The sequence of genera follows that of Engler and Prantl in ‘‘Die natiirlichen Pflanzenfamilien’’. Ponthieva Turckheimii Schlechter in Fedde Re- pert. 8 (1906) 47, as Ponthiea Tiirkheimit. Ponthieva graciliscapa Schlechter in Fedde Repert. Beihefte 19 (1923) 166. It appears that the Costa Rican Ponthieva gracili- scapa is conspecific with the Guatemalan P. Tiirckheimiu as shown by a careful comparison between the types of the two concepts. The type of the latter species is de- scribed as rather taller than P.graciliscapa, but another Guatemalan collection of P. Tiirckheimu has quite the measurements of P. graciliscapa. It is noteworthy that the altitude where each type was collected is nearly the same, and especially that the flowers of the two concepts are practically identical. One Costa Rican collection of this species (an im- mature plant) is only about 21 em. tall with the smallest leaf-blade measuring about 3 cm. long and 1.38 cm. wide. [1] Liparis tipuloides ( Lindl.) Schlechter in Fedde Repert. Beihefte 19 (1928) 91. Microstyls tipuloides Lindley in Ann. & Mag. Nat. Hist. 15 (1845) 256. Malaais tipulodea O. Kuntze Rev. Gen. Pl. 2 (1891) 673. Liparis eustachys Schlechter in Fedde Repert. Bei- hefte 19 (1923) 91. i agree with Schlechter that the species described as Microstyls tipuloides should be transferred to the genus Liparis, for, although it has an abbreviated column, the anther appears to be opercular and incumbent as in Lip- aris and not erect as in Malaxis. Although Microstylis tipuloides originated in Colom- bia (Popayan), it was reported in 1866 from Costa Rice (near San Miguel) by H.G. Reichenbach. As aresult of Ridley’s rather misleading description of Microstylis tipuloides in his monograph in Journ. Linn. Soc. Bot. 24 (1888) 382, Schlechter erected Liparis eu- stachys declaring that his new species doubtless repre- sented Reichenbach’s Costa Rican record of Microstylis tipuloides. Schlechter’s statement that the leaves of the latter species are shorter and narrower than those of the Costa Rican form is not borne out by an examination of a photograph of typical Microstylis tipuloides. In this record the leaves are approximately similar to those de- picted in a drawing of the type of Liparis eustachys of which the supposedly shorter inflorescence is quite im- mature toward the apex. The flowers of each species ap- pear to be of nearly the same size and form, with the exception that in Microstylis tipuloides the lip is repre- sented as acuminate, whereas in Liparis eustachys it is shown as acute. Pleurothallis obliquipetala Acura & Schwein- Surth sp. nov. Herba minima, caespitosa, muscicola. Radices fibro- sae, numerosae. Caules minuti, filiformes, maxima pro parte vaginis scariosis celati. Folia oblanceolata, acuta vel obtusa, inferne sensim angustata. Inflorescentia perbrevis. Flores singuli vel bini. Sepala petalaqgue membranacea. Sepalum dorsale peranguste lanceolatum, longe acumin- atum, trinervium. Sepala lateralia ovato-lanceolata, a- brupte longe acuminata, parte inferiore connata. Petala oblique rhombico-lanceolata, acuminata. Labellum ling- ulatum, basi lobulato-dilatatum, apice late rotundatum ; discus medio bicarinatus, parte superiore papillosus. Plant minute, caespitose, together with mosses form- ing a dense mat. Roots numerous, fibrous, flexuous, gla- brous, as stout as the sheathed stems. Stems up to about 5 mm. long, filiform, monophyllous, mostly concealed by three imbricating loose tubular scarious sheaths. Leaves oblanceolate to obovate, obtuse or acute, gradually nar- rowed into a slender petiole, up to 11 mm. long and 3.4 mm. wide when expanded, commonly conduplicate and apparently very fleshy in the living state. Inflores- cence very short. Flower solitary or two, large for the plant, membranaceous; perianth segments apparently subparallel. Dorsal sepal very narrowly lanceolate, long- acuminate to an obtuse tip, about 5.1 mm. long and 1.6 mim. wide near the coneave base, 8-nerved with the nerves carinate dorsally. Lateral sepals ovate-lanceolate, con- nate for the basal third, rather abruptly long-acuminate, about 5.2 mm. long, 8-nerved with the inner nerves short and indistinct and the two outer nerves