Tropical American Plants, V
The notes which make up this paper result from the study of materials sent for determination and, especially, from the study of the Melastomaceae in revising that family for the Flora of Guate- mala.
I wish to express my thanks to those in charge of the several herbaria where I have gone to study the collections or who have lent critical specimens: United States National Herbarium, New York Botanical Garden, Gray Herbarium, Arnold Arboretum, Missouri Botanical Garden, Lundell Herbarium, University of Florida, Uni- versity of California, Escuela Agricola Panamericana and University of Michigan. Several persons have been most generous with their time or specimens: John J. Wurdack, H. W. Rickett and Marcela Cruz de Crary.
These studies and travel to other herbaria have been made pos- sible by a grant from the National Science Foundation.
The previous paper in this series appeared in Brittonia, 14 : 441- 446. 1962.
PINACEAE
The Museum library has just received a copy of a pamphlet by J. Ignacio Aguilar G., entitled Pinos de Guatemala. A note on the back cover states that the publication was first circulated in May 1953 and that the second edition (presumably the one in hand) was issued in November 1958; but the note is dated May 1961.
In the pamphlet a new form of pine is described; an old name for a Guatemalan pine is put into a new combination as a form; a new species is described but is said to date back to 1942, possibly in a Catalogo del Museo National de Ciencias Naturales de La Aurora (in our copy of which the name does not appear) . None of these names are properly published and have no validity.
ANONACEAE
Unonopsis R. E. Fries is a small genus of some 25 species. Three species have been recorded from Central America and Panama:

546 FIELDIANA: BOTANY, VOLUME 29
U. Pittieri Safford from the Canal Zone; U. Schippii Fries from British Honduras but reduced by Standley in Flora of Guatemala to U. Pittieri, perhaps incorrectly so; and U. costaricensis Fries from the Meseta Central of Costa Rica. In addition to those, U. Storkii is described below. It is a lowland species, but one in which the monocarpia are somewhat elongated and have two to several seeds. Another species, which is apparently undescribed, occurs in the Pal- mar region of Costa Rica. It is a small tree (4 m.) with narrowly elliptic leaves, the secondary nerves widely separated (1 cm. or usually nearly 2 cm.) and relatively few; the pedicels are subfiliform, not thick as in all other species.
Unonopsis Storkii Standl. & L. Wms., sp. nov.
Arbor parva usque ad 5 m. Folia late oblanceolata, breviter acuminata, base obtusa vel rotundata, nervi laterales utrinque 15-20; inflorescentia uniflora vel fascicula biflora; sepala 3, triangularia, pubescens; petala 6, impar, exteriora pubescens, valvata, cochleata, subtriangularia, crassa, interiora parva, cochleata, transverse rhombica, crassa, extus medium sericea; monocarpia 6 vel plura, ovoidea, sericea; semina discoidea.
Small tree to 5 m., branchlets slender, terete, densely but inconspicuously puberulent, becoming glabrous, internodes 2.5-4.5 cm. apart; leaves broadly oblanceolate, short-acuminate, obtuse or rounded at the narrow base, glabrous except the nerves below inconspicuously pubescent, secondary nerves about 15-20 on each side, blade 25-35 cm. long and 6.5-12 cm. broad well above the middle; petiole thick and fleshy, 0.5-0.8 cm. long and 0.3-0.5 mm. thick; inflorescence 1 flower, or 2-flowered fascicles from old wood, the peduncle stout, with a bract at the middle or below, ferruginous-pubescent, 1-2 cm. long; sepals 3, triangular, ferruginous-pubescent, about 2-3 mm. long; petals 6, in 2 series; petals of outer series valvate, strongly cochleate and subtriangular in outline, fleshy especially at the apex, densely ferruginous or sericeous-pubescent outside, 7-8 mm. long and nearly as broad; petals of inner series smaller, cochleate, transversely rhombic, very fleshy, glabrous except along the median line dorsally, about 4.5 mm. long and slightly broader; torus when mature spherical, bearing several (6 or more) stipitate monocarpia; monocarpia ovoid, puberulent, becoming glabrous, to 2 cm. long and 1.5 cm. in diameter, stipe about 0.5 cm. long, stout; seeds 2-6 in each monocarpium, flattened and sublenticular, with a prominent median ridge around the center, surface prominently pitted, about 1 cm. long and about as broad, 2-3 mm. thick along the border.
COSTA RICA: "Flower parts leathery, dull yellow, fruits now olive- green, in fact looking like olives; the seeds seem to be wafer-like, packed tandem, about 6 to each fruit; 5 meter tree in understory beneath Cativo, Carapa, etc."; 6 miles upstream from mouth of Estrella River, Prov. Limon, Apr. 19, 1952, Harvey E. Stork 4608 (UC, type; F).

PANAMA: Small tree, Changuinola Valley, Prov. Bocas del Toro, Feb. 22, 1924, V. C. Dunlap (F).
The several seeds in each monocarpium seem to distinguish this species from others in the area; the ovoid, puberulent monocarpia are distinctive also. The description of the flowers was made from buds at point of anthesis.
STAPHYLEACEAE
Turpinia heterophylla (Ruiz & Pavon) Harms & Loess., Engler, Bot. Jahrb. 37: 575. 1906. Staphylea heterophylla Ruiz & Pavon, Fl. Peruv. et Chil. 3: 29, t. 253. 1802.
COSTA RICA: Flowers white, edge of sphagnum bog, next to Pan American highway between km. 18 and 20 from El Empalme to Villa Mills, Prov. San Jose*, alt. 2700 m., Aug. 15, 1960, Marcela Cruz 165.
Two other species of Turpinia are known in Costa Rica. This Andean species, reported for the first time for North America, was among a fine collection of plants made by Miss Cruz in the Cordillera de Talamanca.
RHAMNACEAE Rhamnus oreodendron L. Wms., sp. nov.
Arbor parva; folia oblongo-lanceolata vel lanceolata, acuminata; inflorescentia fascicula 1-4-flora in axilla foliorum; calyx 5-lobata, lobis triangularis, crassis; petala obovata, retusa, cochleata; fructa baccata.
Small trees with slender, terete, sparsely sericeous-pubescent branchlets which become glabrous with age; leaves alternate, blade oblong-lanceolate or lanceolate, crenulate, acuminate, base obtuse or rounded, glabrous except the veins sparsely sericeous-pubescent below, only the mid-vein pubescent above, darker green above than below, 3-7 cm. long and 1.5-3.5 cm. broad, petiole slender, sericeous, about 1-1.5 cm. long, the stipules sericeous, linear, about 2.5 mm. long; inflorescence a 1-4-flowered axillary fascicle, pedicels 9-14 mm. long, sparsely sericeous-pubes- cent; calyx 5-lobed, apparently valvate in bud, hypanthium and calyx about 4 mm. long in flower, glabrescent, the calyx lobes triangular, acute, somewhat fleshy, about 2.5 mm. long and as broad at the base; petals obovate, retuse, cune- ate to the base, cochleate, inconspicuous, about 1.5 mm. long, borne from a torus- like process between the calyx lobes; stamens borne from the base of the petals and partially enclosed by them; style about 1 mm. long; fruit baccate, spherical, glabrous, about 6-7 mm. in diameter (nearly mature).

