The type material from Iquitos, Amazo- nian Peru (Klug 1045, US), has sepals about three times longer than labellum (27:9.5 mm) and a triangular-ovate central labellar lobe. The second collection known, collected in Amazonian Brazil (G. A. Black 48-2676, IAN; G. A. Black 48-2747, IAN), has a very narrow central lobe (half the width of the type material) and an apparently bi- lobated labellar callus. Based on this Brazilian ma- terial, a var. amazonica Pabst was described (Pabst, 1955). All persons experienced with Maxillaria ——— & F. = herbarium material know how difficult it is to re- hydrate and reconstruct labella in these species, especially the central lobe and calluses, so we won- er if the narrower central lobe and bilobated callus are not artifacts. Provided they are not, we wou think that var. amazonica could stand as a good variety or subspecies, even though in Pabst & Dungs (1975) they seem to have rejected Pabst’s variety without explanation. The third population of the species to be sampled is the one we report here, which seems to depart from the type and from Brazilian material in having shorter sepals, less than two times longer than labellum (18: 10 mm). The labellum is identical with that of the type material. By orchid standards this seems to be a good difference for the recognition of at least a subspecies, but we feel that the evidence is too scanty, as is the known material, and further ma- terial could bridge the gap between the three known populations of this extremely variable species. Maxillaria tenuis is a well-marked species, es- pecially its vegetative morphology: oblongoid, elon- gate pseudobulbs, linear leaves, and verrucose-pus- tulose sheaths. San Carlos de Rio Negro is only a undred meters away from Colombia, across the Río Negro, so we would expect to find M. tenuis also in Colombia. LITERATURE CITED DUNSTERVILLE, G. C. K. & L.

ABSTRACT A taxonomic revision of four species of the genus Mimosa L. from A as a species, and its affinity and taxonomic position are discu iven. Mimosa petraea Chodat (Burk.) Fortun., stat. nov. is proposed of | ans ich. and M. niederleinii Burk. are is presented. Mimosa dar ae ssed. Synony et Hassl. is restricted to s Paraguayan territory. All these taxa are briefly described and their geographic distributions are given Como parte de la revisión que se esta realizando del genero Mimosa L. para la Argentina, Bolivia, Paraguay, y Uruguay, se da a conocer el estudio taxonómico de cuatro especies presentes en el área. Estas especies pertenecen a la sección Mimosa (Bentham, 1842, 1875) por presentar flores ha- plostémonas. Dentro de dicha sección, segün ciertos carac- teres exomorfológicos (hábito, presencia de acú- leos, nümero de pinnas, nümero de foliolos) se agruparia a M. pauperioides y M. balansae en la serie Pectinatae Benth. y a M. niederleinii y M. petraea en la serie Pedunculosae Benth. En el sistema de clasificacion de Bentham, la ubicación taxonómica de muchas de las especies de Mimosa en cada serie es dudosa. A través del estudio biosistemático que se esta efectuando en el género para Austroamerica se espera poder se- leccionar los caracteres de valor taxonómico. mi . Mimosa pauperiodes (Burk.)

En el material estudiado se observó que ademas de los caracteres citados por Burkart, también se podia diferenciar a M. balansae var. balansae por poseer inflorescencias mayores que las hojas, y tallos inermes o con l- 2 acüleos internodales y/o infraestipulares. Todas estas diferencias se mantienen constantes, e inclu- sive son más importantes que las existentes entre M. balansae y otras especies afines. Por lo aqui descrito, se propone considerar a M. pauperioides como especie independiente de M. balansae. En los ejemplares inermes es facil confundir a M. pauperioides con M. petraea. Ambas presen- tan afinidad en el tipo de hábito y nümero y forma de los foliolos; no obstante se diferencian por el largo del pedünculo, pubescencia, y tamano de los foliolos. Segün Bentham (1842, 1875), la serie Pecti- natae Benth. se caracteriza por agrupar sufrütices pequenos o raro arbustos, generalmente con acü- leos infraestipulares o internodales, pinna uniyu- gada, foliolos multiyugados (a veces hasta 6-8- yugados) pedúnculos 1(2) axilares o formando racimos compuestos apicales (desarrollo posterior de las hojas), racimos globosos, flores 4-meras, y craspedio setoso a hispido. A su vez, la serie Pe- dunculosae Benth. se diferencia de Pectinatae casi ünicamente por incluir especies inermes. En e estudio de ambos grupos supraespecificos, se ha observado que la presencia de acüleos es un ca- racter variable en muchas especies del género, como ocurre con M. pauperioides. Este taxon solo presenta algunas ramas con uno o dos acüleos pequenos, y a veces es una planta totalmente iner- me. Si se siguiera el criterio de Bentham, erró- Pedunculosae. Por otro lado, esta especie es más afin a M. petraea de la serie Pedunculosae. Como se ha senalado, en su mayoria, los caracteres di- ferenciales descriptos por Bentham para las series del género Mimosa no responden a un patrón estable. 2. Mimosa balansae M. Mich., Mém. Soc.

En 1947, Burkart describió para Rio Grande do Sul a M. niederleinii var. riograndensis; pos- teriormente, en 1979 la citó para el Estado de Santa Catarina. Segün él, esta variedad se dife- renciaba por presentar foliolos pubérulos en la cara abaxial y pinnas 24—54-yugadas, mientras que la var. niederleinii se caracterizaba por poseer folio- los con la cara abaxial pubérula y estrigosa y pinnas 384 Annals of the Missouri Botanical Garden 19-32-yugadas. El material tipo consultado de M. niederleinii var. riograndensis posee la mayoria de los foliolos con pubescencia pubérula, pero, tam- bién, se pueden observar algunos pelos estrigosos mezclados, como ocurre en la variedad tipica. Con respecto al nümero de foliolos por pinna, es con- veniente senalar, que el material tipo de M. nie- derleinii es un ejemplar pobre y las pinnas no poseen completos los pares do foliolos. Por otro lado, en el material brasileno, se han observado varios ejemplares con pinnas 30-50-yugadas pero con pubescencia pubérula y estrigosa en la cara abaxial de los foliolos. Ante la variabilidad obser- vada en los ünicos caracteres diferenciales, se pro- pone en esta nota considerar en la sinonimia de M. niederleinii a la var. riograndensis. ta de M. niederleinii para la Argentina fue realizada sobre la base del ejemplar tipo coleccio- nado en Varana (?), Misiones, por Niederlein en la expedición de la Comision Nacional de Limites. En 1948, Burkart senala que dicha localidad per- tenece a la parte centro-oriental de la provincia de Misiones, en la region de Fracrán. A pesar de la especificación posterior, desde 1887 hasta el mo- mento, no se ha encontrado nuevamente material de esta especie en la Argentina, en cambio si es común hallar ejemplares recientemente coleccio- nados en el SE brasileno; existe la posibilidad que el material citado fuera coleccionado en el estado de Rio Grande do Sul y no en el territorio argentino. Esta especie posee una variedad en el Edo. de Santa Catarina, Brasil: M. niederleinii var. pseu- dolepidota Burk. Esta variedad presenta tallos, peciolos, pedünculos, y craspedio con pubescencia densa, estrigosa o setulosa, y ramificada. 4. Mimosa petraea Chodat et Hassl., Bull. Herb. Boissier ser.

Jorgensen 325, IX-1909 (BAB 34712)". En el material estudiado solo se pudo encontrar un ejemplar de herbario que si bien posee los mismos datos citados en la exsiccata por Bur- kart, no coincide en la fecha de colección. En la etiqueta del material se lee XI- 1909 y no IX-1909. Esta diferencia probablemente se deba a un error de impresión. Por otro lado, el ejemplar Jorgensen 325 (BAB 34712) no pertenece a M. petraea, sino a una forma más pequeña y pubescente de oligophylla M. Mich. Al revisar todo el material depositado en el herbario del Depto. de Botánica Agricola, INTA, Castelar (BAB), se pudo compro- bar que existen más ejemplares de P. Jorgensen 325, los cuales corresponden a distintos nümeros de BAB y a diferentes especies de Mimosa, por ej.. BAB 30213, 30214, 30224 = M. oligophyl- la; BAB 32116, 32117, 32118 = M. paupera Benth., etc. A pesar de la mezcla existente entre el material y el número de BAB, ninguno de los s cita de Burkart (1948), hasta el momento no se ha encontrado esta especie en la Argentina, por lo que se cirscunscribe su distribución geográ- fica al territorio paraguayo. No se descarta que en Volume 76, Number 2 Fortunato Mimosa el futuro pueda ser coleccionada en las provincias l En el material examinado de M. petraea (Bur- kart, 1948), fue citado otro ejemplar: “Paraguay, P. Jorgensen 4450,” el cual tampoco corresponde a la variedad tipica, sino a M. petraea var. hirtula Burk. Dicho ejemplar, al igual que el tipo y demás especimenes estudiados de var. hirtula se diferen- cian de var. petraea por ser un sufrütice erecto a procumbente en la base con pinnas 1-6.5 cm long., y generalmente inflorescencias mayores a iguales que las hojas.

THE GRACILIFLORA GROUP Shrub or sometimes small tree; young stems glabrous or sometimes ferrugineous-pubescent; stipules sheathing or not, triangular or ovate or lanceolate, the apex often bifid or biaristate (Fig. 2f), uniform in color, glabrous or less commonly fringed or ferrugineous-puberulent, caducous. Leaf blades usually elliptic, sometimes narrowly so, or oblanceolate or slightly obovate, drying reddish or greenish gray, brown, or black; secondary veins 3-14(-16) pairs, diverging (45?-)55?- 90(-100%), eucamptodromous or brochidodro- mous, with collector vein only in P. jimenezii, the axils with domatia (Fig. 4b) or not (with tufts of hair only occasionally in P. bakeri); tertiary veins orthogonal reticulate (sometimes percurrent in P. marginata). Inflorescences panicles of cymes or rarely (P. bakeri and sometimes P. parvifolia) of glomerules, usually pedunculate; secondary axes usually in 1 pair per rank, if more than 1 pair then size-differentiated, often delicate or diffuse in structure and diverging at right angles (Fig. 7h); bracts rarely conspicuously enlarged (to 6 mm long in P. jimenezii). Corolla tubes (1.5-)2-4(-5) mm long (Fig. 8), the lobes usually without apical ex- tensions (sometimes with blunt protuberances in P. graciliflora). Fruit when dry usually ellipsoid to spherical (obloid in P. philacra); persistent calyx a beak or not evident; seed dorsal surface with 3-5 (6-8 in P. parvifolia) usually deep longi- tudinal furrows (Fig. 10d), the ventral surface with 2 deep or broad longitudinal furrows (plus several irregular furrows in both surfaces in P. philacra; ventral surface often concave in P. graciliflora [ Fig. 10c The most commonly encountered species in the group, Psychotria marginata (distribution, Fig. 20), does not obviously closely resemble any other species. Psychotria graciliflora (Fig. 21), the oth- er widespread species, is the centerpiece of the morphologically cohesive P. graciliflora complex, which includes also P. bakeri (Los Santos, Pana- ma), P. laselvensis (Costa Rica), P. liesneri (east- ern Panamá Province), P. orosiana (Costa Rica and Panama), P. parvifolia (Costa Rica and west- ern Panama), and P. philacra (eastern Darién Province; see Fig. 22). Psychotria jimenezii, a Costa Rican species (Fig. 23), is unique in the group in having a collector vein, inflorescence bracts as long as 4-6 mm, and seed dorsal surface with usually only three longitudinal furrows, but it too may belong to the P. graciliflora complex. Of the nine species in the group, six appear distylous. All six show between-morph asymmetry in floral part lengths: Psychotria graciliflora, P. jimenezii, P. laselvensis, P. marginata, and P. parvifolia have longer-exserted parts in pins than in thrums, and in P. orosiana pin reproductive organs are longer at both levels. The only positively derived state is seen in P. liesneri, which is long- homostylous. Available flowering material of P. bakeri and P. philacra is insufficient to determine their breeding systems. 17. Psychotria bakeri Dwyer, Ann. Missouri Bot. Gard. 67: 347. 1980. TYPE: Panama.

Leaves in Honduras and Nicaragua are at the upper end of the spectrum in terms of size and number of secondary veins, whereas Costa Rican specimens generally have the smallest leaves with the fewest secondaries. Calyx lobes are generally barely evi- dent to triangular, but in Darién and eastern Pana- má provinces the lobes are linear. The exserted style in the pin morph is noticeably longer than the exserted stamens in the thrum (4— 5 vs. 2.5-3 mm). 19. Psychotria jimenezii Standley, J. Wash. Acad. Sci. 15: 288. 1925.

Psychotria laselvensis may be recognized by its resemblance to P. graciliflora and P. orosiana and its generally larger inflorescences and leaves. It differs from P. orosiana in having leaf blades Volume 76, Number 2 1989 Hamilton 393 Mesoamerican Psychotria, Part II to 13(-16) cm (vs. 10.5 cm) long, more secondary veins (usually 10-13 vs. 7-9), inflorescence sec- ondary axes commonly 4 (vs. 2) in the first rank, and usually shorter corolla tubes (2.5-3 vs. 2.5- 5 mm). These three closely related species— P. graciliflora, P. orosiana, and P. laselvensis— form a continuum with regard to many quantitative characters, but their recognition as species is straightforward. The exserted pistil in the pin morph is conspic- uously longer than the exserted stamens in the thrum (5-5.5 vs. 3.5-4 mm). 21. Psychotria liesneri Dwyer, Ann. Missouri Bot. Gard. 67: 387. 1980.

Psychotria parvifolia may be recognized by its small (usually 1.5-5.2 x 0.8-2 cm) membranous leaves with 3-5 inconspicuous secondary veins, minute (usually 0.4-1.2 cm long) inflorescences, and spherical fruits 4-5 mm in diameter. Collec- tions from Chiriqui, Panama, show more slender inflorescence axes, longer (3 mm) pedicels plus longer corolla tubes and filaments and styles than from Costa Rica. The exserted pistil in the pin morph is usually longer than the exserted stamens in the thrum (5 vs. 3.8-5.3 mm) 25. Psychotria philacra Dwyer, Ann. Missouri Bot. Gard. 67: 412. 1980. TYPE: Panama.

Distribution (Fig. 22). Known only from the type collection from Cerro Tacarcuna, eastern Da- rien, Panama, at 1,250- 1,450 m elevation in low montane rainforest with equatorial-mountainous climate. It was collected in fruit on January 26. Psychotria philacra may be recognized by its small elliptic (5-7 x 1.7-2.7 cm) leaves drying dull red-brown and with 6-7 secondary veins, ob- loid fruits, and seeds with shallow irregular furrows on both surfaces. GROUP 4. THE REMOT4 GROUP The description for the group in Mesoamerica is that of the lone species, Psychotria remota. Key recognition characters include leaves drying glossy red-brown and relatively few secondary veins for the large size of the blade. This group is larger in South America, including also P. anceps Kunth and P. cupularis (Muell. Arg.) Standl. Psychotria remota appears normally distylous, with no floral-part-length asymmetry between the morphs. 26. Psychotria remota Bentham, J. Bot. (Hooker) 3: 225. 1841. Mapouria remota (Benth.) Muell.

The inclusion of P. alboviridula within P. re- mota is discussed by Steyermark (1972; Mem. New York Bot. Gard. 23: 477) Psychotria remota may be recognized by its moderately large (usually 11-24 cm long) elliptic leaves drying glossy red-brown, few (usually 8-12) secondary veins generally with prominent domatia in the axils, reduced (except for the first rank) and winged secondary inflorescence axes, and large (usually 7-9 mm long) ellipsoidal fruit. GROUP 5. THE NERVOSA GROUP Shrub; young stems glabrous or red-brown to brown tomentose to puberulent; stipules usually sheathing, linear (Fig. 2c) or ovate, the apex some- times bilobed or paene uniform in color (except P. fosteri, with a darker red-brown midrib), gla- brous or fringed or red- brown pubescent, caducous. Leaf blades obovate or elliptic or oblanceolate, drying red-brown to green-brown (often chalky yel- low-green in P. fruticetorum), sometimes pale be- low; secondary veins (4-)5-17 pairs, diverging 35°-65° (except 70?-80? in P. fosteri), eucamp- todromous or brochidodromous (with collector vein in P. chagrensis and P. fosteri), the axils usually with tufts of hairs (lacking in P. chagrensis, P. fosteri, and usually P. nervosa); tertiary veins re- ticulate or percurrent. Inflorescences panicles of cymes (often contracted in P. nervosa) or fascicles of flowers (in P. chagrensis and P. fosteri), not pedunculate (except P. erythrocarpa, P. fruti- cetorum, and often P. jinotegensis); secondary axes usually in 1 pair or less commonly 2 size- differentiated pairs per rank (4 equal axes per rank rarely in P. nervosa); bracts conspicuously en- larged in P. chagrensis, P. fosteri, and P. fruti- cetorum. Corolla tubes 2-4 mm long (6-7 mm in P. chagrensis), the lobes without apical extensions. Fruit ellipsoid when dry (narrow in P. nervosa); persistent calyx a tube to 5 mm long (Fig. 9d) 400 Annals o Missouri Botanical Garden or a beak or inconspicuous; seed dorsal surface with 4-5 deep longitudinal furrows (or 6-8- many irregular furrows in P. aguilarii and P. Jinotegensis), the ventral surface with 2 deep or shallow longitudinal furrows, sometimes incom pletely divided in P. nervosa or with additional irregular furrows in P. jinotegensis. Of the nine species, three fairly widespread ones do not closely resemble any others: Psychotria fruticetorum, with its biaristate stipules, leaves drying chalky yellow-green, pedunculate inflores- cences, and bracts as long as 8 mm; P. erythro- carpa, with its linear stipules and pedunculate inflorescences often of glomerules; and P. jinote- gensis, with its often pedunculate inflorescences and many irregular furrows on both seed surfaces. The P. chagrensis complex shares a collector vein, an absence of tufts of hairs in the axils of the secondary veins, and inflorescences of fascicles of flowers and with bracts conspicuously enlarged; the complex comprises the widespread P. chagrensis and P. fosteri, endemic to Coiba Island, Panama (Fig. 26). The P. nervosa complex includes that widespread species plus P. aguilarii (southern Guatemala), P. boquetensis (western Panama), and P. mirandae (southern Mexico); none of them de- viates morphologically from the predominant char- acter states of the group Of the nine species in the group, seven appear distylous. Of those, Psychotria fruticetorum has onger exserted parts in the pins than in thrums, and P. chagrensis has longer inserted parts in the pins. One species, P. mirandae, appears to be thrum-monomorphic. Only P. fosteri may not be evaluated for this character due to lack of adequate flowering material. 27.

Lorence, pers. comm.), so P. chamissoana, defined by its glabrous aspect, is included within P. ery- throcarpa. Psychotria erythrocarpa may be recognized by its usually pale brown to red-brown tomentose as- pect, obovate leaves with few (usually 6-8) sec- ondary veins diverging acutely (35?—50*), and small (usually 2.5-5.5 cm long) inflorescences with sec- ondary axes two per rank in three ranks. The fruits occupy the small end of the spectrum in Veracruz and the large end in Chiapas and southward. 31. debo fosteri C. Hamilton, Phytologia 64: 1988.

Psychotria fruticetorum may be recognized by its small leaves (usually 5-7 x 2-4 cm) drying chalky yellow-green to red-brown with barely el- evated secondary veins and inconspicuous tertia- ries, its small inflorescences (1.5-4.5 cm long) with secondary axes usually 2 per rank in 3-4 ranks, and small (4-5 x 3-3.5 mm) ellipsoid fruit. Mex- ican collections differ from those from the rest of the range in having generally smaller leaves, 5 vs. 6-7(8) secondary veins, and a higher fruit length- to-diameter ratio. The exserted pistil of the pin morph is often longer than the exserted stamens of the thrum (3.5-5 vs. 3.5-4 m 33. Psychotria jinotegensis Nelson, Molina & Standley, Phytologia 50: 1. 1981.

All the species in synonymy have been properly synonymized before, with the exception of P. quiinifolia, the morphology of which does not differ from that of P. nervosa. Degree of pubescence varies within populations, and infraspecific taxon- omy based on this character (e.g., subsp. rufescens) is not recognized. Psychotria nervosa may be recognized by its usually reddish pubescent aspect, leaves with usu- ally eucamptodromous secondary veins diverging 55?-65^, small (1-4(-5) cm long) inflorescences lacking peduncles and with secondary axes usually 2 per rank in usually 3 ranks, and narrow-ellip- soidal fruit (5.5-7 x 2.5-3 mm). There appears to be no geographic component to the variation between glabrous and densely tomentose aspect. Collections from Florida are noteworthy for small eaves and relatively large inflorescences. GROUP 6. THE PANAMENSIS GROUP Shrub or tree; young stems glabrous or (often red-brown) puberulent; stipules usually sheathing, lanceolate (Fig. 2d) or ovate, or less commonly linear or triangular with the apex sometimes bilobed or biacuminate, uniform in color, glabrous or fringed or puberulent, caducous. Leaf blades usually ellip- tic, or sometimes obovate, ovate, or lanceolate, drying green-brown to red-brown to brown, some times paler below; secondary veins (4—)6- 19(- 22) pairs, diverging (30?-)45?—75*(-809), eucampto- dromous to brochidodromous, the axils sometimes with domatia (sometimes P. cocosensis and P. lun- dellii) or with tufts of hair (sometimes P. chiri- quina, P. lundellii, and P. mexiae) or usually lacking; tertiary veins orthogonal reticulate to per- current. /nflorescences panicles of cymes (or of glomerules sometimes in P. panamensis or of in- dividual flowers in P. hornitensis), nonpeduncu- late (Fig. 7e) except in P. olgae, P. stockwellii, and sometimes in P. cascajalensis, P. chiriquina, P. dwyeri, P. lundellii, P. panamensis, P. sara- piquensis, and P. trichotoma; secondary axes usually in 1 pair per rank or less commonly 2 equal pairs or 2 size-differentiated pairs per rank, diverging acutely except in P. stockwellii; bracts not conspicuously enlarged, to 3 mm long only in P. chiriquina. Corolla tubes (1.5-)2-5 mm long, the lobes without apical extensions. Fruit ellipsoid, obovoid, or spherical when dry; persistent calyx a beak or less commonly a conspicuous tube (P. cocosensis [Fig. 9c] and P. olgae and sometimes P. panamensis) or often not evident; seed dorsal surface with (3—) 4—10 often irregular longitu- dinal furrows, the ventral surface with 2 deep plus often several irregular longitudinal furrows (Figs. 10g, 10h) Half of the 12 species of the group are assigned to the Psychotria panamensis complex; P. pana- Volume 76, Number 2 1989 Hamilton 413 Mesoamerican Psychotria, Part II 300 km 105 100 95 ‘= L e A ee A « 9. 90 ^ 85 80 L i L E 28.

Three other widespread species have character states that distinguish them from typical members of the group and are of uncertain affinities, although analysis might reveal they belong in the panamensis com- plex: P. trichotoma has obovoid fruits and con- spicuously brochidodromous venation; P. sarapi- quensis has usually narrowly oblanceolate leaves; and P. mexiae has 5-8 deep irregular furrows on the seed dorsal surface. The most cohesive complex is that of P. chiriquina, which includes that species (Nicaragua through Panama; Fig. 29), P. lundellii (Chiapas through El Salvador; Fig. 29), and P. hornitensis (western Panama; Fig. 30); they share ovate stipules and shallow furrows on the see ventral surface. Of the 15 taxa in the group, eight appear di- stylous; of those, Psychotria dwyeri, P. mexiae, olgae, P. stockwellii, and P. trichotoma show some between-morph asymmetry in floral part lengths. Psychotria lundellii appears to be pin- monomorphic in Belize, but recently I examined a thrum collection from Guatemala.

Psychotria hornitensis may be recognized readily by its small, narrow (2.5-3.5 x 0.5-0.7 cm) leaves and small (2.5-3 cm long) few-flowered inflorescences. The one flower morph found does not show significant differentiation in length between the exserted style and stamens, so the species is pre- sumed to be long-homostylous. 41.

Psy- chotria lundellii differs from the similar P. chi- riquina in having smaller (5-6 vs. 8-10 mm long) stipules, brochidodromous (vs. eucamptodromous) secondary venation, shorter (2-2.5 vs. 4-6 mm corolla tubes, and spherical (vs. ellipsoid) fruits. Material from El Salvador shows generally more secondary veins in the leaves than material gath- ered elsewhere. Eight flowering specimens from Belize have been examined, and only the long-style morph has been found, suggesting that the short-style morph has been lost in populations in that country.

The existing name Psychotria nigrescens De Wild. (dating to 1924) leaves ““mex- iae" as the oldest available epithet. Psychotria mexiae may be recognized by its elliptic long-acuminate leaves drying green-brown to red-brown with veins drying reddish below; glo- bose panicles without peduncle and with 4 equal secondary axes in each of the first 2 ranks; long (2.5-4.5 mm) corolla tube often drying pink; and ellipsoid to spherical fruit drying often shiny red- brown and appearing smooth outside due to the irregularity of the furrows on the dorsal surface of the seed. Corolla tubes are shorter in specimens from Belize (2.5 mm) than in those from Mexico (4-4.5 mm), and the stamens and styles are scaled down accordingly. Fruits are larger (5-6 mm long) in specimens from Veracruz and Guatemala than from elsewhere (4.5-5 mm long). The exserted pistil of the pin morph is usually longer than the exserted stamens of the thrum (4— 7 vs. 3.5-5.5 mm). 43. Psychotria olgae Dwyer & Hayden, Ann. Missouri Bot.

The morphologies of P. grandistipula Standl., P. yunckeri, P. molinae, and P. durilancifolia fall well within the broad range of P. panamensis var. panamensis, so these former species are esed with var. panamensis. Psychotria panamensis var. panamensis shows great variation within its range, including the fol- lowing: leaves from Veraguas, Panama, are nar- rower and more coriaceous than those from else- where; leaves from Colón, Panama, are unusually large; secondary veins are more numerous in ma- terial from Guatemala, Honduras, and Colón and fewer in material from Chiapas, Mexico, and from Coclé, Panamá, and Veraguas provinces in Pan- ama; secondary vein angle of divergence is greatest in leaves from Chiriqui, Panama; secondary veins are brochidodromous in Nicaraguan specimens; in- florescences are largest in specimens from Panama and Costa Rica; flowers are generally larger in Costa Rican material; and the corolla tubes from Honduras are narrowest (1.5 mm) 45.

Psychotria sarapiquensis may be recognized by its usually narrow (length/width — 3) leaves with few (6-9[-11 ]) secondary veins and its large (7-8 mm long) ellipsoid to often obovoid fruit drying black or dark red-brown. Mexican material is noteworthy for having lan- ceolate leaves with secondary veins diverging 60?- 70°. Collections from the Fortuna and El Valle areas in Panama have large (to 18 cm long) broadly elliptic leaves with ca. 11 secondary veins, but they fit this species concept in other respects. Three of the Costa Rican collections— Dryer 1539 (not cited above), Skutch 3282, and Haber 53 1 —have subcoriaceous leaves drying red-brown and pedun- culate inflorescences. Psychotria sarapiquensis is the most variable and/or the most problematic species in this treatment; it is conceivable that additional material from throughout its range will reveal it to be two or perhaps three different taxa. 46.

Psychotria stockwellii may be recognized readily by its inflorescence, whose secondary axes diverge over 90? from the main axis and whose tertiary axes diverge likewise from the secondary axes, and so forth, a character state unique in the subgenus. In addition, P. stockwellii differs from P. pana- mensis in having a larger corolla tube (4-5 vs. 2- 3 mm long), long-pedunculate inflorescences, and conspicuous to evident (vs. inconspicuous) tertiary veins. Reproductive organs at both levels are longer in the pin morph than in the thrum. 47. Psychotria trichotoma M. Martens & Me e e Acad. Roy. Sci. Bruxelles 11: 221 4. Uragoga trichotoma (M.

NEW SPECIES AND OTHER TAXONOMIC MATTERS IN THE NEW WORLD MEMECYLEAE (MELASTOMATACEAE) Thomas Morley! ABSTRACT r new species of Mouriri and one of (dial are described and illustrated. Mouriri beider is a to Fou a variety of / - gleasoniana. The relation of Votom seed structure; no change drawings of M. longifolia and V. pubescens are provide to Mouriri is discussed in the light of new on in generic boundaries is inibi ah for the present. Supplementary dl jur: d. Recent collections and older ones recently iden- tified correctly to genus have yielded five new species of the tribe Memecyleae DC. (Melastomataceae). Four of these are members of the genus Mouriri: one from the Osa Peninsula of Costa Rica, one from western Venezuela in the state of Táchira, a third from southern Venezuela in Amazonas, and the fourth from northeastern Peru and adjacent Brazil. Also in Mouriri, new collections of M. glea- soniana from the Panama mainland, from Costa Rica, and from the island of Coiba revealed much intraspecific variation and require reassessment of the status of its close ally, M. coibensis. A recent flowering collection of M. longifolia permits the completion of its description and illustrations and allows its sectional placement. The fifth new species is a Votomita from Roraima of Brazil, the eighth known member of that small genus. The specimens of this species, as well as those of another collection of V. pubescens, bear ripe fruit, so that it is now possible to compare more accurately the seeds of Votomita and Mouriri. Previously, mature seeds were known only from V. monantha of Cuba. A discussion of ovule and seed structure and of ge- neric relations therefore follows the description of V. roraimensis. More collections of V. pubescens make possible the completion of the descriptions and illustrations for that species. References in the descriptions to the "type" of stomatal crypt refer to the forms described on pages 6 and 7 of Morley (1976). Mouriri osaensis Morley, sp. nov. TYPE: Costa ica.

Distribution. Known only from the type lo- cality in the western part of the Osa Peninsula on the southwest coast of Costa Rica. The new species appears to belong in subg. Mouriri sect. Olisbea. The characteristics sug- gesting this alignment are the large leaves, absence 432 Annals of the Missouri Botanical Garden of stomatal crypts, simple upper epidermis with mucilaginous walls, stellate terminal sclereids, and lack of a hypodermis. Within the section, the new species is closest to M. completens, on the basis of the former's similar leaves with a cordate ten- dency, very similar upper epidermis and foliar sclereids, and above all, the circumscissile hypan- thium as seen on the fruit. The absence of flower characters of course detracts from understanding the relationships, but I still regard this alignment as reasonably certain. Mouriri osaensis differs from M. completens in leaf, fruit, and seed characters. The leaf blade is less cordate than in M. comple- tens; the fruit is purple instead of greenish, lacks a broad stipe at base, and is not abruptly narrowed to the hypanthium at the apex, nor is it lobed according to the seed number; the hypanthium on the fruit is 7-11 mm in diameter rather than 4.5- 7 as in M. completens and is only 1.5-2 mm deep instead of 3.8-4.5 mm. The seeds are a bit smaller and differ in shape, best compared in the illustra- tions. Mouriri papillosa Morley, sp. nov. TYPE: Ven- ezuela.

Section Mouriri contains three species i in ad- panthium, anthers, thecae, and splitting distance 434 Annals of the Missouri Botanical Garden between calyx lobes. It further differs from M. barinensis in having short petioles. The curious multiple lamellations in the mucilage walls of M. papillosa I have noted elsewhere only in two collections of M. barinensis. Since this char- acter varies in the latter species, it is possible that it will also prove to be a variable in M. papillosa. Although plants of sect. Litophyllum lack a hypodermis, in other respects some of them re- semble rather closely the members of sect. Mouriri. Most similar is M. gleasoniana, including its var. coibensis. From this, M. papillosa differs in its lack of a two-winged lower midrib and in its pa- pillose ovary and longer ovary plus calyx, longer anthers and thecae, and greater splitting distance between the calyx lobes.

Known only from the type lo- cality in tropical rainforest near the west-central border of Amazonas, Venezuela, between the head- waters of the Guainía and Atabapo rivers. Mouriri latihila clearly falls within subg. Mou- riri on the basis of its tubular midrib xylem and its seed with a large polished area. The new species is very distinctive, standing apart on the combi- nation of its tetramery, closed calyx, and small Type II stomatal crypts. Its sectional relation is uncertain; it is here placed tentatively in sect. Litophyllum because of its tubular midrib xylem, small crypts, leaf shape, small flower, and lack of a hypodermis (Morley, 1976: 36). When placed here, it weakens further the already weak sectional boundaries. From this position the new species ap- pears to have ties with sect. Megacrypta, whose two species also have tetramery, closed calyces, and columnar sclereids. The new plant differs widely from these two, however, in its much smaller leaves and small Type II stomatal crypts, as well as in its shorter pedicels and calyces. Within sect. Lito- phyllum, no species appear very similar to M. latihila, although two are tetramerous and have short one-flowered peduncles like the new species: M. exadenia and M. lancifolia. Mouriri latihila differs from M. exadenia in having Type II crypts, columnar sclereids, a closed calyx, and a different seed shape; from M. lancifolia it differs in its broader leaves, presence of stomatal crypts, co- lumnar sclereids, and closed calyx.

Mouriri, its tubular midrib xylem, anatropous ovules, and polished seed being the determining features. The tetramery, monoporous and eglan- dular anthers, and persistent petals of this entity make it very distinctive. This is only the second species of the genus to be found with monoporous anthers, and persistent petals have not been noted before. The petals were persistent on the green but nearly ripe fruits of the type collection; they were gone from the ripe fruit of the paratype. It is impossible to know if they had dropped naturally or were broken off during collection in the latter case. Within its subgenus the new species is most similar to three species in sect. Litophyllum: M. exadenia, M. latihila, and M. monopora. Prob- ably M. retentipetala is most closely related to these three and belongs with them in sect. Lito- phyllum The chararieriiiks of M. retentipetala sug- gesting the three species named are: small simple stomatal crypts, a one-layered upper epidermis, small flowers, tetramery, monoporous eglandular anthers, a one-locular ovary with few ovules, and a large hilum on the seed. Some of these characters are not found in all three of the presumed allies, and several have not yet been investigated in M. latihila owing to lack of material. Mouriri retentipetala differs from M. exadenia in having higher, more numerous stomatal crypts, pedicellate flowers, persistent petals, monoporous caudate anthers, and a large hilum on the s From M. monopora the new species departs in its tetramery, triangular calyx lobes, and eglandular anthers with a longer cauda and straight thecae. From M. latihila, M. retentipetala varies in hav- ing stellate foliar sclereids, short calyx lobes so that the petals protrude from the calyx early in the bud, and persistent petals. Mouriri gleasoniana Standley ex Standley & Steyermark var. coibensis (Morley) Morley. Mouriri coibensis Morley, Fl. Neotropica 15: 143-145. 1976 Recent collections of M. gleasoniana from Cos- ta Rica and Panama require reassessment of the status of M. coibensis, a close relative of the former species from the island of Coiba off the southwest coast of Panama. When M. coibensis was de- scribed, M. gleasoniana was known only from Honduras to Mexico, and the differences between the two taxa as then known were sharp. The new material partly bridges the gap between them and seriously weakens their separation. I believe real- ities are best served viewing both as part of a single variable species. As presently known, the island plants are sl pasan and are re- tained as a variety. Six major variables are in- volved, as shown in Table 1. Plants of the complex are yet to be found in Nicaragua. 438 Annals of the Missouri Botanical Garden TABLE 1. Geographic variation in six characters of Mouriri gleasoniana.

In the one flowering collection from Panama (Knapp & Huft 4424) and one of the two Costa Rican collections (Hammel 9317), the large number of ovules ap- parently results in an unusual placentation in that the ovules in each locule are arranged on all sides of the axile- ine placenta. These are the only nown pl such an arrangement in sections 4 dur. 9 of subg. Mouriri. A transition from a large number of ovules to a small one raises the question of which state, if either, represents the primitive condition. A similar trend was found in M. guianensis, where the con- clusion was that the greater number was primitive (Morley, 1983). In M. gleasoniana the presence of the larger numbers close to South America, where the genus appears to have originated, with the smaller numbers to the north, where the en- vironment gradually becomes more extreme, sug- gests that the same interpretation should be made in this species. Throughout the range, the fruits are 1-4(-5)-seeded; as in M. guianensis, many ovules must therefore abort when a large number is present before fertilization. Accordingly, those plants with fewer ovules in the flower and thus less wastage would be regarded as better adapted and, in this case, more specialized. It would appear that in increasingly extreme environments the demand or floral economy becomes greater. Mouriri longifolia (HBK) Morley. Until re- cently, this species was known only from fruit- ing material. A flowering collection has now been made, so that the following addendum to the description of the species can be given, with illustrations (Fig. 5).

Petals ovate-oblong, ca. 10 mm long in- cluding a basal claw ca. 3 mm long, 7 mm wide, broadly acute at apex, erose toward the base. Fil- aments 11-14 mm long; anthers 3-3.3 mm long; thecae 2.8-3 mm long, dehiscing by apical slits; gland 0.8-1 mm long, 2.1-2.3 mm from apex of anther when measured from center of gland; cauda 0.6-0.8 mm long. Ovary 5-locular; placentae basal in each locule, the ovules borne on all sides of a short basal column, ca. 5 per placenta, ca. 25 in all; style 17-22 mm long. With the flowering material in hand it now be- comes apparent that M. longifolia belongs in sect. Apirangia. Specifically, the characters that place it there are the tubular midrib xylem, filiform scler- eids, Type III crypts like those of M. apiranga, the lack of a hypodermis, the free calyx lobes with the petals protruding from them early in the bud, the anther shape which generally agrees with that of the other species, the proximate position of the placentae which are not widely separated, and the position of the ovules on all sides of each placenta.

It is allied to the other four species that have four locules or placentas, numerous ovules, and (with one ex- ception) hairs on the midrib. Its laterally fused stamens occur in two members of this group of four, V. plerocarpa and V. monadelpha. From all of these the new species differs in having much smaller leaves and flowers and only 15-16 ovules. Three of the other four, V. monadelpha, V. or- binaxia, and V. plerocarpa, have 36-48 ovules. The fourth, V. pubescens, is closest in ovule num- ber with 20-26, but the new species differs greatly from that species by having small nearly glabrous leaves, a nonindurated ovary wall, laterally fused stamens, four locules, and a persistent style. The remaining three species in the genus, V. guianen- sis, V. orinocensis, and V. monantha, have one- locular ovaries with 8-10 ovules and glabrous mid- ribs. Because of its small leaves, small flowers, and geographic proximity, a close relation of V. rorai- mensis to V. orinocensis and the related Cuban species V. monantha seems likely, although the floral structure mostly does not sustain this view. The small leaves, deep hypoderm, and persistent style of the new species in particular suggest NV. monantha, although the hypoderm of the former differs in having abundant mucilage walls. Ovules in Votomita and Mouriri vary from a campylotropous type in which the ovule is bent at a sharp angle from a short, broad placental at- tachment at the chalazal end to half-anatropous, and fully anatropous forms occur in Mouriri. In V. pubescens and V. roraimensis, the ovules are half-anatropous and are borne on an axile placenta, the only known examples of such a combination in the two genera. In Mouriri, half-anatropous ovules occur only on axile-basal, free central, or asal placentas. In V. pubescens, the ovules are sessile laterally with extruded inner integuments that appear to serve as internal stigmas (Fig. 7D). Seeds are known in three species of Votomita: V. monantha, V. pubescens, and V. roraimensis. In V. monantha, which has free-central placen- tation, the angular distance on the seed between the micropyle and the broken chalazal strand is about 94°, while in V. roraimensis and V. pubes cens, with axile placentation, the angles are 60? and 50? respectively. In V. monantha the whole abaxial (outer) sur- face of the seed is smooth, whereas in V. rorai- mensis and V. pubescens the smooth part is narrow and is broadest at or near the micropylar end (Figs. 6L, 7F). In none of these seeds is the smooth part polished. Seeds of the latter two species resemble superficially seeds found in Mouriri sect. Brevi- pedillus; however, in that section the smooth area is narrowest at the micropylar end and is usually conspicuously widened at the opposite end nearest the broken chalazal strand. I have no explanation for the difference in shape. The reason for the smooth area is unknown; it may be that this is the part of the ovule first pushed against the ovary wall as enlargement begins. THE GENUS QUESTION Partial generic differences between Votomita and Mouriri in ovule and seed structure are sug- gested by the above and may be summarized thusly: (1) half-anatropous ovules on an axile placenta occur only in some species of Votomita; (2) the smooth area of the seed is unpolished in Votomita but is polished in almost all species of Mouriri; (3) in no known species of Votomita does the smooth area cover all of the seed except for the hilum, as it does in seeds of the subgenus Mouriri; and (4) seeds of Votomita most closely resembling those of Mouriri are found only in sections Acutiflos and Brevipedillus of Mouriri subg. Taphroxylon. Seeds of V. monantha somewhat resemble those of sect. Acutiflos but lack the polished face and rugose surrounding area of the seeds of that section. Seeds of V. pubescens and V. roraimensis have narrow smooth areas with surrounding rugose surfaces as in Mouriri sect. Brevipedillus, but the smooth parts differ in shape as described above. e above considerations may affect present generic divisions. The seed structure in V. rorai- mensis and V. pubescens maintains the difference between Votomita and Mouriri subg. Mouriri but increases the resemblance between Votomita an Mouriri subg. Taphroxylon. It may be that the New World Memecyleae should be regarded as consisting of three genera or subgenera: Votomita, Mouriri, and Taphrox- ylon. Absolute differences exist between all three groups, the most between Votomita and subg. Taphroxylon, the fewest between subgenera Ta- phroxylon and Mouriri, thus supporting the pres- ent disposition of these groups. Between Votomita and subg. Taphroxylon the differences are those of midrib xylem form, flower mery, hypanthium development with accompanying features of sta- men form, and the presence or absence of free stone cells in the petals. Between Votomita and subg. Mouriri the differences are the presence or absence of free stone cells in the petals, and seed structure; between subgenera Taphroxylon and Mouriri the single absolute difference is that of 442 Annals of the Missouri Botanical Garden 15 FIGURE 7.

Mouriri than subg. Taphroxylon, even though seed structure in Votomita is more like that of the latter. Because the above differences do not negate the present arrangement of genera, I think any serious effort to reconsider the generic divisions must await more evidence. Seeds of more species of Votomita should be examined, and detailed comparative stud- ies of wood anatomy, karyotypes, and phytochem- istry may be expected to aid in the evaluation. When the similarities and dissimilarities between the three are well known it can then be decided how many of them should be assigned generic status. Votomita pubescens Morley.

STUDY OF THE FLORA OF RUCAMANQUE, CAUTIN PROVINCE, CHILE: Carlos Ramirez,’ Enrique Hauenstein,’ José San Martín* and Domingo Contreras? ABSTRACT The flora of forest, scrub, and grass communities was studied in Rucamanque, located near the city of Temuco, Cautin Chile, in the central valley of south central Chile. Forty-six vegetation samples were made, an collected intensively outside the sample areas. A importance of each in the different vegetational communities, and their uses in industry, crafts, and medicine ucamanque, ““The House of the Condor" in Mapudungun, the language of the indigenous peo- ple of this region (Ramirez-Sanchez, 1985), is a valley located 12 km northwest of the city of Te- muco, capital of the IX Region of the Araucania, Chile (Fig. 1). The primitive forest vegetation of this valley escaped destruction during last century's process of colonization of central southern Chile (Donoso, 1983) because it was protected as an early watershed area for the drinking water for Temuco (Magofke, 1985). With the increase in population, water for the city had to be drawn from other sources, principally subterranean, so the state lost its interest in Ru- camanque and offered it for sale in March of 1986. Because of its value as a forest relict and its sci- entific interest, several state and private institutions and ecological organizations intervened to preserve it from exploitation. Finally, the University of the Frontera in Tem ie the legal owner, saving the relict forest for science, education, and the general public. The present catalog of the flora of Rucamanque was made during the time that the land was for sale. STUDY AREA camanque is a small river valley oriented southeast-northwest to the south of the Ñielol- Huimpil hills (Magofke et al., 1986). Through it runs Chivilcán Creek, which receives the water of two small unnamed streamlets. Its elevation ranges from 300 to 530 m. The area occupies about 525 ha, including some of the adjacent forests that belong to private owners. The basin and slopes of Rucamanque Valley are covered by native forest, which is evergreen in the lower areas and partially deciduous at higher elevations. In several places the forest has been destroyed and secondary scrub replaces it. In the higher slopes, originally of de- ciduous forest, permanent grasslands of human origin can be found. Small bogs, which we include in the grassland formation, appear in open areas on the edges of streams at the bottom of the valley. The climate of the area is humid and temperate with a Mediterranean influence (Di Castri & Hajek, 1976). The average annual rainfall is 1,400 mm and the median annual temperature is 12°C. Rain- fall is abundant in winter, and summers often have one to two dry months, as shown in the climatic diagram in Figure 1. Winter and spring frosts are frequent. To this climate corresponds a subtropical semideciduous forest type as natural vegetation (Schmithüsen, 1956). The Nielol- Huimpil hills comprise a tectonic unit characteristic of the central valley of Chile and do not connect with either the Coastal Ranges or with the Andes. The red clay soil does show similarity to the Coastal Range soils (Weinberger & Binsack, 1970). When cultivated or grazed, this soil is sub- ject to erosion. METHODS The catalog of plant species of Rucamanque was made from 46 vegetation samples taken using the E l "x Ae by Grant RS-84-22 from the Research Fund of Universidad Austral de Chile, Valdivia, and the Projecto 88. 7 of the research fund of the Universidad Católica de Chile, Sede Te emuco, * Instituto de Botánica, Universidad Austral de Chile, Casilla 567, Valdivi via, Chile. * Departamento de Ciencias Nat urales, Universidad tollen de Chile, Casilla 15-D, Temuco, Chile. * Area de Ciencia, Universidad Católica de Chile, Casilla 617, Talco, Chile.

Other plants, collected outside the study quadrats, were added to the collection. Eighteen samples were taken in the forest, 20 in scrub vegetation, 6 in pastures, and 2 in bogs. The vegetation contains the following associations: Lapagerio—Aextoxiconetum punc- tatii, Nothofago—Perseetum linguae, Fuchsio— Chusqueetum quilae, Rhaphithamno- Aristote- lietum chilensis, Chusqueetum coleu, Aristotelio— Rubetum constrictae, Hyperico-Agrostidetum castellanae, and Juncetum procerii (Oberdorfer, 1960; Ramirez, 1982; Hilldebrand, 1983). The frequency of each species was estimated in each plant association. The relative importance value was calculated adding this frequency and the average cover expressed in relative percentage of each species in the different associations according to the Wikum & Shanholtzer (1978) method. This value was not determined for species collected out- side the quadrats. Nomenclature and phytogeographic origin of the taxa were based on Marticorena & Quezada (1985) and the family nomenclature on Cronquist (1981). The common names are according to Munoz (1966). Introduced species were classified using the Ger- man flora by Rauh & Senghas (1968).

Vines, epiphytes, and parasites were included under phanerophytes. The interpretation of the biological spectrum was based on Cain (1950) Information was added on the present and po- tential uses of the plants. RESULTS AND DISCUSSION The flora of the study area is made up of 203 species, of which 190 were inventoried in the 46 vegetation samples taken in the forest, scrub, and grassland formations (Appendix I). The other 13 species were collected outside the sample quadrats. The 203 species are distributed among 161 genera, 84 families, and 6 classes (Table 1). The class with the greatest number of taxa was Magnoliopsida (dicotyledons), which include almost 69% of the species present in Rucamanque. Following these are the Liliopsida (monocotyledons) with 42 species (21%), and the Polypodiopsida (Filicinae) with 16 species (8%). The best-represented family of the Magnoliop- sida was the Asteraceae, with 18 genera and 25 species, amounting to 12% of the total. Next came the Fabaceae with 4 genera and 9 species, the Apiaceae with 6 genera and species, the Lamiaceae and Rosaceae with 5 species each, and the Myr- taceae, Proteaceae, and Scrophulariaceae with 4 446 Annals of the Missouri Botanical Garden TABLE l.

Outstanding among the Liliopsida are the Poaceae, with 16 genera and 18 species, the Cyperaceae with 5, and the Juncaceae with 4 species. Among the ferns, the Hymenophyllaceae presented 6 species, all of which were epiphytes in the forest formation. ORIGIN Of the 203 species, 147 (72.41%) are native and 56 (27.58%) are introduced (Table 2). This high percentage of introduced weeds indicates a strong human influence on the vegetation (Sukopp, 1969). The introduced species only belong to the classes Magnoliopsida and Liliopsida, and make up 31.4% and 28.6% of each group, respectively. Of course the greatest percentage of introduced species is found in the shrub grassland formations, of an- thropic and therefore secondary, origin (Ramirez, 1982). The evergreen forest of Aextoxicon punc- tatum is the association least invaded by weeds. The majority of the introduced species are origi- nally European and of little grazing value (Mon- taldo, 1975; Anazco et al., 1981). LIFE FORMS The biological spectrum of the study area was constructed from 200 species; the remaining three were mosses. In the epiphytic synusia that were not considered, mosses are very abundant (Riveros & Ramirez, 1978). The most-represented life form was the phanerophytes with 80 species, repre- senting 40% of the total. This life form abounds in forest and scrub formations, occupying different strata in the vegetation. Chamaephytes and cryp- tophytes were the scarcest, with eight species (4%) each. Hemicryptophytes appeared in about the same numbers as phanerophytes, with 78 species, or 39%. Therophytes were represented by 26 species, or 13%. The latter two herbaceous life forms were abundant in grassy and scrub formations (Table 3 The biological spectrum here described (Fig. 2) corresponds to a phanerophytic phytoclimate, typ- x ical of intermediate latitudes in temperate zones (Cain, 1950). The relative abundance of hemi- cryptophytes and therophytes is related to the de- gree of anthropic intervention suffered by the orig- inal vegetation. In the original vegetation, these ife forms certainly were not as important. This is confirmed by separating the native ele- ments from the introduced for each life form (Table 4, Fig. 3). Only one of 80 phanerophytes is exotic. The cryptophytes are all native. Among the cha- maephytes and hemicryptophytes, the percentage of introduced species is much higher, reaching 37.5% and 38.5%, respectively. Cryptophytes are not very frequent, unlike the hemicryptophytes, which contribute 30 exotic species. These perennial cespitose herbs and rosettes are plants that accom- pany man and do not characterize any particular phytoclimate (Le Blanc, 1963). Their abundance is due to destruction of forest and to grazing, which impedes their replacement by more aggressive woody species (Pessot & Montaldo, 1974). The therophytes constitute a special case of plants typical of dry climate or weeds of cultivated areas. They act as pioneers in uncovered soil (Cain, 1950). Only 15% of the therophytes present in the study area are native. This life form was scarce in the original vegetation but invaded anthropo- genic grasslands formed on eroded soils, where the vegetational cover never reaches 100%. Thus, therophytes are not typical of Rucamanque. The phanerophytes, therefore, make up the most TABLE 3. Biological spectrum of the flora of Ruca- manque.

Shrubs were very abundant, 28 species, 35% of all the phanerophytes. This life form dominates the secondary scrub and tends to invade degraded and abandoned pastures or grassy areas (Ramirez et al., 1984a, 1985). Twenty-two species of trees were present, or 27% of the total. Sixteen climbing plants flourish in Rucamanque, making up 20% of the total. The most robust of these, Hydrangea serratifolia, can have a stem diameter of up to 15 cm.

The epiphytes, principally filmy ferns of the Hymenophyllaceae, presented 11 species, or 13.5%. Only three parasitic species were present. FREQUENCY IN THE PLANT ASSOCIATION Only two species were present in each of the eight studied plant associations: Rubus constrictus and Prunella vulgaris (Table 6). These are Eu- ropean weeds, the first a spiny, semiclimbing shrub, and the second, a chamaephytic herb. Both have wide ecological ranges, colonizing any disturbed site in central-southern Chile. Another European species, Holcus lanatus, was found in seven of the eight associations studied. In six associations, Plan- tago lanceolata, another European herb, was found along with Aristotelia chilensis and Eucryphia cordifolia, two native woody species. Native species with a frequency of five, that is, which occur in five associations, are: Aextoxicon punctatum, Luma apiculata, Baccharis race- mosa, Lapageria rosea, Cissus striata, Boquila trifoliolata, and Blechnum hastatum. The first two are arboreal species of forests and scrubland; the third is a small shrub fairly frequent in the south of Chile. The remaining three are vines that TABLE 4.

It is an ag- gressive, woody plant whose control poses a serious problem in the study region (Ramirez, 1973). The importance of these two shrubs, which belong to disclimax communities, indicates the degree of an- thropic intervention found in the vegetation of Ru- camanque. They invade areas when the forest has een cut, and in this case make difficult the re- generation of the original forest community (Ra- mirez et al., Third in order of importance is “olivillo”” (4ex- toxicon punctatum), a tall tree that forms ever- green forests in the lowest and deepest parts of Rucamanque Valley.

Chus- quea coleu and C. quila are used in crafts and for the construction of furniture and household articles. To fasten pieces of these bamboos, “vo- quis” (Boquila trifoliolata and Campsidium val- divianum) serve as ties. Juncus procerus is used to make mats. From Luma apiculata, tool handles are cut, and the wood of Embothrium coccineum is carved. Applications as construction materials are im- mannia trichosperma. Tannins for the leather tan- ning industry are obtained from the barks of Persea lingue and Weinmannia trichosperma.

Eucryphia cordifolia is valued for domestic firewood, and for this reason the tree is being cut so extensively that it risks local extir- pation. Edible fruits grow on Lapageria rosea, Chile's national flower. “Maqui cider" is made from the berries of Aristotelia chilensis. Edible fruits also grow on Gevuina avellana, Ribes trilobum, Fragaria chiloensis, Ugni molinae, Fuchsia ma- gellanica, and Peumus boldus. The fruits of Ru- bus constrictus are used to make ja The bark of Dasyphyllum e al- legedly regulates blood sugar; Boquila trifoliolata is applied for eye infections; Peumus boldus is used for stomachaches and liver illnesses; an in- fusion of Tristerix tetrandrus is ipe di to reduce cholesterol in the blood. Solanum gay a reputed febrifuge; Buddleja Borsa allegedly | helps eal ulcers; and Equisetum bogotense is used as a diuretic. The following introduced plants have applications in popular medicine: Urtica urens as an antirheumatic, Hypericum perforatum as a vul- nerary, and Mentha rotundifolia and M. pule- gium for the stomach. The rhizomes of Dioscorea brachybotrya are edible and high in starch. Maytenus boaria and Chusquea quila provide excellent winter forage. LITERATURE CITED ANazco, N., M. Moraca & C. Ramirez. 1981.

Gustavo A. Romero?? and Germán Carnevali?^ ABSTRACT Six new orchids from Venezuelan Guayana are described and illustrated, including three species, Coryanthes at cataniapoensis, Catasetu zii, and Catasetum parguaz ybrid, Catasetum X dunstervillei, three hybrids involve four sympatric Catasetum species with overlapping flowering seasons that share Eulaema cingulata (Fabricius) as their main pollinator This paper and others in preparation precede the publication of a comprehensive treatment ‘a the Orchidaceae of southern Venezuela for J. Steyermark’s Flora of the Venezuelan oe (Carnevali et al., in prep.). The taxa described here belong to two of the most complex genera in the Orchidaceae, Coryanthes Hook. and Catasetum Rich. Species in these two genera are extremely variable, and in the Venezuelan Guayana many closely related species are sympatric or syntopic, e pollinators, and have overlapping flowering seasons; natural hybrids are common. alf of the taxa proposed here are natural hy- brids. The parentage of these nothospecies was inferred from pollination data, phenological data, and morphological characters. This approach has its limitations, but one can postulate safely parent species if a large number of specimens of the sus- pected hybrid are examined, because, as Hurst (1902) indicated, “In orchid hybrids of the first generation single specific characters are inherited in all degrees of blending, forming, on the whole, a perfect series between the respective characters of the two parents." In Catasetum x wendlingeri Foldats, the parentage was confirmed by artificial hybridization experiments (A. Pardo, pers. comm., Coryanthes cataniapoénsis G. Romero et Car- nevali, sp. nov.

It flowers from January to June and is pollinated around Puerto Ayacucho, T. F. Amazonas, Venezuela, by Eulaema cingulata (Fa- bricius) and, less frequently, by E. meriana (Oliv- ier) (G. A.

Carnevali 2614 (VEN); Distrito Piar, on tributary to Río Carrao, ca. 10 mi. above Canaima and Rio Churün, G. C. K. Dunsterville 259 (line drawing, AMES). Etymology. Named after the Rio Parguaza, where the type of the species was collected. This species has been collected several times in the Venezuelan Guayana and in Brazil (see color photograph in Miranda, 1987). In the past it had been assigned incorrectly to C. bicallosum Cogn. (Dunsterville & Garay, 1979: 78; Foldats, 1970: 58; Miranda, 1987), a species from the upper Rio Orinoco closely related to C. barbatum Lindley. The type specimen of C. bicallosum Cogn. in the Cogniaux Herbarium (BR, photo) and the original description clearly show this affinity. Catasetum 458 Annals of the Missouri Botanical Garden parguazense belongs in the C. callosum Lindley alliance (Pabst & Dungs, 1975: 172). It differs from C. callosum by having a subcordate labellum and truncated basal callus, and it differs from C. poriferum Lindley (see color photo in Fergusson, 1967) by having long, fully developed antennae and a labellum with erect-patent lateral lobes. It is further distinguished by flowering almost invariably from the developing leaf shoot. Catasetum x dunstervillei G.

Named in honor of G. C. K. Dunsterville, who first illustrated this hybrid in his series coauthored by L. A. Garay, Venezuelan Orchids Illustrated. This natural hybrid has been previously assigned to Catasetum fimbriatum (Morren) Lindley (Dun- qi & Garay, 1966: 42; 1979: 85; Foldats, 1970: 80). However, three lines of evidence reveal C. x dunstervillei as distinct. First, northern South America lies outside the known geographical range of Catasetum fimbriatum: southeastern Brazil, southwestern Bolivia, Paraguay, and northern Ar- gentina (Bicalho, 1965; Dodson, 1978). Second, typical C. fimbriatum from southern Brazil differs considerably from Catasetum X dunstervillei in having a column with long antennae; a long, apic- ulate, acuminate clinandrium; an apiculate, fleshy anther; and a labellum with the fleshy mid-lobe projected forward (see Vasquez & Dodson, 1982). Third, based on fragrance and pollinator data, Catasetum Xdunstervillei cannot be assigned to C. fimbriatum. Hills et al. (1972) showed that C. fimbriatum is a poor fragrance producer with a fragrance spectrum unlike any other species in the genus. Moreover, the only known C. fimbriatum pollinator is Eufriesea auriceps (Friese) (Pijl € Dodson, 1966: 182). Catasetum X dunstervillei, in contrast, produces a fragrance that attracts Eu- laema cingulata, one of the pollinators of Catase- tum discolor Lindley, C. longifolium Lindley, and in general the C. maculatum Kunth complex (Wil- liams & Whitten, 1983). Catasetum X dunster- villei was also compared with C. fimbriatum var. cogniauxii L. Linden, described from material pre- sumably collected in Venezuela (Linden, 18954). A plate in Lindenia (Linden, 1895b) and Cog- niaux's sketches in the type sheet (BR, photo) reveal Catasetum fimbriatum differing from C. x dunstervillei in the characters presented above. Dressler (1976) pointed out that Dunsterville 748, assigned here to Catasetum X dunstervillei peia in Dunsterville & Garay, 1966: 42; 9: 85), was a hybrid between Catasetum pi- d and C. discolor, but he never proposed a binomial. Dressler's hypothesis is supported by two lines of evidence. The flowers of C. x dunstervillei are intermediate between Catastum pileatum and C. discolor, and these two species are by far more abundant than any other possible parent species Volume 76, Number 2 1989 Romero & Carnevali 459 Orchid Flora of Southern Venezuela found in the general area where C. X dunstervillei has been collected, as indicated by plant sampling and by the frequency of their pollinaria on euglos- sine bees (G. A. Romero, unpubl. data). Further- more, Catasetum pileatum and C. discolor share euglossine bee pu and have overlapping flowering season Dodson d that Dunsterville 748 was a hybrid between Catasetum longifolium Lindley and C. macrocarpum Rich. ex Kunth. (Dodson, 1978), based on plants collected in Dawa, Guyana (also pictured in Tan, 1971, fig. 8). However, the plant illustrated in Dodson (1978) differs from C. x dun- stervillei in the pendent habit, the long and narrow leaves, and the labellum morphology. Catasetum X dunstervillei is similar to Cata- setum Xissanensis Pabst (a natural hybrid be- tween C. pileatum and C. longifolium, Pabst, 1975) but is distinguished by the shorter and wider leaves and the labellum with a V-shaped callus. Catasetum X dunstervillei flowers from the ma- ture pseudobulb from August to December. The pollen donor in C. X dunstervillei is most likely C. discolor: the large pollinia of C. pileatum could not fit in the narrow stigmatic cleft of C. discolor. Catasetum Xroseo-album (Hook.)

Bunting 102649 (VEN). Etymology. The specific epithet probably re- fers to the rose and white flowers in the original description. Natural hybrids between Catasetum discolor and C. longifolium were expected in the Vene- zuelan Guayana: the two species are separated by less than the flying range of euglossine bees (1-5 km), they share male euglossine bee pollinators, Eulaema meriana (Olivier), E. bombiformes (Packard), and E. cingulata (Fabricius), and they have overlapping flowering seasons. Around Puerto Ayacucho, Venezuela, the same species of Eulae- ma bees have been caught carrying the very dis- tinct C. discolor and C. longifolium pollinaria in late February through May. The pollinaria of both » species are placed on the ventrum of the bees thorax, but C. discolor pollinaria have a dark brown stipe and a very small viscidium (narrower than the involute stipe), whereas C. longifolium polli- naria have a light brown stipe and a large viscidium (wider than the involute stipe). Plants bearing flow- ers intermediate between the two presumed parents had been collected in the Venezuelan Guayana, Guyana (Dodson, 1978), and Brazil (Mansfeld, 1932) and were assigned previously to Catasetum discolor var. roseo-album (Hook.) Mansf. Dodson (1978) suggested that this taxon may have resulted from a natural cross between Catasetum discolor and C. longifolium, but he never changed its no- menclatural status to that of nothotaxon. Catasetum X roseo-album is widespread in low- land "morichales" (gallery forest communities dominated by Mauritia flexuosa L.f.) in the north- western Venezuelan Guayana, where it occupies typical C. longifolium habitat, growing near the crown on the stems of Mauritia flexuosa. It is also found on Bactris sp., and on dead trees in sea- sonally flooded forest. The hybrid differs from C. longifolium by hav- ing generally erect (vs. pendulous) habit; leaves 6— 20 cm long, 4-7 cm wide and generally 5-nerved (vs. 15-150 cm long, 1-3 cm wide, and 3-nerved), shortly apiculate, apically incurved (vs. obtuse and flat) clinandrium of the staminate flower, and the C. discolor-like pollinarium. The hybrid differs from C. discolor in the epi- phytic habit, generally arcuate to pendent stami- nate inflorescence (always erect in C. discolor), and deeply galeate, dorsally compressed labellum of the staminate flower (shallowly concave and globose in C. discolor). Pistillate flowers of the hybrid are often distinguished by the deeply galeate labellum (globose in C. discolor) but can vary be- tween C. discolor-like to C. longifolium-like (deep- ly saccate), ranging in color from light green (yel- low-green in old flowers) to deep maroon. The hybrid staminate flowers vary in color between pinkish white to green, purple, orange, or maroon. 460 Annals of the Missouri Botanical Garden Catasetum X roseo-album flowers from the ma- — dulate-dentate. The hybrid differs from C. pilea- ture pseudobulb from June to January. Pollen flow between either parent is likely, as the pollinia of both species are of similar size.

Etymology. Named after K. Wendlinger, who cultivated the plant featured in the original de- scription. C. H. Dodson first proposed this natural hybrid between Catasetum pileatum and C. planiceps (quoted in Dunsterville & Uzcategui, 1981) based on the floral morphology of the G. C. K. Dun- sterville 1413 specimen cited above. Dodson, how- ever, never proposed a binomial. Since then, plants resulting from the artificial cross between the pre- sumed parents flowered in the collection of A. Par- do in Venezuela, and three more specimens of the presumed natural hybrid were collected around Puerto Ayacucho. Comnarison of the staminate flower of the artificial hybrid with the holotype of Catasetum wendlingeri and C. planiceps (K, pho- to) showed it to be more similar to C. wendlingeri; in fact, some of the hybrids were identical to C. wendlingeri. Catasetum wendlingeri had been treated previously as a synonym of C. planiceps (Foldats, 1959; 1970: 97; Schweinfurth, 1967). Catasetum X wendlingeri differs from C. plani- ceps in the epiphytic habit and in the generally larger staminate flower with the labellum apex broadly patent or reflexed and the column with a long, apicular clinandrium. Further, the staminate flowers of the hybrid are sometimes resupinate (as in G. C. K. Dunsterville 1413 and G. A. Romero & L. Rojas 1201), or the margins of the labellum are fimbriate (as in G. C. K. Dunsterville 1413, illustrated in Dunsterville & Uzcategui, 1981), whereas the staminate flowers of C. planiceps are never resupinate and the margins crenate or un- tum in the hooded labellum and the bilaterally symmetrical antennae of the staminate flowers. Catasetum X wendlingeri flowers from the de- veloping leaf shoot from April to July. This hybrid, as is its proposed parent species, is pollinated by Fulaema cingulata. The pollen donor of the hybrid is most likely Catasetum planiceps; C. pileatum pollinia could not be inserted in the narrow stig- matic cleft of C. planiceps. LITERATURE CITED BicaLHo, H. D. 1965.

Henk van der Werff* ABSTRACT Eleven new species (Licaria n Ocotea flavantha, O. liesneri, O. glabra "roatii, P. croizatii, and P. fluviatilis) are described. Ocotea julianii is for Phoebe peint Phoebe areolatocostae is transferred to Persea, and Ocotea o ulata, O. tomentosa, published as a new name steyermarkiana is transferred to Rhodostemonodaphne , O. huberi, O. megacarpa, O. During the preparation of the treatment of the Lauraceae for the Flora of the Venezuelan Guaya- na, a number of collections were found that ap- peared to represent undescribed taxa. Most of these collections were gathered during recent expeditions and are of high quality. As can be expected, there are, after completion of the family treatment, still several sterile or fruiting collections that do not match any of the known species from Guayana and that represent additional or even undescribed species. These species could not be included in the treatment for lack of adequate collections. In general, the Lauraceae in Venezuelan Guaya- na are still undercollected. Of the 128 species (Nectandra excluded; this genus will be contributed by Dr. J. Rohwer), 55 are known only from one or two collections, while an additional 13 are known from three or four collections. This large number of rarely collected species suggests that there are still several additional species to be collected and that our knowledge about Lauraceae in Venezuelan Guayana is far from complete. The available data show that about one-third of the species (41 out of 128) are endemic to Guaya- na. Of these 41, 31 species occur on the slopes and summits of the tepuis, while 10 are lowland species. The number of endemic lowland species will likely diminish when adjoining Colombia and Brazil are better explored, because I expect that lowland species such as Ocotea tomentosa, Persea fluviatilis, and Phoebe semecarpifolia, which oc- cur near the borders with Colombia and Brazil, are not restricted to the Venezuelan side of the borders. w species, combinations, and the new name are arranged in alphabetical sequence.

The tepals in front of the stamens (whorl III) are absent, and it is likely that staminodia representing whorl I would have fallen off as well. At present, Licaria tomentosa is known only from the holotype in NY (with detached cupules) and sterile isotypes in COL and F.

The color of the indument and the smooth upper leaf surfaces suggest a relationship with the more restricted O. bracteosa (Meissner) Mez, O. cujumary Martius, and O. canaliculata (Rich.) Mez. These three species in Venezuela are known only from the eastern parts of T. F. Delta Amacuro and Estado Bolivar. Ocotea cujumary can be readily identified by its double-rimmed cu- pules; the other two species differ from O. flavan- tha in their glabrous ovary and style and in the absence of leafless, but inflorescences-carrying ter- minal parts of the twigs. The swollen pedicel sup- porting the cupule and the rather large (and still immature) cupules are additional distinctive char- acteristics. Differences in leaf shape are rather subtle. Ocotea canaliculata has the petiole poorly differentiated and lacks the weakly recurved leaf base, while O. flavantha has an obvious petiole and a slightly recurved leaf base. Ocotea bracteosa has larger and wider (to 15 x 6 cm) and more glaucous leaves than O. flavantha. Ocotea glabra van der Werff, sp. nov. TYPE: Venezuela.

Ocotea glabra is known only from two collec- tions from the summits of Carrao- and Caraurén- tepuis. It is characterized by being completely gla- brous, its (narrowly) obovate leaves, and its ve- nation with lateral veins departing at almost 90? from the midvein. This last-mentioned character occurs also in O. wurdackiana Allen, a species restricted to the tepuis of Estado Bolivar. Allen (1964) cited the type collection of O. glabra as a paratype of O. wurdackiana and described O. wurdackiana as having hermaphrodite flowers. Recent collections have shown that O. wurdack- iana has unisexual flowers, like O. glabra. The two species, although superficially similar, can be separated as follows: O. glabra is entirely glabrous and has the lower leaf surfaces smooth, while wurdackiana always has a pubescent terminal bud, the inner surface of tho tepals densely pubescent, Ilat mate. and the lower leaf Ocotea glabra has its closest bie amon the ten unisexual Ocotea species in the Venezuelan Guayana that share glabrous twigs, leaves, and terminal buds. Two of these have pubescent flowers or inflorescences (O. myriantha (Meissner) Mez and O. perrobusta (Allen) Rohwer) and are not very closely related. Ocotea myriantha is a low- land species, rather common in southern T. F. Amazonas, whereas O. perrobusta is restricted to Auyan-tepui, Estado Bolívar. The remaining species in this group have a restricted distribution and are known only from the upper slopes or summits of one or two sandstone mountains. Three have rather large, many-flowered inflorescences: O. crassifolia (Sarven-tepui, Roraima), O. neblinae (Neblina), and O. basirecurva (Serranía de Yutaje, Cerro Coro-Coro). Short, almost spicate, and few-flowered inflorescences, also strongly coriaceous leaves, characterize the last large group of species. Several t not all species in this group have glaucous, clustered, almost sessile leaves, shiny upper leaf surfaces, and lobed or toothed cupules. This group can be subdivided into (1) species from Estado Bolivar, characterized by immersed or elevated costa and lateral veins but without a raised reticula- tion (O. erectifolia (Allen) van der Werff, Cerro Jaua; O. glabra van der Werff, Carrao-tepui and Caraurén-tepui; O. roseopedunculata van der Werff, Acopan-tepui), and (2) species from T. F. Amazonas with weakly developed lateral veins and raised reticulation on upper and/or lower leaf sur- face (O. venosa Gleason, Cerro Duida, Marahuaca; O. cowaniana Allen, Serrania Paru; O. huberi van der Werff, Cerro Coro-Coro, Serrania Guanay). Ocotea glaucophylla Moldenke, based on material from Cerro Duida, is not well understood; to this small-leaved species also belong collections from Chimantá, revealing an unusual distribution pat- tern. With the exception of O. glaucophylla, these species are well defined by their inflorescence and leaf characters (Fig. 3); they are also geographi- cally separated, and the paucity of collections is probably due to occurrence in inaccessible places. The collection Maguire 33026 (NY) from Cerro Guaiquinima belongs in this species group (it has glabrous leaves, twigs, and terminal bud, and clus- tered, glaucous, coriaceous, subsessile leaves) and differs from the other species in its smooth upper leaf surface; it is almost certainly undescribed, but because it is sterile, I do not wish to describe it.

VENEZUELA. T. F. AMAZONAS: Depto. Atures, cumbre del Cerro Coro-Coro, 2,200 m, Huber 12298 (MO, MYF). Ocotea huberi is restricted to the Departamento Atures and Distrito Cedeño, along the border of Estado Bolivar and T. F. Amazonas. Its closest relative is O. venosa Gleason, a species only known from the type collection from Cerro Duida and a fruiting specimen from Cerro Marahuaca, both in . Amazonas. The two species have similarly id reticulation, toothed or lobed cupules, and swollen fruiting pedicels. They differ in their leaf bases, which are obtuse in O. venosa vs. rounded to cordate in O. huberi, and in the much shorter inflorescences of O. venosa. The types of O. venosa (NY, US) do not have open flowers, and I have not compared their floral details; I accept O. huberi as a distinct species based on its striking leaf shape and long inflorescences. The group of species to which Ocotea huberi belongs is characterized by unisexual flowers. The MO sheet of Huber 11008 has two twigs, one in young fruit, the other in flower. Dissection showed the flowers to be staminate (anthers with well-de- veloped locelli; pistil hollow). Thus, the flowering and fruiting twigs on the type sheet probably came from different plants, and I select the flowering twig as the holotype. ipsias ee of O. huberi are further discussed under O. gla Ocotea julianii van der Werff, nom. nov. Based on Phoebe steyermarkiana Allen, Mem. New York. Bot Gard. 10(5): 74. 1964. TYPE: Stey- ermark & Wurdack 921 (holotype, NY; iso- types, F, MO). Ocotea julianii was erroneously described as belonging to the genus Phoebe by Allen. The large, cup-shaped cupule excludes this species at once from Phoebe, a genus in which the fruit is sub- tended by a small cupule with the tepals usually persisting. Leaf venation, the large cupule, and the deep floral tube in old flowers all point to the Ocotea aciphylla group (I have not seen good flowering material). Because Allen already described Ocotea steyermarkiana, a new epithet is needed when Phoebe steyermarkiana is transferred to Ocotea. The similarity between Ocotea julianii and Phoebe tetragona (Meissner) Mez pointed out by Allen (1964) is superficial. Fruiting specimens of the latter species have a cupule typical of Phoebe, and the leaves and flowers are glabrous. Distri- bution also argues against a close relationship, since P. tetragona is a cerrado species from Minas rais, Brazil. I regard O. julianii as closely related to O. revoluta Moldenke, a poorly known species from Cerro Duida. This species differs in its nar- rower, generally smaller leaves with revolute mar- gins and in its smaller, funnel-shaped cupules; both species belong to the O. aciphylla group.

Although Ocotea liesneri, known only from the type collection, is in all vegetative parts glabrous like Ocotea erectifolia and allies, these species are probably not closely related. Ocotea liesneri differs from the O. erectifolia group, for instance, by having well-developed petioles, a rather lax inflo- rescence (comparable to but smaller than that of O. basirecurva), relatively long and pubescent fil- aments, and flowers apparently hermaphroditic. The last-mentioned character, difficult to ascertain, needs verification from additional collections. Oco- tea liesneri seems quite isolated. In the Venezuelan Guayana, the number of hermaphroditic Ocotea species is not great; most belong to the O. aci- phylla group, which always has pubescent flowers and a quite different venation, and the O. oblonga group, which has entirely different leaves. The remaining species are also isolated and possess some striking characters; they include O. rubra Mez, O. cymbarum esmeraldana Moldenke, and O. fasciculata (Nees) Mez.

However, in addition to its smaller fruits and cupules, O. julianii differs in its rounded to subcordate leaf bases, short, thick petioles, and blunt to rounded leaf apices. Ocotea megacarpa is in leaf shape (but not in indumentum) very similar to O. aciphylla (Nees) Mez s.l., lowland populations in T. F.

Ocotea roseopedunculata is restricted to Aco- pán-tepui and is currently known from only two collections. Its nearest relative is Ocotea glabra, known from Carrao and Caraurén-tepuis in Estado Bolivar. These two species are best separated by their leaf characters: O. roseopedunculata has elliptic leaves with mostly ascending lateral veins, while O. glabra has (narrowly) obovate leaves with the lateral veins leaving the midrib under a blunter angle and more rounded leaftips. In sme ae there are some small floral differences: in O. glabra the filaments and anthers of the outer stamens are about equally long and the pistillode is ca. 0.8 mm ong; in O. roseopedunculata the anthers are sub- sessile and the pistillode is smaller, 0.3 mm long. The two species share ridged stems, conspicuous leaf scars, almost spicate, few-flowered inflores- cences, and a tendency toward clustered leaves. See also discussion under O. glabra.

Ocotea tomentosa is known only from the upper drainage of the Río Negro between Maroa and San Carlos de Rio Negro. Although the area around San Carlos de Río Negro has been reasonably well explored, O. tomentosa has only been collected there twice (both collections from the same marked tree) and is apparently rare. It is very likely present in Colombia and can be expected in Brazil. The angled twigs, somewhat clustered flowers and, above all, scarce pubescence on the tepals in comparison with that on the inflorescence point to the Ocotea leucoxylon group as the closest rela- tives. None of the species in that group has leaves with dense abaxial tomentum or such persistent tepals in the fruiting stage; moreover, O. tomentosa lacks the white lenticels on the cupule that so readily identify the O. leucoxylon group. Persea areolatocostae (Allen) van der Werff, comb. nov. BASIONYM: Phoebe areolatocostae C. K. Allen, Mem. N.Y. Bot. Gard. 10: 75 1964. The type collection of Phoebe areolatocostae has buds and immature fruits. However, the fruits are diseased; the relatively long petioles, leaf shape, and leaf reticulation all point to the genus Persea. The equal tepals are a character infrequently found in Persea; P. americana and a few related species share this character, but P. areolatocostae is prob- ably not related to those species. In my opinion, the relationship is with a small group of species characterized by equal tepals, a small, round fruit, and persistent tepals in the fruiting stage. This group includes the neotropical P. steyermarkii, P. rigens, P. silvestris, and a few additional, as yet undescribed, species. It is not yet clear to which degree this group is related to the Asian Persea subg. Machilus. Persea croatii van der Werff, sp. nov. TYPE: enezuela. T. F.

In Kopp's (1966) revision of the neotropical Persea species, P. croizatii keys to her section Kriodaphne because of its glabrous ovary.

Persea fluviatilis is known only from periodi- cally inundated forest in Territorio Federal Ama- zonas, Venezuela, at elevations of about 100 m. In Kopp's (1966) revision of the neotropical species of Persea, it keys to section Heteranthera because the stamens of whorl III are sterile. Within that section, it is closest to P. meridensis, a poorly known Andean species, which differs in its ferru- ginous pubescence, pedicelled flowers, and solid twigs. Unusual characters of P. fluviatilis are the subequal tepals, hollow twigs, clustered leaves, dif- ference in pubescence between the young and old twigs, and swollen pedicels in fruit. Because many of the neotropical Persea species are infrequently collected and are poorly known, close relatives of this distinctive species have not been pinpointed. The swollen pedicels in fruit are a very unusual feature, but because there are only two fruiting collections known, it is possible that this condition is caused by a disease and is not typical for the species. At the time of her revision Kopp had only a fruiting collection of this species at hand, which she cited as P. nivea Mez, a species that does not occur in Venezuela.

A study of the available collections of O. steyer- markiana shows that this species has all the char- acters of Rhodostemonodaphne, and therefore a new combination is made. I did not find that the outer stamens have distinct filaments and that the anther cells are arranged in two rows, as Allen described and illustrated. Pubescence and inflores- cence type suggest that RA. steyermarkiana is closely related to R. celiana (Allen) Rohwer and ndlicheria vinotincta Allen, both endemic to the Venezuelan Guayana. I include two collections from Cerro Sarisarinama, cited by Bernardi in Steyer- mark (1976) as O. celiana Allen and O. ferruginea (Meissner) Mez, in R. steyermarkiana. LITERATURE CITED C. K. 1964.

In order to clarify relationships within this large and com- plex group, a preliminary cladistic analysis of the axillary-flowered taxa of Miconieae was conducted as reported here Within the Miconieae, the inflorescence may be either terminal or lateral. Plants with terminal in- florescences have hapaxanthic shoots in which the apical meristem of the shoot becomes wholly trans- formed into a flowering axis after a period of veg- etative growth, while plants with axillary inflores- cences have pleonanthic shoots in which the apical meristem continues its vegetative activity while producing lateral flowers or inflorescence axes (see Judd, 1986a; a UN Inflorescence po- sition, along wit at t f growth architecture, has been shown to be a valuable taxo- nomic character in the tribe and is usually uniform within sections or genera (Judd, 1986a). The axillary-flowered condition is likely a de- rived state within the Miconieae because nearly all members of the Merianieae show terminal flowers. The latter tribe is a reasonable outgroup taxon considering possible tribal relationships suggested ' This research was supported by NSF Grant BSR-8406760.

Volume 76, Number 2 1989 Judd Miconieae by J. Wurdack (Welle & Koek-Noorman, 1981). The same conclusion would be reached through the use of a generalized melastomataceous out- group and the tree counting algorithm of Frolich (1987), since terminal cymose inflorescences are the strongly predominant condition within non-Mi- conieae melastomes. Terminal inflorescences occur in over 80% of non-Miconieae genera, and strongly predominate in all tribes except the Blakeeae Benth. & Hook. f. In addition, Weberling (1988) noted that all melastomes show monotelic inflorescences, with the basic form being a pleiothyrsoid termi- nating a leafy shoot. In this study the monophyly of the axillary-flowered Miconieae was accepted as a useful preliminary hypothesis and a cladistic anal- ysis of these taxa was conducted. The results of this analysis are then used to suggest generic re- alignments and to reevaluate the preliminary hy- pothesis of monophyly of the axillary-flowered taxa. CLADISTIC ANALYSES METHODS The cladistic analyses were conducted using the Wagner parsimony algorithm (with global branch- swapping and multiple parsimony options) of the PAUP (i.e., Phylogenetic Analysis Using Parsi- mony, Version 2.4; Swofford, 1985) package of computer software. Fifteen Evolutionary Units (EUs) were used in most of the analyses (Table 1), based on a survey of ca. 370 herbarium specimens representing 150 species (and supplemented, where possible, by the addition of information from recent taxonomic studies). Several taxa also were studied during the course of fieldwork in Haiti, the Dominican Re- public, Puerto Rico, and Jamaica. In some anal- yses, an additional EU representing either a gen- eralized terminal-flowered taxon or Clidemia sect. Miconiopsis Cogn. was used. Although terminal- flowered, Clidemia sect. Miconiopsis has been considered to be related to the other sections of Clidemia included in this study, and its inclusion in a few analyses was designed to test this hypoth- esis. The inclusion of a generalized terminal-flow- ered taxon in some analyses was designed, in a very preliminary way, to evaluate the hypothesis that the axillary-flowered Miconieae are monophy- letic. Placement of this generalized terminal-flow- ered taxon is considered very tentative because this EU is extremely heterogeneous, making the determination of its ancestral character states prob- lematic (see Table 1). Forty-two characters were used and assigned plesiomorphic (ancestral: scored as 0) and apo- morphic (derived: scored as 1) states (Table 1). Apomorphic features used in the computer analyses are listed below. Nearly all characters were polar- ized using the Merianieae as an outgroup, with character states uniformly found (or, for a few characters, those states most commonly repre- sented) in the out-group considered plesiomorphic (Stevens, 1980; Wheeler, 1981; Wiley, 1981; Maddison et al., 1984; Frolich, 1987). When EUs are polymorphic for a given character, an estimate of the ancestral condition was made. The states of a few characters were unknown for certain taxa, and these are scored as “missing data," indicated by a “?” in the data matrix (Table 1). Trees were rooted by using a hypothetical ancestor with all characters scored as plesiomorphic. APOMORPHIC CHARACTERS 1. Stems quandrangular and 4-winged/ ridged; plesiomorphic condition: stems + terete. Quadran- gular stems are considered an autapomorphy of Killipia Gleason and occur in K. quadrangularis Gleason (the type species). However, two other species have terete stems, and the ancestral con- dition within Killipia is not known. A coding of "0" for this EU would not affect the analyses because the feature is autapom i 2. Growth pleonanthic Lr plesio- morphic condition: growth hapaxanthic (determi- nate). (See character 12.) 3. Megastyloid crystals present; plesiomorphic condition: only small styloids and/or druse crystals present. (See character 4.) 4. Crystals exclusively druses; plesiomorphic condition: small or large styloids and druse crystals present. The polarity of characters 3 and 4 was determined by using the Crypteroniaceae (Dahl- gren & Thorne, 1984) as an outgroup (see dis- cussion in Johnson & Briggs, 1984; Vliet et al., 1981). This family, which is closely related to the Melastomataceae, contains genera with druses and with small styloids (Baas, 1981), and this crystal complement is taken as the ancestral condition in melastomes. It is likely that megastyloids have evolved in a few lineages (sometimes with the loss of druses), while styloids have been lost in other lineages, resulting in druses being the only crystal type in those groups. That styloids and druses are known from more distantly related families of Myr- tales, such as Myrtaceae and Combretaceae (Vliet & Baas, 1984) supports this polarity. Variation in crystal complement within the Merianieae is poorly known. 5. Elongate multicellular hairs absent; plesio- 478 Annals of the Missouri Botanical Garden TABLE 1.