prominent and earinate dorsally, each free portion about 2 mm. wide. Petals asymmetrically rhombic-lanceolate with the an- terior margin dilated, acuminate, about 2.6 mm. long and 1 mm. wide in the middle, 1-nerved, irregularly [3 ] crenulate above the middle on the anterior margin. Lip lingulate, lobulate-dilated on each side near the base, ses- sile, broadly rounded at the apex, 8-nerved, slightly cren- ulate above, about 3.5 mm. long, 2 mm. wide near the base, about 1.6 mm. wide near the apex; dise papillose above the middle especially toward the apex, with a pair of low slightly converging keels near the middle. Column about 2 mm. long, uniformly membranaceous-winged above the base; rostellum suborbicular, convex, decurved. A collection of this species in the herbarium of the New York Botanical Garden ( Shafer 9048 ) is apparently in a more advanced condition than the type, for it has generally longer leaves (reaching 23 mm. in length) and very mature perianths on the summit of the ovoid ovaries. The nearest ally of P.obliquipetala appears to be P. semperflorens Lind|. which differs in having elongate pe- duncles, and about twice smaller flowers with broader dorsal sepal, dissimilar petals and different lip. Vegeta- tively it suggests P. bicristata Cogn., P.calcarata Cogn., P.cryptantha Cogn. and P.mornicola Mansf. Pleurothallis obliquipetala was sent and tentatively described (but not published) by Dr. J. Acuna of Santiago de las Vegas, Cuba. Cusa: Province of Oriente, Estribo del Este, Pico Turquino. Au- gust 1, 1935. J.Acuta 9540 (Tyrer in Herb. Estacién Central Agro- nomica, Santiago de las Vegas, Cuba; Dupiicare Type in Herb. Ames No. 46830); Oriente, Gran Piedra.

In an interesting collection of Costa Rican orchids sent by Manuel Valerio, there is a specimen referable to this species. It apparently differs from the type in sever- al particulars. The inflorescence is terminal only (not [ + | lateral and terminal), the sepals are 5-nerved rather than 8-nerved, the petals are acute rather than acuminate and the subquadrate lip (which is scarcely pandurate when expanded) is about 10 mm. long from the auricles of the deeply cordate base and about 12 mm. wide below the middle. The ovary appears to be definitely fusiform. Cosra Rica: La Palma. At 1500 meters altitude. ‘‘Flor blanque- cino-verdosa’’, November 1937. Manuel Valerio 2480, Oncidium cabagrae Schlechter in Fedde Repert. 9 (1911) 292. Oncidium Rechingerianum Kriinzlin in Engler Pflan- zenreich IV. 50, pt. 2 (Heft 80) (1922) 202, fig. 18 C, a-c. A drawing of the habit with a floral analysis of Oncid- tum cabagrae made under the supervision of Dr. Schlech- ter shows no appreciable differences from O. Rechinger- zanum as illustrated by a photograph of the type and a floral analysis (l.c.) made by Dr. Krinzlin. Slight differ- ences consist in the somewhat smaller leaves and nodding upper part of the raceme of O. Rechingerianum. A flower from the type of O.cabagrae (kindly sent by Dr. R. Mansfeld of Berlin) seems to resemble not only the analysis of typical O. Rechingerianum, but also a large series of Costa Rican specimens referred to that species. In this flower the dorsal sepal appears to be somewhat smaller than specified for O.cabagrae and to approach in size that of O. Rechingerianum. Moreover, the callus at the base of the lip appears to be reduced to an oblong thickening extended into an apical pair of lobules thus differing from the typical form of O. Rechingerianum. Apparently O.cabagrae is a rather variable species with the variation shown in the size of the plant, the breadth of the leaves, the strictness of the inflorescence, the size of the floral segments, the lobing of the callus [5] on the lip and the degree of lobing of the column-wings. It appears to be frequent in Costa Rica and occurs in the Province of Chiriqui, Panama. Oncidium obryzatoides Avrdnzlin in Engler Pflan- zenreich LV. 50, pt. 2 (Heft 80) (March 1922) 240. Oncidium fulgens Schlechter in Fedde Repert. Bei- hefte 17 (December 1922) 83. Oncidium varians Schlechter in Fedde Repert. Bei- hefte 19 (1928) 151. Oncidium Brenesu Schlechter in Fedde Repert. Bei- hefte 19 (1928) 257. A photograph of the type of