There are no close relatives in North America ; however, Rhamnus Goudotiana Tr. & PI., which is not uncommon in the Andes of Co- lombia, is similar. Our species is distinguished in having the calyx lobes persistent at least to nearly mature fruit, not circumscissile soon after an thesis as is the case with nearly all other species; peti- oles are longer and leaf blades are differently shaped and broader in relation to length.
The type material is in nearly mature fruit with a few old flowers present.
FLACOURTIACEAE
Casearia coronata Standl. & L. Wms., sp. nov.
Arbor vel frutex usque ad 2 m. altus. Folia elliptica vel elliptico-oblanceo- lata, acuminata, breviter petiolata; inflorescentia fasciculata; sepala biseriata, late ovata, obovata vel orbicularia; stamina ±8; filamenta et staminodia in corona connata, staminodia barbata.
Small trees or shrubs, about 2 m. tall, branches slender, grayish, puberulent, soon glabrate, leaves short-petiolate, elliptic to elliptic-oblanceolate, acuminate, glabrous, with about six main lateral nerves on each side, the blade 10-20 cm. long and 3-7 cm. broad; petiole short, puberulent or glabrate, about 1 cm. long; inflorescences fasciculate, several-many-flowered, borne in the axils of leaves or on the branches between leaf internodes; peduncles puberulent, 3-4 mm. long, dehiscent near the apex; flowers medium-sized (for the genus), pedicel 1.5-2 mm. long, puberulent; calyx lobes 5-6, in two series and somewhat dissimilar, some (inner ones) broadly obovate-orbicular and unguiculate, some (outer ones) broadly ovate or ovate-orbicular, puberulent, mostly 3-4 mm. long and 3-3.5 mm. broad; petals none; stamens about 8, 2.5-3 mm. long, alternating and connate with staminodes of about equal length into a corona; the staminodes flattened, conspicuously pilose-barbate on the apices; stigma entire, short, about 1 mm. long; fruits (fide Stork) "turning red, somewhat triangular"; ovary at anthesis 1.5-2 mm. long, puberulent.
COSTA RICA: Perianth pale green, small tree of 2 meters, only 2 fruits seen, turning red, somewhat triangular, 6 miles inland from mouth of Estrella River, Prov. Limon, Apr. 21, 1952, Harvey E. Stork 4616 (type, F; UC).
Most closely related to C. javitensis var. myriantha (Turcz.) L. Wms. of the species recorded from Central America and Panama. The leaves are not coriaceous and not at all glossy; the perianth segments are much broader and somewhat larger; the relatively large corona, made up of the staminodes and adnate filaments, is distinc- tive as is the prominent "beard" at the apex of each staminode. Unfortunately, mature fruits are not present.

MELASTOMACEAE
There are some 200 genera and perhaps 4,000-5,000 species of the Melastomaceae. Approximately two-thirds of these are in the neo- tropics, the rest in the tropics of the old world.
The family is a fascinating one and often the individual species are most attractive. Many of the species, however, are small-flow- ered, especially among the Miconieae. In that subfamily the genera (and often the species) are very difficult to separate. There are really no satisfactory boundaries between many of the genera. Sec- tions of Miconia often seem more distinct than some of the genera that are maintained. There is obviously need for a study of generic boundaries of many genera but especially of Miconia and the sev- eral genera closely allied to it. This work can best be done by a student who can devote much time to the study of this complex assemblage.
In the preparation of the manuscript for the Flora of Guatemala the material available from Mexico, Central America, the Caribbean region and South America has been studied with the hope that the account prepared would be as accurate as possible. More critical study will certainly indicate other desirable changes. The study of the vast genus Miconia has been especially difficult and a better understanding of it is desirable.
Aciotis Levyana Cogn. in Mart. Fl. Bras. 14, pt. 3: 460. 1885.
The species was described originally from Nicaragua (Levy 1+97, phototype F). I have seen specimens from Guatemala, British Hon- duras, Honduras, Nicaragua, Costa Rica, Panama and Colombia. There are four sheets in the Lundell Herbarium from British Hon- duras (Gentle 8249, 8403, 8610, 9248), the first seen from the colony although the species had been reported.

In Guatemala there are three species of Arthrostemma which I am able to distinguish one from the other. No others occur in Cen- tral America or Panama.
Arthrostemma alatum Triana, Trans. Linn. Soc. Bot. 28: 35. 1871.

Originally described from Venezuela and now known also from Mexico, Guatemala, El Salvador, Costa Rica and Panama. The alate stems and relatively short sessile hypanthium distinguish the species superficially.
Arthrostemma parvifolium Cogn. in DC. Monog. Phan. 7: 143. 1891. A. apodocarpum Donn.-Sm. Bot. Gaz. 37: 210. 1904.
Originally described from Guatemala, now known also from Mexico and British Honduras. The sessile fertile flowers distin- guish this from the following species, the long hypanthium from A. alatum.

Traditionally two species have been set apart in Mexico and Central America for the material which I would associate with an older name (A. ciliatum} based on South American material. These two species, A. fragile Lindl. and A. macrodesmum Gleason [A. cam- panulare (Naud.) Triana], have been separated on the comparative length of the connective and anther cells of the stamens borne opposite the sepal lobes. If the connective was much shorter than the anther cell the plant was called A. fragile; if the two were about equal in length or the connective was longer the plant was called A. macrodesmum. Abundant material of this complex is available but more often than not the petals and stamens, which are fugaceous, are not available on the specimens. When these characters are vis- ible they usually hold for any given specimen. There are, however, specimens that might as well go into one as the other of these two species. Furthermore, while the anthers in this complex are usually dimorphic — those opposite the sepals in one series, those opposite the petals in another — this is not always the case and all anthers may be similar. The appendages of the anthers show considerable vari- ation, which is possibly of no or but little taxonomic significance, and I find no mention of it.
My knowledge of A. ciliatum R. & P. is based on the original plate and a Ruiz and Pavon specimen in our herbarium received from "antique herbario generali, Herbario Horti Botanici Matriten- sis," numbered 11/93, and collected in Cuchero.

Bellucia Rafinesque is a small genus of eight or ten not very dis- tinct species, mostly of northern South America. Several have been reported in tropical North America, mostly perhaps in error, but until the material is brought together and revised no very secure idea may be had of them. Two species are currently distinguished from our area, B. grossularioides and B. costaricensis. They seem to me dubiously distinct but will be maintained in the Flora of Guate- mala.
Bellucia grossularioides (L.) Triana, Trans. Linn. Soc. Bot. 28: 141. 1871. Melastoma grossularioides L. Sp. PI. 390. 1753.
The oldest species in the genus and one of the most widely dis- tributed. In North America we have material from Guatemala, British Honduras, and Panama, and it is doubtless this species that is reported from Mexico by Hemsley (Biol. Centr.-Am. Bot. 1: 432. 1880) as B. macrophylla (D. Don) Naud. In South America it is in the Guianas, Venezuela, Colombia, and Ecuador.
This species may be distinguished from B. costaricensis by in- florescences usually 1-flowered and borne in the axils of existing leaves, not several or even short cymes borne usually on old wood; the calyx ruptures into unequal lobes and usually soon falls away, while in B. costaricensis the lobes are usually 5 and quite regular and apparently persistent. The nerves of the leaves of this species might be described as 5-plinerved while those of B. costaricensis might better be described as 5-nerved, the lowest lateral originating at or near the base while the higher lateral pair originate usually 1 cm. or more higher along the mid-nerve. This last character, however, is probably of no value and more apparent than real.
Bellucia costaricensis Cogn. Bull. Soc. Bot. Belg. 30 (1) : 264. 1891; Cogn. in Durand & Pittier, Prim. Fl. Cost. 1: 167. 1891.
The species was based on material from Costa Rica and was doubtless seen by Cogniaux too late to put it into his monograph of the family, even though it was published in the same year. He gave no reason for distinguishing it from other species of the genus, and I find very little except that mentioned under the preceding species.
We have material (often incomplete) from Mexico, Guatemala, British Honduras, Nicaragua, Costa Rica and Panama. The spe- cies occurs also in Colombia (Cuatrecasas 17119).
552 FIELDIANA: BOTANY, VOLUME 29
Centradenia G. Don is a small genus of Mexico, Central America and Panama, with one of its species extending into Colombia. Cog- niaux (in DC. Monog. Phan. 7: 116-119. 1891) has divided the genus into two sections, depending on whether the stamens are essentially isomorphic (Sect. Centradeniopsis) or quite unequal (Sect. Eucentra- denia). Whether or not this character is always of sufficient value in setting up subgeneric entities seems to me to be doubtful. There are two species accepted by both Cogniaux and Gleason so similar that without looking at the anthers they would be placed in the same species. These two species are Centradenia floribunda Planch., stamens similar, and C. Bernoullii Cario ex Cogn. (=C. floribunda var. Bernoullii, see below) with stamens in two unequal sets. It would be of interest to study a colony of these plants in the field to see if intermediates, which seem to be indicated by herbarium material, are not to be found. The herbarium material available is not sufficient to make a study, but there are several Guatemalan specimens which were placed in C. Bernoullii by Standley and these seem to me closer to C. floribunda, although they may well be some- what intermediate. A parallel condition exists between Pterolepis pumila (Bonpl.) Cogn. and P. trichotoma (Rottb.) Cogn.
Centradenia floribunda Planch, var. floribunda. C. flori- bunda Planch. Fl. Serres 5: t. 453. 1849. C. floribunda var. grandi- folia Cogn. in Donn.-Sm. Bot. Gaz. 20: 286. 1895.
This is the oldest name in this complex. The stamens are all much alike and none of the appendages on the filaments has a pair of long setose processes, as is the case in the following variety.
Centradenia floribunda var. Bernoullii (Cario) L. Wms., comb. nov. Centradenia Bernoullii Cario ex Cogn. in DC. Monog. Phan. 7: 118. 1891.
The variety is distinguished primarily by the dimorphic anthers, one set of which has two long setose processes on the appendage of each anther. The geographical range of this variety is El Salvador and Honduras. It has been reported from Guatemala but appar- ently based on misidentifications. Some of the Honduran specimens approach the typical variety (Williams & Molina 18082; Standley & Chacon 6493).
When stamens are lacking on herbarium specimens I have found no way to distinguish this variety from the typical one.