Mecranium Hook. f. an Killipia are unique in lacking a well- da indumentum. A few species of Loreya DC., L. ovata Berg ex Triana, L. arborescens Gann and L. nigricans Triana, lack such hairs as wei je (in press) hypothesized the loss of strigose hairs to be a synapomorphy of a species group within Loreya. Thus, the presence of such hairs is considered the ancestral condition within the genus. 6. Multicellular hairs elongate with radiate to stellate-globular basal portion (or clearly derived types); plesiomorphic condition: multicellular hairs various, but not as above. This distinctive hair morphology is much modified (see discussion, and Judd, 1986b) in a few species, but such extremes are connected by intermediate types, sometimes even on the same plant. 7. Multicellular hairs minute, globular, and un- branched to irregularly branched and matted (not strigose); plesiomorphic condition: multicellular hairs various but not as above. This character is limited to Mecranium (including Ekmaniocharis Urban) and Ossaea acuminata The feature is im- portant in determining that Mecranium spp., saea acuminata, and Ekmaniocharis crassinervis Urban form a monophyletic group but does not help in inferring relationships among the EUs. 8. Multicellular hairs conspicuously stellate (with stalk and elongated arms); plesiomorphic condition: multicellular hairs various but not as above. In these analyses this feature is considered an autapo- morphy of Clidemia sect. Miconiopsis. Very sim- ilar hairs occur in many terminal-flowered species, ., Miconia sects. Jucunda (Cham.) Naudin and Tamonea (Aublet) Cogn. 9. Leaves clearly anisophyllous; plesiomorphic condition: leaves isophyllous or nearly so ew specialized species of Clidemia sect. Sograt (DC.) ogn. have anisophyllous leaves. The isophyllous condition is considered ancestral within Clidemia sect. Sagraea, following a preliminary analysis of variation within the group. 10. Leaves with pair of pouchlike formicaria at base of blade; plesiomorphic condition: leaves lack- ing formicaria. Similar ant-domatia that occur in terminal-flowered taxa, e.g., Tococa Aublet, Cli- demia D. Don, Myrmidone Mart., probably evolved independently (see discussion). Ossaea bullata (Pil- ger) Gleason, possibly a member of the Sagraea group, has been reported to possess similar for- micaria (Whiffin, 1972). 11. Cuticle of abaxial leaf epidermis papillose; plesiomorphic condition: epidermis nonpapillose. Renner (in press) pointed out that this feature cor- relates well with cuticle thickness and suggested that the character has important ecological con- sequences. 12. Inflorescences axillary (in leaf axils or at nodes on old wood); plesiomorphic condition: inflo- rescences terminal. Terminal cymose inflores- cences (as discussed above) occur in over 80% of genera within non-Miconieae melastomes. Thus, proliferating inflorescences (in which the terminal axis returns to vegetative growth, producing axil- lary buds that develop vegetative branches instead of flower-bearing paracladia—see Weberling, 1988) are considered derived. The process of proliferation results in a vegetative shoot in which the flowers are borne in axillary cymose paracladia. Delayed anthesis of the paracladia can even result in cau- liflory. 13. Inflorescences condition: inflorescences cymose. Although fasci- cles occur in a few species of Loreya, Clidemia fasciculate; plesiomorphic sect. Sagraea (including axillary, 4-merous species of Ossaea DC.), and the 5-(6-)merous species of Ossaea, cymose inflorescences are considered to be the ancestral condition in these groups. Renner (in press) also considered fasciculate inflorescences to be derived within Loreya. 14. Flowers more or less sessile; plesiomorphic condition: flowers pedicellate. 15. Flowers 4-merous; plesiomorphic condition: flowers other than 4-merous. (See character 16.) 16. Flower parts frequently more than 5; ple- siomorphic condition: flowers 4- or 5-merous. Gen- erally, 5-merous flowers are considered primitive, with higher and lower floral numbers treated as derived. Henriettea DC. and Loreya contain a few species with numerical plans greater than five, while Henriettella Naudin and Kirkbridea Wurdack sidered ancestral. Renner (in press) considered flo- ral numbers greater than five to be derived and used this feature to link some species of Loreya with Bellucia Raf. The ancestral condition in Kirk- bridea is in doubt; however, recoding the state of this EU as “1” for this character does not change the topology of the discovered cladograms. 17. Flowers small; plesiomorphic condition: flowers moderate to large. 18. Hypanthium strongly ribbed; plesiomorphic condition: hypanthium nonribbed. This character is an autapomorphy of Clidemia sect. Calophy- soides Cogn. 19. External calyx lobes more or less conspic- uous and well developed; plesiomorphic condition: external calyx lobes absent or inconspicuous. 20. External calyx lobes absent; plesiomorphic 480 Annals of the Missouri Botanical Garden condition: external calyx lobes present. Some species of Henriettella have lost external calyx lobes in- dependently of the loss in Loreya, Bellucia, and Myriaspora Is was determined because it is evident that Henriettella evolved out of a group within Henriettea, which has external calyx lobes. 21. Internal calyx lobes very elongate and closely associated with external lobes; plesiomor- phic condition: internal calyx lobes not elongate, variously developed but not closely appressed to internal lobes. This feature is an autapomorphy of Killipia. 22. Internal calyx lobes connate into a mem- branous, dome-shaped, apiculate cap that ruptures irregularly at anthesis; plesiomorphic condition: in- ternal calyx lobes free. This character is an aut- of Mecranium (including Ekmani- Although Ossaea acuminata has somewhat caplike calyx lobes, they are only par- tially connate. The internal calyx lobes are free and imbricate at their extreme apices. This species is included within the Mecranium EU since it has the other apomorphies of this clade (characters 7, 19, and 32; see discussion). 23. Internal calyx lobes circumscissilly dehis- cent (and noncalyptrate); plesiomorphic condition: internal calyx lobes more or less persistent, or if circumscissile, then calyptrate. This character is considered an autapomorphy of Clidemia sect. Mi- included within the generalized terminal-flowered taxon). 24. Buds closed, with thick triangular calyx lobes that cover bud up to the final stage prior to anthesis (and sometimes fused into a cap); plesio- morphic condition: buds open, calyx lobes of vari- able shape and thin, the petals exposed much before anthesis. This feature is an autapomorphy of Bel- ucia 25. Internal calyx lobes reduced to a more or less smooth rim; plesiomorphic condition: internal calyx lobes clearly evident. This is a noninformative character (see Table 1) because it is found only in a few derived Vll within Henriettella and Cli- demia sect. Sagraea. Teas de lobes fused into a conical, apically closed calyptra and conspicuously strigose; plesiomorphic condition: internal calyx lobes non- calyptrate (or if so, then not as above). This is an autapomorphy of Myriaspora. 27. Internal calyx lobes fused into an apically open cap (opening into sepal-like segments or cir- cumscissilly); plesiomorphic condition: internal ca- yx lobes noncalyptrate (or if so, then not as above). This feature is limited to Llewelynia Pittier and a few (probably related) species of Henriettea (see discussion). . Calyx a cap open at apex and falling off by circumscissile slit; plesiomorphic condition: ca- lyx not open-calyptrate, or if so, then opening by longitudinal slits into triangular sepal-like segments. This character is an autapomorphy of Llewelynia and is a further specialization of character 27. 29. Petals narrowly triangular and more or less acute at apex; plesiomorphic condition: petals ovate to elliptic (or obovate) with blunt to more or less acuminate apices. Preliminary analyses of variation within Mecranium (including Ekmaniocharis) and Clidemia sect. Sagraea (including axillary, 4-mer- ous species of Ossaea) have led to the conclusion that ovate to elliptic petals with more or less acu- minate to blunt apices constitute the ancestral con- dition within these groups. Obovate petals have evolved within a group of Mecranium species. It is noteworthy that Ossaea acuminata, a narrow- petaled species, is a sister species to Mecranium amygdalinum (Desr.) C. Wright in Sauv., a fairly blunt-petaled species (Skean, in prep.). 30. Petals with a dorso-apical tooth; plesio- morphic condition: petals lacking a dorso-apical tooth. This feature occurs in a few species of Cli- demia sect. Sagraea (including the species of Os- saea with axillary, 4-merous flowers) and in the r 6-merous species of Ossaea. A scoring of «p is this character in these two EUs does not alter their placement in relation to the very dif- ferent Henriettea group. 31. Petals usually pubescent, sometimes only with very few hairs near apex; plesiomorphic con- dition: petals glabrous (or with a single apical hair). Hairs on the petals have been lost in a few species of Loreya and Bellucia. 2. Androecial fringe present; plesiomorphic condition: androecial fringe absent. This feature is a strong and consistent synapomorphy of Mecra- nium species, including Ekmaniocharis crassiner- vis and Ossaea acuminata. . Anthers with two well-developed dorso-bas- al aan: plesiomorphic condition: anthers various but lacking two well-developed dorso-basal projections. 4. Anthers usually robust and fleshy, opening by one or two minute pores; plesiomorphic con- dition: anthers not robust and fleshy, various. 35. Anther sacs basally bifurcate, i.e., sagittate; plesiomorphic condition: anther sacs not bifurcate at base. 36. Anther sacs more or less wrinkled; plesio- morphic condition: anther sacs smooth. The best expression of this feature is in Maieta Aublet. 37. Stamens numerous, i.e., more than twice Volume 76, Number 2 1989 Judd 481 Miconieae the number of petals; plesiomorphic condition: sta- mens twice the number of petals. This is an aut- apomorphic character of Llewelynia. 38. Stigma very conspicuously and radiately ridged; plesiomorphic condition: stigma not radiate- ly ridge 39. Piscenis highly divided; plesiomorphic con- dition: placenta undivided or nearly so. This is an autapomorphy of Myriaspora. 40. Fruit a berry; plesiomorphic condition: fruit a capsule. 41. Chromosome number of n = 28; plesio- morphic condition: n — 17 (or 15, 20). (See char- acter 42.) 42. Chromosome number of n — 15, 20; ple- siomorphic condition: n — 17 (or 28). The terminal- flowered Miconieae were used as a generalized out- group for the determination of polarity of the in- completely known characters 41 and RESULTS Initial computer runs using the entire data set for the 15 axillary-flowered EUs resulted in the discovery of 100-- equally parsimonious trees (but only 15 different topologies when multi-furcations are taken into account), all with a length of 28 steps and a consistency index of 0.714 (or 48 steps and consistency index of 0.813 when autapomor- phies and uniform characters were included). The strict consensus tree resulting from this analysis is presented in Figure 1B. In addition a tree indicating character state changes is presented (Fig. 1A). This tree is preferred due to its pattern of character variation, especially the linking of Mecranium and Clidemia sect. Sagraea on the basis of 4-merous flowers (15), and the linking of Henriettea, Hen- riettella, and Llewelynia on the basis of fasciculate inflorescences (13). The relationships of the EUs representing Loreya, Bellucia, Myriaspora, Hen- riettea, Henriettella, and Llewelynia did not vary in any of the trees generated by PAUP. In addition, Kirkbridea consistently linked with Henriettea, Henriettella, and Llewelynia, in some trees as the cladistically basal member of this clade, in others as the sister group of Henriettella. In all trees, the EUs representing Maieta, Clidemia sect. Calo- physoides, and Clidemia juruensis (Pilger) Glea- son were always joined, and Huilaea Wurdack was always the basal member of the clade representing taxa with only druse crystals. Thus the large num- ber of generated trees is due to the numerous possible topologies among the remaining EUs in the analyses, i.e., Mecranium (including Ekmani- ocharis and Ossaea acuminata), Clidemia sect. Sagraea (including Necramium Britton and axil- lary 4-merous species of Ossaea), Killipia, and Pentossaea, here described to include the axillary- flowered, 5-merous (or less commonly 6-merous) species of Ossaea Thus, several analyses were conducted using just those EUs possessing only druse crystals (i.e., top eight EUs listed in Table 1) with characters not pertaining to this complex deleted. These analyses generated 45 equally parsimonious trees (but com- prising only seven different tree topologies) of 11 steps and with a consistency index of 0.727 when all characters were weighted equally (or of 25 steps and a consistency index of 0.880 when autapo- morphies and uniform characters were included). However, when the apomorphy of 4-merous flowers was stressed (weighted by 2, as seems reasonable, since this character is quite uniform within EUs under investigation), only 15 trees (representing only two topologies) were produced, all with 12 steps and a consistency index of 0.750 (or of 26 steps and a consistency index of 0.889 when aut- apomorphies and uniform characters were includ- ed). The consensus tree resulting from the analysis in which all characters are weighted equally is identical to that produced in the analysis of all axillary-flowered taxa (Fig. 1B). Both cladograms resulting from the weighted-character analysis are given in Figure 1C and D When an EU representing a generalized ter- minal-flowered taxon is included in the analysis, over 100 equally parsimonious trees were found, all with a length of 32 steps and a consistency index of 0.688 (or of 50 steps and a consistency index of 0.780 when autapomorphies and uniform characters were included). These trees are very similar to those generated in the analyses involving only axillary-flowered taxa (Fig. 1), and the four different topologies involving their basal branches are presented in Figure 2, illustrating the various positions of the genus Huilaea and a generalized terminal-flowered taxon. When Clidemia sect. Mi- coniopsis (another taxon producing terminal inflo- rescences) is included in the analysis, many trees are again generated (of 55 steps and a consistency index of 0.745, including autapomorphies), all link- ing this entity with either Killipia or a clade con- taining Killipia, Clidemia sect. Sagraea, and Mecranium. DISCUSSION The cladograms presented in Figures 1 and 2 indicate that the axillary-flowered Miconieae are divided into two major clades. The first is composed of those taxa containing megastyloids (3) in their leaf and stem tissues (often with druse crystals as well) and usually possessing slightly pubescent pet- als (31). The group also generally has distinctly 482 Annals of the Missouri Botanical Garden ME SA KI PE CL MA CA HU LO MY BE KK HL HT LL 5 417 4 26 11 20 1 3 27 19 29 35 18 is 17 17 28 2 5 24 19 32 21 37 33 9 2n 13 33 34 10 15 f 16 38 he 6 42 41 14 17 19 3 à .

Taxon abbreviations: styloid- terminal-flowered taxon (TE). * and druse-containing lineages (see text). pedicellate flowers. This clade may be divided into two clearly marked subgroups based on vegetative and reproductive characters. Loreya, Bellucia, and Myriaspora are united by the synapomorphies of flowers lacking external calyx lobes (20), possessing robust fleshy anthers (34), an expanded and ra- diately ridged stigma (38), and a chromosome num- ber of n = 15 or 20 (42). In contrast, Henriettea, Henriettella, Llewelynia, and Kirkbridea form a clade based upon the presence of multicellular stri- gose hairs with a stellate, radiate, irregularly branched, or suprabasally expanded base, or hair types clearly modified from these conditions (6), petals with an apical apiculum on the abaxial sur- face (30), and a chromosome number of n — 28 (where known, 41). Kirkbridea likely is cladisti- cally basal in this group, with Henriettea, Hen- riettella, and Llewelynia being united by the ad- ditional synapomorphy of fasciculate inflorescences (13). (It should be noted that parallelism in flower size (17) occurs within these genera, which is not surprising considering the variability of this feature within the tribe. Linking Kirkbridea and Henriet- tella on the basis of this character is considered implausible.) The remaining taxa included in the analysis form a second clade based on the following synapomor- phies: presence of only druse crystals in leaf and stem tissues (4), small more or less sessile flowers (17, 14), and usually well-developed external calyx lobes (19). The extremely isolated genus Huilaea probably is basal within this clade (Fig. 1A, B) because it shows only the synapomorphy of exclu- sive presence of druse crystals (4), having large and clearly pedicellate flowers. The relationships among the taxa comprising this clade are not well resolved. However, it is clear that Maieta, Cli- demia sect. Calophysoides, and C. juruensis form — FIGURE 1. flowered taxa, 48 steps, consistency index — 0.813. analyses of taxa containing only druse crystals —two 26-ste nalysis.

Annals of the Missouri Botanical Garden a monophyletic group based on the presence of morphologically very similar pouchlike ant-domatia (formicaria) at the base of the leaf blade (10) and wrinkled anthers (36). In addition, Maieta and Clidemia sect. Calophysoides have anisophyllous leaves (9). If the character of 4-merous flowers is stressed, then Mecranium is probably most closely related to Clidemia sect. Sagraea, and the two may be linked by this feature (15). Linking Killipia with Sagraea and Mecranium in some trees on the basis of the shared loss of strigose hairs (5) probably has little phylogenetic significance. The terminal-flowered taxa of Miconieae may be a paraphyletic or monophyletic group basal to all the axillary-flowered taxa (Fig. 2A-C) or a pos- sible sister taxon to the taxa containing only druses (Fig. 2D). In the first alternative, the axillary- flowered condition evolved just once and serves as a synapomorphy of all axillary-flowered Miconieae; in the second, axillary arrangements are hypoth- esized to have evolved in the druse and megastyloid clades independently (or, less likely, evolved in the stem lineage of the entire tribe with a reversal to terminal cymes occurring in the ancestor of Mi- conia and relatives). The possible polyphyly of the axillary-flowered Miconieae clade will be investi- gated more thoroughly in a later paper. It is cer- tainly possible that Miconia and relatives are more closely related to the axillary-flowered ““druse-con- taining" genera than initially hypothesized. When an EU representing a generalized ter- minal-flowered taxon is included in the analysis, the position of Huilaea in the cladograms becomes more variable than in the initial analyses (compare Figs. 1 and 2). This variability may reflect the presumed phylogenetic isolation of this genus. It seems more reasonable to link Huilaea with Mecranium, Clidemia sect. Sagraea, Maieta, and Killipia on the basis of the presence of only druse crystals in its tissues (4) than with Loreya, Hen- riettea, and Kirkbridea on the basis of a reversal to pedicellate flowers (14) (Fig. 2). he presence of both terminal and axillary flow- ers in Clidemia sect. Miconiopsis (Cogniaux, 1888, 1891) is not surprising (see Judd, 1986a, for dis- cussion of similar variation evident in Miconia, especially in sects. Octomeris (Naudin) Benth. & Hook. and Tamonea; and Troll, 1964, and We- berling, 1965, 1988, for more general discussion of inflorescence structure and position). Wurdack's suggestion (pers. comm.) that this group is closest to Miconia is likely correct. Note especially the similarity in stellate indumentum (8; Fig. 4) and circumscissilly dehiscent calyx (23). The section may be quite close to Miconia sects. Tamonea and Jucunda. The linking of Clidemia sect. Miconiop- sis with. Killipia or a clade containing Killipia, Clidemia sect. Sagraea, and Miconia in the cla- distic analysis probably is due to homoplasy in several fairly weak characters, e.g., loss of strigose hairs (5), or to several potential synapomorphies between the axillary-flowered taxa containing only druse crystals and Miconia (and relatives), e.g., more or less sessile flowers (14) or well-developed external calyx lobes (19). In spite of the necessarily preliminary nature of these cladistic analyses, their results help determine the previously confused generic limits within this difficult tribe (see also Judd, 1986a, b). In inter- preting these results, I have attempted to delimit monophyletic and phylogenetically equivalent gen- era within the tribe that are recognizable on the basis of several morphological characters. Thus Huilaea, Mecranium (including Ekmaniocharis and Ossaea acuminata), Killipia, Maieta (in- cluding Clidemia sect. Calophysoides and C. ju- ruensis), Loreya (including Bellucia and Myri- aspora), Henriettea (including Henriettella and Llewelynia), and Kirkbridea are considered to be generically distinct. In addition, Clidemia sect. Sagraea (including Necramium and the species of Ossaea with axillary 4-merous flowers) is recog- nized at the generic level. Finally, the species of Ossaea with axillary 5- (or 6-)merous flowers are in need of generic recognition and are described herein as Pentossaea. The systematics of each of these taxa is discussed briefly below. Discussion of axillary-flowered genera. Loreya is clearly delimited by its distinctive usually robust fleshy anthers (34), expanded and radiately ridged stigma (38), lack of external calyx lobes (20), and range of chromosome numbers (42, see Solt & Wurdack, 1980). The group possesses me- gastyloids in its leaf and stem tissues (pers. obs.; Baas, 1981) and is clearly monophyletic. However, if Bellucia and Myriaspora are segregated as sep- arate genera, the result is a paraphyletic Loreya (Fig. 1). Bellucia is characterized by papillose abaxial leaf cuticle (11), closed buds (24), i.e., the buds have thick calyx lobes that cover the buds up to the final stage prior to anthesis (and are even fused into a cap in a few species, e.g., Bellucia dichotoma Cogn. and B. acutata Pilger), and ten- dency for floral merosities greater than five (16) (see Renner, in press). In contrast, Myriaspora is characterized by its highly divided placentae (39), calyx lobes fused into an unusual cap (26, which is probably not homologous with the cap of some species of Bellucia), and long hairs on the abaxial Volume 76, Number 2 1989 Judd Miconieae 485 surface of its petals. In addition, Myriaspora pro- duces inflorescences in the leaf axils (as do several species of Bellucia), while the usual condition in Loreya is to have the inflorescences lateral on leafless nodes below the leaves; it should be noted, however, that this character is often variable within a genus (Judd, 1986a; Renner, in press). No autapomorphies are evident for Loreya when certain species are segregated as either Bellucia or Myriaspora (Fig. 1). The paraphyly of Loreya is made even more apparent when it is realized that Loreya subrotundifolia (Wurdack) S. Renner and L. riparia S. Renner link with Bellucia on the basis of higher numbers of floral parts and that L. mespiloides Miq., L. spruceana Benth. ex Triana, and L. klugii S. Renner link with Myrias- pora on the basis of testa characters and one- pored anthers (Renner, in press). hus, recognition of Bellucia and Myriaspora distorts the best estimate of phylogenetic structure currently available for this group of species. Their recognition is also doubtful on purely phenetic grounds, since the patristic distances separating Bellucia and Myriaspora from the cladistically related taxa within a narrowly delimited Loreya are comparable to those separating other clades within Loreya (Renner, in press). Thus, as is char- acteristic of traditional taxonomic procedure (see Stevens, 1984, 1986), recognition of Bellucia and Myriaspora can only be justified by selective weighting of certain features (in this case the char- acters of cuticular papillae, bud structure, placental form, and inflorescence position) due to their sup- posed greater ecological significance. I see no rea- son to weight these characters more than any oth- ers used in these analyses. The decision to recognize a broadly circumscribed Loreya is not new; Baillon (1877) also considered Bellucia and Loreya con- generic (although only few species were known to him), and Macbride (1941: 497) considered this . to 'straining at treatment “‘preferable it seems . . a gnat’ to keep them apart.” Gleason (1932) con- sidered the genera only “weakly separated"; how- ever, they were maintained as distinct by Wurdack (1973, 1980) and Renner (in press). Henriettea is easily recognized by its usually expanded, radiate to globular-stellate basal portion (or easily derived types, such as stellate-hairs, pel- tate-scales, elongate hairs with numerous small mainly basal projections, elongate hairs with a su- prabasal expanded region and a narrowed basal attachment, or hairs very reduced, e.g., Henriet- tella caudata (DC.) Naudin, H. glabra Cogn.; see Wurdack, 1986) (6), petals with a minute dorso- apical apiculum (30), and chromosome number of n — 28 (41, Solt € Wurdack, 1980). Fasciculate inflorescences have evolved independently in a few species of Loreya (Renner, in press), and the in- florescences of Henriettea squamulosa (Cogn.) W. Judd have reverted to a pedunculate condition (Judd, 1986b). Henriettea is clearly monophyletic and shows the presence of calcium oxalate megastyloids (similar in structure to those of Loreya) in its leaf and stem tissues (pers. obs.; see also Welle & Mennega, 1977; Welle & Koek-Noorman, 1981; Baas, 1981). As with Loreya, problems of paraphyly occur when Llewelynia and Henriettella are recognized as distinct from Henriettea (Fig. 1). Llewelynia is phenetically distinctive (Pittier, 1939; Wurdack, 1973) and easily recognized by its loss of external calyx lobes (20), open calyx cap that opens by a circumscissile slit (27, 28), and numerous stamens (37), while Henriettella is only marginally sepa- rable due to its smaller flowers (17) and tendency to have shorter anthers that open by larger, gaping pores (see Wurdack, 1973, 1980). A nearly ob- solete internal calyx has evolved in a few species of Henriettella, e.g., H. sessilifolia (L.) Triana, and in many species the internal calyx lobes are not well developed. Henriettea and Henriettella were considered congeneric by Macbride (1941: 500), who stated that "there seems to be no sig- nificant concomitance of the characters of petals, anthers or pubescence that have been used to main- tain two similar but distinct genera.” He added that “the characters moreover often exist in de- grees of development.” Richard A. Howard also will consider Henriettea and Henriettella to be congeneric in his Lesser Antilles flora (pers. comm.). Wurdack (1972: 418) maintained these genera but noted that “a generic transition zone exists between Henriettella ovata Cogn. and Henriettea patrisiana DC., with Henriettella parviflora (Griseb.) Triana perhaps not distinct from the lat- ter.” The genera differ in flower size, anther char- acters, and indumentum, but intermediates exist. Not surprisingly, there are no autapomorphies for Henriettea when defined narrowly, and its species certainly intergrade with Henriettella. The floral buds of some other species of Hen- riettea (e.g., H. spruceana Cogn., H. succosa (Aublet) DC.. H. stellaris Berg ex Triana, and H. ramiflora (Sw.) DC.) possess an expanded and open cap formed by the inner calyx lobes very similar to (and likely homologous with) that of Llewelynia, although opening longitudinally rather than cir- Annals of the Missouri Botanical Garden cumscissilly. These species are likely basal mem- bers of the clade leading to Llewelynia. It is of interest that Wurdack (1973) suggested a similar- ity in general facies between Llewelynia and Hen- riettella, and Welle & Koek-Noorman (1981) re- ported similarity in wood anatomical characters between Llewelynia and Henriettella. It thus seems best to recognize a broadly defined, and monophy- letic Henriettea by including both Henriettella and Llewelynia within it. Kirkbridea clearly is related closely to Hen- riettea s.l. (Fig. 1). Kirkbridea (Wurdack, 1976) is quite distinctive due to its pedunculate inflores- cences and anthers with two well-developed dorso- basal projections (33). Kirkbridea and Henriettea show variation in number of floral parts. Huilaea is evidently very isolated, as Wurdack (1957, 1976) suggested at the time of his descrip- tion of the genus. It clearly is distinct generically and is recognizable due to its pendent, three-flow- ered cymose inflorescences with very long pedun- cles and large, clearly pedicellate, 6-merous flow- ers. Maieta, defined broadly, is a monophyletic group best recognized by its characteristic pouchlike for- micaria at the base of its leaf blades (10) (Fig. 3; see discussion of morphology, development, and ecological functions of these structures in Gleason, 1931; Schnell, 1967; Whiffin, 1972; Neto € Asakawa, 1978; Benson, 1985). It should be noted that ant-domatia of various types undoubtedly have evolved independently in a few to many species of several other genera (e.g., Sagraea DC., Tococa, Clidemia, Henriettea, and Conostegia D. Don), and additional developmental studies are necessary in order to determine appropriate homologies of such structures within the tribe. The presence of structurally and positionally very similar pouchlike ant-domatia is accepted as a provisional synapo- morphy of Maieta s. od me Cudenia sect. t ophysoides until s are conducted. The group alo tends to Hadas e ly wrinkled anthers (36) and clearly anisophyllous leaves (9). Druses are the only crystals known in this group. The species of Maieta (defined nar- rowly—see Aublet, 1775; Wurdack, 1980) have sagittate anthers (35) and show a reversal toward large flowers (17), while those of Clidemia sect. Calophysoides have a distinctly ribbed hypan- thium (18). Both, along with possibly a few other species of Clidemia, such as C. juruensis, are considered congeneric. The close relationship be- tween these species of Clidemia with pouchlike formicaria and the phenetically similar species of Maieta has long been recognized. Macbride (1941: 479) remarked that “Clidemia remains . . . a con- cept rather arbitrarily retained but conveniently so on account of Maieta (in which Baillon, Hist. Pl. 7: 56. 1880 rightly merged it) being the older name." I agree and here consider Maieta to be congeneric with Clidemia sect. Calophysoides (and C. juruensis). Killipia (Fig. 4) is a distinctive genus not easily confused with any other in the complex of genera possessing only druse crystals. Noteworthy apo- morphies are the very long internal calyx lobes with closely associated external calyx lobes (21) and distinctive anthers with two dorso-basal pro- jections (33); see description of genus in Gleason (1925). The stems of Killipia quadrangularis are quadrangular and ridged-winged (1); however, two other species have terete stems. The abaxial leaf surface of K. quadrangularis is usually red, an apomorphy not included in the analysis, which has also evolved within several genera with terminal inflorescences. The cladistic relationships of Kil- lipia are obscure, although it is closest to Maieta, Mecranium, Sagraea, and Pentossaea (Fig. 1). The species formerly of Ossaea with axillary 5-merous or occasionally 6-merous flowers warrant generic recognition (Fig. 5). The petals of this group are narrowly triangular with an acute apex (29), and the group is clearly separable from related taxa (see key). It is not surprising that a group of Ossaea species was found to be in need of generic recognition, since the genus has long been sus- pected of being polyphyletic (see Judd, 1986a). Wurdack (1962: 206), for example, stated that "the genus is an artificial assemblage of various species groups." The distinctive clade, with axillary 5-(6-)merous flowers, is here described as the genus Pentossaea. Pentossaea W. Judd, gen. nov.

Melastoma marginata Desr. in Lam., Encycl. 4: 32. 1797 Additional new combinations will certainly be- come necessary following a detailed revision of the genus. The axillary-flowered 4-merous species of Os- saea and the very similar species traditionally placed in Clidemia sect. Sagraea (also axillary-flowered and 4-merous; see Cogniaux, 1891) are typically separated by the technical character of apically acute vs. blunt petals. However, I found this char- acter to vary continuously within the group, and several species placed in Clidemia sect. Sagraea actually have acuminate or acute petals (e.g., C. oligantha Urban, C. fuertesii Cogn., C. domin- gensis (DC.) Cogn., C. crossosepala Griseb.), while others treated in Ossaea may have blunt-tipped petals (e.g., O. barahonensis Urban & E. Ekman or O. setulosa Urban). Some taxa have been con- sidered members of both groups by various authors. In addition, phenetically very similar species have sometimes been placed in the two "genera," e.g., Clidemia crossosepala and Ossaea hirtella (Sw.) Triana (see Adams, 1972), and petal shape and apex occasionally vary infraspecifically, as in Cli- demia fuertesii. Thus, all 4-merous, axillary-flow- ered members of the ““druse-containing group” (Fig. 2) with free internal calyx lobes, no androecial fringe, and a usually well-developed strigose in- dumentum are placed together in Sagraea (Fig. 6; also see key) Necramium (Britton, 1924), 4-merous axillary flowers having ovate, sharply acuminate petals and with an indumentum of long strigose hairs and irregularly branched-stellate hairs, clearly also belongs to this clade. A close association between Necramium and some species of Ossaea was recognized by Wurdack (1973: 721-722), who stated that Necramium was "realmente bien acomodado dentro de Ossaea DC. sensu Cogniaux pero la necesidad por una transferencia posterior a genus with cuando ese conjunto artificial se disperse se opone a la sinonimización inmediata." Wurdack (pers. comm.) suggested affinity of Necramium to Ossaea sect. Octopleura (Griseb.) Cogn. This is judged unlikely, however, since the latter group has ter- minal inflorescences (although frequently deflexed to a seemingly lateral position, see Judd, 19864), a glandular dorso-basal connective appendage, and strongly costate fruits. Necramium (Britton, 1924) is not the oldest name available for this clade, the names Ossaea and Sagraea (de Candolle, 1828) both having priority. Because the types of Sagraea (S. cap- illaris (Sw.) DC., here designated) and Ossaea (O. scalpta (Vent.) DC., here designated) fall within the group circumscribed above, and the two genera were described at the same time (de Candolle, 1828), either name is available for this group. The name Sagraea is chosen here, since I wish to avoid the use of Ossaea, a name that has been used for a great many discordant species-groups (see Wur- dack, 1962, 1973, and Judd, 1986a). It is note- worthy that Triana (1871) considered these axil- lary-flowered species (along with a few discordant elements) to be generically separable (as Sagraea) from the terminal-flowered Clidemia. Sagraea may be most closely related to Mecra- nium, a more specialized genus also showing 4-merous flowers, this a potential synapomorphy (15, Figs. 1, 2). Sagraea is considered to be meta- phyletic (Donoghue, 1985; Mishler, 1985; Mishler & Brandon, 1987) because its ca. 60 species show no autapomorphies in some of the generated clado- Judd Volume 76, Number 2 1989 Miconieae A Zh LFH A E [L4 vy PEO ty, Sod e t E 470 A TR , aa La - Ss, at stg faz MM CMM 4 fa TLE $ di ue LL’ LET hdl N KS SS 4 Es ASS FIGURE 6.

However, in other equally parsimonious rather variable group is considered appropriate and trees, the group appears monophyletic, being de- fined by a reversal to strigose hairs (5) or by a parallel evolution of 4-merous flowers (15). The group is possibly paraphyletic, but no character conclusively demonstrating this has been deter- preferable to leaving its species in several artifi- cially delimited genera. Several species of Sagraea have evolved for- micaria at the base of the petiole, e.g., Clidemia 492 Annals of the Missouri Botanical Garden C iEZII I Mz FIGURE 7. Mecranium multiflorum (Desr.)

Plants with a climbing habit and strongly anisophyllous leaves occur in Clidemia epiphytica (Triana) Cogn., a species that is also cytogenetically distinctive (Solt & Wurdack, 1980). As discussed above, anisophyllous leaves are char- Volume 76, Number 2 1989 Judd 493 Miconieae acteristic of Maieta, and this feature undoubtedly has evolved in parallel in the two genera. It is not considered appropriate to make the many necessary new combinations in Sagraea until a thorough taxonomic revision of the genus has been completed.

Mecranium (Fig. 7) is a distinctive monophyletic species group distinguished from other genera con- KEY TO AXILLARY-FLOWERED MICONIEAE taining druse crystals by its internal calyx lobes fused into a domelike, apiculate, and membranous cap that is ruptured irregularly by elongation of the style and emergence of the petals at anthesis (22), the external calyx lobes reduced in length and often inconspicuous (reversal of 19), androecial fringe (i.e., a ring of erose to ciliate appendages arising from apex of hypanthium [torus] internal to the stamens [32 )), and usually sparse and poorly developed indumentum (7); see Judd (19862) and Skean & Judd (1986). Because these apomorphic characters are found also in the monotypic Ek- maniocharis (E. crassinervis; Urban, 1921; Judd, 1986a; Skean, in press), it is clear that this genus belongs in Mecranium. Likewise, Ossaea acumi- nata (Judd, 1986a) shows all these apomorphies except that of a domelike, apiculate cap. In this species the apices of the internal calyx lobes are distinct and imbricate, although the lobes are con- nate for most of their length, forming a structure that may be similar to the condition from which an apiculate cap was derived. It is obvious that O. acuminata is a basal member of the Mecranium clade. The nomenclatural transfers will be made by James D. Skean, Jr. in a monographic study of Mecranium currently near completion. A more detailed analysis of the phylogeny of this genus will be presented by Skean (in prep.) n summary, the phylogenetic relationships (and taxonomic diversity) among the axillary-flowered Miconieae are most clearly represented by a taxo- nomic system recognizing the following nine genera as delimited above: Henriettea, Huilaea, Killipia, Kirkbridea, Loreya, Maieta, Mecranium, Pen- tossaea, and Sagraea. la.

REPRODUCTIVE BIOLOGY IN NEOTROPICAL MELASTOMATACEAE AND MEMECYLACEAE! ABSTRACT In the Neotropics, the arena and de e comprise over 3,000 species in 106 genera. Pollination observations have been reporte 26 species in 35 genera of Melastomataceae and for four species in one genus of Memecylac ceae. Genetic llinc bo, has been found in 22 Melastomataceae species, self-compatibility in 25 species. A s ingle m e e tested i is self- -compatible. Agamospermy is known in 19 New World and ace is known in a few species in one genus of Melastomataceae. The principal mode of promoting outcrossing in both families is spatial separation of pollen and stigma (herkogamy), achieved by the pollen being enclosed in poricidal anthers, which have to be manipulated to release pollen. New World Memecylaceae are pollinated in the same way and by some of the same bee species as most Melastomataceae. All bee species known to visit Melastomataceae and Meise :ylaceae are list ed; they comprise a ius seda of the a bee fauna. It is not yet c wouie in the ee mec ia beyond that ife en nhan cing the visual attractiveness of the eni and making ihe stamens easier to grasp. In most Melastomataceae, flowers offer only pollen; however, some 60 species in 8 gene r nectar as a reward for pollinators (probably, some species in at least one additional genus do, too). The nec dea species are pollinated by birds, bats, rodents, and bees. e nectar is rich in sucrose and, as a rule, its production is correlated with floral morphological changes relating to the fact that, except for bees, nectar consumers do not vibrate the stamens to collect pollen actively.

I conclude that the east and west Gondwanian lineages of Melastomataceae and emecylaceae, i a coevolved he earliest bees in the lo id- Cretaceous. This may have been the time when the ancestors of these families switched from nectar-reward flowers to pollen-r reward flowers. In the further extensive radiation of jm families, special adaptations to pollinators were of limited importance; diversification in seed dispersal systems, vegetative characters, and edaphic adaptations were more important. The neotropical Melastomataceae and Meme- the field and the availability of several recent treat- cylaceae are particularly suitable for a study of ments in monographs and floras.

The Melastomataceae are a large family (v.i.) and diverse in terms of habit, reproductive and vege- tative architecture (Cremers, 1983), and indument (Wurdack, 1986). Memecylaceae comprise about 89 species in the Neotropics and are much less diverse in these characters. The present survey is based on my observations of the reproductive biology of many Brazilian and some Venezuelan species and on a review of the literature. The survey is presented in five sections. First, an outline of the classification and repro- ductive morphological features of the Melastoma- taceae and Memecylaceae is given; second, breed- ing systems and cytology are discussed; third, the pollination spectra found in the two families are described; fourth, a brief survey is made of seed dispersal in the two families; fifth, the reproductive biological information is related to the fossil record and distributional data to contribute to a better understanding of the historical evolution of the two families. Flowering and fruiting phenology of neotropical melastomes and Memecylaceae are not dealt with here, but reference ma made to Snow (1965), Croat (1978), Opler et al. (1980), Hilty (1980), Lumer (1982), and Renner (1984 and in prep.). Suffice it to say that synchronous, episodic flow- ering with the episodes of short duration (a few days) characterizes some of the arborescent species of the largest genus, Miconia, whereas extended flowering periods (several weeks or months) are characteristic of many of the shrubs, herbs, epi- phytes, and some of the tree species. CLASSIFICATION AND REPRODUCTIVE MORPHOLOGICAL FEATURES Worldwide, the Melastomataceae A. L. Juss. (excluding the ca. ten species of Crypteronia, Ax- inandra, and Dactylocladus, i.e., the Crypteronia- ceae; Dahlgren & Thorne, 1984) and the Me- mecylaceae DC. consist of ca. 190 genera and approximately 4,800 species. In the Neotropics, the Melastomataceae comprise over 3,000 species in 107 genera (Table 1) and the Memecylaceae 89 species in two genera. About half of these genera contain only one to four species, whereas one ge- nus, Miconia, has some lastomataceae as a subfamily, it has been pointed out (see Morley, 1953; Dahlgren & Thorne, 1984; Johnson & Briggs, 1984) that the differences be- tween these families are such that their union ob- scures rather than reflects our knowledge of the two groups. The Memecylaceae consist of the Asian genera Memecylon (ca. 300 spp.) and Lijndenia (4 spp.) (Bremer, 1982, 1983), the African Spa- thandra (6 spp.) and Warneckea (31 spp.), and the neotropical Votomita (8 spp.; Morley, 1963) and Mouriri (81 spp.). There is a consensus that the Melastomataceae and Memecylaceae belong to the core families of the order Myrtales (Dahlgren & Thorne, 1984; Johnson & Briggs, 1984). The classification of the Melastomataceae sensu stricto is essentially that of Triana (1867), who was closely followed by Cogniaux (1891). Wurdack (1980) has realigned the New World tribes in a sequence generally resembling that of A. P. de Candolle (1828). The main dichotomy in the Me- lastomataceae is between the capsular-fruited and the berry-fruited genera. The genera are arranged into tribes on the basis of fruit and seed characters and the presence and position of connective ap- pendages (D. Don, 1823; Triana, 1867; Cogniaux, 1891; Gleason, 1929; comp. also Whiffin & Tomb, 1972) Most Melastomataceae are characterized by poricidal anthers, the connectives of which are frequently prolonged (however, species of Miconia sects. Chaenopleura and Chaenanthera have an- thers that open by 1-2 slits). They usually have a pronounced foliar venation consisting of the mid- vein and one to four pairs of subparallel longitudinal veins. Memecylaceae, on the other hand, mostly have pinnate venation; their anthers open by short slits or pores. In a reproductive biological context, the presence of an elliptic, concave gland on the dorsal side of the connective is a unique feature characterizing most Memecylaceae. Volume 76, Number 2 1989 Renner 499 Reproductive Biology in Melastomataceae & Memecylaceae The flowers in both families are actinomorphic or weakly to strongly zygomorphic as a result of movements of the stamens and style immediately after the expansion of the petals (Troll, 1922; Ziegler, 1925; pers. obs.). In Melastomataceae, the flowers are usually borne in well-developed cymose inflorescences, whereas in Memecylaceae the cymes are often condensed or reduced to a few flowers in fasciculate tufts. In both families, the mostly 4- or 5-merous flowers are perigynous or epigynous with a cup-shaped hypanthium that bears on its rim the calyx lobes, petals, and sta- mens. The antepetalous stamens are usually longer than the antesepalous ones, which may be stami- nodial; this dimorphism is more or less pronounced and has given occasion to much speculation con- cerning its role in pollination. In Melastomataceae with poricidal anthers, the anthers are one- or two- pored, a character that is consistent at the species level but varies within genera; there is also con- siderable variation in the size and position of the pores. Pollen grains are usually free, small, and rather smooth, although polyads and tetrads are known in species of Tococa and Miconia (Patel et al., 1984). BREEDING SYSTEMS The principal mode of promoting outcrossing in most Melastomataceae and Memecylaceae is the very effective spatial separation of pollen and stig- ma in the flowers (herkogamy). This is achieved by the pollen being enclosed in tubular anthers with apical or subapical pores or slits, which are gen- erally minute, and positioned well distant from the punctiform or capitate stigmas. Also, the stamens are usually shorter than the styles. In bud, the stamens are always folded over in such a way that the anther pores point downward and are maxi- mally distant from the stigma, which lies at the tip of the bud. Thus, chances for automatic selfing before and during anthesis are very low or nil. If, however, during anthesis, an anther or the style bends in such a way that the pore is brought into contact with the stigma, automatic selfing may occur. This has been reported for Monolena trichopoda (Melastomataceae; Warner, 1981) where, late in anthesis, the stamens fold over and the thecae are effectively stuck to the stigmatic exudate. No pollen escapes from the anthers unless me- diated by a vector, which at least potentially may arrive bearing conspecific pollen. Almeda (1977, 1978) suggested that vigorous mechanical move- ment of the anthers by gusty winds or rains might release pollen in species of Monochaetum and Cen- tradenia (Melastomataceae). Additionally, he often observed pollen in water droplets connecting an- thers and stigma and suggested that this might be another possible route for selfing to occur. How- ever, bees, which regularly collect pollen from Me- lastomataceae, use vibrations of around 420 Hz or higher (this frequency was found to effect ample pollen emission from the large anthers of Bellucia; see below). Therefore, it seems unlikely that the low-frequency vibrations produced by wind could release pollen This impression is supported by the lack of fruit set in bagged flowers of nonagamospermic species ex- posed to strong wind (Renner, 1984). While autog- amy may be extremely rare, vector-mediated self- ing (i.e., geitonogamy), a function of pollinator behavior and number of conspecific flowers avail- able at a time, may be frequent in self-compatible rom melastome anthers. species. Temporal separation of male and female func- tion has been suggested for species of Monochae- tum (Almeda, 1978) in which *'the ill-defined stig- matic region . . . appears to be non-receptive during the first day." This may be a rare condition be- cause, as a rule, poricidal flowers that offer only pollen as a reward (subsequently also called “‘pol- len-only flowers”) receive foreign pollen at the same time a visitor harvests pollen from them; in female- phase flowers, there is nothing to reward visitors (only mimicry or deception might account for visits to female-phase flowers). Homogamy, i.e., the si- multaneous functioning of the male and female parts, is thus to be expected in pollen-only flowers. Temporal separation of the male and female func- tion in single flowers has been reported twice in nectariferous melastomes (Ule, 1896; Vogel, 1957); in both cases, the flowers were protandrous. The Melastomataceae are not entirely her- maphroditic. Wurdack (1964) was the first to de- scribe dioecism in Miconia dioica Wurdack; her- barium specimens of this species had female flowers with abortive stamens and male flowers with poorly developed stigmas. He also suspected dioecism in some other minute-flowered Andean species of Mi- conia (M. dielsii Markgraf, M. clathrantha Tr. ex Cogn., M. minuta Gleason; Wurdack, 1980: 261-262) and in M. rubens (Sw.) Naudin from the West Indies and Venezuela (Wurdack, 1964). Field observations on the reproductive biology of these and some other suspected dioecious mela- stomes are lacking. At least one species of Lijndenia (Memecyla- 500 Annals of the Missouri Botanical Garden ceae) has hermaphrodite-flowered individuals and purely male-flowered ones (Bremen, 1982). GENETIC COMPATIBILITY As shown in Table Z, genetic self-incompatibility occurs in at least 22 species in the two families. As Darwin remarked (in a letter to J. D. Hooker on Nov. 28, 1871, in F. Darwin (ed.), 1903), melastomes *'are troublesome beasts to fertilise.” This is due to the closed anthers and mostly punc- tiform stigmas. In some large-flowered species, such as Bellucia (Melastomataceae), it is possible to collect large amounts of pollen for experimental purposes by holding a tuning fork to the stamens. Self-compatibility is found in 26 species (Table 2). Since no efforts have ever been made to distinguish pseudogamy from self-compatibility, several of the supposedly self-compatible species reported earlier (Darwin, 1876; Ziegler, 1925) may have set fruit as a result of agamospermy rather than of self- fertilization. Related species such as Tococa guia- nensis and T. bullifera or Centradenia grandi- flora and C. paradoxa (all Melastomataceae) differ O in their compatibility conditions (Table 2). Th humid stigmatic surface and the binucleate pollen of the Melastomataceae and Memecylaceae (Tobe & Raven, 1984) indicate that the incompatibility system is gametophytic (Nettancourt, 1977) AGAMOSPERM Y Experimental proof of agamospermy in mela- stomes is readily obtained by cutting off the style in freshly opened unvisited flowers. (To ensure that flowers are unvisited before the style is cut off, they must be bagged the evening before.) Apart from the 22 apomictic Melastomataceae listed in able 3, polyembryony, with additional embryos baina formed by nucellus or suspensor cells, has been reported from the Asiatic species Osbeckia hispidissima Wight, Sonerila wallichii Benn., and Melastoma malabathricum L. (Subramanyam, 1942, 1944, 1948). Polyembryony is often cor- related with agamospermy (Gustafsson, 1946-47). Mouriri nervosa is the only member of the Me- mecylaceae so far tested for agamospermy, with negative results (Renner, unpubl.). In several of the neotropical species showing apomixis, for in- stance in Clidemia novemnervia and Macairea theresiae, the anthers contain very few pollen grains. In cultivated neotropical Leandra cordi- folia Cogn., Subramanyam (1942) also found that a low percentage of fertile pollen grains was com- bined with the frequent formation of two embryo sacs. In most neotropical species, agamospermy is correlated with low stainability of fresh pollen in cotton blue with lactophenol. This stain indicates presence of callose, a saccharide found in the intine of pollen. Lack of an intine could make a grain unviable and is usually accompanied by lack of cytoplasm. However, in Aciotis acuminifolia and Miconia argyrophylla, pollen grains stain heavily, yet these species are capable of producing seeds apomictically. In Clidemia and Maieta poeppigii, the stamens do not unflex com- novemnervia pletely upon anthesis but remain curved, and are thus not available for legitimate bee pollinators. Both species regularly set seeds apomictically. 82) observed that Blakea gracilis, Blakea sp. (originally identified as B. grandiflora), and Topobea brenesii ripened a large number of seedless fruits from emasculated flowers; however, in T. pittieri, she found that of the bagged flowers, 35% produced mature fruits containing seeds. Dar- win (1876) and Ziegler (1925) observed fruit set in cultivated plants of Monochaetum, Tibouchina, Centradenia, Calvoa, and Dissotis in the green- house. Assuming that there were no bee pollinators Lumer in the greenhouses, it is likely that such fruits resulted from agamospermy rather than from autogamy, which, as pointed out above, is me- chanically difficult in Melastomataceae. The number of species investigated is still too small to draw firm conclusions about correlations between habit, habitat, and breeding system. Of the agamospermous species, 13 are shrubs of var- ious types of savannas or of secondary vegetation; five are treelets, two are herbs, and one is a climber. The sample is clearly biased towards shrubby species, however, because of their accessibility. CYTOLOGY Some 300 of the over 3,000 species of neo- tropical Melastomataceae and only one species of Memecylaceae (Mouriri myrtilloides) are known cytologically (Solt & Wurdack, 1980). Only a few of these have been examined twice. Melastome chromosomes are very small (0.5-1 micron; Solt S Wurdack, 1980) and stain poorly. common base numbers are 9 and 17 (Wurdack & Kral, 1982). Based on Solt & Wurdack's results, the incidence of polyploidy in the Melastomataceae The most seems high. It cannot yet be answered whether polyploidy is more frequent in species with strong agamospermous reproduction than in those which lack apomixis, nor whether there is a correlation between polyploidy and growth habit.

Pollination by hummingbirds, bats, MELASTOMATACEAE POLLINATION BY POLLEN-COLLECTING BEES and rodents is found in an estimated 60 species of Meriania, Centronia, Brachyotum, Tibouchina, Miconia, Huilaea, Chalybea, and Blakea (Table 4), and probably also in Axinaea (see below). The mode of pollination is determined by the type of reward offered: Melastomataceae and Memec yla- ceae with pollen-only flowers are, as a rule, polli- nated exclusively by bees because the morphology of the anthers excludes all other pollen-collecting vectors. In contrast, the nectar-offering species attract a wide variety of pollinators. a) Methods of pollen collection and kinds of bees Pollination by bees has been reported for some 120 species in 31 genera of Melastomataceae (Ta- ble 4). In addition, a few species occurring at Finca La Selva, Costa Rica, and near Kourou, French Guiana, have been observed to be pollinated by small and medium-sized bees (Bawa et al. 1985; Roubik, 19792). Many unidentified melastomes are indicated as visited by bees in apidological studies (e.g., Sakagami et al., 1965, and Roubik, 1979b). TABLE 3. Agamospermous Melastomataceae.

Note that ascertained at present. excludes “halictids”” the numerous Trigona species, which are omnipresent pollen scavengers on stands for many different species, the correct names of which cannot be 508 Annals of the Missouri Botanical Garden Bees gathering pollen from Melastomataceae flow- ers must be able to shake it out of the anthers or else pull pollen grains out through the pores with their tongues. This latter mode of exploiting mela- stome flowers is used by a group of Trigona bees and does not usually result in pollination because these bees are too small to contact the stigmas. Another subgroup of Trigona bees, characterized by having toothed mandibles, cuts up melastome anthers and robs their pollen (Laroca, 1970; ner, . The method of pollen collecting used by all other bees to extract pollen from melastome anthers was first described correctly by van der Pijl (1954). When approaching a flower, in flight, the bees orient themselves with the group of stamens and the style and then straddle the stamens. They usu- ally grasp the filaments or the bases of the anthers, quite often using their mandibles. Therefore, after having been visited, flowers often show necrotic spots on the outside of the stamens where the bees held onto them. When the bees position themselves over the androecium, their potentially pollen-bear- ing surface contacts the stigma even before they start exploiting the anthers. Also, they strive to establish a firm contact with as many stamens as fT, their body size permits, going tc in order to bundle all 8, 10, or 12 stamens. Close contact between the bee and the stamens is nec- essary for pollen collection by means of thorax vibrations, which are transmitted to the stamens and cause the pollen to stream out of the anther pores. Electrostatic forces due to the net positive charge of the bees and the negative charge of pollen greatly aid pollen-load adhesion (Thorp, 1979). When a pollen load, taken with forceps from a freshly captured bee, is released near this bee, it jumps back onto it (pers. obs.). The very rapid distortions of the thorax-box (with the wings at rest) are made possible by the unique contractile prop- erties of the bees’ fibrillar indirect flight muscles. Pollen collecting by this method is always accom- panied by a characteristic buzzing sound and has Michener, 1962). The rapid vibrations used when harvesting mel- astome pollen presumably produce a high temper- ature of the flight muscles, this method of pollen collecting is particularly ap- been termed “‘buzzing method” (van der Pijl, 1954; ) which may mean that propriate during the relatively cool early morning hours. Also, there are ecological constraints on the activity of dark-colored bees during the hottest hours. Buzz pollination continues with very high humidity of the air and even during slight rains. In most melastomes, pollen deposition and re- ception is on the lower abdomen (sternotribic) or lateral on the bees (pleurotribic); it is on the back (nototribic) in a few species with downwards-curved styles (e.g., species of Meriania, Adelobotrys, Sal- pinga) and in Desmoscelis villosa. In these cases, bees assume quite unexpected positions in order to vibrate the stamens; in Adelobotrys rachidotricha, for instance, they buzz with the head pointing out- ward and downward. Relatively large flowers, such as those of Blakea, Topobea, and Bellucia, are by a ua range of bees (Lumer, 1982; Renner, 1986/1 87). For example, stamens of Bellucia are us by 33-mm-long Centris and 8-mm-long Augochloropsis bees. In the case of self-compatible species, visits by bees too small to contact the stigma and deposit foreign pollen may still result in self-pollen landing on the stigma when such small bees vibrate one or a few stamens. Bees visiting Melastomataceae exhibit consid- erable steadiness during individual foraging flights: pollen loads often consist of almost pure melastome pollen with very few grains from nectariferous flow- ers or with grains from Cassia mixed in (Renner, 984). Cassia has buzz-pollinated flowers, and bees often visit several such flowers (see below). In Brazilian Amazonia, | have captured 80 species of bees, including the Africanized honey bee, Apis mellifera scutellata Lepeletier, vibrating melastomes. (A list of all bees, including the species of Trigona, may be obtained upon request.) Ad- ditional species have been captured in extra-Am- azonian areas and at higher altitudes. To date, at least 100 species of bees have been found polli- nating melastome flowers (Table 4; this does not include the numerous species of pollen-scavenging Trigona bees). The relatively few groups of bees that have been successful in tropical forest envi- ronments, the euglossines, halictids, Xylocopa, and Melipona (Michener, 1979) tant pollinators of lowland melastomes. In savan- are the most impor- nas, Centridini, Oxaeidae, Exomalopsini, and Ptilo- a o glossa (Colletidae) become important, as bumblebees in southern Brazil and at higher alti- tudes. The bee fauna in neotropical forests and savannas is still incompletely known; however, based on bee inventories in Panama, Costa Rica, French Guiana, Surinam, and at the mouth of the Amazon (Heithaus, 1979; Roubik, 1979a, b; and ref. in Michener, 1979), it may be estimated that only about 300 species of bees occur in these forests, a number that includes non-flower-visiting parasitic and leaf-cutter bees. Thus, between 80 and 100 species collecting pollen from Melastomataceae represents a high proportion of the total Amazonian bee fauna Volume 76, Number 2 1989 Renner 509 Reproductive Biology in Melastomataceae & Memecylaceae b) Floral attractants Melastome pollen is an important pollen source for neotropical bees. This is clear from a survey of literature on bee foraging: it is collected by female euglossines (Moure, 1970; Janzen, 1971; Michener et al., 1978; Roubik, 1979a, b; Dressler, 1982; Renner, 1984), meliponines and halictids (Ducke, 1901, 1902; Laroca, 1970; Roubik, 1979a, b; Michener et al., 1978; Absy & Kerr, 1977; Absy et al., 1980), mixed with Malpighi- aceae oil by anthophorine bees (Vogel, 1974; Ren- ner, 1984), and makes up 96-100% of the nest provision of the colletid bee Crawfordapis (Roubik & Michener, 1985). A chemical analysis of Bel- lucia dichotoma pollen revealed high nitrogen and total crude protein. (I am indebted to S. Buchmann for analyzing a pollen sample in 1983.) In this species, the pollen has a strong perfume resembling that of the flowers. Secondary attractants for bees include sweet or perfumelike floral odors produced by the petals, the connective, and the upper section of the style (as determined by neutral red staining; pers. obs.; method, Vogel, 1963), and the presence of a land- ing platform provided by the androecium. I have never seen bees land on the petals. Frequently, the filaments are adorned with glandular or eglandular hairs, which may make them easier for the bees to grasp. Also, direct alighting on the stamens may make visits to flowers with poricidal anthers par- ticularly rewarding compared with flowers requir- ing further crawling and searching after landing. Most Melastomataceae seem to be visited and pollinated early in the morning, sometimes 20 min- utes before sunrise (F. Mueller, 1873; Frankie, 1976; Lumer, 1982; Renner, 1984), and many species close their petals by late morning. However, flowers of Monochaetum and Rhynchanthera open late, two to four hours after sunrise (Almeda, 1978; pers. obs.). Shedding of the flower parts usually starts at the end of the second day. Again, Mono- chaetum differs in having flowers that stay open for three days (Almeda, 1978), and I have seen Graffenrieda fruticosa flowers staying attractive for at least seven days. In the latter case, the adverse climatic conditions at 2,200 m altitude, where Graffenrieda fruticosa occurs, may place a high selective advantage on longer flowering pe- riods which presumably heighten the flowers' chances of being visited. The typical bee colors of most Melastomataceae flowers, white, purple, or pink, are due to total reflection and anthocyanins (Lowry, 1976; Bobbio et al., 1985). Yellow and orange flowers evolved repeatedly in isolated species throughout the fam- ily. Contrasting marks at the base of the petals and color changes during anthesis are frequent in Melastomataceae (F. Mueller, 1873; Ule, 1896; Wurdack, 1980; Renner, 1984). The colors change from white to red, from yellow to red, from white to purple, or from pink to white. The bright white of the small flowers of many herbaceous understory melastomes, e.g., species of Aciotis, Leandra, Cli- demia, Miconia, and Ossaea, may be of selective advantage under conditions of low light intensity. Some melastome flowers tested (using a Kodak 18 Wratten filter) did not absorb ultraviolet light (Lu- mer, 1982), as was to be expected from the absence of flavonols from their petals. The androecia of many species in the capsular- fruited tribes Merianieae, Bertolonieae, Micro- licieae, Tibouchineae, and Rhexieae show a strong morphological differentiation into two sets of sta- mens. In addition, in such flowers the connective appendages may be large and stiff, forming 5, 10, or 15 usually yellow spurs, sometimes positioned like true anthers. Based on his brother's (Fritz Mueller) observations on a southern Brazilian species of ** Heeria," Hermann Mueller (1881, 1883) was the first to suggest that this dimorphism was the ultimate result of a **division of labor" between the two sets of stamens (his illustration shows that his brother was probably dealing with a species of Microlicia; Heeria is synonymous with Hetero- centron, which does not occur in southern Brazil). According to this idea, the conspicuous anthers attract the bees and offer “food pollen” as a re- ward, whereas the less conspicuous ones contain “functional pollen." The “functional pollen" is sup- posed to be placed on a part of the bee where it will not be groomed off and used as food for larvae. It will instead function in fertilization. Hermann Mueller’s idea caught on immediately (Forbes, 1882; F. Mueller, 1883) and is usually mentioned as typical of the pollination strategy of Melasto- mataceae (e.g., Cammerloher, 1931; Percival, 1965; Kugler, 1970; Proctor & Yeo, 1972; Ba- ker, 1978; Faegri & van der Pijl, 1979). A partitioning of the bee surface would be nec- essary for selection to favor the pollen grains from one set of stamens over those from the other and thus lead to pollen dimorphism. Pollination mech- anisms involving vibration of anthers, however, may not allow a sufficiently precise placement of pollen from two sets of stamens on bees. Forbes (1882), working with unnamed species of Mela- stoma, reported that “only the pollen from the long stamens seemed [sic] to be fertile"; yet he found pollen from both types of stamens on the stigmas. To date, with the exception of Forbes's report 510 Annals of the Missouri Botanical Garden (1882), no morphological or physiological differ- ences between pollen grains from dimorphic sta- mens have been found in any of the Melastoma- taceae studied (Darwin, 1876; Ziegler, 1925; Whiffin, 1973; Almeda, 1977; Renner, 1984). Further experimental fieldwork is needed to assess whether the staminal dimorphism and the stamen appendages have a function beyond that of en- hancing the visual attractiveness of the flowers and making the stamens easier to grasp for bees. In view of the importance of pollen aromas for guiding bee behavior (cf. Dobson, 1987), it is uncertain if the visual cues provided by the yellow connective appendages by themselves elicit pollen-collecting behavior POLLINATION OF NECTAR-PRODUCING MELASTOMATACEAE BY BIRDS, BATS, RODENTS, AND BEES Some 60 species of Meriania, Centronia, Brachyotum, Tibouchina, Miconia, Huilaea, Chalybea, and Blakea, all of them, except the species of Miconia, occurring at higher altitudes (1,600-3,400 m), offer nectar as a reward for their pollinators. On the basis of their character syndrome (see below), Meriania drakei (Cogn.) Wurd., M. furvanthera Wurd., and several other species of Meri- Centronia, and Tibouchina are Axinaea weber- baueri Cogn., ania, Áxinaea, expected to produce nectar, too. he first reports on nectar production in mel- astomes are by Ule (1895, 1896). In three species of Tibouchina (Table 4) growing on the Brazilian Itatiaia mountain range, he observed that nectar was produced by the staminal vascular bundle and secreted either directly from the filaments or some- times through a slit in the filaments. He suggested bumblebees as the probable pollinators of these species. At Ule's request, the chemist T. Peckolt analyzed the stamens of another species that did not secrete nectar (Ule gave the name as 7. glare- osa Cogn.; there is no such name, and he probably meant 7° granulosa Cogn.). Peckolt found that ugar was present “in great quantity," which sug- eed to Ule (1896) that this was likely true for other species of Tibouchina as well. In several Pry other nectariferous melastomes, slits in the upper ventral side of the filaments have been observed, e.g., in Tibouchina cleistoflora Ule (Ule, 1896; pers. obs.), T. grossa, Blakea chlorantha (Tobe et al., in prep.), Brachyotum ledifolium, B. an- dreanum Cogn., B. benthamianum Triana, and B. rugosum Wurd. (Lagerheim, 1899; pers. obs.). They have also been found in non-aectariferous species— such as Centradenia grandiflora, Het- erocentrum roseum, Triolena pustulata (as Ber- tolonia pubescens) —and in paleotropical species of Dissotis and Medinilla (Ziegler, 1925). These slits appear not to be consistently formed sutures, but rather spontaneous ruptures. The anatomy of the nectariferous tissue is being studied by Tobe et al.

In central Amazonia, where I have observed this species, it did not pro- duce nectar (Renner, 1984).

Miconia robinson- iana, also with minute white flowers, was included under "nectar sources" records for Xylocopa darwinii by Linsley et al. 1966). McMullen, who made further observations on the floral visits of this bee on Galápagos (McMullen, 1985), has never noticed any nectar in M. comm., 1987) Except in Miconia, nectar production in Me- lastomataceae is correlated with floral morpholog- ical changes that relate to the fact that the nectar 'Therefore, in a summary of flower ~ robinsoniana (McMullen, pers. collectors do not vibrate the stamens. when nectar instead of pollen is the pollinator re- ward, the latter must be deposited on a visitor during nectar uptake.

The other nectariferous melastomes are reported as scentless. Volume 76, Number 2 1989 Renner 511 Reproductive Biology in Melastomataceae & Memecylaceae The bulk of nectariferous melastomes seem hummingbird-pollinated (Table 4). Most of them belong to the genus Brachyotum, which comprises 50 species, the majority ornithophilous (Wurdack, 1965, 1980; Lagerheim, 1899; Vogel, 1957; Fitz- patrick et al., 1979; label data). Other bird-polli- nated species are Meriania tomentosa (Cogn.) Wurd. (Centronia excelsa (Bonpl.) DC.; van der Werff, pers. comm.; D. Nei tariferous and hummingbird-pollinated species in the Miconieae are Huilea macrocarpa, H. pen- duliflora (Snow & Snow, 1980) and probably also Chalybea corymbifera (in which Stein observed nectar but no pollination events; pers. comm., 1987). The Colombian Tibouchina grossa is pol- linated by bats and hummingbirds (Vogel, 1957; Stein, pers. comm., 1987) and certainly the same is true of T. Stricta Wurd. and T. reticulata Cogn. New World rats and mice of the tribes Pero- mycini and Oryzomini pollinate at least three nec- tariferous species of Blakea in Costa Rica (Lumer, 1980, 1982; Lumer & Schoer, 1986). Lumer found that bees and hummingbirds rarely visited the flowers of these species during the day but that nectar secretion was nocturnal. The Blakea species involved are hemiepiphytic, and their flowers are positioned close to the stem where the rodents can reach them conveniently. The nectar of Blakea chlorantha contains ca. 1195 sucrose (Lumer, 1982, and pers. comm.); that of Huilea macrocarpa has 12-16% with a mean of 13.495 (Snow & Snow, 1980); that of Chalybea corymbifera 16.5%; and that of Brachyotum ledifolium 20-22% (Tobe et al., in prep.). It would thus be classified as relatively rich in sucrose in the nectar class system of Baker & Baker (1983), who found that sucrose-rich or su- crose-dominated nectar prevails in hummingbird flowers. Thus, nectariferous melastomes offer a reward “intended” for pollinators other than bees. The evolutionary origin of pollination systems involving nectar in Melastomataceae is considered below ll, pers. comm.). N MEMECYLACEAE In their pollination mechanism, the neotropical Memecylaceae closely resemble the Melastoma- taceae, and the above description of bees’ methods of pollen collecting from melastome flowers also applies to them. In Mouriri, the anthers are stiff, with thickened endothecial walls, and are slightly prolonged just above the insertion of the filaments. The prolongations, termed "caudae" (Morley, 1953), are used as footholds by the bees exploiting Mouriri anthers. Pollination in four species of Mou- riri has been observed (Table 4); the main polli- nators seem to be euglossines, followed by Xyloco- pa and Melipona species. They are legitimate visitors, i.e., large enough to contact the stigma regularly while collecting the reward. Memecyla- ceae anthers differ from those of Melastomataceae in bearing dorsal concave glands, 0.3-0.8 mm long. (For illustrations of the permutations in size and position of these glands in Mouriri and Vo- tomita, see Morley, 1953, 1976, and 1985.) None of the legitimate pollinators show any interest in the staminal glands (Buchmann & Buchmann, 1981; Renner, 1984, and unpubl.). Earlier (1984), I reported that Melipona mar- ginata and M. fulva sometimes collected the se- cretion from the glands with the front legs, and that they mixed this substance with their pollen loads between pollen-collecting bouts on the wing. Further field observations, however, have con- vinced me that Melipona does not regularly touch the glandular surface when buzzing. The bees grip the stamens by the anther caudas just below the glands, and it is difficult to see what they do with their feet or their mouth parts when vibrating be- cause they curve tightly over the anthers to allow the pollen stream to settle on their bodies. Between buzzing bouts, Melipona bees (and the euglossines) rotate over the androecium so as to drum out the pollen from all ten anthers. Staining of their freshly collected corbicular loads with Fehling solution showed that the pollen had been wetted with sugar. With Sudan III (a lipid stain), Mouriri pollen grains stained red, but the secretion holding them together did not; this implies that the pollen contains lipids, whereas the secretion did not. Mouriri flowers are also visited by several species of Trigona. These small bees do not regularly con- tact the stigma but rob pollen from the anthers, which they are unable to buzz. Their role as pollen scavengers and robbers in Melastomataceae is well known (Renner, 1983). When cutting up anthers of Mouriri nervosa to reach pollen grains further down, Trigona williana very rarely touched the glands (Renner, 1984, and unpubl.). Most often, T. williana cut off the anthers above the glands, then stopped and started cutting and robbing the pollen of another anther. This shows that this pollen robber, like the legitimate pollinators, does not reg- ularly collect the glandular exudates. Buchmann & Buchmann (1981) have observed T. pallens manipulating the glands of M. myrtilloides with the front legs and mouth parts. The secretion of the staminal glands is yellow, viscous, stains red in Sudan III, and tests positive 512 Annals of the Missouri Botanical Garden for fatty substances. That of the relatively large (0.8 mm long) glands of M. lunatanthera forms myelin figures in water after a drop of sodium hydroxide is added (pers. obs.; method from Vogel, 1974). The secretion in M. myrtilloides has been reported to be a lipoidal mixture of many com- pounds (e.g., phenolic Rud. small amounts 3 fatty acids, and free fatty acids) and to be * een rich in non- (Buchmann & Buchmann, of glucose and saponin, at least lipid constituents" 1981) Since the secretions from the floral glands con- tain lipids, the relationship between Mouriri and oil-collecting bees is of particular interest. Floral oils are collected by bees belonging to relatively few genera of Anthophoridae (e.g., Centris, Epi- charis, Monoeca, Paratetrapedia, Tapinotaspis, Tetrapedia; cf. Vogel, 1974; Ne Simpson, 1981). Although many of these collect pollen from Melastomataceae (comp. Table 4), to date only a single anthophorid bee species, Paratetrapedia calcarata, has been observed on Mouriri (Buch- mann & Buchmann, 1981). This bee, due to its small size (7-8 mm long), rarely vibrated more than two or three of the ten anthers in each flower and only rarely touched the stigma (l.c.). Also, Buchmann € Buchmann (1981) reported that Paratetrapedia calcarata was an infrequent vis- itor of M. myrtilloides (16 times during 50 hours) and not a legitimate pollinator. The secretion of the staminal glands forms a shiny film on the gland cuticle and in this respect differs greatly from the lipid-filled blisters of other epithelial elaiophores (Vogel, 1974). Paratetra- pedia has scrapers on the fore-basitarsi (Neff & Simpson, 1981) and ruptures the cuticle of the elaiophores from which it collects oils. While scru- tinizing hundreds of stamens from Mouriri nervosa and M. guianensis under the stereoscope in order to collect their glandular secretions, I never found signs of the glands having been scraped. This was perhaps to be expected, since the secretion forms a film on the outside of the cuticle. A further problem in understanding the role of the staminal glands is that they are so small and positioned in such a way that the collection of any exudate either with the fore-basitarsi or the mouth parts by the medium-sized bees that pollinate Mou- riri is difficult to envisage. Visitors small enough to be attracted by the minute quantities of secretion offered (such as the Paratetrapedia species ob- served by Buchmann & Buchmann, 1981) are not large enough to touch the stigmatic surface when manipulating the glands, especially since the styles in Mouriri are always longer than the stamens and the stigmas are held well away from the anthers. A possible role of the staminal glands suggested by Morley (1976) is odor production. Mouriri species often have a strong perfume scent (Buch- mann & Buchmann, 1981; Renner, 1984). Per- haps a volatile oil would persist longer when mixed with the fatty oils and other compounds. Buchmann & Buchmann (l.c.) suggested that the glands, which absorb ultraviolet light, might visually guide the bees to the pollen. Extending this idea, one might ascribe a pseudonectary role to the staminal glands. It is interesting that in the Bonnetiaceae, at least 23 species of Caraipa and Mahurea have very similar minute urceolate glands positioned subapi- cally on the connective (Kubitzki, 1978). The role of these glands, as of those of Mouriri, is obscure. SEED DisPERSAL IN MELASTOMATACEAE Of the neotropical Melastomataceae, 40% have capsular fruits and wind-dispersed seeds (Renner, 1986). The remaining 60% have soft, juicy berries and endozoochorous seeds. Animal-dispersed Me- lastomataceae are most diverse in lowlands and montane forests, whereas the capsular-fruited tribes are richest in species in various types of savannas. Melastome capsules are often sturdy and persist on the plants for many months, during which the seeds are gradually shaken out. There are no data on dispersal distances in the wind-dispersed species; however, the many striking disjunctions observed 1987b, press) probably attest to their good dispersability. in savanna melastomes (Renner, and in Small herbaceous understory species with broadly conical capsules ee O Bertolo- nia) may also have thei by raindrops. Melastome berries range in size from five to ca. d ballistically 35 mm in diameter. The smaller ones are of out- standing importance for small frugivorous birds throughout the Neotropics (Huber, 1910; Snow, 1965, 1971, 1981; Ricklefs, 1977; Skutch, 1980; Lumer, 1982; Wheelwright et al., 1984; R. Bier- regård, pers. comm., and many additional refer- ences). Epiphytic Melastomataceae are mostly bird- dispersed (Renner, 1986), as are many of the most successful pioneer species, for example, Clidemia hirta, which has become a noxious weed in Africa, Asia, and Hawaii. Fruit attributes, such as position, size, aroma, and color, indicate that different animal classes act as the principal dispersers in different species groups. For example, black spider monkeys are the pre- dominant consumers and likely dispersers of the green, slightly astringent and relatively large ber- ries of the tree Bellucia grossularioides in Suri- nam (Roosmalen, pers. comm. ). In French Guiana, Volume 76, Number 2 1989 Renner 513 Reproductive Biology in Melastomataceae & Memecylaceae this species is a favorite with the PAilander opos- sum (Atramentowicz, 1982), which also eats Hen- riettea and Loreya fruits. However, a search of recent literature on feeding records (Renner, 19872) showed that Melastomataceae are not among the preferred foods of either monkeys or bats (for bats, Fleming, 1986; but compare Foresta et al., 1984, and Fleming, 1988). Perhaps because the majority of Melastomataceae are shrubs or understory trees with terminally positioned infructescences, they are unsuited for foraging monkeys and bats. Also, the taste of the mostly sweet, watery melastome berries may not be to the liking of monkeys, which ap- parently prefer slightly acidic fruits (Sourd & Gau- tier-Hion, 1 ). Fruits that have fallen to the ground are often eaten by turtles (Moskowitz, pers. comm.; Roos- malen, pers. comm.), lizards (W. Magnusson, pers. comm.), rodents (Magnusson & Sanaiotti, 1987), tapirs (Huber, 1910), and ants (pers. obs.). SEED DISPERSAL IN MEMECYLACEAE All Memecylaceae have berries, ranging in size from 0.5 to 10 cm long; color at maturity is most commonly yellow to red, less often it is purple- black to black (Morley, 1976). The smaller-fruited species are surely bird dispersed; some larger-fruit- ed ones are monkey-dispersed (Roosmalen, 1985). Fish eat the fruits of at least one riverine Mouriri species (Goulding, 1980), which is curious, since Morley (1976) reported that two other species are used for poisoning fish. REPRODUCTIVE BIOLOGY AND THE EVOLUTION OF MELASTOMATACEAE AND MEMECYLACEAE Floral morphology in Melastomataceae and Me- mecylaceae can only be understood as the result of coevolution between the earliest ancestors of these groups and pollen-collecting bees. Flowers of the Old World members of both families have the same basic construction as those of their New World relatives and, although little information is available on their floral biology, van der Pijl's (1939) detailed description of the pollination mechanism in some species of Osbeckia, Medinilla, and Melastoma makes it likely that they are pollinated in the same manner as the New World ones. The pollen offered in the poricidal stamens of both families is acces- sible exclusively to bees, but not to many of the most common ones, such as the numerous species of Trigona and the paleotropical Apis, which ap- parently do not vibrate stamens. Most Melasto- mataceae and Memecylaceae have “modern” pol- len flowers in the sense of Vogel (1978), in which the visitor is forced into a fixed position while harvesting the reward and in which the position of the stigma is of relatively little consequence be- cause of the deposition of pollen on a large part of the visitor's surface There appears to be little opportunity for par- titioning the bee body. Sharing of pollinators, noted rather frequently among sympatric buzz flowers (Linsley € Cazier, 1963; Macior, 1970, 1971; Thorp & Estes, 1975; Lumer, 1982; Renner, 1984), results in hybridization in the absence of genetic barriers. This is consistent with the fact that systematists working with Melastomataceae and Memecylaceae often notice hybrids (Kral & Bostick, 1969; Whiffin, 1973; Morley, 1976; Al- meda, 1978; Solt & Wurdack, 1980; Renner, in press). The data on Melastomataceae breeding sys- tems corroborate the suggestion that apomixis may be more widespread in the tropics than formerly thought (Kaur et al., 1978; Ashton, pers. comm., 1987). Apomictic seed production would make such species independent of pollinators, while retaining the advantages of producing seeds, i.e., the poten- tial for dispersal and dormancy. Most notably, it would give them the capacity to build up a new population from a single propagule. Statements that “details of the structure of the anthers doubtless relate to mechanisms of polli- nation" (Cronquist, 1981) or “in a family, such as the Melastomataceae, where floral evolution has been extensive, one may logically conclude that the diverse floral types represent adaptations to different pollination systems” (Almeda, 1977) are not corroborated by field data. Rather, Melasto- mataceae seem to confirm Macior's (1971) sug- gestion that buzz pollination is so successful a sys- tem that, once it is established, hardly any other pollination mechanism evolves, even in species-rich groups. Compared with other families, such as Lecythidaceae, Gesneriaceae, and Bignoniaceae, for which the overall pollination spectrum is fairly well known, Melastomataceae and Memecylaceae show little diversification in floral morphology and pollination strategies. In this they resemble Mal- pighiaceae (Anderson, 1979) and Solanaceae (Sy- mon, 1979), which also have relatively specialized pollination systems and faithful bee pollinators. Such ack of diversification could be interpreted as the result of being stuck on an adaptive peak. Melastomataceae that offer nectar are pollinated by a broader range of pollinator classes, namely by hummingbirds, bats, rodents, and bees; this statement applies to the individual species as well, several of which have more than one important pollinator type, for instance birds and bats in Tibouchina grossa and bees and rodents in Blakea chlorantha. Cruden (1972) suggested, as a possible 514 Annals of the Missouri Botanical Garden ecological significance for nectar production at higher altitudes, that under adverse climatic con- ditions the homoiothermic birds and mammals may be more reliable pollinators than bees. If valid, this explanation would apply to all now known nectar- producing Melastomataceae, except the species of Miconia. Whether the thousands of pollen-only Melas- tomataceae derived from ancestors with nectar flowers or whether the proto-Melastomataceae nev- er possessed nectaries (as suggested by Vogel, 1978 is a difficult question. Phylogenetically, the extant nectariferous species belong to groups not closely related: Meriania and Centronia are in the cap- sular-fruited Merianieae (as is Axinaea, which probably also has some nectariferous species, see above) Brachyotum and Tibouchina are in the likewise capsular-fruited Tibouchineae; Chalybea, Huilea, and Miconia are in the berry-fruited Mi- conieae; and Blakea is in the also berry-fruited Blakeeae. Thus nectar production occurs in at least five evolutionary lines: the first leading to Meriania and Centronia (which are not closely related to each other) the second to Brachyotum and Tibouchina (the first genus is a segregate of the second; Wurdack, 1954), the third to Chalybea and Huilea (two intimately related genera), the fourth to Miconia (with 1,000 D only two of which to date are securely known to produc nectar), and the fifth to Blakea. dila could have n ida in all these lineages. oblem is confounded by the slits observed — in the hea of some non-nectariferous Mela- stomataceae exactly in the same position as in some of the nectariferous species, where nectar is se- creted through them. They occur in species of Heterocentron (Tibouchineae), Bertolonia (Ber- tolonieae), and Centradenia (Microlicieae) and in the paleotropical genera Medinilla and Dissotis (compare above under nectariferous melastomes) and may be rudimentary, nonfunctional nectaries. Thus, to date, only in two of the neotropical tribes— the small Rhexieae with 64 species and the Cy- phostyleae with nine species—are nectar produc- tion or presumed rudimentary nectaries absent. In view of the presence of nectaries in at least five neotropical lineages and the indications of their former presence in two further ones, their parallel independent origin becomes hard to accept. In- stead, I suggest that the capacity for developing nectaries is basic in the Melastomataceae but sup- pressed in most modern members. To understand the origin of the memecyloid connective gland, whatever the chemical compo- sition of its secretion, the following observations seem relevant. Functioning nectaries have been observed on the hypanthia of Memecylon edule Roxb. (= M. ramiflorum Desr.; Burck, 1 )an M. floribundum Blume (Zimmermann, 1932). Also, I have frequently seen ants on the hypanthia of Mouriri nervosa, which may be an indication that this neotropical Memecylaceae also secretes e albeit in minute quantities. Evolutionarily, the c pacity to secrete minute quantities of dece directly through the hypanthium epidermis, with- out conspicuous morphological structures, may be correlated with the development of the staminal glands. However, data on the pollinators and the chemical composition of the exudates of paleo- tropical Memecylaceae are needed before the sig- nificance of the staminal glands in the family as a whole can be assessed. The Memecylaceae have a. 340 Old World and 89 New World species, and it should be noted that, in the opinion of Morley (1953), the New World Memecylaceae are more basal than the Old World ones. There is a great amount of parallelism between the Old World and the New World tribes in the Melastomataceae: the Oxysporeae, Sonerileae, Dis- sochaeteae, and Osbeckieae resemble more or less closely the Merianieae, Bertolonieae, Miconieae, and Tibouchineae, respectively, of the New World (Gleason, 1932). Based on wood anatomy, the dif- ferentiation into at least some of these tribes and into Melastomataceae and Memecylaceae occurred before the breakup of Pangaea (Vliet et al., 1981). However, the coevolutionary relationships between bees and proto-Melastomataceae, which are a con- O ditio sine qua non for the evolution of the mela- stome androecium, can only have begun during the mid-Cretaceous when bees arose (Michener, 1979). The mid-Cretaceous may thus have been the time when the ancestors of these families switched from nectar-reward flowers to pollen-re- ward flowers (with the pollen presented in poricidal anthers and available only to bees). Likely, the Melastomataceae and Memecylaceae originated during Aptian times (lower mid-Cretaceous, 11 million years before present), when the gap between Brazil and Ghana was still very narrow; their east and west Gondwanian lineages, probably coevolved in parallel with the earliest bees. The oldest fossil melastome leaves are known from the early Eocene (Hickey, 1977), about 53 million years before pres- ent, and Eocene and Miocene leaves occur widely scattered throughout the Northern Hemisphere (Wurdack & Kral, 1982). Therefore, members of the family (and some of their pollinators?) at one time may have dispersed via Europe between North America and Africa. The Melastomataceae, with two-thirds of their species in the Neotropics, have much of their di- Volume 76, Number 2 1989 Renner 515 Reproductive Biology in Melastomataceae & Memecylaceae versity centered in areas of varied topography — the Andes, Guayana, and south-central Brazil. The neotropical Memecylaceae, on the other hand, are centered in the Amazonian lowlands, where they appear adapted to different soil types (pers. obs.). The very early shift from anemochory to zoochory in the Melastomataceae was probably one of the reasons for their success in the understory of closed forests, where animal dispersal is more advanta- geous than wind dispersal. (The capsular-fruited tribes are much more diverse in open habitats and have relatively few species in forests.) The crucial points in the radiation of large groups within the Melastomataceae, besides their different seed-dis- persal strategies, have been the acquisition of par- ticular plant architectural, indument, and leaf ve- nation characters. Because adaptations to different pollinator types played such a limited role in the radiation within the two families, the floral biolog- ical data cannot be used to support either of the two suggested phylogenies for the Melastomataceae (Wurdack in Welle & Koek-Noorman, 1981; Vliet et al., 1981).

Bruce A.

Within the order Myrtales, this type of nonstructural androecial nectary is limited to Melastomataceae and is apparently very rare among angiosperms as a whole. Two additional methods eve explanation for the diversity of nectary types within the family and for the scattered phylogenetic positions of nectar producing taxa The family Melastomataceae, with ca. 200 gen- era and 4,500-5,000 species, is the largest in the order Myrtales. This primarily tropical family is distributed worldwide but particularly well repre- sented in tropical and subtropical areas of the New World. Most members of the family produce no floral nectar, relying instead on pollen as the prin- cipal pollinator reward (for review see Renner, this volume). Species in at least two genera, Tibouchina (= Purpurella) (Ule, 1896) and Brachyotum (Lagerheim, 1899), however, have long been known to produce nectar. Additional observations of nec- tar production, or presumed production, have been made more recently on these and several other melastome genera, including Blakea (Lumer, 1980; Lumer & Schoer, 1986), Huilaea (Snow & Snow, 1980), and Miconia (Mori & Pipoly, 1984). Most reports that note the location of nectar secretion within the flower generally found the nectar to emanate from the stamens. This strongly contrasts with the situation in most myrtalean families in which floral nectaries are located either on the floral tube, the gynoecium, or at the floral tube-gynoe- cium junction. oral nectaries of Melastomataceae have been little studied, and nothing has been reported pre- ' Our special thanks to Peter H.

The pri- mary purpose of this study is to elucidate the struc- ture of Melastomataceae nectaries through anatomical examination and to confirm the unusual location of nectar secretion through field obser- vations. Our investigation of floral nectary struc- ture extends to representative genera of Me- a family traditionally included in Melastomataceae as a tribe or subfamily. The an- mec ylaceae, ther connective of Memecylaceae contains a dis- tinctive depressed gland structure that had previ- ously been described as a nectary (Burck, 1891; Subramanyam, 1949). In Mouriri, however, these glands have recently been found to secrete a lipid- rich substance, suggesting that they are elaiophores (Buchmann & Buchmann, 1981 MATERIALS AND METHODS We examined anatomically flowers of 40 species in 17 genera of Melastomataceae, representing known nectar producers and genera and species not reported to secrete nectar. In addition, six species of Memecylaceae in three investigated. FAA-fixed collections were made by the authors and by numerous collaborators world- wide (Table After dehruration through a t-butyl alcohol se- ries and embedding in Paraplast with MP 57- 58 C?, flowers (and sometimes stamens alone) were enera were sectioned transversely and longitudinally at 8-10 um thickness; the sections were stained with he- matoxylin, safranin, and fastgreen FCF and were mounted with Entellan. Dark staining by hema- toxylin represents a concentration of cytoplasm in cells, indicating high metabolic activity such as seen in active nectaries. In other families of the Myr- tales, this staining method has fully demonstrated the location and size of nectariferous tissue (Tobe, pers. obs.); if present, nectaries are thus easily distinguished from other tissue by their dense stain- ing. We noticed that certain species, particularly those known to secrete nectar, have a conspicu- ously thickened staminal vascular bundle. Thus, for comparative purposes, the thickness of the staminal vascular bundle is presented as a relative value (Table 1). The “relative thickness" of stamen vascular bundles is calculated as: radial thickness of the vascular bundle (t)/radial thickness of the filament (T). Calculations were made on the basis of two or three stamens. Relative thickness values are presented as a range, since the thickness of the filament and the vascular bundle can differ at varying points along the same filament. Field observations of nectar secretion in Brachyotum, Chalybea, and Tibouchina were conducted while field collecting floral material for this study. Fresh flowers were examined for evi- dence of nectar, and the location of nectar secretion within the flower was noted. Nectar quantity and sugar concentration were measured using micro- capillary tubes and a Reichert temperature-com- pensated hand refractometer (model 10431). Nec- tar sugar concentration measurements (% brix) were subsequently converted to sucrose-equiva- lents (weight by total weight). RESULTS We did not detect densely staining structural nectaries in the flowers of any of the species ex- amined of Melastomataceae and Memecylaceae. Three significant features were noted, however. First, stamens of some melastomes, particularly those known to secrete nectar, have a markedly thickened vascular bundle in relation to the fila- ment or anther connective. Relative thickness of staminal vascular bundles of nectar-producing and non-nectar-producing species are presented in Ta- ble 1. The relative thickness values of staminal vascular bundles in nectar-producers normally ex- ceed 0.3 (mean 0.34), whereas stomes examined range between 0.1 and 0.3 (mean 0.23), a statistically significant difference (P < 0.001). Second, although no densely staining struc- most other mela- — tural nectaries were found, many of these thickened vascular bundles showed relatively dark-staining phloem cells, indicating that they are cytoplasm rich and may be fulfilling a nectary function. Third, many of the nectar-secreting species have external slits that develop on or near the geniculum of the filament and that may represent a nectar emission pathway. Information on the site of nectar secretion and on known or putative pollination vectors for nectar- producing Melastomataceae is summarized in Table 2. Examined genera that are known or strongly suspected to produce nectar are discussed individ- ually below. Members of several other genera may also secrete nectar but were not examined. These include two additional Andean genera that hum- mingbirds have recently been observed visiting, Centronia excelsa (Bonpl.) DC. (Neill, pers. comm., 1987) and Meriania tomentosa (Cogn.)

Two additional nectar-producing species have recently been reported, B. austin- smithii Standl. and B. penduliflora Almeda (Lu- mer & Schoer, 1986). There is some disagreement concerning the site from which nectar is secreted in this genus. Lumer (1980, and pers. comm., 1985) stated that in B. chlorantha nectar appears to be secreted in the area at the base of the stamens, either at the junction of the filament and floral tube or at the base of the filaments. According to Haber (pers. comm., 1985), however, nectar is secreted on the abaxial surface of the filaments (the side facing the corolla wall), with the nectar forming thick droplets between the filament and the corolla. Anatomical sections of Blakea chlorantha flow- ers do not show a densely staining nectary any- where on the floral tube wall (Fig. 1), nor do sta- mens have an externally or internally differentiated nectariferous structure (Figs. 2, 3). Stamens are folded inward in bud, with a geniculum present just above the midpoint. Slitlike structures are present on the adaxial surface of the geniculum (arrows in Figs. 1-3). The relative thickness value of the vascular bundles is fairly low (0.21-0.27) com- pared with other nectar producers (Fig. 5). These vascular bundles, however, are relatively densely staining, particularly in the upper part of the fil- ament and at the connective (Figs. 3-5). A major part of the staminal vascular bundle appears to consist of small, cular bundle are not specialized (Figs. 4, 5), sug- gesting that they are not nectariferous. Stamens of Blakea sp. nov. (fide F. Almeda) and B. foliacea are folded inward in bud at the anther—filament junction, and filament slits are not present. Although, like B/akea chlorantha, they have a thin more or less densely staining vascular bundle, they differ in that the staminal vascular bundle is surrounded by a thick-walled tanniferous epidermis and by some underlying tanniferous cell layers. Blakea sp. nov. and B. foliacea stamens are unlikely to secrete nectar through such tan- niferous tissue, and nectar production has never been reported in either of these two species. Brachyotum.

From field observations, the nectar appears to be secreted by the filament at the slitlike structure located on or just below the geniculum on the adaxial filament face (Fig. 6) and forms large droplets suspended between adjacent pairs of filaments. Nectar con- centration ranged from a high of 20-22% sucrose- equivalents in B. ledifolium (Desr.) Triana to a low of 15-16.5% in B. campanulare (Bonpl.) Triana, values consistent with most hummingbird- pollinated flowers (Baker, 1975). natomical sections of stamens do not show any differentiated nectariferous structure in the fila- ments. Stamens of Brachyotum ledifolium have a thick vascular bundle running the length of the filament (Fig. 7) to the connective (Fig. 8). The staminal vascular bundle is densely staining and contrasts with the surrounding nonspecialized parenchyma cells. All other examined species of Brachyotum contain a similar thick, densely stain- ing staminal vascular bundle: B. campanulare (Fig. 10), B. lindenii Cogn., B. microdon (Naud.) Triana, and B. sanguinolentum (Naud.) Triana (Fig. 9). This similarity in staminal anatomy suggests that all these species exude nectar from the filament. Chalybea. | Chalybea is a monotypic genus of the Colombian Andes closely related to, if not con- generic with, the nectar-producing genus Huilaea. Poorly known and consisting only of C. corymbif- era Naud. (= Pachyanthus corymbiferus [ Naud. | Cogn.), Chalybea recently has been resurrected on the basis of material newly collected for this study (Wurdack, 1988). We have observed nectar secretion from C. corymbifera and measured the nectar sugar concentration at 16.5% sucrose- equivalents. Pinpointing the site of secretion is problematic. Nectar was collected from the summit of the inferior ovary; however, the nectar was observed and measured several hours after the normally pendulous flowers were collected and could have migrated to this location. Stamens are bent inward in bud and have neither a pronounced ge- niculum nor filament slits (Figs. 11, 12). Anatom- ical sections do not show a differentiated nectarifer- ous structure at the ovary summit (Fig. 11). While stamens do not have either externally differentiated structures or densely staining nectariferous tissue (Figs. 11, 12), they do contain a thick vascular bundle running through the filament (Fig. 14) to the connective (Fig. 13), suggesting staminal se- cretion. Tanniferous parenchyma cells surrounding the staminal vascular bundle appear unfavorable 524 Annals of the Missouri Botanical Garden FIGURES 1-5.

These tanniferous cells, however, are much less conspicuous in the lower part of the filament, and nectar thus may exude from the filament in this location, perhaps ac- counting for its observed presence on the ovary summit. Huilaea. Snow & Snow (1980) reported nectar production by Huilaea macrocarpa Uribe and measured the nectar sugar concentration to range from 12 to 16% with a mean of 13.4%. No in- formation was provided as to the precise location of nectar secretion in these pendulous flowers. Tibouchina. examined, including the Andean T. grossa, which is known to produce nectar.

(Ule, 1896). Our observa- tions of nectar secretion in T. grossa differ somewhat from those of Vogel (1957), who considered the nectar to exude from the inner wall of the floral tube below the insertion of the stamens. 7ibouchina grossa flowers are open-campanulate and oriented horizontally with all stamens arranged in a half- circle in the lower side of the corolla. We observed nectar droplets forming on the adaxial surfaces of the filaments near the geniculum. The drops are at first suspended between adjacent filaments and occasionally between the filaments and style. The rather copious nectar then flows down the filaments to collect either in the floral tube or on the convex lower petals. We measured sugar concentration of T. grossa nectar at 14.5% sucrose-equivalents. No densely staining differentiated structure was found in the filaments of Tibouchina grossa (Fig. Volume 76, Number 2 Stein & Tobe 525 1989 Floral Nectaries in Melastomataceae FIGURES 6-10.

Medinilla. The Old World genus Medinilla in- cludes certain species that morphologically appear to be good candidates for bird pollination.