Oncidium obryzatoides in the Ames Herbarium shows that this species differs from the description in having flattened-ovoid rather than oblong pseudobulbs and in having the lateral lobes of the lip triangular-ovate or semioblong and auriculate instead of linear and retuse. A drawing of Oneidium fulgens made under the su- pervision of Dr. Schlechter together with specimens said to represent the type collection indicate that this concept is scarcely separable from O.obryzatoides. From the lat- ter species, O. fulgens appears to vary in having some- what narrower leaves, less prominently produced lateral lobes of the lip, more sharply lobulate callus on the lip and column-wings which are obtuse at the base. How- ever, these tendencies are present in otherwise typical forms of O.obryzatoides. Oncidium varians, of which there is an example of the type number in the Ames Herbarium, differs from typ- ical O.obryzatoides in having more elongated pseudo- bulbs and leaves. The callus on the lip appears to be very similar to that of O. fulgens, and the base of the column- wings is either acute or obtuse. Oncidium Brenesu, judging trom analyses made from [6 ] the type, appears to be only a small, few-flowered form of O. obryzatoides. Its pseudobulbs are rounder, and its inflorescence is a simple few-flowered raceme. The parts of the flower, however, do not show any morphological differences from those of O. obryzatoides. It appears to me that O.angustisepalum Kriinzl. (in Engler Pflanzenreich IV. 50, pt. 2 (Heft 80) (1922) (208) is a Closely allied plant and is possibly conspecific, as shown by a floral analysis; but this species was described from an inflorescence only, and the basal portion of the lip appears to be considerably narrower than that of O. obryzatoides. Two other allies of O. obryzatoides appear to be O. sclerophyllum Krinzl., which has about twice smaller flowers, and O.tetraskelidion Kriinzl., which is described and drawn as having acute or acutish sepals and petals, and is said to have the lateral lobes of the lip linear. Oncidium obryzatoides apparently is a polymorphic species both vegetatively and florally. At one extreme are small plants about 10 cm. tall with elliptical leaves and 1- or 2-flowered racemes, while at the other extreme are large luxuriant plants up to 75 ecm. tall with oblong- ligulate leaves and spreading many-flowered panicles. Florally the variation extends from spatulate-oblong pet- als about 1 em. long and 4mm. wide to broadly oblong- obovate petals about 1.4 em. long and 9.5 mm. wide; the lateral lobes of the lip are more or less well-developed ; the apical portion of the lip ranges from about 1 cm. to 2 cm. in width; the basal callus of the lip is now distinct- ly 5- (or more) lobulate with three distinct apical teeth and now obscurely lobulate with only two distinct apical lobes. It is altogether a most variable species in which similar parts may vary in the same flower! Dichaea Morrisii Fawcett & Rendle in Journ. Bot. [7] 48 (1910) 107; FI. Jam. 1 (1910) 189, t. 80, fig. 81-86. Dichaea Bradeorum Schlechter in Fedde Repert. Beihefte 19 (1928) 154. The description of Dichaea Bradeorum together with a habit drawing and floral analysis of that concept made at Berlin show that it is referable to D. Morrisu of which I have seen the co-type (Hardware Gap, Jamaica, G. /. Nichols). Dichaea Bradeorum, to be sure, is said to possess smooth sepals, whereas those of D. Morrisi are minutely but clearly ciliolate under the hand lens. The outline and proportions of the lip appear to be very similar in both concepts. Asa matter of fact, the sepals and petals of D. Morristi seem to be rather more acuminate than those illustrated in Fl. Jam. t. 80 and thus to approximate those of D. Bradeorum. In the Costa Rican specimens examined (in all of which the sepals are more or less ciliolate), there appears to be considerable variation in the degree of acumination of the parts of the perianth as well as in the prominence of the lateral lobules or auricles of the lip. The latter vary from elongate faleately triangular-linear lobes to short bluntly triangular projections. Jamaica: Mt. Moses. At 3500 feet altitude. On trees. Flower- ingin July.