A distinctive species from Mexico and Guatemala, easily sepa- rated from the others by the hypanthium and short, broad calyx lobes. All of the Costa Rican material determined by Gleason and Standley with this name belongs to the quite different C. salicifolia Brandegee.
I have seen the following Guatemalan material, all from the De- partment of Alta Verapaz: Goll 168 (US); Donnell Smith 15^0 (US); Stuart 15 (Mich.); von Tuerckheim 883 (US); Wilson 18J,. (F).

This is the type species of the genus Centradenia. It is widely distributed in Mexico, whence the type. It is known from several localities in northern Central America but is rare. In Costa Rica the species is common, and it is known from a few localities in Panama.
A photograph (CNHM no. 16683, taken in Berlin) of what is presumed to have been the type of C. divaricata collected by War- scewicz, possibly in Costa Rica or Panama, along with a diagnostic sketch showing an anther, indicates that it belongs here as a synonym.
An isotype of C. inaequilateralis var. major collected in Mexico by Galeotti (2963 A) shows that it is a somewhat large-leafed form of the species as Cogniaux indicated, and not C. floribunda Planch, as annotated by Gleason.
Centradenia Maxoniana Gleason, Bull. Torr. Bot. Club 65: 571. 1938.
A name currently recorded from Costa Rica and Panama. It seems more than likely that it is a large-leafed form of C. floribunda Planch, hardly if at all different from the plants from Guatemala which Cogniaux called C. floribunda var. grandifolia. I have seen the type.

The species occurs in Mexico from Vera Cruz and Puebla to Chiapas. It is common in Guatemala in the highlands in the west, near Mexico. It then jumps to the highlands of Costa Rica, where it is again quite abundant. There is not a single known station in the highlands between western Guatemala and Costa Rica. The species is to be expected in Honduras and Nicaragua.
The Costa Rican material differs from that of Mexico and Guate- mala by having the pubescence in the inflorescence consistently more dense. I have found no other distinctive character than this very minor one. Dr. Gleason and Dr. Standley had determined all the Costa Rican material (as well as some of that from Guatemala) which they saw as Centradenia grandifolia (Schlecht.) Endl. I have seen the following specimens from Mexico and Central America.
MEXICO: Matuda 2747 (Mich, US, GH, F), 3000 (Mich), 3001 (Mich, F), 3002 (Mich); Purpus 6103 (US, F), 6978 (US); Roby s.n. (US).
GUATEMALA: Standley 65325 (F, GH), 67764 (F), 83297 (F), 83716 (F), 83749 (F), 84577 (F), 85451 (F); Steyermark 33877, 34344, 35118, 35312, 36343, 36644, 37522, 37668 (all F).
COSTA RICA: Skutch 4205 (US); Smith H385, H418, PC251, PC315 (all F); Standley & Valeria 43312 (US, F), 44093 (US).
Clidemia D. Don in Guatemala and adjacent Central America and Mexico is difficult primarily because of two or three small groups of closely related species. Alfred Cogniaux (in DC. Monog. Phan. 7: 984-1026. 1891) prepared a good account of the genus as then known. Later H. A. Gleason (in Brittonia 3: 97-140. 1939) pre- pared a revision of those in tropical North America. The account of the genus which will appear in the Flora of Guatemala owes much to both of these treatments. A few changes have been made and the Central American plants formerly referred to Heterotrichium are transferred to Clidemia. Comment concerning the genus Hetero- trichium will be found under that name.
The situation in these genera is not so simple as that, however. Tococa Aubl., Maieta Aubl., and Clidemia D. Don are very closely allied and they are genera of convenience at best. When Dr. Glea- son studied the myrmecophilous species of Clidemia (Bull. Torr. Bot. Club 58: 73-85. 1931) he took many of the species which had been described or transferred to Maieta and placed them in Clidemia, leaving in Maieta only Aublet's original species and a very closely allied one.
WILLIAMS: TROPICAL AMERICAN PLANTS, V 555
Tococa and Maieta have terminal inflorescences and are so dis- tinguished from Clidemia, which has lateral inflorescences. I find, however, that pseudoterminal or terminal inflorescences are of not uncommon occurrence in Clidemia and that a single species may have both types. Cogniaux and Gleason were both astute students of the Melastomaceae yet when Gleason described Clidemia spectabilis he assumed that it had lateral inflorescences. Cogniaux described the same species, placing it (I think erroneously) in Heterotrichium, a genus which he understood as having terminal inflorescences. More recently Dr. Suessenguth, no specialist in the family, apparently has described the same species as Maieta setosissima. The inflorescences are apparently both lateral and pseudoterminal.
The problem of generic limitation in this section of the Miconieae is involved and will require detailed study by the specialists in the family.
Clidemia capitellata. The varieties of C. capitellata in Central America are three, closely related and often difficult to distinguish. A key and an account of them follows:
Inflorescence branched (a dichasium), often rather simple; pubescence of under
side of leaf principally of stellate hairs var. neglecta.
Inflorescence unbranched or with a pair of branches at the base (rarely more);
pubescence of under side of leaf principally of crisped hairs. Inflorescence internodes about 1 cm. long or less, densely long hirsute and in- conspicuously glandular var. dependens.
Inflorescence internodes 1-2 cm. long, sparsely hirsute and conspicuously gland- ular var. capitellata.
Clidemia capitellata var. capitellata. Melastoma capitellata Bonpl. in Humb. & Bonpl. Monog. Melast. 5, t. 3. 1816. Clidemia capitellata D. Don, Mem. Wern. Soc. 4: 310. 1823.
Widely distributed, from Mexico through Central America and Panama to Colombia. Closely related to var. dependens, which may not always be distinguishable. See that variety for further comment.