Anatomical in- vestigations of this very unique nectar secretion method are currently under way (Tobe et al., in prep). Miconia. |n discussing a mass flowering episode of Miconia minutiflora (Bonpl.) DC, Mori & Pipoly (1984) reported the presence of nectar as a pol- linator reward in this species. In other localities, however, this lowland species has not been found to secrete nectar (Renner, 1983). Only young buds of Miconia minutiflora were Volume 76, Number 2 1989 Stein & Tobe 527 Floral Nectaries in Melastomataceae available for the present study. Anatomical sections of this material indicate no structure likely to pro- duce nectar in either the stamens or around the floral tube-gynoecium junction (Fig. 18). Flowers are very small, with the filaments supplied by a relatively thin vascular bundle (Fig. 19). Anatom- ical sections show, however, that M. minutiflora has a remarkably conspicuous stigma supplied by ample, densely staining vascular tissue (Fig. 18). Hummingbirds have been observed visiting Mi- conia melanotricha (Triana) Gleason (Almeda, pers. comm., 1986), and this species may produce nec- tar. The flowers appear morphologically well suited for hummingbird pollination, given their large size (10-15 mm in diameter an -25 mm long) and red petals. This species also has longitudinally de- hiscent anthers rather than the apically poricidal anthers typical of bee-pollinated melastomes. An- atomical sections do not show densely staining structures or tissue, and the stamens have a thin vascular bundle (Fig. 21). As in M. minutiflora, however, the stigma and supporting vascular tissue are unusually densely staining (Fig. iconia robinsoniana Cogn. was reported to produce nectar in a survey of the foraging ecology of the Galápagos Islands carpenter bee, Xylocopa darwinii (Linsley et al., 1966). Subsequent obser- vations of this species have not reconfirmed the presence of nectar (McMullen, pers. comm. in Ren- ner, this volume). During our own field investiga- tions of this species, no suitable material could located to resolve this question. An additional, as yet unidentified, Miconia species from lowland Amazonia has recently been reported to produce nectar (Roubik, pers. comm. in Renner, this vol- ume). MEMECYLACEAE Memecylon and Mouriri have a peculiar de- pressed gland on the backside of the anther con- nective (Figs. 22, ). This structure was early escribed as a nectary (Burck, 1891; Subraman- yam, 1949; Venkatesh, 1955) but recently has been hypothesized to be an elaiophore, or oil-pro- ducing gland (Buchmann & Buchmann, 1981). Anatomical sections reveal this gland to be com- posed of more or less radially enlarged epidermal cells, which are clearly distinguishable from other cells of the connective (Figs. 23, 25). Pternandra is variously included in or excluded from the Memecylaceae. Its uncertain status is based largely on the absence of the anther con- nective glands found in other members of Me- mecylaceae. The two species examined in this study, P. caerulescens Jack. and P. echinata Jack., lack these gland structures on the surface (Figs. 26, 2'7) and in section (Fig. 28) DISCUSSION POSITION AND STRUCTURE OF FLORAL NECTARIES IN MELASTOMATACEAE The present study shows that, in contrast to nearly all other myrtalean families, Melastomata- ceae lack histologically differentiated nectariferous tissue either on the inner surface of the floral tube, on the gynoecium, or at the floral tube-gynoecium junction. While nectar production in Melastoma- taceae is rare, a diversity of unusual nectary types are implicated, including secretion from the sta- mens, petals, and perhaps stigmas. Most docu- mented nectar-producing melastomes secrete nec- tar from the stamens, although we did not find any differentiated nectariferous structures or tissue in that organ. On the basis of observations and an- atomical structure, we thus conclude that in most nectariferous Melastomataceae nectar is produced by a nonstructural nectary consisting solely of the staminal vascular bundles. Compared with melastome species generally, stamens of nectar-producers have a much thicker vascular bundle containing many small, densely staining cytoplasm-rich phloem cells. An ultra- structural survey of these cells could offer addi- tional evidence of their nectar-secreting capability, since there is a clear connection between cytolog- ical constituents and processes of nectar secretion (for review of ultrastructural features see Fahn, 1979). The nonlocalized nature of these androecial nec- taries may help resolve the g reports about the specific sites of nectar secretion (Table 2). If nectar is produced by the staminal vascular bundle, it could emanate from almost anywhere along the stamen. Additionally, if the direction of the nectar stream within a stamen is affected by gravity, the d secretion site could differ between stamens an among individual flowers. Several observers, including one of us (B.A.S.), have noticed that in certain genera (e.g., Brachy- otum and Tibouchina) the location of nectar se- cretion appears to be closely associated with a small slit in the adaxial surface of the filament (see arrows in Figs. 1-3, 6). The development and significance of these slits is somewhat controversial. We found no anatomical differentiation of this structure. Since stamens in Melastomataceae are folded or bent inward in bud, becoming more or less straight at anthesis, the observed slitlike structures may form spontaneously and be unrelated to nectar secretion. 528 Annals of the Missouri Botanical Garden IGURES 22-28.

However, an apparent association of these slits with nectar-producing species, their absence in related non-nectariferous species (e.g., Blakea chlorantha vs. B. sp. nov. and B. foliacea), and field obser- vations of nectar droplets formed precisely at these indentations strongly argue for a role in nectar secretion ese structures may form through a deterlonition of a small amount of tissue on the inner side of the geniculum, providing an exit path- way for nectar produced by the staminal vascular bundle. Clearly, a systematic survey of the occur- rence of these slits throughout the Melastomata- ceae would be useful in clarifying their role.

From our anatomical examination, creting nectar from the stamens in the manner of the other confirmed nectar-producers we investi- gated. If nectar production in this species is re- confirmed, the conspicuous stigma, which is sub- tended by cytoplasm-rich vascular tissue, should be closely examined for a possible secretory role. Stigmatic nectar secretion is rare within the an- giosperms but occurs in Asclepiadaceae and Ara- ceae (Fahn, 1979). EVOLUTION OF FLORAL MELASTOMATACEAE NECTARIES IN Nectaries generally consist of an epidermis sub- tended by specialized parenchyma cells (Esau, 1977; Volume 76, Number 2 1989 Stein & Tobe Floral Nectaries in Melastomataceae 529 Fahn, 1979). The phloem-based nectaries we have found in Melastomataceae, which have no struc- turally differentiated parenchyma, are a rather ex- treme deviation from this typical structure. The nonstructural androecial nectaries found in Melas- tomataceae are particularly anomalous in Myrtales, where, of the 14 families currently included in the order (Dahlgren & Thorne, 1984), only Melasto- mataceae, Memecylaceae, and Rhynchocalyca- ceae lack densely staining structural nectaries. Eyde (1981) has discussed evolutionary shifts in the lo- cation of floral nectaries in flowers of various myr- talean families and concluded that the ancestral site of nectar secretion for Myrtales, as for many other dicots, is the junction between the gynoecium and the floral tube or, in tubeless flowers, the junc- tion with the androecium. From this ancestral po- sition, nectaries evolutionarily have migrated onto the floral tube, or even onto the androecium in some tubeless species of Lopezia and Epilobium of the Onagraceae (Eyde & Morgan, 1973; Eyde, 1981). Androecial nectaries are also found in other groups, including virtually all members of the Cary- ophyllales (Zandonella, 1977 droecial nectaries in these other families are more typical differentiated structures and thus not com- parable to the nonstructural androecial nectaries of Melastomataceae, which are certainly unique within the Myrtales and perhaps among angio- sperms as a whole. Given the ancestral myrtalean nectary type and position proposed by Eyde (1981), it seems clear that structural nectaries were lost in the evolu- . However, the an- tionary lineage ancestral to Melastomataceae and Memecylaceae. Such nectaries appear to have been lost independently in the lineage leading to Rhyn- chocalycaceae (a monotypic family consisting only of the South African Rhynchocalyx lawsonioides Oliver), since on many other grounds this family is more closely related to other members of the Myrtales than to Melastomataceae (Tobe & Raven, 1984). Pollinator interactions appear to have played a key role in both the ancestral loss and subsequent re-evolution of nectaries within the Melastomata- ceae. Melastomataceae are, on the whole, a famil uniquely suited for bee pollination. The distinctive poricidally dehiscent anthers are directly related to vibratile extraction of pollen by bees, a phe- nomenon known as buzz pollination. Bees foraging for pollen in this manner rarely forage simulta- neously for nectar, and then only to mix it with the pollen to improve the pollen's handling prop- erties (Buchmann, 1983). Although poricidal an- thers are found in numerous angiosperms (for re- view see Buchmann, 1983), few plant families are so completely characterized by this feature as Me- lastomataceae. Given the widespread distribution of poricidal anthers within all lineages of Melas- tomataceae, this feature appears to be the ancestral condition for the family. Thus, if buzz pollination became established in the lineage ancestral to Me- lastomataceae, there would be little or no selective advantage in maintaining energy-expensive nec- taries. By attracting undesirable and potentially destructive floral visitors, nectaries may even have been selected against in protomelastomes. Nectaries appear to have re-evolved indepen- dently in several distinct lineages within the family, most of which share certain ecological and repro- ductive traits. Cruden (1972) has pointed out the potential reproductive advantage ensuing from a shift from bee to bird pollination in wet-tropical montane ecosystems. Similarly, Heinrich & Raven 1972) have noted the increased energy reward necessary to attract pollinators operating at higher elevations and to support vertebrate rather than invertebrate pollinators. Nectar, composed prin- cipally of carbohydrates, is a much richer energy source than pollen and is almost invariably the floral reward used to attract vertebrate pollinators. Not surprisingly, most confirmed nectar-producing Melastomataceae (species of Blakea, Brachy- otum, Chalybea, Huilaea, and Tibouchina) occur at high or relatively high elevations, and are known or presumed to be pollinated by vertebrates (Table — According to traditional and recent classification systems for the family (Cogniaux, 1891; van Vliet et al., 1981; Wurdack, 1980), confirmed nectar- producing Melastomataceae are found in at least four different tribes: Blakeae, Dissochaeteae, Mi- conieae, and Tibouchineae (see Table 1). The phy- monophyletic lineage within the family. In addition, the majority of genera in these four tribes are not known to produce nectar. Except for the lowland species of Miconia discussed above, most of the nectar-producing taxa can be viewed as —— derived within their respective tribes in s of pollination systems and ecological/ aia! pubs erences. With regard to the latter, the Central and northwestern South American montane terrains that are inhabited by many of these species (and, if the above interpretation is correct, may have provided the ecological impetus for the development of nec- tar rewards) are generally more recent (Zeil, 1979) 530 Annals of the Missouri Botanical Garden than the origin of the Melastomataceae, fossils of which are known from as early as Eocene times (Hickey, 1977). wo hypotheses can be advanced to account for the unusual systematic distribution of nectaries within the family. The first is that such nectaries are the basal condition in Melastomataceae and have been lost in the vast majority of species. Civen the structural nectaries present in other families of Myrtales and the rather specialized morpholog- ical state of most of the nectariferous species, how- ever, such an interpretation is untenable. Renner (this volume) advocates a modified version of this hypothesis, suggesting that “the capacity for de- veloping nectaries is basic in the Melastomataceae but suppressed in most modern members.” This supposition seems equally difficult to accept. Rath- er, we propose a second hypothesis, which is that nectaries have evolved independently a number of times within the family and developmentally have followed the easiest course available. T evidence point to this. First, three different nectary types have developed within the family, each in- e. Two lines of volving different floral organs (stamens, pistil, pet- als). Although rare within angiosperms, the most common melastome nectaries, nonstructural an- droecial nectaries, involve very little modification of existing structures and thus appear to be an ipd developed solution to producing nectar. It is cult, however, to reconcile this view of the ease of developing such nectaries with the relative rarity of nonstructural androecial nectaries in the angio- sperms as a whole SYSTEMATIC IMPLICATIONS OF NECTARY ANATOMY FOR MEMECYLACEAE Memecylaceae traditionally have been included in Melastomataceae as a tribe or subfamily (e.g., Cogniaux, 1891; Morley, 1976). Based on floral nectary characters, Memecylaceae agree with Me- lastomataceae in completely lacking densely stain- ing structural nectaries. The term “disc” has some- times been used to describe certain structures within the flowers of Memecylon (see Bremer, 1983). Given the complete lack of nectariferous tissue, this term should, however, be avoided. As previ- ously discussed, loss of structural nectaries seems to be a feature ancestral for Melastomataceae, and this is probably also the case for Memecylaceae. We regard loss of structural nectaries as a syn- apomorphy uniting these two families. Memecylaceae have generally been circum- scribed to include the Old World Memecylon and the New World Mouriri and Votomita, all con- taining anther connective glands. Based on obser- vations of Mouriri myrtilloides (Sw.) Poir, Buch- mann & Buchmann (1981) suggested that the connective glands of Memecylaceae are elaio- phores that secrete lipids for nutritional use b pollinating bees, primarily in larval o Although the secretion is lipid rich, its chemic complexity and the presence of components seem- ingly toxic to insects have led others to be cautious about this interpretation (Renner, this volume; Simpson & l Morley (1976) considered these distinctive but little-understood connective glands to be one of the most characteristic features of the "Memecyleae' (7 Memecylaceae), even though they are occa- sionally lost, as in Mouriri exadenia Morley. Whatever its taxonomic rank, the group is now generally considered to include additional genera, among them Pternandra, which lacks connective glands (Dahlgren & Thorne, 1984). The present study reconfirms this observation: all examined species of Memecylon and Mouriri have anther glands on the backside of the connective, whereas all examined species of Pternandra lack them. Therefore, even if Pternandra is aligned with Me- mecylon, Mouriri, and Votomita at the familial level, evolution of the anther glands appears re- stricted to the lineage including the three last- mentioned genera. Available evidence from stam- inal anatomy does not resolve the correct familial placement of Pternandra but does suggest that if included in Memecylaceae, it should be regarded as the sister group to the rest of the family. This is generally the approach taken by van Vliet et al. (1981) in placing Pternandra in its own tribe Pter- nandreae of their “Memecyloideae” (= Memecy- laceae). LITERATURE CITED Baker, H. G. 1975.

Unique characters of the section include the nina violet, convolut Southern Hemisphere. With the Old World sect. Skinnera as the sister group of all the American species of Fuchsia, sect. Quelusia represents an early offshoot of the ancestral South American fuchsias, distinct from the tropical Andean and Central American sections in its polyploidy and derived, 3-porate pollen. The nearest relative and sister species of sect. Quelusia i is i lycioides, a specialized xerophyte and the sole member of sect. Kierschlegeria, which occurs in central Chile just north of the range of F. magellanica. The Andean and Brazilian populations of sect.

The genus con- sists mostly of mesic shrubs confined to cool, moist habitats, with nearly 34 of the species concentrated in the tropical Andes. The remaining species occur in Mexico and Central America, Hispaniola, south- eastern Brazil, the southern Andes, New Zealand, and Tahiti. In recent years, Fuchsia has been the subject of a series of studies designed to refine the tax- onomy and to improve our understanding of the evolutionary relationships within the group.

Quelusia array of species have helped to define sectional limits by detecting consistent differences in viscin types, aperture number, and grain size (Skvarla et al., 1976, 1978; Nowicke et al., 1984; Praglowski et al., 1983). Systematic revisions for seven of the ten sections in the genus have been completed, based on broad cytological surveys, a thorough review of the major collections of her- barium specimens, and extensive field examination of natural populations (Breedlove, 1969; Berry, 1982, 1985; Breedlove et al., 1982; Berry et al., 1988). The present study uses the same method- ology to produce a revision of the species of sect. Quelusia, a group centered in southeastern Brazil and forming the largest section outside of the trop- ical Andes. A better understanding of the systematics of sect. Quelusia is particularly desirable, as the species form a closely related, yet unspecialized group that may have retained many of the primitive char- acters of the genus. Biogeographically, the section is confined to ancient forest areas in the southern Andes and in southeastern Brazil that show clear austral-Antarctic affinities. Ultimately, this may have been the source area from which other sec- tions differentiated and spread both to Australasia, when more or less direct overland connections were possible across Antarctica until the mid-Tertiary, and to Central America, where several small sec- thread tions presently occur orticulturally, most of the hundreds of hybrid Fuchsia cultivars have been derived primarily from members of sect. Quelusia (Reiter, 1944), yet there has been much confusion as to which taxa were involved in the early crosses. Accurate information on the different native species of sect. Quelusia can also be expected to stimulate interest in their preservation, cultivation, and use in hybridization for new ornamental cultivars. In the only recent monograph of Fuchsia, Munz (1943) recognized five species in sect. Quelusia, together with Fuchsia hybrida Hort. ex. Vilm., a name used to encompass most of the common garden hybrids. Fuchsia magellanica and F. regia included three and four varieties, respectively; these species have the broadest geographical distributions in the genus and also show complex patterns of morphological variation. In this study, Fuchsia magellanica is treated as a single, cytologically uniform, polymorphic species with no clear geo- graphical pattern of differentiation. Fuchsia regia, on the other hand, has tetraploid and octoploid populations, with geographically differentiated variants that are treated here as comprising three intergrading subspecies. Both F. alpestris and F. glazioviana are reinstated as distinct species, and two previously unrecognized species are described, F. brevilobis and F. hatschbachii. As herein de- limited, sect. Quelusia consists of 11 taxa, with nine different species. HABITAT AND DISTRIBUTION Fuchsia sect. Quelusia is an entirely Southern Hemisphere group of species, bs. a latitudinal range extending from 18*S to outh America in two large vi widely disjunct areas: the southern, temperate Andes of Chile and Argentina, and the coastal mountains and high plains of southeastern Brazil (Fig. 1). The only species occurring in the southern An- des is F. magellanica, which is characteristic of the wet, temperate, Valdivian forests that are cen- tered in the Región de Los Lagos of Chile. These forests are considered to be relicts of an ancient vegetation type that includes many taxa of Aus- tralasian affinity, such as Nothofagus, Drimys, Podocarpus, and Araucaria (Rambo, 1951; Hueck, 1972; Lötschert, 1981). Fuchsia magel- lanica also extends farther north into drier areas in Chile, where it occurs in moist microhabitats as . It occurs in far north as Santiago and Valparaiso, and then southward to the subantarctic scrub forests of Tier- ra del Fuego. Throughout its range, F. magellan- ica occurs as low as sea level, but only at its northernmost range does it reach its upper alti- tudinal limit of 1,750 m. Seasonality increases southwards, so that in Tierra del Fuego, flowering is restricted to the summer months of December to March, and plants are strongly deciduous in the freezing winter months. e other sie species of the section all occur in the highlands of southeastern Brazil. A single species, F. regia, is widespread and covers the entire range of the section in Brazil, from 18?20'S to 29930'S. The remaining species have much more restricted distributions, several occurring on a sin- gle mountain range. Fuchsia regia consists of three largely allopatric subspecies Subspe ec ies mainly in dense dawa forests at the crests and on the seaward- facing escarpments of the coastal mountains from Rio Grande do Sul to northern São Paulo state, at elevations of 500-1,450 m. In Santa Catarina, however, it is also found in enclaves of montane vegetation on the summits of the isolated *morros" that emerge just 100 to 300 m above the Atlantic lowland forest in the Itajai Valley (Klein, 1978). It has also been found at sea level in restinga forests near the Santa Catarina- Rio Grande do Sul border, 534 Annals of the Missouri Botanical Garden where Reitz (1961) found a number of other plants typical of the high inland serras. Fuchsia regia subsp. reitzii is restricted to thickets and low forest on the drier planalto, or southern highlands, that occupies much of the in- terior of Paraná, Santa Catarina, and Rio Grande do He It occurs at altitudes between 900 and m in areas subject to strong winter frosts ed 1984). The range of subsp. reitzii in this area coincides quite closely with Araucaria an- gustifolia, the dominant element of the planalto forests (Hueck, 1953). In Rio Grande do Sul and southern Santa Catarina, the joris ends abruptly to the east at the **Aparados” or ** ' sheer cliffs that drop down beh of meters to the Atlantic coastal plains. At these sites, subsp. reitzii reaches its eastern limit, growing sympatrically along a narrow band with the westernmost popu- aimbes,' lations of subsp. serrae. Fuchsia regia subsp. regia occurs further north in a series of separate mountain systems, from northern Sào Paulo to Rio de Janeiro, Minas Gerais, and Espirito Santo. It grows in cloud forests be- ginning at 1,000 m and reaches open campos above treeline as high as 2,400 m on Mt. Itatiaia. Several species are restricted to high altitudes and are known from just one area. Fuchsia bra- celinae grows only between 2,300 and 2,850 m, above treeline in the “campos de altitude" of a few peaks of the Serra do Caparaó. This is the highest mountain range of southern Brazil, situated along the Minas Gerais- Espirito Santo border. Sim- ilarly, F. campos-portoi occurs only in campos around Mt. Itatiaia, in the Serra da Mantiqueira, between 2,100 and 2,550 m. Fuchsia coccinea occurs naturally only at the summit of four of the highest mountains in Minas Gerais, between 1,400 and 2,000 m Two species are endemic to several of the high, granitic *morros" characteristic of the Serra do Mar in Rio de Janeiro state. Fuchsia alpestris grows among bushes at the base of granitic outcrops in the Serra dos Órgãos and around Santa Maria Madalena. Fuchsia glazioviana is found as high as 2,100 m in open campo vegetation on morros around Nova Friburgo and Santa Maria Madalena. It also descends into e forest as low as 1,500 m on the same mountai Two newly described pcm from Paraná and southern Sáo Paulo states have broader ranges. Fuchsia brevilobis occurs in forests of low, inland mountain ranges at 600—900 m, but on the eastern slopes of the Serra do Mar in Paraná, it is found from 400 m to sea level. Fuchsia hatschbachii occurs further inland in Paraná, in drier forests than the coastal mountains, and is apparently re- stricted to limestone and sandstone outcrops be- tween 950 and 1,150 m. REPRODUCTIVE BIOLOGY The members of sect. Quelusia all conform to a very similar pattern of floral biology. The flowers are hermaphroditic and self-compatible, as well as protogynous and herkogamous. Consequently, the enus has been characterized as crossing" (Raven, pendent, with the stigma exserted well below the anthers, a prime example of “approach herkoga- my” (Webb €: Lloyd, 1986), where the stigma is contacted as the visitor enters the flower prior to picking up pollen. Protogyny is incomplete, how- ever, because the anthers begin to dehisce within a day after anthesis, while the stigmas remain re- ceptive from the onset of anthesis until flower se- nescence several days later. Despite the presence of these outcrossing mechanisms, geitonogamous pollen transfer may still lead to effective selfing. Automatic selfing can also occur, since pollen usu- ally hangs down in clumps joined by viscin threads, which are able to contact the stigmatic surface before the flower senesces. The flowers of sect. Quelusia are highly spe- cialized for pollination by hummingbirds. Each species has red, odorless, hanging, tubular flowers with copious nectar secreted at the base of the floral tube, all standard features in hummingbird- pollinated plants (Faegri & van der Pijl, 1979). Unlike other bird-pollinated fuchsias, however, the petals are much larger and strongly convolute; they thus act functionally as a prolongation of the floral tube, further restricting the access of insects to the nectary. eep blue-violet color of the petals of sect. Quelusia is unique in the genus, althoug its significance in pollination is not clearly under- stood. The abundance of viscin threads in Fuchsia is among the most copious in the family and has been considered a probable adaptation to bird pol- lination (Nowicke et al., 1984) Hummingbirds are commonly observed visiting the flowers of sect. Quelusia throughout its native range, but few published accounts have identified the species of the hummingbird visitors. Curtis (1836) cited an early account by J. Anderson, the botanist on Philip King's voyage to the Magellan Straits, who observed numerous hummingbirds vis- iting F. magellanica around Port Famine, even after days of constant rain and sleet at near-freez- ing temperatures. Hauman-Merck (1912) reported frequent visits of Eustephanus galeritus (Mol.) on Volume 76, Number 2 1989 Berry 535 Fuchsia sect. Quelusia F. magellanica near Corral, in Valdivia, Chile. In Brazil, Ruschi (1982) reported Colibri serrirostris (Vieillot) visiting flowers of F. regia. A Plovercrest hummingbird, Stephanoxis lalandi (Vieillot), was observed visiting Fuchsia in the open campos area of Mt. Itatiaia, Rio de Janeiro state by Mitchell (1957), as well as by Ruschi (1982) in Teresopolis at 900 m. Three hummingbird species, Colibri serrirostris, j euco- chloris albicollis, were common around F. bra- celinae in the Serra do Caparaó, at 2,400 m, during a visit in February 1985 (L. Gonzaga, pers. comm.). It is unlikely that any strong pollinator discrimination exists between the different species ) flowers are very Stephanoxis lalandi, and of Fuchsia in Brazil, since the similar in size and overall floral pattern. On both F. campos-portoi and F. brevilobis, I have seen two different hummingbird species visiting flowers of the same bush in rapid succession, and I also watched an individual hummingbird visit flowers of F. brevilobis right after leaving flowers of a neigh- boring plant of F. regia subsp. serrae. Besides hummingbirds, several insect species have also been observed visiting flowers of sect. Quelusia in their native habitat. Apis mellifera was a common visitor to flowers of F. coccinea at Serra da Piedade, Minas Gerais, during our visit in February 1985; it was also observed on campos-portoi at Mt. Itatiaia in January 1985. Hauman-Merck (1912) described the visits of bus chilensis to F. magellanica in southern Chile, and thought it to be a more important visitor there than hummingbirds. Both of these bee species hang from the anthers to collect pollen and ma attempt to reach the nectary at the base of the tube; Bombus, especially, is able to make contact with the stigma and acts as an effective pollinator. I also saw a butterfly visiting F. regia subsp. serrae near Mogi das Cruzes, Sào Paulo, Brazil; it grasped the stamens attempting to enter the floral tube for nectar and made contact with both the anthers and the stigma in the process. When species of sect. Quelusia are cultivated outside their native range in areas where hummingbirds do not occur, such as England, they are frequently visited by honey bees and bumblebees (J. Wright, pers. comm.). Seed dispersal is probably effected by frugivo- rous birds, although no direct observations or pub- lished reports have been made. MORPHOLOGY Habit and stems. Plants of sect. Quelusia are all shrubs or lianas. Stems are usually flexuous and require the support of neighboring vegetation, but low, densely branched shrubs are common in such species as F. coccinea and F. bracelinae. Fuchsia regia can become a large, forest liana, with stems to 20 cm in diameter climbing as high as 15 m into the tree canopy, but it can also be found growing as a compact shrub in open situations. On large, climbing plants of F. regia and F. alpestris, it is common to find hanging branches several meters long. Short, divaricating side shoots are typical of young plants of F. regia subsp. serrae. Vegetative reproduction occurs in most taxa through stem-layering, especially when long, flex- uous stems lay over ground litter. Fuchsia bra- celinae and F. coccinea reproduce locally by un- derground, stoloniferous stems, and some populations of F. regia subsp. serrae ] roots on shoots well above the ground, as described by Lindley (1841) for F. radicans. aerial Leaves. Phyllotaxis in sect. Quelusia is op- posite or whorled. The most corumon condition in the section is ternate leaves, but individual plants often combine leaves in pairs, threes, and fours on different shoots. Exceptions are F. alpestris, almost always with opposite leaves, and F. regia subsp. reitzii, with leaves all in whorls of 3, 4, or 5. Fuchsia glazioviana has unusually short inter- nodes, just 3-12 mm long, with the leaves densely packed on the stems. The texture of the leaves of most species is membranous, but F. regia subsp. serrae has co- riaceous leaves, and those of F. regia subsp. regia are mostly subcoriaceous. Leaf surface is a useful character in some taxa; it is smooth and lustrous in F. regia subsp. serrae, with a dark green color above and a paler tone below. Leaf surfaces of Fuchsia glazioviana and F. hatschbachii are sim- ilar, but the surface is less brilliant. Impressed leaf veins are especially characteristic of F. bracelinae, and to a lesser M dii in F. brevilobis. Secondary venation in leaves of F. campos-portoi can be almost ds while in F. regia subsp. re- itzii a conspicuous tertiary venation is usually ev- ident. Leaf size and shape vary considerably within taxa, but some differences can be readily distin- guished. The leaves of Fuchsia glazioviana, F. bracelinae, and F. campos-portoi are small, most- y less than 4 cm long, and very narrow in F. campos-portoi. 'The largest leaves occur in F. al- pestris and F. regia subsp. regia and are mostly 6-14 cm long.

Quelusia subsp. reitzii they are conspicuously gland-serru- late, with the teeth angled towards the leaf apex. Fuchsia magellanica has mostly serrulate mar- gins, but they are sometimes crenate, with shallow lobes between the teeth. Petiole length is useful in discriminating taxa in sect. Quelusia. Fuchsia coccinea and F. brace- linae have nearly sessile leaves, with petioles 1—3 mm long, while they exceed 10 mm in F. regia subsp. regia and F. regia subsp. serrae. Often the proportion of the petiole to the blade length is very informative: high (> 1:4) in F. regia and F. mag- ellanica, and low (1:8 «) in F. hatschbachii and F. alpestris. Petioles are stout and over 1 mm thick in F. alpestris, F. coccinea, F. regia subsp. serrae, and F. regia subsp. regia; they are slender in F. magellanica. Stipules in all but one taxon are small, lanceo- late, and deciduous. Fuchsia regia subsp. serrae is unique, with prominent, persistent stipules that are thick and recurved, usually fused in pairs be- tween adjacent leaves, and give a characteristic nodose appearance to the stems. Flowers. in pairs in the axils of young leaves near the branch Flowers are all borne singly or rarely tips. Rarely more than two or three whorls of leaves bear flowers at the same time on a single stem. The pedicels are pendulous, except in F. coccinea, where they are divergent from the stem before hanging down in the distal half. Section Quelusia is the only group in the genus where the sepals are much longer than the floral tube. In addition, the sepals are always connate to varying degrees at their base, which in effect lengthens the tubular portion of the flower. The petals are strongly convolute and form a cone around the stamens and stigma. The nectary con- sists of a smooth to slightly lobed band ca. 1 mm thick lining the inner, basal portion of the floral tube. A flower from sect. Quelusia is illustrated diagrammatically in Figure 2. The floral tubes of most species are cylindrical- fusiform, but F. campos-portoi is distinct with its short, subrhombic tubes. Sepal connation is only -6 mm in most taxa. Fuchsia brevilobis is ex- ceptional, with sepals connate for 10-16 mm, al- most completely concealing the corolla and longer than either the free sepal lobes or the true floral tube. Fuchsia regia subsp. serrae also has sepals joined for over 4 their length; the buds are no- ticeably four-ridged, and the free lobes sometimes recurve after anthesis. Fruits. Berries in sect. Quelusia are generally oblong-ellipsoid and dark purple to black when ripe. n F. regia subsp. reitzii, the berries are mostly globose, while in F. magellanica they are much more elongate than in the other species. Ovules are biseriate in each locule and number between 60 and 120 per fruit. CYTOLOGY AND PALYNOLOGY Cytology. Concurrently with this revision, Hoshino & Berry (1989) made an extensive cy- tological survey of all 11 taxa of sect. Quelusia, examining 103 individuals from natural popula- tions and 11 cultivated plants. Their results showed the section to be entirely polyploid, predominantly tetraploid (n — 2x — ; i = 4x = 44) found in two species. All other sections in the genus, except for the tetraploid, monotypic sect. Kierschlegeria, are entirely or mostly diploid (n=x= 11). Tetraploidy was found in all specimens examined ut with octoploidy (n of six Brazilian species and in the more than 40 populations that were studied from the widespread F. magellanica of the southern Andes (see Hoshino & Berry, 1989, Table 1). Normal bivalent for- mation was observed in all of these collections. Octoploidy was limited to the three subspecies of F. regia and a single cultivated individual of F. alpestris. Fuchsia regia subsp. reitzii and F. regia subsp. serrae were consistently octoploid, but tet- raploid individuals were also found in F. alpestris and F. regia subsp. regia. In all octoploids ex- amined, varying numbers of quadrivalents were present at meiotic Metaphase I and Anaphase I. Although tetraploid and octoploid plants occurred sympatrically in several localities, no hexaploid in- dividuals were detected. The chromosome numbers of the individuals examined by Hoshino & Berry are indicated in this paper under the specimen citations of the respective taxa. Palynology. Pollen grains of Fuchsia have distinctive, onagraceous features such as viscin threads, paracrystalin e-spongy ektexine, protrud- ing apertures, and a solid endexine. The genus is unique, however, in possessing predominantly two- aperturate, bilaterally symmetrical pollen grains. Radially symmetrical, three-aperturate grains also occur in the genus but are confined to polyploid species and are clearly derived from two-aperturate ancestors, a result of the increased cell volume of polyploid cells. Most sections of the genus can be distinguished by a combination of aperture number, viscin thread ultrastructure, and t sculpture elements. Detailed pollen descriptions of the different sections are provided in Praglowski et al. (1983) and Nowicke et al. (1984) e of exine 538 Annals of the Missouri Botanical Garden The members of sect. Quelusia have radially symmetrical and three-aperturate pollen grains, a condition consistent with the polyploidy found in all species of the section. Viscin threads are seg- mented-beaded, and the exine has globular sculp- ture elements. Praglowski et al. (1983) reported a size range of 33-60 um for P (polar axis length) and 59-85 um for E (equatorial axis) for the seven taxa they examined. Rare four-aperturate grains have been found in F. coccinea and F. regia; occasional two-aperturate grains were also found in F. magellanica and were considered to be re- versions to the ancestral condition of the genus (Praglowski et al., 1983; Nowicke et al., 1984). Octoploid individuals of F. regia cannot be distin- guished from tetraploids by differences in pollen morphology, although octoploid pollen grains may be significantly larger (Hoshino, pers. comm.). he only other section of Fuchsia characterized by three-aperturate pollen is the monotypic sect. Kierschlegeria (F. lycioides). Its pollen can be distinguished from that of sect. Quelusia, however, by the smooth viscin threads with elongated sculp- ture elements (Nowicke et al., 1984). FLAVONOID COMPOUNDS Because of the ornamental appeal of Fuchsia, several studies have examined the role of antho- cyanins in the different flower colors in the genus (Harborne, 1963; Yazaki & Hayashi, 1967; Noz- zolillo, 1970; Yazaki, 1976; Crowden et al., 1977). Flower colors are determined almost entirely by the 3-glucosides and 3,5-diglucosides of all six com- mon anthocyanins. Red coloration in the sepals and floral tube is due mostly to cyanidin and peon- idin pigments, whereas the characteristic blue-vi- olet color of the petals of all members of sect. Quelusia is due to the dominance of malvidin de- rivatives, with peonidin in much lesser concentra- tions (Nozzolillo, 1970; Yazaki, 1976; Crowden et al., 1977). Yazaki (1976) indicated that the intense blue-violet color of some cultivars is due to the simultaneous presence of other co-pigments in the cell, particularly quercetin glycosides. In some cul- tivars, the petals change color from blue-violet to purple-red with age; Yazaki (1976) has shown this to be due to the combined effect of the flavonoid co-pigments, together with a decrease in the pH of the cell sap brought about by the accumulation of organic acids. Averett et al. (1986) carried out a comprehen- sive survey of the foliar flavonoids in 80 taxa of Fuchsia and reported the flavonoid profiles of four taxa belonging to sect. Quelusia. Current taxo- nomic changes in the section, however, have mod- nectary | floral tube insertion of sepal connation FIGURE 2. Schematic longitudinal section of a flower from Fuchsia sect. nee with terminology used in the species description ified these results, and a revision is presented in Table 1. Based on the same samples examined by Averett et al. (1986), two additional taxa are now included, F. brevilobis and F. regia subsp. serrae. From these changes, it is apparent that it is F. brevilobis, not F. regia, that has a distinctive fla- vonol diglucoside. Fuchsia magellanica remains the only species in the section known to possess flavones (compounds 12 and 15), which could be used as excellent markers for detection of the par- entage of this species in cultivars of uncertain or- igin, although flavones might not be expressed in all F. magellanica hybrids. Otherwise, the re- maining flavonol monoglucosides are all of common occurrence in other taxa of the genus. NATURAL HYBRIDIZATION Because of the restricted distributions of most of the Brazilian species of Fuchsia, there is no range overlap among them, except with the wide- spread F. regia. Fuchsia regia occurs sympatri- cally with five other species, and in eac morphologically intermediate, putatively hybrid in- dividuals have been detected (Table 2). Populations of F. regia subsp. serrae also occur together with each of the other subspecies of F. regia, forming extensive hybrid swarms in areas of sympatry. case, Volume 76, Number 2 Berry 539 Fuchsia sect.

Quelusia appears to occur readily, as there e only indication that reduced fertility might occur in hy- brids was from one artificial cross between a tet- raploid individual of F. regia subsp. regia and an octoploid individual of F. regia subsp. serrae, where the hexaploid progeny showed low pollen fertility (Hoshino & Berry, 1989). More experimental work is needed on the chromosomal behavior of crosses between tetraploid and octoploid taxa in sect. Que- lusia. In most cases, the area where two species over- lap is small, and the frequency or abundance of hybrids is low compared with the parental popu- lations.

Hybrids between these species and F. re- gia occur where they descend into the upper forest zone, or when F. regia extends beyond its normal limit into the open campos. Fuchsia brevilobis has the inverse of this pattern, generally occurring at lower altitudes than F. regia subsp. serrae, with probable hybrids in limited areas where their ranges overlap. Fuchsia bracelinae may have grown sym- patrically with F. regia until the past century, when extensive cutting and burning eliminated the upper forest belt of most of the Serra do Caparaó. The situation among the subspecies of F. regia is notably different. These taxa are much more widespread and overlap more extensively than any of the other species in the section. Fuchsia regia subsp. reitzii is typical of the planalto region in Rio Grande do Sul and southern Santa Catarina states, but it contacts populations of the more mesic F. regia subsp. serrae along the easternmost edge of the planalto near the crests of the Serra Geral, producing large, widely variable, intermediate pop- ulations.

Although F. regia is the only species presently found in widespread contact with other species of sect. Quelusia, the numerous hybrid combinations detected indicate that interspecific genetic recom- bination may have been an important mechanism in providing a rich source of novel, adaptive ge- notypes in the fuchsias of southern Brazil. EVOLUTION OF SECTION QUELUSIA Various lines of evidence, including chloroplast DNA restriction fragment analysis (Sytsma & Smith, 1988) and leaf flavonoid analyses (Averett et al., 1986), have suggested the Old World sect. Skin- nera to be the earliest offshoot of the genus and the sister group of all the American sections of Fuchsia. The oldest fossil pollen grains of the genus have been found in New Zealand and Australia from Oligocene and Miocene deposits (Pocknall & Mildenhall, 1984; Berry et al., in prep.). Despite the early divergence of this group, the members of sect. Skinnera exhibit several specialized fea- tures for the genus, including the derived condition of male sterility, reduced petals, presence of flavone sulphates, and a variety of unusual life forms, such as large trees and procumbent creepers. The most likely area of origin of Fuchsia is South America, where the greatest concentration of species as well as the sections with the most generalized features in the genus occur (Raven, 1979a; Berry, 1982). Whereas the large Andean sections appear to have arisen and radiated during the Neogene uplift of the tropical Andes (Berry, 1982, upied by sect. Quelusia have changed little since the mid-Ter- tiary, when temperate forests were much more widespread in southern South America (Simpson, 1973). With the current Australasian fossil record, it is now apparent that Fuchsia formed part of the 5) the areas now occ Nothofagus and podocarp-dominated temperate forests that occurred more or less continuously across southern South America, Antarctica, and Australia until at least the late Eocene (Zinmeister, 1987; Truswell, in press). The wet, temperate for- ests of the southern Andes and the montane forests of southeastern Brazil are now the only remnants of these austral temperate forests in South Amer- ica, which, like Fuchsia, share a large number of disjunct plant groups that also have close relatives in Australasia (Raven, 1979b) Although there are no fossil records to indicate an early presence of sect. Quelusia in South Amer- ica, the section follows a pattern consistent with other relicts of the southern temperate forests. It is ecologically conservative, with most individuals restricted to moist sites in cool, forest habitats. Morphologically, there is little divergence in the section, with species differentiated by relatively minor variations on a common pattern of floral and vegetative characters. Many of the features of sect. Quelusia are unspecialized in the genus, including the axillary, bisexual flowers, well-developed petals, numerous seeds, threads. It is possible that some of the primitive characters in sect. Quelusia were preserved throug and segmented-beaded viscin the buffering effects on evolutionary divergence caused by paleopolyploidy in the group (Stebbins, 1985; Hoshino & Berry, 1989) The ancestor of the modern-day species of sect. Quelusia was probably tetraploid, with derived, three-porate pollen (Hoshino & Berry, 1989). As such, it could not have given rise directly to the other, mostly diploid, sections of the genus, but rather represents an early offshoot of the ancestral stock of Fuchsia in South America. Early on, sect. Quelusia developed its own floral syndrome for hummingbird pollination: the relatively short, nec- tar-holding floral tube; large, attractive sepals; and petal cone and sepal tube that further extend the tubular portion of the blossom. Section Kierschlegeria, containing only F. ly- cioides restricted to the dry coastal scrub of central Chile, is the only other section of Fuchsia that is entirely polyploid and has three-porate pollen grains. Because of this similarity and its geographic prox- imity to F. magellanica, Berry (1982) and Raven 1988) postulated that it is related to sect. Que- lusia. Using chloroplast DNA restriction fragment analysis, Sytsma & Smith (1988) demonstrated that sects. Quelusia and Kierschlegeria form a distinct lineage from the rest of the genus, defined by three synapomorphies. Furthermore, within this — lineage F. lycioides could not be distinguished from the two species of sect. Quelusia studied, F. ma- gellanica and F. regia. This evidence of a close relationship is remarkable, since F. lycioides has a high number of specialized features, such as functional dioecy, spinose leaf bases, low seed num- ber, smooth viscin threads, small flowers, and sum- mer deciduousness. Evidently, the evolutionary shift of sect. Kierschlegeria to a xeric habitat in the southern Andes entailed a large number of mor- phological changes corresponding to a much small- er degree of genotypic divergence. Within sect. Quelusia, we are faced with the question of why there is just one species in Chile and Argentina, while in Brazil there are eight species Volume 76, Number 2 1989 Berry Fuchsia sect. Quelusia in an area of comparable size. Fuchsia magellan- ica is a classic example of the lack of differentiation that is characteristic of the /Vothofagus forests of Chile. These habitats presumably have been stable and continuous for long periods of time, providing little opportunity for speciation to occur. Most taxa inhabiting these areas have retained primitive char- acters for their respective groups (Simpson, 1973). Although the current distribution of F. magellan- ica extends beyond the Nothofagus forests, vir- tually all of the area now occupied by this species south of 44°S latitude was covered by ice during the Pleistocene (Vuilleumier, 1971) In contrast to the temperate latitudes of Chile and Argentina, the Brazilian members of sect. Que- lusia are centered in the subtropics. There, Fuch- sia is limited to the cool, moist habitats of the oastal mountains and the interior planaltos. Most of the cold-adapted taxa of Brazilian fuchsias are vicariant species that are now restricted to just a few high mountain peaks. Allopatric speciation in this group of species was likely enhanced by the joining and subsequent separation of populations caused by the cycles of Pleistocene glacial and interglacial events (Simpson, 1979; Klein, 1984). Two of the Brazilian species have adapted to warmer, lower-altitude habitats that are more con- tinuous over much of the southeastern part of the country. Fuchsia regia extends over the entire range of the section in Brazil and forms a broad taxonomic complex treated here as comprising three subspecies, each adapted to a slightly different set of environmental conditions. This species shows an intermediate stage in the morphological differen- tiation of populations between the more uniform F. magellanica in the southern Andes and the distinct, high-altitude species of Brazil. Fuchsia regia overlaps geographically with most of the other species in the section and hybridizes with them whenever they come into contact; these hy- brids may constitute an important source of genetic recombination for new adaptive genotypes in the section. It is also the only species in the genus with naturally occurring octoploid populations, which may lead to partial reproductive isolation with the other tetraploid taxa in the section. Two newly described species from Paraná, Brazil both consist of tetraploid populations that occur within the range of the octoploid subspecies of F. regia. The different ploidy levels may afford suf- ficient reproductive isolation for these species to remain distinct. One of the new species, Fuchsia hatschbachii, 1s the only species in the section that appears to be edaphically specialized, occurring on limestone and sandstone substrates on the eastern edge of the southern planalto. Populations of F. regia subsp. serrae occur within m of F. hatschbachii near Curitiba, Paraná, but the two have never been observed to grow together under natural conditions. The other new species, Fuchsia brevilobis, is specialized in its small flowers with elongate sepal tubes, and it has become adapted to lower altitudes than most neighboring popula- tions of F. regia. Overall, the evolutionary scenario of sect. Que- lusia differs significantly from the two, more spe- ciose, Andean sects. Fuchsia and Hemsleyella. Those species radiated recently into a broad ex- anse of new, cool montane habitats that were created with the recent uplift of the tropical Andes (Berry, 1982, 1985). Section Quelusia, on the other hand, has occupied a more ancient and stable vegetation type in which disruptive selection may have played less of a role in the divergence of populations. CLADISTIC ANALYSIS This section examines the relationships of the taxa of sect. Quelusia and the closely related F. lycioides by means of a formal cladistic analysis. The advantages of this approach are that it provides clearly stated hypotheses about evolutionary re- lationships based on shared, derived character states, and it is based on an objective, repeatable methodology. e data were analyzed on an ATT 6300 mi- crocomputer by the Wagner parsimony method of the PAUP software package (version 2.4.1., Swof- ford, 1985), using the branch and bound algorithm (Hendy & Penny, 1982). Character polarity was determined by outgroup comparison (Hennig, 1966; Watrous & Wheeler, 1981), using sect. Skinnera as the outgroup character states in sect. Skinnera are almost cer- . In two characters, however, the tainly apomorphic in the genus; so in these cases the other genera of Onagraceae were used as the outgroup. Twenty-two characters were used in the phy- logenetic analysis, with the character states listed in the data matrix (Table Fifteen equally parsimonious trees were pro- duced, each with 29 steps and a consistency index of 0.931. Topologically all the trees are identical, as they represent arbitrary resolutions of a single tetrachotomy that appears in the trees. The unique topology of these trees is presented in Figure 3. According to these results, sects. Kierschlegeria and Quelusia form a monophyletic group defined by five synapomorphies, but within this clade F. 542 Annals of the Missouri Botanical Garden Data matrix for characters of taxa used in the cladistic analysis of Fuchsia sects.

Section Quelusia is well delimited by the presence of four synapomorphies, and F. lycioides possesses eight unique, derived character states (autapo- morphies). Within sect. Quelusia, F. magellanica appears as the sister group of all the Brazilian taxa, which are grouped by a single character, loss of flavones. The Brazilian taxa of Fuchsia are poorly differentiated by the cladistic analysis, forming a polychotomy with four different lineages. Fuchsia hatschbachii is an isolated line in Brazil, differing from F. magellanica only by the loss of flavones. The three subspecies of F. regia form a separate, mainly octoploid lineage, supporting the monophy- crassate and persisten nt glabrous or sparsely pubsecent, 1 = parts of plant densely pilose mm, l = m ly of F. regia sensu lato. Fuchsia glazioviana and . campos-portoi are sister species within the third lineage. The fourth lineage includes four species, which are divided into two species pairs, the high- altitude F. bracelinae and F. coccinea, and F. alpestris and F. brevilobis. Two homoplasies (par- allelisms) occur in the cladogram: long-connate se- pals in F. brevilobis and F. regia subsp. serrae, and lianoid habit in two species pairs. The paucity of characters that discriminate be- tween the taxa of sect. Quelusia makes the results of the cladistic analysis within the section quite tentative, but it is also a reflection of the very close relationship of the species.

See Table 3 group relationship of F. magellanica to the Bra- zilian members of the section is consistent with the biogeography of the group and the evolutionary hypotheses discussed previously, specifically the southern origin of the genus in South America and the secondary radiation of the section in the high- lands of southeastern Brazil. According to this hy- pothesis, the Brazilian taxa differentiated, after their separation from the Andean F. magellanica, from an ancestor that had lost flavones. The occurrence of two parallelisms between F. brevilobis and F. regia subsp. serrae is remarkable and may be the result of past hybridization between the two species. HisTORY OF CULTIVATION Members of sect. Quelusia were by far the most important species used in the early stages of fuchsia breeding. For the most part, however, fuchsia breeders in the past century kept few records about the parentage of their introductions. As a result, it is impossible to determine with certainty which species have been involved in the parentage of most of the modern cultivars (Reiter, 1944). An- cestry of sect. Quelusia can be assumed in cultivars that share the following exclusive **quelusioid" traits: fairly large, axillary flowers with sepals equal to or longer than the floral tube, and large, violet, round- ed, and strongly convolute petals. Following Reiter (1944), one can distinguish three stages in the history of fuchsia breeding dur- ing the past century. First, a variety of species and natural varieties were accumulated in cultivation. different introductions from sect. Quelusia, and then in a more important step, these were crossed with Mexican and Central American species of sect. Ellobium. Some of the resulting strains were fur- ther crossed with species of other sections, such as F. boliviana (sect. Fuchsia) and F. lycioides (sect. Kierschlegeria). Although some other cross- than the quelusioid crosses. The final stage involved the exploitation and selection of mutations, which no longer depended upon the introduction of native material. In the remainder of this section, I will review the role of sect. Quelusia in the first two stages of fuchsia breeding, then summarize the present-day situation of sect. Quelusia species in cultivation. Species introductions. With the possible ex- ception of a short-lived introduction of F. triphylla in the early 18th century (Wright, 1975), F. coc- cinea was the first species of Fuchsia introduced into cultivation in Europe. Plants of this species were growing at Kew Gardens in London in 1788 (Aiton, 1789), and an illustration of it was published by Sims (1789). Hooker (1869) suggested that Sims’s figure might have represented F. magel- lanica rather than F. coccinea, because of the prominent petioles on the lower leaves. This is clearly not the case, however, as the figure ac- curately represents the unique arching pedicels and ovate, subsessile upper leaves of F. coccinea, and Sims's own specimen deposited at Kew is F. c cinea (pers. obs.). Although Dryander stated med the plants he described were introduced from Chile (Aiton, 1789), the species is native to just a few mountains in Minas Gerais, Brazil. The next introduction from sect. Quelusia was F. magellanica. An array of different variants of this species appeared in England in the 1820s 544 Annals of the Missouri Botanical Garden under several names, starting with F. gracilis, which was reported from the Edinburgh Botanic Garden in 1822 (Lindley, 1824). Fuchsia conica and F. gracilis var. multiflora were both intro- duced into England from Chile in 1824 (Lindley, 1827a, b). Fuchsia discolor was introduced from Port Famine in the Magellan Straits around 1830 (Lindley, 1835). I have seen no other evidence, such as old herbarium specimens from cultivated individuals, to indicate that F. magellanica was present in Europe prior to 1822. Soon after F. magellanica was introduced, however, it was con- fused with F. coccinea (see de Candolle, 1869 Fuchsia regia was first grown in England be- tween 1838 and 1840, under the name F. radi- cans (Lindley, 1841), and Fuchsia alpestris was cultivated in the Glasgow Botanic Garden as early as 1842 (Gardner, 1843). coccinea and was often cited as F. 1828, and Hooker, Interspecific crosses. Interspecific hybridiza- tion among members of sect. Quelusia must have begun in the mid-1820s, but the first evidence for this was the appearance of F. globosa in a Hor- ticultural Society exposition in London in 1832 (Lindley, 1833). Although the origin and parentage of this plant were not known to Lindley, the illus- tration and the description strongly suggest that it was a cross between F. magellanica and F. coc- cinea. A great proliferation of names of cultivars that were either variants of F. magellanica or crosses with F. coccinea followed in the next de- cades, including F. riccartonii, F. tenella, F. re- The history of these plants is unfortunately too poorly documented to curvata, and F. corallina. determine their precise parentage, and names such as riccartonii have been applied to quite different cultivated strains (J. Wright, pers. comm. A major step in the search for novel, interesting traits in Fuchsia cultivars was the use of F. fulgens, a diploid species of the Central American section Ellobium, in crosses with selections from sect. Que- lusia. One of the first such hybrids produced was exhibited in London in 1839, a cross of F. fulgens with F. globosa called “Standish's Fuchsia” (Lind- ley, 1840), which must have been either triploid or a spontaneously doubled hexaploid. Harrison (1841) also made a large number of crosses of F. fulgens with sect. Quelusia hybrids, publishing fig- ures of the flowers of several of the different hybrids he selected. A hybrid between F. cordifolia (— F splendens, sect. Ellobium) and F. globosa was grown in 1842, under the name F. exoniensis (Paxton, 1843). Fuchsia regia was also used in a series of crosses starting in 1840, leading to the development of darker petal color and improve- ment of flower shape (Wright, 1979). Fuchsia boliviana, a member of sect. Fuchsia from South America, may also have been used in the early crosses with selections of sect. Quelusia (J. Wright, pers. comm. ). he 19th-century crosses between members of sect. Quelusia and sect. Ellobium can be consid- ered the "mainstream" fuchsias later treated col- lectively under the names F. hybrida Hort. (Siebert & Voss, 1896; Munz, 1943) and F. speciosa Hort. (Bailey, 1900). In the strictest sense, these names have been attributed to crosses between F. mag- ellanica and F. fulgens. At the other extreme, they have been used to include almost all garden fuchsias. Reiter (1944) suggested that F. hybrida might best be treated as a horticultural complex including all cultivars of sects. Quelusia x Ellob- ium ancestry, including many of complicated ori- Chaudhuri (1956) made cytological observations that suggest how crosses between F. magellanica and F. fulgens might have facilitated the rapid advances in fuchsia breeding during the mid-1 800s. In his crossing experiments, the tetraploid (n — 2x — 22) F. magellanica and the diploid (n — x — 11) F. fulgens yielded triploid progeny in which a high percentage of unreduced gametes were pro- duced. As a result, the F, crosses were partially fertile, and hexaploids (6x) were produced in the F, generation, as well as tetraploid (4x) and pen- taploid (5x) individuals in the respective backcross- es. All of these crosses retained some degree of fertility. Crosses between F. magellanica and other diploids, such as F. splendens and F. denticulata, did not have the same propensity for unreduced gametes as F. fulgens, and their hybrids were large- ly sterile. Thus, F. fulgens may have been a critical species that helped prevent total sterility in crosses with the polyploid members of sect. Quelusia and with later cultivars of even higher ploidy levels. O. Wright in England has confirmed Chaudhuri's findings, producing a com- More recently, J. plete set of 3x to 9x progeny, entirely by selfing and backcrossing the original F. magellanica X F. fulgens hybrids (J. Wright, pers. comm.). Wright further reports that none of these hybrids showed any obvious similarity to F. fulgens. Fuchsia magellanica is the only species in sect. Quelusia able to withstand winter conditions with long periods of freezing temperatures, so that all of the hedge plants of fuchsia grown outdoors in England and Ireland are variants of this species or crosses with a strong F. magellanica parentage. Volume 76, Number 2 89 Berry 545 Fuchsia sect. Quelusia Many of the recent introductions from Brazil, how- ever, such as F. campos-portoi and F. coccinea, are proving to be frost-resistant as well (J. Wright, pers. comm. ). Native species in cultivation today. Many of the early species introductions have been main- tained for long periods of time in cultivation without crossing. Thus, Hooker (1869) was able to trace plants of F. coccinea found in the Oxford Botanic Garden in 1867 back to the original introduction of that species at Kew in 1788. Although this species may have been later lost from cultivation in England and Europe, it was successfully estab- lished on several of the Atlantic islands off the north African coast, such as Madeira, St. Helena, and the Canary Islands, in the early 1800s, per- sisting to present day (Hansen, 1969; A. Calero, pers. comm.). Plants of F. alpestris grown today in England and continental Europe have particu- larly small leaves similar to Gardner's type speci- men and may well date back to his original intro- duction in 1842. Wild strains of F. magellanica are apparently still present in England, and the species has become widely naturalized in parts of Ireland, New Zealand, Hawaii, South America, and eastern and southern Africa. As a result of the author's collections of native fuchsias in Brazil between 1985 and 1987, and seeds of different strains of F. magellanica ob- tained from Chile and Argentina, many new species and strains from sect. Quelusia have been recently introduced into cultivation. All the taxa recognized in this treatment, except F. bracelinae and F. glazioviana, are now in cultivation, with the most complete collections grown at the University of California Botanical Gardens at Berkeley and in the private garden of Mrs. Drude Reiman-Dietiker in the Netherlands. Other important collections include those of Mr. J. O. Wright in England, members of the different amateur fuchsia societies on the west coast of the U.S., and the Nederlandse Kring van Fuchsia-Vrienden in the Netherlands. SYSTEMATIC TREATMENT Taxonomic history. The earliest known spec- imens of Fuchsia from South America were col- lected in the Magellan Straits around 1690 by George Handisyd, who was surgeon aboard the British ship Modena (Middleton, 1909). These col- lections correspond to F. magellanica and are deposited in the eighth volume of Hans Sloane's herbarium at BM. Louis Feuillée published the first description and illustration of this species under the name Thilco (Feuillée, 1725), but it was not taken up by Linnaeus, who described Fuchsia in 1753 in Species Plantarum. More specimens of Fuchsia were collected in the Magellan Straits in January of 1768 by Philibert Commerson, natu- ralist on the French survey expedition led by Louis de Bougainville. Commerson's specimens were ex- amined by Lamarck, who designated them the type collection for F. magellanica, which he described in 1788. Another early collection of this species was made by Ruiz and Pavón between 1778 and 1788, near Concepción, Chile; they later described it as F. macrostema (Ruiz & Pavón, 1 ] Domingo Vandelli published the genus Quelusia in 1788, based on Brazilian plants. He did not name a species, and his description and illustration dealt mostly with the flower, making it difficult to distinguish which of the Brazilian species he was treating. José M. da C. Vellozo, a contemporary of Vandelli, described Quelusia regia from Brazil, providing locality information and an illustration that included leaves and flowers. Due to political problems, however, Vellozo's name for the species was not published until 1829 (Borgmeier, 1937; Carauta, 1973). Jonas Dryander described Fuchsia coccinea in 1789 based on cultivated plants that had been introduced in England the previous year. The source of his plants remains unclear, however, since Aiton (1789) attributed their introduction from Chile by a Captain Firth, while Salisbury (1791) stated that they were brought from Brazil by Vandelli around 1787. In reprinting Vandelli's publication of Que- lusia, Roemer (1796) added a footnote wherein he stated that Vandelli’s genus was the same as Dryander's F. coccinea. Meanwhile, Salisbury (1791) had already synonymized Quelusia under F. coccinea. In the first conspectus of the genus, de Candolle (1828) designated Quelusia as a section of Fuch- sia; by that time, the identity of F. magellanica and F. coccinea were already badly confused, and de Candolle considered them to be synonymous. Collections made in Brazil by Auguste de Saint- Hilaire between 1816 and 1822 resulted in the description of four new species by Jacques Cam- bessédes in 1830. None of these species have been maintained in the present treatment, but the name F. integrifolia Camb. was long used for F. regia. During the 1820s and 1830s, there was a sud- den surge of collections of Fuchsia from Brazil and Chile, and many plants were shipped for cultivation in Europe. Several new taxa, most of them now included under F. regia and F. magellanica, were described by John Lindley, George Gardner, and Karel Presl. During the second half of the 19th 546 Annals of the Missouri Botanical Garden century, Auguste Glaziou made extensive collec- tions in eastern Brazil, when this area was off limits to most foreign botanists. The rare F. glazioviana was described from one of his finds During the first half of this century, Curt Brade and Ynes Mexia collected fuchsias from the two highest peaks of southern Brazil, Pico da Bandeira and Itatiaia. Their collections led to the description of two local endemics, F. bracelinae and F. cam- pos-portoi. The leading figure in Fuchsia taxonomy was Philip Munz, who published a comprehensive re- vision of the genus in 1943. He refined the sectional concepts and limited sect. Quelusia to a closely knit group of species from Brazil and one from the southern, temperate Andes. He recognized five species in the section, as well as F. hybrida, which covered most of the cultivated hybrids. Two of his species were polytypic: F. magellanica had three varieties, and F. regia four. Since Munz, many new collections have accu- mulated, especially from the southern states of Brazil, where Balduino Rambo, Raulino Reitz, Rob- erto Klein, and Gert Hatschbach have made sig- nificant contributions. Their collections have led me to recognize four new taxa of Fuchsia from the south of Brazil in this treatment. During two field trips in 1985 and 1987, I was able to collect and study field populations of all the Brazilian taxa. In distinguish- ing species within the section, I attempted to rec- ognize basic, morphologically definable units that are also correlated with geographical, ecological, or cytological discontinuities between populations. It is assumed that these units also reflect the evo- lutionary divergences that have taken place in the group, but such hypotheses must be subjected to much more rigorous testing methods before they Criteria for taxonomic rank. can be substantiated. Subspecific rank was used when a wide-ranging species exhibited geographically or ecologically dis- tinct morphological variants, but these were linked by intermediate populations along localized areas of sympatr Although Jiri varieties have been recog- nized in the past for some species of Fuchsia, there is little biological basis for recognizing varieties. Similar pale color variants, for example, have ap- peared independently in a series of geographically distinct populations of F. magellanica, and they are probably the result of a single, recessive gene mutation (Chaudhuri, 1956). I do not consider this kind of variation worthy of formal taxonomic rec- ognition in a biosystematic revision such as this, although I do recognize the utility of assigning names to such plants for horticultural purposes. In widespread species, such as F. regia and F. magellanica, it has not been feasible to distinguish the genetic basis for the many minor variants that exist from environmentally induced variations or inherent plasticity in the plants. Most likely, ge- netically determined variations will best be rec- ognized through careful observation of plants cul- tivated under uniform growing conditions. In this way, amateur and professional nurserymen can make valuable contributions to our taxonomic un- derstanding of sect. Quelusia in the future, espe- cially if they maintain well-documented records of as porch of their stock and the constancy patterns of the different characters. E view of the uncertain phylogeny of the species of sect. Quelusia, they are listed as follows in alphabetical order. Fuchsia section Quelusia (Vandelli) de Candolle, Prodr. 3: 36. 1828.

Munz (1943) treated Fuchsia alpestris as a variety of F. regia, but the former can be readily distinguished from F. regia by having large, mostly opposite, short-petioled leaves. The older leaves have a characteristic subcordate base, and the en- tire plant has characteristic dense, pale pubes- cence. The flowers are considerably smaller and often much paler than those of the subspecies of F. regia that occurs in the same area. This species is rare in nature and is apparently confined to shrubby patches bordering exposed rock on the flanks of large, granitic domes. Fuchsia regia subsp. regia always occurs nearby, and some intergradation between the two species has been found at Pedra Dubois, near Santa Maria Madalena (see Appendix). 2.

Fuchsia bracelinae is distinguished from other members of the section by having dense, stiff pu- bescence and small, narrow, verticillate leaves. It inhabits only the rocky, open campos of the highest peaks of southern Brazil, in the Serra do Caparao. Individuals are found along rocks, in meadows, or in protected shrub and bamboo patches. This area is subject to frequent and severe winter frosts, and F. bracelinae is found to within 60 m of the 2,897- m-high summit of Pico da Bandeira. winter dieback of the above-ground stems probably accounts for the small stature of most plants, but underground stems lead to extensive vegetative reproduction in areas with good soil accumulation.

There are two dis- tinct areas where this species occurs, with notable morphological differences in their populations. In the low ramifications of the Serra do Mar in north- bescent, with especially long sepal tubes. Another group of populations is found on the lower, eastern flanks of the Serra do Mar in central Paraná, from 400 m to sea level. Most plants from these pop- ulations have longer petioles than those of higher altitude, and they vary considerably from popu- lation to population in color (dull pink to bright red), degree of sepal connation, and leaf shape and texture.

These plants grow as lianas and are found along rivers or streams, perhaps enabling them to withstand the heat and high evapotranspiration of the Atlantic lowlands. The population from Cacatu has unusually narrow, lanceolate leaves with acuminate tips. Throughout most of its range, this species is sympatric with F. regia subsp. serrae. The pres- ence of plants morphologically intermediate be- tween the two taxa indicates that hybridization has occurred between them (see Appendix). The pop- ulations of F. regia subsp. serrae in northern Pa- raná have exceptionally long sepal tubes, which may be the result of introgression with F. brevi- lobis. 4.

Fuchsia campos-portoi is readily distinguished from other fuchsias by its small and very narrow, gland-serrulate leaves. It also has unusual, small flowers; the floral tube is nearly rhombic and very short, whereas the sepals are up to four times as long and are noticeably inflated in bud. This species inhabits the high-elevation campos of the Itatiaia massif, where it grows in shrubby patches or in open, rocky sites. Winter frosts are common in this area. Populations of F. regia subsp. regia grow together with F. campos-portoi, and several intermediate plants have been found that indicate the occurrence of local hybrids (see Ap- pendix). 9.

The source of the plants is unclear; both Sims and FIGURE 9. Photograph of the lectotype of Fuchsia NN. coccinea from the Smith Herbarium at L Dryander described the species as a native of Chile, introduced to Kew by a Captain Firth. Salisbury (1791), on the other hand, stated that Vandelli introduced the species from Brazil around 1787. Fuchsia coccinea is a rare species known from just four of the highest mountain ranges in Minas Gerais. It typically grows in rocky, open campo or occasionally in forest patches. It has long been confused in the literature with F. magellanica, but F. coccinea is easily distinguished by its ovate, subsessile leaves with a conspicuous tuft of long hairs at the base of the lower surface. Its divergent or arching pedicels also differ markedly from the fully pendent flowers of the other species in the section.

Fuchsia hatschbachii is most likely to be con- fused with F. regia but differs by having shorter petioles, narrow leaves with somewhat curved pet- ioles, shortly connate sepals, and small stipules. It is tetraploid, whereas all examined populations of F. regia from Parana are octoploid. Fuchsia hatschbachii grows within 20 km of populations of F. regia subsp. serrae and F. brevilobis but occurs in drier, more interior areas of the planalto and is unusual in its close association with limestone or sometimes sandstone outcrops. The species is dedicated to Gert Hatschbach, Director of the seu Botánico Municipal de Curitiba, who has done more than any previous botanist to collect and study the flora of Paraná. 8.

Fuchsia magellan- ica lacks the long, drooping branches of some of the lianoid species from Brazil, and it generally grows as an upright shrub. In cultivation it can also reach treelike proportions and is considered the hardiest (most frost-resistant) of all Fuchsia species. A number of different species and varieties have been recognized by others for what is considered here to be a monotypic species. Two different color varieties have been named for plants that lack the typical red coloration of the floral tube, sepals, leaf 568 Annals of the Missouri Botanical Garden veins, and petioles. One, F. magellanica var. mo- linae, comes from the island of Chiloe; the other, F. magellanica var. eburnea, is from the southern Magallanes Region of Chile. Similarly pale-colored plants are also known from Corral, Prov. Valdivia, Chile (Gunkel 2133, GH). All of these plants occur sympatrically with red-flowered populations of F. magellanica and probably result from minor re- curring mutations on pigmentation. Munz (1943: 9) thought that plants from the southern part of the range, which he called F. magellanica var. typica, had consistently smaller leaves and flowers than those from the north, but this is clearly not the case. Large-leaved plants occur throughout the range of the species. James Solomon (pers. comm.) examined many local pop- ulations in Chile and Argentina and found that individuals growing in the sun usually have smaller leaves and flowers than those nearby in shadier sites. Similarly, clines in leaf size and texture occur along climatic gradients, such as that along the shores of Lago Nahuel Haupi in Argentina. The vegetation in that area becomes increasingly xeric from west to east, and plants of F. magellanica respond to this gradient by developing lower, more compact plants with smaller, thicker leaves. Populations of plants with small, densely packed leaves are common on the island of Chiloé, where high levels of humidity predominate throughout the year. Larger-leaved individuals also occur together with these variants. Some of the phenotypic vari- ants of F. magellanica may also be genetically determined, as they are known to maintain their distinctive characteristics under uniform growing conditions. In horticultural circles, there has been a strong tendency to assign varietal names to some of these strains. In this treatment, I am not recognizing any varietal or subspecific taxa under F. magellanica, because it is apparent that a great deal of local variation exists over the broad geographical range of the species, without any clear geographical cor- relations. The species is cytologically uniform, with over 40 populations counted with 2n — 44. Since most of the present range of the species, south of 44°S latitude, was completely glaciated during the major glacial advances of the Pleistocene (Vuilleu- mier, 1971), there has probably been very little time for populations to diverge in the southern part of the range. In his Flora of Tierra del Fuego, Moore (1983) cited localities of F. magellanica from as far south as the Beagle Channel at 55°S, and west to Staten Island, at 64°W. Collections from these areas were made in the past century, however, and it is un- likely that the species occurs there naturally today. According to D. Moore (pers. comm.), the intro- duction of goats on Staten Island early in the last century and the activities of Europeans in the vi- cinity of the Beagle Channel during the past 100 years have badly deteriorated the woody vegetation of these areas. On the drier, Argentinian side of the Andean Cordillera, F. magellanica occurs natively as far north as the Lago Quillen, at 39*30'S. Northwards, the mountains become increasingly arid. On the Pacific side of the Andes, native populations are found as far north as Concón (32°50'S), just north of Valparaiso. These populations grow close to the coast, along streams in wooded ravines. Looser (1928) found native populations of F. magellanica east of Santiago (33?30'S), in the Quebrada de Penalolén, between 1,450 and 1,750 m, and Navas (1976) reported the species from the nearby Que- brada de Macul. The northernmost extension of Fuchsia magel- lanica barely overlaps with the southernmost pop- ulations of the xeromorphic F. lycioides (sect. Kierschlegeria) in the vicinity of Concón, north of Valparaiso, Chile. A number of specimens col- lected in this area during the last century are morphologically intermediate between the two species and may represent interspecific hybrids (see Appendix). 9.

This is the most widely distributed species of Fuchsia in Brazil, occurring in the states of Minas Gerais, Espirito Santo, Rio de Janeiro, Sáo Paulo, Paraná, Santa Catarina, and Rio Grande do Sul from 18?20'S to 29°30'S Most common between 700 and 2,000 m, on the upper, wettest slopes of ranges such as the Serra do Mar, Serra Geral, Serra da Mantiqueira, and Serra do Espinhaço. Fuchsia regia subsp. reitzii is associated with the Araucaria forests of the southern planalto from Paraná to Rio Grande do Sul. Plants occasionally occur as high as 2,400 m on Mt. Itatiaia and at sea level in coastal restingas of Santa Catarina and Rio Grande do Sul. Flowers mainly from October to April. This is the most variable of the Brazilian species of sect. Quelusia. Three distinct and largely allo- patric series of populations can be recognized based on differences in several floral and vegetative char- acters. They intergrade in areas where their ranges overlap, and the presence of octoploid populations in some or all of the populations sampled in each series is unique in the genus. For these reasons, the different series are treated here as subspecies of F. regia. KEY TO THE SUBSPECIES OF FUCHSIA REGIA la.

Fuchsia regia subsp. regia is the most wide- spread of the Brazilian fuchsias, occurring in four different states, centered in Rio de Janeiro and Minas Gerais. As a result of its fragmented distri- bution, with populations in a number of discrete mountain ranges, considerable morphological dif- ferentiation has taken place throughout the range of this subspecies. It is also cytologically hetero- geneous, with tetraploid and octoploid populations. All counts made from Minas Gerais and northern Rio de Janeiro have been tetraploid, whereas oc- toploid and tetraploid individuals occur together in northern Sào Paulo and south-central Rio de Ja- neiro states, in areas such as Itatiaia, Serra da Bocaina, and Serra dos Órgáos (see fig. 9 in Ho- shino & Berry, 1989). The different cytotypes cannot be distinguished morphologically, however, and their relationships are not well understood. Fuchsia regia subsp. regia can be distinguished from other taxa of sect. Quelusia by having large flowers with spreading sepals and only slight sepal connation, large leaves with petioles generally long- er than 10 mm, and mostly glabrous stems and foliage. This subspecies has a particularly broad ecolog- ical tolerance, extending from tall cloud forest at 1,000 m to open campos as high as 2,400 m. When it occurs inside the forest, F. regia subsp. regia grows as a liana, flowering when its branches reach sufficient light in the tree canopies. As the vegetation decreases in height with greater ele- vation, it grows as a scandent shrub, and as a short, erect shrub when found on the edges of the open campos. This gradual transition in the habit of subsp. regia has been observed in several localities, such as the Serra dos Órgãos and the Morro da Nova Caledônia in Rio de Janeiro, and the Serra do Itacolomi and Serra do Itambé in Minas Gerais. As a result of its broad altitudinal and geograph- ical distribution, F. regia subsp. regia occurs sym- patrically with four other species from sect. Que- lusia. In each case, morphologically intermediate individuals have been found that indicate the oc- currence of interspecific hybridization (see Appen- dix). It also occurs sympatrically with F. regia subsp. serrae in northern Sào Paulo along the eastern slopes of the Serra da Bocaina, where it forms hybrid populations, with further intergra- dation southwards along the Serra do Mar as far as Caraguatatuba. These populations are discussed in the Appendix. Several collections of F. regia subsp. regia from widely distant localities are unusually pubescent yet do not appear to be the result of hybridization or introgression with pubescent species growing nearby, such as F. alpestris or F. coccinea. The specimen Campos Porto 3421 (RB, from Campos do Jordáo, Sào Paulo, 1,600 m) is similar in all morphological features to nearby glabrous popu- lations of F. regia, but the entire plant is covered by a dense, pilose indumentum. Three collections from Minas Gerais are similarly pubescent: Gard- ner 4555 (K), Claussen 88 (G), and Brade 16953 RB, US, from the Serra do Caparaó). Martinelli et al. 169 (RB, Vale das Videiras, Petrópolis, Rio de Janeiro) is covered by short, fine pubescence, which is unusual among the populations of F. regia from Rio de Janeiro. These pubescent variants are apparently quite rare, and none were found ~ during my fieldwork in Brazil. 9b. Fuchsia regia subsp. serrae P. Berry, subsp. nov. TYPE: Brazil. Paraná: Mun.

Quelusia besides F. brevilobis with the sepals connate for over one-third of their length. It is unique in its persistent, crassate stipules and lustrous, subcoriaceous leaves with thick petioles. Unlike the other subspecies of F. regia, the sepals are usually recurved at anthesis and four-angled in bud. This subspecies is most common along the crest and upper slopes of the ' the steep and very wet region on the eastern edge of the southern Brazilian planalto as it drops abruptly to the At- lantic coastal plains. The rugged terrain, with sheer “serras, drops o m or more, such as those found in the Aparados da Serra in northern Rio Grande do Sul, creates a broad diversity of microhabitats re- flected in the large degree of variability in different populations of this subspecies. For example, low, densely branched subshrubs characteristically grow in rock crevices on the steep drop-offs of the Apa- rados, while tall lianas with long, drooping branches are found in more protected, forested areas near the crest of the Serra. The degree of sepal connation varies consider- ably in different parts of the range of F. regia subsp. serrae. In northern Paraná, where it occurs together with the long-tubed F. brevilobis, the se- pals are often joined for half or more of their length. Along the Serra Geral in southern Santa Catarina and Rio Grande do Sul, however, the sepals are less joined than populations further north; in ex- treme cases, individuals like Falkenberg 3744 and 3745 have the sepals joined for only 4-6 mm, but their thick, shiny leaves and nodose stipules are characteristic of subsp. serrae. ong the edge and just inland from the steep drop-offs of the Serra Geral in Rio Grande do Sul Volume 76, Number 2 1989 Berry 577 Fuchsia sect. Quelusia and southern Santa Catarina, a sharp ecotone oc- curs between the drier, flatter planalto and the wet, steep coastal slopes. In this area, Fuchsia regia subsp. serrae occurs sympatrically with the east- ernmost populations of Fuchsia regia subsp. re- itzii, and the two subspecies intergrade extensively in areas such as Itaimbezinho, Serra da Rocinha, and the edge of the Serra Geral near Uribici and Bom Jardim da Serra in Santa Catarina. Further discussion and a list of intermediate, probable hy- brid individuals between these two subspecies is found in the Appendix. Towards the northern limits of the range of Fuchsia regia subsp. serrae, this subspecies also contacts populations of Fuchsia regia subsp. regia, especially in the Serra da Bocaina in northern Sào Paulo state. Populations of subsp. serrae predom- inate there on the lower, coastal slopes below 1,100 m, while subsp. regia occurs at higher elevations and further inland. Extensive intergradation be- tween these two subspecies occurs on the upper coastal slopes of the Serra, where unusually pilose individuals are also found. Some of these individuals are octoploid, as in all the southern populations of subsp. serrae, while others are tetraploid, like some of the populations of subsp. regia from the Bocaina range and further north (Hoshino & Berry, 1989). Although F. regia subsp. regia reaches its southern limit at the Serra da Bocaina, populations of Fuch- sia with mixed ploidy levels and dense pubescence occur south of the Bocaina area as far as Ubatuba in the Serra do Mar of north-central Sao Paulo state (Hoshino & Berry, 1989). Fuchsia regia subsp. serrae also occurs sym- patrically with F. brevilobis in several localities in Paraná. Although F. regia is octoploid in this area, and F. brevilobis is tetraploid, the occurrence of be d intermediate individuals indicates at hybridization has taken place between these taxa (see Appendix). The unusually long sepal tubes of populations of F. regia subsp. serrae in this area are characteristic of F. brevilobis and may be the result of introgression with this species. Outside of its typical montane habitats, F. regia subsp. serrae has also been found in coastal res- tingas at sea level, near the Rio Grande do Sul- Santa Catarina border. Reitz (1961) first detected this apparent anomaly in the distribution of typi- cally montane taxa, and found it to occur in at least ten other species that normally occur along the crest of the Serra Geral. The presence of these species in the restingas must represent recent chance introductions from the nearby serras, as the coastal plains of this area are only of Quater- nary age (Klein, 1984). 9c.

Compared with F. regia subsp. serrae, the only other Fuchsia that grows near populations of subsp. reitzii, the sepals are much less joined and spreading (instead of recurved), the stipules are much less prominent, the leaf bases are more acute, and the berries are rounder. This subspecies is named in honor of P. Raulino Reitz of the Her- bário Barbosa Rodrigues, Itajai, Santa Catarina, who has made great contributions to the knowledge of the flora of Santa Catarina. Subspecies reitzii is restricted to the planalto west of the coastal mountain ranges of southern- most Brazil. Its overall distribution in this area parallels that of Araucaria angustifolia, although it does not tolerate the shade of the dense conifer forests. Both species extend as far east as the edge of the coastal escarpments but end abruptly there 580 Annals of the Missouri Botanical Garden and do not appear on the seaward slopes or in the lower, coastal forest (Hueck, 1953 Along the eastern edge of the planalto, where sharp drop-offs usually occur down to the Atlantic lowlands, the range of F. regia subsp. reitzii over- laps with F. regia subsp. serrae, which extends up from the moist, coastal slopes of the serras. A great deal of intergradation and variation exists in the Fuchsia populations of these areas, especially at the crest itself and just inland of the steep drop- offs. In some instances, the extreme local variability is indicative of hybrid swarms, while in other sites, odd variants are found that can extend beyond the normal limits of variation of either subspecies (see Appendix). A number of unusually pubescent individuals, usually with conspicuously tan or ferrugineous hairs, occur in populations near the southern and western extremes of the range of subsp. reitzii in Rio Grande do Sul. Collections from the Farroupilha area, such as Rambo 45781, 45782, and 40172 and Ca- margo 980, are uniformly pubescent, while others, such as Rambo 31024 from Vila Oliva near Ca- xias, and Rambo 51576 from Passo do Socorro near Vacaria, occur together with more typical le individuals of the subspecies.

Fuchsia lycioides belongs to a different section, Kierschlegeria, and differs widely gellanica in its small, alternate leaves, spinose leaf bases, smaller flowers with included stamens and reflexed sepals, and generally occurs in much drier habitats. Both species are tetraploid (Hoshino & Berry, 1989) and have been shown to be closely related by chloroplast DNA restriction site analysis (Sytsma & Smith, 1988). The ranges of the two species barely overlap in the hills around Valpa- raiso, where several natural hybrids were collected in the early 1800s. These plants are characterized by small flowers with larger, convolute petals than those of F. lycioides. The leaves are larger and more often opposite than in F. lycioides, with the characteristic dentation of F. magellanica. They also lack the spinose leaf bases typical of F. ly- cioides. The natural habitats where the early hy- brids were collected have probably been totally eliminated by urban growth. Hybrids of these two species appear quite often in cultivation and have sometimes been confused . ma- with the true F. lycioides, as in the cytological study of Chaudhuri (1956). 2. F. regia subsp. regia X F. alpestris Specimens examined. BRAZIL. RIO DE JANEIRO: dada Dubois, Santa Maria Madalena, Santos Lima & Bra 14240 (B, RB); Plowman & de Lima 12885 (F, M Both parental species occur locally on Pedra Dubois; the specimens cited above are intermediate in their short, fine pubescence, petiole length (6— 10 mm), and flower size (floral tubes 10-12 mm long). 3. F. regia subsp. serrae X F. brevilobis BRAZIL. SAO PAULO: Reserva iguel Arc- MBM). PARANÁ: 13 Specimens examined. Carlos Botelho, between °, Lange train station and Prainhas, 310 m, Cordero et a in 16 Jan. 1987 (MBM; n = 3 Fuchsia brevilobis is sympatric with F. regia subsp. serrae over most of its range but usually grows at lower elevations. These taxa are unique in the section in having their sepals connate for more than one-third of their length, but F. brevi- lobis has more membranous leaves that are nar- rower, shorter-petioled, and more pubescent than F. regia subsp. serrae, while the latter has more prominent, persistent stipules. The flowers of F. regia subsp. serrae also differ from F. brevilobis in their four-ridged buds, glabrous, nitid surface, and flaring sepal tube. The intermediate individuals cited above are from three different localities where the parent species are locally present. In the Ca- pivari locality, the same hummingbird was observed visiting flowers of both species in succession. Further experimental work on artificial hybrids of these two taxa is desirable, since only tetraploid counts have been obtained from F. brevilobis, and all individuals examined of F. regia subsp. serrae have been octoploid (Hoshino & Berry, 1989). The count obtained from Cordeiro et al. in 16 Jan 1987 was tetraploid, indicating that it may only be a variant of F. brevilobis, and that of Berry et al. 4448 was octoploid, as found in F. regia subsp. serrae. 4. F. regia subsp. regia X F. campos-portoi Specimens examined. BRAZIL. RIO DE JANEIRO: Ita- tiaia, just above Hotel Brocken-Holsene, road to Abrigo Rebougas, 2,340 m, Berry et al. 4440 (MO, RB; n = red oe Agulhas Negras, Lanstyak 253 (RB #61360). Fuchsia campos-portoi is endemic to the high- altitude campos of Mount Itatiaia and is very dis- tinctive in its small, narrow, strongly serrate leaves and small, short-tubed flowers. Fuchsia regia is common in forests at lower elevations on the same mountain range and occurs together with F. cam- pos-portot in thickets near the treeline above 2,200 m. Both specimens cited above are intermediate in leaf size, number of secondary veins, and floral features, such as the ratio of tube to sepal lengths. Meiosis in buds of Berry et al. 4440 was normal, with the same chromosome number as recorded in local parental populations. 5. F. regia subsp. regia X F. coccinea cimens examined. BRAZIL. MINAS G ERAIS: Serra r (n — 22), 4547, 4548 (MO, RB); Falkenberg 3380 (FLOR); Mello Barreto 9168 (R); Serra da Caraga, Mello Barreto 7157 MH). Fuchsia coccinea typically grows in thickets amid the rocky, open campo of the highest peaks in Minas Gerais. On the Serra do Itacolomi, fire has destroyed much of the woody vegetation on the highest slopes; F. coccinea is now very rare in that area, and intermediate forms with F. regia are common. In the series of Berry 4545-4550 and Falkenberg 3380-3387, some of the individ- Volume 76, Number 2 1989 Berry 583 Fuchsia sect. Quelusia uals were treated under F. coccinea, but several of them show signs of introgression with F. regia, such as leaves that are larger or more coriaceous and rounder-based than individuals of isolated pop- ulations of F. coccinea. The collections cited above are clearly intermediate between the two species in key characters, such as petiole length, degree of leaf pubescence, and leaf shape. Both species are tetraploid in this locality, and the one hybrid examined cytologically was tetraploid with normal bivalent formation. Both species are also known together from the Pico do Itambe, farther north in the Serra do Espinhago. Although the collections of Anderson et al. 35832 and Furlan et al. 3058 were treated under F. coccinea, they both have unusually thick leaves for that species, as well as rounded rather than cordate leaf bases; these traits may be t result of introgression with sympatric populations q) of F. regia. 6. F. regia subsp. regia X F. glazioviana Specimens examined. BRAZIL. RIO DE JANEIRO: Mor- ro da Nova Caledônia, outskirts of Nova Friburgo, 1,810- 1,950 m, Berry et a 4427 (MO, RB), 4429 (RB), 4430 (MO, RB; n = 22). As in the previous two cases, F. glazioviana is a local, high-elevation endemic that is sympatric with F. regia near the former's lower altitudinal limits. Fuchsia glazioviana has small, densely packed leaves and smaller, narrower flowers than F. regia. Most of the hybrids were found along roadsides in cleared areas, and one large patch of variable individuals was seen in an exposed area near the upper limit of the cloud forest. Local populations of both species are tetraploid, as was the one intermediate individual counted. 7. F. regia subsp. serrae X F. regia subsp. regia Specimens examined. BRAZIL.

Populations of F. regia subsp. serrae and subsp. regia converge and intergrade extensively on the upper, seaward slopes of the Serra da Bocaina, close to the Rio de Janeiro-Sào Paulo border. Fuchsia regia subsp. regia reaches its southern- most limits in the Serra da Bocaina, occurring mostly at altitudes of 1,100-1,550 m on both sides of the Serra. Fuchsia regia subsp. serrae occurs exclusively on the lower, seaward slopes of the same range between 500 and 1,150 m, part of an almost continuous distribution down the coastal slopes of the Serra do Mar and Serra Geral as far as Rio Grande do Sul. Varied intermediate forms between the two sub- species occur between 1,150 and 1,350 m on the upper slopes of the Serra da Bocaina, along the road from Cunha to Paraty. Most of the fuchsias in this area, including those cited in the above list, are unusually pubescent for F. regia. The degree of sepal connation and the thickness and persis- tence of the stipules, which generally distinguish these taxa, vary widely between individuals in this area, whereas populations higher up on the Serra and further inland are largely glabrous and fall well within the normal range of variation of F. regia subsp. regia. Hoshino = Berry (1989) reported duals of Fuchsia from tetraploid and octoploi this area, further ee the intergradation of the basically octoploid subsp. serrae and the mostly tetraploid subsp. regia. Hexaploid hybrids should be sought in mixed populations. Although F. regia subsp. pae is not found a popra ations of ove Ubatuba ap- proximately 60 km south of e Bocaina massif. Tetraploid and octoploid individuals occur side by side at the Alto da Serra near the crest of the mountain (Hoshino & Berry, 1989), again with the unusual pubescence for F. regia and considerable variability in such traits as the degree of stipule development. In most other features, however, these individuals resemble F. regia subsp. serrae more closely than subsp. regia. 8.

Both of these two subspecies are morphologically and ecologically distinct over most of their ranges, with F. regia subsp. reitzii confined to thickets in the southern planalto and F. regia subsp. serrae inhabiting the wet, seaward slopes of the coastal mountain ranges. Fuchsia regia subsp. serrae has nitid, subcoriaceous leaves with thick stipules and flowers with strongly connate, recurved sepals, while subsp. reitzii has thinner, more whorled leaves with serrate margins, thin stipules, and flowers with spreading, slightly connate sepals. À narrow ecotone occurs all along the crest of the Serra do Mar and the Serra Geral in Santa Catarina and Rio Grande do Sul as the high rolling plains end and the steep coastal ranges drop abrupt- ly to the Atlantic lowlands. Along this belt, which occurs sometimes just at the crest of the ridges and other times extends a few hundred meters or several kilometers inland, the two subspecies of F. regia converge and intergrade in a bewildering variety of variants, some of them exceeding the normal limits of variation of either parental sub- species. The narrowest ecotone observed was at the Serra da Rocinha, on the Santa Catarina- Rio Grande do Sul border. In this area, the planalto is covered right to the edge by grassy campos, followed by steep drop-offs covered by a special “Aparados” flora adapted to the persistent rains and mists from the rising coastal air masses (Rambo, 1956). Along the rim of the serra cliffs, between 1,250 and 1,280 m, hybrid swarms of F. regia subsp. serrae and reitzii occur together with occasional plants that can be distinguished as parental, such as those included in the collection series of Falkenberg et al. 3756-3766. Other areas where similar series of intermediates have been observed and collected include the Apa- rados da Serra at Itaimbezinho, in Rio Grande do Sul, and the area around the crest of the Serra Geral between Bom Jardim da Serra and Lauro Müller in Santa Catarina. Near the town of Urubici, Santa Catarina, plants of F. regia subsp. serrae occur farther inland from the crest of the Serra Geral, around the base of the Morro da Igreja and Campo dos Padres, the highest points in Santa Catarina. Where the two subspecies occurred sym- patrically, as in the collection series of Falkenberg et al. 3787-3791 (FLOR, MO; just W of the crest of the ridge between Urubici and Brago do Norte, at 1,030 m), some unusual variants of subsp. ser- rae were found with flowers less than half the normal size (43790). oth subspecies are octoploid and are charac- terized by variable numbers of multivalents during meiotic metaphase (Hoshino & Berry, 1989); the one intermediate individual examined had the same chromosome number and type of meiotic config- uration. OBSERVATIONS ON POLYPLOIDY IN FUCHSIA Takuji Hoshino? and Paul E. Berry? (ONAGRACEAE)! ABSTRACT Chromosome numbers are reported for all eleven taxa currently recognized in Fuchsia sect. Quelusia and for F. lycioides, the sole member of sect. AS Results are based on the study of individuals from 103 native populations and 13 cultivated plants. Most species and sections of Fuchsia are diploid (n = x = 11), but sects. Quelusia and Kierschlegeria are entirely de ba including the only naturally occurring octoploids in the genus. Polyploidy in these sections is always associated with 3(4)-aperturate pollen grains, instead of the normal 2-aperturate condition in the genus. All ona counts obtained from F. lycioides and from seven of the nine species in sect. Quelusia were tetraploid, but intraspecific variation in ploidy level was found in two Brazilian species of sect. Quelusia. The only wild individual examined of F. alpestris was tetraploid, whereas a cultivated specimen of this species from urope was octoploid. In the widespread, polytypic F. regia, all individuals examined of subspecies reitzii and serrae were octoploid, but both tetraploid and octoploid populations were found in subsp. regia. Both ploidy levels were also d in the extreme northern range of subsp. serrae, in individuals that were morphologically intermediate with . This situation suggests that octoploidy has evolved recently and possibly repeatedly in s sect. Quelusia, whereas tetraploidy probably originated in a common ancestor to sects. Quelusia and Kierschlegeria. Fuchsia is one of the largest genera of the Onagraceae, with over 100 species occurring most- ly in tropical montane cloud forests. It is placed in its own tribe, Fuchsieae, on the basis of its fleshy fruits and mostly 2-aperturate pollen. Chromo- somes in Fuchsia are large and are heterogeneous in size for the family, with interphase nuclei having ycnotic areas that are variable in number, size, and density (Kurabayashi et al., 1962); these are unspecialized features shared with Lopezia and Circaea. All species examined in the genus have the basic chromosome number of the family, x — 11 (Raven, 1979), and none have the translocation systems or aneuploidy that are characteristic of other onagraceous genera such as Oenothera and Clarkia. In recent efforts to improve our understanding of the relationships of the different species and sections of Fuchsia, the distribution of chromosome numbers has been determined for as many species as possible in the genus, together with extensive surveys of the palynology and foliar flavonoid chemistry of most taxa (Nowicke et al., 1984; Averett et al., 1986). To date, diploid chromosome counts (n — 11) have been obtained for 69 species and tetraploid counts (n = 22) for 10 species (Breedlove, 1969; Breedlove et al., 1982; Berry, 1982, 1985; Berry et al., 1988; Hoshino & Berry, 1988). Of the ten sections currently recognized in the genus (Berry et al., 1988), six are entirely diploid. The two largest sections, Fuchsia ( species) and Hemsleyella (14 species), are pre- dominantly diploid, but sect. Fuchsia has six known tetraploid or partly tetraploid species (Berry, 1982), and sect. Hemsleyella has two tetraploid species (Berry, 1985).