The description of the Jamaican Cymbidium murica- tum of Swartz and the diagnosis of Dichaea muricata by Fawcett and Rendle state that the flowers are glabrous or else make no mention to the contrary. However, ina very large series of specimens which I take to be un- doubtedly referable to this species, the sepals are usually more or less verrucose on the dorsal surface but occasion- ally appear to be smooth. This character, therefore, seems to be variable or evanescent, and not to be of diagnostic weight. [9] The Costa Rican Dichaea ovatipetala differs from ty p- ical D.muricata in having sparingly subverruculose se- pals, somewhat broader petals and a minutely papillose- ciliate margin on the basal portion of the lip. Though I have been unable to examine any Jamaican specimens of D.muricata, a flower of that species from Guadeloupe shows both the sparsely verruculose sepals and the mi- nutely ciliate base of the lip. The breadth of the petals appears to be a variable character, but in no flower of D. muricata Which | have examined could they be called ‘linear’, as described by Kriinzlin in his monograph of Dichaea (in Engler Pflanzenreich LV. 50 (Heft 88) (1928) 87). The Costa Rican Dichaea similis is scarcely to be distinguished from D.ovatipetala save by its somewhat narrower petals, smooth basal margins of the lip and rather longer and more acuminate lateral lobules or au- ricles of the lip. However, I have seen one Costa Rican specimen ( Quiros 260 = 240) in which one petal is much broader than the other, with the papillose-ciliate base of the lip as in D.ovatipetala, but having long slender lateral lobes of the lip, as in D. similis. Another Costa Rican species, Dichaea verrucosa, has larger flowers than those of D.ovatipetala and D. similis, but is otherwise precisely similar to a combination of those concepts. In this connection it seems advisable to correct some statements made in the type description of Dichaea vagi- nata Reichb.f. ex Kriinzl. (in Engler Pflanzenreich LV. 50 (Heft 88) (1923) 42) and thus to eliminate this species from the puzzling alliance of D.muricata. In his deserip- tion Kriinzlin (l.c.) says: ‘‘ovarium setosum, capsula bre- viter tamen, densissime echinata. ’’ However, a note ona record of the Endres collection from the Reichenbachian Herbarium which must be regarded as the type says: [ 10 | ‘Ovary glabrous.’’ Since a major cleavage in Dichaea is commonly made on the condition of the ovary, it results that D.vaginata is removed from the category of D. muricata. In addition, Krinzlin states in his description of the lip of D.vaginata: ‘‘lobulos ... divergentes non retrorsos’’; whereas he draws these lobes as strongly re- trorse in his floral analysis (l.¢. p. 48, fig. 4 D, a-c) and, moreover, they are pictured as retrorse in the record of the Endres collection. Other species which appear to be closely allied to D. muricata and which may be found to be variants of one polymorphic species are Dichaea Acostaer Schlitr., D. costaricensis Schlitr., D.neglecta Schltr. and D.oxyglossa Schltr. Dichaea muricata is apparently a widely distributed and variable plant (both vegetatively and florally) and extends from the West Indies and Guatemala to Brazil. Dichaea Powellii Schlechter in Fedde Repert. Bei- hefte 17 (1922) 90. Dichaea Brenesu Schlechter in Fedde Repert. Bei- hefte 19 (1928) 264. The description of Dichaea Brenesi, supplemented by a habit drawing and floral analyses of that species made at Berlin, shows that it should be regarded as a synonym of D. Powellii. For separation from D. Powell, Schlechter relied on the longer leaves of D. Brenesii and its supposedly dis- similar lip. However, in aspecimen of the type number of D. Powellii in the Ames Herbarium, the narrowly linear leaves are up to about 8.5 cm. long and 5 mm. wide (well within the range of size of the leaves in D. Brenesit) and the lip approaches that species very closely. Indeed the floral parts assigned to D. Brenesu, even with their measurements, appear to be a close approximation to [11 ] those of D. Powell. Rather than the term ‘‘oblong’’, however, as used in the description of the sepals and petals of both species,the term ‘‘ovate-lanceolate’’ would be more applicable to the acute sepals, and ‘‘elliptic- ovate’? a preferable term for the petals. Moreover, the lateral angles of the lip are short and obtuse rather than ‘‘acuminate’’ as credited to D. Powellia. The only appreciable differences between the two con- cepts seem to be that the ligule on the column of D. Brenesii is described and drawn as linear and the flowers are noted as yellowish, whereas in J. Powell the ligule appears to be rather short and triangular while the sepals and petals are noted as yellow-greenish and the lip a deep blue. Honpuras: Department of Cortes, Santa Cruz de Yojoa.