556 FIELDIANA: BOTANY, VOLUME 29
pendens, in his review of the Mexican and Central American Clide- mias, are not at all stable and are maintained here with reservations. The inflorescences are usually unbranched but in a few specimens seen are branched at the base and even through their length, in this respect approaching var. neglecta. The characters of pubescence in the inflorescence, type and length of the hirsute hairs and glandu- losity, are tenuous at best.
Clidemia capitellata var. neglecta (D. Don) L. Wms., comb, nov. Clidemia neglecta D; Don, Mem. Wern. Soc. 4: 307. 1826.
A widely distributed variation of C. capitellata and perhaps more closely related to var. dependens than to var. capitellata. The range falls within that of the other two varieties. In var. neglecta the in- florescence is usually a dichasium, often quite diffuse, while in the other varieties branching occurs but rarely; the pubescence of the under side of the leaves is short, soft and stellate, while in the other varieties it is rather coarse and crisped, although occasionally soft stellate pubescence does occur.
The Mexican Clidemia chinantlana Triana appears, from a type photograph, to belong here. Dr. Gleason separated them widely in his revision but the type would not key out in his key.

The species belongs among the myrmecophilous species of Cli- demia and inconspicuous formicaria are to be found on a few leaves. The leaves of the species must be attractive to insects, for those on all specimens seen have been chewed.
The inflorescences of this species may be either lateral or pseudo- terminal or both.

This species is related to C. octona but may be distinguished by the generally smaller flowers, lack of a corona on the torus, much greater number of stamens, and very different shape of the anthers with much less conspicuous connective not at all prolonged.

Widely distributed from Mexico through Central America, Pan- ama and the West Indies, southward to Brazil and Peru. The species is closely related to Clidemia hirta (L.) D. Don. The inflorescence of the species is either lateral or apparently terminal, although if terminal there are often two or three inflorescences borne at each place — one in the axil of a leaf, one terminal, and another in the axil of the opposite leaf. Often also there are one or two inflorescences which appear lateral when one of the lateral buds has continued as a branch and not as an inflorescence.
This species has been treated as a species of Heterotrichium by most botanists since that genus was founded. However, as pointed out below under Heterotrichium, the type of that genus is quite different.
WILLIAMS: TROPICAL AMERICAN PLANTS, V 559
It is interesting to note that specimens of this species having lateral inflorescences have often been placed in Clidemia hirta, while specimens of Clidemia hirta apparently with terminal inflorescences have been determined as Heterotrichium octonum. Cogniaux' H. oc- tonum var. brasiliensis has lateral inflorescences (on our Pohl 1517} and would seem to be Clidemia hirta.
A photograph of the type of Miconia phaeotricha Naudin (Ann. Sci. Nat. ser. 3, 16: 193. 1851) indicates that it may belong here as a synonym.

Dr. Gleason in his review of The Genus Clidemia in Mexico and Central America used the name Clidemia Deppeana for this plant, saying that Standley was the first to revive it. Standley did take up the name (Contr. U. S. Nat. Herb. 23: 1072. 1924) and gave as synonym "Melastoma petiolare Schlecht. & Cham. 1830, not M. petiolare Mill. 1768." Miller, however, spelled his specific epithet as Melastoma petiolatis (in Index Kewensis it is given as M. petiolatum).
There occurs, however, Melastoma petiolare Wall. (A numerical list of dried plants, etc. no. 4053) in his so-called catalogue. The date given on the title page of Wallich's work is 1828, but the sheet on which no. 4053 appeared apparently was published in 1831 (see 0. Kuntze, Rev. Gen. PI. 1: CXLV. 1891, and translation in Kew Bull. 1913: 260. 1913).
In making the new name Clidemia Deppeana, Steudel merely cited "Melastoma petiolaris. Chms. Schl." as a basionym and there is no way of telling which name he thought was a homonym of Schlechtendal & Chamisso's name.
It seems that Melastoma petiolare Schlecht. & Cham, and Mela- stoma petiolatis (or petiolatum) Miller are different names, and the use of one does not preclude the use of the other. Further it appears that Melastoma petiolare Schlecht. & Cham, was actually published a year before Meiastoma petiolare Wall, and therefore is not a homo-
560 FIELDIANA: BOTANY, VOLUME 29
nym of it; besides, Wallich's name was a nomen nudum and hence not validly published.
Clidemia serrulata was maintained by Dr. Gleason, in the revi- sion mentioned above, with the comment that "Neither is the dis- tinction between this species and the commoner C. Deppeana very sharp." The comment seems to me to be justified, for there are in our collection specimens annotated by Gleason with these two names, but the specimens are so similar that they might well have been taken from the same bush.

The only specimens which I have seen are isotypes of the orig- inal collection. This species is, I believe, most closely related to the myrmecophilous species of Clidemia although there is no indication of formicaria on specimens I have seen, nor did Brandegee mention them on his specimens. It is curious, however, that he did call attention to the similarity of the setose processes of the stem to those of Maieta setosa Cogn., now usually treated as one of the myrmecophilous species of Clidemia. The most closely related spe- cies seems to be C. globuliflora (Cogn.) L. Wms., mentioned above.

I am unable to see any difference in these two concepts, and in fact it appears that C. reticulata is distinguished on a character which depends upon maturity of the specimen. The inflorescence on immature specimens is not so open as that on mature specimens.
The type is from Jamaica. The species is common in British Honduras; there is a single specimen from Nicaragua (Standley 19998); it is reported from Costa Rica and Panama; West Indies; British Guiana and Venezuela to Peru.

Conostegia D. Don is a rather distinctive genus among the Cen- tral American Miconieae due primarily to the calyptriform calyx which dehisces and falls away at anthesis. A review of the genus by Cogniaux was published in 1891. Dr. Wurdack is gathering materials for a much-needed revision. About 45 species have been described from Mexico, Central America and Panama. Conostegia xalapensis (Bonpl.) D. Don is the commonest and most widely dis- tributed melastome through most ecological situations in the area below 1,800 m. and is often a weed in pastures.

One of the most distinctive species of Conostegia in Central Amer- ica. It is allied to C. Brenesii Standl. and C. speciosa Naudin, both of southern Central America. The superficial resemblance and type of stellate hairs reminds one of Miconia barbinervis (Benth.) Triana.

There is considerable question as to the proper specific epithet for the accumulation of material placed here. In Central America and Mexico there are other species which may very well belong here — C. chiriquensis Gleason, C. Oerstediana Berg, and C. volca- nalis Standl. & Steyerm., among them.

A small tree 8 m. tall and the trunk about 10 cm. in diameter, the branches and petioles at first densely stellate or plumose-stellate pubescent, both becoming glabrous with age. Leaves elliptic-lanceolate, acuminate, acute or cuneate to the base, denticulate, 5-plinerved with the outer pair of nerves arising near the base of the blade and the inner pair 1 cm. or more above the base, the nerves of each pair arising at different places on the mid-nerve, the upper surface densely stellate pubescent but soon becoming glabrous or nearly so, dense and persistent stellate- pubescence completely covering the under surface; blade 6-18 cm. long and 2.5- 5.5 cm. broad, those of a pair apparently very unequal; petioles 1.5-2.5 cm. long; inflorescences terminal or pseudolateral, densely pubescent with stellate or plumose hairs, dichasioid with the lateral branches congested and subcapitate at first, the branches of the inflorescence elongating (to about 4 cm.) with age and spicate and somewhat fractiflex, with reflexed linear-lanceolate bracts opposite or perhaps subtending the flowers; flowers to about 8 mm. long, white, hypanthium 2-3 mm. high and 3-4 mm. broad, subglobose, densely plumose or stellate-pubescent; calyx calyptriform, falling away as a unit, conic, with 6 longitudinal subapical append- ages about equaling the calyptra, pubescence as on the hypanthium; petals 6, ovate or subrhombic-ovate, about 5 mm. long and 3 mm. broad; anthers about 2.5-3 mm. long.

The species is not closely related to any species known to me. In superficial aspect it somewhat resembles Conostegia xalapensis because of the densely stellate -pubescent undersurfaces of the leaves; but the appendages of the calyptra distinguish it from all species that I know, and the plumose or barbellate pubescence of the flowers and inflorescence, and the form of the inflorescence are distinctive.