The only previous reports on chromosomes in sect. Quelusia were from F. magellanica. The first report by Warth (1923) was n = 22 for F. coccinea, but photographs in a subsequent publi- cation (Warth, 1925) showed that this was a mis- identification of F. magellanica. Johanssen (19292, b) reported diploid counts of n = 11 for two hor- ticultural selections of F. magellanica, but no vouchers or illustrations were provided to verify the identity of his plants, which were very likely misidentified (P. Raven, pers. comm.). A report of n — 44 in F. magellanica by Haque (1952) also lacked vouchers.

Although Chaudhuri (1956) reported a tetraploid count for F. lycioides, no voucher specimens were provided, and his de- scription of this entity clearly indicates that it was a hybrid, probably of F. magellanica x F. ly- cioides parentage. MATERIALS AND METHODS Meiotic chromosomes were examined in pollen mother cells of young buds fixed in Carnoy's so- lution (3:1 absolute ethanol to glacial acetic acid) for 24 hours, then transferred to 70% ethanol for storage. Anthers were squashed in 1% aceto-or- cein. Somatic chromosomes were studied in root tip apices, which were pretreated in 0.002 M aqueous 8-hydroxyquinoline for 6 hours at 5?C, then fixed 6.

The root tips were stained in 1% aceto-orcein for 10 or 20 minutes and then squashed. To establish pollen fertility, pollen grains were stained with Alexander's solution (Alexander, 1969). RESULTS Chromosome counts from 40 different popula- tions of native and cultivated individuals of F. ma- gellanica were consistently tetraploid (n — 22; Table 1, Appendix). The populations sampled cov- ered most of the range of this widespread species of southern Argentina and Chile, leaving little doubt that it is cytologically uniform throughout its range. Counts of all other taxa in sect. Quelusia rep- resent their first validated chromosome reports (Ta- ble 1). Seven Brazilian species, including the newly described F. brevilobis and F. hatschbachii (Ber- ry, 1989), are all tetraploid, based on at least two counts for each species.

Normal bivalent formation was found in all tetraploid col- lections examined (Figs. 1-4). In the Brazilian F. alpestris, the single naturally occurring individual counted was tetraploid, but a plant of this species cultivated in Europe was octoploid. Fuchsia regia, the most widespread species of the genus in Brazil, has tetraploid and octoploid populations (see Appendix). Populations from the southern half of its range were entirely octoploid, including all populations counted of subspecies reitzii and serrae and one naturally occurring hy- brid between them. In most of the octoploids, nu- merous quadrivalents and bivalents were formed (Figs. 5-8). Populations of F. regia subsp. regia with both tetraploid and octoploid individuals were found in northern Sào Paulo and southern Rio de Janeiro states (Appendix, Figure 9). The southernmost tet- raploid individuals of F. regia came from north- central Sào Paulo State. These collections are morphologically intermediate, probable hybrids be- tween subspecies regia and serrae. They also occurred sympatrically with octoploid individuals Volume 76, Number 2 1989 Hoshino & Ber ry Polyploidy in Fuchsia FicunES 10, 11. serrae (2n = 88) (Ramamoorthy & Hatschbach 830 e (2n — 66), artificial hybrid between Ramamoorthy 6 ru regia, 2n — 4 Photomicrographs of pollen grains viu Fuchsia sect. n ies Fuchsia regia subsp. x F. regia subsp. serrae .

Scale bars = 150 u of F. regia subsp. serrae, but no hexaploid indi- viduals were found in these areas. In Minas Gerais and other parts of Rio de Janeiro, all populations of subsp. regia sampled were tetraploid. The dis- tribution of the different cytotypes of F. regia is shown in Figure 9 Although meiosis was not observed in an artificial hexaploid hybrid between a tetraploid plant of F. regia subsp. regia and an octoploid one of subsp. serrae, more than 50% of the pollen grains of the hybrid were aborted. Both parents, however, showed fully era and apparently viable pollen grains l (Figs. DISCUSSION Sections Kierschlegeria and Quelusia are the only entirely polyploid sections of Fuchsia. In both groups, polyploidy is associated with 3-aperturate pollen, considered to be derived from the more common 2-aperturate condition in the genus (Now- icke et al., 1984). Despite differences between the two sections in viscin thread type (Nowicke et al., 1984), seed number and anatomy, sexual systems, and other morphological features (Berry, 1982), a preliminary chloroplast DNA restriction site anal- ysis by Sytsma & Smith (1988) has shown the two sections to be more closely related to one another than to any other section of the genus. The results of a separate cladistic analysis of the species of these two sections by Berry (1989) were consistent with the hypothesis that tetraploidy evolved in a common ancestor. Since the other eight sections of the genus are predominantly diploid, e the South Pacific sect. Skinnera and al zen- tral American sections, it is clear that no exiis member of sect. Quelusia or sect. Kierschlegeria could have directly given rise to those groups. Octoploidy in natural populations of Fuchsia is known only in sect. Quelusia, where it has been detected primarily in F. regia, a species that also has tetraploid populations. Quadrivalents are com- mon in the octoploid individuals examined, indi- cating a close chromosomal homology between the genomes that came together. Both the presence of different ploidy levels and the varying numbers of multivalents in F. regia indicate a recent origin of octoploidy in the genus. Whether the octoploidy detected in F. alpestris originated naturally or 590 Annals of the Missouri Botanical Garden under cultivation is not known, but the extent of the two different chromosome numbers needs to be examined further in nature. Cases of intraspe- cific polyploidy are widespread in the Onagraceae and have been recorded in over 40 species and 11 genera (Lewis, 1979). The high level of pollen abortion in the artificial hexaploid between a tetraploid and an octoploid subspecies of Fuchsia regia is indicative of irreg- ularities in meiotic pairing and disjunction, which may explain the absence of naturally occurring hexaploids among the individuals sampled in areas where tetraploids and octoploids both were found. Areas where tetraploid and octoploid populations of F. regia are known to occur sympatrically, such as the Serra da Bocaina and Campos do Jordào in northern Sao Paulo state, and the Itatiaia massif and the Serra dos Orgaos in Rio de Janeiro, should be sampled more intensively for naturally occurring hexaploids. Within the Onagraceae, the pattern of poly- ploidy in Fuchsia sect. Quelusia is most similar to that of Ludwigia, where polyploidy has been a frequent and important part of the evolutionary strategy in most of the genus, with numerous cases of intraspecific polyploidy (Raven & Tai, 1979). Unlike the situation in tribe Onagreae, where poly- ploidy is associated with autogamy and aneuploidy in annual species, aneuploidy is unknown in Fuch- sia and Ludwigia, and polyploid taxa are perennial and predominantly outcrossing. This clearly shows that the effects of polyploidy can vary widely in related genera, depending on factors such as the longevity of the species and the habitat in which they occur.

NOTES ON THE CORDIA PANAMENSIS COMPLEX (BORAGINACEAE) AND A NEW SPECIES FROM COLOMBIA Cordia is a large pantropical genus of about 300 species, divided by most recent authors into six sections (Nowicke & Miller, in press). Section Myxa, with over 150 species, is the largest in the Neotropics and includes all but one of the paleo- tropical species (Miller, 1985). It is difficult tax- onomically because most of the groups that can be recognized within the section have obscure bound- aries. One such group is the Cordia panamensis Riley group (Miller, 1985), which is widespread in Cen- tral America, the West Indies, and northern South America. This group is particularly problematic in terms of its definition. within sect. Myxa, as well as species delimitations within it. It is loosely de- fined and may very well not be monophyletic, yet the species all share a similar appearance and are often confused in herbaria. The C. panamensis group is characterized by ovate to nhe sca- brous to scabrid, usually anisophyllous leaves that generally dry brown. All of the species except C. anisoph ylla J. S. Miller are dioecious. Perhaps C. bicolor A. DC. and C. sellowiana Cham. should be included, but C. bicolor does not dry brown, and both species differ in being homostylous. Sculpturing on the surface of the endocarps KEY TO THE SPECIES OF THE CORDIA PANAMENSIS GROUP appears to be useful in distinguishing species of Cordia sect. yet been used e this. Dried fruits of various species of the C. panamensis group were soaked in 5% NaOH for two days to soften the exocarp and mesocarp, then washed in running water to remove yxa (Miller, in prep.) but has not outer tissues and expose the cleaned, outer surface of the endocarp. Cordia gentryi has an endocarp with raised, quadrangular areas (Fig. 1C); in C. anisophylla the raised areas are much longer (Fig. 1 D). Other members of the group have rugulose (C. panamensis, Fig. 1E) to spinulose (C. Aebe- clada I. M. Johnston, Fig. 1F) endocarps. Recent studies of members of the C. panamensis group have helped clarify the relationships of species in Central America (Miller, 1985, 1988) and Ven- ezuela (Gaviria, 1987). The group is defined here as consisting of ten species, but problems still exist with differentiating C. panamensis and C. macro- phylla. | have seen little material of C. macro- phylla and have maintained it as separate following Johnston (1949). As part of a review of the panamensis group, several novel collections from Pacific coastal Colombia appear to represent an undescribed species. la. Leaf apices acute to obtuse. 2a.

NOTES A NEW ASPIDOGYNE (ORCHIDACEAE) FROM VENEZUELAN GUAYANA The genus Aspidogyne Garay is one of the recent segregates from Erythrodes Bl. (Garay, 1977) and comprises 27 species, widely distributed in the American tropics, primarily Brazil. They are small to medium-sized terrestrial, humicolous, to (rarely) subepiphytic herbs growing in mostly shady places of rain or cloud forests. Aspidogyne belongs to the pantropical subtribe Physurinae, of seven genera. Among them, As- pidog yne can be recognized by the following com- bination of features: horizontal stigmata; elongate, erect column; and entire emarginate rostellum. A revision of the Aspidogyne species of the Venezuelan Guayana for the orchid treatment in Steyermark's Flora of the Venezuelan Guayana has revealed a different identity for the species that appeared in Foldats 70) as Erythrodes picta (Lyndley) Ames, a synonym of 4spidogyne ar- gentea (Vell.) Garay. Foldats had already noted that the Venezuelan material cited under £. picta differed from the type, and suggested that it might represent a new variety. New evidence shows that the differences are sufficient for recognition of a new species, described below. Aspidogyne steyermarkii Carnevali & Foldats, sp. nov. TYPE: Venezuela.

The genus is well known to gardeners in the United States, Europe, and New Zealand, since the species and cultivars are widely grown in shady gardens for their attractive foliage and flowers (Aden, 1988). They are also grown as ornamentals and eaten cooked in China, Japan, and Korea. Traditionally Hosta has been placed in the Liliaceae (e.g., Cronquist, 1981) or in the Funkiaceae (Dahlgren et al., 1985) along with Hesperocallis A. Gray and Leucocrinum Nutt. ex A. Gray, both from western North America. Bailey (1930) and Stearn (1931) noted that Hosta is a taxonomically difficult genus with con- fused nomenclature. Although a number of papers have been published on Hosta during the past 50 years, there has been little improvement in our understanding of the genus. The matter has been largely complicated by broad (Fujita, 1976) or narrow (Maekawa, 1940) species concepts and confusion caused by cultivars. The plants have relatively few good diagnostic features that can be observed in pressed and dried herbarium specimens (Hylander, 1954). In an attempt to improve our knowledge of Hosta, my associates Carleen Jones, Myong Chung, and Haynes Currie and I have been attempting to assemble a collection of living hostas. Several years ago Barry R. Yinger, then of the U.S. National Arboretum, supplied seeds of several accessions of Hosta collected from Taehuksan Is- land, a remote island off the southwestern coast of orea. Examination of my cultivated plants and field-collected vouchers at NA reveals a new species, named in honor of the collector, Barry Yinger. Hosta yingeri S. B. Jones, sp. nov.

TAEHUKSAN ISLAND: garden-grown material of same collection as holotype, Yinger et al.

Hosta yingeri is distinct from other species of Hosta in its relatively thick, adaxially dark green leaves. This feature may be an adaptation to its coastal habitat, growing at 2-60 m above sea level. It is also distinguished by its delicate raceme of flowers spread evenly around the central axis of the inflorescence; typically, Hosta has subsecund racemes. An additional diagnostic feature of H. yingeri is the exceptional length of the second set of stamens, with both sets exserted well beyond the perianth. Our living material has been compared with representative accessions of all species of Hos- ta in our garden and with loans of herbarium ma- terial. Hosta yingeri is an attractive and interest- ing new species with horticultural potential. It appears to be associated with Maekawa's (1940) subgenus Bryocles, section Tardanthae. Hosta yingeri does not resemble our garden-grown ma- terial of H. tsushimensis obtained from the Na- tional Arboretum. LITERATURE CITED ADEN, P. id The Hosta Book.

Rhizome rather short-creeping, 1.5-2.5 mm diam.; scales fuscous, small, narrowly triangular with broad base, acuminate, ca. 1 x 0.2 mm, ca. 8-seriate at base. Leaves a few-several mm apart; petiole usually lustrous, atropurpureous to black, smooth but the basal part bearing some small wart- like bases of shed scales: adaxial (sometimes also abaxial) side flattened (near the apex) to faintly sulcate, abaxial side otherwise rounded; length ca. 12-22 cm, equaling the lamina to much exceeding it. Lamina narrowly oblong, ca. 10-20 cm long, paucijugate-bipinnate, or a few once-pinnate or subbipinnate sterile leaves present beside the bipin- nate fertile ones; primary rachis dark reddish to blackish brown, abaxially faintly biangular to dis- tinctly sulcate. Pinnae from 1 odd one to more often 1—3 pairs and a conform terminal one, mod- erately to very strongly ascending, hence the width of the lamina quite variable; lateral pinnae with a petiolule of ca. 8 mm, 7-10(-16) cm long, up to 15 mm wide, somewhat narrowed near the base, gradually and strongly tapering to the apex. Sec- ondary rachises medium to dark brown, dull, adax- ially sulcate, the groove bordered by rounded ridges, abaxially subacutely biangular. Pinnules close to contiguous or even overlapping, coriaceous, often blackish when dry, dull or adaxially sublustrous, dimidiate, spreading or somewhat ascending, up to ca. 25 well-developed ones to a side, above these some much-reduced pinnules, a few finally con- fluent into a short, pinnatifid pinna-apex. Larger pinnules ca. 6-9 mm long, 3.5-5 mm wide, about 1.5 times as long as wide, semiovate to subtrian- gular, base cuneate, posterior margin straight or convex, anterior margin approximately straight, entire or more often distantly and shallowly incised to ca. 0.5 mm, the lobes flanking the incisions mostly touching to overlapping, thus the incisions inconspicuous. Inner margin of pinnules straight, diverging from the rachidule, an outer margin not developed; all margins, especially the posterior, sclerotic, apex subacute to obtuse but not rounded. Sterile pinnules very shallowly and rather irregu- larly crenate. Veins immersed but somewhat evi- dent, adaxially often slightly impressed in dry spec- imens, free, simple or the inner forked above the base, ca. 5-8 vein-ends per pinnule present. Sori occupying the anterior margin, interrupted, or in small pinnules continuous, (1-)2-5 per pinnule, each on 1-4(-6) vein-ends, ca. 1.5-4 mm long; indusium firm, entire, often somewhat undulate (not sinuate!), about equaling the margin, ca. mm wide.

Volume 76, Number 2 1989 Notes 607 1,800 and 2,800 m. The species is often described as being locally common. The interrupted sori were at first taken for an abnormality due to incomplete fertility of the leaves, as is often seen in the genus. The constancy of the character, however, leaves no doubt about its being a distinctive feature of the species. Lindsaea mesarum resembles L. stricta (Sw.) Dryander var. jamesoniiformis Kramer in habit, but this is certainly due to convergence. The two taxa occur in the same habitat and are sometimes collected next to each other. The closest relative of L. mesarum is L. klotzschiana Moritz ex Et- tingsh., which has thinner, much more pronounced- ly incised pinnules and larger rhizome scales. Another probable relative is L. parkeri (Hooker) Kuhn subsp. steyermarkiana Kramer, a little- known taxon of somewhat uncertain status; it has thinner pinnules that are much less narrowed to- wards the apex. If the inconspicuous incisions of the anterior margin of the pinnules of L. mesarum are overlooked, it will key out to £. stricta (Sw.) Dryander in the present author's key (Kramer, 1957); from this it can be distinguished by its smaller rhizome scales, and the forms of L. stricta with dark leaf axes have strongly rounded pinnules. The author is indebted to the Curators of the Herbaria MO, NY, and UC for lending and/or donating material, and to Mr. A. Zuppiger, Zürich, for preparing the illustration. LITERATURE CITED o K.

This small and inconspicuous passionflower is known from four areas of lower montane rainforest in Costa Rica. Passiflora nubicola grows at edges of primary forest, in treefalls, or along trails, where its thin wiry dark green stems trail over fallen logs and among grasses, bushes, and small trees. The leaves are similar in shape to those of a juvenile P. biflora Lam., and their flecks of white varie- gation are similarly distributed. The flower also resembles that of a miniature P. biflora, but in the Orosi valley possesses only one row of coronal filaments. The species is closely related to P. bi- ora. At the Monteverde Reserve, the main herbivore of this species is Heliconius clysonimus (J. Mallet, pers. comm The clone on the same plant as the holotype of this species was grown at Duke University 1977- 1983, and the chromosome count was determined from the clones of this plant. Floral anthesis was around 0830 hrs. in the greenhouse, with the flow- ers closing in the early afternoon. No fruits were set by autogamy during cultivation, and more than 40 attempts at self -pollination also failed to produce fruit. Passiflora nubicola was very fertile in both directions with P. biflora (MacDougal 260GR & 275GR), yielding well-seeded fruit and vigorous F, progeny. Those progeny, generally morphologi- cally intermediate in vegetative and reproductive character states, had variously malformed flowers and were sterile, producing no viable pollen. Fruits (with hybrid embryos) produced on P. nubicola matured in 45-48 days and contained 35-64 seeds per fruit (N — 13 fruits). The epithet means *'cloud-dweller," to its habitat of misty forest. in reference Passiflora gilbertiana MacDougal, sp. nov. TYPE: osta Rica.

It is a member of a species group of Central American passionflowers in section Decaloba char- acterized by bilobed variegated leaves, greenish to yellow perianth, filiform unbanded outer coronal filaments, and notable reduction in the size of the petals relative to the sepals. This group is part of section Decaloba but was not recognized by Killip (1938), who scattered its component species among of section Decaloba. several of his invalid *'series" Within the group, the new species is most closely related to P. jorullensis H.B.K. of Mexico, P. apetala Killip of Costa Rica and Panama (Fig. 3), and an undescribed relative of P. apetala from the mountainous border of Mexico and Guatemala. Its distinctive characteristics include its long nar- row leaf with a relatively small interlobe angle and more strongly expressed red to purple coloration, retention of conspicuous laminar variegation at ma- turity, and yellow flower with small petals and second (inner) series of coronal filaments. The inner series of coronal filaments varies as to presence or absence within the species. In Taylor & Skotak 4771 the series is well developed, numbering ca. 40; in the type it is absent. However, the cultivation of somatic clones (MacDougal 655) from the type plant revealed that the expression of the second Volume 76, Number 2 89 Notes 613 FIGURE 3. 368). — B.

Passiflora apetala (MacDougal 467).— 0). —B. apetala, flower only (MacDougal 45 filamentous series was variable within this individ- ual, with (0-)5-12(-20) filaments per flower. The expression changed gradually along the stem, at times stronger, at times weaker, perhaps dependent on environmental conditions. In certain cases the expression seemed to be related to the position of the flower on the vine, with smaller flowers near the end of flowering axillary branches completely lacking the second series. On the label of the type is the collector's note "odor of pigpen." The flowers of this new species share this strong odor (described as between “ster- coraire et putride" by Planchon, 1849) with P. jorullensis (pers. obs.). Gilbert also noted on the type label **visited by hummingbirds,” but the same day he also observed a single wasp flower (pers. comm.). It is thus probably significant that P. jorullensis, with a nearly identical odor, is pri- at a marily wasp-pollinated at least in some part of Mexico (MacDougal, unpubl.). The habitat at the type locality is treefalls and partially shaded thickets along a dirt road on steep slopes in the lower reaches of Alnus forest. Plants there climbed over bushes and trailed into small Alnus and Piper trees. An important herbivore at the type locality is a yellow flea beetle that is an Comparison of leaves and flowers of three closely related species. — A. Passiflora Dino (MacDougal — D. Passiflora undescribed species of Monomacra (from Mac- Dougal 1431, voucher identified by C. Duckett, deposited in the Cornell University Insect Collec- tion). Several of the cited specimens show char- acteristic damage by flea beetles. A clone from the type collection was cultivated at Duke University and from there was distributed to several commercial greenhouses in California and made available for sale to the public by 1980 In cultivation the plant bloomed from the morning to afternoon, with anthesis around 0930 hrs. and flower closing in mid to late afternoon. The stigmas, although lowered to anther level into the afternoon, were not receptive after ca. 1230 hrs. No fruits were set by autogamy during cultivation, but during limited hand-pollinations, 6 of 11 self-pollinations before 1230 hrs. produced mature fruit containing 19-31 seeds per fruit. Mr. Patrick Worley, a commercial plant hy- bridizer, crossed a clone of the type with P. biflora, P. ornithoura Masters (MacDougal 623), and P. jorullensis (MacDougal 368); many F, progeny were grown to maturity and all flowered. Pollen viability was not examined. In each case the un- pleasant odor was conserved. One especially or- namental individual of the cross with P. jorullensis 614 Annals of the Missouri Botanical Garden was named *'Sunburst" and has been available to the public from several nurseries since 1983. I take great pleasure in naming this species for its discoverer, Lawrence E. Gilbert of The Uni- versity of Texas at Austin, whose seminal contri- butions to the understanding of the ecology of the Passifloraceae and their herbivores are well known. Dr. Gilbert first suggested the study of passion- flowers to me and has aroused and guided an in- terest in these plants in many other students. It is particularly gratifying to name this plant because had the privilege of being with Dr. Gilbert the day he discovered it and gathered the type collec- tion. He immediately suspected it to be undescribed and his exuberance kindled in me what has become a career. Many of the observations given here were made at Duke University, and I gratefully acknowledge Donald E. Stone for his inspiration and guidance during my graduate studies. Thanks are due the Organization for Tropical Studies for their summer field course that introduced me to Lawrence Gilbert and to these Costa Rican passionflowers. The staff of the Duke University greenhouses provided many years of favorable conditions for passionflower vines, and the Jessie Smith Noyes Foundation generously provided postdoctoral support for research on this family at the Missouri Botanical Garden. The draw- ings were prepared by John Myers. LITERATURE CITED ISCC-NBS (Inter-Society Color Council — National Bu- The American species of Passi- loraceae, Publ. Field Mus. Nat. Hist., Bot.

Seed of P. mayarum (Téllez & Cabrera 2429). western Belize, and the southern part of the Yu- catán Peninsula (Fig. 2). The collections come from elevations of 20-250 m, except for two collections from one station at 550 m in Belize. The habitat is usually open or partially open vegetation. Al- though the information is not present on the spec- imen's label, Bartlett (1935: 20) stated that his collection 12840 was collected in the wooded swamp vegetation called escobal, which is a vegetation type dominated by the escoba palm, Cryosophila. This edaphic climax occurs in the Petén and Yu- catán on wet soil surrounding water holes (““agua- das") and as the transitional zone between the inundated areas of the w and the well-drained **high bush” uplands (Bartlett, 1935; Lundell, 1937). However, most of the col- lections are from disturbed and more well-drained habitats, namely, roadsides and secondary areas in low forest, selva mediana subperennifolia, or sel- va alta subperennifolia (Rzedowski, 1978). Phenology. The few collections known sug- gest that reproduction occurs primarily during the wet season from April through November. One sheet, however, was collected in flower at the end of December. Although the type has nearly mature fruit, fully mature fruit and seeds are known only from Téllez & Cabrera 2429. “Granadilla” (Tún O. 372). Vernacular name.

Except for the vestiture, the two have similar leaves and nearly identical glandular bracts. At the time of his 1938 monograph, Killip knew Passiflora prolata only from the type. He knew the related species newly described here from a single collection by Bartlett (12840). He had iden- tified that sheet as P. prolata (Killip, 1936), but later expressed some misgivings. In his monograph (1938: 389) he stated, “I am referring the Bartlett collection to P. prolata with some hesitation, as the stem and under surface of the leaves are pu- berulent and the petiolar glands are not quite as in the type. It comes, moreover, from the low- lands." The more recent collections of both species confirm that the two are separate morphologically and ecologically. Neither fruit nor seeds are known from P. prolata, so it is impossible to compare the two species on these points. They may be distin- guished by the following key. la. Stems and leaves glabrous except for slight pu- e h long, acuminate. Petioles glandular i in the distal half, the glands 0.3-0.8 mm diam. and usually longer than wide. [da lobes conspicuously ng-acuminate; laminar rulate, often t the junction of the petiole. Bracts glabrous abaxially. Hy m an als glabrou Habitat idu 700-2,000 m ooo... P. prolata _ c un er O d un pf a] a P - berulent. Stipules 10-22 mm long, long-atten- uate. Petioles glandular at a variable position, the glands 0.7-2.2 mm diam. and wider than long. Laminar lobes acuminate to short-caudate; laminar margin uniformly serrate (to serrulate), not nectariferous at the junction of the petiole. Bracts puberulent abaxially. Hypanthium pu- berulent, sepals puberulent or only sparsely so. Habitat elevation 20-550 m „u P. mayarum Not having seen the type of P. prolata (Leh- mann 1630—G-BOIS), I have relied on the pro- tologue and five more recent collections, including one of my own, that match the protologue. Three of these collections were identified as P. prolata by Killip (who saw the type), and one was collected within 30 km of the type locality at a similar elevation. The flowers of P. prolata and P. may- arum appear to be rather similar, apparently borne above the horizontal plane, with two prominent series of purplish outer coronal filaments, several reduced intermediate series, and a well-developed inclined inner series. The operculum in both is similar, although that of P. mayarum has shorter subapical filaments. I have seen the flower of P. prolata only from Matuda 16479 (F), in which the intermediate coronal series are reduced to var- iably expressed series of tubercles. It is not possible to determine clearly the relative length of the two outer series except to say that they are roughly similar in this poorly pressed specimen. Given the lack of comparative reproductive material and the coronal variation that occurs within related species, I have for now distinguished the two species mainly by vegetative characteristics. he leaves of P. mayarum tend to be less deeply lobed, but there is considerable overlap with P prolata. The quality and quantity of the indument differ: the few trichomes that occur on the leaves and nodes of P. prolata are ca. 0.2-0.4 mm in- stead of 0.05-0.25 mm long. Despite the variation in their vestiture, the bracts of both species always have a narrow band of dense tomentum along the margin adaxially. The trichomes are crispate, and those of adjacent bracts are interlocked during the development of the bud, keeping the bracts valvate. This marginal band of crispate tomentum occurs in number of species of Passiflora and is correlated with foliaceous valvate bracts. The ovary of mayarum is glabrous in all collections exiled except Tün O. 1374, in which it is sparsely pu- berulent. Some of the Mexican collections of the new species were distributed as P. platyloba Killip and are cited as such in Sousa & Cabrera (1983). Passiflora mayarum and P. prolata belong to subgenus Passiflora, where they share character- istics with species that Killip (1938) included in his informal *'series" Serratifoliae and Incarnatae. 618 Annals of the Missouri Botanical Garden Killip placed P. prolata next to P. incarnata L. as one of six species in /ncarnatae, which was MSE n = Passiflora (as sub- nus “Granadilla”) as having unwinged stems, free te narrow stipules, lobed leaves, eglan- dular sepals, filamentous corona in more than two series, petiolar glands present, and denticulate or fimbriate operculum. That delineation is fraught with difficulties since most of those character states are undoubtedly plesiomorphic for the subgenus. Except for the lobed leaves, it also fits the species put in the Serratifoliae group. An understanding of the relationships among these species and the granadillas as a whole awaits a revision of subgenus Passiflora. Passiflora mayarum is probably ge- netically close enough to the commercially impor- tant P. edulis Sims to warrant investigation into using it as a rootstock or as a source of genetic rovement for the commercial passionfruit. It is especially notable that P. mayarum has been col- lected growing in warm wet soil, the kind of con- ditions that induce fungus-related failure of the commercial crop The epithet mayarum refers to the native dis- tribution of this species, centered in the heart of the Mayan Old Empire I am grateful to the Jessie Smith Noyes Foun- dation for postdoctoral support for research on passionflowers, to the curators of the herbaria listed above, and to John Myers for the drawing.

Both are members of sect. Tournefortia, a pantropical group with its center of diversity in Andean South America. Species of Tournefortia from this area remain con- fused, since the most recent taxonomic treatment available is de Candolle's (1845). Macbride (1960) covered the species from Peru, but his treatment is regional and incomplete. Killip prepared an un- published treatment of the Andean species. The following two species are new.

Flowers bisexual, with the stigma borne beneath the anthers; sepals 5, free to the base, linear-lanceolate, 3-5 mm long, unequal in length, densely brown strigose; corolla white, tubular with 5 spreading lobes, 5 mm long, the lobes ovate, 1 mm long, the tube 4-5 mm long, brown strigose, densely so near the apex, sparsely so near the base; stamens 5, the anthers borne just beneath the mouth of the corolla tube, nearly sessile, ellipsoid, 0.8 mm long; ovary ovoid, ] mm tall, the style 3 mm long, the stigma conical. Fruits unknown. Tournefortia brantii is a member of sect. Tour- nefortia and belongs to a group of about 10 poorly defined species that have opposite leaves. These species occur from Costa Rica through Colombia, Ecuador, Peru, and into Bolivia and are centered in the northern Andes. While problems exist with species delimitation among the opposite-leaved species of Tournefortia, T. brantii is distinct among the South American species by having dark brown indument and sepals to 5 mm long. It is most similar to T. johnstonii Standley, a species of Panama (Miller, 1988), which differs in having sepals longer than 6 mm and a corolla tube 8-10 mm long. The other species of Tournefortia with opposite leaves in Colombia, 7T. pauciflora Nowicke and T. sca- brida Kunth, differ in having shorter calyces and less prominant indument on the twigs (Nowicke, 1974).

A NEW SPECIES OF URGINEA (LILIACEAE) IN NIGERIA The genus Urginea Stein. is represented i in | West Kunth, U. ensifolia (Thonn.) Hepper, U. pauciflora Bak., and the variable U. altissima (L.) Bak., which was recently discovered to resolve into a complex of three species: U. altissima (L.) Bak., sensu stricto, U. gigantea (Jacq.) Oyewole, and U. viridula Bak. (Oyewole, 1975). Samples of wild populations continue to reveal the inadequacy of the existing taxonomy of the genus. For instance, complexes such as in U. indica (Oyewole, 1987) or entirely new variants are being discovered. Hence, a revision of the genus is due. The present report describes a recently discov- ered wild population of a new species within the main campus site of the University of Ilorin, Kwara State, in west central Nigeria. EcoLoGY The flora of a rock outcrop located about 1.5 km to the east of the academic area of the main campus site of the University of Ilorin, about 20 km outside the city of Ilorin, was first sampled in May 1982. The site of the rock was to be part of a proposed botanical garden. About 100 tiny bulbs of an evidently new rep- resentative of Urginea were collected between May 1982 and February 1983, from the shallow soils of the outcrop. The soil is brown and lateritic, with occasional dark humus in depressions. The vege- tation is low grassland, with few small trees of Entada africana, Erythrina pulcherrima, and other legumes interspersed with stands of Butyro- spermum paradoxum and Lophira lanceolata, and low stands of Cochlospermum sp. Herbaceous species of Commelinaceae and Asteraceae are com- mon among low grasses. Seasonal marshes and ponds support the growth of various Cyperaceae, Anthericum nigericum, and many low, herbaceous Acanthaceae and Scrophulariaceae. ulbs of U. nana occur in an unshaded area with low grass and forb cover. Other bulbous geo- phytes occurring in the same habitat and inter- spersed with U. nana are Dipcadi tacazzeanum (Hochst. ex A. Chev.) Bak. (D. filamentosa Mor- ton) and Pancratium hirtum A.

These bulbs resemble U. pauciflora in being few-flowered, and the depauperate morphs of U. indica in having linear-lanceolate, stiffly erect leaves and few-flowered inflorescences. They differ, how- ever, in the form and width of the vegetative leaf, and in the size of the scape and the positioning of the flowers on the inflorescence. Examination of the herbarium specimens at the Herbarium of the Forest Research Institute of Nigeria (FHI), Ibadan, and at the University of Ibadan Herbarium (UIH) revealed that such specimens have not been col- lected previously in West Tropical Africa. Earlier examination of materials at Kew also showed that specimens of this taxon have not been recorded. Certain variations were observed in the floral and vegetative morphology, on the basis of which the population was segregated into three morphs designated A, B, and C. This informal categori- zation was necessary for the purposes of karyotypic examination and eventual cytogenetic studies. Morph A. Bulbs ovoid-spherical, 3-4 cm o” $ > ^ FIGURE 2.

Tepal greenish with hyaline margin, 6-7 mm long, about 1 mm broa The floral dimensions of the three morphs over- lap so that they are not easily distinguished, but morph C differs distinctly in vegetative morphol- ogy. Plants of U. nana must have escaped rec- ognition for so long because of their habit of growth: the fruiting shoot is hardly seen above the heap of burnt litter; the inflorescence begins to emerge from the soil less than 36 hours after the first burning. The flower and fruit colors merge with that of the dark brown soil surface once the charred Volume 76, Number 2 1989 Notes 625 FiGURE 3. remains are blown away by the wind, and the vegetative leaves pass easily for the leaves of Bul- bostylis fimbristyloides and related sedges.

It is therefore Fruiting plants of U. nana. —a, b, c from Morphs A, B, and C, respectively. conceivable that, faced with myriads of ecological niches in this region, the number of representative species and infraspecific taxa is likely to be much higher than Hepper (1968) recognized. The distinct morphology of U. nana, with its peculiar habitat, sets it apart from previously known species of the genus. However, the existence of different morphs within a seemingly uniform ecological niche sug- gests that the population of U. nana may not entirely represent one genetic system. It is hoped that investigations now in progress on aspects of the biosystematics of this species will resolve this problem before long. The discovery of U. nana in Nigeria underscores the fact that the latest treatment of Liliaceae in West Tropical Africa (Hepper, 1968) is due for revision. It also indicates that Urginea may be represented in this subregion by many more taxa than are now known (Oyewole, 1975). LITERATURE CITED "us F. N. 1968. des P UM African mono- otyledons.

He was a passionate man, and some of his passions were shaped by early trips out of a St. Louis that was crowded and smoky into the gentle Missouri countryside, where he and his friends first sought unusual birds. Later he reveled in the autumnal drifts of asters, in enjoying the purple-brown trilliums and delicate orchids of early spring, and in collecting samples from the legions of sedges that he could see only dimly through the torrential cascades of sweat that poured from his brows as he crouched over gravelly riv- erbars during the torrid Missouri summers. Even the long-exserted anthers of the ribworts that ap- peared in early summer must have fascinated this unusual young man, who grew in knowledge about the diversity of plants that nurtures all who take the time to stop and appreciate it. Everywhere he went Julian was recognized for his achievements: the governments of Guatemala, Ecuador, and Venezuela; his alma maters at Wash- ington University and here at the Garden; the Missouri Department of Conservation; and the Sier- ra Club all soon came to know him as an inspiring and unique individual, and gave him abundantly of their prizes and awards. Everyone knows that Julian collected more plant specimens than anyone else has ever done, an incredible 132,000 speci- mens, and that he was a prolific writer and her- barium worker. In fact, if we hadn't known him personally, we might think —reading about his ac- complishments—that he was some sort of drudge, dreadful, demanding, and uninteresting. Nothing could have been farther from the truth, however; those of us who had the privilege of enjoying his company, whether in the field, listening to his fa- vorite music, or simply exchanging views on some current topic, know far better. Julian certainly did enjoy hard work, and ap- preciated all of those wonderful manifestations of recognition that were accorded him for his accom- plishments—to be included in the Guinness Book of World Records as the world's champion plant collector was for him an absolute delight. In his life, however, he was sustained to a far greater degree by the love of his many friends. Boyhood friends who ranged through the Missouri woods together searching for rare warblers retained the joys of their mutual admiration into the years of maturity. Those who had the privilege of climbing the steep, rocky slopes and breaking through the interlocking branches of the forests of Venezuela with him never forgot the experience, and ex- pressed their deep concern during his final illness. Once you knew Julian, you simply did not forget im. Returning here to his boyhood home at an age when most have slipped into the relaxation and hazy days of retirement and gentle decline, Julian undertook the preparation of an account of the plants of what is perhaps the least-known part of the world botanically, the interior of Venezuela, where the tepuis and gorges that he loved so deeply make up the spectacular fabric of the fabled Lost World. As he did everywhere he lived and worked, Julian renewed sturdy old friendships, and forged new ones, a process that continued all his life. Bruce and Luther, Gerrit and Jeany, Tamra and Bruno, and so many others—you each gave him much, especially during his final days of great physical discomfort, but you got far more than you gave. Julian's open, happy smile; his sweet, joyous, and dedicated personality; his attentiveness to the task at hand; and his unremitting, dignified friendship will form memories that will be with each of us until our own final days. For someone who spent his childhood amongst the beauties of bellflowers, gerardias, and desmo- ANN. Missouni Bor. GARD. 76: 627-651. 1989. 628 Annals of the Missouri Botanical Garden diums, gumweeds might have seemed a strange choice as the subject of a doctoral dissertation. These sunflower relatives exude a white, sticky sap that fills their unopened flower heads before they expand to reveal the golden-yellow inflorescence hidden within each. Gumweeds are relatively un- common in Missouri, but range widely over the American West and Mexico. Julian's graduate ad- visor, Jesse Moore Greenman, who trained an en- tire generation of American taxonomists here in St. Louis, was determined to complete the great task of John Torrey, George Engelmann, and Asa Gray —to make known the variety and complexity of the plants of our continent, and he assigned doctoral problems accordingly. For this purpose, )r. Greenman enlisted Julian, who was afire with his love of plants, into his army; and the young man set out along the dirt tracks and across the fields of the West, publishing his work ultimately in the Garden’s Annals. the 28-year-old Julian Steyermark, just married, there followed 21 years in Chicago, where he ultimately became Curator of Botany at the Field Museum. That institution, and his contact with the famous botanist Paul Standley, provided his introduction to the plants of Guatemala and brought home to him just how little we knew about the plants of the American tropics. Missouri's flow- ers remained his favorites, however, and he cul- tivated them lovingly, with his wife Cora, in their own wildflower garden near Chicago, a sanctuary now maintained by The Nature Conservancy. For 30 years Cora and Julian crisscrossed Missouri searching for plants, driving thousands of miles back and forth from their home, camping in riv- erbottoms, by dusty roadsides, or in forests, so that they would come to know more fully the detailed distributions and characteristics of the plants o this state. Their cultivation of many of these plants in their home garden was not merely a scholarly exercise; it was also an act of love, a celebration of their natural beauty and their individual char- acter, as anyone who has turned the pages of Julian’s exemplary 1963 Flora of Missouri will now. What memories those explorations provided Julian and Cora, and what times they shared to- gether! To know about some of them, read Cora's Behind the Scenes, a testimony to the beauties of our state and the joy that is in store for those who take the time to appreciate, understand, and enjoy them. Cora wrote: The morning was cold and clear. Pine trees and shrubs, gray and bent with ice and snow, lent variety to the icicled oaks. At the top of the hill we came upon the sunrise. The whole view for miles across the hills was a pinos blaze of crystalline purity. Against the sun, the tops of trees turned to polished gold, dadag i to silvered lower limbs rising above a b soft setting of snow-covered shrubs. Julian stopped the car. "I'm stuck with a view," És he m "Im afraid Pll break En if I move.’ t whole view looks as if it might break if you breathed on it. This is something you see once in a lifetime. I'm glad we stalled last night," I said and really meant it. From Chicago, Cora and Julian moved on to Caracas, where they traded goldseal, gentians, and Chimantaea, Sterig- The exchange puccoon for Brocchinia, mapetalum, and Heliamphora. proved a rewarding one, and Julian went on to add more to our knowledge of the plants of Venezuela than anyone had before. A quarter of a century was enough—filled with friends from Venezuela, new friends from the States, wonderful new plants, many of them extravagantly beautiful, and hundreds named in Julian’s honor, hundreds of them. After Cora’s death, Julian came back here to his home- town and began to write in earnest about the in- credible plants of the Lost World. His last work will be completed here, and will stand as a final testament to his industry and to his scholarship. As for any human being, however, what will prove to be even more important to all of us will be our memories, for Julian Steyermark was an inspira- tional person, one who projected his own values without trumpeting them, and thereby enriched all our lives, as he did the literature of botany. In concluding her book, Cora wrote: t was a long exploration = more than 30 years from which we have related merely a few experiences representing each “os of he la season. So we see —a book is not only written and rewritten, it is lived through a life of sweat, privations, and joys behind the scenes, before the final word is ever put on paper at was her affectionate term for Julian in us book] and I, hereby will the state to the next botar Is that not a reflection worthy of us here today? We all toil in a common field, inspired by early memories, contributing to knowledge, doing what we can for one another and regretting what we cannot do. In the plants that support and nurture us, enrich our souls with their beauty, and inspire our actions, we have found a common bond. Here today we have found another: the remarkable and full life of a truly luminous human being, our friend Julian Steyermark, whose fellowship we enjoyed so deeply, and whose life we will remember with grat- i eter H. Raven, Director, Missouri Bo- tanical Garden; from Julian Steyermark's me- morial service. Volume 76, Number 3 1989 Steyermark Recollections 629 During the 1940s in my beginnings as a botanist, I started to understand the importance of Dr. Jul Steyermark's works on the taxonomy of the Vane ezuelan flora. The National Herbarium already pos- sessed numerous collections made by the remark- able scientist. By the 1950s, our friendship had grown stronger and lasted for more than 30 years. His long and exhaustive research of the Venezuelan geography created a major collection that has con- tributed in a decisive way to enhance Venezuela's floristic inventory. His humility and generosity were the most out- standing features of his personality. A few years ago, before departing for Venezuela's Guayana, | asked Julian to inform me on the area I was going to visit, a place he knew and had explored. Among the helpful and valuable facts he supplied was the name of a man who knew the region well and could act as a “baqueano” [guide]. Arriving in the area, I found the person Julian had mentioned. I told him my mission in the area and that Dr. Steyermark had recommended him to me. To my suprise he “Mr. Steyermark? I have never heard > However, I insisted and slowly re- answered, such a name.’ peated, “Are you sure you don’t know Dr. Julian Steyermark?" His facial expression suddenly changed and he replied smiling, you mean Julian, of course I know him and I am ready to help you." This story helps to illustrate Julian's sense of humility, generosity, and harmony. His legacy as a scientist goes hand in hand with the personal attributes that made him a great human being and a beloved friend to those who knew him.— Leandro Aristeguieta, Universidad Central de Venezuela, Jardín Botánico de Caracas. When I arrived at the Instituto Botánico in Caracas in the summer of 1975 looking for a project to help me learn about tropical plants, I was brought into the office of one very busy, grum Dr. Julian Steyermark. Faced with a botanical neo- phyte, he suggested that I begin collecting plants from the hills surrounding the Instituto—a patc of secondary, deciduous forest in the heart of the city. Years later this project led to a paper we published together on the vegetation of the decid- uous forests of Caracas, but only after many jour- neys in each other's company to the few wooded areas near the city not yet overtaken by apartment buildings or “ranchos.” Following up our finding of five species of the coca genus, Erythroxylum, growing side by side in the hills above the Botanical Garden, a student of mine at Simón Bolivar Uni- versity in Caracas completed a wonderful thesis on FIGURE 1. in southern Ecuador Fuchsia steyermarkii, from cloud forest the comparative reproductive biology of the group. Another result of our study was the recognition of two species new to science, Eugenia mcvaughii and Erythroxylum undulatum, both based on plants found less than 100 meters from the front door of the Instituto. It was the shortest trip I know of for specimens to be placed in the type collection of the National Herbarium. Now years later I sit in Julian's former office— sometimes in his chair, picking up where he had left his unfinished project, the Flora of the Ven- ezuelan Guayana, more "iren known as the “Flora of the Lost World.” Julian was a *'ba- queano” (guide, in sas to me, for he opened up many paths that I was to follow. My botanical tribute to Julian was the naming Just after his death, I was to return to the original site where the plant was found, in lush cloud forest on the steep slopes south of the Nudo de Sabanilla, of Fuchsia steyermarkii. in southernmost 630 Annals of the Missouri Botanical Garden Ecuador. | got there in a rented taxi, a few hours by car from the city of Loja; he got there by foot and mule, on a fortnight trek through endless rains, in October of 1943. His Fuchsia is a most unusual species, with needlelike leaves, and if it survives in cultivation it will be highly esteemed. Many simple folk all over Venezuela knew and remembered Julian. I met some of them, usually in remote places, like “Horacio,” a Makiritare Indian who spoke no Spanish but had climbed many a tree for him; and José Mendoza, an Andean homesteader from San Vicente de la Revancha, whose senile father had guided Julian years ago far into the páramos towering over the valley. Both reacted similarly when I mentioned Julian's name: a big, amused grin accompanied by signs of respect for a man so dedicated to his botanical mission. — Paul E. Berry, Missouri Botanical Garden. I had been at the New York Botanical Garden as a doctoral student for all of three weeks in 1980 when I first met Julian Steyermark. He was visiting the New York Botanical Garden to consult our Guayana Highland collections and to collaborate with Bassett Maguire on several taxonomic treat- ments. Of course, I already knew of him by rep- utation. | was a novice to tropical botany, so in an attempt to say something intelligent to him I dug back into my M.S. thesis on /soetes and located the citation of Steyermark 85179, which I had identified as /. melanopoda Gay & Dur. | reported this to Julian, and to my amazement he immediately told me where in Missouri the specimen had come from and the month during which he collected it 23 years previously! This was not to be the last time over the following eight years years that Ju- lian's prodigious memory would impress me. | also became aware of Julian's capacity for work as I observed him during his subsequent per- iodic visits to New York. Occasionally, he would share my office because of our mutual interests in the Guayana Highland flora. He stayed in the Gar- den's Snuff Mill apartment during his visits. By 7:30 A.M. he would be at the herbarium. With a single-mindedness he worked on specimens until about 6:00 P.M. with only a half-hour break at the lunch table. Julian was not one for idle chat, and he clearly did not like to be disturbed while working. At six, and also with a single-mindedness, he would round up any remaining staff and students and go have a huge dinner, followed always by a stop at the local ice cream establishment. Occasionally, he would take in a movie, but more often than not he would head back to the herbarium for several more hours of work before retiring for the night. And thus, day after day, he would make his way through huge piles of specimens, writing descrip- tions of new taxa on the spot in his nearly illegible scrawl. Julian confessed that he “over-described”” occasionally, and that perhaps he split excessively. lowever, he justified it by saying that he viewed his role as one of describing biotic diversity as he saw it. He would leave it to following generations of botanists to determine just how “good” his de- cisions were. How history will judge his taxonomic decisions does remain to be seen, but there can be no doubt that Julian had an excellent "eye" for I also know that I trust his specimen annotations more than those by just about seeing differences. anybody else. During the first half of this century, when a researcher needed quick, reliable deter- minations for neotropical specimens, the solution was "send them to Standley." Julian was heir to this role. His magnum opus, Flora of the Vene- zuelan Guayana, will aptly attest to his unparal- leled knowledge of the neotropical flora. In an age of few heroes, Julian was one for many of us.— Brian M. Boom, The New York Botanical Gar- Len. Hace cuatro anos, el 7 de junio de 1984, tuve el honor de darle con alegria y en nombre de los botánicos de Venezuela, un adiós, un hasta luego, a Julian Steyermark. Esta despedida era transito- ria, ya que por su propia decisión, volvia a su tierra natal, Saint Louis, Missouri. A pesar de su ida, Julian no podia resistir la tentación de permanecer mucho tiempo allà, solo en el norte, razón por la cual, con frecuencia hasta principios de este ano, regresaba a Venezuela, pues como el decia: amor a primera vista," fue su reacción al ver por vez primera a este pais en 1943. Y, cual enamorado, exclamó: “Mi amor a Venezuela, se debe no solo a sus flores, a su fauna, a sus paisajes, sino tambien a mis amigos quienes poseen una alta sensibilidad, capacidad, y deseo de trabajar en la botánica y en la conservación de sus recursos naturales. Por eso mi amor por Venezuela fue instantáneo.” Julian Steyermark, nació en Saint Louis, Mis- souri, el 27 de enero de 1909. prana edad sintió el reto de conocer la naturaleza que lo rodeaba. Allá por el año de 1925, cuando era Boy Scout en su ciudad natal, se interesó en la zoologia, fijando primeramente su atención en esde muy tem- las aves. En ese mismo ano ingresa al club de Biologia de su colegio y su espiritu naturalista se concentró en el fascinante mundo de las plantas. Desde entonces, sólo vivió en función de ellas. Combinando sus estudios con sus labores de Guia Naturalista en los parques de Saint Louis y sus Volume 76, Number 3 1989 Steyermark Recollections FIGURE 2. alrededores, fue formando una buena colección de plantas la cual fue adquirida por el Herbario de Missouri en 1934 por 84 dólares. Este dinero fue la base para comprar su primer vehiculo, para poder continuar con mayor facilidad sus trabajos botánicos. Julian llegó a Venezuela en diciembre de 1943, cuando en misión del gobierno de su patria de vino a buscar la corteza del árbol de la Mundial para combatir el paludismo. Sus primeras incursiones botáncas en el pais las efectuó en lo que es hoy el Parque Nacional El Avila, de alli pasó al Oriente de nuestro territorio, regresando a Estados Unidos en 1945 con una colección de 8,000 muestras botánicas. La belleza escénica de los diferentes ambientes venezolanos, el contacto con las plantas, coló tan hondo en la sencilla humanidad de Julian, que sonaba que Venezuela debería ser su pais. Este sueño, cual regalo de navidad, se convirtió en realidad cuando en diciembre de 1959 recibió la invitación de Tobias Lasser, por recomendación de William H. Phelps, para que formara parte del personal del Herbario Nacional de Venezuela, donde permaneció activamente como estudioso de la flora Venezolana. Por su larga trayectoria y aportes al conocimiento floristico del pais recibió entre otras las siguientes distinciones: Orden Andrés Bello (1974); Orden al Mérito en el Trabajo, Primera Clase (1974); Orden Henri Pittier (1979); Premio William H.

Julian Steyermark, después de sesenta y nueve años de búsqueda y trabajo activo en su mayor obra botánica, Flora of the Venezuelan Guayana, murió en Saint Louis, Missouri U.S.A, el 15 de octubre de 1988. Por eso hoy siento la necesidad de darle en nombre del personal del Jardín Botánico de Caracas un adiós lastimoso, con dolor y nos- talgia. En este momento recuerdo, que un día en fe- brero de 1984 Julian me dijo, sentado en la cima del Aratitiyope (Templo Sagrado de Las Guaca- mayas), Territorio Federal Amazonas, en un mo- mento de descanso y contemplando la majestuosi- dad reflexiva del paisaje, “Francisco mi mayor deseo es emplear todas mis fuerzas y mi dinero, para seguir explorando este maravilloso pais.

He was painting an orchid in the old Floral Display House of the Missouri Botanical Garden during the annual orchid show. At that time he was an un- dergraduate student at Washington University. Later Julian became chairman of the botany group of the Webster Groves Nature Study Society. He wrote articles for Nature Notes, which is the monthly publication of the society. He also spoke at the meetings and led botany group field trips to local areas. Since Julian didn't have the use of an automobile while he was a student at Washington University, he depended on his friends to take him to areas that he couldn't reach by streetcars or trains. He and I went on a field trip to northwestern Missouri to the loess mounds of Atchison and Holt counties during the Labor Day weekend in 1932. This area “=== Louis, Missouri, June 1929.

On several occasions Julian and I took street- cars to South Broadway and found many intro- duced plants along the railroad tracks near the Mississippi River. Some of these plants were very seldom found elsewhere in our area. On the way home from these streetcar trips, oeil identified plants in vacant lots along the city stre On one of our field trips to the Oaks Julian saw a sedge that he wanted to reach on the other side of a stream. We walked through the shoulder- deep water to reach the sedge. He climbed the steepest slopes and descended into the deepest val- leys in his search for plants. Julian never seemed to tire, and if he was tired, he continued on anyway. ne of Julian's favorite places was Pickle Springs, where many rare plants were found. This area is now Pickle Springs Natural Area. Another favorite Mis- rare area was near the Meramec River at Pacific, This area, plants, is now known as Pacific Palisades. souri. which also contains many Although Julian was so dedicated to collecting Volume 76, Number 3 89 Steyermark Recollections 633 and identifying plants, he did take some time off to play tennis at Tower Grove Park. Also he at- tended some of the Webster Groves Nature Study Society's parties. On the day that Julian received his Ph.D. degree from the Henry Shaw School of Botany of Wash- ington University in 1933, I happened to meet him with his parents at the Missouri Botanical Garden. He couldn't stay away from the garden that meant so much to him, even on his graduation day.— Arthur Christ, St. Louis, Missouri; from Julian Steyermark's memorial service. I am very sad with the passing of Julian, a taxonomist extraordinaire and a dear personal friend. I feel very privileged to have known him closely during the last two decades of his life. Julian was truly one of the greats in his field and his contributions to taxonomy, exploration, collecting, and conservation will long be remembered and rec- ognized— and use Of all the people I have known personally, he, perhaps as well as anyone, exemplified a person of whom it can be said without any exaggeration that his vocation was also his avocation. I will, above all else, remember him as a person totally devoted to his work and one for whom his work held a never-ending fascination. I would like to recall several personal experi- ences and incidents that illustrate some aspects of his personality and career. first got to know Julian personally in 1971, when as a graduate student | went to Venezuela to study and collect plants for my thesis. I was already well aware of his many accomplishments and his international reputation. As with almost any other novice going to a foreign country to collect, I was having difficulties in making the nec- essary arrangements. With some trepidation, I asked for his help, and I was very grateful that he took time to arrange contacts that made my work much easier. I later learned that he guarded his time very jealously, surely a necessity for someone who re- ceived little secretarial help at the time, who pub- lished thousands of pages, and who was unrivaled as a plant collector. However, if you were serious about plant collecting, he would often try to help. He was very well aware that the next 20 or 30 years might be the last chance for any of us to study and collect the undisturbed vegetation in many areas of Venezuela that had never been bo- tanically surveyed, and he always felt only a small portion of the country had been adequately sur- veye After I joined the Missouri Botanical Garden in 1972, a number of other staff members, including Tom Croat and Al Gentry, collected in Venezuela, and we seemed to pass muster as plant collectors since Julian proposed in 1975 that the Garden and the Instituto Botanico organize a cooperative pro- gram of joint expeditions to areas in which the vegetation was being severely damage fter we secured funds for this work, Julian and I made a number of field trips together, and it was then that I really got to know him well. Julian was a very goal-oriented person who doggedly pursued his objectives until they were accomplished, whether it concerned writing the Flora of Missouri during his free time or whether it concerned collecting plants from a tepui never before explored. en he went to the Field Museum in 1937, he had already collected over 25,000 plants. There he worked under and was greatly influenced by another of the great plant collectors, Paul Standley, who was to collect well over 100,000 numbers by the end of his own career. Julian early on, as he told me early during our association, determined in his own mind that he would eventually surpass Standley’s numbers, and he ven on a daily basis, a had Standley before him— would set a goal of a certain number of collections to be made that day, and he would challenge his companions to do the same. He would invariably have a very precise recall of what he collected each day, and he loved to challenge you to guess the totals gained by each person, spicing the proceedings by betting a milkshake on who could guess the closest. I soon learned to keep closer track of what I was collecting! Although Julian was a modest person who lived a quiet, simple life, he, like all of us, appreciated recognition. After several years of working togeth- er, I knew that he was proud of the large number of plants he had collected, and I began to think of ways in which this collecting record might become more widely recognized. I finally hit upon the idea of nominating him as a champion plant collector to the Guinness Book of World Records. Because I was a bit uneasy that he might consider this a trivialization of his accom- plishments, I checked out the idea with him be- forehand, and he approved. Unfortunately, it took the editors of Guinness several years to decide what plant collecting was all about and whether it really had a place in their book. In the meantime, Julian would ask me every time I came to Vene- zuela what had happened to this proposal, and | had to tell him to be patient, that it was still in the Annals of the Missouri Botanical Garden works. The record was finally included in the 1986 edition, and Julian seemed to enjoy the additional attention it brought him from the popular media. I earlier mentioned that Pll always remember Julian as a person totally devoted to his work. This perception comes from watching him put in long hours of fiercely concentrated work each day, sev- en days per week, and 52 weeks per year, but it was also brought home to me in a much more amusing way on our first trip together in 1978. Our objective on that trip was to collect in a small range of mountains known as the Cerros de Bachiller in the Coastal Cordillera of northern Ven- ezuela, where new agricultural developments seemed certain to destroy much of the virgin vegetation in the near future. Close to a small mountain stream at the foot of the mountains, we had constructed a nice base camp, from which we collected every day. As was customary, we slept in hammocks strung beneath a plastic sheet to keep out the rain. Julian would always wake just before dawn, and as we were getting ready for the day's collecting, he would tell me his dreams of the night before. Every morning during the two weeks of that trip, the dream he recalled would be enjoyable and botan- Their s e "Lost World," and he would discover the most ailing ical. setting would often be in t new plants, which often combined bizarre char- acters from several families, so that he would be very puzzled and strongly challenged on how to interpret these strange plants. After a couple of days of this, I began to think to myself, here is an even more devoted man than I had realized, not only does he devote most of his working hours to botany, but even his sleeping hours are devoted to it. So these are some of the ways Pll always re- member Julian, a valued friend, a man of great accomplishments, a man truly devoted to the good things of this world, and one who leaves an enor- mous legacy to us all.— Gerrit Davidse, Missouri Botanical Garden; from Julian Steyermark's me- morial service. Omnia fluerit. Everything flows. Fifty-five years ago Julian Steyermark, then 24, and taking his Ph.D. here, wrote to me in the spring of 1933— I was at UCLA of Grindelia collections that I had made, gum- at the time—asking for the loan weeds of the Compositae (as we called them then). On June 21st he wrote again, that the loan was being returned and added that he was tending a 34-acre plot of grindelias, and rushing his getting a Ph.D. He wrote, “I shall be starting off soon on a 2 or 3 weeks botanical expedition into unexplored parts botanically of Missouri, getting into many remote sections." Some readers may wonder when Julian really began botanizing: on October 13th, 1930, he collected Grindelia lanceolata along the railroad tracks bordering the Washington Univer- sity campus. That collection was numbered 1506. By September 11, 1932 he had numbered to 7/64, or 5,658 field numbers in less than two years. Now and then I encountered Julian at the Gray Herbarium or the New York Botanical Garden. Then, with deep pleasure, I came here in 1986 to work in the library, as Julian before me had come to forage in the hortus siccus, the dry garden. In researching the vismias and the shrubby gentians, I came to know Julian's detailed collections and his keen interest in plant geography and those “unexplored parts botanically” their specimens you shall know them!— so true of letter of 1933: **One derives the chief or almost the chief pleasure of Venezuela. By botanists. Let me return to Julian's from studying plants in their natural habitat, ex- ploring for them in remote places which add to the zest and thrill of discovery. At least I have always felt that way and most field naturalists hold similar opinions." The tepuis used to be called the "Lost World" but that was before Julian. Omnia fleu- rit.— Joseph Ewan, Missouri Botanical Garden; from Julian Steyermark's memorial service. My introduction to Julian Steyermark was through the Flora of Guatemala while working as a Peace Corps volunteer in Honduras on a floristic survey of one of the central valleys. Honduras does not have any written flora, so the next best thing was the Flora of Guatemala of which many vol- umes were written by Standley and Steyermark. Filled with useful information, excellent keys, and descriptions, it taught me a great deal about trop- ical botany. When I was finally preparing to leave Honduras with some of my more interesting col- lections, | was directed here to the Missouri Bo- tanical Garden as the best place to have them identifie When 1 finally made it here some months later and luckily was able to get a job, I was told that Julian Steyermark had just come up from Vene- zuela and was on the staff! One of the first things that I wanted to do was meet him, and you can imagine my surprise and pleasure upon learning that I was going to be working for him, and how much even more surprised I was when three months later | was in Venezuela on a major expedition to the Lost World! It was a real thrill and a tremendous learning experience to work in the field with Julian. He had Volume 76, Number 3 989 Steyermark Recollections 635 RE 4. Field trip, 1929-1930.