VII BY Oakes AMES Two sPpEcIES OF STELIS from Costa Rica receive at- tention here, one a member of the section characterized by stigmatic lobes on the gynostemium, the other a mem- ber of the section in which the stigmas are more or less confluent beneath the triangular rostellum. Both species were collected by Alexander F. Skutch. Krom our present knowledge of the orchid flora of Middle America, Stelis is preponderantly Costa Rican. With the addition of the species described below, the genus is now known to be represented in Costa Rica by forty-two species. Stelis planipetala Ames sp. nov.

Leaf 6-13 cm. long, about 1 em. wide, nar- rowly oblong-lanceolate, conspicuously tridentate at the apex with the middle tooth subulate and exceeding the somewhat larger lateral ones; lamina contracted toward the sulcate, slender base. Raceme 8-11 cm. long, borne on a slender elongated paucibracteate peduncle. Bracts of the raceme obliquely infundibuliform, 1-1.5 mm. long, about 2 mm. apart. Pedicels exceeding the bracts, slen- der, somewhat nodding. Flowers pale green, 3-4 mm. in diameter. Lateral sepals ovate-elliptic, about 2 mm. long, 1 mm. wide, 3-nerved, glandulose on the inner sur- face. Dorsal sepal similar. Petals 1 mm. long, hardly 1 mim. wide, subquadrate, imperceptibly if at all thickened at the apex, obscurely apiculate, l-nerved. Labellum about 0.75 mm. long, cucullate, obscurely apiculate with a thickened septum below the middle. Column equalling the petals with the stigmatic processes elliptical and lat- erally produced. Stelis planipetala, in the structure of the labellum, resembles S.cucullata Ames. The glandulose sepals and the imperceptibly thickened one-nerved petals serve to distinguish it.