The genus Calyptrella of Naudin was originally described from a Galeotti specimen (2959) from Mexico. It has been found, however, that the plants referred to this generic name are much more abun- dant in South America than they are in North America. Ten spe- cies have been credited to Calyptrella, three of these from North
WILLIAMS: TROPICAL AMERICAN PLANTS, V 563
America, where plants of this affinity are rare. The remaining seven were described from South America, but one of these, Calyptrella littoralis Gleason, seems not to belong in Graffenrieda.
In preparing the manuscript for the one species that is known to occur in Guatemala the entire genus Calyptrella was studied and it was soon realized that Calyptrella denticulata Gleason and C. stellata Gleason belonged in the closely allied genus Graffenrieda. Further study of the two genera revealed that the only difference between them was whether the calyx ruptured and separated from the hypan- thium as a calyptra (in Calyptrella) or whether the calyx was more or less normal in forming lobes — these sometimes formed by the rup- turing of the calyx (in Graffenrieda). Furthermore, the calyces in Calyptrella in age tend to break away or are deciduous.
The stamen structure, often used for generic separation in this family, seems to offer no characters. Seeds seem to be much alike in the two groups of species. The large genus Conostegia, not allied to Graffenrieda and Calyptrella, is usually characterized by having a calyptriform calyx, but sometimes the calyx ruptures into lobes and is more or less persistent.
There seems to be no justification for maintaining Graffenrieda and Calyptrella as distinct genera and I propose that most species of Calyptrella be transferred to Graffenrieda, the older name.

EXCLUDED SPECIES
Calyptrella littoralis Gleason, Bull. Torr. Bot. Club 72: 473. 1945. This species seems not to belong in Graffenrieda but our specimen is inadequate to verify its systematic position.
Henriettea DC. and Henriettella Naudin. In preparing the ac- count of the Melastomaceae for the Flora of Guatemala I came to the conclusion that the type species of these genera in fact belonged in the same genus. Some twenty years ago, Macbride, in the Flora of Peru, concluded that the two entities were not distinguishable and placed the Peruvian species of the two genera together. These two generic concepts have ascribed to them perhaps some fifty or sixty species, of which very few are found in Central America or Panama.
WILLIAMS: TROPICAL AMERICAN PLANTS, V 565
While the type species of the two are very similar there are species placed here that perhaps would go elsewhere as well or better. I am concerned only with those of Central America and Panama at the present time, and fortunately the type species of both genera are to be found in our region.
Dr. Gleason, astute student of the family, in his account of The Melastomaceae of the Yucatan Peninsula described Henriettea strigosa and placed it alongside H. succosa (Aubl.) DC., which is the type species of Henriettea. However, there seems to be no difference be- tween Gleason's Henriettea strigosa and Henriettella Seemannii Nau- din, the type species of the genus Henriettella. In placing these two species in the same genus Gleason has indicated effectively that the two genera have but little foundation in fact.
There are in Central America and Panama the following species which may be placed in Henriettea DC., the older of the two generic names.
Henriettea cuneata (Standl.) L. Wms., comb. nov. Maieta cuneata Standl. Field Mus. Bot. 8: 30. 1930. Henriettella cuneata Gleason, Bull. Torr. Bot. Club 58: 75. 1931.
Known only from Guatemala and British Honduras. Formicaria are to be found at the base of the leaf blades, partially obscured by long brownish pubescence. The material available is inadequate but I know nothing better to do with this species than to place it here.

Known from Guatemala, British Honduras, Honduras and Pan- ama. Dr. Gleason has placed this anomalous species in Clidemia, where it goes no better than in Henriettea. Better material is needed.
Henriettea fascicularis (Sw.) Gomez, Anal. Hist. Nat. Madrid 23: 68. 1894. Melastoma fascicularis Swartz, Prodr. 71. 1788. Ossaea fascicularis Griseb. Fl. Br. W. Ind. 246. 1860. Henriettella fascicu- laris Triana, Trans. Linn. Soc. Bot. 28: 143. 1871.
Although Gomez' combination is not well made there seems to be no question as to his intent, so the name is accepted. The spe- cies is a fairly common one, known from the Greater Antilles, Cen- tral America and Panama.

Known from British Honduras, Panama and Colombia (fide Gleason) .
There seems to be no differences in the concepts given above. This is the type species of the genus Henriettella Naudin. The petals are acute or retuse, or perhaps even obtuse, for Gleason described the petals of Henriettea strigosa as triangular-ovate, although they were acute or obscurely retuse to retuse in flowers from an isotype which I examined. Henriettea par vi flora (Triana) Griseb. of Cuba is very closely related to this species.

There are in Central America four species of Heterocentron, with perhaps a half dozen additional ones in Mexico. Cogniaux (in DC. Monog. Phan. 7 : 135-139. 1891) distributed the then known material into six species. Gleason (Bull. Torr. Bot. Club 65: 572-575. 1938) described four new species of the genus and at the same time briefly reviewed those known. Later (1950) he described one more species, bringing the number of species which he recognized to sixteen.
WILLIAMS: TROPICAL AMERICAN PLANTS, V 567
A review of Heterocentron for the Flora of Guatemala (all the spe- cies known in Central America occur in Guatemala) has suggested a more conservative account of them, based on reasonably abundant collections and long acquaintance with them in the field. The four species are the following:
Heterocentron elegans (Schlecht.) Kuntze, Rev. Gen. PI. 1: 247. 1891. Rhexia elegans Schlecht. Linnaea 13: 432. 1839. H. ses- silis Gleason, Bull. Torr. Bot.

Southern Mexico and Guatemala.
A rare species known from fewer than a dozen collections. There is no question that the fruiting type of Monochaetum guatemalense belongs here rather than in the genus Monochaetum.

Known only from a rather restricted area in Guatemala.
This species is closely related to H. elegans (Schlecht.) Kuntze and when more adequate study material is available they may prove to be the same; however, there seem to be several minor differences.
Heterocentron suffruticosum Brandegee, Univ. Cal. Publ. Bot. 6: 57. 1914.