When I first went out on my own to collect some specimens I found a beautiful plant that I thought was very unusual; it had large bright red bracts surrounding a dense cluster of flowers. When I returned to camp, I pulled it out of my collecting bag with pride to show him. But when he saw it, he took it from me in disgust and threw it to the ground, saying sternly “this is Psychotria poep- pigiana subsp. barcellana, one of the most com- mon and weedy plants of South America, don't ever collect it again." I was a little bit embarrassed, so the next day I made even more of an effort and risked my neck to get up on some diffici bluffs. When I got back to camp, I sheepishly pulled another member of the same family out of the bag lt sandstone to show him. This time, however, he looked at it with a great deal more interest, a puzzled look came over his face, and he admitted that he didn't know what it was, and that it likely something new. From then on I learned that when- ever he gave that look at a plant, it meant some- thing interesting had turned up. In this particular case it was a genus of the coffee family new for was very science. Fieldwork was very special for Julian—rather than “vacations,” he went on field trips. It was impossible not to be caught up by his enthusiasm for collecting plants. He always likened collecting to a “treasure hunt." Even with his two artificial hips, he would plow through brush, crawl over and under logs, fall down, laugh about it, and push on. He truly liked collecting all kinds of plants, but I think that the Bromeliaceae were his favorite fam- Julian was involved in the first helicopter ex- pedition in Venezuela, which took place in 1967 to the isolated Cerro Jaua. He quickly realized the advantages of that mode of transportation and found that it would increase even his amazing productiv- ity. He would use it frequently in the following years to get to some of the most inaccessible of the Lost World summits. To think that in all the years prior, when he made so many of his famous expeditions to some of the most remote areas in the country, that everything was by foot, including long and hazardous climbs to the tops of several of the more prominent tepuis, such as Chimantá and Auyan-tepui. Once I understood the complex- ities involved in these huge expeditions back then, my admiration for him increased even more. e was a great friend to the Indians of the region. They enjoyed his sense of humor and spirit of adventure. He is somewhat famous in certain Indian tribes. Two years ago, when we were plan- ning a trip to a series of unexplored mountains in the heart of the Lost World, we were surprised to be met by the son and grandsons of an Indian who had worked with Julian back in the 1940s. They 636 Annals of the Missouri Botanical Garden had heard that **Hulian Esteyermark" was to be back in the area, and were eager to volunteer their help. On a personal side, it took a while to get to know him, and he did have some unusual ways. I thought that he was kidding when he told me about his liking for rock & roll music until he showed me his more than 800 records ranging from Elvis Presley to the Rolling Stones. He also loved Venezuelan and Andean folk music. — He loved to bet milkshakes on whether his friends could identify a plant or not. I paid out my fair share to him and to Ron Liesner (an expert at plant family identifications). -He would eat sparingly for breakfast or lunch, but there were few who could match him at the dinner table. Buffets at nice restaurants were his favorite, and he would go back time after time before he was ready for dessert. —Other than fancy buffets, he thrived on fruits, vegetables, and ice cream and was a great exper- imenter with native edibles. Flower fragrances were we would have contests in the field to see who could find the most fragrant flower, irresistible to him; and he smelled every one with great pleasure. — Swimming was a favorite pastime of his. The only time that he would take off from the herbarium or field (or let any of his assistants do so) was to go to the beach. He loved floating in the waves and would do so for hours at a time. Julian was a most ardent and effective conser- vationist. He worked hard in Venezuela through the National Park Service to protect the forests in the North that were, and still are, rapidly being destroyed, and was instrumental in identifying many protection. In late 88, we were told that the President of Venezuela areas in the South worthy o was signing into legislation a new National Park in the delta of the Orinoco River. It was planned with Julian's help. Finally, I would like to share some parts of a letter that was sent to Julian a few weeks ago that illustrates his impact upon others around him, not just as a botanist, but as a person who could inspire others: was a student of your Biology Class at University City High School during the 1937-38 period at the time E K to your leaving for the Field Museum in Ch . My memories of deed are very strong and ae e as a teacher and as a ou provide a great ia model for a i anali interested in sci- ence. And | remember how impressed I was with the fact that my teacher was leaving to become Curator of a portion of the famous Field Museum. You and several of the other faculty members at U. City H provided great inspiration to accomplish at that point in my life. Thanks. Fifty years later, another student of his feels the same way. I am deeply saddened to lose a great friend and a teacher. I will never forget him and what he has done for botany, for conservation, and for me.— Bruce K. Holst, Missouri Botanical Garden; from Julian Steyermark's memorial service. The expression on his face was rather eloquent when Julian saw the pile of newspapers that I had put in front of him on his desk. He knew that | was an ecologist starting to do research in the cloud forests of Rancho Grande, in National Park Henri Pittier some 100 km west of Caracas. My "bo- tanical collections" consisted mainly of large, labeled leaves pressed between five or even ten sheets of newspaper in order to assure their drying. “What am I supposed to do with this?" Julian asked me impatiently. “Well, I think that you can identify them," I answered a little bit scare fter a few silent minutes, during which Julian lane ed through the "specimens," he re- turned the pile to me and said, shaking his head, “These specimens are unidentifiable, they are all sterile; there is nothing I can do with them.” And with these words he continued typing labels on his old OLIVETTI typewriter, and I suspected that | had done something wron After this episode, vids h occurred sometime in early 1974 in Julian's office at the Instituto Bo- tánico in Caracas, | realized that plant collecting in a tropical cloud forest was rather different from what I had done before on a very limited scale in the Mediterranean macchia of southern ltaly or the island of Sardinia. Under Dr. Steyermark's guidance I learned how to make proper plant col- lections and how to identify them to family, genus, or even species. I soon realized, too, how fortunate I was to have such an outstanding teacher: every passing day | was increasingly impressed by the astonishing taxonomic knowledge of this man, who seemed to be omniscient and blessed with a re- markable memory of the most complicated plant mes! After having been invited to my first chili con carne at Julian's home (his favorite dish expertly prepared by his wife Cora), strengthened, partly because in the meantime I had improved the quality of my botanical speci- mens. À couple of vears later, we engaged in a our relationship joint venture, resulting in the publication of the Volume 76, Number 3 1989 Steyermark Recollections Flora del Avila. Julian wrote most of the keys of that book at home while recovering from his two hip operations and while I was in Austria concluding my Ph.D. thesis. At my return to Venezuela in September 1976, we then had a rather hard time finishing the rest of the manuscript (some 1,600 pages), since my Tyrolean stubbornness was not less persistent than Julian's Missouri stubbornness! This ook, however, constituted a tremendous experi- ence for me, and since then we had become col- leagues, working together very closely in the In- stituto Botánico. From then on, Julian was always anxious to be the first to see my collections from the Venezuelan Amazonas and later from the many tepuis of the Guayana Highlands. In 1982 we decided to start another new project titled Flora and Vegetation of the Venezuelan Guayana. We realized that such an enterprise would take years of most intensive work, but we both decided to dedicate all our efforts and re- sources to that project. Although destiny later di- vided our paths, Julian and his collaborators have advanced relentlessly towards completion of that flora, whereas I have continued to contribute by collecting interesting plants from the many places visited during my ecological and phytogeographical fieldwork in that region. It was a great satisfaction for me to invite Julian to an expedition into the Chimanta massif, one of the richest Guayana mountains, where he and John Wurdack had done such pioneering botanical ex- ploration in 1953 and 1958. When we established camp near a huge colony of Chimantaea mirabilis, a most striking member of the Compositae discov- ered by him in 1953, Julian could not hide the emotion caused by this reencounter after 25 years! And then, there he was, the " Julian Stey- ermark, sitting at his camping table labs and pressing plants and plants and plants, amazingly numerous plants every night (at that time he was at his number 128,000). And every two minutes he would call me and exhibit another exciting find, or explain another variation or another novelty. One year later we would be again on the same mountain and discover a new genus (4co- panea in the Theaceae), and then get flooded at our camp at 2 o'clock in the morning with icy water half a meter deep from the nearby cano! Julian Alfred Steyermark, the great botanical explorer of the Guayana and many other places of the Venezuelan country, has now left us, but his memories, as numerous as his botanical collections, will always accompany us from tepui to tepui, to- gether with the gratitude of having had the privilege to be one of his students!— Otto Huber, Caracas, Venezuela. I first heard of Julian Steyermark when I was a student at the University of Wisconsin. Dr. Hug Iltis said he wanted to prepare a flora of Wisconsin that was as good as Steyermark's Flora of Mis- souri. Julian enjoyed hearing that. I first met Julian when I went to Venezuela in 1977 as part of the joint Missouri Botanical Garden and Herbario Nacional de Venezuela project spon- sored by NSF and CONOCIT. When I arrived, Julian was skeptical and concerned and told me about the difficult conditions: rain, heat, snakes, and other perils. Julian, Francisco Delascio, and I went to the Delta Amacuro (delta of the Orinoco River) for a month. The collecting and the trip were exciting and one was able to ignore the difficult conditions. I quickly learned Julian was very good at spotting plants to collect. He first started using clippers when he saw me using them and we sometimes joked that he learned to collect plants from me (he had 114,000 collections when we met) Numerous field trips with Julian were a privilege. I learned many plants from him and how to find specimens to collect. We frequently bet a milk- shake if we thought we could catch the other person not knowing a plant to family. Even a sterile plant was game if that person collected it. Usually I could catch him only if it was a genus that was unusual for the family and the genus was new for Venezuela. We also bet milkshakes for guessing how many plants we had collected before we pressed and numbered them. I, also he, sometimes would collect numerous extra mosses so the competitor's guess would be too low. Once, after Julian had guessed right three days in a row, he stated his guess aiming at a fourth win, then I guessed one lower, and Ángel González guessed one higher. Julian had to do something else. Ángel and I pressed the plants and wrote the field notes. It came out to Julian's number! Ángel and I decided to trick him. One species of herb had both flowering and fruiting individuals. We split them into different collection numbers. But Julian had the last laugh. Not only were they different species, they were different genera! We also guessed at arrival times for a milkshake. Cora, Julian's wife, said they had bet ice-cream cones when they did fieldwork in Mis- insects, ouri. Julian loved to try different restaurants and go to the movies, and many of his friends enjoyed going with him. For a long time, Julian was my closest friend. Julian had a good sense of humor and it was fun to tease him. But it did annoy him when I said I was from Missouri and to show me. Gerrit Davidse did the same. For a long time he idn't consider us Missourians. un 638 Annals of the Missouri Botanical Garden e often corrected my Spanish. I sometimes joked that Julian taught me Spanish. He vehe- mently denied it, but everyone else liked it. When he came to Missouri, he had to get his driver's license, and I had to teach him to drive my car. Later, I joked I had taught him how to drive. He would mention the first two things the driving examiner asked were the lights and horn, and I hadn't shown him those. Julian claimed that he had shaved every morning since the thirties. We could be short of water and he would still shave. He, Bruce Holst, and I were almost stranded on top of a tepui without our things. Bruce and I kidded him that we would see him unshaved. But then we decided he would shave with his machete. The helicopter came so we didn't find out. Julian and I were in some very risky, potentially dangerous places in collecting. But the most wor- ried and most concerned I ever saw him was when we arrived back in Caracas and he couldn't find his hairpiece. It frustrated him when women saw him without his hairpiece the first time in the field and told him they thought he looked better without When we were stranded on Cerro Duida, wet, with no shelter or supplies, in a potentially fatal situation, Julian joked about dying on a tepui. We assured him that was fine as long as it was some other tepui. In the field Julian often remembered collecting the same rare species 30 years previously. An amazing number of species were either described him or named after him. I wonder what level Venezuelan botany would be at if it were not for Julian. He worked fast, long hours, and accurately. One could go many places in Venezuela and local people would remember Julian when he was there 20 to 40 years previously. Identifying specimens, I worked on many dif- ferent plant groups. Julian was a good friend be- cause I could talk about many different groups and he had worked on them also. For quite a while when I ran into a problem with a plant group or if I had a plant I couldn't identify to family, my first reaction was still to go ask Julian, only to remember Julian was no longer here.— Ronald Liesner, Missouri Botanical Gar- den. I first met Julian Steyermark in October, 1963, at a difficult time in my life, and I am proud to say that since that time, he has helped me more than anyone else. At that time I was an unemployed and com- pletely frustrated young man 24 years old; and just “to kill time," I decided to draw flowers. So I began to go around with some paper and a box of color pencils, and devoted myself to drawing flowers in Caracas near where I lived in a student dormitory. After a month or so, I had checked all the gardens, houses, and whatever natural vege- tation there was around and had exhausted inter- esting subjects for drawing and so expanded into surrounding neighborhoods, eventually reaching the Botanical Garden of Caracas, where there was a large variety of exotic and beautiful flowers. remember that one day, while concentrating on trying to reproduce the colors of a paradise" flower (Strelitzia reginae), a man came up to look at my work. I had seen him occasionally on previous days, but we never had spoken to each other. He was August Braun, the head gardener. After exchanging some comments, he told me that there was no artist at the Botanical Garden, since the former artist (the late Mr. Ebersteins) had retired four months earlier; and he suggested that I show my drawings to Dr. Lasser, the director. The following day I took some of my best draw- ings and showed them to Dr. Lasser. He liked them but said that drawings needed for scientific publi- cations had to be more “objective” and made with black india ink. As I had no experience with that kind of drawing, he introduced me to Dr. Julian Steyermark and asked him to give me some ori- entation. So | met the man, and got the job! After I had gained some confidence, in 1963 Julian asked me to draw a new species that he was describing, Palicourea chimo, and 1 complained that I had only herbarium specimens, not live plants. Julian, who also began his botanical career as an artist, understood and helped me look for a solution and invited me along on a trip to Naiguata, on the northern side of the coastal mountain range of Venezuela, where he had not been before. The Palicourea was encountered and drawn fresh. On the two-day expedition we found a new species, which Julian named Heisteria olivae (later placed into the synonymy of H. latifolia) to honor our guide, the young architect Francisco Oliva Esteva [see recollections in this volume J. Julian was so impressed by the rich vegetation there that two weeks later we went back to explore further. As Julian had begun his botanical activity in Venezuela in search of quinine plants and was an adviser to a large drug company in the U.S., he was always interested in potentially useful plants as suppliers of drugs. On our second expedition to Volume 76, Number 3 1989 Steyermark Recollections 639 the coastal range, we found a big Lacmellea tree, called **vaco negro" (black cow) by our guide, who stated that its sweet, milky sap was used as a remedy for asthma. Since we found only flowers and fruits on the ground, Julian felt frustrated, but I returned a few weeks later, climbed the tree using and collected several complete specimens. I illustrated these, and Julian named Lacmellea costanensis as a new species. So delighted was Julian with the scenery of those slopes facing the sea, completely carpeted by virgin a liana cloud forests, that he soon made yet another ex- pedition there. On this third trip, we went with Mr. G. . Dunsterville, the great orchid artist, and his wife. Nora. Cora Steyermark also came with us, but, as she was suffering from some bad health and could not match our pace, Julian went ahead with a bunch of yellow and red woolen threads, dropping them from time to time along the trail for her to follow. So, late in the afternoon, Cora reached us bright with joy and carrying all the threads she picked up along the trail. n this same trip, Victoriano Carreno Espinoza joined us. Julian had met him a month earlier on a previous expedition to Cerro Humo in the eastern peninsula of Paria. He was so satisfied with Victor’s knowledge of plants, skill, and enthusiasm, that Julian brought him to Caracas and helped him get a job in horticulture at the Central University. Victor continued to work with Julian and quickly became his faithful and efficient assistant on many expeditions throughout Venezuela during a fifteen- year period. When I met Julian, he was living in an apartment complex called **Residencias Magnolia" located in Los Palos Grandes, Caracas. The apartment had a terrace where he kept plants that he brought back from his botanical expeditions. He would lead visitors on a ritual tour around the garden to give an explanation of the plant names and the regions they came from, with considerations about their color, shape, or scent. But, Julian's expeditions were so frequent and fruitful that the apartment's terrace became too crowded, and about 1971 he moved to the suburb of Santa Eduvigis. There he had more room to display his plants and on the back side of the house he created a miniature jungle under a mango tree. In some cases Julian collected sterile plants, which he brought home until they flowered and then made herbarium specimens from m. Besides the small garden space, noise from traf- fic, and the fact that their house was broken into bothered Julian and Cora, so in mid-1975 they found a new house in the neighborhood of Santa Fe Sur. They were particularly pleased with it, because from it they enjoyed a complete view of Avila National Park across the Caracas Valley, and it was close to a place officially listed as a “green area," where supposedly no other buildings could be built. But several months later, in spite of all the official statements, construction began on a huge apartment complex whose wall reached right up to the Steyermark's garden. He felt very frustrated, and in his field book he remarked sadly, “Nov. 20, 1975. Destruction of green area back of our home." Yet the new house still had room for gardening, and the Steyermarks displayed the beautiful col- lection of bromeliads on the porch and put the aroids, orchids, begonias, peperomias, and ferns under a plastic net. In the center, there was a planter of red roses, surrounded by several Hip- peastrum lilies, and another plant of rosemary surrounded by the thorny Euphorbia splendens. In back, towards the new apartment complex's wall, there was a Chrysalidocarpus lutescens palm, a Tibouchina semidecandra with big purple flow- ers, a Mussaenda erythrophylla, a healthy Clusia minor with waxy rose flowers, a terrestrial Cyr- topodium orchid, and other miscellaneous herbs. On the right side, climbing on the fence was Aris- tolochia ringens, Heliconia caribaea, Nicolaia elatior, and Lafoensia with white flowers pollinated by bats. In a pot, there was also a “lily of the valley" with very fragrant white flowers n Julian especially enjoyed. On the side of the garden close to the porch grew a row of [ris confusa that never bloomed. Once a month, Victor went to the house to cut the grass and clean the garden. Cora, a member of the Audubon Society, en- joyed observing birds, and every day would put bananas and oranges in a feeder to attract them to the garden, and sugar water for the humming- birds. She kept a diary of the garden and recorded the exact date of blooming for every plant, days of rain and sun, and other data for the garden's management. She was also one of the founders of a garden club, which in 1973 created a scented garden for the blind along the avenue Rómulo Gallegos in Caracas. On many occasions Julian would honor me with an invitation to dine in his house, where I thor- oughly enjoyed Cora's excellent cooking, especially the pies and brownies. Sometimes when we came back late at night from some expedition, he invited me to sleep in their house in the guest room. The following day, of course, I would get a delicious 640 Annals of the Missouri Botanical Garden breakfast. | remember that when we sat at the At that time Julian was preparing a monograph breakfast table, Julian and Cora would recount the dreams they had the night before. On a trip to Puerto Cabello in 1973 with Julian and Victor, I found out that Julian had a love for snakes. We walked along an old canal breached in areas and useless due to many rocks and earth that had fallen into it; little waterfall, it was full of clear and fresh water. Julian, who loved to drink from sparkling streams, put his right hand on the edge of th bent over to take a drink (with the left he was holding the plant press). When he finished drinking, and before he stood up, he spotted a poisonous snake out of the corner of his eye, a fer-de-lance but in a corner, under a e water and (Bothrops atrox), just between his hand and his cheek. Victor hurried there with the machete to kill it, but Julian didn't let him; instead, he pushed and chased the snake away into the high vegetation. In 1983, Julian returned to that area again with Paul Berry and me to gather specimens of Sela- ginella gigantea, but the old trail was completely lost. Paul and I managed to reach the Selaginella site, but just as we arrived, a heavy thunderstorm came up. Paul hurried to make a collection of the rare Selaginella, and then we headed straight down the mountain, since we lost our trail very quickly. ‘hen at last we reached Julian half an hour later, the rain still falling, we found him sitting on his press, trying to protect himself with a completely wet piece of paper but he regained his spirits as soon as he saw Paul's collection. All that area where the Selaginella is found now belongs to the San Estaban National Park, created in 1986 thanks to Julian's enthusiastic report In October 1970, Julian joined the Venezuelan Brazilian Frontier Commission in a survey of the Cerro de la Neblina, the highest mountain in the Guayana, and he collected as intensely as ever. While participating in that trip, the expeditionaries were sent supplies from San Carlos de Rio Negro (Venezuela) and Cocui (Brazil) by helicopter, so Julian decided to send his first lot of collections ahead to San Carlos, preserved in formol in plastic bags; but, due to confusion, the plants were un- loaded in Cocui. When Julian returned to Caracas, he realized that a lot of his plants were missing, so in March of the following year he sent me down to San Carlos and Cocui to see if I could find the lost collections and bring them back. When I met the Brazilian officer in charge at Cocui, he told me that he had been there only since January, and that the soldiers, cleaning the warehouse, found a lot of very bad-smelling plants and threw them into the Rio Negro. of the Rubiaceae for the Flora of Venezuela to which I contributed as an artist, and in 1973, when I received my degree at the Central University, I resigned my job at the Botanical Garden and turned to teaching. Julian complained about my decision and told me that he had a lifelong dream to write a flora of the Guayana, for which he would like to employ me as the artist; but at that time I didn't see how it would be possible. Anyway, I kept in contact with him, and from time to time, on the weekends or during vacation, he would invite me to join him on some botanical expeditions, even though at that time he was plagued by arthritis of the hips. As Julian could not walk like he used to, he needed extra help on his collecting trips. In 1973 Julian was asked b agency to make botanical surveys of several coastal y a governmental areas recently designated as national parks, and he invited Victor and me along. We would rent a boat for the day, and Victor and I would go out with a bag and a machete and collect samples from every plant we saw. Then, we would go back to the boat, where Julian cleaned the specimens and put them in his press. In the evening, we returned to the hotel with the plants, and Julian, keeping with his usual routine, worked for hours to number the specimens and to make notes on habit, habitat, and other peculiarities that he observed about the living plants. On the following day when the em- ployees went to clean the apartment, they would complain loudly about the mess. In February 1974, Julian joined the great ex- pedition directed by Charles Brewer-Carias to ex- plore the biggest sinkhole on top of Cerro Sarisa- rinama in southern Venezuela. Victor went with him since he was having difficulty walking at that time. Even with the problems getting around, he managed to collect more than 1,000 plants in 20 days, many of them rare, including 50 new to science. From the bottom of the sinkhole, Charles sent up a pretty little melastome with white flowers and a shaded rose-colored ring around the calyx. It turned out to be a new species that John Wur- dack of the Smithsonian Institution named Phain- antha steyermarkii. For his part, Julian felt so satisfied and grateful with Victor's work, that he named three new species for him: Psychotria car- renoi, Phyllanthus carrenoi, and Sloanea car- renoi. During the several months before the expedition to Sarisarinama, Julian had. been corresponding with people who had had hip operations to correct arthritis problems. They told him that they had felt much better after the surgery, so at last he decided Volume 76, Number 3 1989 Steyermark Recollections to undergo the operation. Since he had to be op- erated on one side first, and then six months later on the other side, he had to stay at home for a whole year. But how was anybody going to convince Julian to rest? That word was unknown to him, and in fact I suspect he was afraid to rest. For that reason, it did not surprise me that he soon found a way to keep busy at home. His good friend Otto Huber had been preparing a list of all of the plants in the national herbarium ever collected on the south slopes of Avila National Park, the mountain that rises above the valley of Caracas to the north. Since Otto was an ecologist, he proposed to Julian that they coauthor a book to be called the Flora of 4vila. Julian was fasci- nated with the idea, but he insisted that the value of such a flora would increase if it also covered the less-explored northern slopes. As he was recovering in a hospital room that had a view of Avila high in front, he was inspired to write the following phrase in the introduction to the flora in reference to me fantastic view of the mountain from the city: e see this beautiful green panorama as we look through the windows of our houses, offices, colleges, hospitals or fac- tories.” Surely when Julian planned the Flora of Avila he had in mind the style of his huge and successful work, Flora of Missouri. Since that was lavishly illustrated, he wanted me to draw as many species as possible in every plate, just like in his previous work. He didn’t want to prepare a strictly scientific work, but one that was usable by many different people. One of the ways that he did this was to insist that the publisher include a metric scale on the back cover, with the hope that the flora would be carried along up the mountain and used on the spot to identify plants. A hopeful assumption, in- deed, but one that demonstrated Julian’s interest in making plants known and loved. So, we began work on the Flora of Avila! I had to make drawings from live material, and then bring them back to Julian to be identified. As the work progressed, he began to complain that I had too many drawings of orchids and other showy plants but few or nothing of several families; and as time passed, we reached a serious impasse. Luckily for us, there was Otto Huber, who could throw water on the flames, and the work went on. It was hard for Julian to type, due to the semireclined position in which he had to remain, so he would turn his manuscripts over to Cora, who was the only person able to read and interpret his thick scratches. Thus she also was a member of the flora team. Julian was later awarded the prestigious "Order of Henry Pittier" by the Ministry of the Environment for the flora. One peculiarity that I observed in Julian's char- acter was that during his fieldwork, he never dared to identify a plant to species, only to genus. For example, once I asked him, “Julian, how do you like that nice Palicourea fendleri?" Immediately he criticized my confidence, which he termed as an expression of ignorance and presumption, and pointed out that P. fendleri was known only from the coastal range of Venezuela, and now we were in the Andes .... Garden in Caracas, would he make a decision on the identity of a plant by checking it against her- barium specimens or sending it to one of his col- Only later, at the Botanical leagues. Once, I told him that I felt that he was too insecure about identifying plants. He answered sharply that he was a scientist and I was only a rank amateur, that ignorance is petulant, and that I should be more careful in my opinions. In those years, Julian also devoted his weekends to a survey of the plants of the wild areas around his neighborhood of Santa Fe, which at that time was being encroached upon by housing develop- ments. That work was later included in a paper by Paul Berry and Julian entitled “Florula of the deciduous forests of Caracas.” As a scientist, Julian was absolutely objective, and he made no statement without proof to back it up; but sometimes, I thought him to be too objective. For example, when we were working on the Flora of Avila, I was fascinated with a beautiful orchid, Oncidium papilio, growing in Julian's gar- den, which in the thirties had been collected to Caracas" according to the label. I argued to him that ^ but Julian cut me short and said that he, as a native show-me-man,” and therefore, "close close to Caracas" might mean "in Avila," of Missouri, was a “* he wouldn't include any species in his treatment if not supported by a more precise collecting locality. But, if I were to make a collection of that orchid from the mountain itself, he would include it in the flora .... I did look for it indeed, but I couldn't find a specimen; that is, until 1985 in the northern side of the national park, seven years after the flora was published. In September 1979, Julian went back to Mis- souri for a couple of weeks for the dedication of the Steyermark Woods. Cora stayed in Venezuela alone in their house, and an American lady who lived close by kept in contact with her and took her to the market whenever she needed to go. Cora felt very uneasy and alone in Venezuela, and Julian was making plans to bring or send her back to Missouri. In fact, since some time earlier, he had 642 Annals of the Missouri Botanical Garden been in contact with Dr. Peter Raven, Director of the Missouri Botanical Garden, and had told him of his desire to write a Flora of the Venezuelan Guayana. Dr. Raven was interested, and they be- gan to consider ways to produce it. Although Julian had become a Venezuelan citizen, he realized that the only way to obtain the help that he needed was to return to the large herbarium in Missouri, and so he made final plans to leave Venezuela with Cora in the spring of 1 All of his careful plans changed abruptly in October of 1983. One night, when he arrived home from the botanical garden, he found Cora tied to a Chair, very scared. What had happened? That afternoon, somebody rang the bell at the entrance and when she opened the door, there were two young men at the gate. One of them pointed a gun at Cora and ordered her to open up. She did as they said, and when they entered, they tied her to a Chair with a blanket and searched the house. They found very few things of interest and soon left, leaving Cora tied to the chair, where she stayed until Julian found her hours later. He called the police immediately, and when the officers arrived, and as a matter of routine, they asked Cora to show them her passport. She went upstairs, still very upset, and on her way back down lost her footing and fell, breaking a bone in her right leg. er leg was set in a cast, and she was released from the hospital, but a couple of weeks later she contracted pneumonia, and a week later, on No- vember 4, 1983, she passed away at age 92. Her last wish to return and see her country again was unfulfilled. I visited Julian frequently in the following weeks. He spoke very little about what had happened, perhaps trying to forget as quickly as possible. He kept busy working and asked me seriously about contributing the drawings for the flora of Guayana that he had planned. In order to motivate me, he placed at my disposition the thousands of color slides he had taken during many years of explo- ration. I started by choosing close-ups of flowers, which would be the most useful for my work; but as I went on, I was impressed by the many beautiful slides of landscapes, and an idea came to my mind: to write a book on the Guayana using many of Julian's slides. So, without telling him anything, I wrote an essay on the history of the search for E Dorado, entitled “En la Tierra del Oro," and added to it 100 of the slides. When I had the manuscript completed, I showed it to Julian, who was at first confused, because he didn't understand that I had tricked him a little bit. Anyway, after he read the manuscript and made some corrections, he agreed that I should carry out the plan and went along with me to an editor, who promised to publish it as soon as possible, though it was not completed until December of 1988, too late for Julian to see - "p In December 1983, I began the drawings for the Flora of the Venezuelan Guayana using the provisional survey of the herbarium in Caracas that Julian made to find out which families were known from the area. In April of 1984, he moved back to his hometown of St. Louis, but only a few months later he came back to Caracas for two or three months to begin checking the herbarium sys- tematically to record all of the plants collected in the area covered by the intended flora. And in February of 1985, Julian was in Caracas again. This time, he had with him a young man, his efficient assistant Bruce Holst, who helped in the general inventory of the herbarium; he was admired for his ability and correct Spanish. Until then, except for the short trip in 1971 in search of Julian's lost plants in San Carlos and Cocui, I had never been on any expedition south of the Orinoco River. Julian wanted to give me an opportunity to see as much of the Guayana as possible now, to help me in preparing the drawings for the Flora by taking pictures, or making draw- ings from live plants, as I preferred. So, in Easter week of 1985, Julian, Bruce, and I headed for the Gran Sabana, in Bolivar State, with the intention of going as far as possible in the ten days that we On that trip, we rented a car called a "Zephyr," a clumsy, two-wheel drive that, when weighed down with all of our gear, barely cleared the ground. Because of the busy vacation week, all of the four- wheel drive vehicles were already rented. On the rough roads of the south, everybody looked at us in astonishment since it was the only two-wheel drive in the whole Gran Sabana, but Bruce man- aged to sort out the numerous ruts in the road and cross the streams to make it all the way to Kamá g the way, we collected mostly along the road since Julian didn't want Bruce or me to go too far into the woods and use up too much time, but we managed to find numerous plants to sketch and photograph that would be valuable for my illustrations. On our way back down to the lowlands, we had a funny incident with a group of university students camped by the side of the road who were in charge of checking the cars returning to the north and helping the tourists with information. As we slowed Volume 76, Number 3 1989 Steyermark Recollections 643 down to pass them, the guard on watch blew his whistle for us to stop, and when he saw some plants that we had in the back of the car, he called for the leader to come out of his tent. He asked for our identification and told us that it was forbidden to remove plants from the Canaima National Park. Julian answered that he was Dr. Julian Steyer- mark, working for the Ministry of the Environment and... “Are you Dr. Steyermark, the author of the Flora of Avila?" he asked in delight. “I have wanted to meet you for many years to congratulate you on such a beautiful book!” Immediately he called all of his helpers to come out and insisted that all of us line up for a picture to be taken with our arms around each other. When the photographer apologized for a delay in taking the picture, Bruce mentioned that there was no hurry since he was standing next to the most beau- tiful girl of the group. In August of the same year, Julian and Bruce were in Caracas once more. On this visit, Julian received his retirement payment and immediately purchased a Toyota Land-Cruiser for use on ex- peditions by both the Caracas Garden and Missouri Botanical Garden. We took it on its maiden voyage to Puerto Ayacucho in the Federal Territory of Amazonas (1-13 September 1985). We had some trouble at the crossing of the Orinoco since a fierce storm was coming up that made the pilot of the ferry think twice about crossing the wide river. But there was a long line of cars waiting, and at last, some people convinced him to make the trip, hop- ing to beat the storm. As soon as we were well out into the river, it started to rain, and big waves splashed over the floor of the ferry, obliging us to take refuge under the covered area. Many pas- sengers began regretting having started the trip, and we were beginning to think that we might not make it to the other side. Apparently Julian was not at all concerned, even though his new car was perched on the front of the ferry, since he sat quietly under the overhang seemingly enjoying the roller coaster. But after one hour or so of being tossed around and getting soaked by the waves, we reached the town of Caicara on the other side. Bruce overheard one of the ferry attendants say that our trip was the roughest that he ever made. On that expedition, I was fascinated by the many strange flowers that we found, especially with a half-dozen species of Mandevilla, a vining genus of the Apocynaceae family with showy yellow flow- ers (a couple of new species would be described later from those collections), and different species of purple morning glories and mallows. Of course, when I saw a pretty flower, I asked Bruce to stop to take a picture; but Julian started getting bothered with so many stops, and he ordered Bruce to follow his instructions, not mine, and to go ahead without stopping any more to make better time. Julian looked very bothered when he said that, and we went on a short time without speaking, all of us feeling tense. I knew Julian as a mild-mannered man, who only on a few occasions would lose his patience, and usually for just a short time. So, I began to tell him in a humble voice: “Julian, sup- pose we see a donkey on a bicycle. Shouldn't that be a reason to stop and take a picture? ...” (No answer). Again, a bit later: “Julian, and if we saw a mammoth flying over that boulder over there, wouldn't it be a good reason to stop and take a picture? . . .” No answer! I understood that maybe went too far with my stupidities, and | decided o shut up and resign myself to his wishes .... Suddenly Julian cried: “Bruce, stop! . . . Bruno, did you see those big yellow flowers in that bush over there? ... Have you already taken a picture of them?" n the way back to Caicara a few days later, Bruce was driving slowly on the muddy road to avoid the many potholes, but Julian asked him to speed up, thinking that when we arrived in Caicara at the hotel, he had to record in his field book all the plants he collected that day. Bruce tried to obey, but when he came across any rut, he would slow down again. At last Julian lost his patience and ordered him to turn over the wheel; and the Land-Cruiser started away at full speed, jumping, splashing, and shaking us up. We arrived at Cai- cara early that evening, and we were the first customers in the restaurant, as was usual with Julian. The following day, early in the morning, we crossed the Orinoco River again, this time with a nice sun and good weather, and by evening we were in Caracas. As a man who loved nature, not only to enjoy it but also to make it known and be loved, he supported with his own money several expensive expeditions to Guayana. He also paid for some botanists from Venezuela to visit herbaria in the United States and for some U.S. botanists to go to Venezuela to work on treatments for his flora. As he was demanding with himself, he used the same standard for others. I was in the office one night when Luis Marcano Berti, a Venezuelan botanist whose trip to the New York Botanical Garden was funded by Julian, called. “Are you also working at 644 Annals of the Missouri Botanical Garden night and on the weekends?" Julian asked. “Yes!” "Oh, very good,” answered Julian contentedly. In my case, although he wanted me to work hard on the drawings, he wished too that I would be able to see and enjoy from time to time the natural beauty of Missouri and especially of the Ozarks. To help me out, he asked Bruce to take me camping some weekend, which we did several times. So, with their help, I was able to get to know some of that wonderful country of Missouri, and also gaze at the stars through Bruce's telescope. Bruce, for his part, would tell me that in late October, when Julian was better, we would all go out again together to see the fall colors, which delighted Julian so much. The weekend after Julian passed away, Bruce took me out to the Ozarks. The sun was bright that afternoon, and the many colors of the falling leaves were spectacular. We regretted that Julian was not with us to enjoy one of his favorite shows of nature. That night, Bruce and I sat a long time looking at the fire. The words came out with difficulty, and several times I had to bite my lips not to weep. Both had lost a great friend, and I missed a man who for me was like a father. At that moment we felt closer than ever before, feeling the responsi- ility we now had to bear of completing Julian's great dream, but glad to have been with Julian in his last hours. A few days later, while writing down these mem- ories, a letter came from Victoriano Carreno, dated Caracas, October 4, 1988. It said: "Dear friend, I heard that you were sick, and I am praying to God for your quick recovery. All of us remembe you, and we hope that you can visit us again... .”” Surely, Julian would have enjoyed receiving this letter with the sincere wishes of Victor, the faithful field assistant who during many years helped him get a bit closer to his dearest dream.— Bruno Manara, Caracas, Venezuela. The return of Dr. Julian A. Steyermark to Mis- souri during the last week in September [ca. 1978] provided me with a chance to talk again to my esteemed friend and to reminisce about my first experiences with him over two decades ago. I had grown up on Steyermark's Spring Flora of Missouri, which I found very useful in adjacent southern Illinois. While I the Missouri Botanical Garden 1 —56, working on my Ph.D. at Washington University, I was constantly reminded of Dr. Steyermark because of his vast collections in the MBG herbarium, because was doing research at 9 of his prodigious writings, and because of the stories retold about him by Edgar Anderson, Bob Wood- son, and others. Following my Ph.D., I began my professional career in the Department of Botany at Southern Illinois University in January 1957. It was my great fortune that during the three-month spring quarter in 1958, Julian Steyermark was offered a Visiting Professorship in the Department of Botany at SIU. The impact that those three months had on my professional career cannot be overstated. Our department at that time was in cramped quarters. | already was sharing a 16 by 8-foot office with Professor John Voigt, the departmental ecologist. Since Dr. Voigt's interests and mine were more closely aligned to Dr. Steyermark's interests, the three of us were crowded into this small office. Steyermark and I spent every day and partway into nearly every evening working side by side. He was putting the finishing touches on his Flora of Missouri and I, along with my wife, Beverly, was revising Jones's Flora of lllinois. Often Steyer- mark would quiz me on some specimen he was working on or sketching. Many species previously unknown by me were quickly and eagerly learned. While much of the three months was devoted to serious botany, Dr. Steyermark would take a little time off now and then to come to our home for dinner. On one occasion he took my wife and me to the local movie theater to see War and Peace. I recall the incident vividly because Julian insisted on picking us up in his vehicle, an Inter- national Scout built high to enable him to negotiate Missouri's back roads. The Scout was so high that I had to climb awkwardly. My poor wife stood helplessly at the door until Dr. Steyermark boosted her up into her seat! One of my most pleasant recollections was an overnight visit to Steyermark's estate near Bar- rington, Illinois, north of Chicago. Julian had talked so often about the wildflower preserve he had built that my wife and | were thrilled to be invited to see it. We arrived early one afternoon. Julian guid- ed us over about half of the property, pointing out with great enthusiasm the many species transplant- ed from the Ozarks. That evening we talked of plants, browsed through his extensive library, and listened to classical music. We awoke the next morning to the delightful smell of bacon frying. Cora, Julian’s wife, hac prepared a feast, including the most delicious baked eggs my wife and I had ever eaten. The rest of the morning was spent walking over the remainder of the grounds before we all began the long drive back to Carbondale. From mid-March to late April 1958, Steyer- Volume 76, Number 3 1989 Steyermark Recollections mark enthralled me with stories of his experiences. I was particularly excited about his rediscovery in 1957 of the very rare and little-known Geocarpon minimum. This species had been found originally in Jasper County [Missouri] in 1913. This re- mained the only known station until Steyermark had rediscovered it in St. Clair County [Missouri] in 1957. My nagging at Dr. Steyermark to show me Geocarpon paid off. He agreed to take Dr. Voigt and me with him on a three-day excursion to see if we could discover additional stations for this dwarf rarity. * We left Carbondale on May 2, heading in the general direction of Springfield, Missouri. Leaving Cape Girardeau, we stopped briefly at the Bollinger Mill and then headed into the Ozarks. Up and down lettered and double-lettered county highways, past shortleaf pine woods, over clear, rock-bottome streams we went, Steyermark pointing out species right and left. We made frequent stops, usually “Wait! There's a county record." I tried to absorb all the after an enthusiastic comment such as species as fast as I could, but Steyermark never relented. We screeched to a halt in Bollinger Coun- ty, pulling off the road next to a steep, wooded cherty slope. Julian asked if any of us had ever seen the little sedge Scirpus verecundus. We re- plied in the negative, and off we went down the slope. Scirpus verecundus was not known from Bollinger County, but Julian was optimistic, saying that this slope looked just right for the little plant. In what could not have been more than five min- utes, the woods echoed Steyermark's voice: “Whee! Over here. I’ve found it!” Scrambling over the treacherous chert, Dr. Voigt and I made it to the kneeling botanist who crouched over a four-inch- tall tuff of green. I had seen my first Scirpus verecundus, and I was never to forget the habitat. Some 15 years later, while exploring in Alexander County, Illinois, I camp upon a similar steep, cherty slope. Recalling my earlier experience, I began to comb the woods and was rewarded by making the first discovery of Scirpus verecundus in Illinois. By late afternoon we had reached Dallas County and were heading along Route 43 when Steyermark observed that the little chickweed on the road shoul- der looked peculiar. On closer look, the plant in- deed was different from anything we had ever seen. We learned later that the plant was Cerastium pumilum, a new record for Missouri. We persisted beyond supper and into the dusk- iness of twilight. By dark, we were still on the road. I began to understand how Steyermark had been able to canvass every square foot of Missouri in 30 years—he never stopped to rest. I saw my first 1958) STEYERMARKMOBILE (ca. IGURE 5. Steyermarkmobile. Contributed by Robert Mohlenbrock. Ozark tarantula, scurrying aross the road in the glow of our headlights. Finally we stopped for camp at about 9:30, reeling from the vast amount of information imparted by Dr. Steyermark. e arose early on May 3 in anticipation of seeing Geocarpon. We had entered Polk County [Missouri] near Graydon Springs when Dr. Stey- ermark announced that we had arrived at a likely looking spot for Geocarpon. It was a glade on a west-facing sandstone escarpment next to Coates Branch, a tributary of the Little Sac River. We quickly found /soetes butleri, Talinum parviflo- rum, and Arenaria patula, species known to be associated with Geocarpon at its other stations. Then, in a small, moist depression on the glade, we spotted it—dwarf, two inches tall, semi-suc- culent. At this stage, the plants were wine-purple. Once we knew what we were looking for, we began to spot another, and another and yet another. Our discovery marked the third known location for Geo- carpon in the world! On the same glade, I also saw for the first time in my life Selenia aurea, Saxifraga texana, and Collinsia violacea. Our spirits were buoyed by these discoveries. We hastened into Green County and stopped at a likely looking sandstone glade near Pearl. We no- ticed Selenia aurea and Saxifraga texana from a distance and, more closely, /soetes butleri. It certainly would be just a matter of time. Sure enough, the wine-purple plants of Geocarpon min- imum became evident after we had wandered into an adjacent glade. I don't recall how many spec- imens there were but I would think there were dozens of them s we were hopping over the glade in our crouched positions, we happened upon a small plant previously unknown from Missouri. It was Scler- anthus annuus, the awlwort of the Caryophylla- ceae. 646 Annals of the Missouri Botanical Garden FIGURE 6. Julian Steyermark. Date unknown. With our success in finding Geocarpon, we headed into Dade and Cedar counties, stopping at several glades. Much to consternation, we couldn't find Geocarpon at any of them. By late afternoon, our we started back to the east where we had planned to camp at beautiful Alley Springs. Darkness caught us again while still on the rolling hills of the Ozarks. The night scarcely slowed Dr. Steyermark as he continued to name roadside plants as our headlights struck them. gon elliottii, " Andropo- ' he shouted once, as we whizzed by a clump of two-foot tall grasses. Most people have trouble identifying this species in the daylight with the specimen in front of them, but Steyermark's identification was right on the money. We got to Alley Springs at last. The long, eventful day was conducive to good sleeping, and I scarcely noted that I was spending the first night of my life atop a hard, slatted picnic table! Next morning we were soon on the road, finding more goodies. About two miles west of Piedmont along Highway 34, we found Cerastium brach y- petalum, the third collection of it in Missouri. Near Cape Girardeau, we discovered our second station for Cerastium pumilum. Since the afternoon was young, Dr. Steyermark expressed a desire to go into Perry County to a deep ravine he had had his eyes on for years. The ravine was new collecting ground for Julian, and he took his plant press with him. He is the only botanist I have ever been in the field with in the United States who carries his press with him. Most of us use plastic bags or tin cans (vascula), and our semiwilted specimens are proof of it. Steyermark had custom-made his own press with a hinged back that opens like a giant book. Our visit to the ravine netted nearly a dozen records for Perry County. We got back to Carbondale early in the evening, finishing a three-day red-letter trip I will never orget.— Robert Mohlenbrock, Dept. of Botany, Southern lllinois University; Ain with per- mission from Missouriensis 1(3): My first meeting with Julian Steyermark was at the Caracas Botanical Garden in 1960, after re- turning from landscape architecture studies at the hode Island School of Design. At that time, there were very few books in Spanish about local orna- mental plants. As a landscape architect, | felt it would be interesting to write a book about tropical trees that would be useful for landscape projects. Gradually, my visits to the Botanical Garden be- came more frequent. Julian was always ready to answer my many questions about trees and other plants, as well as to identify living material that | brought in. In 1963, we made a three-day expedition to the mountains above the coastal town of Naiguatá in a very rich rainforest at 1,000 m elevation and only about 60 km by road from Caracas. We found many new species there including huge trees, and we collected the bromeliad Guzmania sanguinea for the first time in Venezuela. At later dates we went on other trips, and even met at the top of different tepuis with a group from the Terramar Foundation. n 1962, when I began to write and illustrate a color edition of ornamental trees in Spanish, Julian kindly supervised my work. We also main- tained close contact over the next eight years as I worked on my second book called Garden Plants of the Tropics (printed in English and Spanish). Julian wrote the introduction for me. Despite his intensive work in families such as the Rubiaceae, Julian was always intrigued with the beauty and wonderful colors of the Bromeli- aceae. The enchanting forms and the extravagance of the flowers fascinated him, something we cer- tainly shared. I began to fancy the idea of making a book on Bromeliaceae along with him. The first step was to compile photographs, including ones Volume 76, Number 3 1989 Steyermark Recollections 647 Julian occasionally took of the Bromeliaceae on the tepuis. Because of the difficulties of getting to the Guayana, his pictures were particularly valu- able. Soon he agreed to write the text for the book on Bromeliaceae of Venezuela with me. It took about five or six years to organize the text and pictures. From 1980 to 1983, Julian was already very involved with the Flora of the Venezuelan Guayana project, so I decided to do most of the text in order to facilitate his work. I would generally give him eight to ten pages of text to check and translate; he would review these and return them to me after a few days. He was very adept at translating text from Spanish to English and vice versa. Once, Julian became upset with me because, according to him, I was including too many species, and he had no more time to keep reading, cor- recting, and translating. Although there were about 230 species prepared, I went on against his wishes to include a few more that I had collected at the last minute. I insisted that he go over these too. He always wanted to please people, so he did the final effort to finish the last translation and cor- rections for our work. I can still remember hearing him along the corridors of the Botanical Institute saying, “I am very busy with the Flora of the Guayana and have no time to do anything else. Please can you stop adding new data to the book? Our manuscript was handed to the printer just dio before Julian left Caracas to move to St. Louis, but then the book took about two years to be printed. Before leaving his post at the Caracas Botanical Garden, Julian was awarded diplomas and medals together with a reception and a farewell party, by the National Parks Institute in recognition for his tremendous work accomplished in Venezuela. He was most happy and pleased by these honors. After Julian's departure from Venezuela, we kept in touch by mail about the last details and corrections of the proofs of our book. He returned many times to Caracas with his assistant Bruce Holst to work and collect for his monumental Flora of the Ven- ezuelan Guayana. Although he was expecting to finish this project, destiny had other plans.— Fran- cisco Oliva-Esteva, Caracas, Venezuela. Libro de la Sabiduria de Salomon: Mas las almas de los justos están en la mano de acia, y como un aniquilamiento su partida de entre nosotros: mas ellos, a la verdad, reposan en paz. Julián Steyermark no está hoy entre nosotros, pero no podemos decir que está muerto, no podemos decir que ha desaparecido; no existe la muerte para un hombre que hizo tantos caminos. Su obra como su bondad son imperecederas. Su alma se separa de su cuerpo ya inmóvil el sabado 15 de octubre, allá lejos, en tierras norteñas, en la ciudad de Saint Louis. Allá mismo donde nació. Pero la mayor parte de su vida, los mejores años, los pasa con nosotros. o ha habido hombre que haya estudiado más nuestra flora. La pasión máxima de Julián Stey- ermark fue la Guayana, con sus imponentes te- puyes, pero también recorrió con sus ojos bien abiertos a toda Venezuela, viendo y colectando muestras botánicas. Deja una valiosa obra. Era infatigable. Fueron múltiples sus contribuciones: las Rubiáceas, las Pi- peráceas, exploraciones botánicas de las regiones orientales, nuestra vegetación, la Sierra [mataca y altiplanicie Nuria, la flora de la Sierra de San Luis en Falcón, el Cerro Autana, Cima del Macizo Jaua, Cerro Patao en Paria, el Roraima, el Auyantepuy, la flora del Avila. Julián Steyermark fue un excelente botánico. Un incansable admirador de nuestra naturaleza. Coleccionó miles de muestras para herbario. Clasi- ficó una cantidad igual. Atendió centenares de con- sultas. Pero lo más importante es que fue un hombre bueno. Honesto, noble, muy sencillo, extremada- mente sencillo, cordial, amable, siempre dispuesto a responder cualquier pregunta. El gran comple- mento de su erudición era la sencillez. No podemos decir que Julian Steyermark ha muerto. Tal como está escrito en la Biblia: las almas de los justos están en la mano de Dios, y no llegará a ellos el tormento de la muerte eterna. Ellos a la verdad, reposan en Mauricio Ramia, Uni- versidad Central de Venezuela; palabras pro- nunciadas en el acto de apertura del IX Congreso Venezolano de Botánica, el día 13 de noviembre de 1988 en Caracas. Julian took my wife and me for our first look at the Grand Savanna in the Guayana Highland, and with us the Dunstervilles looking for orchids and to whom the place was an old story. As we entered the Grand Savanna, Julian and I stopped on an area of dry open sand and discovered a tiny sundew with one or two sessile flowers in the center of the rosette. Julian named it Drosera felix be- cause of the happy event of our visit. Later on our trip we were camping one night by a small stream, and while Julian was preparing supper, I went out exploring and found an aquatic aroid in a deep pool that the stream had hollowed out of the solid rock. Julian came when he was 648 Annals of th Missouri ES Garden free and with his longer arm was able to collect it. It proved to be a new genus, and George Bunting named it Jasarum, compounding it with Julian's initials and Arum because Julian had discovered so many new genera that such tactics were nec- essary. Later I contributed with the bromeliad Ste y- erbromelia.— Lyman B. Smith, Smithsonian In- stitution. I participated in a number of field trips to Mis- Jr. Steyermark was accumulating vouchers for his flora. The average trip down [from Chicago] was about six hours, and he would con- tinuously quiz me on botanical questions. Typical questions would be: “What type of pla- centation occurs in the Caryophyllaceae?" or “What monotypic genus in the Cruciferae is endemic to the Kerguelen Archipelago?" or “Name all of the phanerogamic genera native to Antarctica." In many cases he was actually thinking about the second question while | was working on the answer to the first one. So you get some idea how many questions were involved on a given trip. would say that he, perhaps more than any other person, stimulated my interest in taxonomic botany.— Floyd Swink, Morton Arboretum. Julian knew Missouri as did few others, and he had a remarkable memory of people, sites, and plants. The Department of Conservation bought the land where Julian found pondberry [ Lindera melissifolia] from a man called O. K. Hamlett. e were discussing this site one day and Julian not only remembered O.K.'s name but he described in detail where several of the rare species were located on the property. I had been on the property a week earlier and Julian talked as if he had — not 25 years before. When the Natural History Section first started to locate and buy significant sites (often with rare or endangered species) we used a list Julian had prepared 20 years before. The same list went into the Natural Heritage Database prepared by The Nature Conservancy and the Department of Con- servation. Thanks to Julian, a number of these areas are now State Natural Areas and protected for those who will come after us. Sand Ponds (the pondberry site), Pickle Springs, and Barn Hollow are exam- ples. Every time we walk in these places Julian's shade will be there too.— John Wylie, Retired Natural History Officer, Jeflerson City, Missouri. Members and friends of the Garden were sad- dened by the death of Dr. Julian Steyermark on Saturday, October 15, 1988. Steyermark was one of the Garden's best-known research botanists, famous locally and around the world for his bo- tanical collections and publications, and for his strong support for conservation of the environment. Born in St. Louis on January 27, 1909, Julian Alfred Steyermark enrolled in 1925 in the Henry Shaw School of B between the Garden and Washington University, where he received A.B. (1929), M.S. (1930), and Ph.D. (1933) degrees. He also earned an degree (1931) from Harvard University. During his early years at the Garden, Julian indulged his other great love, painting watercolors of native flora and plants in the Garden's orchid collection. At that time he began collecting herbarium specimens in Missouri and other states, and by graduation in 1933 he had already surpassed the quantity most botanists collect in a lifetime. After college, Steyermark assisted Robert Woodson, a research botanist at the Garden. This led to his first tropical expedition, a collecting trip to Panama in 1934. He then taught high school in the St. Louis area for two years before moving to the Field Museum of Natural History in Chicago as an Assistant Curator. For the next 21 years Steyermark worked on the Flora of Guatemala and other tropical projects during the week, but continued his Missouri studies in his spare time. A revealing and delightful look at those weekend ex- peditions from Chicago to the wilds of Missouri was provided by his wife, Cora, in her book, Behind the Scenes, published by the Garden in 1984 (and still available in the Garden Gate Shop). efforts culminated in the massive Flora of Missouri 3). This widely acclaimed manual is often re- ferred to as the state's “botanical bible" and has sold out six printings. During World War II, Steyermark was sent to South America as part of the government's pro- otany, a cooperative program These gram to locate new botanical sources for quinine. At that time he first visited the Venezuelan yana region, which he lovingly referred to as *“The Lost World.” (See the Missouri Botanical Garden's Bulletin, November /December 1986 and July, August 1987.) His interest in this picturesque area was so great that in 1958 he left the Field Museum to take a position at Instituto Botánico in Caracas, , Julian returned to the Mis- Gua- Venezuela.

Cora and Julian Steyermark in front of their home at Santa Eduvigis, Caracas, Venezuela, 1965- ~ 1970 ana. This task remains for his friends and col- leagues to complete. Bruce Holst, project coordinator for the Flora of the Venezuelan Guayana, said, “It was a real thrill and a tremendous learning experience to work in the field with Julian. He really had an “eagle eye' for spotting plants, and if you didn't see some- ET = FIGURE 8. thing that he did, he would let you know it . ieldwork was very special for Julian. He never took any ‘vacation,’ he went on field trips instead. He was just so excited about collecting plants, it was impossible not to be caught up by his enthu- siasm. He always likened collecting to a ‘treasure hunt’! Even with his two artificial hips, he would Julian Steyermark on El Avila, outside of UB. Venezuela. Date unknown. 650 Annals of the Missouri Botanical Garden plow through brush, crawl over and under logs, fall down, laugh about it and push on....” Steyermark received numerous honors during his eventful life, including awards and citations from the governments of Guatamala and Vene- zuela, and the 1979 Sierra Club awarded him a special citation for his ardens Henry Shaw Medal That same year, the Ozark Chapter of the conservation efforts, and the Missouri Department of Conservation named the 73-acre Julian A. Stey- ermark Woods, near Hannibal, in his honor. To commemorate Steyermark's achievements, the Garden has established a fund to promote bo- tanical research and expeditions in Latin America, particularly in the Venezuelan Guayana region, and to support research on the natural history of Mis- souri. In addition, the Missouri Department of Con- servation and the Garden are revising Julian's best- known book, which will be retitled Steyermark's Flora of Missouri, a lasting memorial to a giant among botanists. FIGURE 9. (holding papers). A memorial service was held for Julian Stey- ermark at the Garden on October 25, 1988. In the eulogy, Dr. Raven said, . His last work will be completed here, and will stand as a final tes- tament to his industry and to his scholarship. As for any human being, however, what will prove to be even more important to all of us will be our memories, for Julian Steyermark was an inspira- tional person, one who projected his own values without trumpeting them, and thereby enriched all our lives, as he did the literature of botany.” George Yatskievych heads the Garden's joint project with the Missouri Department of Con- servation to revise Steyermark's Flora of Mis- souri.— Luther Raechal assisted Dr. Steyermark on the Flora of the Venezuelan Guayana and is continuing his work on the staff of this ongoing project; reprinted with permission from the Bul- letin of the Missouri Botanical Garden 77 (1): 5 1989. : a 4 M. e V Im Geoffrey C.

Julian Steyermark. PLANT TAXA DESCRIBED BY JULIAN A. STEYERMARK' Mary Susan Taylor? ABSTRACT In his 62 years of actively collecting plants (1925-1987), Julian Steyermark described 2,392 taxa, including 1 family, 38 genera, an species. He named plants ountries and from 16 states in the U.S.A. Types om 26 c s fr of taxa that he named are listed alphabetically by family, with author, literature citation, collector, collection number, date of collection, locality, elevation, and depo names, SAS names, and some include are oe ed. sitory. comme current nomenclature (which are not referenced in the bibliography). Appendices nymy, collectors index, and family index. The bibliography includes 395 references. Statistical summaries nts are supplied, where pertinent, on never-published Julian Steyermark collected his first plant in 1925, his last in 1987, both in Missouri. He col- lected so many plants, over 130,000 collections, that he received recognition from the unusual source of the Guinness Book of World Records. Julian was most known for his Flora of Missouri, and his work in Guatemala and Venezuela, yet he described plants from 26 countries and from 16 states in the His statistical record is astonishing. Julian Stey- ermark described a single family, 38 genera, and 1,864 species. Including other ranks, he named at least 2,392 taxa. Taxonomic Literature (second edition) cites an as yet unobtainable reference edited by H. Villanueva, 1977 (Bibl. Alfredo Jahn, Bol. Inf. 9: 9-12) which purports to contain the ‘most important of over 350 publications’ by Julian Steyermark. It is estimated by the present author that this compilation lacks about 80 references, although the exact number is unknown. In the list of types families are arranged alpha- betically, and species alphabetically within families, then by descending rank within species. Data in- clude the name, author(s), place of publication, collector, collection number, date of collection, lo- cality, elevation, and depository. Current nomen- clature (which are not referenced in the bibliog- chiche, Quebrada Jac olini umbrosa (Benth.) S. F. Blake raphy) and accession number of the Missouri Botanical Garden sheet are indicated when found serendipitously. New combinations are not includ- ed.

Hernández? (LEGUMINOSAE)! ABSTRACT Zapoteca (Leguminosae: Mimosoideae) is a si ies well- Veces genus belonging to the tribe Ingeae distributed from the southwestern United States and northern Mexico to Piin Argentina and the West Indies. The highest concentration of taxa occurs in the dry ben of so aod n Mexico and, to a lesser extent, in Central America and the northern Andes. The predominance of allopatric distributions and the apparent low frequency of hybrids suggest that r in this genus has primarily arisen from genetic differentiation of a isolated populations. The recent climatic episodes of the dulce appear to m had a prominent role on the current distributional patterns of Zapotec a species. Zapoteca species have similar reproductive biologies. All probably have nocturnal anthesis and are pollinated by ad settling moths. Self-compatibility appears to be widespread in the genus, Z. tetragona being the only known self-incompatible species. Andromonoecy is another widespread component of the breeding system of Zapoteca species. This probably maximizes the use of reproductive energy without reducing pollinator attraction. The basic chromosome d of Zapoteca (x = 13) and some of the generalized characters of the polyads (i.e., acalymmate, discoid, 16-grained polyads) indicate a relationship between Zapoteca and the remaining genera of the Ingeae, with the exception of Calliandra sensu stricto, which is cytologically and morphologically isolated in this tribe. I recognize 17 species in Zapoteca, three of which (Z. alinae, Z. andina, and ana) are newly described. Eleven subspecies are recognized, of which Z. portoricensis subsp. pubicarpa is newly described. A subgeneric classification is proposed, where taxa are grouped into four morphologically distinct subgenera: Nervosa, Zapoteca, Aculeata, and Amazonica. The subgenera are based primarily on differences in vegetative characters: number of pairs of pinnae, number of leaflet pairs per pinna, leaflet size, leaflet texture, venation patterns, and stipule type.

Los episodios climáticos recientes i Pleistoceno posiblemente tuvieron un papel determinante sobre los patrones de distribución actuales de las especies de Zapoteca. Las especies de Zapoteca son bastante uniformes en los rasgos generales de su biología ra Todas tienen posiblemente flores con antesis nocturna y son polinizadas por palomillas no especializadas. Los sistemas de auto-compatibilidad genética parecen estar bién representados en el género, Z. tetragona siendo la única especie en donde la auto-incompatibilidad ha sido demostrada. La andromonoecia es otro componente común de los sistemas reproductivos de las especies de Zapoteca; este fenómeno se a como un medio para maximizar el uso de la energi ia reproductiva, sin re 'ducir la atracción a los polinizadores. El número cromosómico básico de Zapoteca (x = 3), en asociación con algunos caracteres generalizados de n políades (ej., políades acalimadas, discoides, con granos), reflejan relaciones entre Zapoteca y el resto de los géneros de la tribu Ingeae, con la excepción de Calliandra sensu stricto, género que es fuertemente atípico desde el punto de vista citológico y morfológico. En este trabajo se para la cier ‘ T como nueva. En base a los patrones de variación en caracteres vegetativos (ej., número de pares de pinnas, nümero res de foliolos por pinna, tamano de los n textura de los foliolos, patrones de vanación de los foliolos y tipo de estípulas) se propone una clasificación subgenérica, en donde las especies se agrupan en cuatro subgéneros distintos: Nervosa, Zapoteca, Aculeata y Amazonica. o Zapoteca (Leguminosae: Mimosoideae) is a ge- Laetevirentes.

Zapoteca portoricensis subsp. flavida and Z. amazonica grow in moist thickets supported by neighboring shrubs. Similarly, Z. caracasana branches near the base of the primary stems and has spreading branches that become prostrate or subprostrate. The scandent and prostrate habits are found exclusively in warm, moist habitats. Leaves. The leaves of all species of Zapoteca are stipulate and twice pinnate with opposite leaf- lets. The wide variation in leaf characteristics pro- vides an excellent basis for classifying members of the genus. Mature leaflets vary in length from about 0.5 em in Z. alinae and Z. media to a maximum of 22 cm in Z. amazonica. In addition, there is a clear tendency towards a reduction in number of leaflets concomitant with an increase in leaflet size. In all species of subg. Zapoteca the pinnae have from several to many pairs of leaflets; by contrast, in Z. amazonica the leaves have only one pair of pinnae with a single pair of large leaflets. Fur- thermore, all members of subg. Zapoteca have relatively membranous leaflets, whereas in the re- maining species they are clearly chartaceous to coriaceous. Extrafloral nectaries are uniformly present in Z filipes, Z. scutellifera, and Z. nervosa. They are located between the insertion of the pinnae and, less frequently, between the distal pairs of leaflets. In Z. scutellifera and Z. filipes an additional nec- tary is located near the base of the petioles. The nectaries are more or less cup-shaped in Z. scu- tellifera and Z. nervosa and cylindrical in Z. fi- lipes. According to Zimmerman's classification 1983), all of these fall into the "Hochnek- category (elevated nectaries). Extrafloral nectaries have long been considered to be the focal (Elias, tarien point of a mutually beneficial relationship between the plants that possess them and certain groups of ants (see summary in Bentley, 1977). The ants exploit the nectar produced by these glands, which is rich in sugars, amino acids, proteins, and other 1983) and provide the plant varying degrees of antiherbivore protection. However, such a relationship has not yet been demonstrated in Zapoteca. compounds (Elias, with lenation patterns.

In this section of Zapoteca, in order to obtain a broad picture of the variation of this important component of the leaf architecture. Mature leaflets of ten species of Zapoteca, rep- resenting all the subgenera (Table 3), were cleared following Dilcher (1974). The terminology follows Hickey (1973, 1977). Variation in leaflet venation patterns is highly consistent with the subgeneric classification in Za- poteca and provides important information for phy- logenetic interpretation. All members of the genus The secondary veins usually depart from the primary essentially have brochidodromous venation. vein at an acute to right angle, curving abruptly to join superadjacent secondaries to form a loop. In addition, loops are always enclosed by arches formed by higher-order veins. Zapoteca nervosa differs from the remaining examined species in having eucamptodromous venation in the basal half of each leaflet and brochidodromous venation in the upper half (Fig. 30). Furthermore, the tertiary domains in the leaflets of this species are elongate and parallel to the primary vein, and the free- ending veinlets are more abundant in the distal area and usually are once- or twice-branched. The marginal venation is looped in all Zapoteca species with the exception of subg. Amazonica, where it is clearly fimbriated. Similarly, all species of the genus have incompletely closed areoles, ex- cept Z. amazonica and Z. microcephala, which have imperfectly developed areoles. With the exception of Z. tehuana, all species of subg. Zapoteca are characterized by relatively fine, inconspicuous tertiary and higher-order veins that are difficult to discriminate even under a dis- leaflets of Z. te- huana and all species of the other subgenera (Table secting microscope. By contrast, 3) have thicker and conspicuous tertiary and qua- The vena- tion patterns of Z. tehuana (subg. Zapoteca) and Z. aculeata (subg. ternary veins and free-ending veinlets. 1culeata) are strikingly similar, reflecting taxonomic affinities between the two sub- genera. These two species share the basic brochi- dodromous venation pattern of the genus; however, they differ in their marginal venation and in the orientation of their high-order veins and veinlets. Although the marginal venation of these two species is clearly looped, occasional free-ending marginal veins are present. The veinlets are characteristi- cally oriented towards the admedial-basal area of the leaflets in these two species. Zapoteca amazonica and Z. microcephala have several characters in their leaves that depart from the rest of the genus. The tendency towards the development of larger leaflets concomitant with a reduction in their number in these species is prob- ably associated with an increase in the degree of organization of leaflet venation.

The venation patterns of the two species of subg. dmazonica reflect an advanced condition because their tertiary veins have relatively regular courses (third rank; see Fig. 48). In contrast, the leaflets of the re- maining species of Zapoteca fall in the second rank because their tertiary and higher-order veins are random in course and are usually not well differ- entiated from the lower orders. Of particular in- terest is the presence of two co-primary veins (Fig. 48) in the leaflets of Z. amazonica and Z. micro- cephala. This probably indicates leaflet. fusion. Hickey & Wolfe (1975) reported that leaflet fusion is a common tendency in the Leguminosae. Leaf pubescence. With few exceptions, pu- bescence type is not a reliable taxonomic character in Zapoteca, because in most of the species it is clearly variable within and between populations. Zapoteca nervosa, Z. aculeata, Z. amazonica, and Z. microcephala appear to be uniformly en- tirely glabrous or nearly glabrous, whereas Z. mol- lis is consistently pubescent throughout.

The flowers are consistently arranged in compact, homomorphic, spherical, capitate inflorescences. In the basic plan of inflo- rescence organization, solitary or fasciculate pe- duncles are axillary and subtended by a leaf, as in Z. alinae, Z. media, and Z. aculeata (Fig. 7A). indication of the derived character of the There is, the progressive reduction of the subtending leaves, however, an evolutionary trend toward which reaches its extreme in the two species of subg. Amazonica, where the leaves are always vestigial, and the inflorescence therefore appears to be an elongate panicle (Fig. 7D, E). Transitional forms between the two extremes are found in several species of subg. Zapoteca (Fig. 7B). For instance, in Z. mollis, Z. portoricensis, and ad- ditional species, the subtending leaves start deve- loping during or after anthesis.

The paniclelike inflorescences of Z. microcephala and, especially, Z. amazonica (subg. Amazonica) are highly modified and are clearly derived from the basic type. Intermediate types exist in many species of subg. Zapoteca, where a single individual may have both leafy, axillary ca- pitula and flowering branches with vestigial or late- developing subtending leaves. Flowers. | Aside from variation in size and in the relative proportions of their parts, the flowers of Zapoteca species are extremely constant. De- tails of floral morphology and certain aspects of floral biologv are in the generic and specific. de- scriptions and in the section on reproductive bi- ology. POLLEN The diversity of pollen types in subfamily Mi- mosoideae has been studied extensively by several authors (Guinet, 1969, 1981— a review; Sorsa, 1969; Niezgoda et al., 1983). One of the outstand- ing features in this subfamily is the high frequency of permanently compound grains, these either in tetrads or more commonly in polyads. As Guinet (1981) and others pointed out, the basic polyad type in the Mimosoideae is the acalymmate type, in which the individual grains are more or less free from one another. This form of polyad cohesion is in contrast to the calymmate type, where the ex- ternal layer of the exine is common to all cells. Calymmate polyads are found in Calliandra. 1986a), several comprehensive surveys on the pollen char- acteristics of Calliandra (Guinet, 1965, 1969, 1981; Guinet & Barth, 1969; Sorsa, 1969; Niez- goda et al., 1983) indicate the phyletic distinctness As discussed elsewhere (Hernandez, of Zapoteca. The basic plan of polyad organization here is the same as that in the other genera of tribe Ingeae, but unlike that of Calliandra sensu stricto. All the species in the genus have acalym- radially symmetrical, l6-grained mate, discoid, polyads (Figs. 8-13). The eight central grains, which are distributed in two rows, are morpholog- ically different from the peripheral grains (i.e., the pollen grains exhibit heteromorphy). The external layer of the exine has an undifferentiated granular structure, and the individual grains is al apertures (see fig. 7 83). The size of the polyads ranges from 76 to 2 um. in Niezgoda et al., One very striking diagnostic character, found no- where else in Mimosoideae, prominent lens-shaped structures in the. central cells on one side of the polyad. These are found is the occurrence of connection with this, Guinet (pers. comm., 1985) observed that the rounded lens-shaped areas occur on both sides of the polyads (on eight grains) in Z. aculeata and Z. amazonica; nevertheless, they are less pronounced on one side. Such areas some- times occur on some or all of the peripheral grains of Z. alinae polyads (Fig. 9 PODS, SEEDS, AND SEED DISPERSAL Pods. throughout Zapoteca (Figs. 14, 15). The pods are Pod morphology is relatively. constant usually straight, linear, and flattened: they gen- erally have unconstricted margins, visible seed chambers, and thickened sutures (terminology fol- 1984). Pod size varies from 3.5 x 0.7 cm in Z. formosa subsp. mollis to 24 x 1.2 lowing Gunn, em in Z. amazonica. There is some interspecific variation in the texture (density) of the valves, which is of taxonomic value. In this respect, the species may be arranged into three groups: 1) Le lambertiana and Z. filipes with thin, membranous valves; 2) the remaining species of subg. Zapoteca, along with Z. nervosa, with thick, membranous valves; and 3) Z. aculeata, Z. microcephala, and Z. amazonica, with coriaceous valves.

Seeds. In all species of subg. Zapoteca, the seeds are widely ovoid to rhomboid and compressed and lack rupture lines, arils, or wings (Figs. 16, 17). In most members of this subgenus the testa is mottled, or dichrome, in which case the area encompassed by the pleurogram (areola) has a lighter color than the outside area. There is con- siderable interpopulational variability in seed size and the coloration of the testa, especially in Z. formosa; by contrast, Z. tetragona appears to be consistent in having dark, monochrome, ovate seeds. Another seed feature is the pleurogram, common 1984). Seeds of subg.

Seed dispersal. | Zapoteca pods dehisce ex- species of Zapoteca over land and is probably plosively with the valves splitting along both sutures effective over larger distances as a result of ac- from apex to base (Fig. 15).

Scale bars = 2 cm This dispersal mechanism, however, does not explain the presence of species such as Z. formosa, Z. caracasana, and Z. portoricensis on islands, which they presumably reached by long-distance dispersal over water. Zapoteca formosa, for in- stance, occurs throughout the West Indies and on some islands off the Mexican Pacifice coast (Revilla- gigedo Islands). Populations of this variable species frequently grow in coastal areas. Although exper- iments have shown that seeds and mature pods of Z. formosa subsp. formosa taken from a coastal population of the Yucatán Peninsula floated for only two to four days in seawater, the seeds are highly resistant to saline water. As shown in Figure 18, seeds from this population (Hernández 940) germinated after soaking in saline. water (3.4% sodium chloride) for up to 70 days. Most of the seeds germinated normally when they were me- chanically scarified and transferred to petri dishes in a medium moistened with fresh water.

SEEDLINGS The taxonomic importance of seedling charac- ters has been recognized by legume researchers for a long time (De Candolle, 1825; Compton, 1912). Recently, such characters have been ap- plied | successfully in the construction of generic classifications in Leguminosae (Léonard, 1957; Vassal, 1969; der Schiff, 1971; Kupicha, 1977; Guinet et al., 980: and others).

In this connection, it is reasonable to hypothesize that Z. nervosa represents an Efe line that separated from the main stock early in the evolution of the genus, and its peculiar morphological features would be explained by divergent evolution. The lack of are- olate, lens-shaped thickenings in the polyads of Z. nervosa, a character also absent in the remaining genera of the Ingeae, appear to represent a prim- itive condition within Zapoteca and suggests that this species is phylogenetically basal in this genus. Additional information on this critical species is needed in order to learn more about its phyloge- netic relationships. Subgenus Zapoteca is the most widespread and diversified subgenus in Zapoteca. Yet a number of morphological features common to all the species All the species have pinnae with several to many pairs of make this subgenus easily recognizable. thin, membranous leaflets, which show character- istic usually inconspicuous and simplified venation patterns. The highest diversity of hair types (three types) of the genus is found in subg. Zapoteca; the species of the remaining subgenera are char- acterized by having only the unicellular conical type (Table 4). Further, the valves in the pods in subg. Zapoteca, along with Z. nervosa, are con- sistently thick-membranous, whereas those of subg. Aculeata and Amazonica are coriaceous. The pattern of leaflet venation Z. tehuana differs from those of the other species in subg. Zapoteca and shows strong similarity with those Aculeata). of Z. aculeata (subg. This may indicate a phylogenetic link between the two subgenera. Subgenus Aculeata contains only Zapoteca aculeata, which is characterized primarily by spi- nescent stipules (a characteristic that has clearly been derived within the genus), by an apparent arborescent habit, and by pinnae having fewer pairs of chartaceous-coriaceous leaflets than those of subg. Zapoteca. The coriaceous pods of Z. acu- leata resemble those of subg. Amazonica. Subgenus Amazonica is made up of Z. ama- zonica and Z. microcephala, which are charac- terized by having the most obvious combination of apomorphic features in Zapoteca. Their leaves are reduced to two or three large, coriaceous leaflets in each pinna. This is the result of an evolutionary trend toward reduction in the number of leaflets associated with increased leaflet size. This trend is also seen in other genera of Mimosoideae (e.g., Moreover, the leaflets in Calliandra, Mimosa). these species have a number of common architec- tural features reflecting an increased level of or- ganization, which is also interpreted as an advanced condition. A progressive trend toward suppression of leaves subtending the inflorescence in Zapoteca has resulted in the highly specialized, elongate pseudopanicles of these species. Among other clearly apomorphic features of subg. Amazonica are the elongate seeds of Z. amazonica, which lack the characteristic pleurogram and are the largest in the genus. BIOGEOGRAPHY Zapoteca ranges from the southwestern United States (southern Arizona and southwestern Texas) and northern Mexico, from about latitude 32°30'N, southward through most of Mexico, Central Amer- ica, and much of South America (Venezuela, Co- lombia, Ecuador, Peru, Bolivia, Guyana, Brazil, Paraguay) to Argentina (ca. 2:7°30' "si Zapoteca also occurs on most of the northern latitude West Indies and in the PLE Islands (1.e., Isla Socorro and Isla Clarión Zapoteca species occur in a variety of environ- ments, ranging from open, arid or semiarid, scrub- by vegetation types (e.g.. Z. media, Z. alinae, Z. formosa subsp. mollicula, and Z. formosa subsp. schottii) to the wet evergreen forests of Amazonian Peru (Z. amazonica). Most populations of Z. por- flavida and Z. found in relatively wet, lowland habitats, generally toricensis subsp. tetragona are on disturbed sites. The greatest degree of diver- sification has occurred in areas covered by sea- sonal, tropical deciduous forests (sensu Breedlove, 1981). In addition to the species found in clearly arid regions, most populations of eight species of Zapoteca (Z. nervosa, Z. lambertiana, Z. filipes, Z. mollis, Z. caracasana, Z. andina, Z. formosa, and Z. tehuana) occur in tropical deciduous for- ests. In addition, Z. portoricensis subsp. portori- censis and subsp. pubicarpa primarily occur in oak, montane moist forests. The occurrence of three of the four subgenera middle-elevation pine-oak, or subtropical of Zapoteca in South America (Zapoteca, Acu- leata, and Amazonica), compared with only one in Mexico and Central America, is probably a con- sequence of the more ancient existence of Zapo- teca in South America. Although only subg. Za- poteca is represented in Mexico and Central America, extensive diversification has taken place at the specific and subspecific levels, especially in Mexico. For instance, there are seven subspecific taxa in Mexico (i.e., Z. portoricensis subsp. por- toricensis, Z. portoricensis subsp. pubicarpa, Z. Volume 76, Number 3 Hernández 795 1989 Zapoteca portoricensis subsp. flavida, Z. formosa subsp. casana, Z. tetragona, Z. costaricensis, Z. for- formosa, Z. formosa subsp. rosei, Z. formosa subsp. mollicula, schottii), four « In contrast, Z. formosa subsp. them restricted to this country. only four subspecies of subg. Zapoteca occur in all of South America (Z. portoricensis subsp. flavida, Z. caracasana subsp. caracasana, Z. caracasana subsp. weberbaueri, and Z. formosa subsp. for- mosa), and only one of these, Z. caracasana subsp. weberbaueri, is endemic Viewed from a global perspective, there are no clear centers of species diversity in Zapoteca. The total number of species and the number of endemic species are roughly correlated with the size of each region (i.e., Mexico, 7 species/4 endemics; Central America, 6/2; West Indies, 4 10/6. the areas of species concentration and the distri- l; and South Amer- ica, However, a more detailed analysis of bution of endemic taxa ee several regions with high diversity (Fig. Southern Mexico ee a -— Chiapas, includ- ing southern Puebla) has the largest concentration of species and subspecies of Zapoteca. This rela- tively small region, characterized by its remarkable climatic and topographic diversity, contains seven species, and if subspecies are taken into account, the figure rises to eleven taxa (Z. media, Z. alinae, Z. lambertiana, Z. portoricensis subsp. portori- censis, Z. portoricensis subsp. pubicarpa, Z. por- toricensis subsp. flavida, Z. tetragona, Z. formosa subsp. formosa, Z. formosa subsp. rosei, Z. for- mosa subsp. mollicula, and Z. tehuana). Four of these are endemics (Z. alinae, Z. portoricensis subsp. pubicarpa. Z. formosa subsp. mollicula, and Z. tehuana). especially to dry areas of Oaxaca and the arid valleys of the Pueblan- Oaxacan bor- der region. The number of species and subspecies of Zapoteca suddenly decreases from this center Fig. 21). On the Pacific slope of Mexico, from Guerrero northwards, there are four — in all directions taxa (Z. tetragona, Z. formosa subsp. formosa, Z. formosa subsp. rosei, and Z. formosa subsp. schottii), decreasing to one in the northern portion. Zapoteca media and Z. formosa subsp. formosa are the only taxa that occur in the Central Plateau. Along the entire Atlantic slope, from Tabasco to Tamaulipas, together with the Yucatán Peninsula, there are only five taxa (Z. lambertiana, Z. por- toricensis subsp. portorte ensis, Z. portoric ensis subsp. flavida, Z. tetragona, and Z. formosa subsp. formosa). Zapoteca lambertiana is the only one of these that is essentially endemic to this region. In Central America, there are a total of eight taxa (Zapoteca portoricensts subsp. portoricensis, Z. portoricensis subsp. flavida, Z. mollis, Z. cara- © — mosa subsp. formosa, and Z. formosa subsp. sal- vadorensis). Diversity is quite uniform among the different countries (Fig. 21). Zapoteca mollis and Z. costaricensis are essentially endemic to Costa Rica, although a disjunct population of the former is known from Panama. Zapoteca formosa subsp. salvadorensis is restricted to southern Guatemala and El Salvador. Six taxa of Zapoteca occur in the West Indies (Z. nervosa, Z. portoricensis subsp. portoricensis, flavida, Z. subsp. caracasana, Z. formosa subsp. formosa, Z. portoricensis subsp. caracasana and Z. formosa subsp. gracilis). Generally only a single species occurs on a particular island; how- ever, in Hispaniola the four species, including the endemic and morphologically distinct Z. nervosa, occur together. Howard (1973) pointed out that Hispaniola and Cuba are the most floristically di- verse islands in the West Indies and that they show great habitat diversity and highest percentage of endemism (Hispaniola with 33% of endemic gen- era). Zapoteca formosa subsp. gracilts is the sec- ond endemic entity in the West Indies. It is pri- : the Bahamas, Cayman Islands, and northwestern Haiti. marily restricted to coastal areas in Cuba, Eleven taxa of Zapoteca occur in South Amer- ica. The greatest diversity occurs in the tropical Andean countries, Venezuela, Colombia, Ecuador. Peru, and Bolivia, where populations are primarily found in the foothills of the Andes, in the inter- Andean valleys, and less commonly in the Amazon Basin. As illustrated in Figure 21, the number of taxa in each of these countries ranges from four to six, with Colombia and Ecuador most diverse. Perhaps the most remarkable biogeographical fea- ture of this whole area is the occurrence of five endemic taxa, which, excluding Z. caracasana subsp. weberbaueri and Z. andina, comprise the most highly advanced species in Zapoteca, each with a large number of derived morphological char- acters (i.e. Z. Andes; Z. the Magdalena aculeata, Ecuadorean microc suada, Median Valley of River; and Z. amazonica, Amazonian Pe ru). Out- side this area, diversity is much lower, with one or two taxa oceurring within Guyana, Brazil, Para- guay, and northern Argentina (Fig. 21). Within however, there are two extra- £. filipes, restricted to the Brazilian states of Goiás and Minas Z. scutellifera. found in the states of Amazonas, this large region, Andean endemic species: Gerais, and Para and Rondonia, Brazil, and in the departments of El Beni and Santa Cruz, Bolivia.

Number of Zapoteca species and subspecies per country. Mexican regions and Brazilian states are treated as separate units. Total number of taxa/endemic taxa. number of cases of gross geographical overlap are known. However, only a few records of true sym- patry exist: in the District of Tlacolula, Oaxaca, plants of Z. alinae (H. Hernández & Ramírez 942) have been found intermixed with plants of Z. formosa subsp. rosei (H. Hernández & Ramírez 943); in this same area of Oaxaca, Z. formosa subsp. formosa has occasionally been found grow- ing alongside Z. formosa subsp. rosei (H. Her- nández & Torres 216, 217 and Magallanes 111, 113). Also, in the tropical deciduous forest of El Chorreadero, Chiapas, Z. lambertiana (Breedlove 39694, H. Hernández & Ramírez 891) and Z. portoricensis subsp. portoricensis (Breedlove 11889) have been collected; however, it is unclear whether these are narrowly sympatric. There are some presumed hybrids. For example, in southern Guatemala and in southern Mexico, a number of collections provide evidence for exten- sive hybridization between Z. portoricensis subsp. portoricensis and Z. tetragona; in southern Puebla and northern Oaxaca, some plants with characters intermediate between Z. media and Z. formosa likewise suggest hybridization. In Guerrero popu- lations of Z. formosa subsp. formosa and Z. for- mosa subsp. rosei come into close proximity, and there are a number of collections of probable hybrid origin. The predominance of allopatric distributions and the apparent rarity of hybrids in Zapoteca suggest that hybridization has played an insignificant role in the evolution of the genus. The few cases of strict sympatry may represent secondary contact of previously differentiated populations. It could be hypothesized that speciation in Zapoteca has pri- marily resulted from genetic differentiation of geo- graphically isolated populations. There are wide disjunctions in the distribution of Z. formosa subsp. formosa in South America, from northern Colombia and Venezuela to Bolivia, southeastern Brazil, and Paraguay (Fig. 44). As elaborated below, its distribution was probably con- tinuous across the Amazon Basin during the cool- dry phases of the Pleistocene, when a drier and presumably more suitable environment for this sub- species was widespread (Ab'Sáber, 1982; Absy, 1982; Bigarella & Andrade-Lima, 1982; van der Hammen, 1982; Prance, 1982). Zapoteca scu- Volume 76, Number 3 Hernández 797 1989 Zapoteca tellifera is closely related and is known from a few — et al., 1980), and also by the wide distribution of disjunct populations in the Amazon Basin (Fig. 44). Specialized characters in Z. scutellifera (e.g., scu- telliform extrafloral nectaries, scandent habit) and its presumed edaphic specialization suggest that it was probably derived from Z. formosa subsp. for- mosa. Zapoteca scutellifera could have been de- rived from populations of Z. formosa subsp. for- mosa that became isolated after the return to the present-day, warm-wet climatic conditions. This pattern. along with the patchy distributions of dry-forest species like Z. E Tllana and mollis, supports Gentry's (1979, 2) theory of reverse refuges. This theory assumes that the pres- ent discontinuities in the distribution of the dry forests (dry forest refuges) coupled with the exis- tence of geographically restricted, morphologically differentiated dry-area populations, result from a shift towards more mesic conditions after the cli- matic deterioration in the Quaternary.

Furthermore, most species of Acacia (Acacieae) are insect-pollinated (Bernhardt, 1983; pers. obs.); however, bird pollination has been derived second- arily in some Australian species of this genus (Ford & Forde, 1976; Bernhardt, 1983; Kenrick et al., 1983). In contrast, Parkia (Parkieae) is primarily bat-pollinated (Baker & Harris, 1957; Hopkins, 1984), although a few species are pollinated by g | I ) insects (see discussion in Hopkins, 1984) High-energy pollination systems such as those involving hawkmoths. birds, and bats are concen- trated among the genera of the more advanced tribe Ingeae (Cruden et al., 1976; Arroyo, 1981; 1983; Hernández, 1986a; unpublished obs.). In the Ingeae, the transition from low-energy Koptur, insect pollination to high-energy systems, which demand greater allocation to nectar and pollen, is associated with inflorescence modifications. For in- stance, connation of the staminal filaments to form a tube and increase in number and length of the filaments made it possible for the flowers to hold larger quantities of nectar necessary to satisfy the energy requirements of larger, homothermic pol- linators. Similarly, changes in periodicities of nectar and aroma production, nectar quality, and timing of anthesis have enabled the plants to adjust to the physiological and behavioral characteristics of par- ticular pollinators. Mimosoideae have a number of additional productive traits that make them extremely inter- esting from an ecological and evolutionary point Guinet (1969, 1981) that the most conspicuous pollen is the occurrence of permanent units of of view. discussed in detail feature of mimosoid dispersal in the form of tetrads, octads, and polyads throughout the subfamily.

Viewed in an evolutionary perspective, these reproductive phenomena have great potential as characters on 798 Annals of the Missouri Botanical Garden which to base phylogenetic interpretations. Pub- lished reports concerning the reproductive biology of the species here assigned to Zapoteca are vir- tually nonexistent, and the present chapter is in- tended to provide an account, based on my own observations, of some of the reproductive features of these plants. METHODS Nectar volumes were measured with calibrated micropipets, and sugar concentrations were deter- mined using a temperature-compensated Erma hand refractometer. In a few cases, when the flowers were very small, a syringe was used to extract the nectar from the staminal tubes. All measurements were made in the greenhouse early in the morning in order to estimate the total amount of nectar produced per flower. Between four and ten indi- viduals per population were examined. It is quite possible that the results in Table 6 might be lower volumes than would be found in the wild, since it has been shown that nectar volumes and sugar concentrations may be significantly lower in plants growing in greenhouse pots compared with wild plants (Cruden & Hermann, 1983). However, they allow species comparisons. Field observations on flower visitors were carried out continuously during the first three to five hours of anthesis. Since all Zapoteca species flower at night, the behavior of flower visitors was observed with the aid of a head lamp. In most cases, visitors were successfully collected with insect nets. Insect voucher specimens are deposited in the Entomo- logical Collection at the Instituto de Biologia, The number of ovules per gynoecium was de- termined by squashing fixed ovaries in a drop of Alexander's stain (Alexander, 1969); the ovaries were examined with a compound light microscope within 15-20 minutes after staining. Sex expres- sion was characterized for each population by dis- secting fixed flowers and counting the proportion of hermaphrodite and female-sterile flowers in each inflorescence. Self-compatibility was assessed on plants growing in the greenhouse using the tech- niques outlined by Bawa (1974). Pollinations were accomplished using a fine brush within four hours of the beginning of anthesis, once the anthers were dehiscent. Anther dehiscence was determined by touching the anthers with a clean microscope slide; a large number of polyads on the slide revealed open thecae. Given the small size of the flowers, the inflorescence was taken as a unit in the polli- nation treatments. In every population, a deter- mined number of inflorescences were artificially eross- and self-pollinated, and several additional inflorescences were left untreated (open) to test for autogamy. Due to the difficulty involved in emas- culating the delicate flowers of Zapoteca, the pos- sibility of apomixis was not tested. For the cross- pollinations, mixtures of polyads from several in- dividuals were used whenever possible. For the self-pollinated inflorescences, the pollen donor was taken from the same inflorescence or from other inflorescences in the same individual; therefore, a great number of these flowers were geitonoga- mously pollinated. Treated inflorescences were marked with hanging labels. As the greenhouse was insect-free, inflorescence manipulation was mini- mized by avoiding the need to bag inflorescences. Sample size varied from two to nine individuals per population. After each treatment, brushes and hands were sterilized with ethanol. Since pod abortion occurs in Zapoteca species at several stages of pod development, the resulting pods were counted Seed set was estimated calculating the average only if they matured fully. in every population by number of fully developed seeds in mature pods. FLOWERING PHENOLOGY Although it is difficult to characterize the phe- nological behavior of a given species throughout its range, I shall attempt to draw some generali- zations about the flowering patterns in Zapoteca. This discussion is based primarily on species re- stricted to Mexico and Central America. In wide- ranging species such as Z. tetragona, flowering times vary from one region to another. This species, which usually grows in secondary vegetation de- rived from lowland tropical wet forests, flowers mostly during the dry season; nevertheless, in the Mexican state of Morelos, where a more seasonal climate exists, the populations flower primarily dur- ing the rainy season. Zapotec a portoric ensis subsp. flavida, which grows in wet habitats, also flowers during the dry season. By contrast, the species growing in drier habitats (thorn forests, tropical deciduous forests, and tropical semideciduous for- ests) tend to flower predominantly during the sec- ond half of the rainy season (e.g., Z. formosa, Z. lambertiana, Z. media, Z. alinae). The species from drier areas have shorter, more synchronized flowering periods than species living in wetter hab- itats (e.g., Z. amazonica and Z. tetragona), which continue to produce flowers for longer periods. Finally, Z. portoricensis subsp. portoricensis, which generally grows in montane mesophyllous forests (terminology following Rzedowski, 1978), also flow- ers in the wet season.

Anthesis and the process of flower presenta- tion. Field and greenhouse observations have shown that species of Zapoteca display predictable flowering mechanisms. All members of the genus exhibit nocturnal anthesis and a remarkable syn- chrony in floral behavior during flower presenta- tion. Usually the filaments of all the flowers in a head become erect in a springlike fashion late in the evening (ca. 17:00-18:00 hours), during the last two hours of daylight. Subsequently, when the 19:00 At about the same filaments are completely erect (ca. 18:00 hours), the anthers dehisce. time, nectar secretion begins, accompanied by pro- duction of a sweet aroma.

With few exceptions, the color of the staminal filaments Attractants: filament color and aroma. is constant in a given species of Zapoteca and thus is of taxonomic value. The filaments may be white (e.g., Z. alinae, Z. portoricensis, Z. tetragona), red-purple (Z. lambertiana), or a combination of white in the basal half and pink or red-purple in the distal half (e.g., Z. amazonica, Z. caracasana, Z. media). The widespread Z. formosa shows some geographical variation in filament color, and the recognition of subspecies within this species is based in part on this feature. This character is nearly always stable at the population level in Z. formosa; however, in a population observed in eastern Oa- xaca a mixture of plants with white (11. Hernández & Torres 216) and white pink filaments (/7. Her- nández & Torres 217) turned up. Similarly, in- dividual plants of Z. tehuana with either white or white/pink filaments were observed in a house population (/7. Hernández 950). The flowers green- of all species of Zapoteca produce a delicate, sweet fragrance, which presumably functions as does the color of the stamens in attracting pollinators (Brantjes, 1978 Rewards: nectar production. The amount of nectar produced by individual flowers varies among the species of Zapoteca, perhaps as a function of the size of the nectaries and the physical capacity all the tetragona produce As shown in Table 6, Z: quantities of nectar below or slightly above one of the staminal tube. species analyzed except microliter (ul) per flower. In the two populations of Z. tetragona (the species with essentially the most massive flowers in the genus), the nectar volumes were substantially higher (Table 6). The nectar of Zapoteca species has rather low sugar concentrations, ranging from 13.9 to 20.3%. The nectar volumes and sugar concentrations in the flowers of Zapoteca species reported here agree with those reported by Opler (1983) and Baker & Baker (1983) for settling moth-pollinated flowers. FLOWER VISITORS Inflorescences Zapoteca species are well adapted for pollination by moths. Field observations conducted in ten different populations representing five species of Zapoteca clearly showed that the flowers are consistently visited and pollinated by a variety of settling moths, mostly of families Noc- The moths were usually observed to visit the inflores- tuidae, Pyralidae, and Geometridae (Table 7). cences after some nectar had accumulated in the staminal tube and after floral fragance was detected by observers. Moths usually landed in the upper part of the inflorescence, where the underside of their bodies contacted the anthers and the stigmatic surfaces (Fig. 27). Moths generally moved from one part of the inflorescence to another in search of nectar, and the length of time they remained on an inflorescence was often up to 20-30 minutes. Aside from the species in Table 7, a substantial Volume 76, Number 3 Hernández Zapoteca number of species of smaller moths were excluded because they were considered to be ineffective pol- linators. Many species of moths were observed to exploit the nectar of Z. tetragona (population J) illegiti- mately. They extracted nectar by standing on the peduncles without touching the anthers and stig- mas. However, five species of moths were observed to visit the flowers of this species legitimately; among these, Palpita flegia (Fig. 27) and Diaphania jairusalis may be considered the primary polli- nators on the basis of their abundance (Table 7). The color of the wings of these two species is strikingly similar to that of the white filaments of Z. tetragona. In contrast, the nectar robbers, along with the few other occasional pollinators, have wings with a variety of color patterns. Although inflorescences of Zapoteca species dis- play the typical syndrome of characteristics asso- ciated with hawkmoth pollination (Faegri & van der Pijl, 1979), hawkmoths were rarely observed as visitors. During the course of my observations, only two hawkmoths were observed, one visiting the flowers of Z. formosa (population C) and one on Z. lambertiana (population J). A possible ex- planation for this is that the individual flowers pro- duce rather small amounts of nectar, making the visits energetically unprofitable to hawkmoths. Ac- cording to Opler (1983) and Haber & Frankie (in hawkmoth-pollinated flowers usually pro- duce much greater amounts of nectar (maximum available nectar = 130.5 ul; 1983) compared with the relatively smaller amounts found press), Opler, 1 in the flowers of Zapoteca (Table 6). Two unidentified species of crab spiders (Ara- neida: Thomisidae) were observed preying on moths visiting the inflorescences of Z. formosa subsp. rosei and Z. portoricensis subsp. portoricensts. These light-colored spiders would be inconspicuous on the inflorescences of Zapoteca species, where their cryptic coloration permits them to prey on flower visitors. Given that the spiders occurred in very low numbers, their negative impact on the reproductive potential of the plants is probably Such an association between crab spiders and. flowers has been reported by other authors (Wickler, 1968; Kevan, 1972; Gertsch, 1979, and others). unimportant. POLLINATION RELATIONSHIPS MI species of Zapoteca have very delicate, cup- shaped stigmas, and as indicated. elsewhere (Her- nández, 1986a), the concave area of receptivity is so narrow that only a single 16-grained polyad can FIGURE 27. Palpita, flegia visiting the flowers of e in a e near Catemaco, Ver: “XU, MO) H. He rnåndez 7 . MI poteca tetragona pæn, cruz be held (see fig. 11 in Hernández, 1986a). Con- sidering that the likelihood of a pollen unit reaching the stigma is directly proportional to the receptive (Cruden & Miller- Ward, 1981), one might anticipate that the chances of suecessful area of the stigma pollination in species of Zapoteca are rather low. As pointed out earlier, however, the settling moths that were recorded visiting species of Zapoteca normally remain on the inflorescences for consid- erable periods of time. The chances of successful pollination are also affected by the time the body of a particular pollinator makes contact with the stigma; therefore, the relatively long visits by set- tling moths compared with hawkmoths might be understood as a compensating factor to the intrinsic reaching the stigma in low chances of a polyac Zapoteca. The average number o ovules ovary in per Zapoteca species is highly correlated with the num- ber of pollen grains in the polyads. As indicated in Table 8, 15 and never exceeds tl polyad (16). polyad to the number of ovules is close to one, the number of ovules ranges from 11 to ie number of grains in the ratio of grains Therefore. the per Annals of the Missouri Botanical Garden TABLE 7. numbers of individuals collected from inflore »scences.

An almost identical situation has been re- ported by Kenrick & Knox (1982) and Knox & Kenrick (1983) for species of Acacia. In this ge- nus, however, the range of variation in the ratio of number of grains to number of ovules is some- what broader than in Zapoteca, but the species of Acacia with 16-grained polyads also have ratios approaching one (Kenrick & Knox, 1982).

In species of Zapoteca, sex expression and genetic self-incompatibility systems are the primary components of the breeding system that affect pollination and fertilization. Analysis of the inflorescences of several species has shown that morphologically expressed andromonoecy resulting from abortion of the gynoecium is widespread in the genus (Table 9). Functionally male flowers with an aborted gynoecium are irregularly distributed among populations. Generally, individual plants have inflorescences with varying proportions of her- maphroditic and functionally male flowers; how- ever, individuals with inflorescences composed en- tirely of hermpahroditic flowers are not uncommon.

The ratios of hermaphroditic to female-sterile flowers varied from 0.4 to 77.5 in the studied populations.

Nevertheless, a planned, detailed analysis of temporal variation in the ratios of her- maphroditic to female-sterile flowers in natural pop- ulations would probably contribute significantly to understanding this reproductive phenomenon. Incompatibility systems. The results of the incompatibility experiments show that of the five species studied, only Z. tetragona is clearly ge- netically self-incompatible, as indicated by the in- ability of the flowers to set pod following the self- and open-pollinated treatments in the two popu- lations (Table 10). In contrast, plants of the two populations of Z. formosa that were studied proved to be genetically self-compatible, and those from one additional population (H. Hernández 959) were f relatively high proportion of the untreated inflo- partially autogamous, judging from the fact that a rescences (20%) set pods (Table 10). Incompatibility studies on the remaining species (Z. media, Z. alinae, Z. portoricensis) were in- conclusive but suggested that these species are genetically self-compatible, at least in part. In both Z. media and Z. alinae, pod set was significantly higher in untreated (open) inflorescences compared Table 10). although this may have been partly the result of with the self-pollinated inflorescences — mechanical damage to floral parts during the hand pollinations.

Pre- suming that there was no accidental transfer of polyads among the untreated plants, the individuals of all three species tested were at least in part genetically self-compatible. CONCLUDING REMARKS Zapoteca species, are relatively consistent in several important features of reproductive biology. All the observed species exhibit nocturnal anthesis. The small flowers are organized in compact, cap- itate inflorescences, and there is remarkable syn- chrony among the flowers of a given capitulum in all the stages of flower presentation and in the patterns of aroma and nectar production. This sug- gests that ecologically the spherical capitula act as units of attraction. The particular combination of morphological and behavioral features in the inflo- rescences of species of Zapoteca is well adapted for pollination by settling moths. Moreover, the remarkable morphological correlation between the stigmas and the polyads in Zapoteca, along with the specific behavior of its pollinators, reflects a highly organized reproductive system. Reduction in the number of ovules in each ovary increases the reproductive efficiency of these species, giving a single polyad the potential of fertilizing all the ovules in an ovary. In other words, the high cor- relation between the number of ovules in an ovary and the number of pollen grains in a polyad is a reflection of the high probability of the ovules being fertilized by the pollen grains contained in a single polya According to Arroyo (1981), about half of the genera of Mimosoideae are andromonoecious; this condition occurs especially in taxa with capitate inflorescences. The results presented in Table 9 indicate that andromonoecy is widespread in Za- poteca, and the presence of a vestigial gynoecium in functionally male flowers strongly suggests that andromonoecy is derived from hermaphroditism in Volume 76, Number 3 Hernández 805 1989 this genus.

Her- nández 600), it was estimated rn each capitulum .3; N = 425) mature pods. comparative ly D in relation to the produced an average of 2.04 average number of hermaphroditic flowers per head (17.8 + 2.7; 100) in the same population. Thus, most of the flowers produced in Zapoteca serve only as attractive elements in the inflores- cence and as pollen donors (Stephenson, 1981, and references therein) Rather than being limited by pollinator activity, the probably affected by energetic, inflorescences of the Zapoteca species are and certainly by physical architectural constraints, which set the upper limit for maximum pod production. In this connection, Stephenson (1981) reviewed the avail- able evidence and suggested that “an upper limit to the number of pods that set is usually determined by resources rather than the number of morpho- logically female flowers, and . . . natural levels of pollination exceed pod set in many species." In this context, the adaptive nature of female sterility can be understood: given the lower pod set in Zapoteca populations, a reduction in the number of functional gvnoecia in an inflorescence would not reduce pod set. Vestigial gynoecia must be energetically less expensive to produce than the arger, functional ones. Thus, andromonoecy should be understood as a system that makes more efficient use of reproductive energy without compromising pollinator attraction (Ruiz & Arroyo, 1978; Pri mack & Lloyd, 1980; Arroyo, 1981; Bertin, 1982 and as a means to increase the pollen ovule/ ratios — and, consequently, the chances of pollination. CY TOGENETICS According to Goldblatt (1981), the genera of the Ingeae consistently have basic chromosome ential patterns in chromosome numbers and in mor- phological characteristics provided the justification for the segregation of Zapoteca from Calliandra sensu Bentham. METHODS Somatic chromosome counts were obtained from actively growing root tips taken from germinating seeds or mature plants in the Experimental Green- house at the Missouri Botanical Garden. The meth- ods employed were those of Goldblatt & Gentry 979). Root tips were pretreated in 0.003 M hydroxyquinoline for about seven hours at refrig- erator temperatures, 2:1] ethanol: glacial acetic acid for one minute. The — jæi then fixed ı absolute roots were hydrolyzed in 10% HCI for six minutes, then squashed and heated in formic-lacto-propionic orcein. RESULTS Chromosome numbers in Zapoteca were re- ported in Hernández (1986a). Counts for two ad- All ey- of Zapoteca have ditional taxa are included here (Table 11). tologically investigated species = 13 (Figs. 28, 29), which is basic numbers reported for the remaining genera of Ingeae (Goldblatt, 1981). Chromosome numbers consistent with the are now known for seven of the 17 species rec- ognized in this monograph, all of which are mem- bers of subg. Zapoteca. The species of the re- maining subgenera remain unknown cytologically. SYSTEMATIC. TREATMENT TAXONOMIC HISTORY OF ZAPOTEC AL Analysis of several critical characters of the neotropical species of Calliandra, a large genus currently undergoing revision (Forero, 1984; Her- nández, 1984), showed that Calliandra sensu Ben- tham apparently is polyphyletic. Consequently, the species of Bentham’s Calliandra ser. Laetevi- rentes were recognized as generically distinct (Her- nández, 1986a). For this natural group | proposed the name Zapoteca. Mimosa portoricensis Jacq. (— Zapoteca por- toricensis) and M. caracasana Jacq. (= Z. caraca- sana) were the first species to be published of what is now Zapoteca. They were described in 1791 on the basis of material collected by the Austrian bo- Annals of the 806 Missouri Botanical Garden TABLE 11. Chromosome numbers in Zapoteca.

This a plastic. species is wide- spread in dry and semiarid regions of central and northern Mexico. It can be readily distinguished from its close relative Z. alinae primarily by having larger, white/ purple-red filaments, usually shorter stature, and copious branching. In addition, the leaflets of Z. media are usually broader than those of Z. species is discussed further under Z. alinae. As shown in Figure 32, alinae. The relationship between these two most of the known populations consist of plants with leaves glabrous or ciliate and very sparsely pilose on the rachis and rachilla. Plants with pubescent or pilose leaflets have been collected primarily in restricted areas in the southern part of its range (Oaxaca, Puebla, San Luis Potosi, and Ta- Hidalgo, maulipas). Most of the collections with hairy leaflets Guanajuato, are concentrated west of Hidalgo (Fig. 32), where With the exception of a population from the Barranca de Tolimán, Mpio. Galeotti collected the type. Zimapán, Hidalgo. where plants with hairy and . with glabrous leaflets have been collected (41. Her- nández & Torres 15%, Moore 1383), populations of plants with hairy leaflets seem to be geograph- ically segregated from the glabrous ones. The distributions of Z. media and Z. formosa approach one another closely in some areas of northern Oaxaca and southern Puebla, but indi- viduals from these species are not known to grow together. There is evidence of hybridization, which results in morphological intergradation between the two. Plants collected in the area of Acatlán de Osorio and Tehuitzingo, Puebla (11. Hernandez & Torres 192, 2921, 294 9801). and Cuicatlán and Nochixtlán. (Conzatti 1929, 1747 hairy leaflets, fewer pairs of leaflets per Miranda 8. Sousa et al.

This endemic species, which is relatively con- sistent morphologically, is closely allied to Z. media by its l- to 3-jugate pinnae, small, numerous leaf- lets, and habitat preferences. It can be readily distinguished from that species by the usually more slender stems, branchlets, and peduncles, narrower and consistently glabrous leaflets, and primarily by its flowers with shorter, white filaments. Zapoteca alinae is allopatric with Z. media. Its distribution overlaps at the east of its range (H. Hernández & Torres 942) near Totolapan, Dist. Tlacolula, with that of Z. formosa subsp. rosei (H.

Zapoteca pri- marily by its much thinner pods with undulate surfaces and thinner margins, and specifically from Z. portoricensis by its red-purple filaments. Extra- floral nectaries between the pinnae in a single spec- imen (Dressler 2006, GH) and presumed similar- ities in the texture of the pods suggest a bu close relationship between this species and Z. lipes. Leaf indument is very variable in Z. "a bertiana: it varies at both intra- and interpopu- lation levels and does not seem to follow a geographical pattern. There is no morphological differentiation among the disjunct populations that occur over the ex- tensive geographical range of Z. lambertiana. It is likely that such discontinuities are of recent origin. Perhaps they resulted from tropical dry 818 Annals of the Missouri Botanical Garden forest fragmentations that occurred in the tropics subsequent to the Pleistocene glaciation, after the present wetter conditions originated disjunctions in the formerly extensive and continuous areas cov- ered by tropical dry forests. 5.

MINAS — GOlÁS: Salgado, Zapoteca filipes is probably closely related to Z. lambertiana as judged by the vegetative char- acteristics of these species, especially by the com- mon possession of membranous pods. Extrafloral nectaries, universal in Z. filipes, are occasional in Z. lambertiana. Zapoteca filipes can be readily distinguished from the remaining species of subg. Zapoteca by the cylindrical glands on the petiole, rachis, and rachillae. Hern., 163. 1986. Collectanea 4: 6. Zapoteca e eru H. Ann. Missouri Bot.

Zapoteca portoricensis as circ umscribed here, consists of three rather variable subspecies: toricensis, pubicarpa, and flavida. Each has a few distinguishing, variable characters (Table 12), although they intergrade and overlap. Consequent- ly, these subspecies are defined on the basis of combinations of characters. Viewed in a local con- text, each subspecies might be accorded specific rank; however, a synthetic analysis of all available material reflects the absence of strong morpholog- ical discontinuities distinguishing them. The three subspecies of Z. portoricensis have distinct habitat preferences: subsp. portoricensis occurs primarily in relatively wet, mid- to high- altitude habitats; subsp. flavida is found wet, lowland areas: and subsp. pubicarpa occurs in dry, in the West Indies, subsp. portoricensts usually occurs in much drier, mid-altitude areas. However, low, sometimes coastal, habitats. ZAPOTEC A PORTORICENSIS la. ae scandent; leaflet 2-6 mm; rolla 3-4 mm long; mature m to 16.5 c n € farida lb.

Disjunctions occur in the Sierra de Tamaulipas, Tamaulipas; Temascal- tepec, State of México; and in Honduras, Nica- ragua, Costa Rica, lection from Nova Friburgo, Rio de Janeiro, Brazil and Panamá. There is a col- (Curran 655). which was probably obtained from cultivated plants. This subspecies has usually been collected in mountain areas of moderate to rela- tively high altitude (800-2,100 m), in plant com- munities such as oak, pine, pine-oak, temperate deciduous, wet montane cloud, and montane rain forests, especially in secondary habitats. Never- theless, in some areas such as the Huasteca in the states of Hidalgo and San Luis Potosi, Mexico, populations usually occur at lower elevations, reaching as low as 165 m. Similarly, plants from the West Indies usually inhabit low elevation areas, down to sea level, with a much drier climate. Common names.

(Calliandra) portoricensis, which is probably incorrect. The only material | have been able to relate to this name is a specimen at the Willdenow Herbarium (Cat. No. 19143), Bot. Berol. W.." as indicated by a handwritten note in the lower right which comes from "Hort. margin. The brief description provided in the orig- inal publication of this species is a replica of the specimen label, which probably was handwritten by Willdenow himself, judging by the style of hand- writing (Burdet, 19). This specimen consists of two leaves, with the pinnae widely separate from each other, and rather few pairs of leaflets per pinnae. Because of the lack of flowers or pods, it is not possible to relate this specimen to Z. por- toricensts. Zapoteca portoricensis subsp. portoricensis, as delimited here, is an extremely variable, broadly defined subspecies, the most variable within the species. It can be distinguished from closely related subsp. pubicarpa by its glabrous pods, usually smaller flowers, glabrous to ciliate calyx teeth, and 12). It differs from subsp. flavida by its erect habit, usually smaller usually longer peduncles (Table and more numerous leaflets, usually larger flower parts, and smaller pods (Table 12). Perhaps the most highly variable character 1 subsp. portoricensis is the degree of pubescence of its vegetative structures. Plants range from en- tirely glabrous or glabrate to having branchlets and leaf parts densely villous with long tawny hairs. This tvpe of variation occurs at both inter- and intrapopulational levels, and, consequently, is of little taxonomic value. There are geographical pat- terns in the expression of this character. One ex- treme occurs in Veracruz, and to a lesser extent in Hidalgo and Chiapas, where there is a prevalence of collections with densely villous branchlets and leaves. The other extreme occurs in San Luis Po- tosi, Tamaulipas, and Central America, where gla- brous or sparsely villous leaves and stems predom- inate. In the West Indian plants, the leaflets are consistently. glabrous, but the branchlets may be villous or glabrous. Other variable characters in Z. portoricensis subsp. portoricensis are the size and number of pairs of leaflets per pinna. Most plants from the Sierra Mixteca, Sierra Madre del Sur, and Sierra Madre de Chiapas, in the states of Oaxaca and Chiapas, Mexico, are characterized by pinnae with smaller, more numerous (to 67) pairs of leaflets usually densely distributed along the rachilla, giving the pinnae a feathery aspect. Plants with small, numerous pairs of leaflets per pinna are also found in Central America. In Oaxaca, plants with leaves 824 Annals of the Missouri Botanical Garden of this sort also tend to have larger flowers and usually larger stipules. However, these characters have been found in numerous collections from dif- ferent regions (e.g.. Veracruz, Puebla, Hidalgo), where they occur in plants that do not have feath- ery leaves like the ones in Oaxaca, so that there is no definite geographical pattern and no basis for recognizing additional infraspecific taxa. In con- trast, many of the plants from the West Indies have larger and less numerous leaflets, thereby resembling subsp. flavida. e vast majority of collections of Z. portori- censis subsp. portoricensis have terete branchlets; however, plants with four-angled branchlets, a characteristic diagnostic for Z. tetragona, are not uncommon in some regions. Some of these plants may be the result of hybridization between subsp. portoricensis and Z. tetragona. These two taxa are generally ecologically isolated in Central Amer- ica and southern Mexico, where their geographical ranges overlap. In these regions, populations of subsp. portoricensis are found primarily in mon- tane cloud forest or similar habitats, whereas those of Z. tetragona occur in warmer lowland habitats. Populations with four-angled branchlets are most frequent in Guatemala, where these two taxa come into close proximity and in some cases are probably strict sympatric. A number of Guatemalan collec- tions of subsp. portoricensis have four-angled branchlets, although sometimes this characteristic is expressed only distally, or is less marked than in typical. Z. tetragona (e.g., Molina & Molina 12287, Standley 86574, 87132, Steyermark 34256, Williams et al. 12100, and others). Sig- nificantly, these plants are derived from areas where Z. portoricensis subsp. portoricensis and Z. tetra- gona approach each other, as for example, in the areas of San Juan Chamelco-Cobán-San Pedro Corchá, Departamento de Alta Verapaz; Colomba Santa Maria de Jesús, Departamento de lenango; Ipala-Comatán, Departamento de Chi- quimula; and Escuintla-San Vicente Pacayas, Departamento de Escuintla. Individuals with four- iden branchlets also occur in some other regions (e.g.. Orizaba-Cordoba, Veracruz, Chiapas), and even in areas where Z. tetragona does not occur, such as Haiti. West Indian populations often differ from those on the mainland in some characters, possibly the result of the smaller gene pools in insular popu- lations and the selective effects of local climates. In many of the plants collected in the West Indies, the leaflets are comparatively larger, approximat- ing those of Z. portoricensis subsp. flavida. Ja- maican specimens are characterized by smaller (4.5-6 cm long) pods and by usually smaller, black seeds with regular pleurograms, as compared with the mainland populations. In addition, some of the plants from this island have | -2-jugate pinnae with fewer pairs of leaflets. Zapoteca portoricensis subsp. portoricensts and its close relative Z. caracasana subsp. caracasana co-occur on Hispaniola, although it is unclear whether they really grow together. Here, as else- where in the West Indies, most plants of subsp. portoricensis differ from mainland populations in having calyces with the teeth lanceolate to linear lanceolate, a characteristic of Z. caracasana. In some cases, the identification of herbarium speci- mens is troublesome if information concerning habit and filament color is not provided. However, there are several diagnostic characters for each taxon (Table 13, while comparing the two species, applies to the two subspecies discussed here). Zapoteca caracasana subsp. caracasana differs from Z. portoricen SIS subsp. portoricen sis in its prostrate/ scandent habit, smaller flowers, white /red-purple filaments, and by the frequent occurrence of pseu- dopaniculate inflorescences with more slender pe- duncles. The relationships between these two taxa are discussed further under Z. caracasana. 6b. Zapoteca portoricensis subsp. pubicarpa . Hern., TYPE: Mexico. Oaxaca: Dist.

Caltepec, Rincón Fn y Hierl rba, p al W de Caltepec, Tenorio & Romero 7604 y XU Zapoteca portoricensis subsp. pubicarpa is closely related to subsp. portoricensis, from which it can be distinguished primarily by having puber- ulent pods, villous calyx teeth, larger flowers, and usually shorter peduncles (see Table 12). The ova- ries are glabrous, but pubescence becomes evident soon after the pods start to develop. The charac- teristics used to define this subspecies are not dis- continuous with those of subsp. portoricensis. However, the particular combination of morpho- logical characters defining subsp. pubicarpa is dis- tinctive and appears to be relatively constant throughout its range. This and its. biogeographic consistency justify its recognition as a separate subspecies. The pubescence of the pods is the main diag- nostic character for this subspecies. Nevertheless, hairy pods have been found in two collections of Z. portoricensis subsp. portoricensis from Nica- ragua (Laguna 333, Moreno 8272). These plants, however, have smaller flowers and longer peduncles than are characteristic of subsp. pubicarpa:; they clearly fall within the limits of subsp. portoricensis. Flower size is variable in subsp. portoricensis, with large (calyx ^ 2-3 mm long. corolla — 6-8 mm long) flowers found in plants throughout the range of this subspecies: such flowers, however, are rarely as large as those of Z. portoricensis subsp. pubi- carpa, and the plants on which they occur never have the hairy pods or short peduncles character- istic of subsp. pubicarpa. 6c.