Leaves including the slender sulcate base 10-13 em. long, about 1 cm. wide, coriaceous, narrowly oblong, tapering at base and narrowed toward the apex, bilobu- late with an apicule betwe -n the lobules. Raceme 11-16 em. long, slightly exceedii.y the leaf. Peduncle sheathed at base by a conduplicate, acute sheath which is 12 mm. long and about 4 mm. wide when spread out. Bracts of the raceme about 2 mm. long, 4 mm. apart, or the lower- most ones almost contiguous, obliquely infundibuliform, equalling the pedicels of the nodding flowers. Pedicels about 4mm. long, smooth. Flowers twenty-five to fifty, vinous-purple when dry. Lateral sepals about 4.5 mm. long, 2 mm. wide below the middle, ovate-lanceolate, apiculate, sparsely glandulose on the inner surface, 3- nerved, on the outer surface distinctly carinate along the mid-nerve. Dorsal sepal 6 mm. long, 2 mm. wide, oblong- lanceolate, apiculate, 3-nerved with the middle nerve lightly if at all carinate. Petals scarcely 1 mm. long, 1 mm. wide, flabellate, much thickened above the middle, 1-nerved. Labellum 1 mm. long, about 0.5 mm. wide, linguiform with an obscure acute lobule on each side near the middle, 3-nerved, quadrate-thickened below the mid- dle, minutely glandulose near the base, lightly concave [21 ] on the upper surface, slightly narrowed above the middle, rounded at the apex. Column equalling the petals, sim- ilar to the column of S. Standleyi Ames. Stelis Skutchi is closely allied to S.Standleyi, differ- ing from it chiefly in the dissimilarly proportioned sepals and lip. It is noteworthy that the dorsal sepal in S. Skutch is strikingly unlike the lateral sepals, being ob- long-lanceolate rather than ovate-lanceolate. In the same locality where the type was found, Dr. Skutch discovered a single plant in a more advanced state of maturity. The flowers of this single specimen are iden- tical with those of iS. Shutchiu, but the vegetative parts show differences. For example, the plant is 80 cm. tall and the leaves are from 1.4—2 cm. wide, borne on second- ary stems which attain a length of 11 em. S. Shkutchii is a member of the alliance to which S. rubens Schltr. belongs. Costa Rica: Vara Blanea de Sarapiqui, north slope of Central Cordillera. At 1500-1750 meters altitude. On fallen tree.

[22 ] A NEW CAMPYLOCENTRUM FROM THE DOMINICAN REPUBLIC BY Oakes AMES THE SARCANTHINAE of the West Indies consist of several genera in which some of the species are aphyllous and in flower-structure call to mind the Old World spe- cies of Angraecum and its allies. An altogether puzzling species of this alliance has been received from the Dom- inican Republic where it was collected by L. Ariza Julia near Ia Romana. The flowers are angraecoid in appear- ance, resembling somewhat the flowers of Mystacidium distichum, yet they exhibit the distinctive characters of Campylocentrum, differing from the known West Indian species in having an elongated slender spur. From spec- imens preserved in alcoho! the roots appear to have been greenish and doubtless possess chlorophyll as is true of species of Taeniophyllum, exercising the functions asso- ciated with foliar structures. The abbreviated stems are concealed by the mass of these roots from among which the flower-shoots emerge. Krom the specimens examined it would seem that the flowers open in succession, only one flower being expanded while the succeeding ones are still in bud. Campylocentrum Ariza-Juliae Ames sp. nov.

Sxurcu there has been received a rather distinct Costa Rican species of the genus ‘Teli- pogon collected in 1937 at Vara Blanca de Sarapiqui. From a casual examination of the flowers, it would seem that this species is identical with 7°. parvulus as described by Charles Schweinfurth in 1937 in the fourth volume of the Botanical Museum Leaflets. But on close study it becomes quite clear that there are differences between it and 7. parvulus which taken together constitute a new species. The petals and lip are broader, are more decided- ly rhombic than in 7. parvulus, and have fewer nerves; the gynostemium bears elongated setose hairs and is not merely pubescent. Furthermore, the labellum is charac- terized by dark-banded nerves. As originally described, T. parvulus was in part differentiated from its allies by having 9-nerved petals and a 14-nerved lip. In his mono- graph of the genus Telipogon, Fritz Kriinzlin was inclined to regard the number of perianth nerves as a substantial means of differentiation, but from my studies it has be- come evident that the nerves vary from plant to plant of the same species if an abundance of material is available for study, and is consequently an unreliable guide to spec- ificity. Therefore 7’. parvulus should not be separated from 7". setosus by the difference in the number of peri- anth nerves, but rather by the form and color of the petals and lip and by the elongated setose hairs produced by the gynostemium.