Bot. Club 65: 575. 1938. H. hondurense Gleason, Phytologia 3: 360. 1950.
A widespread and variable species found from Mexico through Central America to Panama. Mountain thickets and on moist banks or most commonly in oak-pine woodlands, 1,300-2,500 meters.
The petals of this species vary from deep purple to rose to white, becoming lighter with age; they are also quite variable in size. The sepals are somewhat variable in shape and size but in pubescence they vary from completely glabrous to ciliate and occasionally hir- sute on the outer surface; the lobes are mostly about the same length as the hypanthium. The hypanthium again does not vary greatly in size and shape but the hirsute pubescence may vary from quite dense to almost none (or occasionally glabrous) and from eglandular to prominently glandular; it is tuberculate (especially in age) to quite smooth. The capsule is 4-lobed and each lobe usually has a horny terminal appendage which may be entire or emarginate, gla- brous or ciliate or even glandular-ciliate. The leaves are not more variable than might be expected in a species of which a large num- ber of specimens are available for study; however, the pubescence does vary greatly in quantity; it is found on both sides of the leaves and is occasionally sparse although usually not, and on a few speci- mens is quite dense. The stems are herbaceous or suffruticose, prom- inently 4-angled, especially in living material, usually red or reddish as are the new leaves, and variously strigose. Comparative lengths of portions of the anthers have been used to segregate species but here again I find nothing constant.
Heterotrichium DC. Prodr. 3: 173. 1828, the selection of a generic type.
Heterotrichium is a genus of the Miconieae described by De Can- dolle and to which he assigned five species. These five species are not all congeneric, at least not within the limits usually accepted for genera in the Miconieae. The selection of a type species for this genus presents a few problems but these are not serious. First, the number of species may be reduced to four by placing H. niveum (Desr.) DC. (of which he had no specimen in his own herbarium) into the synonymy of H. patens (Sw.) DC. De Candolle says of the species of the germs that they are "Frutices Domingenses." It seems logical therefore to think that when De Candolle first wrote the description and set the genus apart in manuscript he had specimens only from the island of Santo Domingo. This would exclude H. oc-
WILLIAMS: TROPICAL AMERICAN PLANTS, V 569
tonum (Bonpl.) DC. and H. novemnervium DC. from consideration in the selection of a generic type, for he gave the range of the first as "Amer. aust. monte Quindiu . . ." and of the second as "in Bra- silia." Furthermore, both these species would be better placed in Clidemia, and one has been transferred there long since. In addi- tion, De Candolle commented that "Torus in H. octono a calyce facile separabilis tunicam apice dentatam circa ovarium conficit"- a further reason to exclude that species from consideration and one which points to its relationship with Clidemia hirta (L.) D. Don.
The two species remaining, H. angustifolium DC. and H. patens (Sw.) DC., have most of the generic characters given by De Candolle although they belong to different genera. However, the leaves of the genus are described as "Folia petiolata superne setosa subtus in nervis hispida, inter nervos velutina." Heterotrichium angustifolium has the leaves setose above while H. patens does not. The generic description of the anthers is essentially the same as the description of the anthers given for H. angustifolium, while the anthers are not mentioned in the description of H. patens nor in that of H. niveum.
Heterotrichium angustifolium DC., for these reasons, is selected as type species of the genus Heterotrichium DC. The type specimen is one collected in Santo Domingo by Bertero and is in the De Can- dolle collection (photo F, NY). None of the other species placed in the genus by De Candolle seem to be congeneric with H. angusti- folium.
Leandra Raddi is a most unsatisfactory, and unfortunately large, assemblage of species which it is almost impossible to distinguish from Miconia in any adequate manner. Leandra is also related to Clidemia. The character often given to distinguish Leandra from Miconia, and other closely allied genera, is the acute petals — cer- tainly a tenuous character in a closely related group of genera that perhaps contains a thousand species or more. Leandra is a genus of convenience rather than one based on good morphological dis- tinctions.

The species is widely distributed, occurring from Guatemala through Central America and Panama, southward to Ecuador. The species illustrates well the difficulty of generic placement in
570 FIELDIANA: BOTANY, VOLUME 29
this group of plants. Specimens of this species determined as Mi- conia guatemalensis Cogn. by Donnell Smith, by Standley, and by Gleason have been passed over without comment by many botanists. The resemblance of the two species is striking.
Leandra costaricensis Cogn. will doubtless be found to be a syn- onym, for I find the presumed difference to be unimpressive. The species has been reported under this name from British Honduras.
Meriania Swartz, one of the most attractive genera of the Melas- tomaceae, has one species described as from Guatemala, M. macro- phylla Benth. The specimen was collected by Hartweg and it is curious that no one else has found the genus in Guatemala, where Hartweg is said to have found it. Hartweg collected extensively in Ecuador and it is possible that the unnumbered type is actually from that country. The species is known from Panama and Conoste- gia excelsa Pittier is a synonym.
The second species recorded from continental North America is M. panamensis Gleason from Chiriqui Volcano in Panama.
Miconia Ruiz & Pavon is the largest genus of the Melastomaceae, with perhaps seven or eight hundred species; of these, sixty-one are to be found in Guatemala and British Honduras. It may be found convenient eventually to conserve the name Miconia for there are valid generic names that are older and that may be shown to be con- generic with Miconia.

I find no differences between the Andean M. desmantha and the tropical North American species cited in synonymy above. The species, distributed from Mexico through Central America and Pan- ama to Colombia, is variable. Furthermore, there is an additional complication of the relationship of this species with M. aeruginosa Naudin, which has a similar geographical range. The two may be distinguished in most cases by the following key:
The young branches sparsely covered with short hirsute hairs; the upper surface of the leaves sparsely hirsute and stellate puberulent to almost glabrous.
M. desmantha.
The young branches with a dense covering of long hirsute hairs; the upper surface of the leaf quite densely long hirsute M. aeruginosa.

When Standley and Steyermark described these two species they said they were of "somewhat uncertain position." They should per- haps be placed in the genus Tetrazygia L. C. Rich., if that genus can be kept apart from Miconia. The species will be retained in Miconia for the Flora of Guatemala.

There are no doubt other synonyms but these are the essential ones for North America, where I have seen specimens from Mexico, British Honduras, Costa Rica and Panama. The species extends southward to Brazil and Bolivia.
De Candolle's combination seems valid for this plant for he gave a basionym based on Linnaeus, even though the bibliographic refer- ence was in error and the plants which he had in hand may have represented other than the Linnaean species. Dr. Gleason, in his recent account of the family for the Flora of Panama, used the name Miconia mucronata (Desr.) Naudin for this species.
Miconia humilis Cogn. in DC. Monog. Phan. 7: 764. 1891.
This species, first collected in Guatemala by Scherzer, has most often been considered to be a synonym of M. lauriformis (which see, below, for comment). In the Flora of Guatemala this name will be used for the relatively small plant with small leaves and the nerves arising well above the base. It has been collected rarely in Guate- mala and adjacent Mexico but is often very common in the oak-pine forests of the highlands of Honduras. It is known also from the high mountains of El Salvador.
Miconia laevigata and its allies in Guatemala: There are de- scribed from Guatemala four species closely allied to Miconia laevi- gata (L.) DC. and perhaps not really distinct. Miconia laevigata (L.) DC. is the oldest name in the complex; the leaves are obtuse or rounded at the base and 3.5-8 cm. broad. Miconia hyperprasina Naudin is very similar, but the leaves are acute or subacute at the base. Miconia ochroleuca Standl. is essentially the same as M. hy- perprasina but the type has smaller, relatively simple inflorescences. Miconia virescens (Vahl) Triana seems to belong to the same group but I have seen little material and none of it authentic.
The four species are maintained in the Flora of Guatemala al- though it is felt that they are too much alike.
Miconia lauriformis Naudin, Ann. Sci. Nat. ser. 3, 16: 189. 1851.
We have a photograph of Linden 1279 and a fragment of Linden 64-9, the original collections of this species from Mexico, which seem to indicate that the species is exceedingly close to M. mexicana (Humb. & Bonpl.) Naudin. The species found in Chiapas, Guate- mala, El Salvador and Honduras to which this name has been applied

seems to be distinct and perhaps should be referred to M. humilis Cogn. See that species (above) for further comment.
Miconia Lundelliana L. Wms., sp. nov.

Folia anguste ovata vel ovata, acuta, basim rotundata vel cordata, breviter petiolata, 5-plinervia, subtus furfuracea; inflorescentia termi- nalis, dichasialia, parviflora; hypanthium campanulatum vel subglobosum; calyx 6-appendiculatum, coriaceum; petala late oblanceolata, acuta, subcarnosa.
Small trees, branches slender, terete or slightly flattened when very young, obscurely pubescent with small, glandular, peltate scales, becoming glabrous;

Miconia Lundelliana is not closely allied to any continental North American melastome known to me. However, there are several in the West Indies to which it is related, mostly those which have been described in the genus Pachyanthus A. Rich, and of these it is per- haps most closely related to P. mantuensis Britton & Wilson. In South America there are at least two related species, Pachyanthus corymbiferus (Naud.) Cogn. and Miconia larensis Gleason (which might well have been placed in Pachyanthus by a less conservative botanist) .

In his work cited above, Aublet published two names for this plant — one name in part of the copies and another name in the others. In the same work (2 : 659, t. 268. 1775) he published another Tamonea in the Verbenaceae. It seems probable that he "discov- ered" that he had described two genera with the name Tamonea and changed one of them while the work was going through press. It seems quite clear that he changed the name of the Melastome to Fothergilla mirabilis and that he should be followed in this. Indica-
WILLIAMS: TROPICAL AMERICAN PLANTS, V 575
tive that his intent was this is that the name Tamonea guianensis does not appear in the index of scientific names but Fothergilla mira- bilis does — as F. admirabilis.
The only North American specimens of this common South American plant which I have seen are cited below.