In addition, subsp. flavida primarily grows in habitats associated with lowland tropical forests, whereas the two other subspecies have been collected chiefly in subtropical, mid- to relatively high-altitude habitats. Zapoteca porto- ricensis subsp. flavida can be distinguished from ^. caracasana by having larger leaflets, flower buds constantly glabrous, deltate-triangular calyx teeth, white filaments, and larger pods. The capit- ula are arranged in pseudopanicles only occasion- ally in Z. portoricensis subsp. flavida; this is a very common condition in Z. caracasana. Zapoteca portoricensis subsp. flavida is rela- tively constant morphologically throughout its wide range; however, a number of collections from South America have a combination of characters that differ from those of the Mexican and Central Amer- ican plants. Characteristics of a collection from Colombia (Philipson et al. 1418) suggest mor- phological intergradation between Z. portoricensis subsp. flavida and Z. caracasana: narrowly tri- angular to linear-triangular stipules, leaflets 8 X 2 mm, numerous (to 36) pairs of leaflets per pinna, capitula arranged in elongate pseudopanicles, calyx with linear-lanceolate teeth, and white filaments. An almost identical situation is displayed by most of the Brazilian collections of Z. portoricensis subsp. flavida (Andrade-Lima 70-5777, Ducke 1517, 16051, Fróes 30295, Guedes 378, Hatschbach 34270, Pickel 2430, Tavares 754). Here, several of the vegetative and reproductive characters di- agnostic of either Z. portoricensis subsp. flavida or Z. caracasana intergrade in particular popu- ations. Although it is not known whether Z. portori- censis subsp. flavida and Z. caracasana ever ac- tually grow together in specific habitats, they have been collected in comparable microhabitats (e.g., river banks, shady sites, and thickets), which raises the possibility of hybridization. Populations of Z. caracasana, however, occur more commonly in drier habitats than do those of Z. portoricensis subsp. flavida. The distributions of these two taxa overlap only in the area of the Andes, where there is much local microhabitat differentiation. Collections from Bolivia have some characters that do not correspond with those commonly found in individuals of Z. portoricensis subsp. flavida. For instance, the filaments are reported to be white- pink, instead of white, in Steinbach 822. The calyx in almost all the Bolivian collections has lanceolate teeth (Steinbach 5412, Weddell 4237, Williams 207). In addition, the mature pods are always smaller than typical for this entity (to 10 cm long) Volume 76, Number 3 1989 Hernández Zapoteca FIGURE 37. and the valves are thicker (e.g., Pierce s.n., Troll 1738, Williams 244). 7.

Further, the filaments are white in Z. portoricensis subsp. flavida, but white in the basal half and ochroleucous in the distal half in Z. mollis (Grayum 1162, 4290). (It would be desirable to check more living individuals for this feature.) Contrasted with Z. portoricensis subsp. flavida, which is commonly found in thickets in wet lowland habitats (e.g., along ater courses and near ponds), populations of Z. mollis usually occur in relatively dry habitats. With the exceptions of Z. formosa subsp. salvadorensis, Z. caracasana subsp. weberbaueri, and Z. por- toricensis subsp. pubicarpa, this is the only species in the genus with hairy pods. In addition to the few collections of this species from Costa Rica, there is a collection from Santa Cruz, near Panama City (Arroyo 37), which in- dicates a disjunction in its range. This collection, with immature pods, matches the plants collected in Costa Rica well. Recent attempts (1984) to re- collect from this population have been unsuccess- ful, presumably due to widespread destruction of natural habitats in this part of Panama. 8.

Zapoteca caracasana is closely related to Z. portoricensis, and these two species have been merged at times. For instance, Bentham (1844 considered Z. (Calliandra) caracasana as a syn- — onym of C. portoricensis, although subsequently, 1875), he recognized them as distinct species. Later, Woodson & Schery (1950) treated Calliandra portoricensis as a synonym of C. caracasana.

Observations on cultivated ma- terial and information from herbarium specimens suggest that the scandent/prostrate habit of Z.

Within Z. portoricensis, the scandent habit occurs only in subsp. /lavida. There are, however, important differences in growth habit be- tween that entity and Z. caracasana: cultivated specimens of of Z. caracasana (H. Hernández 961) had extremely short primary stems, usually ds rise to drooping, very elongate branchlets 10 cm above the soil level, while those of Z. Mises subsp. flavida develop very long, flexible primary stems, sometimes reaching several meters before giving rise to secondary branches. The flowers of Z. caracasana are generally smaller than those of Z. portoricensis, and the calyces are consistently deeply divided to the base, with the teeth lanceolate to linear-lanceolate. In addition, the two species are easily distinguished by their filament colors (Table 13) and by the usually smaller pods in Z. caracasana. Pod size, however, is highly variable in Z. portoricensis. Although the degree of pubescence of stems and leaves is extremely variable in Z. caracasana and in Z. portoricensis, the branchlets of the former Volume 76, Number 3 Hernández 831 1989 Zapoteca TABLE 13.

However, the peculiar vestiture observed in the flower buds of this species has never been observed in Z. portoricensis. Fur- ther discussion of the relationships between these two species is under Z. portoriensis. Zapoteca caracasana consists of two closely related subspecies: caracasana (with glabrous pods) and weberbaueri (with canescent or pubescent pods). As in the other taxa of Zapoteca with pu- bescent pods (Z. mollis. Z. portoricensis subsp. pubicarpa, Z. formosa subsp. salvadorensis), the ovaries of Z. caracasana subsp. weberbaueri are glabrous, and the hairs of the pods presumably develop after fertilization. However, the ovaries in this subspecies occasionally have a few hairs. KEY TO THE SUBSPECIES OF ZAPOTECA CARACAS ANA la. Pods glabrous or nearly so "EE oo. Ba. subsp. caracasana lb.

Zapoteca tetragona is closely allied to Z. por- toricensis but can be readily distinguished pri- marily by having conspicuously tetragonal branch- lets, larger corollas, and longer filaments. Despite the opinion of Woodson & Schery (1950), who suggested that Z. tetragona (Calliandra tetra- gona) is distinguished “unnaturally” by its tetra- gonal branchlets, implying that it is not differen- they call the this entity is maintained tiated from what “caracasana portoricensis complex." here as a separate species. Discussion of the re- lationship between Z. tetragona and Z. portori- censis is provided under the latter species. Zapoteca tetragona is probably also related to can readily be distin- Z. andina, from which it guished by having adpressed, usually larger, tri- angular-linear to triangular-lanceolate stipules, de teeth, and totally white filaments. Discussion of the relationship between these two species is provided under Z. andina. 836 Annals of the Missouri Botanical Garden Acacia quadrang eularis Link (Enum. Hort. Be- rol.

Zapoteca andina resembles Z. tetragona in althoug branchlets are sometimes visibly four- miris only most of its vegetative features, the in the youngest parts. It differs from Z. tetragona primarily by having smaller, triangular, descending or depressed, auriculate stipules and by having narrowly oblong calyx teeth, smaller floral dimen- sions, and white/red-purple filaments.

Chihuahua, and Sinaloa, south and southeast through Central America to central Costa Rica. In South America it occurs in northern Ven- ezuela and northern Colombia, and also in Brazil (Minas Gerais), Bolivia, Paraguay, and northern Argentina. It has been collected on Cuba, Trinidad, This subspecies has not been collected in Panama, most and other smaller islands in the West Indies. of Colombia, Ecuador, or Peru. It is relatively common in open sites in seasonal, dry environments such as tropical dry forests, coastal thickets, and arid thorn serub, although occasionally it is found in wetter disturbed or undisturbed habitats, in semi- evergreen or evergreen tropical or subtropical for- ests. It has also been collected occasionally in pine and pine-oak forests in Mexico. Collections come 2.000 m.

Fourteen names have been published that fall within the boundaries of this subspecies as | have defined it; most of them have been based primarily on regional variations in leaf- let morphology and vestiture. These characters, along with the size of the flower parts and pods, are highly variable at an inter- and intrapopulation level, especially in the Mexican and Central Amer- ican populations, and thus they are not useful tax- onomically. Perhaps the most variable character is leaflet size, but the variation does not correspond to a geographical pattern. Á similar situation occurs with variation in leaflet vestiture; plants with short- pubescent or villous leaflets occur in the same areas as plants with glabrous leaflets throughout most of the range. In addition there is continuous variation in leaflet apex morphology, ranging from rounded to acute. Plants from the southern limits of this subspecies are comparatively consistent. morpho- logically. In this area, they usually have medium to relatively small leaflets, and the number of pairs of leaflets per pinna is quite regular. The entity most closely related to Z. formosa subsp. formosa appears to be the Central American subsp. salvadorensis, which is distinguished by its densely pilose pods. Zapoteca formosa subsp. for- mosa is consistent in having glabrous pods, al- though in El Salvador and Venezuela, plants with glabrate pods have been collected. In a few col- lections of subsp. formosa from Oaxaca, Jalisco, Honduras, Venezuela, and Cuba, the pods are pi- lose or sparsely pilose when very young, but soon become glabrou Zapoteca Pm subsp. formosa also appears closely allied to subsp. rosei, from which it differs by having white or white-green filaments (Table 4). Plants of subsp. formosa also usually have larger leaflets and are generally more robust than those of subsp. rosei. In a number of instances, however, the identification of these two subspecies is troublesome if flowers are not available or if filament color is not known. In some areas of the Mexican Pacific slope, especially in the state of Guerrero, where these two subspecies presumably occur sympatrically, hybridization probably takes place, resulting in morphological intergradation. In this area, many collections of subsp. rosei have larger leaflets than normal in this entity, thus re- sembling those of subsp. formosa. Such areas of intergradation are in Tecpan de Galeana (e.g., Hin- ton 14335, 10894, Ladd et al. 206) and Zihuata- 398, Ladd et al. 216, Sousa 6159). Similarly, in some localities of the nejo (e.g., Tenorio et al. District of Yautepec in Oaxaca, plants from the two subspecies have been found growing together 215, 217; Telles 13). The collections belonging — e.g., H. eie & Torres Magallanes 111, either to Z. formosa subsp. formosa or to subsp. rosei, but of ambiguous identity, are listed sepa- rately under Z. formosa subsp. formosa. Zapoteca formosa subsp. formosa is distinguish- able from the West Indian subsp. gracilis by hav- ing oblong-obovate leaflets, usually larger, lanceo- late to ovate-lanceolate stipules, and glabrous, pubescent, or villous leaflets, which contrast with the consistently glabrous ones of subsp. gracilis. Subspecies formosa differs from subsp. mollicula and subsp. schottii by its more robust habit, white filaments, and larger Pers leaflets, stipules, flower Table 1 ere is a wide rude tion in the South Amer- ican distribution of Z. formosa subsp. formosa, — parts, and pods from northern Colombia and Venezuela to Bolivia, southeastern Brazil and Paraguay (Fig. 44). Mor- phologically, the populations from the southern region clearly belong to the subspecies. Perhaps this geographical fragmentation is related to the current scarcity of relatively dry, seasonal, lowland habitats in the intervening region. As reviewed by Haffer (1982, fluctuations during the Pleistocene had a great and references therein), climatic Volume 76, Number 3 1989 Hernández effect in tropical areas. In lowland areas of the Neotropics, alternating periods of cooler and drier climates probably caused extinction or displace- ment of species adapted to the warm-wet forest conditions during the interglacial periods, and only a few areas (forest refugia) remain relatively un- changed. Consequently, great expanses of wet for- ests were replaced by drier, more open vegetation in the Amazon Basin (Ab? 1982; Absy, 1982; Bigarella & Andrade-Lima, 1982; van der Ham- men. 19 1982; and others). In light of this body of ideas, it can be postulated that the populations of Z. formosa subsp. formosa found a more suitable environment during the dry phases of the and then were continuously distributed across the Amazon Basin; and that the America is the Saber, Prance, Pleistocene, present-day disjunction in South result of fragmentation of a formerly more contin- uous range after the warm, wet present-day con- ditions were established. 12b.

FLORIDA: Miami, Fairchild Tropical Garden, Gillis 8672 (MO) Zapoteca formosa subsp. gracilis is relatively uniform morphologically compared with the other subspecies of Z. formosa. It is related to subsp. formosa, from which it is distinguished by having elliptic to elliptic-oblong leaflets and narrowly tri- angular stipules and by being glabrous (Table 14). The seeds of subsp. gracilis differ from those of the remaining subspecies of Z. formosa by having semiregular, instead of irregular, pleurograms. Subspecies gracilis and subsp. formosa are essen- tially allopatric, although there are a few collections Cuba. Their rela- of both from Oriente Province, tionship is discussed further under Z. formosa subsp. formosa. Although leaflet morphology is quite constant among populations of Z. formosa "E gracilis, a few plants from the Bahamas (e.g., Correll & Correll 45614, Curtis 82, Gillis 11 oe Hill 3003) have unusually narrow leaflets. These plants could be confused with Z. portoricensis but can be readi- ly distinguished by their smaller and narrower stip- ules and relatively thicker leaflets (also see Table 14). In addition, Z. formosa and Z. portoricensis are strongly segregated geographically in the West — Indies. 12d. gins) H. Hern., Zapoteca formosa subsp. rosei (Wig- comb. nov.

It has also been collected in southern Baja California and on the Revillagigedo Islands (Isla Socorro and Isla Clarión). A number of col- lections have been made from the districts of Yau- tepec and Tlacolula. Oaxaca. and from a number of localities in the Balsas Basin. It is relatively common in disturbed or undisturbed habitats of tropical thorn woodlands and tropical deciduous or tropical semievergreen forests.

Leaflet size is highly variable within and between popula- tions, and a clinal variation pattern is evident, especially in the northern portion of its range, possibly a reflection of decreasing precipitation from south to north. There is some variation in filament color within Z. formosa subsp. rosei, although this character is consistent at the populational level. The distribution of the different color morphs is not known with precision. The following generali- zations can, however, be drawn: the most wide- spread pattern of filament color is the white/red- purple pattern, which occurs from southern Oaxaca to Sonora and Chihuahua. The populations from the Isthmus of Tehuantepec, at the eastern distri- butional limit (e.g.. Hernández & Ramírez 918, Sousa & Téllez 8687), and a few populations from Michoacán (e.g., H. Hernández & Chacón 185, Soto 1636) ments. Populations from the districts of Tlacolula have entirely red-purple fila- and Yautepec, Oaxaca, have white pos filaments (e.g.. H. Hernández & Ramírez 930, 943). Zapoteca formosa subsp. rosei is closely related to subsp. formosa and to subsp. mollicula and subsp. schottii. It can be distinguished from subsp. color of its filaments and by its usually smaller leaflets. However, plants of these two subspecies sometimes resemble each other closely. In some localities of Guerrero, the two subspecies become sympatric and apparently in- tergrade morphologically. These collections are not assigned to a particular subspecies; they have been listed separately under subsp. formosa (and see discussion under this subspecies). will be discussed below under the respective subspecies, patterns of morphological variation, es- pecially in leaflet size, are essentially continuous between Z. formosa subsp. rosei on the one hand and subsp. mollicula and subsp. schottii on the other. Although each of these is relatively easily identifiable, their integrity breaks down because of the existence of morphological intermediates. Za- poteca formosa subsp. rosei can be distinguished from subsp. mollicula by having more-developed leaf parts (e.g., longer petioles and rachillae, usu- ally more numerous and larger leaflets, and usually larger stipules (Table can be distinguished from subsp. schottii primarily 14)). Similarly, subsp. rosei Volume 76, Number 3 89 Hernández Zapoteca by having more numerous and larger leaflets (Table 14). Nevertheless, the differences between these two subspecies are less marked than those sepa- rating subsp. rosei and subsp. mollicula. Geo- graphically, subsp. mollicula and subsp. schottii are peripheral to but contiguous with subsp. roset. This fact, along with their close morphological af- finities, suggests that subsp. mollicula and subsp. schottii were derived from subsp. roset. Further discussion of the presumed relationships of these three taxa is provided under the respective sub- species. 12e. Zapoteca formosa subsp. mollicula (M. Martens & Galeotti) H.

Zapoteca formosa subsp. mollicula represents an extreme of morphological variation within the species in petiole length, number of pairs of pinnae, and number and size of leaflets. It is distinguished from the other subspecies by its | pinnae with fewer and smaller leaflets and by its aflet size, however -, rarely 2-jugate somewhat shorter internodes. Lea is extremely variable in this sna o both at an intra- and interpopulational level (e.g., Cruz Cis- neros 2563, H. Hernández & Torres 216, Rose & Hough 4671, Sousa et al. 6901, 0905). Sim- ilarly, vestiture is highly variable, and does not display any coherent pattern. Zapoteca formosa subsp. mollicula clearly is closely related to the highly variable subsp. rosei. Perhaps the most taxonomically meaningful char- acters separating these taxa are the usually more reduced leaves of subsp. mollicula. However, vari- ation in leaf characters (e.g., petiole length, number of pinnae, number of leaflets, size of leaflets) is essentially continuous, especially when plants of from the districts of Tlacolula and , Delgado et al. 724, H. 919 915, 2 dig = subsp. rosei Yautepec, Oaxaca (e.g Hernández & Torres 207 , 210, Hernández & Ramírez 930, 932, 913, Magalla- nes et al. 199, Sousa et al. 0519) are compared Annals of the Missouri Botanical Garden ND.

In the Baboquivari Mountains and in northern So- nora and Chihuahua, a number of difficultly placed intermediate specimens have been collected. Zapoteca formosa subsp. schottii could be con- fused with subsp. mollicula, since they have leaflets of comparable size. However, subsp. schottii can be readily distinguished by the longer internodes and more elongate petioles and rachillae (Table 4). Further, although vestiture is highly variable in subsp. mollicula, most of its individuals have denser vestiture than do plants of subsp. schottii. 13. Zapoteca scutellifera (Benth.) H.

More- over, it can be distinguished from Z. formosa subsp. formosa by its white/pink, rather than white, fil- aments. The scutelliform glands, which are con- stant throughout the known populations of Z. scu- tellifera, are an excellent diagnostic feature, as they occur only in this species of Zapoteca.

Zapoteca, and further knowledge on this species could provide evidence for its placement in a sep- arate subgenus. It differs from the remaining species of subg. Zapoteca primarily by having conspicuous brochidodromous leaflet venation and relatively thick leaflets. It might be confused with some of the species with oblong or ovate-lanceolate leaflets of comparable size (e.g.. Z. portoricensis and Z. lambertiana) but differs by having leaves usually having fewer pairs of pinnae, smaller stipules, white or white/pink filaments, and shorter stature. The relationship between Z. tehuana and Z. aculeata are discussed under the latter. IH. Zapoteca subg. Aculeata H. Hern., subg. nov. TYPE: Zapoteca aculeata (Spruce ex nth.) H.

It is a poorly known, unmis- takable species characterized by spinescent sti- pules, medium size, and coriaceous, ovate-lanceolate leaflets, which are usually larger than the essen- tially membranous leaflets of subg. Zapoteca. It is not obviously closely related to any other species of the genus; however, as shown in the chapter on morphology, an analysis of its leaflet architecture revealed outstanding similarities to that of Z. huana. Zapoteca aculeata is known from only a few collections made in a restricted area of the Ecuadorian Andes and from cultivated individuals 856 Annals of the Missouri Botanical Garden FIGURE 46. — Zapoteca a C.

These genera are Aletris, Amianthium, Chamaelirium, Chionographis, He- Metanarthecium, Narthe- Pleea, Ste- Toxicoscor- lonias. Helontopsts. Nietneria, Oceanoros, Petrosavia, Schoenocaulon (= Sabadilla), Tofieldia, ) psilandra, Ae- cium, Protolirion, nanthella, Stenanthium, dion, Tracvanthus, Veratrum, rophyllum, and Zigadenus (Dahlgren & Clifford, 1982). Krause (1930) recognized the tribe To- fieldieae (Liliaceae- Melanthioideae), in which To- fieldia (Temperate-Arctic Northern Hemisphere), Pleea (eastern North America), Varthecium — and — n (Northern Hemisphere Vietneria (Guinea were included. However. in his treatment, Aletris was placed in the different subfamily, Alectroideae. Hutchinson (1934, 1959) grouped these genera into two tribes, Heloniadeae and Narthecieae. The Heloniadeae, characterized by the absence of bracts, consist of Helonias. Chamaelirium, Y psilandra, and Chionographis. and the tribe Narthecieae, characterized by the presence of bracts, comprise Pleea, Tofieldia, Xerophyllum, He- loniopsis. Clara, Metanarthecium, Hewardia, Varthecium, Aletris, and Vietneria. Hutchinson (1934, 1959) regarded the Heloniadeae as the most primitive tribe in the Liliaceae, and that the tribe is closely related to the Narthecieae. Dahlgren et al. (1985) placed these genera in the family Melanthiaceae Melan- Chionographi- and recognized six tribes, Petrosavieae, thieae, Narthecieae, Tofieldieae, deae, and Xerophylleae. in the tribe Narthecieae. Although many brief notes on pollen morphology of these genera using light microscopy have been given by Beug (1961). Erdtman (1952), Faegri et al. (1964), Huang (1970, 1972), Huynh (1976), (1956), Kuprianova (1948), Radurescu 1973), Schultze (1978), Shimakura (1973), Thanikaimoni (1970), Ting-Su (1949), Utech 979), Wunderlich (1936), and Van der Hammen (1956), a comprehensive pollen morphological study has not been made for these genera with electron They included Lophiola Ikuse Ss — ~ microscopy Although Schultze (1978) classified Chiono- graphis, ) psilan- dra, and Helonias in the the different pollen types and exine structure suggest that the treatment is inappropriate.

He also pointed out that palynological evidence on the related genera would be useful to reveal their systematic relationships. In the present study, pollen grains of 92 samples of 40 species of 15 genera in the Melanthiaceae were studied in detail with transmission and scan- ning electron microscopes. The probable system- atic relationships of these genera are proposed based on the palynological evidence thus obtained. MATERIALS AND METHODS Pollen grains were taken from specimens in the herbaria of Carnegie Museum of Natural History (CM), U.S. National Arboretum (NA), Kunming Institute of Botany (KUN), Kyoto University (KYO), and Tohoku University (TUS). Voucher specimens are listed in Table 1. Pollen grains from each specimen were observed using scanning elec- tron and transmission electron microscopy. Prep- aration methods followed Takahashi (1982b). An image analyzing system IBAS-1 was used for mea- surements and calculations of pollen grains.

DISCUSSION Helonias and Ypsilandra are characterized by a distinctive exine structure that consists of an Volume 76, Number 3 1989 Takahashi & Kawano Melanthiaceae Pollen — amorphous layer and spinules, and the same exine structures were observed in Heloniopsis (Vaka- hashi, 1982a). Utech (1978, 1980) and Utech & Kawano (1981) suggested that //eloniopsis and Helonias should be maintained in the same tribe based on floral vasculature and karyology despite Hutchinson's (1934, 1959) placement of /7elonias in Heloniadeae apart from Heloniopsis in the Nar- thecieae. The present pollen morphological evi- dence supports the suggestion by Utech & Kawano (1981) and further indicates that ) psilandra should be included in the same tribe with /7elonias and Heloniopsis. The three genera are closely related to each other and are distinctive because of the amorphous exine structure with spinules. Dahlgren et al. (1985) included /lelonias and Heloniopsis in the tribe Narthecieae, with Methanarthecium, Vietneria, Narthecium, and Lophiola. We now regard Helonias, Heloniopsis, and Y psilandra as congeneric, and a more thorough taxonomic ac- count of this controversial group is needed. Chionographis from Japan has clavate exine sculpture and four-porate pollen grains. Chamae- lirium from the eastern United States has the same pollen. This type of grain and exine structure are unique in the Melanthiaceae, and suggest that Cha- maelirium and Chionographis are closely related to each other as an isolated group in the Melan- thiaceae. The pollen morphology supports the treatment of Dahlgren et al. (1985), who distin- guished the tribe Chionographideae as made up of Chionographis and Chamaelirium. Japonolirion, which consists of only the Jap- anese endemic J. ozense, is sometimes included in Tofieldia (Willis, 1966; Hutchinson, 1934, 1959). The pollen grains of Japonolirion are monosulcate with gemmate exines, as opposed to those of 7o- fieldia, which are disulcate with reticulate exines. The pollen morphology of Japonolirion implies that the genus should not be e in Tofieldia but should be treated as a se e genus. The report of gemmate exine of Tofieldia puo (Ikuse, 1956) appears to be incorrect, as we have found reticulate exine in this species, conforming to other para species of Tofieldia. There is a wide range of variation in exine sculp- ture, perforate-foveolate, reticulate, and gemmate types in the genus dletris. The species with gem- mate exine are 4. lanuginosa and A. pauciflora, which are distributed in China and Nepal. The other species of Aletris have reticulate exines. Similar variation in exine sculpture occurs in Clintonia (Takahashi & Sohma, 1982) and Paris (Taka- hashi, 1984). A parallel derivation from tectate- perforate to intectate exine appears to have taken place independently within these genera (laka- hashi, 1984) Ambrose (1985) transferred the genus Lophiola into the Narthecieae. The exine sculpture of the genus has a reticulum similar to that of genera in the Narthecieae; thus the palynological evidence supports Ambrose's taxonomic position of Lophiola. | the evidence available at present suggests that Heloniadeae and Narthecieae sensu Hutchinson (1959) consist of at least three or four heterogenous groups, and therefore the revision of the classifi- catory system of these groups is now in order.

Jo The presence of petiolar nectaries and. purple flowers with a nonplicate operculum, suggests a relationship to P. lancifolia Desv., of subg. Chlo- ropathanthus (Harms, 1925; Killip, 1938), which is known only from Jamaica. Unlike that species and others of subg. Chloropathanthus, P. sierrae has well-developed petals, poorly developed lami- nar foliar nectaries, and seeds with transverse ru- gulose ridges. This unique combination of char- acters requires the creation of a new subgenus. Data from pollen studies (Prėsting, 1905; Spirlet, 1965; Escobar, unpubl.) suggest that several pur- ple- or red-flowered species (usually with a tubular hypanthium and therefore presumably humming- bird-pollinated) have arisen independently from the large and variable subg. Plectostemma. They do not suggest that all species with the hummingbird- pollinated syndrome are monophyletic. Passiflora solomonii L. Escobar, sp. nov. TYPE: Borivia. La Paz: Prov.

The unusual leaf shape of Passiflora solomonii is reminiscent of P. exoperculata of subg. Plec- tostemma but is transversely linear rather than transversely ovate; P. exoperculata also differs rom P. solomonii in possessing prominent petiolar nectaries and capitellate inner coronal filaments as well as longer peduncles and shorter leaf lobes.

In A. wurdackii, the leaf blade is often elliptic-ovate, about 1.9 times longer than wide with an angular basal sinus, and the spathe is decurrent for 3.5- 7.5 cm.

Inflo- rescence unknown. The type collection was taken from a plant grow- ing as an epiphyte 2 m above the ground; it is not certain that it represents the fully mature adult phase of this species. A similar though somewhat less adult plant, collected in the same area as the type, has recently been seen in cultivation at the family home of Lic. Germàn Carnevali in Maracay, Venezuela. A juvenile specimen, Bunting 2916 (MY), collected in the same sector at km 126 south of El Dorado, Bolivar, Venezuela, apparently per- tains to this taxon. It has leaves of similar form, texture, and color, but, as is typical of juvenile shoots, has a more slender stem with elongate in- ternodes and has wide-winged petioles basally en- circling the stem and sheathed up to the base of the blade. This species differs from Philodendron meli- nonii Brongn. ex Regel by the proportionally short- er petioles and narrower leaf blades. In P. meli- nonii, the blade length is 1.4 times longer than the petiole and 1.5- 2.4 times longer than wide. The specific epithet reflects the fact that the leaf blade is three times longer than the petiole and more than three times longer than wide. I am grateful to Lic. German Carnevali and his wife, Sra. Ivón Ramirez de Carnevali, for making available dried and living specimens of the aroids collected by them during recent botanical explo- rations.

HOSTA JONESII (LILIACEAE/FUNKIACEAE), A NEW SPECIES FROM KOREA Hosta Tratt. is an economically important genus of approximately 22-25 species restricted to east- ern Asia. Hosta has been placed in the Liliaceae 1981; 1964) or Funki- aceae (Dahlgren et al., 1985). Bailey (1930), Stearn (1931), and Hylander (1954) all pointed out that the major difficulty with the classification of the (Cronquist, Hutchinson, Hosta lies in the uncertainty regarding criteria for delimiting the species. The taxonomic difficulties have been attributed to relatively few diagnostic characters (Fujita, 1976), the extreme difference in appearance between living plants and dried her- barium specimens (Hylander, 1954), and possible widespread hybridization (Maekawa, 1940). Thus the treatment of species within Hosta has varied Maekawa 1969) described several new species but combined depending on authors. For example, others recognized in his 1940 treatment. Fujita (1976) noted that Maekawa (1940, 1969) did not consider the variability of natural populations when developing his classification. Fujita recognized only 15 species as native to Japan, while Maekawa (1969) had recognized 25 species there. Although Fujita carefully described morphological characters and ecological and geographical distribution, his studies were confined to Japan. In 1985, 1987, and 1988, trips to collect hostas from natural populations in | conducted field Korea and on Tsushima Island of Japan in order to understand better the variation patterns. While visiting several islands off the coast of southern Korea, | encountered a morphologically distinct group of Hosta DoD ie not referable to any described species of Hosta. The herbaria at Seoul National University (SNU), Tokyo University (TD, and Kyoto University (K YO) were visited and there were several undetermined specimens of this group collected by Young Chung (SNU) and one specimen collected by T. Nakai (TI). Loans were examined from BH, BM, E. K, L, specimens of the group were encountered. and PE, but no herbarium This series of populations is a new species as described below Hosta jonesii M.

Hosta jonesii is distinguished from other species of Hosta by the navicular, green, persistent bracts; thick, adaxially dark dull green leaves; and white- lined leaf margins. This species appears to be re- lated to H. minor (Baker) Nakai by the shape of bracts and perianths and by the creeping rhizomes. It differs by the terete scapes, elliptic-lanceolate eaf blades, and flowering period from middle Au- gust to early September. Hosta minor flowers in mid July to early August and is endemic to south- eastern Korea, including Wando and Kojae islands. The new taxon also is very close to /7. tsushimensis 1988) but differs by having short creeping rhizomes; longer perianth lobes; upper dilated portions of perianth tubes bell- N.

Hosta vingeri S. B. Jones is distinct from H. jonesii by having ovate, adaxially lustrous leaves; delicate raceme of flowers spread around the cen- tral axis of the inflorescence; decurrent, flat bracts; relatively longer pedicels; and distinct, exserted 3+3 stamens. The new species is named in honor of Dr. Samuel B. Jones, who has provided encouragement with my studies of Hosta. I thank Dr. Richard A. LaFleur for correcting the Latin description and Nancy C. Coile for comments on this manuscript. I also thank Dr. N. Fujita, Dr. H. Obha, and Mr. Haynes Currie for discussions on the classification of Hosta. Spe- cial thanks go to my parents, Mun Su and Jeom Ryo Chung, my wife, Min Suk Chung, Mr. Jong Sae Son, Seok Myeon Lee, and Chin Seop Hwang for their company on field trips.

Although this distinctive new species resembles species of Mandevilla, it belongs to Allomarkgra- fia, which differs from Mandevilla primarily in the paniculately branched inflorescence. However, this species is not at all close to 4. plumeriiflora Woods., with which it was first identified. Among the obvious ANN. MISSOURI Bor. GARD. features differentiating A. laxiflora from A. plu- mertiflora are the very openly branched inflores- cences with small bracts, very differently shaped, narrower flowers, and narrower leaves. dllomarkgrafia laxiflora is probably more closely related to 4. foreroi ^. Gentry and 4. ovalis (Mgf.) Woodson. Colombia, and both of which have similar laxly both of which occur in. Chocó, branching inflorescences. The new species differs vegetatively from both of these species in having very obscure leaf venation like that of 4. plume- riiflora. The distinctive corolla shape of 4. laxi- flora likewise helps separate it from its two probable closest relatives. In 4. ovalis the corolla is broadly (vs. narrowly) infundibuliform-campanulate above FIGURE 1. 34939) 4llomarkgrafia laxiflora (Gentry et al. 76: 923-924. 1989. 924 Annals of the Missouri Botanical Garden the basal tube, and in 4. foreroi it is more narrowly campanulate above the basal tube, which is longer and narrower than that of the new species. Allo- markgrafia foreroi differs further from A. laxi- flora in having slender, more tenuous inflorescence branches; longer, thinner calyx lobes; and differ- ently colored flowers (white with upper tube green- ish and lower tube reddish). There are only two other Allomarkgrafia species in addition to those discussed above: Peruvian 4. tubiflora Woodson ex Dwyer has leaves like 4. ovalis and a longer campanulate upper corolla tube much like that of many Bignoniaceae, while Costa Rican 4. brenesiana Woods. has white flowers with a gradually and narrowly infundibuliform upper part of the corolla tube. Another Costa Rican species described by Woodson is conspecific with 4. plu- meriiflora. Thus from a bitypic genus (Woodson, 1933) Allomarkgrafia has now grown to six spec les. As currently. known, with four out of the six species occurring in trans- Allomarkgrafia laxiflora and A. ovalis is wide- it is strongly Chocó-centered, Andean Colombia: A. foreroi are endemic to Choco; ranging from Amazonian Peru to Panama; and 4. plumeriifiora ranges from trans-Andean Colombia to Nicaragua. The two localized outliers are 4. brenesiana at middle elevations in Costa Rica and A. tubiflora in upper Amazonian Peru - 950 m The species of Allomarkgrafia may be sepa- rated by the following key: la.

Gentry, P.O. Box 299, St. Louis, CHROMOSOME NUMBER IN WALLERIA (TECOPHILAEACEAE) The small African genus Jf alleria, comprising three species (Carter, 1962), is generally consid- ered to be allied to the Lilialean family Tecophi- laeaceae. The five core genera of Tecophilaeaceae, Tecophilaea, Zephyra, and Conanthera (all Chil- ean), Odontostomum (Californian), and Cyanella (southern African), are small seasonal perennials united by their tunicate cormous rootstock, basally clustered leaves, racemose inflorescences, and flow- ers with poricidal anthers, partly inferior ovary, and subulate style with a punctiform stigma. In addition, the pollen grains have an operculate sul- cus and tectate-columellate ektexine (Simpson, 1985), and the smooth seeds have a multilayered testa with a black, phytomelan-encrusted outer lay- er. As treated by Hutchinson (1934), the first mod- ern phylogenist to recognize the family, Tecophi- laeaceae also included the African. Cyanastrum, now generally treated as the sole genus of Cy- anastraceae (Dahlgren et al., 1985; Simpson, 1985). In 1959 Hutchinson transferred Walleria to Tecophilaeaceae from Liliaceae- Dianelleae (Hutchinson, 1934). Dahlgren et al. (1985: 165) accepted Walleria in Tecophilaeaceae with res- ervations; Dahlgren & van Wyk (1988) concluded that it did belong in the family, although they placed it in its own subfamily, Wallerioideae. Walleria is discordant in Tecophilaeaceae for several reasons. The rootstock is a fleshy naked tuber, the leaves are cauline (not basal), the inflo- rescence is foliose, and the ovary is completely superior. Also, the seeds are warty and dark brown, not smooth and black, and it is uncertain whether they contain phytomelan (Dahlgren & van Wyk, 1988), although this is said to be absent by Huber (1969). Simpson (1985) demonstrated that the pol- len grains of Halleria resemble those of other Tecophilaeaceae in having a medial apertural oper- culate sulcus and an endexinous basal layer of the operculum and aperture border. Although the oper- culum of Walleria differs from other Tecophilae- aceae in being very scanty and in having a granular (vs. tectate-columellate) ektexine, its basic. struc- tural similarity with that of the core genera of the family supports inclusion of If alleria there (Simp- 1985). Embryologically, W'alleria differs in son, ANN. having mostly campylotropous ovules (anatropous in other Tecophilaeaceae) and a large embryo (Dahlgren & van Wyk, 1988). With this back- ground in mind, we undertook this investigation of the chromosome number in the two tropical African members of the genus, previously unknown cyto- logically. MATERIALS AND METHODS Root tips were harvested at mid-morning from greenhouse-grown wild-collected material, tubers of W. mackenzii and seeds of IF. nutans. The tips were placed in saturated aqueous mono-bromo- naphthalene, and left at room temperature for four hours before fixation in 3: 1 absolute ethanol- gla- cial acetic acid for two minutes. After hydrolysis in 10% HCl for six minutes at 600°C, portions of the tips were squashed in FLP orcein (Jackson, 1972). Voucher data are as follows: the apical Walleria nutans Kirk — Namibia. Gobabis: Stein- ausen road, Goldblatt & Manning 8802 W. mackenzii Kirk — Malawi, Zomba district, near Thondwe village, Goldbatt 7519 ( OBSERVATIONS AND DISCUSSION The diploid chromosome number in both species of Walleria examined is 2n = 24. The chromo- somes are of moderate size, 2-4 um in the method used. The chromosomes are mostly acrocentric but four of the smaller pairs are sub- ete as Basic chromosome number in Te is probably = 12 rnduff, 197 9: Cink 0). C nets has predominantly n = 12 or 24 ca a population of C. hyacinthoides has n 14, and one Pp of C. lutea has n = (Ornduff. 1979). the New World genera ex- amined ae Tecophilaea has n = 12 (La Cour, 1955) and Odontostomum n = 10 (Cave, 1949, 1970). The chromosome cytology of Wal- leria thus accords well with Tecophilaeaceae and, viewed in conjunction with data reviewed above, supports its placement here. Missouni Bor.

Although I can see no way to distinguish sterile material of D. clusufolia from D. paniculata, seemingly minor differences in the staminate flowers, along the lines indicated by Ma- guire (1977) and D'Arcy (1978), do hold up for the many new collections of the latter species, which is restricted to Colombia, Panama, and Costa Rica. However, contrary to somewhat inaccurate and contradictory interpretations of prior authors, the flowers of both species have two bracteoles; the internode between the bracteoles and sepals is shorter in D. clusiifolia than in D. paniculata. In addition to differences in the staminate flow- ers, the fruits of D. clusiifolia appear to have somewhat longer stigmas (or at least they persist longer) and are slightly larger at maturity. than those of D. paniculata.

(BM Robson (1958) discussed the logical error in maintaining Rheedia separate from Garcinia, es- sentially saying that no basis for separating them exists. Previously, Garcinia was not considered to occur naturally in the New World, only Rheedia. Features thought to distinguish Rheedia from Gar- cinia (number of perianth parts and degree of fusion of the stamens) are not constant in Rheedia and occur in both genera.

Recent comparative work within the family supports Robson's position (P. Stevens, pers. comm .). Seemann's epithet (edule) cannot be transferred to Garcinia as it would create a later homonym. Rheedia intermedia clearly belongs in Garcinia and provides the oldest available epithet for the spec ies. Garcinia intermedia is the only Central Amer- ican member of the genus with a soft, edible, exo- carp. All others have a thick, tough, inedible exo- carp and delicious, white, acidic, sweet endocarp (as in the mangosteen, Garcinia mangostana L.). Leaf sizes and shapes are variable in the species and encompass the narrow-leaved material named as Rheedia tonduziana. Garcinia macrophylla C. Martius, Flora 24. 2 Beibl. 35. 1841.

CHROMOSOME NUMBER IN PHENAKOSPERMUM AND STRELITZIA AND THE BASIC CHROMOSOME NUMBER IN STRELITZIACEAE (ZINGIBERALES) Chromosome counts are available for most Afro- Madagascan members of Strelitziaceae but until now the neotropical Phenakospermum has been unknown cytologically. Chromosome cytology of the small southern African genus Strelitzia is com- paratively well known. The two acaulescent species 5. reginae Ait. (syn. S. parvifolia Ait.) and S. juncea Link (possibly only a form of S. reginae) l4; in contrast, the caulescent S. alba (L.f.) Skeels (syn. S. augusta Thunb.) has 2n = 22 (Table 1). The closely related 5. nicolai Regel & Koern., also caulescent, has been reported by Sató (1948, 1960) as having 2n caudata R. A. have diploid numbers of 25 — = 14. The remaining species, S. Dyer, is unknown cytologically. It has seemed puzzling that the chromosome number of S. nicolai corresponded with the two acaulescent species rather than with the allied cau- lescent 5. alba, particularly as the merit of main- taining the two species as separate (Geldenhuys, pers. comm.) is in some doubt. We have now es- tablished that at least one Transkeian population of S. nicolai has the same chromosome number, 2n — 22, as S. alba. T [he chromosome number in 22. Phenakospermum is also 2n — MATERIALS AND METHODS Seeds collected in the wild were germinated in the greenhouse. Actively growing root tips were harvested at mid morning into saturated aqueous mono-bromo-naphthalene and left at room tem- perature for four hours before fixation in 3:1 ab- solute ethanol-glacial acetic acid for two minutes. After hydrolysis in 10% HCl for six minutes at 60°C, the apical portions of the tips were squashed in FLP orcein (Jackson, as follows: Phenakospermum guianensis Aublet 1972).

Encephalartos voiensis lives in isolated moun- tains surrounded by dry savanna in which species of Encephalartos do not occur. The new species ccurs on steep rocky slopes cloud forest at s -1,800 m elevation as an understory plant. It also grows in partial shade and full sun areas of forest clearings. Encephalartos voiensis shares some characters with E. en E. gratus Prain, E. hildebrand- tii A. & Bouché, and F. are all ihe in the same general vicinity (Fig. 1): tegulaneus, which and, to a lesser extent, it resembles FE. manikensis (Gilliland) Gilliland and its allies in Central Mozam- bique and in Zimbabwe. Encephalartos votensts shares different features with each of these taxa. For example, foliage characteristics are closest to E. bubalinus and (especially) E. hildebrandtii in that 1—5 spinose teeth are present on the basal curve of the superior margin of the median pinnae, and at least one spinose tooth is present near the basal portion of the inferior margin. Encephalartos voiensis differs from these two species by having subfalcate, very abruptly cuneate basally, very dark green to blue-green leaflets, and the transition to Annals of the 936 Missouri Botanical Garden A Volume 76, Number 3 1989 Notes 937 reduced leaflets in the lower l6 of the rachis is abrupt rather than gradual. Encepha sis can be distinguished further from E. bubalinus lartos voien- because the former has median leaflets 4 (vs. 1— 2) cm wide, 25-40 (vs. 10-20) em long, and gradually acuminate (vs. acute) apices. In general, in E. hildebrandtii, the median leaflet apices are in E. contrast, they are always pungent. Moreover, the either bifurcate or trifurcate; volensis, by median leaflets of E. hildebrandtii have up to nine spinose teeth along each margin; in £. votensis these teeth are reduced to barely discernible callose bumps. The mega- and microsporangiate strobili of Æ. volensis resemble those of E. bubalinus, E. gratus, E. hildebrandtii, and E. tegulaneus with respect to overall size, shape, and color. There are, how- ever, significant differences in mega- and microspo- rophyll characters. As in vegetative characters, £F. votensts shares individual characters with each of the aforementioned species, but none that is com- mon to all except perhaps the presence of inferior and sagittal crest tubercles.

The overall appearance of the megasporophylls of E. voiensis in shape and arrangement of the bulla facets is most similar to those of E. hildebrandtii. Compared with the pre- viously discussed taxa, the lateral lobes of the bulla of E. and appear laterally compressed in the ab-adaxial voiensis are uniquely smaller and thinner ane.

Encephalartos voiensis has a median facet on the ab- and adaxial bulla a these median facets are not present in £. gratus. Encephalartos voiensis exhibits little bl except that some leaflet characters appear to be associated with habitat differences. The leaflets of plants growing in deep shade are thinner in texture and barely subfalcate, and they generally have fewer and smaller marginal spinose teeth. Only shade plants exhibit these features, and they would most likely change under exposure to higher light intensities, as Stevenson et al. (1986) observed in Ceratozamia latifolia under otherwise similar con- ditions. Even though the relationship of Æ. votensis is not completely clear, it is our opinion, based on vegetative morphology, that Æ. closely related to E. hildebrandtii. vOlensis is most This is because in the cycads, in general, vegetative characters are more useful in separating species as, for example, 980). Macrozamia in Ceratozamia (Stevenson et al., Dioon (Sabato De Luca, 1985), (Johnson, 1959). There are several reasons for this. First, vegetative characters are always present and and often exhibit more obvious macroscopic diversity than do reproductive characters. Secondly, most data concerning reproductive characters are either fragmentary or nonexistent, and herbarium ma- terial is highly unreliable because of the vast amount of distortion of size and shape induced by drying. Thirdly, because all cycads are dioecious, we think it is important to establish vegetative characters that can be correlated with reproductive characters to establish a common denominator. In the case of the species discussed in this work, microsporoph yll and megasporophyll characters do help corroborate the species ‘delimitations indicated by vegetative Finally. changes in vegetative morphology between species of different habitats and. o same time exhibiting only subtle differences in re- characters. cycads often exhibit extreme r localities while at the productive morphology.

Fertile sta- mens 6, these representing the outer 2 whorls, ca. 5 mm long, the filament slender, ca. 4 mm long, 4-celled, the cells introrse. Stamens of the third whorl about densely pubescent, the anther glabrous, as long as the outer stamens, the filament similarly pubescent, the anther as wide as the filament and devoid of anther cells; glands present, sub-basal. Outer 9 stamens with widened bases. Staminodia (whorl IV) ca. 2.5 mm long, widened at base, filament densely pubescent, inside of the anther glabrous except for an apical tuft of hairs, the outside sericeous, the base cordate. Ovary ellipsoid, ca. 1 mm long. glabrous or with few hairs near the apex; style ca. 2.5 mm long, glabrous. Fruit un- known; tepals deciduous in very early fruiting stage. The distinctive characters of P. julianae make it difficult to place in the most recent infrageneric classification. In her revision of the neotropical species of Persea, Kopp (1966) recognized two subgenera. Subgenus Persea is characterized by its equal tepals that are pubescent on inner and outer surfaces, usually puberulous ovary, and te- pals deciduous at the fruiting stage. This subgenus includes the type species of Persea, P. americana Mill., Subgenus Eriodaphne is and three other Central American species characterized by its strongly unequal tepals with the outer tepals in- ternally glabrous, usually glabrous ovary, and per- sistent tepals in the fruiting stage. This subgenus includes about 70 neotropical species and is further divided by Kopp (1966) into four sections. Section Mutisaea includes the species with a corymbiform inflorescence; section Hexanthera includes species with only six fertile stamens (representing the out- ermost whorls), section lurataea includes species with a (sometimes slightly) pubescent ovary; and section Eriodaphne includes the remaining species, with a glabrous ovary. The species with partly or entirely two-celled stamens belong to section £r- iodaphne. Thus, the two subgenera can be readily identified in flower (tepals equal vs. unequal) and fruit (tepals deciduous vs. persistent). e usefulness of this classification of the neo- tropical Persea species is undercut by several species with characters of both subgenera. Several Central American species (for example P. albida Koster- Allen, and P. Werff) have equal tepals, which are persistent in mans, P. rigens sylvatica van der the fruiting stage. These species were included in section Eriodaphne by Kopp, but the equal tepals ANN. MISSOURI Bor. GARD. 76: 939-94]. 1989. 940 Annals of the Missouri Botanical Garden FIGURE 1. Persea julianae. — A.

As noted, the strongly unequal tepals, gla- brous ovary, and number of fertile stamens sepa- rate P. julianae from the cultivated P. americana. Specimens treated by Kostermans (1936) as P. benthamiana were included by Kopp (1966) under P. nivea Mez and are characterized by having nine fertile stamens, persistent tepals, and glaucous whitish lower leaf surfaces. Persea coriacea is an enigmatic species known only from the type collection, from the Hendrik Peak in the ma Chain, not far from the Juliana Peak. This species is described as having subequal tepals + 1.75 mm long and nine fertile stamens; these details separate it clearly from P. julianae. Kostermans (1936) also mentioned that the fruit was subtended by a small, flat cupule with an entire margin, a character not found in any other Persea species. This was probably one reason why Ko (1966) excluded P. coriacea from Persea without suggesting an alternative generic placement. The MO isotype of P. coriacea does not solve these difficulties. The label states that flower buds and fruits were collected. Presence of floral buds and fruits on the same specimen is very unusual for Lauraceae and is often the result of a disease in which galls, developed from buds, are mistaken for fruits. The buds on the MO isotype are diseased, which explains Kostermans's observation that fre- ently a staminode of the fifth whorl is present. The papillose lower leaf surface is against its in- clusion in Persea. Papillose lower leaf surfaces are common but not restricted to Aniba, but P. co- riacea does not match any Aniba species | know. I regard P. coriacea as a name based on a mon- strosity, different from the other Persea species reported from Surinam; for correct placement, ad- ditional specimens are needed. I thank Dra. M. Werkhoven for making the specimen available. J. Myers drew the illustration. LITERATURE CITED Korr, L. E. 1966. A taxonomic revision of the genus ersea in the Western Hemisphere. Mem. New York 120.

Chippendale, including an introduction and appendix, with contributions by D. J. Chippendale & S. G. M. Carr, A. S. George, K. D. Hill, L. A. S. Johnson, and P. J. Lang. Australian Govern- ment Publishing Service, Canberra. 1988. xvi + 543 pp., 111 figs. (38 color), 564 maps. ISBN 0-644-05866-8. Paper, price unknown. This recently published volume of the Flora of Australia is the first of three that will cover that arge group of trees and shrubs, the Myrtaceae. It is beautifully illustrated with numerous line draw- ings and seven pages of color photographs, is print- ed on high-quality paper, and has a good paperback binding. The volume includes a family description by A. S. George and treatments by G. M. Chip- pendale of the diverse genus Fucalyptus L Hér. (513 species) and the much smaller Angophora Cav. (7 species). George calculates that there are about 75 genera and over 1,500 species of Myr- taceae in Australia. Thus, Fucalyptus accounts for about one third of the family there. As stated in "more than any other group, e the introduction, these plants [the eucalypts ] give a distinctive char- Of course, acter to the Australian landscape. species of Fucalyptus are also planted around the world for ornamental and forestry purposes. Chip- pendale's contribution is very welcome indeed. An informative introduction relates some of the taxonomic history of Fucalyptus. The last com- plete account was that of Blakely, 4 Key to the Eucalvpts (1934), with updated editions appearing in 1955 and 1965. Until the late 1950s taxonomy was based on macroscopic characters of buds, fruits, and anthers, but since then a variety of anatomical and inflorescence features have been investigated by various workers. Presently, studies of Kucalyp- tus are appearing at an explosive rate. A quick look at the 18 issues of the dustralian Journal of Botany for the period 1984-1986 shows that not one issue was without at least one article with Eucalyptus in the title and that 59 articles on Eucalyptus appeared, 18 of which were system- atic. Thus, Chippendale's treatment is necessarily a synthesis of knowledge of Fucalyptus as it was in the mid 1980s, and it will soon be out-of-date. In fact, 24 species published while the book was being typeset could not be included. But consid- ering the history of Fucalyptus, we cannot expect another comprehensive work soon. Chippendale briefly reviews some of the features that have been used in systematic studies of Fu- calyptus, viz., stamens and anthers, cotyledons, operculum, ovules, leaf waxes, oil glands, tri- chomes, and stigma and style morphology. How- ever, his key to species depends on “readily-ob- servable characters of habit, bark, leaf arrangement and form, inflorescence, buds and fruit. ^ Near the beginning of the volume are color photographs illustrating types of bark, habit, and various species in flower. Labeling the photographs of the various bark types would have made them more useful. There are 60 pages of keys for Eucalyptus, first one dividing the species into 20 groups and then a key to the species in each group. For sys- tematic treatment the species are divided into 92 series, but these have no close relationship to the 20 groups of species in the key. A description of each series is provided with an accompanying ci- tation of type and notes on size, distribution, and distinguishing characteristics. There is no key to or synopsis of the series, but they are divided into groups in the introduction of the genus under the discussion of some of the systematically important characters. For each species are provided: a de- scription of ca. 8 lines; citation of types, synonyms, and published illustrations; a figure illustrating buds and fruits; a short list of representative specimens; and notes on distribution and distinguishing char- acteristics. Distribution maps for all species are found on 38 pages at the end of the systematic treatment. he style of the keys is very brief. Usually only one character comparison is made in each couplet and the alternatives can sometimes seem rather “adult “adult leaves arbitrary, e.g.. on page 8, lines 8 and 9 leaves more than 12 cm long” versus * less than 12 cm long”; or lines | and 2 on page 9 —“leaves green" versus "leaves glaucous or grey green or yellow green." The very first character used in the key is bark type, and bark characters are utilized at other points in the key. | experi- mented by attempting to “identify” three species I know and was able to run them through the key without problem. | was less successful with iden- tified specimens of three other species | did not know, even when I allowed myself knowledge of the bark by looking it up in the descriptions.

It obviously repre- sents many years of careful study and deep fa- miliarity with the genus. I am very happy that it has been published and recommend it to anyone with an interest in Eucalyptus. L.

GARD. 76: 945-992. 1989. 946 Annals of the Missouri Botanical Garden Avispa, and apparently from Cerro Aracamuni, were made by Felix Cardona Puig and G.C.K. & E. Dunsterville on a trip with the Venezuelan Border Commission in 1972. Coordinates used by them for what they called the ““Aracamuni section of Cerro Avispa” (01*30'N, 65?*51'W) match very closely with those from the most recent expedition to Cerro Aracamuni. Charles Brewer Carias gath- ered several plants during a stop to the summit by helicopter in 1983. Small gatherings of plants from the base and slopes of Aracamuni were made on two other occasions, in 1959 from a 900-m-tall granitic outlier of Cerro Aracamuni by John Wur- dack and Lincoln Adderley, and from an eastern escarpment of Aracamuni at 750 m by Otto Huber and Ernesto Medina in 1981. Cerro Aracamuni is the largest of the table mountains closest to Cerro de la Neblina, so ex- ploration of its summit was considered essential to help verify that the high degree of endemism re- ported from Neblina was not an artifact of incom- plete collecting. Although the summit of Cerro Ara- camuni attains an elevation of only 1,500 m, con- trasted with. 3,040 m on Neblina, most of the summit of Neblina lies between 1,800 and 2,200 m. In 1987, the Terramar Foundation of Venezuela provided Ronald Liesner of the Missouri Botanical Garden and Germán Carnevali and Francisco De- lascio of the Herbario Nacional de Venezuela the opportunity to explore the summit and slopes of Cerro Aracamuni between October 15 and No- vember 3, 1987. They gathered a total of 1,018 collections (including some bryophytes and fungi, which are not considered in this paper) from the summit and slopes. Cerro Aracamuni lies near the southern tip of Territorio Federal Amazonas, Venezuela, in Dept Rio Negro, approximately 125-140 km northeast of Cerro de la Neblina (Fig. 1). It is a small to medium-sized massif for the Guayana region, rath- er long and narrow with a north-to-south orienta- tion, extending from 01?24'N, 65°47'W to 01°32'N, 65?49'W. Vertical sandstone escarp- ments flank some of the sides, and a few rock outcrops appear on the upper edges. From its sum- mit, streams drain into the Matapire and Siapa rivers on the east, north, and south, and into the Rio Yatúa on the west. Several kilometers of low- land rainforest extend on the Rio Siapa side to the base of the massif. The large rapids, Raudal and Salto Gallineta, are prominent topographic features on the igneous outcrops along the Rio Siapa. Most of the massif is believed to be of Roraima sandstone. A close relationship with the flora of Cerro de la Neblina is expected on Cerro Aracamuni due to the proximity of the two massifs. Four of the genera previously known only from Cerro de la Neblina, Neblinanthera, Celiantha, Cephalodendron, and Neblinathamnus, are now known from Cerro Ara- camuni as well. Species (and subspecies) previously known only from Neblina, and now recorded from Aracamuni, are: Sobralia speciosa C. Schweinf., Endlicheria vinotincta Allen, Spathelia nebli- naensis R. Cowan & Briz., Diacidia glaucifolia (Maguire) W. R. Anderson, Philacra auriculata Dwyer, Tyleria silvana Maguire, Maieta nebli- nensis Wurd., Neblinanthera cumbrensis Wurd., Tococa pachystachya Wurd., Orthaea wurdackii Maguire, Steyerm. & Luteyn, Celiantha bella Ma- guire & Steyerm., Faramea boomii Steyerm., Fer- dinandusa neblinensis Steyerm., and Pagameop- sis maguirei subsp. neblinensis Steyerm. Two additions to the Venezuelan flora from the Aracamuni expeditions are Tyleria silvana Ma- guire, previously known from the Brazilian side of Cerro de la Neblina and Serra Pirapucü, and an as of yet unidentified species of the genus Jacques- huberia, previously known only from Amazonian Brazil and Colombia. VEGETATION OF THE SUMMIT The summit is covered mostly by 0.5—1-m-high, dense savanna (non-Poaceae) and low shrub vege- tation, and small forested areas occur in depres- sions and along streams. The savanna is inhabited mostly by Eriocaulaceae, Rapateaceae, Bromeli- aceae, Xyridaceae, Liliaceae, and Sarraceniaceae. Common shrubs and small trees of the savanna include Poecilandra retusa, Pagameopsis ma- guirei subsp. neblinensis, Bonnetia tristyla, Di- stictella monophylla, Emmotum glabrum, and Gongylolepis huachamacari. The patches of for- est and gallery forest include Neblinanthera cum- brensis, Aegiphila roraimensis, Clusia sp., Dia- cidia glaucifolia, Phyllanthus vaccintifolius, Psychotria duricoria, P. tapajozensis, and Ty- leria silvana.

The characters that separate the two subspecies of P. roraimae are few, yet the specimens seem quite distinct at first glance, chiefly because of the proportionally narrower leaf blade of subsp. ara- camuniense. Even the juvenile leaves of both taxa have a similar, narrow blade outline. An important difference may prove to be petiole shape, said to be terete in the Aracamuni collections; in the ma- Volume 76, Number 4 1989 Steyermark, Holst & Collaborators 951 | Venezuelan Guayana Flora— VII 14mm FIGI . & Delasci io id terial of subsp. roraimae from the Gran Sabana, it is rounded abaxially, while the adaxial surface has a median, longitudinal, obtuse angle (ridge) and two plane faces. This is the common Philodendron growing on the summit of Cerro Aracamuni, climbing up tree trunks. Its relation to P. nebulense Bunting (de- scribed from Cerro de la Neblina) remains to be determined when fertile material of the latter be- comes available.

Hexapterella steyermarkii is only the second species described in this genus. The other species, H. gentianoides Urban, is a fairly common sap- rophyte in Guyana and Surinam, and has been collected once in Venezuela—at Cerro de la Ne- blina, between 1,100 and 1,800 m. Hexapterella steyermarkii is known from three collections in Territorio Federal Amazonas (Cerros Aracamuni, Neblina, and Autana) and one from Estado Bolivar (Chimantá Massif).

EUPHORBIACEAE—contributed by Grady Webster Senefeldera yutajensis (Jabl.) Webster, comb. nov. Sapium yutajense Jabl., Mem. New York Bot. Gard. 17: 184. 1967, fig. 24. TYPE: Venezuela. Territorio Federal Amazonas: Cano Yutaje, B. Maguire & C. Maguire 35261 (holotype, NY). Jablonski noted that the leaf venation and inflo- rescence of this species suggested Senefeldera, but e placed it in Sapium because of the staminate flower with a two-lobed calyx and two connate stamens. However, the branched inflorescence, ca- ducous stipules, and especially the non-arillate seeds of the type collection are quite incompatible with Sapium. The small stamen number is shared with Senefelderopsis, but that genus has unbranched inflorescences and leaves with the veinlets not prominulous. Surprisingly, there is a resemblance to Mabea, especially to Mabea pohliana (Benth.) Muell. Arg. in sect. Apodae Pax & Hoffman (Pflanzenr. 147. V: 39. 1912). That species of Mabea has a branched inflorescence, an androe- cium of only two or three stamens, and an indu- mentum of dendritic hairs. Yet Mabea pohliana differs by having serrulate, short-petiolate leaves without prominulous venation, discrete staminate sepals and stamens, pedicellate pistillate flowers, and an elongated stylar column. In its subsessile pistillate flowers, elongated stylar column, and en- tire leaves with prominulous venation, Senefeldera yutajensis agrees with other species of Senefeld- era, and this seems the best generic placement despite the indumentum of dendritic hairs. Along with Senefeldera triandra Pax & Hoffman (Pflanz- enr. 147. XIV: 55. 1919) and possibly Mabea paraguensis Muell. Arg. (Fl. Brasil 11(2): 527 1874), Senefeldera yutajensis may represent a phyletic branch intermediate between the genera Senefeldera and Mabea Additional Ta examined. VENEZUELA. TERRI- TORIO FEDERAL A : Dept.

Licaria trinervis belongs to subg. Licaria, as defined by Kurz (1983). It does not seem to have close relatives within this subgenus; among its strik- ing characters are the brown tomentose pubescence on the young parts, depressed-globose flower shape, strongly developed basal pair of lateral veins on the leaves. Another distinction is that no other Licaria species in the Venezuelan Guayana is known from the tepui summits, although L. macrophylla (A.C. Smith) Kostermans is known from slopes of Cerro Huachamacari at 600 m, L. tomentosa van der Werff occurs on the slopes of the Chimantá Massif. Persea perseiphylla (Allen) van der Werff, comb. nov. Ocotea perseiphylla Allen, Mem. New York Bot. Gard. 10: 109. 1964 This species was known to Allen only from the holotype (Schultes & Lopez 10103, US), a spec- imen in young bud. Characters necessary for cor- rect generic placement were not discernible at this young stage, and Allen mistakenly placed the species in Ocotea. Fruiting specimens show clearly that this species belongs in Persea. Inspection of the holotype also showed that the tepals of the buds are unequal, with the outer three shorter than the inner ones, a character found in most neotropical Persea species but never in Ocotea. Hence Ocotea perseiphylla is transferred to Persea. Because open flowers have not yet been collected, P. per- seiphylla cannot be placed in any of the sections of subg. Eriodaphne Nees; the general resemblance to P. maguirei L. Kopp and P. croatii van der Werff suggests that it belongs in sect. Aurataea Kopp. It has nine four-celled stamens and therefore does not belong to sect. Hexanthera Kopp. Additional 21: ns examined. | VENEZUELA. TERRITORIO FEDERAL AMAZONAS: Dept.

However, Aracamunia differs from the other gen- era of the KEurystyles complex in its terrestrial habit, eciliate leaves and bracts, presence of lig- ulelike structures, noncapitate inflorescences, and ecristate sepals connate for about % of their length (vs. up to 4% their length). Within the complex, it seems to be closer to Eurystyles as defined by Burns-Balogh et al. (1985), but in Aracamunia the stigmas are confluent as in Pseudoeurystyles Hoehne. The most distinctive feature of Aracamunia is the presence of the ligular, apparently glandular structures that originate from the bases of the leaf sheaths and persist even after disintegration of the leaf blades and sheaths. These ligular structures are erect, rigid, solitary, or (rarely) in pairs on each leaf sheath. They show traces of vascular axes, with phloem extending farther apically than the xylem, suggesting a glandular function. The apices age dentate, or expanded into a suborbicular he multicellular hairs of the liguliform structures are denser in younger more apical por- tions, with each of the hair cells containing a large nucleus proportionate to the size of the cells. he ligular structures have vascular connections with the leaf sheaths and the stem. Further study is required to determine if they are glandular or perhaps have an assimilative function. Etymology.

This species is related to Rapatea steyermarkii Maguire of extreme southeastern Venezuela in Es- tado Bolivar. Although similar in inflorescence, in- volucral bracts, and leaf shape and size, R. ara- camuniana has filaments that are ciliolate (vs. glabrous in R. steyermarkii). The anthers, lowest bracteoles, and spikelets are longer in R. araca- muniana. The upper and lower leaf surfaces of R. steyermarkii are densely brown pubescent on the lower surface with elongate, crisp-villosulous, loose multicellular hairs, whereas in R. aracamuniana the lower surface has only brown glandular dots between smaller, pale punctations. In R. steyer- markii the upper leaf surface has short, divaricate, pointed hairs irregularly scattered on the nerves in addition to a minutely papillate surface, whereas the upper surface in R. aracamuniana is densely verruculose-papillate throughout.

Volume 76, Number 4 Steyermark, Holst & Collaborators Venezuelan Guayana Flora—VIl This new species is notable for its inflorescence of strictly one pair of flowers and its relatively large, smooth capsular fruits that are apparently nondehiscent. It is restricted to elevations above m on sandstone in southern Venezuelan Gua- yana (Cerros Neblina, Aracamuni, and Duida). It is named in honor of Bassett Maguire, Senior Sci- entist Emeritus of the New York Botanical Garden and inveterate botanical explorer of the Guayana Highland. Maguire and colleagues first. collected this species in 1954, and he first directed my at- tention to Ternstroemia as a genus in need of taxonomic study.

The growth habit of this species is somewhat unusual. From the limited material available one concludes that rosettes produce either scapes or rhizomal buds from older axillae. The rhizomes are elongate, zig-zag, and with short, evenly separated leaves. The offshoots frequently branch and ulti- mately produce new rosettes at the tips, the whole proliferating product presumably forming extensive clones. Mature seeds would be necessary to estab- lish the relationship of this to others of the section ris PRELIMINARY CHECKLIST OF THE VASCULAR PLANT FLORA OF CERRO ARACAMUNI The checklist has been arranged into two groups: pteridophytes and seed plants. Within each group, families are arranged alphabetically and are divided up into the four main areas of collection in the following order: Summit, East Escarpment, Que- brada Camp, and Granitic Dome. Within each of the collecting areas, genus and species are listed alphabetically. Each species is followed by the name of the principal collector and number.

ABSTRACT Described from the Guayana Highland are: Gongylolepis Ad Vea from Serra Aracá, Brazil, and from Sierra de Unturán and Cerro de la Neblina, Venezuela; megacephalus from Mount Ayanganna, Guyana. species of both genera is given. Stomatochaeta eolv eei is transferred to Stenopadus and Stenopadus aracaensis fro m Serra Aracá, Brazil; and Stenopadus xon are discussed and a key to the combination Stenopadus colveei is proposed. Additionally, five species from the Guayana Highland are newly documented for the flora of razil. The shrubby, homogamous, generally large- headed Mutisieae are a striking element of the Guayana Highland flora and are typically found on tepui summits. Among Guayanan taxa of its size—57 of the 6l currently recognized species (93%) are endemic to Guayana — the Mutisieae are unparalleled in their endemism level (Maguire, 1956; Pruski, 1989). The woody, hermaphroditic members of the tribe Mutisieae from Guayana fall into two main generic groups. The first group (sub- tribe Mutisiinae sensu Cabrera, 1977) consists of six genera having homogamous capitula composed of don flowers and includes Gongylole pis , with one species described herein. The nud group (subtribe Gochnatiinae sensu Ca- brera, 1977) contains four genera, which have only actinomorphic flowers within their capitula. The second group was previously represented in Gua- yana only by Quelchia N. E. Brown and Steno- padus S. F. Blake, but has been redefined to admit two new genera, equivalent in part to species for- merly placed in Stenopadus s.l. The newer genera are Stomatochaeta (S. F. Blake) Maguire & Wur- dack (1957), which was raised from subgeneric level within Stenopadus, and Chimantaea Maguire et al. (1957), which was described as new. All subsequent authors (Aristeguieta, 1964, 1968; Steyermark, 1980, 1984; Pruski, 1989) have rec- ognized Stomatochaeta and Chimantaea, the ge- neric status of which is justified by floral mor- phology. In this paper new species of Gongylolepis and Stenopadus are described preliminary to my treat- ment of the Compositae for the Flora of the Ven- ezuelan Guayana by Julian Steyermark and col- laborators, where the localities and complete synonymies of all our Mutisieae will be given. Also, fertile material of Stomatochaeta colveei, recently made available to me for study, shows that this species has the flower color and morphology typical of Stenopadus, to which it is herein transferred. GONGYLOLEPIS Gong ylolepis is a genus of 15 species with bi- labiate flowers and glabrous, reticulate, lanceolate to obovate leaves. Fourteen of these occur in the Guayana Highland and 11 are endemic to the Venezuelan Guayana. The nearest generic relative of dii us is the monotypic Eurydochus Ma- guire & Wurda leaves and eared but Eurydochus differs The two genera have similar !

STENOPADUS Described and keyed below are two new species of Stenopadus which, following the transfer of Stomatochaeta colveei to Stenopadus, raises to 14 the number of species recognized in this genus. All are endemic to the Guayana Highland and eight species are restricted to Venezuelan Guayana. Stenopadus is closely related to Stomatochaeta, which was originally described as a subgenus of Stenopadus. The yellowish corollas of Stomato- chaeta (Fig. 2A, ABE with edi erect lobes much longer than the t ti h it from Stenopadus (Fig. 2C-E), which has magenta corollas with (at maturity) coiled or flexuous lobes about as long as or shorter than the tube. By these features generic status for the two taxa is justified (Maguire & Wurdack, 1957; Pruski, 1989). Stomatochaeta colveei resembles Stenopadus in a magenta corolla with tube longer than the lobes. It was originally (incorrectly) described and illustrated as having corolla lobes stiffly erect and was thus placed by Steyermark (1980) in Sto- matochaeta. Pruski (1989) noted it as possibly intermediate between these two genera, but he retained it within Stomatochaeta until flowering o material could be observed. Specimens examined by me during a recent visit to the Instituto Botánico in Caracas show that the corolla lobes of Stoma- tochaeta colveei are flexuous and shorter than the tube (Fig. 2E). Thus, this species fits well within Stenopadus as envisioned here, and the formal transfer of this species to Stenopadus is proposed below Stenopadus and Stomatochaeta now stand 7. rnthanian Schomb. -8(9) cm, A ida surface se, involucre ca. 3-3.5 tall ca. G. polus e Maguire ; leaves 12-27 x (2.5 clearly apart from each other on the basis of flower morphology. Furthermore, Stenopadus, a genus of stately plants up to 25 m tall, is typically more robust than Stomatochaeta, plants of which are less than e m tall. Other genera from Guayana only actinomorphic flowers, and slightly less ied related to Stenopadus are Chi- mantaea, which has abaxially tomentose leaves and corolla lobes pilose when young, and Quelchia, which has small, uniflorous capitula.

Both species have three- nerved corolla lobes that are much shorter than the corolla tube and thereby closely resemble one another. However, S. aracaensis clearly differs from S. kunhardtii by nonstipitate (vs. stipitate) heads, smaller basally attenuate (vs. larger basally cuneate) leaves, and capitula that contain 25 or fewer (vs. 35-70) flowers. Also closely related is S. huachamacari, but this differs from the two mer species by two-nerved (vs. three-nerved) corolla lobes that are about as long as (vs. much shorter than) the corolla tube.

New reports are provided for 13 genera and 59 species (marked by ** in Appendix). The new reports in this paper are based primarily on material collected by R. M. King and counted by A. M. Powell and J. F. Weedin (not coded) and G. D. Carr (C). The chromosome counts have been and * respectively made from aceto-carmine or aceto-orcein squashes of microsporocytes in meiosis. Voucher specimens of the King collections are in US and a second set is in MO The previous paper in the series dealing with the Eupatorieae summarized the numbers then known from 327 of the approximately 2,000 species and 70 of the 180 genera now known in the tribe. The chromosome data were summarized again with few additions in the survey of the tribe by King & Robinson (1987). Studies subsequent to that of King et al. (1976) have added reports of ten ad- ditional genera: Urolepis n = 10 (Turner et al., 1979; Waisman & Rozenblum, 1986); Hatsch- bachiella n = 10 (Waisman & Rozenblum, 1986); Lorentzianthus n = 10 (Bernardello, Alomia n — 10 (Mabry et al., 1981; B Turner, 1986; Sundberg et al., 1986); Amolinia n — 10 (Strother, 1983); Flyriella n = 10 (Baker Sí Turner, 1986; Sundberg et al., 1986); Eryth- 16, Eupatoriastrum n = 16; Kyr- steniopsis n — 10; and Piptothrix n — ca. 17 (Sundberg et al., 1986). The present paper adds chromosome counts for the 13 additional genera: Bahianthus n — 10; radenia n — Bejaranoa n — 10; Bishovia n — ca. 10; Cron- quistianthus n — ca. 10; Fleischmanniopsis n — 10; Goyazianthus n — 20; Platypodanthera n — 10; Pseudokyrsteniopsis n — 10; Sciadocephala ' We thank Dr. Richard Wunderlin of the University of South Florida for collecting buds of Hartwrightia and Dr. Caloway Dodson of the Missouri Botanical Garden for collecting buds of Sciadocephala.

The new counts of n — ca. 20 and ca. 26 for Kaunea seem to be the first reasonably representative figures for the genus. Chromosome numbers are now known from 94 of the 180 genera. A few previously reported numbers are based on vouchers needing corrections of identification. The name Ageratina aschenborniana (Schauer) K. & R. used in earlier papers is a synonym of A. bustamenta, and Ophryosporus origanoides [Meyen & Walp.] Hieron. is a synonym of O. heptanthus. The plant reported by Coleman (1968: 235, Brazil: Coleman 295) as Ageratum cony- zoides L. is Barrosoa betoniciforme (DC.) K. & R. The general pattern of chromosome numbers in the tribe was first presented in King et al. (1976). Thirteen of the 18 subtribes had a base of x — 10 or clearly derived numbers, such as x — 15. The remaining five subtribes show higher base numbers with no remnant of x = 10. As elaborated from the chart in King & Robinson (1987), the subtribes have the following numbers with primary bases in boldface: Adenostemmatinae 5, 10; Eupatori- inae 10, 15, 20; Disynaphinae 10; Gyptidinae 10; Ageratinae 9 (Acritopappus), 10, 11, 12 (Microspermum- Piqueria-Stevia group), 15, 20, 25; Trichocoroninae 15; Ayapaninae 10; Alo- miinae 9 (Brickellia group), 10; Liatrinae 10, 20, 30; Fleischmanniinae 4 (Fleischmannia microstemon), 10, 20, 30; Critoniinae 10, 20; Praxelinae 10, 20, 29; Hebecliniinae 10, 16; Neomirandeinae 17, 20, 24, 25; Mikaniinae 16, 17, 18, 19, 20; Oxylobinae 16, 17, ca. 20, 51; Hofmeisterinae 18, 19; Oaxacaniinae 18. The pattern has not been altered by any of the more recent reports, and it is actually greatly reinforced by numerous new chromosome counts in the sub- tribes Ageratinae, Fleischmanninae, Hebecliniinae, and Oxylobinae. The only questionable additions since 1977 are in the Critoniinae and Hebeclini- inae. Questionable counts have often been over- turned by subsequent examination of vouchers, as in the case discussed under Kaunea in the Oxy- lobinae, or by reexamination of the species. The patterns seem well established, and deviations should be carefully rechecked. The significant new reports are best reviewed in the order of the subtribes established in King & Robinson (1987). ADENOSTEMMATINAE The new report of n = 10 for Sciadocephala is the first for that genus and the first in the subtribe outside of Adenostemma. Evidently both genera retain the basic number of the tribe. There has been no further evidence in the subtribe for the low n = 5 reported by Turner & Irwin (1960) from a plant now determined as 4. involucratum. Our new report for that species is n = . The two genera of the subtribe with the anomalous knob-formed pappus have now been counted, but the remaining genus Gymnocoronis, which lacks such a pappus, is still unstudied. EUPATORIINAE The Waisman € Rozenblum (1986) count for Hatschbachiella completes the survey of genera in the subtribe. All four genera show a base of x = 10, with Eupatorium (including Eupatoriadel- phus) showing some triploids and tetraploids. GYPTIDINAE The new generic reports for Bahianthus, Be- jaranoa, Litothamnus, Platypodanthera, and Trichogonia, and the Urolepis counts (Turner et al., 1979; Waisman & Rozenblum, 1986) show that n = 10 is basic to the subtribe. The recent cytological study of Gyptis pinnatifida Cass. (as Eupatorium tanacetifolium Gillies ex Hook. & Arn. by Rozenblum et al., 1988) confirms the triploid condition based on n = 10 that is already known to occur in that genus and examines details of the apomixis in the species. AGERATINAE The many new counts of Acritopappus, based on four species, strongly confirm the occurrence of n = 9 first noted for one of the species by Coleman (1970) and mentioned by King et al. 1976). The isolated occurrence of n = 9 in Ac- ritopappus is apparently consistent for the genus, with reports from both viscid-leaved and non-viscid- leaved members. Prior to the discovery of n = 9 in Acritopappus, the number was known in the tribe from only Brickellia and its close relatives in the subtribe Alomiinae. ther reports of chromosome numbers of Age- ratinae since King et al. (1976) confirmed other known patterns. New counts of Ageratum spp. show a base of 10. The Dillon & Turner (1982) report of ca. n = 10 for Ascidiogyne sanchez- — vegae Cabrera conforms with the n — 10 already known for the type species 4. wurdackii Cuatr. This further indicates the difference between the latter genus and the members of the Piqueria relationship. New reports from Piqueria and Stevia and the Strother (1983) and Sundberg et al. (1986) 1006 Annals of the Missouri Botanical Garden reports for Microspermum debile Benth. and M. nummularüfolium Lagasca conform to the already known bases of n — 12 and n — 11 in that group. The South American species reported for Stevia all have n — 11, and none show the n — 12 found in shrubby members of the genus in Central Amer- ALOMIINAE he new generic counts for Goyazianthus, Planaltoa, and Pseudokyrsteniopsis; generic counts by others for Alomia, Flyriella (Baker & Turner, 1986; Sundberg et al., 1986) and Kyr- steniopsis (Sundberg et al., 1986); and the counts for all three species of Carminatia (Turner, 1988) extend our knowledge of elements of the subtribe having the base number of 10. The Turner report for his new species, Carminatia anomala, is here attributed to the earlier name for the species, C. alvarezii Rzed. & Calderón de Rzedowski (1987). Chromosome numbers of the genera could all be anticipated on the basis of their evident relation- ships within the subtribe. The number n — 9 that is notably present in the Alomiinae in Brickellia (King et al., 1976; Keil et al., 1988), Barroetea (Sundberg et al., 1986), Pleurocoronis, and their immediate relatives is unknown in any of the pri- marily South American genera of the subtribe. LIATRINAE The new chromosome count for Hartwrightia completes the survey of the six genera of this small subtribe from the southeastern United States. All members of the subtribe have n = 10 or polyploids of that number. FLEISCHMANNIINAE The numerous new reports for Fleischmannia firmly establish n — 10 as the base for most of the species. No further examples have been found of the n — 4 that is characteristic of the weedy annual F. microstemon (Cass.) K. & R. and that has been reported for F. hymenophyllum by Grashoff et al. (1972). The counts reported in the present study formed the basis for statements regarding the polyploid complex first noted by King & Robinson (1978, 1987) in Central America. The geographically re- stricted Guatemalan species Fleischmannia bohl- manniana K. & R., F. deborabellae K. & R., and F. viscidipes (B. L. Robins.) K. & R. prove to be diploid, while the more widely distributed weedy species F. pratensis (Klatt) K. & R. and F. pycnocephala (Less.) K. & R. continue to show a consistently polyploid condition. CRITONIINAE The three new generic reports for the subtribe (Bishovia K. & R., Cronquistianthus K. & R., and Fleischmanniopsis) and the Lorentzianthus count of Bernardello (1986) show the base of n — 10 that is characteristic of all previously known members of the group. The only serious suggestion of another base in the subtribe seems to involve the presently uncounted genus Eupatoriastrum, which is noted for its paleaceous receptacles. The species belonging to this genus have been associ- ated with a similarly paleaceous species, Fupato- rium corvi McVaugh (McVaugh, 1972) of Chia- pas, which has an n = 16 (King et al., 1976). The latter is now recognized as the genus Matudina of the subtribe Hebecliniinae, and shows no detailed structural evidence of immediate relationship to ‘upatoriastrum. In contrast, structural features of Eupatoriastrum suggest close relationship to Koanophyllon, which has numerous reports of a base of n = 10 in this study and in previous studies based on Central and South American material (King et al., 1976; Keil et al., 1988). Therefor: it is surprising to see a report of n = l6 from Fupatoriastrum nelsonii Greenman (Sundberg et al., 1986). The voucher cited by Sundberg et al. from Coatepec, Veracruz (Her- nández 320) has been sought for study, but the specimen is not deposited at TEX as indicated. The actual repository, XAL, has not replied. A specimen of E. nelsonii (Hernández 355 TEX), collected from the same place, is correctly determined. The latter is the voucher for the chemical study by Bohlmann et al. (1985). It is possible that the n = 16 reported from Eupatoriastrum nelsonii is correct, and that the genus is a member of the Hebecliniinae rather than the Critoniinae. No char- acteristic of the genus precludes this. In fact, the form and texture of the corollas of Fupatoriastrum are rather like that of various members of the Hebeclinium group. Structural details indicate that placement within the Hebecliniinae, if correct, would be closer to Decachaeta than Matudina. Although the structural characters of the Hebecliniinae are less definite than those of most subtribes, there is no reason to believe that n = 16 has arisen more than once from x — 10. King et al. (1976) placed Peteravenia in the Hebeclinium group and reported chromosome numbers of n — 10 and n — ca. 17. The genus was transferred to the Critoniinae in King & Rob- Volume 76, Number 4 1989 Robinson et al. 1007 Chromosome Numbers in Compositae, XVI inson (1987), where the report of n — ca. 17 was rejected from the genus as the voucher proved to be Ageratina subinclusa (Klatt) K. & R. Two new counts further establish n — 10 as the base number for Peteravenia. PRAXELINAE New reports for Chromolaena and Praxelis (Ap- pendix) and reports in recent literature (Sundberg et al., 1986) show the trend already known for high chromosome numbers and irregular meiosis in the subtribe. HEBECLINIINAE King et al. (1976) noted the Hebeclinium group for the presence of two distinct base numbers, x = 10 and x = 16. The members of the subtribe with n = 10 were Hebeclinium and the South American species of Bartlettina. In contrast, the Central American genera Erythradenia (Sundberg et al., 1986), Decachaeta, and Matudina, and the Central American species of Bartlettina showed n — 16. The geographical pattern seemed to be most- ly South America versus Central America, with Hebeclinium being basically South American. Sub- sequent reports have generally confirmed the pat- tern. Strother (1983) reported n — 16 for four Central American species, Bartlettina breedlovei K. € R., B. pansamalensis (B. L. Robins.) K. & R., B. pinabetensis (B. L. Robins.) K. & R., and B. tuerckheimii (Klatt) K. & R., and the same number was reported by Sundberg et al. (1986) for B. hintonii K. & R. In an apparent exception to the characteristic n — 16, two Central American species of Bartlettina tamaulipanum (B. Turner) K. & R. and Eupatorium xalapanum B. Turner (7 B. brevipetiolata (Schultz-Bip. ex Klatt) K. & R.) have been reported as n = 10 (Turner, 1985). The types have been seen, and they are clearly members of the Central American complex in the genus. The reports of n — 10 are greatly in need of confirmation. The only basically Central American element of the Hebecliniinae presently known with n = 1 seems to be Amolinia heydeana (B. L. Robins.) K. & R. reported by Strother (1983). NEOMIRANDEINAE New reports for this monogeneric tribe include one species of each subgenus of Neomirandea. The reports of n = 17 for N. eximia agree with earlier counts. The reports of n = ca. 26 for N. angularis are the first of that number in the genus, but they offer limited consistency in a member of the typical subgenus of Neomirandea, which has previously been reported variously as n — 20, n — ca. 24, n — ca. 25 (King et al., 1976), and the species has recently been reported as n — 25 by Sundberg et al. (1986). OXYLOBINAE Reports since King et al. (1976) have provided an expected count of n — ca. 17 for Piptothrix (Sundberg et al., 1986) and supported previously known chromosome patterns of n — 16 for Oxy- lobus (Turner & Kerr, 1985) and n — Ageratina subgenera Ageratina, Neogreenella, and Klattiella (Jansen et al., 1984; Sundberg et al., 1986). Strother (1983) noted a minor Ss } 17 in ture of n = 18 for Eupatorium subp (= Ageratina subinclusa (Klatt) K. & R. The present study, Jansen et al. (1984), and Waisman & Rozenblum, (1986) give further examples of the subgenus Andinia, i.e., Ageratina ampla (Benth.) , A. dendroides, A. pseudochilca, A. Dr. (Hieron.) K. & R., 4. angustifolia (H. B. K.) K. € R., 4. dee (Benth.) K. & Ry A baccharoides (H. B ) K. & R., and 4. elegans (H. B. K.) K. & E ue counts confirm the consistent n — ca. 40 and n — ca. 42 already seen by King et al. (1976) in the subgenus except for the higher polyploid n — ca. 90 count for 4. angustifolia by Waisman & Rozenblum (1986). The new count of n = ca. 20 for Kaunea ig- norata seems to reinforce the generally high num- ber 2n — near 45 found by Royce Oliver in root tips of that species (King & Robinson, 1980). The new report of n = ca. 26 for Kaunea lasioph- thalma conflicts with an earlier report of n — 10 for Eupatorium lasiophthalmum Griseb. (Turner et al., 1979), but the voucher for the latter report has been examined and proves to be Lorentzian- thus viscidus, a species known to have an n — 10. It seems that Kaunea characteristically has a chromosome number at the level of n = 20-26, which is consistent with higher known members of subtribe Oxylobinae. The higher numbers in Kaunea are reminiscent of those of another Andean member of the subtribe, tina subg. Andinia. Nevertheless, the numbers in the two groups do not seem to be the same, and if other aspects of the plants are any indication of relationship, the higher numbers evidently origi- nated separately. Structurally, Kaunea seems to be one of the most divergent elements of the Oxy- lobinae, and it is not now considered close to any numbers in other Agera- part of Ageratina. 1008 Annals of th Missouri Botanical Garden LITERATURE CITED , D.

ABSTRACT The Ranunculaceae Juss. are distributed worldwide. place in the vast territory of Eurasia during the Paleogen time. The western and eastern floristic centers in eastern Pes played the m differentiation (i.e., formation of most g primary differentiation of this family apparently m at least 50 million years ago The aim of this paper is to analyze the role of the Ranunculaceae with respect to floras around the world and to define more precisely some ques- tions concerning the origin and differentiation of e, there is no general study of the geo- graphical distribution of the Ranunculaceae as a whole, except those of Tamura (1966-1968), whose data on the presence of species in the various floristic regions of the earth were helpful in pre- paring this essay. Additianalys we took advantage of our own herba rium t from KW, LW, LWS, LE, TBI, TAD, BP, and others) and the observations of the senior author ai w the iterpaetaticd of the floristic re- gions tep provinces (Table 1 and map) by T tajan (1970, 1978) and the interpretation d en- in the sense of Tolmachev (1974). Furthermore, we have attempted to recognize local, disjunctive, and widespread endemic species within each province or region. GEOGRAPHICAL CHARACTERISTICS OF THE ANUNCULACEAE The Ranunculaceae comprise 55 genera and about 2,200 species (Takhtajan, 1987; Tamura, 1966-1968; Ziman, 1985). About 20 genera’ and 1,200 species are endemics (Table 2). Some en- demic genera, e.g., Beesia, Souliea, Kingdonia, Asteropyrum, and Xanthorhiza, are morphologi- cally isolated within the Ranunculaceae, and thus we were able to use their areas to discuss pecu- liarities of the distribution and the differentiation of the family as a whole. To date, five floristic regions, the Eastern Asiat- ic, Atlantic North American, Andean, Chile-Pa- tagonian, and Irano-Turanian, contain at least one endemic genus. Most genera of Ranunculaceae have disjunctive distributions. Some, e.g., Calathodes, Dichocar- pum, Urophysa, Semiaquilegia, Beesia, Souliea, and Kingdonia, occur within restricted geographic ranges of two to four provinces in one region.