There can be no question that these specific names, maintained by Cogniaux in his revision of the Melastomaceae under both Mi- conia and Tococa, refer to but a single species. Dr. Gleason has often determined the species with the two names, depending on geo- graphical origin. The species does point up again, if this need be done, the difficulty of distinguishing some genera in the family.

Gleason, Standley, Lundell and others. In the Flora of Guatemala only M. prasina will be included. Miconia pteropoda Benth., origi- nally described from British Guiana, is excluded and the problem of whether or not it is a synonym of M. prasina, which is the oldest name for the taxon occurring in Central America, is left to the spe- cialists.

When Standley and I described this species as a Miconia we overlooked its previous publication in the genus Tococa. The spe- cies is not a Tococa as that genus is usually delimited, and it would seem to go best into Miconia. The genus Calycogonium A. DC. con- tains some species related to this, but that West Indian genus may not be distinct from Miconia, and I feel that this species should be left in Miconia until that generic complex can be critically studied.
Known from Guatemala, El Salvador and Honduras.
Monochaetum (A. P. De Candolle) Naudin, in Central America, is a small genus of several closely allied species. In order to put those of Guatemala in order it was necessary to look at all of those described from Mexico, Central America and Panama. Those from South America were studied, but apparently no species overlap. Monochaetum was revised by Cogniaux (DC., Monog. Phan. 7: 391-405. 1891) and those of North America were reviewed by Gleason (Am. Journ. Bot. 16: 586-594. 1929). Gleason later (1938) added two species, and Standley and Steyermark (1944) added one, to this genus. Those found in Guatemala, with their synonyms, follow:

The geographical range of the species is from Mexico, through Central America, and Panama. The species is a variable one and perhaps could be divided into two varieties but these would then
WILLIAMS: TROPICAL AMERICAN PLANTS, V 577
be difficult to define. The species as I would define it is practically the same as it was defined by Cogniaux in 1891, except that many more specimens are available and show two taxa maintained by Cogniaux to be the same.

The range is southern Mexico, Guatemala, and Nicaragua. The species is quite variable and it is curious that it has not been seg- regated.
Monochaetum tenellum Naud. Ann. Sci. Nat. ser. 3, 14: 159. 1850.
The species is apparently endemic to Guatemala. It is closely allied to M. Deppeanum but apparently can be distinguished con- sistently by larger size, longer petiole on leaves, and non-barbellate pubescence.
Monochaetum guatemalense Standl. & Steyerm. (Field Mus. Bot. 23: 136. 1944) is a synonym of Heterocentron elegans (Schlecht.) Kuntze.
Rhynchanthera De Candolle is a small but distinctive genus to which four North American species have been ascribed. In verify- ing the single species credited to Guatemala I had occasion to look at most of the material available in the larger American herbaria. There follows a key to the species that I have seen and bibliography and comment concerning them. Alfred Cogniaux prepared a good revision of the genus more than 70 years ago (in DC. Monog. Phan. 7: 97-111. 1891) and accounted for 35 species, all South American except one.

A species widespread in the tropical lowlands. It occurs in Mexico, but only one specimen has been found in Central America although it should certainly be found along the Atlantic lowlands of most of the region. The species is found in the lowlands of all the northern South American countries and extends southward into the Amazon basin. It is quite possible that R. insignis Naudin be- longs here as a synonym. I have seen the following North American specimens of the species:

I know nothing of this species. Cogniaux (in DC. Monog. Phan. 7: 105. 1891) places it as a synonym of R. mexicana DC., but Cog- niaux' concept of the species is obviously a mixture and this reduction should be verified. It is more likely to be a synonym of R. grandiflora.

This species is based on a drawing in the De Candolle herbarium (Chicago Natural History Museum Neg. 30660) in turn based on a Sesse" and Mocino specimen that could be the one from which the drawing was made; it is numbered 1211, which number also appears on a field label in red crayon. There is a duplicate of this specimen in Chicago as well as a photograph of Sesse" & Mocino's sketch of Thenardia rosea. Cogniaux (in DC. Monog. Phan.) apparently did not see the De Candolle drawing or the Sesse" & Mocino material or drawing for he placed the species in the wrong group of the genus. Gleason (Ann. Mo. Bot.

Dr. Wurdack has called my attention to the fact that there seems to be no difference between the abundant northern South American Tibouchina aspera and T. belizensis from our region. So far as I know, the species is recorded from only two localities in British Honduras, and nowhere else in North America. The disjunct range is of interest but not unusual.
There is in our herbarium a fragment from the Aublet herbarium which may have come from the type collection.
Tibouchina bipenicillata (Naud.) Cogn. in Mart. Fl. Bras. 14 (3): 385. 1885; in DC. Monog. Phan. 7: 243. 1891.
This species ranges from Costa Rica to Venezuela and Colombia. Standley (Field Mus. Bot. 18: 840. 1938) credited T. Mathaei Cogn. to Costa Rica. The specimens which he had available are rather T. bipenicillata.
The only other closely related species in Central America is T. aspera Aubl., mentioned above.
Tibouchina longifolia (Vahl) Baill. Adansonia 12: 74. 1877. Rhexia longifolia Vahl, Eclog. Amer. 1 : 39. 1796. Tibouchina Bour- gaeana Cogn. in DC. Monog. Phan. 7: 264. 1891. T. aliena Brande- gee, Univ. Cal. Publ. Bot. 6: 58. 1914.
Tibouchina longifolia is the common, occasionally abundant, and widely distributed Tibouchina of Central America. It is in the West Indies as well and extends as far south as Bolivia. It occurs in most natural habitats, except the driest and coldest, and its elevational range is from 150 to some 2000 meters. It is an occasional weed in cultivated ground or in second growth.
The species is variable, and for the Flora of Guatemala I have included in it plants with the connective of the anther to more than 1 mm. long; those with anthers of two sizes in a flower; and those having almost no connective to those with some connective on sta- mens with larger anthers. Pubescence is from dense to rather sparse, appressed or spreading; the calyx lobes from about 3 mm. long to as much as 15 mm.; the petals from perhaps as little as 5 mm. long to 15 mm. or perhaps more.
Without passing on the validity of Tibouchina Schiedeana (Cham. & Schlecht.) Cogn. (in DC. Monog. Phan. 7: 261. 1891) and of T.
WILLIAMS: TROPICAL AMERICAN PLANTS, V 581
Naudiniana (Dene.) Cogn. (in DC., I.e. 264), which were both de- scribed from Mexico above the Isthmus of Tehuantepec, the Central American material determined with these names by Gleason, Stand- ley, myself and others is being redetermined as T. longifolia.
Tibouchina longisepala Cogn. var. longisepala. T. longi- sepala Cogn. in DC. Monog. Phan. 7: 259. 1891.
A fairly distinct species among those of Central America. It occurs in the mountains of the western departments of Guatemala and may be expected in the Mexican state of Chiapas. The type collection is Bernoulli & Cario 2872, which I have not seen.
Tibouchina longisepala var. spathulata (Brandegee) L. Wms., comb. nov. T. spathulata Brandegee, Univ. Cal. Publ. Bot. 6: 58. 1914.
The variety spathulata is distinguished from variety longisepala by having the hairs of the stems and the branches widely spreading and not appressed as in the typical variety. All of the specimens seen originated along the Mexico-Guatemala border in the state of Chiapas and the departments of San Marcos and Quezaltenango.
Topobea Aublet is a small but interesting and difficult genus ranging in North America from Mexico to Panama, where 25 species have been reported or described. A greater number are reported from South America. The genus is very closely related to Blakea P. Br., and in fact the distinction between the two is rather tenuous. In Topobea the anthers are elongated, either linear or lanceolate and attenuated at the apex, while those of Blakea are short, oval or oblong and obtuse at the apex. It is difficult to place a given specimen in its genus if stamens are missing, as they often are. In Topobea there seem to be two groups — one in which the anthers are connate and with the connective produced dorsally into an appendage, the other in which the anthers are apparently free at anthesis and the con- nective is without a dorsal appendage.
The following is an account of those species of Topobea which I am able to distinguish, occurring from Mexico to the San Juan de- pression in Nicaragua.
Calyx truncate, with or without external dentiform appendages near the margin;
bracts one-third to one-half the length of hypanthium and calyx. Bracts about one-third as long as hypanthium and calyx; axils of main leaf veins without coarse, weak hairs T. laevigata.
582 FIELDIANA: BOTANY, VOLUME 29
Bracts about half as long as hypanthium and calyx; axils of main leaf veins below with a few coarse, weak hairs T. calycularis.
Calyx prominently 6-dentate; bracts about half as long as hypanthium and calyx.
Three principal veins separating well above base of leaf; bracts of outer pair divided about half way to base T. calycularis.
Three principal veins separating at or very near base of blade; bracts of outer
pair free nearly to base.
Outer bracts longer than inner pair; inflorescence, bracts and hypanthium furfuraceous pubescent T. Watsonii.
Outer bracts equaling inner ones; bracts glabrous or pubescent.
Petioles with a tuft of hairs at juncture with blade; leaf blades mostly about 20 cm. long; hypanthium glabrous T. Maurofernandeziana.
Petioles without hairs at juncture with blade; leaf blades mostly about 9 cm. long; hypanthium obscurely furfuraceous T. Standleyi.
Topobea calycularis Naudin, Ann. Sci. Nat. ser. 3, 18: 149. 1852; Cogn. in DC. Monog. Phan. 7: 1090. 1891.
GUATEMALA: Johnston 1849 (F); Skutch 1845 (F, NY); Standley 89832 (F, NY), 89973 (F), 91228 (F), 91704 (F), 92672 (F); Steyer- mark 44834 (F, NY), 48727, 48912 (F); Tuerckheim 1135 (F, NY), 1688 (F); Wilson 178, 199, 360 (all F).
The species occurs in Guatemala in a rather restricted area in the west central part of the country. The name has been used for most of the kinds of Topobea which occur in the area. The differ- ences between this species and T. laevigata seem to be rather minor and it is possible that additional material will show them to be the same.
Originally described from Mexico. I have not seen Mexican ma- terial and accept the species as Cogniaux treated it.