Volume 76, Number 4 1989 Ziman & Keener 1013 Geographical Analysis of Ranunculaceae phis, Paraquilegia, and Callianthemum, is char- acterized by more or less widely disjunctive areas, occupying two to four regions of Eurasia. Areas of a third group, which includes Trollius, Actaea, Cimicifuga, Enemion, Pulsatilla, He- patica, Halerpestes, and Trautvetteria, are rep- resented in three to seven regions of Eurasia and North America. In many cases the disjunctive species of these genera are considered as relicts of the Tertiary temperate flora (Thorne, 1973). Species of Caltha and Myosurus are widely distributed in the Northern and Southern hemi- spheres. It is remarkable that they are widespread in temperate areas but absent in the tropics and subtropics. The distributional patterns of the remaining 18 genera of Ranunculaceae are unbroken or nearly unbroken. Species of the majority of them occur in two to six regions of Eurasia (Aconitella and Ficaria), Sout America (Hamadryas), Africa (Knowltonia and Clematopsis), Eurasia, North Africa and North America (Nigella, Aconitum, Consolida, Aquile- gia, Adonis, Ceratocephalus, and Coptis). Del- Southeastern Asia (Varavelia), phinium occurs in 11 regions of Eurasia, Africa, North America, and South America; Thalictrum occurs in 16 regions on these continents. Species of Anemone, Clematis, and Ranunculus are wide- spread in both hemispheres in the floras of about 30 regions. REGIONAL DISTRIBUTION OF THE RANUNCULACEAE In following Takhtajan (1978) we examined the distribution patterns of the Ranunculaceae in six floristic kingdoms, eight subkingdoms, 34 regions, and about 150 provinces. HOLARCTIC KINGDOM Location: territories of the Northern Hemi- sphere (more than half of the Earth), including Europe, extratropical Asia, North America, and North Africa. Climate: predominately temperate, partly sub- tropical, and cold Ranunculaceae: 49 genera, 2,000 species. Boreal Subkingdom This subkingdom includes four regions: Eastern Asiatic, Circumboreal, Atlantic North American, and Rocky Mountain. Location: extratropical Eurasia and North America. Ranunculaceae: 48 genera, 1,500 species. Eastern Asiatic Region Location: main part of continental China, north- ern India, Burma, and Nepal, almost all Japan and Korea, eastern U.S.S.R Climate: warm temperate to mostly temperate. Ranunculaceae: 38 genera, 900 species; 12 endemic genera, 400 endemic species. Sikang Yunnan Province Location: highlands; main part of the Chinese provinces Szechwan, Kweichow, and Yunnan, also northeastern Burma and northern Laos. aracteristic vegetation: mountain conifer- ous, broad-leaved and rain forest, subalpine, and alpine formations. Ranunculaceae: 28 genera, 400 species (14, 42, 48, 66, 81, 84, 109, 112, 199, 316). Related floras: Central Chinese (21/60) and Eastern Himalayan (19/70). Observations: 8 endemic genera, 180 endemic species. All endemic genera are isolated morpho- logically within the family. For example, Astero- pyrum (A. peltatum) represents the monotypic tribe Asteropyreae and differs from other species by having simple peltate leaves. One other genus, Souliea (S. vaginata), belongs to the tribe Cimi- cifugeae and is distinguished by a unique type of ollen grain which lacks a primary germination apparatus (171). Another endemic monotypic ge- nus, Kingdonia (K. uniflora), is exceptional by having open dichotomous foliar venation (42). This genus makes up the monogeneric tribe Kingdon- ieae, subfamily Kingdonioideae.* also Urophysa henryi, Beesia calthifolia, athodes palmata, C. polycarpa, and C. oxycarpa, occur in isolated mountain forest locations at 2,000— 4,000 m of the Sikang Yunnan, Central Chinese, Eastern Himalayan, and some other provinces. Disjunct areas of species of Semiaquilegia (S. adoxodoides and S. manschurica) and Dichocar- pum (D. fargesii, D. dicarpon, and others) are widely separated in provinces in the west and the east of the Eastern Asiatic Region. These species are also mountain forest plants, restricted to shade locations. * Some family, Kingdoniaceae. systematists consider Kingdonia to belong to the Circaeasteraceae or else classified in its own monotypic 1014 Annals of the Missouri Botanical Garden TABLE |.

AUSTRALIAN KINGDOM 5 50 30 East Australian Region 5 45 30 Southwest Australian Region 2 5 2 Central Australian Region In the flora of the Sikang Yunnan Province, Aconitum has about 70 species of which 40 are endemics; Delphinium has 70 species and 50 en- demics; Clematis has 40 and 20; Anemone 20 and 15; Trollius 10 and 8; and Aquilegia 8 and 9 species. In this province occur species that are important in considering the origin and dispersion of their genera and the family Ranunculaceae as a whole. For example, Aconitum gymnandrum, which rep- resents the monotypic subg. Gymnaconitum, is found at about 4,000 m in Szechwan and in the Eastern Himalayan Province. Its annual habit is unique within Aconitum; this species is character- ized by having primitive flowers and is considered a Tertiary relict (181, 241, 284). Another prim- itive species, Delphinium aconitoides, also occurs in this province. The local endemic Clematis ran- unculoides, occurring there, represents the mono- typic sect. Ranunculoides, and its life form (ro- sette-forming perennial herb with tripartite leaves) is regarded (341, 342) as the most primitive within Clematis. There are three monotypic endemic sections of Anemone: sect. Rivularis (A. rivularis), sect. Ane- moclema (A. glaucifolia), and sect. Begoniifolia (A. begoniifolia). Moreover, the most primitive and simultaneously relict species of Trollius (T. yunnanensis) (64, 270) and Aquilegia (A. ecal- ta) in the Sikang Yunnan Province (272). The few species endemic to this province include Delphinium ceratophorum, Ranunculus platy- petalus, and Thalictrum delavayi; many other species are shared with adjacent provinces.

Observations: 10 endemic species (e.g., Del- phinium propinquum, Ranunculus pamiri, Tha- lictrum ruthifolium). The flora of the Eastern Asiatic Region is an extraordinary mixture of tropical and temperate elements, and is considered (296, 297) as the most significant center of development of the Angio- sperms, possibly the area of origin. ithin this region the flora of the Sikang Yun- nan Province is extremely rich with Angiosperms; therefore, some Soviet plant geographers (159, 38) regarded Southwestern China as the cradle of the modern temperate flora of Eurasia and considered the latter as derived from an ancient tropical flora. Other botanists (78, 107, 109) sug- gested that the primary development of the tem- perate mesophytic forest flora of Eurasia took place within the Eurasiatic tropical flora, possibly within Southwestern China, which has been the greatest refugium for this temperate flora. According to the paleobotanical data (131), since Late Cretaceous time the Sikang Yunnan flora was mainly a high-mountain one, which included many temperate elements. The Yunnan Plateau is one of the most ancient mountain systems, formed in the Late Cretaceous (Yanshan movement of the earth crust— 224), while the Himalayas are much more recent and belong to the alpine stage of mountain development (192). Therefore, the East- ern Himalayan flora is considered young (297). 280) claim that significant refugium of Some plant geographers (13, the Manchurian flora was a the Tertiary warm temperate forest flora and sug- gest that the former coniferous-broad-leaved me- sophytic forests, in which temperate elements now predominate, migrated there during the Miocene and changed since. According to Maekawa (190), a warm temperate flora developed in Japan and Korea since the Oli- flora of Manchuria has scarcely gocene-Miocene. Tanai (304) claimed that the me- sophytic coniferous-broad-leaved forests that sur- vived there are quite similar to those in Manchuria. Our analysis of the role of the Ranunculaceae in the provincial floras of the Eastern Asiatic Re- gion led us to postulate that the initial differentia- tion of many groups of this family took place there in two diverse floristic centers, western and eastern ones. The former includes the Sikang Yunnan, Eastern Himalaya, and adjacent territories, the latter coincides with Manchuria, Japan, and Sa- alin. The western floristic center consists of ten en- Asteropyrum, Urophysa, Kingdonia, Beesia, Calathodes, Semiaquilegia, and Dicho- carpum, are distributed disjunctively in two to four 1030 Annals of the Missouri Botanical Garden provinces of eastern Asia and only Archiclematis and Paroxygraphis are local Eastern Himalayan endemics. Most of the endemic ranunculaceous species within the western floristic center of eastern Asia are high mountain plants, and in this area a number of species are shared with two or three adjacent provincial floras. There are 22 genera and about 60 species ees about 20 endemics) in com- mon with the Sikang Yunnanian, Eastern Hima- layan, and Central Chinese provincial floras. These floras consist of the most primitive species of Trol- lius (T. yunnanensis), Anemone (A. rivularis), Clematis (C. ranunculoides), and Aquilegia (A. ecalcarata), and all of these genera include sec- tions endemic to the western part of eastern Asia. Compared with the eastern floristic center, the western one is home to species of the disjunctive Eurasiatic genera Helleborus, Paropyrum, Par- aquilegia, and Oxygraphis. All these facts confirm our opinion concerning the close connections of the floras of the previously entioned western provinces of eastern Asia. In i region of these western provinces during past geological periods a single high-mountain flora ex- isted which became a center of development for several genera of the Ranunculaceae (all ten en- demic genera, also Trollius, Aconitum, Aquilegia, Anemone, and Clematis). We do not consider the Ranunculaceae in the Eastern Himalayan Province as consisting of young species; rather, we support the opinion of van Steenis (289) about their antiq- uity. The eastern floristic center in eastern Asia con- sists of four endemic ranunculaceous genera and about 120 endemic species. Two endemic genera, Semiaquilegia and Dichocarpum, are shared with the western center and the other two genera, Ane- monopsis and Miyakea, are local endemics. Most endemic species of Ranunculaceae in the eastern part of eastern Asia are montane forest plants. There are 17 genera and about 25 species shared by Manchuria, Japan, and Sakhalin, but there are almost no endemic species shared by two or three provinces. These floras consist of endemic sections of Cimicifuga, Anemone, Pulsatilla, Clematis, and Coptis. In contrast to the western floristic center, in the eastern center occur species of the disjunctive Palearctic genera Enemion and Trautvetteria, comparatively few species of Del- phinium (absent in Japan and Sakhalin), and com- paratively few Clematis species (especially few in Manchuria). A comparison of the roles of the Ranunculaceae in the provincial floras of the western and eastern parts of eastern Asia indicated that only one-third of the ranunculaceous genera are common to both areas (Caltha, Trollius, Actaea, Cimicifuga, Aconitum, Delphinium, Aquilegia, Anemone, Pulsatilla, Adonis, Thalictrum, Ranunculus), and all of them are shared with the flora of the Cir- cumboreal Region. The facts obtained as a result of our analysis are probably best explained on the basis of the hypothesis that the Ranunculaceae probably orig- inated in the vast land mass of Eurasia, with east- ern Asia as a most significant center of secondary differentiation and conservation of many ranun- culaceous genera. There were two centers of for- mation for genera and species of Ranunculaceae, western and eastern, which developed rather in- dependently, though some groups migrated from one to the other. In our opinion, in the high-moun- tain flora of Sikang Yunnan, the Eastern Hima- layas, and adjacent territories the endemic genera Asteropyrum, Beesia, Calathodes, Souliea, Uro- physa, Kingdonia, Archiclematis, and Paroxy- graphis evolved, as did such genera as Trollius, Aquilegia, Anemone, and Clematis. Meanwhile, in the montane forest flora of Manchuria, Japan, and adjacent territories, the endemic genera Ane- monopsis, Miyakea, Semiaquilegia, and Dicho- carpum evolved. Plant geographers (77, 136, 166) regarded the Altai as the refugium of the Tertiary nemoral relicts and one of the important centers of development of the high-mountain Eurasiatic flora. They pro- posed that many ancient Eastern Asiatic species migrated westward through the Altai. Our data on the Ranunculaceae confirm the importance of the Altai flora in the development and distribution of many Eurasiatic groups of Angiosperms. Further- more, endemic genera and sections of the Ranun- culaceae in the Siberian provincial floras are ab- sent, and moreover, almost no species occur in all provincial floras of Siberia. These facts can be explained if one is to Ern that contacts of Siberian floras were not clos According to Tikhomirov (308) and Vasiljev (321), the origin of Siberian taiga floristic com- plexes are recent (Pleistocene), but Tolmachev (310) claimed that these complexes were more ancient (Early Pliocene). Our data support the latter opin- ion but show that the floristic elements of the Ra- nunculaceae of the northern Siberian taiga were derived from Eastern Asiatic ones. Consequently, some Siberian species of Trollius, Aconitum, Del- phinium, Anemone, Ranunculus, and Thalictrum are considered today as boreal or taiga elements, ut they are really related to the nemoral high- Volume 76, Number 4 Ziman & Keener 1031 Geographical Analysis of Ranunculaceae mountain elements of the more warmth-loving flo- ras of Manchuria and western China. Our analysis of the Ranunculaceae of the pro- vincial floras of Europe shows the presence of 25 genera and about 250 species. Endemic ranun- culaceous genera are absent, but there are about 5 endemic species restricted mainly to the Alps, Carpathians, Pyrenees, and other highlands, and include species of Aquilegia, Aconitum, Delphin- ium, Ranunculus, and Thalictrum. The distinctive features of the European pro- vincial floras include not only the presence within them of many common ranunculaceous species but also historical connections with the Siberian and especially with the Eastern Asiatic floras. Accord- ing to Popov (236), the Eastern Asiatic and Eu- ropean floras have the same age, but our data show that the latter are derivative from the former. In our opinion, therefore, the majority of the Tertiary ranunculaceous groups have migrated into Europe from the east during the Pliocene and became preserved there in the Alps, Carpathians, and other mountains. More recently, in these territories in- tensive radiation of new groups of Aconitum, Del- phinium, and Aquilegia took place. Our data from analysis of the role of the Ra- nunculaceae in arctic regions uphold the opinion of Tolmachev (312) and Budantsev (36) concern- ing the comparatively recent age of the arctic floristic complexes and their derivation from boreal and partly from nemoral complexes. Contrary to some plant geographers (95, 314, 320) who con- sider the territory of the Arctic Province as a floristic region or a special zone without division into regions and provinces, we follow Takhtajan's (2977) interpretation of this province. aucasus was a remarkable center in the formation of some high-mountain groups of An- giosperms in the Late Pliocene and Pleistocene (77, 101, 102, 193, 293). These groups originated out of subtropical-forest species (complexes of the Pol. tava flora— 1 70), but some of them migrated there from the east, mainly from eastern Asia. We note also the presence within the modern Caucasian flora of 22 genera and about 230 species of Ranunculaceae (about 60 endemic). Almost all ranunculaceous genera in the Caucasian provincial floras are shared with those in the European and Siberian floras of the Circumboreal Region. Most species of these genera (Aquilegia, Aconitum, Del- phinium, Anemone, Pulsatilla, Clematis, and Thalictrum) occur in eastern Asia and Siberia. Some genera (e.g., Nigella, Consolida, Cera- tocephalus) occurring in the Caucasian floras are shared with the floras of the Mediterranean Region. In the flora of the Caucasus, there are some Eu- rasiatic disjuncts (e.g., Actaea spicata, Anemone nemorosa), which are generally accepted as Ter- tiary relicts. These data led us to hypothesize close connections among the ranunculaceous groups in Eurasia (including the Caucasus) during past pe- riods and to hypothesize possible migrations of their ancestral groups into the Caucasus from the east. The membership within the Ranunculaceae of large numbers of Caucasian endemics indicates lo- cal differentiation of this family in the high-moun- tain zones, especially within Delphinium and Ra- nunculus. Most of the Caucasian endemic species (e.g., Aquilegia colchica, Delphinium pyrami- datum, Anemone speciosa, Aconitum pubiceps, Ranunculus helenae) originated in the Western Caucasus (or Colkhis), which is considered to be a significant refugium of the Late Tertiary warm- temperate forest flora. Another large Tertiary flo- ristic refugium, which was in the Eastern Caucasus Hyrcan or Talysh), did not play a large role in the differentiation of the Ranunculaceae and hence — the Talysh endemic species of this family are not numerous. The evolution of the ranunculaceous flora of these two centers developed independently, and shared endemics as well as vicariant species of Ranunculaceae are almost absent. Some species of Ranunculaceae in the Caucasian floras are shared with the Mediterranean Region or are closely related to species there. They are predominately annual xerophytes (e.g., Nigella ar- ensis, Consolida ambigua, Ceratocephalus tes- ticulatus, Adonis aestivalis). The Caucasian ran- unculaceous species with connections in Anterior Asia are xerophytic and mainly annual (e.g., Del- phinium cyphoplectrum, Consolida divaricata, igella orientalis, Aconitella hohenackeri, Tha- lictrum sultabadense). At the same time, within the ranunculaceous species shared between the are high-moun- tain, mesophytic, mainly forest plants (e.g., Caltha polypetala, Trollius Aquileg caucasica, Anemone impexa, Pulsatilla RR Caucasus and Asia Minor, many ranunculinus, cea). All previously mentioned data led us to suggest close connections of the ranunculaceous groups in Eurasia (including the Caucasus) in past periods; possible migration into the Caucasus of some an- cestral groups of this family from the east through Asia Minor and some xerophytic groups from the Mediterranean Region; evolution of some groups within the Caucasian flora itse According to the literature, a flora of the Ap- palachian Province of the Atlantic North American Region is ancient (mainly Tertiary), whereas the 1032 Annals of the Missouri Botanical Garden flora of the North American Prairies and the At- lantic-Gulf Coastal Plain provinces are compara- tively recent and derivative. Our data support this conjecture, including close relationships of the bo- real floras of Eurasia with those of North America while, on the other hand, maintaining that there were relatively prolonged disconnections of the flo- ras in the western and eastern parts of both con- tinents (31, 98, 184). These floristic events were promoted by means of sea barriers (ancient Siberian Sea and the Straits of Mexico) and Miocene and more recent land bridges between Eurasia and North America through the Pacific and Atlantic oceans (135, 251). Seventeen ranunculaceous genera are shared by North American and Eurasian boreal floras. It is remarkable that more than half of them (Caltha, Actaea, Cimicifuga, Delphinium, Clematis, Anemone, Pulsatilla, Ranunculus, and Thalictrum) consist of sections with Eurasiatic— North American distributions. Although species in common to these floras are few (e.g., Anemone Aconitum, narcissiflora, Thalictrum alpinum, Ranunculus pedatifidus), pairs of corresponding or closely re- lated species are numerous (e.g., Actaea spicata- A. rubra, Trautvetteria japonica-T. grandis, Enemion raddeanum-E. biternatum). u ysis showed that the territories of the Appalachian and Rocky Mountain provinces were important centers of North American differentia- tion of the Ranunculaceae. Within the former, the Xanthorhiza, and Ane- =] E relict genera Hydrastis, monella evolved, and within both of them, some sections of Trollius, Aquilegia, Ranunculus, Tha- lictrum, Enemion, and Cimicifuga. Possibly, the two last-mentioned genera originated within these floras. Compared with the peculiarities of distri- bution of species of Hydrastis, Xanthorhiza, and Anemonella (they occur disjunctively through about ten states in the Appalachian province, e.g., Illinois, Tennessee, Virginia, and others), we regard the age of these genera (at least that of Enemion) as more recent than the Eastern Asiatic endemic gen- era (e.g., Beesia, Calathodes). A comparison of the distribution of the Ranun- culaceae in all four regions of the Boreal Subking- dom (Eastern Asiatic, Circumboreal, Atlantic North American, and Rocky Mountain) showed the con- siderable floristic role of this family in each. These data form the basis of our supposition that the development of the Ranunculaceae took place over a long period of time within the Tertiary warm- temperate flora which was in common to all cir- cumpolar territories of the Northern Hemisphere (31, 296). We regard western and eastern parts of eastern Asia and eastern North America (Ap- palachians) as significant refugia of this ancient flora. The Altai-Sayan id Alps, Carpathians, Pyrenees, Caucasus, and t ocky Mountains were, in our opinion, ee centers of the differentiation of some groups of the Ranuncula- eae. In the Madrean Region of the Madrean Sub- kingdom all ranunculaceous species are concen- trated on mountain slopes, and they are mainly members of the Californian and Mexican Highland provinces. These species are scanty in chaparral formations and absent in deserts. All genera of the Ranunculaceae are in common to those in both Eurasiatic and North American floras of the Boreal Subkingdom, but species in common are few and most of them are relict disjuncts. The mountains of California were one of the secondary centers of differentiation of Delphinium, and some groups of Thalictrum evolved in the Mexican Highlands. Our analysis of the Ranunculaceae within the Madrean Region upholds the suspected (251, 286) relationships of many northern Californian groups of species with those in the boreal floras in both western and eastern North America, and, more- over, with those in boreal Eurasia. Stebbins & Major (251) regarded Trautvetteria grandis, Del- phinium californicum, Clematis occidentalis, Anemone quinquefolia, and some other disjuncts as relicts of Tertiary deciduous mesophytic forests, although most endemic species of Delphinium have a more recent age, and our data confirm that hypothesis. It is remarkable that 15 genera of the Ranunculaceae are in common to the floras in the above-mentioned regions of the Boreal and Mad- rean subkingdoms. The modern flora of the regions of the Ancient Mediterranean Subkingdom is rather xerophytic, but the Ancient Mediterranean flora developed as a derivative and mainly migratory one from boreal and tropical mesophytic floras. Most of the Angio- sperms in the Mediterranean flora are related to corresponding Eastern Asiatic groups (Popov— 245). Within the Mediterranean Region the floras of the Liguro- Tyrrhenian and Iberian provinces are quite rich with Ranunculaceae. They are similar to the Balkanian flora of the Circumboreal Region but much different from the rest of the Mediter- ranean provincial floras. At the same time, the flora of the East Mediterranean Province is related to the most xerophytic provincial floras of the Ir- ano-Turanian Region (e.g., Mesopotamian), and within the former about half of the species of Ra- nunculaceae are annuals. Volume 76, Number 4 Ziman & Keener 1033 Geographical Analysis of Ranunculaceae Our analysis of the Ranunculaceae within the Mediterranean floristic provinces showed their xe- rophytic features (presence of many annuals and bulb plants) and clear connections with mesophytic groups of this family in the floras of the Boreal Subkingdom, especially with those in the high- mountain floras of Southern Europe. Within the Irano-Turanian Region, most Ra- nunculaceae belong to the provincial floras of the Anterior Asiatic Subregion, while in the floras of the Central Asiatic Subregion there are relatively few Ranunculaceae. Most ranunculaceous repre- sentatives are concentrated in the flora of the Ar- meno-Iranian Province, which is surpassed world- wide for the richness of the Ranunculaceae only by the Sikang Yunnan Province. Nevertheless, the number of endemic species is remarkably low, es- pecially as compared with the flora of the Sikang Yunnan Province (30/220 vs. 180/400—see Ta- ble 1). Within Ranunculaceae predominate species with boreal and nemoral affinities predominate in the floras of eastern Asia and South Siberia. These phenomena confirm the close connections between the Armeno-Iranian, South Siberian, and Eastern Asiatic floras and might reflect that the ancient flora of Anterior Asia was once more mesophytic. From an analysis of the role of the Ranuncu- laceae in the provincial floras of the Irano-Turanian Region, we note that the highlands of Middle Asia (Pamiro-Alai, Tien Shan, and others) were sites of secondary formation of some groups of this family (more than 100 endemic species of Aconitum, Delphinium, Aquilegia, Anemone, and Ranun- culus). The floras of the Turkestanian, Dzungaro- Tien Shan, and Central Tien Shan provinces are very similar in terms of Ranunculaceae. This phe- nomenon reflects the autochthonous development of the Mountain Middle Asiatic flora on the base of the ancient boreal groups of Angiosperms (Ka- melin, 140, called them the Turkmenian and the Himalayan-Mediterranean branches). According to Pavlov (227) and Vykhodtsev (329), most of the iddle Asiatic mountain endemics are recent (Qua- ternary) and progressive, while Ovchinnikov (218) claimed that within them are some relict elements of nemoral complexes with certain Eastern Asiatic relatives (e.g., disjuncts Trollius lilacinus, Del- phinium brunonianum, Hepatica falconeri, Par- opyrum anemonoides). We agree therefore wit Kamelin (140) that the Mountain Middle Asiatic flora, including the floras of the Tien Shan, is a single unit. The Armeno-Iranian and Central Anatolian pro- vincial floras are similar to the flora of the Medi- terranean Region and are much different from the floras of Mountain Middle Asia annuals (species of Consolida, Nigella, and oth- . There are many ers), but almost no endemic species of the Ranun- culaceae. Species in common to the floras of Moun- tain Middle Asia, Armeno-Iranian, and Central Anatolian provinces are few, especially within 4c- onitum, Delphinium, Aquilegia, Anemone, and Pulsatilla. Meanwhile, the two last-mentioned flo- ras include some genera and many species shared with those in the Caucasian floras but absent in both the Middle Asiatic and Mediterranean floras (e.g., Caltha polypetala, Helleborus orientalis, Actaea spicata, Isopyrum thalictroides). It is re- markable that Caltha, Helleborus, Isopyrum are boreal mesophytes with many species in both the floras of the Eastern Asiatic and Cir- cumboreal regions. The floristic richness of the Ranunculaceae in the floras of the Western Himalayan and North Baluchistanian provinces is intermediate between Actaea, and the high-mountain floras of Middle and Eastern Asia. The Ranunculaceae in the Central Asiatic pro- vincial floras, both Mongolian and Tibetan, consist of few endemic species. The outlying northeastern districts are related to those in the Altai-Sayanian and West Chinese floras. We conclude that the flora of the Ancient Med- iterranean Subkingdom played a noteworthy role in the differentiation of the Ranunculaceae largely because of the evolution of annual (Vigella, Con- solida, and Aconitella) and bulb plants (species of Within the high- mountain floras, some groups of ranunculaceous Anemone and Ranunculus). endemic species recently evolved.

There are few ranunculaceous representatives, and they occur mainly in the mountain flora of this subkingdom. Lam (177) and van Steenis (287) regarded Anemone, Ranunculus, and Thalictrum as examples of temperate genera that penetrated the Malesian tropical mountain flora from temper- ate eastern Asia through ancient mountain ridges. Our data do not challenge this idea. Possibly, the Ranunculaceae migrated through Malesia in the Southern Hemisphere by two different routes. The western route went through Sumatra, Kalimantan, and Java, and the eastern one passed through the Philippines, Molucca, Sulavesi, and New Guinea. Van Steenis (288) and Aubreville (9) supposed these groups of islands to be the distinct centers of development and dispersal of the Angiosperms: the former island group was related to the South- eastern Asiatic floristic center, while the latter group was home to part of the Australo-Papuan flora. The formation of uplands in New Guinea in the Late Oligocene limited north-to-south penetration by high-mountain Ranunculaceae (201, 202, 248). After that time some endemic groups of Clematis and Ranunculus evolved in the highlands of Ma- lesia. Areas of some species (e.g., Naravelia da- syneura, Anemone sumatrana, Clematis leche- naultiana) occur in the adjacent Indo-Chinese, Malesian, and Indian regions, while some other species (e.g., Anemone vitifolia, Clematis mey- eniana) occur disjunctively also in the highlands of West China, the Himalayas, and Japan. The most interesting area has Clematis pickeringii be- cause it includes Malesia, New Caledonia, and northeastern Australia. n the flora of the African Subkingdom only two genera are restricted to Africa and Madagascar: Clematopsis, which is related to Clematis, and The rest of the ranunculaceous genera (Anemone, Clematis, Delphinium, Nigella, Ranunculus, and Thalictrum) are shared by the floras of the Boreal and Ancient Mediterranean subkingdoms, and many species of them are related to the species of the Knowltonia, which is related to Anemone. latter subkingdom. For example, Anemone thom- sonit is distributed in the alpine and subalpine belts of Mount Kilimanjaro and a related species, 4. glaucifolia, grows in high mountains of western China. Clematis grata and Delphinium dasycau- lon are common to the floras of western China, the Himalayas, and in Hindustan. Our analysis of the distribution of the Ranun- culaceae in Africa confirms Hedberg's (117, 118) and Boughey's (27) suggested existence of the An- cient Tropical Mountain flora in Africa and the possible connections between the Afro-Alpine and Boreal floras of Africa and Eurasia in past periods. We suppose that the ranunculaceous representa- tives migrated into Africa from Eurasia by means of some ancient land bridges (e.g., Sunda, Arabian) that existed there until the Late Cretaceous and early Quaternary (246, 250, 335). Afterwards, formation of the mountain ridges in eastern Africa (dated as Miocene) promoted development of the high-mountain groups of Ranunculaceae and mi- gration of some of them into South Africa, where cold and temperate conditions existed until the Cretaceous (53). Few groups (e.g., species of Clem- atis, Clematopsis, and Knowltonia) migrated southward and secondarily became adapted to the tropical conditions of Africa CAPE KINGDOM Location: southern tip of Africa. This subkingdom includes only the Cape Region. Characteristic vegetation: predominately scle- rophyllous scrub and Ranunculaceae: 7 genera, about 30 species.

Some endemics (e.g., capensis and 4. alchemillifolia) are related to endemics in the floras of the Eastern Asiatic Re- gion. The Cape flora is extraordinarily rich and dis- tinctive (297), but the Ranunculaceae in it are rather few and are related to those in the floras of the African and Boreal subkingdoms.

Observations: 2 endemic genera and about 30 endemic species. The endemic genera, local and monotypic, are represented by Oreithales integ- rifolia and Laccopetalum giganteum, which are distributed in Peru, Bolivia, and Ecuador at about 4,000 m. Endemic species belong mainly to Ra- nunculus (about 20—e.g., R. pilosus), but some endemics include Clematis (e.g., C. albo-rosea), Anemone (e.g., A. jamesonii), and Thalictrum (e.g., T. longistylum). Summing the data of the analysis of the Ra- nunculaceae in the floras of the Neotropical King- dom, we must keep in mind that North America was separated from South America with a relatively wide sea space during Cretaceous and Paleogene time (250). On the other hand, until the Oligocene South America was joined through the subantarctic bridge with Antarctica which at that time was cov- ered with cool temperate forests (246, 248). The Andes were formed in the Pleistocene and after that they became an important transtropical bridge for the migration of temperate floristic elements from North America to South America and vice versa (211, Species of Thalictrum and Anemone multifida migrated through the Andes from the north. In fact, most of the species allied to the Andean species are distributed in North and Central America (e.g., species of Thalictrum, sects.

The Andean high-mountain flora was one of the important centers of ranunculaceous differentia- tion. There are two distinct monotypic endemic genera in this flora, Oreithales and Laccopetalum. The former is hexaploid and seems to be derived from Anemone (32, 68); the latter differs from other Ranunculaceae by possessing a large number of nectary glands and possessing large unbroken leaves (length over 40 cm) HOLANTARCTIC KINGDOM Location: territory of South America to latitude 30°S, some islands in the southern extremity and New Zealand.

Ranunculaceae: 8 genera, about 30 species. Related floras: Andean (5/10), Pampean (3/ , €g., Clematis hilarii, Ranunculus platensis) and Magellanian (3/5, e.g., Caltha sagittata, Ra- nunculus biternatus). Observations: 10 endemic species (e.g., Anem- one rigida, Ranunculus chilensis). There are some species of two endemic genera, Barneoudia (e.g., B. chilensis, B. major) and Hamadryas (e.g., H. ) argentea). Pampean Province Location: southern Brazil, partly Argentina and Uruguay. Ranunculaceae: 3 genera, about 10 species. Related floras: Chilean (3/5). Observations: few endemic species (e.g., Anem- one decapetala, Clematis bonariensis). Patagonian Province Location: southern Argentina. Ranunculaceae: 3 genera, 5 species (e.g., Ra- nunculus patagonicus, Myosurus patagonicus). Magellanian Province Location: Magellanian and adjacent islands. Ranunculaceae: 3 genera, about 15 species. Related flora: Chilean (3/5). Observations: 10 endemic species (e.g., Ham- adryas magellanica, Caltha appendiculata, C. dioneifolia). Fernandesian Region Location: Juan-Fernández and Desventuradas islands. Ranunculaceae: absent. South Subantarctic Islands Region Location: Tristan d'Acunha, Kerguelen, and ad- jacent islands. Ranunculaceae: 1 genus, 5 species (e.g., en- demic Ranunculus carolii). Neozeylandic Region Location: New Zealand and adjacent islands. Ranunculaceae: 5 genera, 60 species (5, 45, 80, 111, 196, 336). Related flora: Chile-Patagonian (5/2, e.g., Ra- nunculus acaulis, R. biternatus). Observations: about 55 endemic species (e.g., Caltha obtusa, Clematis australis, Myosurus no- vae-zelandiae, Ranunculus gracilipes). Most species occur in the South Island only, while some (e.g., Ranunculus insignis, Caltha novae-zelan- diae) are distributed in North Island and South Island. The majority of species are high-mountain plants, and a few (e.g., Clematis afoliata, Ra- nunculus rivularis) occur in low-mountain zones or plains. Our analysis showed that within the Holantarctic Kingdom the Ranunculaceae are distributed mainly in the temperate highlands or in very cold plains. Two endemic oligotypic genera, Barneoudia and Hamadryas, were formed in the Chile-Patagonian E while in the high zones of mountains of uthern South America and New Zealand some groups of the Ranunculaceae (mainly Ra- evidently from common nunculus) developed, Volume 76, Number 4 Ziman & Keener 1039 Geographical Analysis of Ranunculaceae ancestors. Fisher (80) noted the predominance of polyploids within the New Zealand species of Ra- nunculus and listed 10 pairs of alpine species with one member in New Zealand and the other member a similar South American species (e.g., R. haastii— R. semiverticillatus and R. nivicolus- R. capra- rum). Consequently, Fisher supposed that high- elevation New Zealand Ranunculus was derived from the South American one, not from Malesian species. Mountain ridges in New Zealand formed in the Late Pliocene (248), along with the rise of the mountains in Australia and New Guinea. According to Raven (248) and Wardle (334) the initial species of Anemone, Clematis, and Ranunculus arrived in New Zealand from South America in the Late Pliocene or later, while species of Caltha already spread there in the Paleogene. AUSTRALIAN KINGDOM Location: Australian continent. Ranunculaceae: 5 genera, about 50 species. This kingdom includes the Southwest, East, and Central Australian regions. East Australian Region Location: Queensland, New South Wales, Vic- toria, and Tasmania. Characteristic vegetation: high-mountain for- est and ericoid formations. Ranunculaceae: 5 genera, about 45 species (24, 37, ). Related pow Neozeylandic (2/5, e.g., Clem- atis foetida, Ranunculus rivularis) and Chile-Pa- tagonian (2/3, e.g., Ranunculus acaulis, R. bi- ternatus). Observations: about 30 endemic species (e.g., Anemone crassifolia, Caltha introloba, Clematis aristata, C. gentianoides, Ranunculus gunni- anus), and most of them are endemics of Tasmania only (e.g., Ranunculus muelleri, R. scapigeri). Southwest Australian Region Location: southwestern Australia. Characteristic vegetation: dry and rainy scler- ophyllous forests of Casuarina and Eucalyptus, also scrub. Ranunculaceae: 2 genera, Clematis microphylla, Ranunculus lappaceus). Central Australian Region Location: North Territory, Great Sandy Desert, Victoria and Gibson deserts, and other areas. 9 species (e.g., Characteristic vegetation: tropical desert and dry savanna formations. Ranunculaceae: absent. The Ranunculaceae in Australia are related to those in the Holantarctic floras. Thus, Caltha in- troloba, like other species of Caltha in the South- ern Hemisphere, belongs to sect. Psychrophila; Anemone crassifolia belongs to sect. Rivularid- ium; and Australian species of Ranunculus are related to South American species. Our conclusion is similar to that of Raven (248) who supposed that most high-mountain plants, including species of Anemone and Ranunculus, migrated to Australia and New Zealand from South America in the Late Pliocene or later. Raven suggested that a northern migratory route for plants into Australia through alesia was geologically impossible because the alpine flora of New Guinea is younger than t Australian one (334). Moreover, Melville (201) included the Ranunculaceae with a group of five families that invaded in Australia from the north. CONCLUSIONS The peculiarities of the role of the Ranuncula- ceae in the floras of regions and provinces world- wide reflect the peculiarities of origin, differentia- tion, and distribution of this family, including the relationships of tropical, temperate, mountain, and lowland floras, and including the relationships of the floras of the Northern and Southern hemi- spheres. According to paleobotanical literature (22, 60— 63, 93, 253-255), there are no fossil remnants of the Ranunculaceae in the Cretaceous. The ear- liest such fossils, fruits of some species of Clematis and Ranunculus, are Oligocene and come from Eurasia (e.g., England, Ukraine, the Urals). Ra- nunculaceae are represented in Miocene deposits by remnants of few species of Clematis, Ranun- culus, and Thalictrum. Pliocene ranunculaceous remnants belong to Aquilegia, Anemone, Clema- is, Ranunculus, and Thalictrum, about 40 tem- perate species altogether. They were found in many places within the vast territories of Eurasia, North America, and South America. These paleobotanical phenomena reflect the considerable differentiation of the Ranunculaceae and their radiation throughout the world durin the Neogene. The sharp increase of the develop- ment and dispersion of the Ranunculaceae was associated with the Upper Eocene general fall of temperature and replacement of tropical and sub- tropical floras with temperate ones across Eurasia and North America (78, 229, 307). 1040 Annals of the Missouri Botanical Garden There are two different opinions about the origin of the Ranunculaceae. Scharfetter (263) placed the origin within the Early Tertiary tropical flora, while Popov (235) claimed that the Ranunculaceae originated within the Neogene warm-temperate flora of Eurasia, similar to 50 other derivative angio- spermous familie e P with both these propositions and claim an Early aceous origin and differentiation of the Ranunculaceae. This is based partly on the peculiarities of the disjunctive areas of such genera as Caltha, Anemone, Clematis, Ranunculus, and Thalictrum. The origin and primary differentiation of the family must have taken place after the breakup of the supercontinent Pangaea (or one like it). Our data are consistent with the horizontal drift of the continents (138, 201, 250, and others). Development of the distinctive Holarctic and Holantarctic groups of Caltha (sects. Caltha and Psychrophila) occurred in temperate parts of Gondwana and Eurasia and seems likely to reflect the Middle Cretaceous differentiation of the north- ern and southern temperate floras. In this point we agree with Tolmachev (310) and Moore (211) who considered Caltha as one of the most ancient tem- perate Angiosperm genera The above-mentioned Anemone, Clematis, Ra- nunculus, and Thalictrum are temperate genera that occur fairly continuously throughout the mon- tane Palaeotropics and Neotropics and suggest the routes by which their migrations could have taken place. Notably, Anemone rivularis and Clematis ranunculoides with archaic morphological features are tropical-mountain forest elements of the flora of Southeastern Asia. Boughey (27) regarded the mountain forest flora in Africa and Asia as very old and maintained that its survival to the present as an insular flora scattered discontinuously over huge land masses implies a connection with con- tinental drift, land-bridges, and long periods of time. Our analysis showed that the majority of species of all genera occur in mountains and that, more- over, species of more than half of the genera, including all endemics, are restricted chiefly to mountain locations. Moreover, the most numerous groups of species of large genera such as Aconitum, Delphinium, Anemone, Clematis, Ranunculus, and Thalictrum are distributed mainly in moun- tains. Our data confirm Rau (243) who considered the Ranunculaceae to be an important member of the high-mountain ecosystems and is the basis for supposing its origin in mountain locations. Within temperate montane floras of the tem- perate regions the Ranunculaceae take fourth to seventh place, while in tropical montane habitats, the Ranunculaceae fall to 15th-17th place (70, 140) Comparison of the ranunculaceous representa- tives in the modern floras of the Northern and Southern hemispheres (the former contains 51 gen- era and about 2,200 species of all 14 tribes, the latter is home to 11 genera and about 250 species of 5 tribes) and comparison of their endemic genera (17 genera of 10 tribes vs. 4 genera of 2 tribes, respectively) indicates that primary differentiation of the Ranunculaceae took place in the Northern Hemisphere. From our geographical analysis together with data on comparative morphology, we propose that the ancestors of the tribes Cimicifugeae, Anemo- neae, Clematideae, Aquilegieae, Asteropyreae, and Kingdonieae initially developed within the ancient floras of eastern Asia, while the tribes Coptideae (at least Xanthorhiza) and Hydrastideae were formed in North America. It was impossible to dide the place of the development of the ances- s of the tribes Trollieae, Helleboreae, Delphi- nieae, Isopyreae, Ranunculeae, and Thalictreae, because some of their genera (e.g., Beesia, Cal- athodes, Trollius, Aconitum, Eranthis, Aquilegia, Semiaquilegia, Urophysa, and Dichocarpum) originated in eastern Asia, while other genera (e.g., Helleborus, Nigella, Consolida, Leptopyrum, and Aconitella) differentiated in the Ancient Mediter- ranean Subkingdom or North America (Enemion and Anemonella). Some associated in their origin and distribution with the temperate palearctic flora Adonis, Trautvet- teria, Isopyrum, Paraquilegia, and Paropyrum). (Delphinium, Callianthemum, In conclusion, we regard the Ranunculaceae as an ancient temperate family that originated in Cre- taceous time within montane temperate floras of the Northern Hemisphere.

Miller: NEW WORLD SPECIES OF EHRETIA (BORAGINACEAE) ABSTRACT Ehretia is a pantropic M genus of about 50 species with centers of diversity in eastern Africa and tropical Asia. Although as many as 12 species of Ehretia have been recognized in the New World, field and herbarium studies suggest that the patterns of variation in the New World i recognized Ehretia anacua and E. tinifolia as distinct ed and have distinguished several species with serrate leaf margins. Field studies suggest that characters used to differentiate species with serrate leaf margins often var y within populations or on a single individual. Thus Ehretia latifolia i is treated in a broad sense, including all segregate leaves. species with serrate The largest genus of the subfamily Ehretioideae, Ehretia, contains about 50 species (Airy-Shaw » 1973) distributed tropically and subtropically in both hemispheres. The genus is primarily Old World in distribution with more species in Africa than in Asia; Baker & Wright (1905) recognized 23 Af- rican species, mostly in eastern Africa, Johnston (1951) recognized 12 species in eastern Asia, and perhaps several more occur in the Malay archi- pelago and Australia. The genus is poorly repre- sented in the New World where it ranges from The last complete treatment of the New World species was that of Miers (1869) who recognized eight species. An additional six species were published by various authors after his work. Standley (1924) recognized seven species in Mexico and one more in Costa Rica (Standley, 1938) based on relatively few collections of the species with serrate leaf mar- gins. With the great increase of collections avail- Texas to Panama and the Greater Antilles. able since Standley's work, initial studies suggested that the characters he used to separate the species were of questionable validity, and delimitation of the species became problematic. The present re- vision combines a study of herbarium specimens with extensive field study of the variation of leaf and indument characters to resolve these problems. The work is supplemented with surveys of leaf architecture and pollen morphology throughout the Ehretioideae to be published later; only results di- rectly relevant to the New World species of Ehretia are included n addition 1 to o problems with delimitation of species of Ehretia in the New World, there have been questions regarding definition of the genus. An additional aspect of this study was an exami- nation of generic limits in the arborescent genera of Ehretioideae. Selected species of Bourreria, Carmona, Rochefortia, Rotula, and Old World species of Ehretia were examined.

Linnaeus (1759) later validated the genus with the binomial Ehretia tinifolia. De Candolle (1845) significantly enlarged the concept of the genus by treating 58 species, many of which are now referred to the segregate genera Bourreria, Carmona, Rochefor- tia, and Rotula. De Candolle recognized four sec- tions within Ehretia. All of the species of his sect. Ehretia are still referred to the genus but his sect. Bourreria was a diverse group of species now as- signed to Bourreria and Ehretia. The two species that he treated in sect. Carmona have been con- sidered conspecific and treated as Carmona retusa (Vahl) Masamune (Thulin, 1987). His fourth sec- tion, sect. Xeroderma, was another diverse group containing species now distributed in Bourreria, Ehretia, Rochefortia, and Rotula. Several species of sects. Bourreria and Xeroderma have since been excluded from Boraginaceae (see excluded species). John Miers published a series of papers on the Boraginaceae shortly after De Candolle's work and treated Ehretia (Miers, 1869) in a more restricted se. Miers segregated the genus Rotula (as Rhabdia) and allied it with Khretia and Cortesia (a small genus endemic to saline areas in northern Argentina). Miers also sorted the species that most recent authors have included in Bourreria into Bourreria and Crematomia. Crematomia was characterized by having fruits with four pyrenes, each retaining an apical attachment to the stigma at maturity. Recent authors (Schulz, 1911; No- wicke, 1969; Gibson, 1970; Miller, 1988) have not accepted this as sufficient for generic recog- nition and have included these "Crematomia" species in Bourreria. Miers pointed out that Bour- reria was distinct in its fleshy calyx with five mar- ginally tomentose, valvate lobes; fleshy, rotate co- rollas; and fruits that at maturity divide into four angular Lied each with a ridged endocarp and spongiase mesoc Bentham & Hooker (1876) recognized three sections e Ehretia, one of which, Carmona, has been treated as a segregate genus by most recent authors (Johnston, 1951; Nowicke & Miller, in press). Johnston (1951) recognized their other two sections, Kuehretia and Bourrerioides, in his treat- ment of the eastern Asian species. Although John- ston devoted most of his research career to Bo- raginaceae, he published little on Ehretia or Bourreria. He did recognize Carmona and Rotula as distinct from Ehretia (Johnston, 1951). In his treatment of the Boraginaceae of the southern West Indies (Johnston, 1949) he also considered Bour- reria and Rochefortia as distinct from Ehretia. Hence, although Johnston never treated Ehretia, it appears that his generic concept was similar to that of most recent authors As currently defined, ilie Ehretioideae consist of eleven genera that segregate into four probably monophyletic groups, but the relationships among them remain obscure. Richardson (1976, 1977) separated Tiquilia from Coldenia and these two genera of prostrate plants with dry nutlets form a distinct lineage within the Ehretioideae. Lepido- cordia, including Antrophora (Miller & Nowicke, in prep.), is also quite distinct from any of the other genera of the Ehretioideae, and Johnston (1950) considered the genus intermediate between the Eh- The Argentinian endemic Cortesia and the Australian endemic Hal- retioideae and Heliotropioideae. gania comprise a questionable third group of shrubby plants of xeric regions with often trifid or unevenly toothed sclerophyllous leaves. Whether these two genera are closely related or simply share a similar appearance because of convergence in similar habitats is unclear. Halgania is unique in the Ehretioideae in its stamens connate around the style. The remaining genera of Ehretioideae, Bour- reria, Carmona, Ehretia, Pteleocarpa, Rochefor- tia, and Rotula, seem to form a rather close group. Of these only Pteleocarpa seems to stand apart in its unusual winged fruits. Although recent pollen studies (Nowicke & Miller, in prep.) supported recognition of Bourreria, Carmona, Rochefortia, and Rotula as distinct appear closely related and form a distinct group within the subfamily. (See Table 1 for comparison.) Thulin (1987) transferred five African species of Ehretia to Bourreria, a genus previously con- sidered to be restricted to the Neotropics. These species seem to form a monophyletic group distinct rom Ehretia, they still from Ehretia in their valvate calyces, campanulate to urceolate corollas, and ridged endocarps. Eh- retia is a more natural genus without these species, but they are probably distantly related to the New World species of Bourreria, which are character- ized by rotate corollas and pollen grains with thick- ened ridges on each side of the colpi (Nowicke & Miller, unpublished). The characteristics of the genera closely allied to Ehretia are compared in Table 1 and a key to the genera of the Ehretioideae is provided below. Although Johnston (1935) in cluded Saccellium in the Ehretioideae, recent pol- len studies (Nowicke & Miller, in prep.) indicate that it is more closely related to the genera of the Cordioideae where Tahktajan (1987) placed it. 1052 Annals of the Missouri Botanical Garden KEY TO THE GENERA OF THE EHRETIOIDEAE la.

These are Ehretia anacua (Teran & Berl.) I. M. Johnston (as E. elliptica DC.), E. latifolia DC., and E. tinifolia L. Miers (1869) adopted a very narrow species concept, recognizing seven species with entire leaf margins, where only two have been recognized by recent authors (Stand- ley, 1924; Nash & Moreno, 1981). Various au- thors described six New World species of Ehretia with serrate leaves between 1891 and 1938. Stand- ley (1924) recognized five species with serrate leaves in Mexico and an additional one from Costa Rica (Standley, 1938). They differed in leaf shape and indument, although field studies reveal these characters are extremely variable. The present study recognizes three species of Ehretia in the World. This differs from recent treatm by grouping all populations with distinctly serrate leaf margins as a single, variable species. This variation in leaf morphology of Ehretia latifolia is discussed in detail under that species.

MORPHOLOGY HABIT All species of Ehretia are trees or shrubs (Fig. 1). Although New World species are trees, E. an- acua is frequently multistemmed. Habit is much more variable among the O orld species, which range from trees, like E. acuminata fad desert shrubs, such as E. rigida (Thunb.) Druce. The genus Rotula differs from Ehretia in its arch- ing, flexuous branches associated with its rheophy- tic habitat. The trunk of Æ. latifolia is usually uted, at least on mature plants (Fig. 2 LEAVES All species of Ehretia have simple, alternate, nearly lanceolate to nearly round leaves. A few Old World species are extreme, for example Eh- retia saligna R. Br. of Australia has elongate, straplike leaves. Leaf shape is variable within species, a single individual often showing a signif- icant diversity of leaf shapes on a single branch (see E. latifolia). Ehretia tinifolia and E. anacua have entire- Volume 76, Number 4 1989 Miller 1053 New World Ehretia NR. o mm AT NT Ficures 1, 2. Ha rown. e trees are often left as sh margined leaves. In some specimens of Ehretia anacua, however, a few leaves exhibit short teeth along the margin. Ehretia latifolia is unique among the New World species in its evenly serrate leaf margins. Only rarely are the teeth short and un- even. Leaf architecture can be valuable in delimitation of higher taxa (Hickey & Wolfe, 1975; Lorence, 1985; Levin, 1986a, b, c) and has been used within 77). Leaves of 36 species of 10 genera of i dada d for leaf architectural features. Eleven species of Ehretia were selected, including the three New World species. Leaves were removed from her- barium collections, cleared, stained, and mounted according to methods of Dilcher (1974), and ar- chitectural features were analyzed following the system of Hickey (1973, 1977, 1979). A complete survey of the genera of the Ehretioideae will be genera (Rury & Dickison, 1 published separately, but results are reported here for the New World species of Ehretia and several other taxa for comparison. Voucher specimens for the leaves examined are cited in the figure captions. Leaves of Ehretia appear to be primitively bro- chidodromous, this being the condition in nearly all of the species, and in the closely related genera Bourreria, Rochefortia, and Rotula. Craspedod- romous venation is restricted to the few species with serrate leaf margins. Of the New World species, E. tinifolia has brochidodromous venation (Fig. 4). Ehretia latifolia is the only New World species consistently with craspedodromous venation (Fig. 3). Although this might appear to be a conservative character, it is variable in E. anacua, which gen- bit of Ehretia latifolia. —1.

Note the dense hited trunk of the same near Guelatao, ud erally has brochidodromous venation (Fig. 7) but occasional individuals and leaves on juvenile shoots ave serrate margins and semicraspedodromous venation (Fig. 6). Even in E. acuminata, an World species with serrate leaves (Fig. 5), leaves are brochidodromous with veins that arise second- arily from outer loops beyond the secondaries and extend into the teeth. The patterns of tertiary and higher-order ve- nation vary only slightly among the species of Eh- retia. Generally, five or six orders are visible in most species. Ehretia anacua (Fig. 8) and E. tin- ifolia have randomly reticulate tertiary veins that anastomose and form a weak, composite interse- condary vein. The higher orders of venation vary from random to orthogonal reticulate. The ultimate marginal venation is looped in both of these species. Ehretia latifolia (Fig. 9) and E. acuminata (Fig. 10) have randomly reticulate to weakly percurrent tertiary veins. Intersecondary veins are weak and restricted to the apical portion of the leaf, or are completely absent. Ultimate marginal venation is incomplete in E. latifolia but looped in E. acu- minata The New World species of Ehretia are essen- tially evergreen. Ehretia anacua is partly decid- uous only at the northern extreme of its range in Texas. Ehretia latifolia appears to produce most of its leaves during the onset of spring rains and hold them for about two years. Only in the pop- ulation near Monte Alban, Oaxaca, in Mexico did ed all of its leaves during the dry season. New leaves were emerging even as the last few old leaves dropped.

As the leaf reaches senes- Standley (1924) differentiated New World species of Ehretia using density and thickness of hairs and presence or absence of glandular hairs. Field observations indicate that neither of these are significant in the sense that Standley used them. The widely scattered geographic pattern of plants with glandular hairs is not indicative of a mono- phyletic group, but rather probably a character that is expressed only rarely. Collections of Ehretia anacua and E. latifolia show considerable variability in leaf indument, much of which can be explained as a temporal phenom- enon. Young leaves of E. latifolia are densely and softly pubescent. Expansion of the leaf blade de- creases the density of hairs, and young, fully ex- panded leaves are less densely pubescent with long- shafted, simple hairs from a multiple-celled, basal cystolith. During the life of an individual leaf, the majority of the brittle shafts of the hairs are often broken off and the leaf may appear nearly glabrous cence, the cells of the basal cystolith continue to expand and harden. The basal cystoliths with the remaining portions of the hair shafts often make up what appears to be a scabrous indument. Thus an individual leaf may pass through stages from velutinous, to sparsely pubescent, to nearly gla- brous, and finally to scabrous. e southern portion of the range of Ehretia latifolia the dry season is less severe. Here leaves are somewhat larger, and seldom do herbarium collections contain eaves old enough to have reached the last, seem- ingly scabrous, stage. These field observations sug- gest that indument is not a reliable character for the delimitation of segregate species from £. la- tifolia.

E. acuminata ( The inflorescences of Ehretia tinifolia and E. la- tifolia have a distinct central rachis and are ba- sically paniculate with cymose individual branches. Ehretia anacua has a short-pedunculate, cymose inflorescence without a central leader. This type of cymose inflorescence is widespread in the Eh- retioideae and Cordioideae and is probably the primitive character state in the two subfamilies. FLOWERS The floral morphologies of the New World species of Ehretia are quite similar. Ehretia anacua has hairs on the corolla that are not present in F. latifolia or E. tinifolia, but other differences are small. Floral features that vary among the New 2. The Old World species are quite different and vary in nu- merous floral characters, including features of the World species are compared in Table 2. ' calyx and size, color, and form of the corolla. The diversity of breeding systems in the Borag- inaceae is well documented (Bawa & Beach, 1981; Ganders, 1979; Vuilleumier, 1967) and second only to Rubiaceae in the number of distylous species. Ehretia has monomorphic, bisexual flowers with the stamens exserted and exceeding the style. This is the most common breeding system in the Eh- retioideae; the only genera that differ are Lepi- docordia (Miller & Nowicke, in prep.) and Ro- chefortia (Lefor, 1968), both dioecious. Corollas are small and white in the New World species and are visited by a wide variety of small generalistic Diptera, Hymenoptera, and Lepidoptera. The plants | observed of Ehretia latifolia were visited by many small insects, mostly dipterans. POLLEN Pollen is particularly useful in generic delimi- tation in the Boraginaceae (Avetissian, 1956; Now- CN TRU RETIN ORES PERE TOA RS: AS SA & "ur, a. D č ^ d M. cM APA AA ORE.

Three pseudocolpi or pseu- docolpoid depressions alternate with the colpi. The apertures have elongate colpi with a bridge of ek- texine over the endoaperture. The tectum is more or less complete and faintly rugulose, slightly gran- ular, or psilate. Ehretia is homogeneous and distinct from other genera of the Ehretioideae in its pollen morphology (Nowicke & Miller, in prep.). Evidence from pollen does not support earlier sectional divisions of the genus (see Bentham & Hooker, 1876; Johnston, FRUITS The fruits of Ehretia are drupaceous with a thin to leathery exocarp, fleshy to mucilaginous me- socarp, and bony endocarp. They vary from white, as in E. latifolia, through yellow and orange, as in E. anacua, to red, as in E. longiflora Champ. (Johnston, 1951). The calyx generally persists ba- sally but is not at all accrescent. Although the stigma is usually lost, the base of the style often persists at the apex of fruits. Fruit morphology has been important for generic delimitation in the Ehretioideae. Bourreria, Car- mona, Ehretia, Rochefortia, and Rotula have es- sentially drupaceous fruits, varying in the texture of the mesocarp, number of parts into which the endocarp divides at maturity, and surface sculp- turing of the endocarp. The mesocarp of these genera except for Bourreria is fleshy to mucilag- inous. That of Bourreria is spongiose, being fleshy only when fruits are immature, becoming somewhat fibrous with large open air pockets. The structure of endocarps was examined by Volume 76, Number 4 Miller 1057 New World Ehretia TABLE 2. Comparison of floral features of the New World species of Ehretia.

They were then examined with an Hitachi 5450 scanning electron microscope. Fruits of 54 species of ten genera of Ehretioideae were examined. Col- denia and Tiquilia stand apart in having fruits of four dry nutlets. The fruits of Halgania, Lepi- docordia, and Rotula all differ in having a thin- walled endocarp. Bourreria, Carmona, Ehretia, and Rochefortia, however, all have somewhat sim- ilar fruits. Fruits of Ehretia vary in the number of parts into which the endocarp divides. Of the species examined, Ehretia latifolia is the only species whose endocarp remains entire at maturity. Ehretia ac- uminata, E. anacua, E. dicksonii, and E. tinifolia have fruits with two separate two-seeded pyrenes at maturity. Ehretia amoena, E. coerula, E. cy- mosa, E. laevis, E. obtusifolia, and E. rigida have fruits with four separate single-seeded pyrenes. Of related genera, Carmona has an endocarp that remains entire. Rotula has a two-parted endocarp and Bourreria and Rochefortia have four-parted endocarps. The surfaces of the endocarps of Khretia species have distinct sculptural patterns. Two major types occur in Khretia, and several others turn up in related genera. Verrucose endocarps are found in Ehretia acuminata (Fig. 15), E. dicksonit, E. la- tifolia (Fig. 13), and F. tinifolia (Fig. 12). Ehretia dicksonii is unusual among these species in having an evenly puberulent endocarp with numerous short hairs on the outer surface. Areolate endocarps, with angular depressed areas, characterize most of the Old World species with four-parted endocarps, including E. rigida (Fig. 14). Ehretia anacua, of the New World (Fig. 11), also has an areolate endocarp but differs in being less regularly areolate and in ano dividing into two parts at maturity. Th of the most closely related genera re are quite different in sculpturing pattern. Carmona retusa has an entire endocarp with few, low, broad ridges but is otherwise nearly smooth (Fig. 16). Rochefortia has endocarps with broad, thick, rounded ridges as exemplified by R. spinosa (Jacq.) Urb. (Fig. 19 varying from erect, as in Fig. 18), to ee as in B. nemoralis (Gurke) Thulin (Fig. 17). Fruit structure suggests that KAretia consists of o two groups. One has one- or two-parted endocarps with a verrucose surface and is found in the New World and Asia. The second has four-parted en- docarps with an areolate surface and is widespread in the Old World. Ehretia anacua is the only New World species in the latter group but differs in having a two-parted endocarp. SYSTEMATIC TREATMENT Ehretia P. bae Civ. Nat.

Distribution. | Ehretia anacua occurs in southern Texas and northeastern Mexico from sea level to 1,300(-2,200) m in dry forests (Fig. 20). Collections from Guanajuato, Oaxaca, and Que- retaro are outside the natural range of the species and are not included in the distribution map. This common species was known as Ehretia elliptica DC. until Johnston (1924) discovered the older epithet published in Gaza Terán & Berlan- dier. The description of E. scabra indicates that it is synonymous although the brief citation of “cres- cit in Mexico" does not indicate a type collection. The names F. ciliata and E. exasperata are clearly synonymous; E. ciliata differs from E. anacua in no discernible characters, and the type of E. ex- asperata is merely a juvenile shoot with serrate- margined leaves. Likewise, the type of E. lancifolia does not differ significantly in any character from E. anacua. Although most type material for the names lacks adequate locality information, it seems likely that all were collected in northeastern Mexico or Texas, a region in which no other species of Ehretia occur. n addition to its distinct geographic range, £. anacua is easily distinguished from the other New World species of Ehretia by its scabrous upper leaf surface, cymose inflorescence, strigillose co- rola tube, and usually entire leaf margins. It is quite distinct in the genus with no apparent close relatives. Ehretia anacua is valued for its showy flowering display and its shade. The specific epithet is derived from the common name “anacua” (Nuevo León, 1060 Annals of the Missouri Botanical Garden CARIBBEAN AMERICA o 800 kms L 9 " EN ; ^N Ya o . d ^ ec Ct e : e ^ ug i N -* Í FiGURE 20.

Distribution. | Ehretia latifolia occurs from Volume 76, Number 4 1989 Miller 1063 New World Ehretia CARIBBEAN AMERICA o 800 kms — 4 ML m FIGURE 21. Distribution of Ehretia latifolia. Jalisco in western Mexico through Central America to Chiriqui Province in Panama in cloud forests and dry montane forests at (1,500-)1,800-2,300 m (Fig. 21). Ehretia latifolia exhibits extreme variability in leaf shape and indument, which has bred confusion. Standley (1924, 1938) recognized six species with serrate leaves in the New World. With the excep- tion of E. tehuacana, all were based on characters of leaf shape and indument. When Watson (1891) published E. mexicana, he made no mention of how it differed from Æ. latifolia. The types of the two are nearly identical, and Standley (1924) re- duced E. mexicana to synonymy. Smith (1893) published E. luxiana based on a collection from Guatemala with broader leaves that was almost glabrous abaxially and supposedly had larger flow- ers. The populations from the southern portion of the range do have slightly broader leaves that more often tend toward abaxial glabrousness, but there are many exceptions and there is no clear geo- graphic discontinuity. At the time that Robinson (1894) published E. cordifolia it appeared distinct in having cordate leaf bases. However, field studies (discussed below) indicate that this is not a valid character since it varies on single individuals as well as within populations. The problem with Ehretia viscosa, a species supposedly distinct in having glandular hairs, is slightly more complex. The few collections of it differ only in the possession of glandular hairs and in all other respects are identical to E. latifolia. Further, they come from localities scattered throughout the Mexican range of FE. latifolia. Glan- dular hairs thus appear to be an infrequently ex- pressed trait rather than a monophyletic group that should be recognized as a species. Standley (1924) differentiated Ehretia tehua- cana by its corollas about 10 mm long (supposedly more than 3 mm longer than the other species he recognized). None of the corollas on the type col- lection exceed 6 mm (Standley must have based his distinction on Greenman's original description) and are within the normal range of variation for E. latifolia. At the time that Standley (1938) de- scribed E. austinsmithii, it appeared to be geo- graphically disjunct with the nearest population to the north in Guatemala. As currently defined, F. latifolia has a relatively continuous distribution in Central America, being unknown only in Honduras. The Central American populations are quite uni- 1064 Annals of the Missouri Botanical Garden TABLE 3. Populations of Ehretia latifolia sampled for variation in leaf shape and indument.

FIELD STUDIES OF VARIATION OF LEAF MORPHOLOGY The numerous synonyms of Ehretia latifolia seem to have arisen via a paucity of collections and a failure to understand how leaf shape an indument vary on individual plants, within popu- lations, and between populations. Herbarium spec- imens are only limited samples of individual trees and seldom provide an adequate representation of variation of leaf morphology. In order to assess how leaf morphology varied on a single individual, within populations, between populations, and over the developmental life span of individual leaves, collections were made over the range of F. latifolia in Mexico. ome variation emerges during the ontogeny of an individual leaf (discussed earlier under leaf mor- phology) and a small portion correlates with ge- ography, but most variation appears random and often can be found within a single population. Two characters seem to vary geographically. Plants from Central America and part of adjacent Chiapas tend toward slightly broad, abaxially nearly glabrous leaves, while plants from populations fur- ther north have narrower, abaxially pubescent leaves. other collections from Central America have leaves puberulent below, and such However, leaves are found over a long geographic distance Trends of this sort occur in other woody Boraginaceae, for example, Cordia curassavica (Jacq.) Roemer & Schultes (Miller, 1985), and are perhaps a result of a more with no clear discontinuity. pronounced dry season than occurs to the north in parts of Mexico. In Cordia curassavica much of the variation disappears in plants raised in the greenhouse (Miller, 1985). he second geographically correlated variation is that plants from the Tehuacán Valley in Puebla, Mexico, have leaves with smaller than usual ser- rations on the margin. This extreme of variation is not even consistent within Puebla and is not considered worthy of taxonomic recognition. Most variation in leaf morphology appears ran- dom, varying in form and indument on individuals and within populations. Five leaves from five in- dividuals (in some cases five individuals could not e found) in each population from various parts of the distributional range in Mexico were measured for length, width, length / width ratio, broadest point (calculated as distance from broadest point of the leaf to the base divided by total leaf length), apical angle, and basal angle (Tables 3, 4). In addition the indument on the adaxial and abaxial leaf sur- faces was noted. The leaves selected were at least three nodes below the apex of the shoot to avoid immature leaves and never adjacent to a branch, as these are often quite different in form. Field studies reveal considerable variation in leaf shape on a single tree, with leaf bases often varying from acute to obtuse and sometimes even cordate Volume 76, Number 4 1989 Miller 1065 New World Ehretia TABLE 4. lower figures are standard deviations.

Shape of the leaf base was the character used to distinguish Ehretia cor- difolia, but examination of leaves from different branches of a single tree collected near Guelatao, Oaxaco, Mexico (Fig. 22) shows this character to vary on a single individual. The same type of vari- ation in shape of leaf apices often occurs on single individuals, as exemplified by leaves from different branches of an individual collected near Motozintla, Chiapas, Mexico (Fig. 23). Most of the Mexican populations examined were relatively constant in terms of leaf indument, al- though occasional plants were more or less pubes- cent than surrounding individuals. There did ap- however, pear to be, a significant amount of variation in leaf shape among individuals from a single population. Leaves from the "p wire at Monte Alban (Fig. 24) ranged from 1.5 to 3.2 in leaf length/width ratio and 45? angle. The sampled population near Ciudad Men- doza (Fig. 25) had leaf length/ width ratios of 1.7 to 3.4 and a range of 60? to 240? in basal angle. If this degree of variation can be found in a single to 100? eN apical population, leaf apex, blade, and base shape are not reliable characters for delimiting species. Mean values and standard deviation are given for characters of leaves from Mexican populations of Ehretia latifolia in Table 4. Leaf length/ width ratio, broadest point, apical angle, and basal angle appear to be the best measures of overall leaf shape.

Tree to 15(-25) m tall, the twigs essentially glabrous. Leaves persistent; petioles (3-)5-10(-14) mm long, glabrous canaliculate adaxially; leaf blades elliptic, (5-)6.5—12(-16.5) cm long, (2.5-)3-6(-8) cm wide, the apex obtuse to rounded, the base 1070 Annals of the Missouri Botanical Garden obtuse to acute, the margin entire, adaxially gla- brous and lustrous, abaxially glabrous, the lateral veins 6-7. Inflorescence terminal, paniculate, 7— 15 em long, the branches glabrous. Flowers bisex- ual, sessile or short-pedicellate; calyx campanulate, 1.5-2 mm long, the 5 lobes ovate, 1.5-2 mm long, 0.7-0.9 mm wide, glabrous externally, ciliate along the interior margin; corolla white, tubular-cam- panulate with 5 reflexed lobes, 4-4.6 mm long, glabrous on the exterior surface, the lobes widely oblong to oblong-ovate, 2.5-5 mm long, 1.3-1.7 mm wide, the tube 1.3-2.1 mm long; stamens 5, the filaments flattened, 3-4.5 mm long, the upper 2-3 mm free, glabrous, the anthers ellipsoid, 1— 1.3 mm long; ovary ovoid to broadly ovoid, 1-1.2 mm long, 1 mm broad; style 2-3.4 mm long, divided for 0.5-0.7 mm, the stigmas truncate. Fruits drupaceous, yellow-orange, glabrous, broad- ly ellipsoid, 5-7 mm long, 4-6 mm broad, the endocarp dividing into 2, 2-locular pyrenes, these ridged-reticulate on the outer surface. Distribution. | Ehretia tinifolia occurs from southeastern Mexico to Honduras and on Cuba, Hispaniola, Jamaica, and the Cayman Islands in lowland, moist to wet forests from sea level to 600(-1,500) m (Fig. 26). Collections cited from Guerrero, Michoacán, Nayarit, San Luis Potosi, and Sinaloa are not included in the distribution map as they are presumed to be out of the natural range of the species and are probably from culti- vated plants. Ehretia tinifolia is distinguished from the other New World species by its glabrous, lustrous, entire- margined leaves and elongate, paniculate inflores- cence. It is widely cultivated, even outside of its natural range for its attractive flowering and fruit- ing display and as a shade tree. The two species described by Miers, Ehretia longifolia and E. sulcata, are both clearly syn- onymous from Miers's description and their West Indian distributions. Unfortunately, Miers cited specimens with little information and these collec- tions remain difficult to identify. For this reason, these names have not been lectotypified, and syn- types are cited here. Representativ e spec imens examined. MEXICO.

EXCLUDED SPECIES The majority of names published in Ehretia for the Neotropics are now considered synonyms of Bourreria and Rochefortia. In the following list, types have been examined when possible, but many of the names can be excluded from Ehretia based on the published descriptions. In placing the names I have relied heavily on the revisions of Bourreria (Miers, 1869; Schulz, 1911) and Rochefortia (Le- for, 1968) supplemented with notes from John- ston's extensive series of papers on the Boragi- naceae. When FEhretia names are assigned to species of Bourreria, they should be considered cautiously as the best name available from the literature since Bourreria is probably the most nomenclaturally confused genus of Ehretioideae.

León & Alain (1957) listed Ehretia spinifex Griseb. as a synonym of Bourreria divaricata but made no mention of the other names.

ABSTRACT Study of neotropical Euphorbiaceae for various floristic and taxonomic projects has uncovered several novelties. New taxa pr Colombia, Tragia ik ue e Peru, and the genus the border of Panama and Color oposed in this paper are Dalechampia liesneri from souther Tacarcuna, including the thr bia, 7. amanoifolia from Peru, an ela, — S tomentosa from ree new speci . gentryi, from achirensis from ud. In addition it n Venezue is shown that Caryode Eon ee) irense Muell. Arg. is the correct name for ihe plant hitherto known as C. grandifolium (Muell. Arg.) Pax The Euphorbiaceae, one of the largest families in the Neotropics, remains one of the least well understood. The largest genera, Acalypha, Cro- ton, Euphorbia, and Phyllanthus, have not been critically revised in this century, and only a handful of other, smaller genera have been the subject of modern study. Even at the most basic descriptive level, a great deal of work remains to be done, and the mere discovery of a new species can often lead to much insight into the taxonomy of its congeners. Such is the case with the collection of taxa proposed here, which result from study preparatory to the Flora of the Venezuelan Guayana (J. Steyermark & collaborators, in prep.), Checklist of the Flora of Chocó Province, Colombia (A. Gentry & E. Forero, in prep.), or from serendipitous discovery in the herbarium. Caryodendron janeirense Muell. Arg. in C. Mart., Fl. Bras. 11(2): 707. 1874. Centro- discus grandifolius Muell. Arg. in C. Mart., Fl. Bras. 11(2): 327. 1874, nom. inval.

Mueller published the name Centrodiscus gran- difolius with description and citation of type. Be- fore this went to press however, he added as a separate item on a different page "Addenda and Corrigenda” in which he pointed out that his Cen- trodiscus grandifolius belongs to Karsten's genus Caryodendron and that it differs from the only species, Caryodendron orinocense Karsten, by, among other things, having smaller leaves. Ap- parently thinking that the epithet grandifolium would be inappropriate in Caryodendron, he as- signed the new plant the name Caryodendron ja- neirense, which is the correct name for the species. Centrodiscus grandifolius was not published be- fore Caryodendron janeirense, pp. 273-754 of Volume 11, Part 2, appearing together on May 1, 1874 (Stafleu & Cowan, 1981: 333-337). Mueller was merely making a last-minute correction to text already too far along in press to be changed in- ternally. It is therefore clear that the name Cen- trodiscus grandifolius Muell. Arg. was not ac- cepted by its author when published and therefore is invalid according to Article 34.1 of the /nter- national Code of Botanical Nomenclature (Greu- ter, 1988). The combination of Pax based on that name is nomenclaturally superfluous. For the same reason, the generic name Caryodendron Muell. Arg., published simultaneously with Caryodendron grandifolius Muell. Arg. and likewise not acc ee by its author when published, is also invali I am inde bte d to Dr. drawings were 1 W.

Inflorescences bisexual, widely spaced, compact, the peduncle slender, densely puberulent, 1 -4 cm long. Staminate flowers distal, up to 8 present, the pedicels 2-5 mm long; bracts lanceolate, brown puberulent, acute, 2-4 mm long; buds fusiform, acute; sepals 5, ca. 2 mm long, membranous, ovate, acute, sparsely hirtellous, re- flexed at anthesis; stamens 8-10, the filaments united nearly their entire length to form a slender tube 4-5 mm long, the anthers free at apex, the tube penicillate toward apex. Pistillate flowers 3, or 2 sometimes aborting before maturity, prox- imal, subsessile at anthesis, the pedicel densely puberulous-hirtellous, greatly elongating in fruit (to 5 cm); sepals 6, linear-lanceolate, 2.8-3.2 mm long, acute, sparsely short-puberulent, the base thickened, the young fruit densely short-pilose; style slender, elongate, to 15 mm long, 0.2-0.3 mm thick, densely puberulent toward the base, other- wise glabrous. Capsule smooth, 3-lobed, short-pu- berulent, not seen entire, apparently 6—7 mm diam.; seeds ovoid to subglobose, smooth, ca. 4 mm diam., brown. The pantropical genus Dalechampia contains over 100 principally neotropical species. Numer- ous recent discoveries (Armbruster, 1984, 1988, 1989; Huft, 1984; Webster, 1967, 1988; Web- ster & Armbruster, 1979, 1982), many of them of taxonomic and phylogenetic importance, attest to the need for the critical study this genus is now receiving at the hands of Dr. Grady L. Webster and Dr. W. Scott Armbruster. Dalechampia liesneri did to sect. Rho- palostylis Pax & K. , the most primitive section of the genus, which oni is restricted to the northern and western Amazonian basin. Only four species have previously been described from this group: D. micrantha Poeppig from western Brazil and eastern Peru, D. parvibracteata Lanj. from the Guianas, D. olympiana Kuhlm. Ro- drigues from northern Brazil, and the recently de- scribed D. attenuistylus Armbruster from southern Venezuela (Armbruster, 1989). The genus Mega- lostylis S. Moore, whose only species, M. poep- pigii S. Moore, appears to be based on an isotype of D. micrantha, is synonymous with sect. Rho- palostylis. Section Rhopalostylis is characterized by ab- sence of the showy white, pinkish, purplish, or green bracts that are so characteristic of the rest of the genus; absence of resiniferous glands in the inflorescences; and larger, usually basally swollen, styles. Dalechampia liesneri is distinctive in its few-flowered, long-pedunculate, inflorescences and long, thin styles that are not at all swollen toward the base. Dr. Armbruster (pers. comm.), who is preparing a revision of this group, has discovered an additional population of this species near San e Cataniapo (ca. of Puerto Ayacucho) in southern Venezuela, and he reports that it is probably not uncommon in that region. It is a pleasure to name this species after Ronald Liesner of the Missouri Botanical Garden who has collected extensively in Venezuela during the past decade and has been responsible for many discov- eries and additions to our knowledge of the flora of that country.

Leaves alternate, short-petiolate; stipules obsolete; petioles 0.5-2.5 cm long, stout, densely hirsutulous to glabrate; blades chartaceous to subcoriaceous, broadly obovate-elliptic, 10-23 cm long, 7-12 cm wide, 1.5-2.8 times as long as wide, densely brown tomentose to glabrate below, moderately pilose to glabrate above, the apex rounded, obtuse, or short- acuminate, the base rounded, obtuse, or broadly cuneate, the margins entire to obscurely crenate- undulate; midrib prominent below, the secondary nerves 14-26 on a side, parallel, arching somewhat toward the margin of the blade, prominent below, light-colored above, neither raised nor impressed, the tertiary veins connecting the secondaries at right angles, regularly spaced, prominulous below. Inflorescences numerous, lateral, below current leaves, RE of clustered M 2-4 cm long, t ly brown tomentose when young, becoming densely puberulent at maturity. Stami- nate flowers 1-3 in sessile or subsessile glomerules, the buds globose, 0.7-1.1 mm diam. Pistillate flowers not seen, sessile or short-pedicellate; calyx persistent on young fruits, tomentose outside, the lobes 1-1.5 mm long, deltate, ca. 25 the length of the calyx; young fruits densely brown tomentose, pyriform, the styles 3, ca. 1 mm long, strongly ecurved, united at base, glabrous or with a few scattered. hairs. Capsules ellipsoid-obovoid, ob- scurely trigonous, glabrous, smooth, 11-16 mm the styles persistent, minute, long, 6-9 mm diam., the columella with broad papery wings, not per- sistent. This very distinctive species is easily distin- guished from the four to six other species of Rich- eria by the densely tomentose lower leaf surfaces on many specimens and by the short, compact, highly branched inflorescences. The prominent midrib and secondary veins are also distinctive. The widespread R. racemosa (Poeppig) Pax & Hoffm. has staminate spikes longer than the leaves rather than the short, compact, clustered panicles that are characteristic of R. tomentosa, and the cymules are distinctly pedunculate and two- or three-flowered. Two other South American species, R. grandis Vahl and R. obovata (Muell. Arg.) Pax & K. Hoffm., have longer and less compact inflo- rescences than R. tomentosa and are completely glabrous; their leaf margins are prominently cre- nate-undulate (vs. entire or obscurely crenate-un- dulate). The recently described R. dressleri Web- ster (Ann. Missouri Bot. Gard. 75: 1094. 1988), from Panama and apparently Costa Rica, is dis- tinctive in its two-carpellate ovaries and fruits.

Pistillate flowers pedicellate, the pedicel elongating in fruit; perianth as in the pistillate flowers (sepals and petals only 3 in 7. tachirensis, in which staminate flowers are unknown), persistent on the mature fruit; carpel 3-locular, the locules uniovulate; styles 3, divided at apex. Fruits capsular, the thin outer wall sep- arating from the thicker inner wall at dehiscence; seeds apparently ovoid-lenticular, smooth or per- haps sculptured, often misshapen, rarely seen ma- ture. This genus of small to medium-sized trees seems Volume 76, Number 4 Huft 1081 South American Euphorbiaceae quite unlike any other Euphorbiaceae in the Neo- tropics, and I have been unable to match it with any Old World representatives of the family. The collections available have mature capsules and young fruits that retain the pistillate calyx and corolla. Only one specimen (T. gentryi, Gentry et al. 16901 MO), however, has staminate flowers, and these are partially embedded in mounting glue. Additional material of 7. gentryi containing abun- dant staminate flowers was collected but has ap- parently been lost or misplaced (A. Gentry, pers. comm.). Since characters of the staminate flowers are of great importance in generic delimitation in the Euphorbiaceae, I have been reluctant for some time to describe this new genus, pending recovery or re-collection of staminate material. However, partial dissection of the available staminate flowers revealed five free stamens and a well-developed staminode; these features along with the glomerate, axillary inflorescences, presence of petals, and im- bricate calyx mark this as a previously undescribed genus. Only recently have collections of two additional species of this remarkable genus come to light, and, even though staminate material is lacking in these species, all three species are described to- gether in the hopes of stimulating further explo- ration. In addition to the characters already men- tioned, the three species of Tacarcuna are held together by the combination of ovate-lanceolate or obovate-lanceolate leaves with very short, stout petioles; the sepals and often the petals more or less densely puberulous centrally on the outer sur- face, and with distinctly hyaline margins; deeply lobed capsules somewhat depressed at the apex; and a network of low ridges on the mature capsules, especially prominent in 7. gentryi, less so in T. amanoifolia, and largely obscured by the veluti- nous indument in 7. tachirensis.

These features along with a sometimes lighter color along the margins impart to the leaves an appearance strikingly similar to that of 4manoa guianensis Aublet, a widespread euphorbiaceous tree of the lowland forests of north- ern South America and southern Central America. Its short mature pedicels give the fruiting branch a more congested appearance than in T. gentryi. Additional specimen examined. PERU. MAYNAS: Dtto.

This species is known only from a single collec- tion on steep forested slopes above 1,200 m. Only post-mature (i.e., already dehisced) capsules are available. The capsules are distinctive in their densely velutinous indument. The leaves are similar to those of 7. amanoifolia in their thicker texture and lustrous surface, but are more characteristi- cally lanceolate-ovate rather than lanceolate-ob- ovate, and have more closely spaced and more numerous secondary veins; the tips are acute (rare- ly short-acuminate) rather than prominently cus- pidate-acuminate as in T. amanoifolia. 1084 Annals of the Missouri Botanical Garden Volume 76, Number 4 1989 Huft South American Euphorbiaceae 1085 Tragia rubiginosa Huft, sp. nov.

This unusual species would key to sect. Bia (Klotzsch) Muell. Arg. in the treatment of Pax & Hoffmann (1919) on the basis of its five stamens and the presence of disk glands in the staminate flowers, but it seems hardly related to the other species of that section, which are characterized by their usually deeply cordate leaves (except 7. les- sertiana (Baillon) Muell. Arg.) and especially their robust, bipartite inflorescences with one branch staminate and the other pistillate. Were it not for the presence of the disk glands, however, Tragia rubiginosa might seem almost at home in the Cu- ban genus Platygyne Mercier, which Pax & Hoff- mann distinguished from Tragia by unisexual (vs. androgynous) inflorescences, 5-15 (vs. 2-50 usu- ally near the lower end of the range) stamens, globose hairy receptacles, free filaments, absence of a disk, and wide styles emarginate at the apex. Liogier (1971: 132, 133) was spurred by his study of the Hispaniolan species Tragia biflora Urban, which closely resembles Platygyne, to in- vestigate the relationship between Tragia and Pla- tygyne. He found that the generic characters are intermixed in some species referred to Platygyne, and particularly in 7. biflora, which has a globose, glabrous receptacle with 10-20 stamens and wide, but not emarginate, styles. His conclusion that Platygyne cannot be kept separate from 7ragia is bolstered by the existence of 7. rubiginosa, which has the five stamens and monoecious inflo- rescences typical of Platygyne but has a disk, flat glabrous receptacle, and nonemarginate styles. The inflorescences of T. rubiginosa are reminiscent of those of T. biflora, which likewise are monoecious, axillary, and somewhat reflexed, although consid- erably shorter and with a less pronounced peduncle. The leaves also seem similar but are longer, nar- rower, and less coarsely crenate in 7. rubiginosa. The specific epithet refers to the red-brown color of the flowers. LITERATURE CITED ARMBRUSTER, W.

MORPHOLOGY AND TAXONOMIC CHARACTERS Ampelocera species are small to large trees often with slender, channeled buttresses and smooth gray bark. The wood is light brown to cream-colored and hard. LEAVES The leaves of all species are pinnately veined except for those of Ampelocera hottlei, which are trinerved at the base. The texture of most leaves is coriaceous, but 4. cubensis and A. macphersonii have chartaceous leaves. The leaves of Ampeloc- era are glabrous except for those of 4. cubensis, which are sometimes softly puberulent beneath. Young leaves in most species are often many times larger than those on fertile branches. Young leaves of A. hottlei and A. macrocarpa are distinctive for their bright blue metallic color. Nearly all leaves of Ampelocera are oblong to elliptic with characteristic oblique bases and atten- uate apices. Ampelocera cubensis, A. glabra, and A. ruizii often have obscurely and coarsely dentate leaves. Petioles are usually thick and have a red flaky epidermis. INFLORESCENCES Ampelocera inflorescences are axillary, some- times simple, usually compound dichasia or rarely are panicles of compound dichasia. In A. glabra the rachises are so short that the inflorescences appear fasciculate. The longest and most densely flowered inflorescences in the genus with up to 56 flowers are found in 4. longissima. Inflorescences have perfect flowers and functionally staminate flowers, the latter being found lower on the inflo- rescence axis. FLOWERS Ampelocera flowers are small, cream-colored, yellow, or green and offer a limited number o characters. All dimensions provided in the descrip- tions are based on dried material. The perianth consists of a sepalar cup with four or five usually sparsely puberulent lobes. The lobes in 4. cubensis are villous. Stamen number varies from 4 to 16 with the staminate flowers often having fewer stamens (4— 8) than the perfect flowers. Two kinds of filaments are found in the genus: relatively thick filaments expanded near the base and drying flat characterize A. edentula and 4. macrocarpa, and relatively long, thin filaments that twist upon drying char- acterize the other seven species. The anther con- nective is extended beyond the thecae to form a strigose apicule. In the species with the short, broad filaments, the connective extension is very pro- nounced, while in those with long, thin filaments, the extension is smaller. The ovary in Ampelocera is puberulent and oblong to globose. The two style branches are free to the base in most species, but in 4. cubensis and A. ruizii they are united in the lower one-fourth. Staminate flowers often have cylindrical, ribbed pistillodes with the same vestiture as the ovaries in the perfect flowers. Size and shape of the drupaceous fruits of each species of Ampelocera are quite distinctive. Gen- erally the fruits of Ampelocera are yellow, asym- metrical, and transversely obovoid or ellipsoid; they vary from 0.6 to 2.2 cm long. The fruits may be glabrous (4. glabra, A. longissima), sparsely pu- berulent (4. edentula, 4. macrocarpa), densely pubescent (4. macphersonii), or densely pilose (A. rulzil). usual in the genus, are symmetrically oblong and velutinous with longitudinal striations. Ampelocera Ampelocera hottlei fruits, the most un- macrocarpa typically has pyriform fruits with an unusually thick endocarp. USES The wood of Ampelocera is hard and is used for firewood and lumber. In the Pichis Valley of Peru, the astringent bark of 4. edentula is used by the Campa Indians to tattoo skin. The bark is wetted and then bound around the arm, where it ulcerates the skin and causes a painful eruption. A coloring agent is then applied to the ulceration and scar tissue forms (A. Gentry, pers. comm.). SYSTEMATIC TREATMENT Ampelocera Klotzsch, Linnaea 20: 541. 1847. TYPE SPECIES: Ampelocera ruizii Klotzsch. ur ag Milbr. ex Baehni, e Field Mus. Nat. Hist., Bot.

Ampelocera cubensis is closely related to A. gla- bra from central coastal and southeastern Brazil and 4. ruizii from Amazonian Brazil, Peru, and Bolivia. It differs from 4. glabra by having smaller fruits and less prominently dentate leaves and dif- fers from 4. ruizii by having shorter inflorescences with 2-5 (vs. 8-23) flowers and by having sepals 1.5 (vs. 2-2.5) mm long. Morton (1958) described Ampelocera pubes- cens, distinguishing his new species from 4. cu- bensis by the vestiture of the lower leaf surface and the length of the stipules (4.5-6 mm in 4. pubescens vs. 3 mm in A. cubensis). | can find no other characters to corroborate the recognition of two taxa, and, in fact, vestiture of material annotated as 4. pubescens by Morton, including the type (Jack 6036), ranges from densely to sparsely pilose. 3.

This species is most closely related to A. macrocarpa from which it differs in having generally oblong fruits and a thin endocarp (vs. globose fruits and a thick endocarp). In his description of Ampelocera latifolia, Ducke (1943) stated that his new species might be just an upper-Amazonian variant of 4. edentula. The fruit on the type of 4. latifolia is distinctly oblong while that on the type of 4. edentula is smaller only a difference in fruit maturity, and since I could find no other consistently correlated char- acters, A. latifolia is placed into synonymy with A. edentula. Although Ampelocera edentula occurs through- out a broad geographic area in the Amazon Basin, it is poorly represented in herbaria, and conse- quently, its morphological variation is difficult to assess. branches, eaves are generally shorter on fertile 12-20 cm long, while sterile branches have leaves up to 30 cm long. Some collections from Peru and Bolivia (Schunke 4395, Woyt- kowski 7307 (Perú: Dept. San Martin); Krukoff 10727 (Bolivia: La Paz)) have leaves up to 35 cm on fertile branches. These populati liffer further from typical Brazilian 4. edentula in have shorter petioles, more oblique leaf bases, and more pubes- cent fruits. A sterile specimen from Peru (Dept. Loreto: Prov. Requena, Jenaro Herrera, Rio Uca- yali, 73°45'W, 4%55'S, 22 Feb. 1987, Gentry et al. 56289 (MO)) is unusual in having sparsely pubescent stems, petioles, and the lower surface of the primary and secondary veins. As more spec- imens become available, the variation presently included in 4. edentula may warrant recognition of other taxa. 4. Ampelocera glabra Kuhlm., Arch. Jard. Bot.

The leaves of this species are bright metallic blue when young and have strongly oblique bases. On saplings and young branches the leaves are extremely long and narrow (22-38 cm long). Ampelocera macrocarpa appears to be most closely related to 4. edentula by virtue of the characters given in the key. 8. Ampelocera macphersonii Todzia, sp. nov. TYPE. Panama.

Ampelocera macphersonii is distinctive in hav- ing entire leaves and small, orange, strongly asym- metrical, transversely obovoid fruits. By virtue of its 16 stamens it is allied to 4. pubescens, A. glabra, and A. ruizii. It differs from A. pubescens by having glabrous leaves and racemose (not glo- merulate) inflorescences, and from both 4. glabra and A. ruizii by having entire (not dentate) leaves and larger fruits. Vegetatively A. macphersonit resembles 4. longissima but can be separated eas- ily by the characters provided in the key. The occurrence of A. macphersonii in deciduous and semievergreen forests is unusual for the genus. This species is named in honor of Dr. Gordon McPherson whose collecting efforts in Panama have yielded many new and interesting plants. 9. Ampelocera ruizii Klotzsch, Linnaea 20: 541. 1847. TYPE.

Ampelocera ruizii is distinguished from 4. gla- bra by having smaller fruits and longer inflores- cences. They are similar in having dentate, gla- brous leaves and transversely ellipsoid, asymmetrical ruits. Baehni (1937) separated Ampelocera from Pla- gioceltis and the other Peruvian genera of the maceae on the basis of the former having twice many stamens as the latter. The isotype of Plagioceltis dichotoma at F, however, has a great- er number of stamens than perianth parts. Since stamen number is not mentioned in the Plagioceltis description, Baehni’s misplacement of the genus in the Flora of Peru key alongside genera possessing equal numbers of stamens and perianth segments is probably due to Mildbraed's inadequate notes (Gentry, 1983). As mentioned under taxonomic history, the similarity of the unnumbered Ruiz & Pavón type specimen of Plagioceltis dichotoma and the type of Ampelocera ruizii is the most likely because both originated from the same collection.

The pollen grains differ in size for all the five heterostylous species of Nivenia there are statistically significant size The genera Nivenia (nine species), Klattia (three species), and Witsenia (one species) comprise a natural alliance of Iridaceae, restricted in distri- bution to the southwestern Cape region of southern Africa. Uniting the genera are the following spe- cialized characters: a shrubby evergreen habit; a woody rootstock and aerial stems both having ap- preciable secondary growth; nonfugacious flowers with a well-developed perianth tube and bearing septal nectaries; tangentially compressed seeds; and a specialized leaf anatomy with submarginal scle- renchyma and girders produced by the extension to the epidermis of the sclerenchyma surrounding some of the vascular bundles (Goldblatt, in prep.; Goldblatt & Bernhardt, in press; Manning & Gold- blatt, in prep.; Rudall & Burns, 1989). This study of the pollen morphology of the three genera was undertaken in conjunction with a broad- ly based investigation of their systematics and re- productive biology, the latter focusing particularly on the heterostylous condition in five species of Nivenia. 'These distylous species are made up of populations of plants with either long styles and short stamens or short styles and long stamens. In many plants heterostyly is often associated with pollen dimorphism (Ganders, 1979; Richards, 1986) and this phenomenon has been considered in our examination of exine structure. The homostylous Klattia and Witsenia were included in our study for the sake of completeness. Klattia and Witsenia are probably bird pollinated (Rebelo, 1988; Gold- blatt, in prep.) in contrast to species of Nivenia which are pollinated by long-tongued insects, either anthophorid bees or nemastrinid flies (Goldblatt & Bernhardt, in press). Any differences in the pollen of the three genera may be significant in light of the differences in their pollination biology. MATERIALS AND METHODS Pollen taken from herbarium specimens of 11 species (Table 1) was treated in one of two ways. For examination of exine sculpturing alone, un- treated grains were glued on aluminum stubs an sputter coated with gold. For examination of whole grains, unacetolyzed pollen was rehydrated by warming in 10% KOH for ca. 10 minutes, then dehydrated in ethanol, rinsed twice in 50% acetone !

(listed in Table 3), where nine or ten grains in three or four individuals per style morph were measured (Table 3 OBSERVATIONS Grains of all species of all three genera are more or less spherical (Figs. 1-6), ranging from near prolate to near oblate depending on the species (Table 2). The monosulcate grains have a promi- nent elliptic to oblong sulcus (Figs. 2, 5, 6); are tectate-perforate in Witsenia with a micro- reticulate tectum (Figs. 4-6, 9, 10) and semitectate with a reticulate tectum in Nivenia and Klattia (Figs. 1-3, 7, 8). The floors of the lumina in all the species are granulate (e.g., Fig. 7). The muri are smooth in Klattia (Fig. 8) but minutely gran- ulate in /Vivenia and Witsenia (e.g., Figs. 7, 9, 10). In N. binata and N. stenisiphon the sides of the muri are irregularly ridged (e.g., Fig. 7) (Table 2). In Nivenia the luminae range from about as wide as the muri (microreticulate), e.g., /V. cinna (Fig. 12), to about twice as wide (reticulate), or up to four times as wide in N. capitata (Fig. 11) Supratectal gemmae (ca. 4 um in diameter) are restricted to Witsenia (Figs. 5, 6) and are scattered more or less evenly across the surface. The exine sculpturing ends abruptly at the sulcus (Fig. 2) in Nivenia and Klattia, but in Witsenia the muri become disrupted into pilae and baculae (Fig. 10) along the sulcus margins. Pollen grain diameter ranges from 44.69 um in the long-styled morph of /Vivenia corymbosa to over 80 um in Klattia stokoei and Witsenia maura (Table 2). Differences in pollen grain size among the species correlate generally with differences in style length. Klattia and Witsenia have the longest styles and largest pollen in the group, and K. sto- koei the longest styles in that genus. Nivenia le- vynsiae and N. concinna, however, do not follow this trend, having shorter styles than one would expect from their comparatively large pollen grains. In four of the five heterostylous species of Niv- enia the grains of the long-styled morph are sig- nificantly smaller (Table 3). Pollen size differences between morphs of the four heterostylous species late directly with differences in style length also in the complementary morph (Goldblatt & Bern- hardt, in press). Exine sculpturing does not differ between morphs within the heterostylous species, ut there are notable di the species. Nivenia binata exhibits the greatest de- gree of sculpturing and V. capitata the least (Figs. [maa differences between » DISCUSSION The pollen grains of Nivenia and Klattia con- form fairly closely to the presumed basic type for Iridaceae and for the monocots in general, in which reticulate grains appear to be fundamental (Schulze, 1971; J. Walker, pers. comm.). Similar grains are found in species of Aristea (likewise Nivenioideae) and in numerous genera of Iridoideae, excluding Iris, in which there are multiple unusual special- izations, particularly in the form of the aperture (Schulze, 1971). A group of New World genera of Iridoideae belonging to the tribe Tigridieae stand out in having bisulcate grains (Schulze, 1971), clearly a secondary condition in the tribe. Members of subfamily Ixioideae also differ markedly from this basic pollen type, having a tectate-microper- ith supratectal spinules (Erdtman, Goldblatt & Stein, 1988). forate exine w 1952; Schulze, 1971; 1106 Annals of the Missouri Botanical Garden FIGURES 1 76. — 1.

These two species appear to be indepen- dently specialized based on differences in flower 1108 Annals of the Missouri Botanical Garden and inflorescence morphology (Goldblatt, in prep.), and their similar pollen sculpturing is presumably convergent. The occurrence of ridged muri in N. binata and N. stenosiphon, however, appears to be an indication of close taxonomic relationship as it is correlated with two specialized characters re- stricted to these species: blue anthers and pollen, and large, dry, brown, crisped bracts (Goldblatt, in prep.). The grains of Witsenia, with their large supra- tectal gemmae, are clearly derived. These distinc- tive gemmae, observed by Schulze (1971) under light microscopy, are unique in Iridaceae and make the pollen grains of this genus immediately rec- ognizable. The presence of an unusual exine in Witsenia emphasizes the taxonomic isolation of this genus, distinctive in its unusual floral and inflores- cence morphology. Any significance in the elabo- rate exine sculpturing of Witsenia in relation to its mode of pollination remains to be demonstrated. Pollen sculpturing does not provide any char- acter uniting the three shrubby genera of Cape Iridaceae, but within the alliance trends of spe- cialization are evident in Nivenia, and the supra- tectal gemmae in Witsenia constitute an autapo- morphy for this genus. Mulcahy's (1965) report of a difference in size between the grains of the short- and long-styled morphs of N. binata is substantiated by our ob- servations, although we noted a smaller size dif- ference (ratio of grain size between short- vs. long- styled morph 1.11 compared with 1.3 reported by Mulcahy). We were unable to confirm Mulcahy's observation of differences in the size of the lumina of the exine reticulum between short- and long- styled grains in N. binata, nor did we record mea- surable differences in lumina size in the other het- erostylous specie e close similarity of the exine sculpturing and small, though statistically significant, differences in pollen grain size between the two style morphs in four of the observed heterostylous species of Niv- enia are consistent with similar observations in many heterostylous taxa (Ganders, 19 Rich- ards, 1986). In Nivenia the noolar ea differ- ences between the style morphs of the heterostylous species appear not to be accompanied by the ex- pected self-incompatibility characteristic of most heterostylous plants (Goldblatt & Bernhardt, in press).

SEED MORPHOLOGY OF SISYRINCHIUM (IRIDACEAE— SISYRINCHIEAE) AND ITS ALLIES! Peter Goldblatt,? James E. Henrich,’ and Richard C. Keating? ABSTRACT Seeds of 25 species of sects. Sisyrinchium, Echthronema, Eriphi ilema, and iai of the large North and South — genus Sisyrinchium were examined using the scanning e electron mic eeds of representative species of related genera in tribe Sisyrinc ditas. Seeds of sects. Sisyrinchium , are s with Vg nd surfaces, and often have a iuis depression, compared with s and Echh ronema are more or less Pomen a large, half-circumferential wing. Seeds o probably derived specializations. Based on seed charac and light microscope and o have brown, more or lessa ular seeds ms 8, to the other genera of Sisyrinchieae, particularly Phones than to sects. Sisyrinchium or Echthronema. In the course of a systematic study of the New World genus Sisyrinchium for Flora Mesoamer- icana (Henrich & Goldblatt, 1987, in press a) and Flora de Nicaragua (Henrich & Goldblatt, in press b) our attention was drawn to the unusual rounded, blackish, umbilicoid seeds of the genus. The seeds were novel to us in Iridaceae and distinguish Sisy- rinchium from all other genera in the family. Seed characters were also useful in establishing species limits within the genus. We found no ad- equate description or record of Sisyrinchium seeds in the literature, and Huber (1969) did not spe- cifically describe them in his extensive study of the seeds of lilioid monocots. However, Cholewa & Henderson (1984) included SEM examination of six North American species of sect. Sisyrinchium, and Rodriguez (1986) mentioned color and surface texture in his revision of the Chilean species of Sisyrinchium. With this background we undertook the present survey of the seeds of Sisyrinchium and its allies in tribe Sisyrinchieae of subfamily Iridoideae (clas- sification after Goldblatt, 1990). Sisyrinchium as presently constituted (Bentham & Hooker, 1883; Baker, 2) study includes a small but representative sample of the total and is sufficient to satisfy our purpose in documenting the basic seed types found in the genus and to allow a valid comparison with allied genera. We included taxa from the two large and apparently natural sects. Sisyrinchium (— sect. Bermudiana of several authors) and Echthronema (Bentham & Hooker, 1883) and the smaller sects. Eriphilema and Nuno. Related genera of tribe Sisyrinchieae (sensu Goldblatt, 1990) examined for comparison were Libertia, Ona, Orthrosanthus, Phaiophleps, Solenomelus, and Tapeinia. Seeds of Chamelum, which belongs in this alliance, were not available. The southern African Bobartia and the Australian Diplarrhena, the remaining genera of the tribe, appear to be more distantly related to the Sisyrinchium complex and neither was in- cluded in our survey. Sections Eriphilema and Nuno and the other genera examined have seeds comprises over 100 species. Our !

Sisyrinchium and Echthronema. MATERIALS AND METHODS Mature seeds were assembled from herbarium material, and in a few cases fresh field-collected seeds were examined (Table 1). We excluded seeds that appeared deformed or showed signs of fungal infection. Seeds were examined under the light microscope for size and color, and then prepared for the scanning electron microscope (SEM) study by attachment with water-soluble white glue to aluminum stubs and sputter coating with 500—700 À of gold. They were examined in an ISI Super IIIA SEM at 15 kV. OBSERVATIONS COLOR Seeds of all the species of Sisyrinchium sects. Sisyrinchium and Echthronema are blackish (Ta- ble 2). Surface color intensity ranges from a fairly glossy, intense black to matte and dark gray. As we used seeds almost exclusively from herbarium specimens, we are uncertain how much significance to attribute to the color variation as ripening may have been affected by the rapid drying, and the final seed appearance may thus not be the same as in nature. Seeds of Sisyrinchium sects. Eriphilema and Nuno and of the genera Libertia, Ona, Orthro- santhus, Phaiophleps, Solenomelus, and Tapei- nia are shades of brown (Table 2), most often red- brown, presumably the basic condition in the family (Huber, 1969) and an indication of the presence of the pigment phlobaphene. Some species, for example Orthrosanthus occissapungus, have light brown seeds, an apparently significant character at the species level. SHAPE AND SIZE The number of seeds per locule of the three- chambered capsules of Sisyrinchieae was not re- corded in our study, but all species examined have multiseeded loculi. The effect of crowding and al- teration of shape by mutual pressure within the locules (Huber, 1969; Wagner & Goldblatt, 1984) was noted to some degree in most species. Angular seeds characterize Libertia and Orthrosanthus (Figs. 1-3). Phaiophleps and Sisyrinchium sect. Eriphilema have less sharply angular seeds (not illustrated), sometimes tending toward rather ob- tusely angled and differing consistently in basic shape from the rounded seeds of sects. Sisyrin- chium and Echthronema. Seeds of two species of Solenomelus are cylindric to barrel-shaped with distorted angular ends (e.g., S. segethii, Fig. 5). In a third, possibly new, species of Solenomelus (Fig. 6) the seeds have a broad, membranous, half- circumferential wing. The seeds of Orthrosanthus occissapungus (Fig. 3) have the proximal and dis- tal ends produced into winglike processes, but other species of the genus have angular seeds, as illus- trated by Takhtajan (1985) for O. chimboracensis. In Tapeinia (Fig. 4) the seeds are nearly pyriform to elongate-pyriform, narrowest at the chalazal end. The raphe is usually distinct and terminates in a small depression in which we assume the micropyle is located. The least effect of crowding was found in sects. Sisyrinchium and Echthronema. There, except for the small persistent funicle, the seeds (Figs. 7-18) are nearly regularly spherical to rounded or sometimes somewhat depressed (e.g., S. chiricanum, Fig. Seed size varies considerably (Table 2) within genera. Thus in Sisyrinchium, S. minus has seeds 6 x 0.4 mm, whereas those of S. chiricanum are ca. 2.5 mm in diameter. The seeds of Soleno- melus are even larger, with a maximum length of 5.5 mm attained by Solenomelus sp. There is a regular pattern of small, evenly spaced, irregularly rounded depressions oriented in lines running along the long axis of the seeds of all three species of Solenomelus (Figs. 5, 6). In Solenomelus sp. these depressions are limited to the area cov- ering the seed body. A conspicuous, often large pit, which we here call an umbilicus, is an outstanding feature of the seeds of most species of sects. Sisyrinchium (Figs. 9, 10) and Echthronema (Figs. 13-18) (Table 2). The umbilicus straddles the raphe, either between the hilum and the micropyle (Figs. 17, 18), or the umbilicus includes the micropyle (Figs. 13, 15). SURFACE MORPHOLOGY AND MICROSCULPTURING Outlines of the testa cells often form a pro- nounced reticulum owing to the typical condition in Iridaceae for the outer periclinal walls to collapse while the thickened anticlinal walls persist (e.g., Figs. 1-4). The seed surfaces thus have a reticulate appearance the surfaces exhibit little texture and in S. trinerve Fig. 15) are nearly smooth. We did not find ex- amples of the somewhat irregularly granular sur- . In some species of sect.

No granular microsculp- turing was noted in species of any other genus included in our surve In Solenomelus the longitudinal lines of more or less circular depressions do not correspond to the surface cells. The depressions are larger than the individual cells, the outlines of which can be clearly seen over the entire seed surface in S. segethii (Fig. 5), but are rather obscure in Soleno- melus sp. (Fig. 6) and S. pedunculatus. In the latter the peripheral cells of the seed are unusual being elongate and they have a remarkably smooth surface (Fig. 20) DISCUSSION Most Iridaceae have seeds of a light to middle brown, sometimes reddish brown (Huber, 1969; Wagner & Goldblatt, 1984), the coloration attrib- uted to the presence of phlobaphene (Huber, 1969). A few exceptions include the glossy black seeds of Belamcanda (tribe Iridoideae) and Babiana and Antholyza (tribe Ixioideae), and the bright orange seeds of Chasmanthe (also Ixioideae) and Neo- marica variegata (Iridoideae tribe Mariceae). Whether the black color in the above genera or in Sisyrinchium can be attributed to the presence of phytomelan, a dense carbon substance that is regarded as important in the higher systematics of the lilioid monocots (Dahlgren & Rasmussen, 1983; Dahlgren et al., 1985), is unknown. The most common seed shape in lridaceae is more or less regularly angular (Huber, 1969) but globose or subglobose seeds are not uncommon. Winged seeds occur in Gladiolus and its close allies (Ixioideae), and discoid seeds are characteristic of ee details of seeds of Sisyrinchium commutatum (19) and Solenomelus pedunculatus some species of /ris and Moraea (both Iridoideae- Irideae) and Diplarrhena (Sisyrinchieae). The half- circumferentially winged seeds of Solenomelus sp. are reminiscent of those of Gladiolus (which have completely circumferential wings) and represent a notable example of convergence. Until now the blackish seeds encountered Sisyrinchium appear not to have been regarded as particularly significant, although the basic dif- ferences in seed color have been noted by Rodri- guez (1986), black in species attributable to sects. Sisyrinchium and Echthronema and brownish in sect. Eriphilema. Moreover, the more or less glo- bose shape and the frequent presence of a large umbilicus along the raphe, either between the hilum and micropyle or including the latter, appear to have attracted little attention except for occasional mention in species descriptions. We believe that these features have considerable taxonomic signif- icance, particularly in a. genus that is relatively unspecialized in the family and has few other dis- tinguishing characteristics. A conclusion that appears warranted is that the black, (apomorphic) condition in sects. Sisyrinchium and globose, and umbilicoid seeds are a derived Echthronema. It is likely, though by no means certain, that this seed, including the umbilicus, is the basic type in the two sections despite the fact North and South American species of both sections. that an umbilicus is not present in a few Seed data indicate that sects. Sisyrinchium and Echthronema should be considered sister taxa more closely allied to each other than to sects. Eriphi- lema and Nuno. The possibility that sects. Eri- philema and Nuno may be more closely allied to other genera of Sisyrinchieae, Phaiophleps in par- Volume 76, Number 4 1989 Goldblatt et al. 1117 Seed morphology of Sisyrinchium ticular, than to the rest of Sisyrinchium will be explored in a future paper dealing with the phy- logeny of Sisyrinchieae.

MENDONCIA (ACANTHACEAE) FROM THE VENEZUELAN GUAYANA! ABSTRACT ecent expeditions in the Venezuelan Guayana have resulted in additional new taxa in the genus d ea eae). The following is an effort to place these novelties on record for the convenience of other taxonomists prior to the publication of the Flora of the Venezuelan Guayana. Four new Venezuelan Guayana species of Me ndoncia, M. steye dea M. neblinensis, M. williamsii, and M. coriacea, are described, Juétratea, por compared with their closest relatives There are approximately 60 species of Men- doncia in Central and South America and in trop- ical Africa and Madagascar. The genus, named for Cardinal Mendonca, Patriarch of Lisbon, consists of twining herbaceous or sometimes suffrutescent climbers bearing cylindric red, white, or cream- colored axillary flowers with purple streaks in the throat. Each flower is subtended by a pair of con- spicuous, green, more or less connate bracts. Most taxa are limited to wet virgin forests and thickets at elevations between 50 and 1,000 m. Due to the fact that lianas and vines are generally poorly known and collected in the tropics, and given the super- ficial similarity of many of the species, the tax- onomy of the genus is rather difficult. In an attempt to identify recent collections of Mendoncia from the Venezuelan Guayana, I have found four un- described species of the genus. KEv TO THE VENEZUELAN GUAYANA SPECIES OF MENDONCIA la.

It differs markedly from M. sprucei in that the latter species has green bracts 2 cm long and 1 cm broad, sparingly appressed- pilose pubescence on the leaf blades, and corollas 3 cm long. In contrast, M. neblinensis has yel- lowish to brownish green bracts cm long and 1.3-1.7 cm broad, glabrous leaf blades, and corollas 3.5 cm long. Lindau (1897) in his de- scription of M. sprucei did not indicate the color of the corolla, nor did Turrill (1919) in his revision of the genus. Leonard (1951) described the corolla f M. sprucei as cream colored with purple streaks 5: in the throat. I believe this to be in error; the corolla of M. sprucei is also bright red. Turrill (1919) stated in his discussion that M. sprucei appears to be very closely related to the red-flow- ered M. aspera Nees and that perhaps M. sprucei was only a variety of M. aspera.

Terminalia chicharronia Wright ex Sau- valle. Restricted to Cuba, Haiti, and the Dominican Republic, this species is very variable in the size and shape of the leaves and in the amount of indumentum on the branchlets, leaves, and inflo- rescence. These characters reveal four reasonably well geographically separated taxa recognized here as subspecies. Terminalia chicharronia was based on Chi- charronia intermedia A. Rich. meg which in turn was based on Sagra 185 and 281. The spec- imens at G are the best ones, but there is no evidence that Richard saw them. In P there is one sheet with three shoots—two in flower and one in fruit — which Richard did see. The label says “Her- barium Richard. No. 185, Combretum sp. nov., Guanabo, Marzo 1829, Coll. R. de la Sagra." The two flowering shoots are here designated as lec- totype because in G there is a note from Sagra saying that no. 185 was sent first and was flowering, and no. 281 was sent later (both March 1829) and fruiting. This typification fixes subsp. chicharronia as the subspecies with densely pubescent to rufous tomentose leaves with strongly raised venation. It occurs most commonly in eastern Cuba (prov. Ori- ente), where it is sympatric with the closely related T. eriostachya A. Rich., which differs by having larger flowers, longer inflorescences, and glabrous styles.

Moreover, although Ramatuella is still recognizable by the combination of characters out- lined by Exell & Stace, it seems far better reunited with Terminalia, as its distinction is based on only one of several combinations of characters found in Terminalia. Accordingly, we reduce it to sectional — status. ! Department of Botany, University of Leicester, Leicester LEI 7RH, England. ANN. Missouni Bor.

Diptera, which contains T. argentea. Of the species in sect. Australes, T. uleana differs from T. australis Cam- bess. and T. reitzii Exell in fruit shape and from T. triflora (Griseb.) Lillo by having wider leaves and wider fruits with a differently shaped wing. The fruit wing of 7: uleana is often curved down- ward (retrorsely), and this character is diagnostic; a third rudimentary wing is often present. The species has not been found since 1889. 6.

Various workers have placed this species in Solanum, Cyphomandra, and Bassovia. It was first described as Pionandra allophylla by Miers (1854) in Seemann's Botany of the Voyage of the H.M.S. Herald. Pionandra, erected by Miers in 1845, is synonymous with Sendtner's genus Cyphomandra, created a few months earlier (Sendtner, 1845). Accordingly, P. allophylla was transferred to Cyphomandra by Hemsley in 1882. Standley transferred Cypho- mandra allophylla to Solanum in 1927 without explanation. Georg Bitter, unaware of Miers's species, in- dependently described the species as Solanum el- lipsoideibaccatum Bitt. in 1913. He noted that the tapered anthers with small terminal pores re- semble those of Solanum subg. Leptostemonum (Dun.) Bitt. but surmised that his species probably represented a new section of Solanum. In 1914, Bitter received specimens illustrating the lobed leaves that often occur on the lower branches in this species. He emended his original description to include these lobed leaves and described a new variety, var. ficilobum Bitt., hibiting almost exclusively lobed leaves. from a specimen ex- Pittier (1947) later transferred Solanum ellipsoideibac- catum to the genus Bassovia, an error that Hun- ziker (1969) later corrected. Solanum ellipsoi- deibaccatum and its variety ficilobum are regarded here as synonyms of the earlier name Solanum allophyllum (Miers) Standley. Standley's placement of the species in Solanum was followed in the older literature (Morton, 1944; 1965; Standley, 1928), but more recent workers have interpreted it as be- longing in Cyphomandra (Bohs, 1986, 1988; Child, 1984; D'Arcy, 1973). All those who have included the species within Cyphomandra have noted its Romero-Castaneda, atypical anther structure, but placed it in. Cy- phomandra on the basis of other similarities. Child (1984) called attention to its anomalous features !

Allophylla Child to accommodate this species and the allied Cyphomandra phytolaccoides (Rusby) Child (— Solanum mapiriense Bitter). Why has the generic placement of this species been so uncertain? Though $. allophyllum differs from Cyphomandra in a number of morphological characters, it has been considered as a Cypho- mandra because, at least superficially, this species shares with Cyphomandra the very features that have been used to distinguish Cyphomandra from Solanum. Both S. allophyllum and Cyphomandra have: 1) a growth habit characterized by a single erect trunk and a spreading crown of three main lateral branches, 2) three-leaved sympodial units with the inflorescences situated mainly in branch forks, and 3) tapered anthers that are thickened on the abaxial surface. Growth habit and branching pattern have been recently proposed as new char- acters that distinguish Cyphomandra from Sola- num (Bohs, 1986). Anther structure traditionally separates the two genera (Sendtner, 1845). Herein | reexamine the morphological features of Cy- phomandra and S. allophyllum with emphasis on these three proposed generic characters. New in- formation about the breeding system and mor- phology of the chromosomes, pollen, and seeds of 5. allophyllum and Cyphomandra is also com- pared. These investigations help to ascertain the generic position of this species and shed new light upon the critical characters that separate Solanum and Cyphomandra. MATERIALS AND METHODS Morphological studies were carried out using living plants, and dried specimens from the follow- ing herbaria: A, BM, C, E, F, GH, K, M, MO, NY, P, US, and WIS. Voucher information for greenhouse material is given in the Appendix. Growth habit is defined by reference to the ar- chitectural models of Hallé et al. (1978). This system takes into account the dynamic aspects of plant growth rather than simply considering the shape of a plant at any one time. Terminology relating to architecture and branching pattern like- wise follows Hallé et al. (1978) Compatibility studies were conducted on plants growing in pollinator-free greenhouses at Harvard University and at the University of Vermont. One to several accessions were grown of each species. Plants were either selfed or outcrossed, between accessions and between individuals of the same accession, by tapping pollen onto a clean glass slide and rubbing it across the stigma of the female parent. For observations of meiotic chromosomes, flower buds were fixed in Farmer's solution (3: 1 absolute ethanol: glacial acetic acid) or Carnoy's fixative (6: 3:1 absolute ethanol: chloroform:glacial acetic acid) shortly after sunrise. Preparations were stained with 1-2% acetocarmine and squashed in Hoyer's solution. Root tips for mitotic chromosome obser- vations were pretreated for up to 24 hours in a saturated solution of paradichlorobenzene at ap- proximately 4?C, then fixed in Farmer's solution for up to 24 hours. Root tips were then stored in 70% ethanol until use, hydrolyzed in 1 N HCI for 10 minutes at 60°C, and stained as above Histological preparations of anthers were ob- tained from flowers that had been fixed in FAA, dehydrated in an alcohol series, embedded in Para- plast, sectioned, and stained with safranin/ fast green. Pollen measurements were made from fresh pol- len samples obtained from greenhouse plants. The grains were shaken into a mixture of 1-2% ace- tocarmine and Hoyer's solution and allowed to stand for exactly 10 days before measurement. Mea- surements of the polar and equatorial axes on 30 grains per sample were made from a 400 X camera lucida projection onto a Zeiss ZIDAS digitizer. Pol- len diameter was measured on stained grains only, and was taken as the distance between the inner- most layers of the pollen grain wall. Pollen volume was calculated using the formula for the volume of an ellipsoid, V = rPE*/6, where E is the equa- torial diameter and P is the polar diameter. An analysis of variance revealed no significant differ- ence between equatorial diameter as measured in polar and equatorial views, so P and E were mea- sured in equatorial view only. Pollen samples for scanning electron microscope SEM) photos were taken from dried herbarium material. The grains were mounted on the stub with double-stick tape and coated with gold-palla- dium. Fresh pollen from greenhouse plants that was critical-point dried and coated appeared col. lapsed under the SEM RESULTS DISTRIBUTION, ECOLOGY, AND MORPHOLOGY able 1 compares the morphological and eco- logical characteristics of 5. allophyllum and Cy- phomandra discussed below.

Solanum allophyllum has been collected from a single site in Honduras and is more abundant from Costa Rica and Panama through northwestern South America (Fig. 1). though the plants are found in a variety of habitats, in Costa Rica and Panama the species seems to grow in drier sites than Cyphomandra species, which are almost always mesic-forest dwellers. No herbarium collections of this species from Costa ica or Panama were made in the months of Jan- h, the dry season in these regions (Coen, allophyllum persists by losing its leaves during the dry season and perennating via its roots or larger shoots, but further field studies of this species are needed to ascertain its phenology. In the green- house the plants flower and fruit within five months from planting. This generation time is much shorter than most cultivated cyphomandras, which often take several years to reach reproductive age. Sola- j. num allophyllum is a weakly woody shrub that rarely grows over 1.5 m tall (Fig. 2), in contrast to the majority of Cyphomandra species, whic develop abundant secondary xylem and may reach heights of up to 10 m. e subcordate to truncate leaf bases of 5. al- lophyllum are decurrent along the petiole (Fig. 3). The leaves of Cyphomandra usually have cordate or less frequently truncate bases; decurrent leaf bases occur only in C. fragilis Bohs. The inflorescences of S. allophyllum are un- species of Cyphomandra. In the presumably also in the field, the fruits fall to the branched and bear 4-6 flowers on short pedicels 4-6 mm long. Those of Cyphomandra can be branched or unbranched, typically bear more than 10 flowers, and have pedicels longer than 10 mm. e shape of the corolla of S. allophyllum can best be described as rotate-stellate (sensu Correll, 1962): fairly long corolla lobes are present, but these are connected at the base by abundant in- terpetalar tissue that is plicate in the bud (Fig. 4 This type of corolla is often seen in Solanum subg. Potatoe (G. Don) D'Arcy. In contrast, the corolla f Cyphomandra has various shapes, but never rotate-stellate or plicate. Solanum allophyllum produces some of the most distinctive fruits in the Solanaceae. At maturity, they are glabrous and white or occasionally orange mottled with green or purplish markings. The fruits are ellipsoidal or oblong in outline, and are laterally compressed and appear elliptic in cross section (Fig. fruits differ from those of all species of Cypho- mandra in color and shape, and the seeds are much smaller and more numerous than those of any ground while still hard and bitter and then ripen for several weeks before becoming soft and pal. atable and emitting a strong sweet odor. They are most likely dispersed by ground-dwelling animals. Those of Cyphomandra are held on the tree and 1131 greenhouse and [T ' 1 1T 1^ —1 O 100 200 300 400 500 600 miles FIGURE 1. only fall after they are completely ripe. Their dis- persal agents are unknown, but they may be at- tractive to birds or bats. ARCHITECTURE The distinctive growth habit or shape of S. al- lophyllum and many species of Cyphomandra is a conspicuous feature that allows the plants to be recognized easily in the field. In terms of archi- tecture, however, Cyphomandra and S. allo- phyllum are similar only in the initial phase of their growth (Fig. 6). In both, the seedling axis produces a single orthotropic, or upright, trunk with the leaves spirally arranged in a 2/5 phyl- lotaxis. This trunk ends with the production of a terminal inflorescence. Usually three plagiotropic, or horizontal, shoots then elongate from axillary buds located just below the inflorescence to produce a spreading crown (Fig. 6A, D). Further branching within the crown occurs by sylleptic elongation of axillary shoots immediately below the successive terminal inflorescences; thus the crown is composed of a series of sympodial units where all the flowers 1132 Annals of the Missouri Botanical Garden ag 10 O 200 400 600 800 1000km 7 : M i rl s e m et SM euh Distribution of Solanum allophyllum. (Base map copyright 1979 by the University of Utrecht.) and fruits are borne. Beyond this, Cyphomandra and S. allophyllum diverge in their architecture. In Cyphomandra, after continued sympodial rowth and numerous episodes of flowering and fruiting, the plagiotropic branches begin to senesce. new trunk then arises proleptically from an ax- illary bud on the old trunk below the branch tier and continues orthotropic growth until another ter- minal inflorescence and branch tier is produced. In this way, the main axis is composed of successive sympodial trunk modules bearing spatially and tem- en separated reproductive crowns (Fig. : C). I have seen this architecture in at least six species of Cyphomandra, and it is probably wide- spread in the genus. [n contrast to Cyphomandra, 5. allophyllum does not produce successive trun modules. The whole plant in 5. allophyllum is therefore equivalent to a single structural unit of the Cyphomandra growth form. The architecture of Cyphomandra described above occupies an intermediate position between Prevost's and Nozeran's models in the scheme of Hallé et al. (1978). Both models have an ortho- tropic sympodial trunk and tiered plagiotropic Volume 76, Number 4 1989 Bohs 1133 Solanum allophyllum FIGURES 2-4. Scale bar = 2 cm. ywers. Scale bar = m branches. In Prevost's model both the trunk and plagiotropic branches generally have spirally ar- ranged leaves, whereas in Nozeran's model the orthotropic and plagiotropic branches have highly contrasting leaf arrangements, usually with spiral phyllotaxis on the trunk and distichous phyllotaxy on the branches. Plagiotropy of the branches in Nozeran's model is perpetuated if a crown branch is independently propagated, whereas in Prevost's model the plagiotropy of the crown branches is usually lost when they are separated from the trunk. he leaf arrangement of the crown branches in Cyphomandra is affected by pronounced twisting Solanum allophyllum. — 2.

Leaves from trunk. of the axes and differential elongation of branch internodes (see section on branching pattern below for a more detailed description of leaf arrangement, and Danert, 1958, 1967, phology of the shoot systems in Solanaceae). There- for comparative mor- fore, although the leaf arrangement on the plagio- tropic shoots is not distichous, the crown branches show pronounced dorsiventral symmetry in con- trast to the radial symmetry of the spirally arranged trunk leaves. Cuttings taken from the crown region of C. betacea, C. diploconos, and C. diversifolia produce lower, bushier plants than those taken from the upright axes (Fletcher, 1979; pers. obs.), 1134 Annals of the Missouri Botanical Garden FIGURE 5. so these species apparently exhibit the inherent nature of plagiotropy in the crown branches char- acteristic of Nozeran's model. At least until an accurate interpretation of leaf arrangement on the plagiotropic shoots is available, it is probably best to consider Cyphomandra as being intermediate between Prevost's and Nozeran's model The architecture of S. allophyllum does not strictly conform to any of the models defined Hallé et al. (1978). It most closely resembles Leeu- wenberg's model, which is exhibited by several n. ies of Solanum and Capsicum (Hallé et al., 1978). However, in Leeuwenberg's model, all the axes are orthotropic and equivalent, whereas in S. allophyllum there is evident differentiation be- tween the trunk and crown branches. Perhaps the yest way to characterize the architectural form of 5. allophyllum is to consider that it may have been derived by "fragmentation" from more woody counterparts with multiple trunk modules, such as those seen in Cyphomandra. Fragmentation oc- curs when only a portion of the original tree model is expressed, and is commonly seen in herbaceous relatives of woody plants with more strongly de- veloped trunk modules. Should it indeed be the case that the architectural form of S. allophyllum is related in this way to more extensive tree models, it may argue that this relatively herbaceous species has been derived by reduction and fragmentation from woody ancestors. Fruits of Solanum allophyllum. Scale bar — 2 cm. BRANCHING PATTERN Three- to four-leaved sympodial units are the rule within the crown of nearly all species of Cy- phomandra (Fig. 7); the only known exception is C. corymbiflora, which frequently has five-leaved sympodia. Three-leaved sympodial units are also characteristic of S. allophyllum. Commonly, the leaf subtending the renewal shoot is carried up to a point nearly opposite that of the first leaf pro- duced on the axillary shoot so that the seemingly opposite leaves are actually members of successive sympodial shoot generations. In S. allophyllum and in many species of Cyphomandra, two renewal shoots grow out from below the terminal inflores- cence, thus situating it in a branch fork. This shoot structure was previously thought to be peculiar to Cyphomandra (Bohs, 1986), and its presence in 5. allophyllum was evidence supporting the inclu- sion of the species within Cyphomandra. Members of Solanum may have one- to many-leaved sym- podial units, and the inflorescences may be axillary, extraaxillary, opposite a leaf or leaf cluster, or rarely in branch forks. Subtle differences exist in leaf and shoot ar- rangement within the crown branches of Cypho- mandra and S. allophyllum apart from the leaves and branches making up the sympodial shoot struc- ture. In S. allophyllum, nearly all the axillary buds of the crown expand into short shoots, giving the Volume 76, Number 4 8 Bohs 1135 Solanum allophyllum ES - C FIGURE 6.

In Cyphoman- dra, sylleptic growth is restricted to the axillary buds immediately subtending the terminal inflores- cences of the sympodial units, the rest of the buds remaining dormant unless released by pruning or breaking the tip of the branch. In the greenhouse, S. allophyllum also undergoes pronounced sea- sonal reiteration, with expansion of many buds on the trunk by prolepsis and elongation of the short shoots of the crown. It is not known whether 5. allophyllum reiterates in this way under natural conditions; as already mentioned, it may die back to the main stem each year and produce a new plant conforming to the initial model at the begin- ning of the rainy season. ANTHER MORPHOLOGY Tapered anthers with an abaxial thickening oc- cur in Cyphomandra and S. allophyllum (Figs. 8, 9). Anther shape is not a definitive characteristic of either genus, however; tapered anthers occur in other species of Solanum (e.g., in subg. Lepto- stemonum (Dun.) Bitt., subg. Potatoe (6. Don) D'Arcy, and sect. Herposolanum Bitt.), and al- though they are common in Cyphomandra, they are not exhibited in all of its species. There is no present evidence to indicate that tapered anthers are homologous within or among these groups. A more important criterion for distinguishing Cy- phomandra from Solanum is found in the enlarged anther connective. In Cyphomandra, the anther connective is usually very thickened and prominent abaxially and is sharply delimited from the thin- Diagram of branching pattern in the crown FiGURE 7. of Cyphomandra and Solanum allophyllum. Black and — white shading denotes successive sympodial units. The subtending leaf (S) of the axillary shoot has been carried up to a level subopposite the first leaf on this shoot (L,). The diagram shows a species with four-leaved sympodia; in three-leaved sympodia, the leaf L, is absent — walled anther thecae. Anthers of Solanum can be thickened in various ways, but they never have a distinct and abaxially prominent connective. Solanum allophyllum has a thickened area on the abaxial side of the anther that has been inter- preted as an enlarged connective like that of Cy- phomandra, and has led to the inclusion of S. allophyllum within Cyphomandra. Microscopic cross sections through the anther region o lophyllum and a representative of C mai C. diversifolia (Dun.) Bitt., show that anther struc- ture is very different in the two taxa. In Cypho- mandra (Fig. 8), the thickened portion is expanded TABLE 2. Compatibility studies in Cyphomandra and Solanum.

In contrast, S. allophy llum appears to be self-compatible. Neither S. allo- phyllum nor C. betacea sets fruits in pollinator- free greenhouses without deliberate pollination. This indicates that these two species may not be autog- amous and require a pollinator to transmit self pollen, or that they may be apomictic and pseu- dogamous. The style in S. allophyllum is not visible directly after anthesis, but elongates and emerges through the anther cone after the anthers dehisce. Thus, protandry may prevent selfing in this species. CYTOLOCY The most compelling evidence for the exclusion of S. allophyllum from Cyphomandra comes from chromosome studies.

This chromosome number is common in Solanum and have n — A. ————— 10^ FIGURE 11. Camera lucida drawings of mitotic ER in root tips. — A. C yphomandra acuminata. — Solanum allophyllum. A and B at same magnificatior the Solanaceae in general. However, chromosomes of the two taxa differ markedly in size (Figs. 10, 11). Investigations of seven species of Cypho- mandra have revealed that the chromosomes in this genus are very large, averaging about 8 um in length with a range of approximately 3 to 14 um (Bohs, unpublished data). DNA amounts as measured by flow cytometry were among the larg- est yet known in the Solanaceae (Pringle & Mur- ray, in press). In contrast, both the mitotic and meiotic chromosomes of 5. allophyllum range be- tween | and 2.5 um in length and are thus on the order of 2.5 to 5.5 times smaller than those of Cyphomandra. POLLEN Pollen grains of S. allophyllum and Cypho- mandra were examined for potential taxonomic characters. The grains of 5. allophyllum are tri- colporate and have exine sculpturing consisting of very small rounded granules best observed with SEM (Figs. 12-14). Cyphomandra pollen is also tricolporate, and most species have granular exine sculpturing like that of 5. allophyllum, although several Cyphomandra species (e.g., . pendula (R. & P.) Sendtn. and C. pilosa Bohs) lack such granules and have a psilate exine. Although the aperture type and exine sculptur- ing show few taxonomically useful differences, the grains of Cyphomandra and S. allophyllum do differ somewhat in size and shape. Table 3 com- pares the pollen dimensions and volume of S. al- lophyllum and seven species of Cyphomandra. In the terminology of Erdtman (1952, 1969), all species of Cyphomandra have spheroidal or pro- late spheroidal grains, whereas those of 5. allo- phyllum are more elliptic in equatorial view and fall into the subprolate shape class. All taxa ex- c 1138 Annals of the Missouri Botanical Garden FicunEs 12-14. 14. Scale bar = 0.5 amined have small- to medium-sized grains (again using Erdtman's terminology), but those of 5. al- lophyllum are much smaller than any species of Cyphomandra. Cyphomandra grains have vol- umes about 2.5 to more than 10 times larger than those of S. allophyllum. SEED SIZE The seeds of S. allophyllum are substantially smaller than those of any of the Cyphomandra species examined (Table 3), ranging from about Y, to Y, the size of Cyphomandra seeds. DISCUSSION There are numerous differences in ecology, phe- nology, and morphology between 5. allophyllum and Cyphomandra, but these alone do not permit an unequivocal placement of the species in either Solanum or Cyphomandra. Architecture and some aspects of the branching pattern further differen- tiate S. allophyllum from Cyphomandra, but again not enough to place the former definitively in either genus. A problem with the use of these characters is the wide range in architecture and branching pattern seen in Solanum. It looks as if these two Pollen grains of Solanum alloph yllum. 13. Scale bar = 10 um. 12. Scale bar = l um. characters cannot be as useful in distinguishing Cyphomandra and Solanum as was previously thought. In contrast, a consideration of anther morphol- ogy shows that S. allophyllum does not have a distinct and enlarged anther connective like that of Cyphomandra. The anther structure formerly interpreted as a similarity between it and Cypho- mandra is now revealed to be a difference that separates the two taxa. It appears that the presence of an enlarged anther connective is the most re- liable morphological criterion for distinguishing Cy- phomandra from Solanum. he fact that 5. allophyllum is self-compatible (SC), whereas the majority of Cyphomandra species are self-incompatible (SI), is at least an implication that 5. allophyllum is not a Cyphomandra. Bot SC and SI are known in Solanum, so the inclusion of 5. allophyllum in Solanum is consistent on the basis of this character. Self-compatibility in C. indication of its relatively recent origin. SC is con- sidered to be a derived character in the Solanaceae (de Nettancourt, 1977; Whalen & Anderson, 1981). If this applies equally well to Cyphoman- dra, then the self-compatibility of the cultivated betacea could be an Volume 76, Number 4 1989 Bohs 1139 Solanum allophyllum TABLE 3.

The present study shows that there is a tendency toward large chromosomes in Cypho- mandra. This appears to be a very useful character distinguishing Cyphomandra from Solanum. Fur- ther studies of chromosome size in the Solanaceae are needed to determine if this character is con- sistent in other species. Comparison of genome sizes between putatively primitive and derived members of s different plant groups demonstrates that chang an occur in either direction (Ob & Khoshoo, 1986). Additional chromosome studies coupled with morphological data may even- tually allow us to determine trends in the evolution of genome size in Cyphomandra, Solanum, and other solanaceous genera. The exine sculpturing of 5. allophyllum pollen also resembles that of Solanum. Anderson & Gen- sel (1976) and Edmonds (1984) reported similar granular exine sculpturing in Solanum sects. Ba- sarthrum (Bitt.) Bitt. and Solanum, respectively. he occurrence of the same type of exine sculp- turing in Cyphomandra, however, argues against the use of this character to distinguish Cypho- mandra from Solanum. This same type of sculp- turing also has been reported for other genera related to Solanum (Basak, 1967) and is probably the general pollen type of the tribe Solaneae The pollen grains and seeds of S. allophyllum are much smaller than those of any species of Cyphomandra. The pollen dimensions of 5. allo- phyllum are comparable to some of the smaller grains reported for Solanum (Anderson & Gensel, 1976; Basak, 1967; Murry & Eshbaugh, 1971), and the size of the seeds falls within the range for Solanum (pers. obs.). Pollen or seed size has not been critically examined as a taxonomic character separating Cyphomandra and Solanum. small pollen and seeds of S. allophyllum may be connected with its small chromosome size. Bennett (1972) observed that genome size was correlated with pollen volume, seed weight, and minimum generation time in various species herbaceous plants. The association of small chro- mosome size with small pollen volume, seed weight, and short generation time in S. allophyllum may indicate that this correlation also holds in this species. Further observations are needed to ascer- tain whether these characteristics are correlated in other solanaceous species, and whether pollen and seed size may be used as indicators of chromosome size. Affinities of S. allophyllum within Solanum are problematic. This species is allied with two others, S. mapiriense Bitter from Bolivia and an unde- scribed species from Amazonian Peru (Bohs, in prep.). At present I know of no existing section of Solanum that accommodates these three species. They are perhaps best regarded as a new section of Solanum, as Bitter (1913) suggested. A taxo- nomic treatment of these three species and a con- sideration of their placement within Solanum will appear in a later paper. LITERATURE CITED ANDERSON, G. J. . G. GENSEL. 1976.

Beneath the hairs the testa very thin, stiffly papery, smooth, glossy, yellowish tan, longitudinally striate; the en- dosperm forming a leathery case around the em- bryo; embryo 1.8 cm long, straight, the cotyledons rather fleshly, ca. 314 times as long as the radicle, this thick, bent slightly. Distribution. Colombia, known only from high forest over white sand at the type locality on the Rio Caquetá. The specific epithet refers to the bifid, stout, curving fruit reminiscent of buffalo horns. Malouetia bubalina is most closely related to M. arborea (Vell.) Miers of eastern coastal Brazil, which also has stout fruits and seeds with an in- dumentum. But whereas the hairs on the seeds of M. arborea (Vell.) Miers are woolly and extend in all directions, those of M. bubalina are straight and directed toward the base of the follicle. The new species also differs by having much shorter pedicels and more ovate corolla lobes. 2. Malouetia molongo M. E. Endress, sp. nov. TYPE: Venezuela. T.F.

TICODENDRON: A NEW TREE FROM CENTRAL AMERICA Jorge Gómez-Laurito' and Luis D. Gómez P.? ABSTRACT Ticodendron incognitum is named as a new genus and species, and the taxonomic position of this tree is discussed. Despite many years of floristic research in var- ious Central American countries, new findings still surprise botanists. Such is the case of a tree, here described as a new genus and species, which has puzzled many scientists in the field and in herbaria and which has produced much correspondence and discussion. Based on studies of embryology, paly- nology, wood anatomy, and other features, a new family of dicots will be published soon for this genus.

Werckle (s.n., US No. 1010451) near San Cristóbal. The specific epithet refers to its Hamamelidean rela- tionships. e new genus and species of Hamamelidean affinities (Gómez-Laurito & Gómez, 1989) has prompted much discussion: a possible relationship to Urticales (e.g., Ulmaceae or Cecropiaceae) has been suggested. Dilleniales (Wolfe, 1989) and Ro- sales have also been proposed as possible orders for Ticodendron. For some time, placement in the Ulmaceae was favored and our genus does resemble genera of this family (e.g., Aphananthe Planchon), but its morphology excludes Ticodendron from subfamilies Ulmoideae or Celtidoideae. As in the Ulmaceous genus Zelkova Spach, Ticodendron has drupaceous fruits and somewhat distichous, pin- nately veined leaves, but has four hemitropous ovules, three of which abort very early in devel. opment. Leaf characteristics suggested to W. Bur- ger (pers. comm.) a relationship to the Cecropi- aceae, but our observations revealed a bicarpellate ovary and two well-differentiated and free stigmas, among other differences. The dry, hardened fruits bear a faint resemblance to those of Corylus L., and, when we first saw a vegetative specimen, we thought of Carpinus L., which reaches northern Nicaragua. Several genera of Hamamelidales (e.g., centron Oliver, Sinowilsonia Hemsley, Altingia Noronha, and others) show many of the morpho- logical characteristics of the new plant and suggest that its true affinities lie within this order, although its precise placement requires further study. he venation and marginal teeth of Ticodendron leaves have been compared and found somewhat similar to those of fossil Juglandaceae (Hickey, fide Raven, pers. comm.). Some botanists initially pro- posed Flacourtiaceae as the proper family. A possible relationship between Ticodendron and the Antillean Picrodendron Planchon, based on the similar appearance of the pistillate flowers, has been suggested (M. Grayum, pers. comm., 1987) but 7icodendron has simple leaves and strongly asymmetrical fruits. Further, its pollen grains are Tetra- unusually small and not of the Olfieldia-type, which occurs in the Euphorbiaceae, where most modern authors place Picrodendron (Hakki, 1985; Hay- den et al., 1984; Webster, 1975). Wood anatomy (Carlquist, in press) and reproductive morphology (Tobe, in press) point to Fagales. Ticodendron incognitum forms sparse stands or is found isolated in the montane evergreen forest of Central America. In Costa Rica, it usually grows from 900 to 2,300 m elevation associated with Aiouea costaricensis (Mez) Kostermans, Phoebe hammeliana W. Burger, Cedrela salvadorensis Standley, Eugenia lepidota Berg, and other species. macho and jaül nazareno (male alder alder). Both names recall the alderlike habit of Ticodendron and the purplish tinge of fresh cuts in most of the trees. Also, it is called duraznillo and candelillo morado. The wood is used as fire- wood. It is fine-grained, dries a pale rosy-brown, takes a high polish, and is harder than that of Alnus. LrrERATURE CITED CaRLQUIST, S. Wood and bark anatomy of Ticodendron; comments on relationships.

A SECOND SPECIES OF THE AMPHI-ATLANTIC GENUS ALONSOA (SCROPHULARIACEAE) IN SOUTH AFRICA! Kim E. su Steiner ABSTRACT A second species of the predominantly South American genus Alonsoa has been found to occur in South Africa, cies in having oil-secreting trichomes in shallow corolla sacs and from the other S species in its annual habit, dilated filaments, and acuminate, bilobe d stigma. Flowers of Alonsoa unilabiata are self- compatible, but are usually out-crossed by Rediviva (Melittidae) oil-collecting bees. Differences between Alonsoa and Niascia are discussed. Alonsoa Ruiz & Pavón is a small genus of ap- proximately 16 species that until recently was be- lieved to be restricted to the New World (Edwin, 1971; Hilliard & Burtt, 1984; Roux, 1986). It is concentrated primarily in the Peruvian Andes of South America but ranges north through Central America to Mexico and south to Chile and Bolivia; it also occurs in the Cape floristic region of South Africa. Alonsoa is one of seven genera that Bentham (1876) placed in the Hemimeridae, the others being Diascia, Diclis, Hemimeris, Colpias, and Angelonia. Since the American genus An- elonia is now placed in its own tribe Angelonieae (Pennell, 1920; Barringer, 1983, 1985), the Hem- imeridae, with the exception of most species of Alonsoa, are basically restricted to southern Af- Nemesia, ca. The first Alonsoa (A. peduncularis (Kunze) Wettstein) species discovered in Africa was col- lected by Zeyher (3485) in the late 1830s from woody gorges around Uitenhage in the eastern Cape. The original description (Kunze, 1842) was prepared from cultivated plants at the Leipzig bo- tanical garden. The source of that seed was Leh- mann of Hamburg who obtained it from someone in South Africa. The original source is uncertain, but, due to the rarity of this plant, it may well have come from Zeyher’s collection. No subse- quent collections of this taxon were made until its discovery at a second locality in 1985 (Roux, 1986). Since this second site is far removed from areas 2 past or present cultivation, and since no known South American species have corolla sacs, Ben- tham’ s (1876) suggestion that the original speci- men collected by Zeyher was naturalized from South America is highly unlikely. Evidently Bentham’s reluctance to accept Alonsoa as indigenous to South Africa was due to the unusual amphi-Atlantic dis- tribution that this would represent. Out of a combined total of about 4,500 genera occurring in Africa (including Madagascar) and South America, a, 115 (2.6%), in- cluding Alonsoa, are restricted to these subconti- nents (Thorne, 1973; Hilliard " Burt 1984). O these, only seven (0.2% of the full total) occur in the Cape flora of South Africa. Among genera shared between South Africa and America, Alon- soa is the only genus presently centered in the Andes. Except for a few widespread genera (e.g., ! I thank J. P.

This and other evidence led Ra- ven & Axelrod (1974) to suggest that the Scroph- ulariaceae probably did not exist when the two subcontinents were close together. Thus, Alonsoa must have reached Africa subsequently by long distance dispersal In America, Alonsoa is characterized by race- mose inflorescences, resupinate flowers with the American .

South African members of the genus are additionally character- ized by two shallow yellow sacs in the gamopetalous portion of the corolla at the base of the lateral corolla lobes (Figs. 1-4, 5A, B). These sacs are densely packed with oil-secreting trichomes (Hil- liard & Burtt, 1984; Roux, 1986; Steiner, pers. obs.). My current research on the annual Diascia cm. species from the western Cape has revealed that a second species of Alonsoa has been incorrectly classified as Diascia unilabiata (Linn. f. th The presence of a second Alonsoa species in South Africa strengthens the unusual amphi-Atlantic con- nection within the genus and warrants an exami- nation of the distinction between Alonsoa and Diascia in general, and the taxonomic history, variation, and reproductive biology of Alonsoa uni- labiata (Linn. f.) Steudel in particular. HABIT AND HABITAT Alonsoa unilabiata is a winter-flowering (July- October) annual herb with simple to dissected leaves and pink to orangish pink resupinate flowers with dark purple-maroon centers. Contrasting with the dark center is a yellow translucent window or sac at the base of each lateral corolla lobe. Alonsoa unilabiata occurs from near the west coast of South Africa (Elands Bay and Lamberts Bay), where it is found in loose sands of old sta- bilized dunes at about 100-200 m, northeast to the escarpment of the Bokkeveld Mountains (Nieuwoudtville area), and along the Roggeveld escarpment from Calvinia south to the northwest- ern edge of the Little Karoo (Konstabel and Twee- 1154 Annals of the Missouri Botanical Garden FIGURE 5.

On the escarpments of the Bokkeveld and Roggeveld, these plants grow primarily in sandy to clay loam soils derived from shales, except around Nieuwoudtville where they occur on heavy doleritic clays. Drége collected 4. unilabiata from the southwestern Cape near Cape Town in 1836, no recent collections have been made from "m area. Alonsoa peduncularis, in contrast, is known from only two localities in the southern and eastern Cape floristic region (Fig. ere appear to be lires fairly recognizable ecotypes of A. unilabiata associated primarily with different soil types. The differences between the ecotypes, involving mainly extent of leaf dissection and corolla sac shape, are not, however, great enough to warrant taxonomic recognition. DISTINCTIONS BETWEEN DIASCIA AND ALONSOA Corolla morphology of South American and South African species of Alonsoa is remarkably similar (Figs. 1-5A, 7). Most obvious is the resupination which places the enlarged morphologically lower lip in an upright position. Resupination was over- i and all subsequent botanists except Diels (1897), presumably because this character is obscured in Volume 76, Number 4 1989 Steiner 1155 Alonsoa in South Africa FicunE 6. Distribution of Alonsoa unilabiata (solid rica pressed material. Diascia species do not have re- supinate flowers. Coupled with the rather strange appearance of the corolla caused by resupination in Alonsoa is the complete split in the corolla between the lower (morphologically upper) lobes (Fig. 5B), a character that Kunze (1842; in Hilliard & Burtt, 1984) erroneously attributed solely to Alonsoa peduncularis (as Schistanthe peduncu- laris). This condition is also found in A. unilabiata, as well as New World species A. meridionalis vd Kunze and others (pers. obs.; Edwin, 1971). T Diascia corolla always has a short but distinct us (i.e., gamopetalous portion) without a split. Another distinction between Alonsoa and Dias- FIGURE 7. Flower close-up of Alonsoa meridionalis subsp. Ds from El Angel, Ecuador circles) and Alonsoa peduncularis (star circles) in South cia is the form of the androecium. In Diascia (and in the related /Vemesia and Diclis) the anterior lower) filaments twist around the base of the pos- — terior (upper) filaments, causing the upper part of the anterior stamens to be placed in a posterior position and the posterior stamens to appear in the anterior position (Hilliard & Burtt, 1984). No such twisting of the filaments occurs in Alonsoa, al- though a similar result without twisting is achieved in A. pe (morphologically upper) stamens are situated above duncularis, where the anthers of the lower the anthers of the upper (morphologically lower) stamens. In 4. meridionalis, the stamens are up- right; in A. unilabiata (Fig. 5C) and A. pedun- cularis they project downward. This downward orientation in 4. unilabiata is caused by the turn- ing under of the lower (morphologically upper) rim of the corolla just above the point of filament at- tachment. Alonsoa unilabiata is set apart from all other Alonsoa species by its strongly dilated fila- ments (Fig. 5C- Seed uote has further distinguishes Alonsoa from Diascia. As shown in Figures 8-11, 4. uni- labiata, A. peduncularis, and other Alonsoa species have wingless, oblong to elliptic seeds, usu- ally with longitudinal straight (or undulate in A; unilabiata) furrows (Edwin, 1971). Diascia species have dorsiventrally flattened embryos and usually have elaborate wings or cuplike extensions on the seed coats. The pollen of 4. unilabiata and A. peduncularis is tricolpate in contrast with the hexa- 1156 Annals of the Missouri Botanical Garden Scanning electron micrographs of Alonsoa seeds. 10. 4. peduncularis. — unilabiata from Calvinia District. — 10. 4. to octacolpate grains of all examined Diascia species. Diascia and Alonsoa are distinguished in Ta ble 1. POLLINATION AND BREEDING SYSTEM The major difference between South African and South American Alonsoa species is the presence in the former of a pair of shallow corolla sacs (Figs. 1-4, 5A, B) containing a dense patch of oil-se- creting trichomes (trichome elaiophores). These tri- ~ FIGURE 12. Trichome elaiophore from the corolla sac of Alonsoa unilabiata. Scale line = 15 un -8. unilabiata from Elands Bay.— 9. A. A. meitduonilis from Peru.

The dark central portion of the corolla as well as the yellow sacs are ultraviolet absorptive and con- trast with the UV reflective corolla lobes (Steiner, pers. obs.). The presence of an ultraviolet absorp- tive region is common in oil-secreting species of Diascia and Hemimeris and appears to help orient the bee on the flower (Steiner, in press, pers. obs.). Specialized scraping and absorptive setae on the forelegs of the Rediviva pollinators facilitate ex- traction of the oil, which is transferred to the hind legs and carried back to the nest (Whitehead & Steiner, 1985; Steiner & Whitehead, 1988; Buch- mann, 1988). While probing for oil with its fore- legs, the bee’s abdomen curls into the cradle formed by the filaments, causing the anthers to rub against and deposit pollen on the upper tergites. Pollen is deposited from the abdomen onto the stigma of the next flower as the bee repeats this process. The two Rediviva species at Elands Bay do not depend solely on 4. unilabiata for oil, but also visit at least three other oil-producing species in- cluding Hemimeris sabulosa L.f. and two unde- scribed Diascia species. On the Roggeveld es- carpment, with the exception of the Nieuwoudtville area, 4. unilabiata is pollinated almost exclusively by Rediviva *alonsoae." Even more unusual, however, is the apparent restriction of this bee to the flowers of 4. unilabiata for oil, despite the co- occurrence of other oil-producing species at each site. This bee is the only one of 16 western Cape Rediviva species that is restricted to a single oil host plant (Steiner & Whitehead, pers. obs.). Pollinator observations on other Alonsoa species are lacking. Alonsoa peduncularis occurs sym- patrically with Diascia patens (Thunb.) Fourcade and may share the same Rediviva “lepidos” pol- linator that collects oil from and pollinates that species, while New World species of Alonsoa, all of which lack oil-secreting trichomes, are probably pollinated by pollen-collecting bees. Many of the American species have large sturdy apically de- hiscing anthers that form a cone around the style similar to that found in Solanum. These species are probably **buzz" pollinated (Buchmann, 1983) by large Bombus (Apidae) or Centris (Anthopho- ridae) bees. The presence of shallow yellow corolla sacs in some annual Diascia species (D. capensis (L.) Britten, D. diffusa (Thunb.) Benth., D. cardiose- pala Hiern, D. elongata Benth. et al.) probably accounts for the past confusion between Alonsoa unilabiata and Diascia. It is unlikely, however, that the presence of these sacs is indicative of a close relationship between Diascia and Alonsoa (Steiner, unpublished). Instead, it probably indi- cates a convergence based on adaptation to polli- nation by oil-collecting bees (Whitehead & Steiner, 1985; Steiner & Whitehead, 1988). Such unre- lated parallel evolution of oil secretion has occurred numerous times in families as disparate as Orchi- daceae, Iridaceae, Malphighiaceae, Krameriaceae, Scrophulariaceae, and Primulaceae; in unrelated orchid genera such as Oncidium and Disperis; and among unrelated Scrophulariaceae, such as Cal- ceolaria, Bowkeria, and Diascia (Vogel, 1974, 1986; Simpson & Neff, 1981, 1983; Steiner, 1987). Alonsoa unilabiata is self-compatible, as are other species in the genus, including 4. pedun- cularis (Roux, 1986) and A. meridionalis (pers. obs.). Both of these last-mentioned species readily self-pollinate, and 4. peduncularis can produce cleistogamous flowers under certain circumstances ~ pers. obs.). Flowers of Alonsoa unilabiata, how- ever, self-pollinate only occasionally because of the spatial separation between anthers and stigma. Alonsoa unilabiata is most closely allied to Alonsoa peduncularis, with which it shares the presence of corolla sacs containing trichome elaio- phores, characters that must have evolved in Africa in conjunction with Rediviva oil-collecting bees. The annual habit, curved and dilated filaments, and acuminate two-lobed stigma, however, are all specialized features that set 4. unilabiata apart from A. peduncularis and the South American species. SYNONYMY AND DESCRIPTION Linnaeus f. (1781), Thunberg (1784), and Ben- tham (1846, 1876) all failed to realize that Alonsoa unilabiata (Linn. f.) Steudel has resupinate flowers. As a result, Diels (1897) described a new species — Diascia nutans Diels) for a collection of A. uni- labiata from the Hantam Mountains near Calvinia. Discussing the resupinate corolla in his species, Diels stated that i to the same result as resupination of the Alonsoa “evidently this development led 1158 Annals of the Missouri Botanical Garden corolla, in fact the convergence developed so far that without the pits in the throat of the corolla, our species [D. nutans] would have to be placed in Alonsoa.” The type of D. nutans was destroyed in Berlin, but the description and recent collections from the same locality (Steiner 759) suggest that Diel's plant must have been 4. unilabiata (Linn. f.) Steudel. When Bentham (1836) described D. heteran- dra he had not seen the type of Alonsoa unilabiata nor did he see it prior to his treatment of Diascia in De Candolle's Prodromus (p. 17, 1846). This may explain why he described Drége's collection as a new species in the first instance and why he retained it in his later publication. One of the char- acters used by Bentham to MEUS. D. heter- andra was the presence of st . Judging from the poor preservation of the type as well as the relative ease with which anthers become de- tached in fresh material, it is likely that the missing anthers fell off during preparation and subsequent handling, since the specimen matches 4. unila- biata in all other respects. The type location for Diascia heterandra Benth., between Blouberg and Tygerberg, is considerably south of the main west coast distribution of 4 unilabiata. Habitats near the type locality, how- ever, are similar to those found around Elands Bay, where Alonsoa unilabiata can be locally common. The area between Blouberg and Tygerberg has been dramatically altered by the spread of urban- ization and alien acacias, hence 4. unilabiata is probably no longer there. Diascia dissecta Hiern is simply a variant of A. unilabiata related to growth conditions. Its tall and spindly habit and more narrowly dissected leaves are typical of plants along the Roggeveld escarp- ment that grow up through shrubs. Alonsoa unilabiata (Linn. f.) Steudel, Nomencl. 840.

The species is named for the distinctive wormlike markings on the proximal and distal faces of the megaspores. Isoetes vermiculata is a distinctive element of the /soetes flora of northern South America. When fertile, it is most easily identified by its large, ru- gulate to subretate megaspores and depressed-ob- ovate sporangia with nearly complete vela. It can be identified vegetatively by a combination of the triquetrous (three-sided, with rounded angles) subu- la, depressed-ovate, auriculate ligular cushion, and absence of a well-developed labium. The only other species of /soetes known from this region of Ven- ezuela is /. triangula, a lowland, seasonal species having a trigonal (three-sided with sharp angles) subula, large labium, and pustulate megaspores, and not having a velum. Not enough is known about /. vermiculata to judge affinities with other species in the genus. The triquetrous subulae and rugulate to subretate mega- spores of /. vermiculata are, however, similar to 1989. Volume 76, Number 4 Notes 1161 1989 = FIGURE 1.

A NEW SPECIES OF CLITORIA (LEGUMINOSAE) FROM VENEZUELAN GUAYANA Two recent collections of a distinctive species of Clitoria L. (Leguminosae) were discovered while preparing a treatment of the genus for the Flora of the Venezuelan Guayana. This species is as- signed to subg. Bractearia (Mart. ex Benth.) Fantz sect. Brachycalyx Fantz. Clitoria comprises 60 species distributed pri- marily within the pantropical-subtropical belt; 49 species are native to the Neotropics. The genus is characterized by showy, resupinate, papilionaceous flowers; infundibular calyx with persistent brac- teoles at the base; persistent stipules and stipels; and stalked ovaries with a geniculate, bearded style. Members commonly bear a pubescence of micro- scopic uncinate (hooked) trichomes best viewed at 20-30%. Fantz (1979) circumscribed sect. Brachycalyx and in 1980 added three new species. Members are characterized by short tubular calyces with minute lobes, inflorescences cauliflorous emerging from denuded nodes preceding the leaves, erect habits (trees or shrubs), and fruits that become weakly convex around the seeds and that are con- spicuously depressed transversely between the seeds. Species of this section are distributed from Guyana to central Panama to Ecuador with isolated col- lections of Clitoria glaberrima Pitt. collected as far north as southern Mexico.

A NEW SPECIES OF CABOMBA (CABOMBACEAE) FROM TROPICAL AMERICA The genus Cabomba is restricted to the Western Hemisphere, ranging from the eastern United States through Central America and the Caribbean to Argentina. Species of this genus are quite similar in habit, and few morphological characters are useful for distinguishing among them. The only complete taxonomic treatment of Cabomba, by Norman Fassett (1953), separated species primar- ily using characteristics of the perianth and leaf segments. From my fieldwork in tropical America and an examination of much of the material that has been collected from this region, some taxo- nomically significant characters not employed by Fassett have been discovered. Such characters are the number of leaves per node, stamen number, and seed size and shape. Other differences among taxa for the characters used by Fassett have also been noted. In applying this enhanced scrutiny to the ma- terial included by Fassett in C. piauhyensis Gard- ner (= C. furcata'), I have become convinced of the existence of two distinct taxa within this entity. Typical C. piauhyensis always has whorled leaves at most or all nodes, commonly six (occasionally four or five) stamens, and subglobose seeds. This has been verified using an isotype of Gardner's original collection (Gardner 2478 US) and is also readily apparent from the original illustration (Gardner, 1844). The distribution of C. piauhyen- sis (C. furcata) includes Brazil, northern Bolivia, Venezuela, eastern Colombia, the Guianas, Trini- dad, and outlying populations are known from Cuba and Costa Rica as well. A second taxon, which Fassett failed to recognize, has opposite leaves, often three stamens (sometimes four or five or rarely six), and slightly larger subglobose to oval seeds. This taxon occurs from Honduras to western Ecuador and northern Venezuela and in the Great- er Antilles. The principal area of sympatry for the two species is northern Venezuela. The second taxon is here described, and a key to all members of Cabomba that occur within its range is provided. Cabomba haynesii Wiersema, sp. nov. TYPE: Panama.

A NEW SPECIES OF HYPTIS (LAMIACEAE) FROM THE VENEZUELAN GUAYANA While examining collections of Lamiaceae for the Flora of the Venezuelan Guayana, | encoun- tered a single gathering of a Hyptis species that was unfamiliar to me. It was surprising to find a new Hyptis species at an altitude of 120-150 m in northern South America. Although clearly belonging to sect. Hyptis, it differs from all other known species in its elongate, interrupted, pseudospicate inflorescences com- posed of small sessile capitula and situated in the axils of much-reduced bracts. The new species is also remarkable for its almost sessile leaves, the petiole apparently never more than 2 mm long. In this respect, it recalls H. vilis Kunth & Bouche, from Central America and northern Venezuela but differs in floral characters and in leaf shape, and by having sessile rather than long-pedunculate ca- pitula. The lack of a ring of hairs in the calyx tube places H. guanchezii in subsect. Marrubiastrae Benth., along with H. parkeri Benth., which is also found in the Territorio Federal Amazonas. Hyptis guanchezii is named for the collector and discoverer Francisco Guánchez. Hyptis guanchezii R. Harley, sp. nov. TYPE: Venezuela. Territorio Federal Amazonas: Depto.

Inflorescence spi- ciform, 10-15 em long, composed of opposite ses- sile capitula in the axils of inconspicuous bracts, the lower internodes usually 5-6 cm long. Bracts up to 4-6 mm long (the upper bracts shorter), lanceolate to ovate-acuminate, with broadened base and somewhat recurved margin, midrib prominent abaxially. Capitula 10-12 mm diam., with an in- volucre of narrowly lanceolate, curved bracteoles up to 5 X 1 mm, these glabrous with the midrib prominent beneath. Flowers subsessile, surrounded at base by dense tuft of long, silky, white (pale brown in herbarium material) hairs.

NEW COMBINATIONS IN SORGHASTRUM (POACEAE: ANDROPOGONEAE) Nash (1901:71) separated Sorghastrum from Sorghum Moench on the basis of the reduction of the pedicellate spikelets to simple pedicels in Sor- ghastrum. Morphological, anatomical, and cyto- logical data (Davila, in prep.) support Nash's con- clusion and reinforce the generic recognition of Sorghastrum. Davila (1988) recognized 15 Amer- ican and two African species of Sorghastrum. Two new combinations in this genus are presented be- low. Sorghastrum balansae (Hackel) Davila, comb. nov.

PASSIFLORA MALLETII, A NEW SPECIES IN SECTION DECALOBA (PASSIFLORACEAE) FROM MESOAMERICA A number of undescribed species of passion- flower have been found during a revision of the Passifloraceae for the Flora Mesoamericana proj- ect (in press); most of them are in the small-flowered subgenus Plectostemma Masters.

Habitat and distribution. The one field ob- servation by Mallet and the three collections are from 300—750 m at edges of tropical wet forest and premontane wet forest, within 25 km of each other in central Panama. The label on the type describes the locality as “Pacific slope near divide, rich wet forest.” Name. The specific epithet honors the ecol- ogist Dr. James Mallet, whose specialty is the Heli- coniine butterflies that feed on Passifloraceae. He observed this species along the Llano—Carti road in March 1982, made field notes about the plant, sent living collections to the University of Texas at Austin for study (which died), and pointed out (in litt.) that it was apparently undescribed. He has made numerous and detailed observations on the Passifloraceae and realized that a number of species he encountered were new. By kindly allowing free access to his field books, his detailed notes have enhanced the accuracy of the revision for Flora esoamericana and contributed much to our un- derstanding of Passiflora.

Juss., P. rugosis- rona and plicate operculum, small free bracts, nar- — sima Killip, P. porphyretica Masters, and two new 1174 Annals of the Missouri Botanical Garden species from Mexico. From these it is remarkably distinguished by its mostly unlobed, sharply pointed leaves, an evidently derived condition. Mallet's field notes describe the stem as strongly flattened, suggestive of an unusual phyllotaxy for the family, ut the dried specimens of the other collectors appear to be subangulate to partially flattened. The phyllotaxy is not clear because of deformation of the stems in drying; both 7; and /j are known in the related species of this group. The flowers of the new species are notable for their short androgynophore and very reduced pet- als. The sparsely setulose operculum is also dis- tinctive since the floral parts are only rarely pu- bescent in this genus. The peduncles are uniflorous and the flowers are generally crowded on deter- minate axillary branches, much like its close rel- ative P. porphyretica. The seeds of nearly all of the species of sect. Decaloba are probably bird dispersed, but obser- vations are few. The label on J. 5. Miller et al. 851 notes "fruit green and being eaten by tou- canettes." I believe the mature fruits to be purplish black because in this collection the pericarps turned black during the process of preparing the specimen, a phenomenon commonly seen with nearly mature fruits in this section. In most species of Passiflora the seeds and arils mature before the pericarp changes color (pers. obs.). It thus appears that the irds were eating submature fruit, probably with sweet mature arils. The Missouri Botanical Garden, with a grant from the Jessie Smith Noyes Foundation, gener- ously funded my postdoctoral research. John Myers prepared the illustration. —John M.

Louis, A NEW COMBINATION IN OCOTEA (LAURACEAE) Nees (1836) described Nectandra arnottiana in his Systema Laurinarum and cited only a spec- imen from the Arnott Herbarium which is now incorporated in the Herbarium of the Royal Botanic Garden, Edinburgh (E). This specimen has not been seen by later botanists working on Lauraceae, who treated the name incorrectly. Meissner (1864) treated N. arnottiana as a variety of Nectandra laurel Nees and stated that he did so only guided by Nees's description. Mez (1889) accepted N. arnottiana as a valid species and treated Pleuro- thyrium chrysothyrsus Meissner as a synonym of it. He cited only Mathews 3031 (K, BM), the type of P. chrysothyrsus, under N. arnottiana and obviously had not seen the specimen from the Ar- nott Herbarium. I have now seen the Edinburgh specimen annotated by Nees as N. arnottiana. This specimen is Mathews 1429. Meissner (1864) rec- ognized a duplicate of Mathews 1429 in Kew as an undescribed species and made it the type of his Pleurothyrium ferrugineum, a species up to now known as Ocotea ferruginea (Meissner) Mez. But because the Nees epithet has priority, I transfer it to Ocotea and present the synonymy for the re- sulting combination, with the Meissner name in synonymy.

Excluded from the synonymy is Nectandra ar- nottiana sensu Mez, non Nees, Jahrb. Bot. Garten Berlin 5: 402, 1889. Mez based his description on Mathews 3031, the only collection cited, and his description of leaves and flowers does not apply to Ocotea arnottiana. Ocotea arnottiana is known to me from Andean cloud forests at 2,000-3,000 m in northern Peru Bernardi (1975) placed Ocotea steyermarkiana Allen in synonymy under O. ferruginea and identified several collections from and southern Ecuador. Venezuelan Guayana as O. ferruginea. However, I consider these Venezuelan collections distinct from O. arnottiana; monodaphne steyermarkiana (Allen) van der their correct name is Rhodoste- Werff. Similar coriaceous leaves with raised retic- ulation and a dense tomentum on the lower leaf surface, which misled Bernardi, occur in several unrelated, montane species of Lauraceae and are probably a habitat adaptation. Meissner (1864) already noted the strong similarity between **Pleu- rothyrium ferrugineum and Persea ferruginea HBK; and an as yet un- described species of Ocotea (not related to O. ar- EE) (= Ocotea arnottiana) nottiana) from high elevation cloud forests in Ec- uador and Colombia also has these characteristics.

SISYMBRIUM AREQUIPANUM (BRASSICACEAE), A NEW SPECIES FROM PERU The Brassicaceae (Cruciferae) of Peru were treated by Macbride (1938) more than half a cen- tury ago. changes have since been proposed (see for example, Al-Shehbaz, 1989a, b; Khanna & Rollins, 1965). The family as represented in South America needs to be revised, and many undescribed taxa, partic- any new taxa and nomenclatural ularly in the genera Draba L., Lepidium L., and Sisymbrium L., should be accounted for. The pres- ent writer is presently working on Draba in South America as a first step toward achieving that goal. Sisymbrium arequipanum Al- Shehbaz, named endemic, is somewhat isolated morpho- logically from all of the Peruvian species of Sisym- brium. lt is easily distinguished by having narrowly linear-lanceolate, remotely dentate basal leaves, auriculate linear-lanceolate cauline leaves, a few small flowers, and straight, terete fruits on short, ascending, straight pedicels. The species resembles superficially members of Arabis L., but this genus does not occur anywhere in Central and South America, and it always has flattened fruits. digi WO Mus Al-Shehbaz, sp. nov.

Instituto de Botánica Agrícola, REDISCOVERY OF TETRAMOLOPIUM ARENARIUM SUBSP. ARENARIUM VAR. ARENARIUM (ASTERACEAE: ASTEREAE) ON THE POHAKULOA TRAINING AREA, HAWAII The initial step in the U.S. Army's Land Con- dition Trend Analysis Program (LCTA) is to con- duct a comprehensive floristic and vegetation in- ventory of each installation. One of the first group of installations to be inventoried was the Pohakuloa Training Area (PTA) on the Island of Hawaii, Ha- waii (Fig. 1). Pohakuloa Training Area is a 44,100- ha area located in the saddle between Mauna Loa and Mauna Kea. Approximately half of the in- stallation is ordnance impact area. Because of the rough terrain and inaccessibility of much of the area, only about 4,100 ha are used for infantry, artillery, and tracked-vehicle maneuvers. Three endangered plant species have been iden- tified previously from PTA (Herbst & Fay, 1979): Haplostachys haplostachya (A. Gray) St. John var. angustifolia (Sherff) St. John (Lamiaceae), Stenogyne angustifolia A. Gray var. angustifolia (Lamiaceae), and Lipochaeta venosa Sherff (As- teraceae). The species of Lamiaceae were thought to be extinct until their rediscovery on PTA (Ay- ensu & DeFilipps, 1978; Herbst & Fay, 1979). All three of these species occur in a designated endangered plants habitat (approximately 1,600 ha) on the northwest side of PTA within Kipuka Kalawamauna (Fig. 1). This kipuka is a vegetated older lava flow isolated by newer, sparsely vege- tated, or barren lava flows. The elevation of the area is approximately 1,545 m. The kipuka re- ceives about 380 mm of precipitation annually. During the LCTA survey of the vegetation at PTA, Tetramolopium arenarium (A. Gray) Hil- lebr. subsp. arenarium var. arenarium (Astera- ceae: Astereae) was collected by P. Douglas (Doug- las 3191) (Fig. 2). Ayensu & DeFilipps (1978) and Lowery (1986) reported this taxon as presum- ably extinct because no collections had been made since the late 1800s. The only previously known localities for this taxon were Puu Hualalai and Nohonao Hae (near Waimea) on Hawaii and Kula, East Maui (Lowery, 1986). A botanical survey conducted in 1977 as supporting documentation for an environmental impact statement for PTA listed T. arenarium (Lawrence Hirai, pers. comm.). We have been unable to locate any voucher spec- imens for this reported collection. Douglas 3191 was collected in the endangered plants habitat, near the three endangered plant species. The population of Tetramolopium covers an area about 200 m by 60 m and is bisected by an unpaved road. One part of the population grows about 20 m east of the road. When last observed, it consisted of 33 robust individuals. The other portion, with 81 adult plants and 14 juvenile or seedling plants, occurs approximately 80 m west of the road. Consequently, the two portions are about 10 m apart. Fifteen dead individuals were found in the larger portion of the population. The cause of death of these plants is unknown. The occurrence of juvenile or seedling plants indicates that viable seed is being produced and that envi- ronmental conditions necessary for seed germina- tion and seedling establishment occur periodically. Mature plants were observed flowering in January, April, and August. The collection was made in a shrubland domi- nated by Dodonaea viscosa Jacq., Dubautia lin- earis (Gaud.) D. Keck, and Sophora chrysophylla (Salisb.) Seem. A weedy, introduced grass (Pen- nisetum setaceum (Forssk.) Chiov.) is aggressively expanding into the area. The Tetramolopium pop- ulation occurs on a mesic ridge that runs west- northwest. The soil type at this site is rockland (rRO) (USDA, 1973). Tetramolopium arenarium is a member of sect. Sandwicense Lowery, which is composed of gy- nomonoecious, upright shrubs with corymbose- paniculate heads, narrowly funnelform disk corol- las, and fewer than 15 disk florets per head (Lowery & Crawford, 1985; Lowery, 1986).

Gray) Hillebr., T. conyzoides (A. Gray) Hillebr., and 7. lepidotum (Less.) Sherff. Of the four species in the sect. Sand- wicense, two have been considered extinct: T. are- narium and T. conyzoides (Ayensu & DeFilipps, 1978; Lowery, 1986). The other two species have extinct infraspecific taxa (Lowery, 1986). Tetramolopium consanguineum never has hir- sute or pilose leaves (Douglas 3191 has densely and evenly hirsute leaves). Tetramolopium cony- zoides has 1-3 disk florets per head (Douglas 3191 has 5-9 disk florets per head). Tetramolo- pium lepidotum has glandular punctate leaves (Douglas 3191 has glandular but not punctate 1184 Annals of the Missouri Botanical Garden FIGURE 2.

(Scale in deci- meters.) leaves). The only other member of sect. Sandwi- cense that occurs on PTA is Tetramolopium con- sanguineum. Tetramolopium arenarium is composed of two subspecies, both presumably extinct: subsp. are- narium on Hawaii and Maui and subsp. laxum on Maui (Lowery, 1986). Tetramolopium arenarium subsp. laxum has open, lax inflorescences, flexuous pedicels, granuliferous-glandular achenes, and fo- liage that retains its yellow-green color when dried. In contrast, T. arenarium subsp. arenarium has compact inflorescences, densely strigose achenes, nonflexuous pedicels, and brown foliage upon drying. Douglas 3191 has compact capitula, densely stri- gose achenes, nonflexuous pedicels, and brown dried foliage. Tetramolopium arenarium subsp. arenarium is separated into two varieties: var. arenarium and var. confertum. Tetramolopium arenarium subsp. arenarium var. confertum has dentate leaf mar- gins, and involucres 4-6 mm wide and 2-3 mm long. Tetramolopium arenarium subsp. arenar- ium var. arenarium has entire leaf margins, and involucres 6-9 mm wide and 3-5 mm long. Doug- las 3191 has entire leaves and involucres that are 6—7 mm wide and 4-5 mm long. We verified our collection by comparing it with two specimens of 7. arenarium subsp. arenarium var. arenarium at the U.S. National Herbarium (US): Mann & Brigham 519, collected at Puu Hualalai; and Hillebrand 319, which has no lo- cality information. Both of these specimens were annotated by Lowery (1986) as T. arenarium subsp. arenarium var. arenarium. Lowery (1986) stated the lectotype for this taxon was “Hawaiian Islands: Hawaii: 1840, U.S. Exploring Expedition (US!, mixed collection with isotype of T. arenarium subsp. laxum).” The staff at US could not locate nor has any record of this specimen; thus, we were unable to compare our specimen with the lectotype. Tetramolopium arenarium subsp. arenarium var. arenarium has no federal or state protection, because it has been listed as extinct by the U.S. Fish and Wildlife Service, Office of Endangered dp pin l (Andy Robinson, pers. comm.). The U.S. Army, however, has begun a protection program for this taxon at PTA. Herbst & Fay (1979) reported that grazing and browsing by feral animals, cutting for camouflage by military units, trampling by foot traffic or ve- hicles, and accidental fires set by hunters and/or military ordnances may adversely affect the three endangered plant species found at PTA. Our ob- servations indicate that the most likely threats to the endangered plant species and the Tetramolo- pium arenarium population are from feral animals, fire, and competition from invading, introduced plants. We have observed numerous feral sheep, goats, and hogs in the endangered plants habitat. Also, the area has been burned (date unknown). We have not observed off-road vehicular traffic, foot traffic, or cutting of vegetation for camouflage. Fencing, removal of all feral animals, reduced use of the area for training, and continued efforts by the Army to control fires may help protect these plants. We are researching the ecology and population biology of the endangered species and Tetramo- lopium arenarium with funding from the U.S. Army. Propagation of the species is being inves- tigated as a means of ensuring its survival. This research was funded by the U.S. Army Corps of Engineers, Engineering & Housing Sup- port Center (CEHSC-FN), Donald M. Bandel, Chief of Cultural and Natural Resources.

MISCELLANEOUS CHROMOSOME COUNTS IN ASTERACEAE, BIGNONIACEAE, PROTEACEAE, AND FABACEAE Since the publication of my review of the chro- mosome cytology of the Fabaceae (Goldblatt, 1981a) and the documentation of the original chro- mosome counts cited therein (Goldblatt, 1981b), I have made several more counts in the family. These are reported here with associated collection data (Table 1). Most of the counts are particularly note- worthy as they are either the first records for genera or the first for species. Counts are also reported for species of Astera- ceae, Bignoniaceae, and Proteaceae. The signifi- cance of the counts in relation to the existing cy- tological record is briefly discussed for each species. MATERIAL AND METHODS All counts were made from root tips of germi- nating seeds, grown in the greenhouse. All seeds were collected in the wild for this study. Tips were harvested in midmorning and pretreated in either 0.001 M aqueous hydroxyquinoline for 6-8 hr. at refrigerator temperature or in saturated aqueous M-bromonaphthalene for 4 hr. at room tempera- ture. After rinsing in tap water, the tips were fixed for 2-3 min. in 3: 1 absolute ethanol: glacial acetic acid, rinsed again in tap water, and then hydrolyzed in 10% HCI for 6 minutes at 60°C. Root apices were squashed in FLP orcein (Jackson, 1975). The species studied and collection data are listed in Table 1, in which the diploid numbers are pre- sented. DISCUSSION ASTERACEAE Of the estimated 48 species of the Old World and predominantly African Dicoma (tribe Muti- sieae), only an Indian species, D. tomentosa Cass., has been counted, Bhandari & Singh (1977) having reported 2n = 22. The report here for the southern African D. schinzii provides additional support for assuming a base number of x — 11 for the genus, although x — 9 is almost certainly basic for the tribe Mutisieae as well as for the entire family (Raven, 1975; Goldblatt, 1987). PROTEACEAE Already counted as Aulax cneorum, the record here of 2n = 22 in A. umbellata, confirms de Vos's (1943) report of n = 11 in Aulax. Other African Proteoideae have x — 12, except Leuca- dendron, which has x = 13 (de Vos, 1943; Wil- liams, 1972). 4ulax and Leucadendron are the only dioecious African Proteoideae, and the kary- ological data support the contention, based on other criteria (Rourke, 1987), that dioecism evolved in- dependently in the two genera and that they are not closely allied.

FABACEAE The count for Zenia insignis, a taxonomically isolated and apparently primitive member of Caes- alpinieae—Cassieae, accords with the putatively ba- sic chromosome number for the tribe, x = 14 (Goldblatt, 198 1a). In Papilionoideae, 2n = 20 in the monotypic Graziodendron is consistent with other numbers recorded for Dalbergieae, including the closely re- lated genus Andira (Goldblatt, 1981a). Pterocar- pus, also considered closely related (de Lima, 1983) probably has x = 11, but at least two species also have n = 10 (Goldblatt, 1981a).

Standley & Schubert Mexico, near Vera Cruz, Norman 801 (F, GH) with the presumed base number for Tephrosieae, = 11 (Goldblatt, 19812). In the previously un- counted genus Poissonia (tribe Robinieae), P. hy- poleuca has 2n — 32, and this species appears to be oe Base number in Robinieae is either = nies or 10, but dysploidy is evident in the tribe, and 6 recorded in some genera — 9, 8, C nie: 1981a). A base number of x = 8 seems likely for Poissonia, a hypothesis consistent with the patterns of karyological variation in the tribe. Basic chromosome number for Desmodieae is ipee x = 11, but at least Pycnospora and the one species of Brya previously counted have n — 10 (Goldblatt, 19812). This first count for B. buxi- folia is consistent with the earlier record for the genus. 1188 Annals of the Missouri Botanical Garden Basic number for Phaseoleae is x — 11, number also probably basic for all eight subtribes (Goldblatt, 1981a). The counts here for Neoru- dolphia (Erythrininae), a monotypic genus previ- ously uncounted, and Neorautanenia brachypus (Phaseolinae) are consistent with this pattern. The count for Neorudolphia is of interest in view of its possible relationship with the large genus Ery- thrina, whic er in Neorudolphia confirms data from other as x — 21. The chromosome num- sources that it is probably not closely allied to Erythrina My count of 2n — 20 in Pachecoa prismatica (Aeschynomeneae-Stylosanthinae), cited by Nor- man & Gunn (1985), accords with the base number of x — the nnus four genera of the subtribe. Arthro- m is uncounted while Chapmannia has x — 1 “Goldblatt. 1981a, b). The last-mentioned two genera are most closely allied to Pachecoa (Nor- man & Gunn, 1985). 10 in Arachis and Stylosanthes, two of I extend my thanks to all those who provided the living material used in this study.

JUJUYANUM (BRASSICACEAE), NEW SPECIES FROM JUJUY, ARGENTINA Several new taxa and nomenclatural changes have been published (Al-Shehbaz, 1986; Boelcke, 1964, 1984, 1986) following the treatments of Thellung (1906) and Hitchcock (1945) on the South American species of Lepidium. The genus, which is represented in South America by probably more than 50 species, is in need of a comprehensive study. Species boundaries within certain complexes are artificial, and the variation of many taxa is poorly understoo he two novelties described below were initially sent to Professor Reed C. Rollins for identification. I am grateful to him for making them available for my study. Each of these is known only from the holotype. Lepidium boelckei Al-Shehbaz, sp. nov. TYPE: Argentina.

Perennial herbs, with a woody, unbranched cau- dex 1-2 cm diam. Stems few to several from the caudex, ascending to subdecumbent, villous, 6-15 cm long. Basal leaves spatulate, petiolate, obtuse to rounded at apex, attenuate at base, earlier ones entire, later ones dentate to subincised, 1.6-4 cm long, 3-8 mm wide, the blades glabrous or hirsute along the midrib; petioles flattened, densely hirsute, 1-2.5 cm long. Cauline leaves few, spatulate to oblanceolate, entire, attenuate and subsessile at base, 5-11 mm long, 1-3 mm wide. Inflorescences densely flowered, ebracteate, corymbose racemes, considerably elongated in fruit; fruiting pedicels ascending, densely puberulous to subhirsute, 5-7 mm long.

Seeds oblong, blackish, wingless, flattened, ca. 3 x 1.5 mm. Lepidium boelckei, which is named after Dr. Osvaldo Boelcke, authority on the Argentinian Brassicaceae and author of several species of Le- pidium, is easily distinguished from all of the pe- rennial South American species in having narrowly elliptic fruits 6-7 mm long, persistent sepals with a broad white margin, conspicuous styles well- exserted beyond the apical fruit notch, and sub- decumbent stems from a thick woody caudex. The Brazilian L. grandifructum C. L. Hitchc. is the only other South American species with fruits as large as those of L. boelckei. However, the former is a robust, erect plant with caducous sepals, six stamens, and included styles. Evidently, the two species are unrelated, and L. boelckei has no close relatives.