The only specimens with definite localities we have are from Vera Cruz as are those which Cogniaux cited (DC. Monog. Phan. 7: 1090. 1891), and that from British Honduras. The Mexican specimens cited in old literature and credited to Pavon as Blakea trinervia are no doubt those of Sesse" and Mocino who possibly intended to name
WILLIAMS: TROPICAL AMERICAN PLANTS, V 583
their collection Blakea trinervia L. There are four sheets of this spe- cies in the Sess£ and Mocino herbarium, now all given the same number (1812) but surely from two different collections, for the original field numbers seem to be 11-1 and 12-1. One of these (12-1) bears the name "Blakea trinervia ic.," the other (11-1) bears the same name with two additional letters (m) inserted in the generic name before the final a but without the indication "ic." However, on the same sheet is another original label with the name changed to Spanish phonetic spelling, followed by the indication "ic."

There is some question whether the two names given above really belong to the same species but until this genus has been revised I prefer to place them together.
The species is known from Mexico and Costa Rica. I have seen only two collections from our range and so far as I know they are the only collections of the genus from the Pacific slope of North America above Costa Rica. In Costa Rica the species is reasonably abundant.
Topobea Standleyi L. Wms., sp. nov.
Arbores vel frutices usque ad 8 m. Folia elliptica vel ovalia, longe petiolata, acuminata; inflorescentia uni-biflora; pedunculus crassus, usque ad 1 cm. longus; calyx coriaceus, urceolatus, 6-dentatus; petala subrhombica vel ovato-subrhom- bica, acuta, carnosa; connectiva inappendiculata.
Small trees or shrubs to 8 m. tall, the branches stout, obtusely tetragonous or subterete, glabrous or nearly so; leaves elliptic to oval, glabrous or the petiole obscurely puberulent at first, long petiolate, abruptly acuminate, the blade 4.5- 15 cm. long, 1.5-10 cm. broad (mostly about 9X4 cm.), cuneate or acute to the base, 5-nerved, the lateral pair very obscure, secondary nerves diverging at about 80°, the petiole 1.5-4 cm. long, slender; inflorescence 1-2 short pedicellate flowers in the axils of upper leaves; flower with short fleshy pedicels 1 cm. long or less, the subtending bracts minutely furfuraceous, two opposed pairs, the outer pair ovate, as long as or slightly longer than the inner pair, about 5 mm. long, divided to the base, the inner pair free and truncate or rounded; hypanthium and calyx coriaceous, obscurely furfuraceous, about 7-8 mm. long, the hypanthium urceo- late, the calyx regularly 6-dentate, somewhat flaring; petals subrhombic or ovate- subrhombic, acute, fleshy, obscurely retrorse-ciliolate, to 7 mm. long and 5 mm. broad; stamens apparently free, the anther about 5 mm. long, the filament a little shorter, the connective lacking dorsal appendage.

Standley and Gleason have both given manuscript names to the collections cited above but neither has published a name. The spe- cies seems to be distinct and it is with pleasure that I name it for Standley.
Perhaps most closely related to T. Watsonii, a species of wet, low forests. It is distinguished by the thick branchlets, the short thick and fleshy pedicels, difference in shapes of both pairs of bracts, and other details.

NICARAGUA: Englesing 116 (F).
The isotype of this species in the Gray Herbarium is a mixture of Topobea Watsonii Cogn. and of Blakea bella Standl. Steyermark 41681 is almost identical to the portion of the collection which is a Topobea.
Triolena Naudin and Diolena Naudin. The species of these two genera are very much alike in general appearance but are separated by stamen characters that would seem to be trivial — certainly not of generic worth. Diolena, if separated from Triolena, has two basal spurs on the connective of the anther and the leaves of each pair are dimorphic. Triolena has three basal spurs on the connective, at least on the larger anthers, and the leaves of each pair are isomorphic or dimorphic.
In the preliminary manuscript of the Flora of Guatemala, Paul Standley has indicated that "it is probable that the two groups should be united," although he did not carry out the suggestion. There seems to be no justification to maintain the two generic names and as they were published at the same time and as the taxa contain about an equal number of entities, Triolena Naudin is selected as the name to be kept and Diolena Naudin is reduced to synonymy.

HALORAGACEAE Gunnera
There have been described from Mexico and Central America five species of Gunnera. The first of these, described as Pankea insignis by Oersted in 1857 from Costa Rican material, is the oldest and is now well known from Costa Rica and Panama. Hemsley, in the Biologia Centrali-Americana, included G. insignis and a second undescribed species from Vera Cruz in Mexico. Schindler, in his review of Haloragaceae in Pflanzenreich, added G. Wendlandii Reinke ex Schindler, which is probably a synonym of G. insignis. Schindler apparently saw only four collections of the genus for North America and these all from Costa Rica. In 1922, Brandegee de- scribed G. mexicana, which is unknown to me except for the rather short description. In 1940, Dr. Lundell described G. Killipiana from Volcan de Tacana on the Guatemalan-Mexican border and it is to this species that all of our Guatemalan and Honduran material will be referred in the Flora of Guatemala. Weber and Mora more re- cently (1958) have described G. talamanca from Costa Rica. This comes from the known range of G. insignis, but in the field, where I saw it a few months ago, it appears quite distinct.
Proserpinaca
There is but a single species of Proserpinaca in Central America and adjacent Mexico. Dr. N. C. Fassett has annotated most of our Central American material as P. palustris var. crebra Fernald & Griscom but it seems not "abundantly" distinct from the typical variety.