Petals sub- quadrate-rhombic, about 3.5 em. long and 2.9 em. wide in the middle, abruptly acute, cuneate toward the base, 15-nerved near the middle, with very obscure reticula- tions, setose near the base inside, very minutely papillose- cilolate especially toward the base. Lip transversely rhombic-ovate, acute with a short dorsal keel, about 2.6 em. long and 3.4 em. wide below the middle, 23-nerved below the middle, minutely papillose below the middle, very minutely cellular-ciliolate especially near the base. Column very short and broad, protuberant on the dise of the lip, finely short-pubescent in front, long-setose in the rear (agglutinated in this specimen). Pollinia four, in two pairs, complanate-obovoid at the broadened apex of a long linear stipe. Viscid disc linear-oblong, circinnate. Telipogon ampliforus has apparently no near allies in Central America, but there are several similar species in South America. It differs from the Ecuadorian 7". aureus Lindl. in having broader leaves, dissimilar transversely ovate lip, and many more nerves in the petals and lip. It varies from the Colombian 7'duwbius Reichb.f. (which was described from a flower only) in having a larger flower with broader petals and lip, and purplish (not white) hairs on the column. It diverges from the Peru- vian 7’. Papilio Reichb.f. (apparently a very nearly allied species) in having considerably larger flowers and differ- ently proportioned lip. Costa Rica: Province of San José, northeast of El Copey. In dense oak and bamboo forest near Laguna de la Escuadra. At 2000- 2200 meters altitude. On tree. Flowers pale yellow with dark purple veins.

It appears certain that the Central American Pleu- rothallis divexa is referable to the West Indian P. Ur- baniana. The range of the species, as at present known, extends from Costa Rica and probably Panama to Gua- deloupe and Porto Rico. As to the color of the flowers, Cogniaux (l.c.) says of the Porto Rican plant: ‘‘F lores albidi, intense rubro- striati.’”> One specimen of P. Urbaniana from Guade- loupe (H.Stehlé 1295) shows the flowers yellow. How- ever, the Costa Rican P.divewa has the flowers maroon- purple, purple-red, or “‘hyaline, purple marked. ’’ [ 36 ] CaMBRIDGE, MaAssacHuseETTs, JUNE 30, 1938 BOTANICAL MUSEUM LEAFLETS HARVARD UNIVERSITY ZEUXINE STRATEUMATICA IN FLORIDA BY OaKkES AMES THE OCCURRENCE of the Asiatic Zeuxine strateumat- ica in Florida was reported in Orchidologia Zeylanica 4 (1937) 89. This report was based on a single colony found on January 17, 19387,in a nursery, the Ormond ‘Tropical Gardens, at Ormond in Volusia County. It was sug- gested that this orchid might have been introduced with nursery stock, but convincing evidence for such an in- troduction was lacking and efforts to substantiate it met with failure. Records of Zeuaxine strateumatica having been cultivated in American gardens have not been found. It is not an orchid of horticultural significance and to my knowledge has never been cultivated in our botanic gardens. Shortly after the discovery of Zeuaine strateumatica at Ormond, my attention was directed to a photograph representing several plants of this species collected by George Nelson on January 27, 1936, west of Fellsmere in Indian River County. These plants, unlike those found at Ormond, grew at a distance from cultivated ground. In January, 1988, Nelson again visited the Fellsmere area and reported that Zeuaine strateumatica was spar- ingly distributed over a stretch of two miles and was ap- parently spreading. The original colony was a small one although composed of numerous specimens. [ 37 ] | anal VoL. 6, No. 3 In December, 1937, Donovan S. Correll brought to my laboratory for identification an orchid which had been collected by Charles C. Deam, on January 30, of that year, twelve miles southeast of Kissimmee in Osceola County. This proved to be conspecific with the Ormond plants and with those found by Nelson near Fellsmere. Later (February, 1988) Correll sent in additional rec- ords for the occurrence of the species, indicating its pres- ence in Highlands County, Collier County, Hendry County and Glades County. These were localities visited by Mr. Deam. Then Correll reported that specimens had been found on January 22, 1938, by Miss Mary Singel- tary near Kissimmee growing on the edge of a swamp on Johnson Island. ‘These records indicate very clearly that Zewaine stra- tewmatica is already widespread in peninsular Florida and appears to be adapted to Floridian soil and climate. At the season of anthesis, in 1988, there were frosts in Or- mond, but the flowers of the orchid did not show frost- injury although mulberry trees were completely defoli- ated. In January, 1988, I again visited the Ormond Tropical Gardens and found an abundance of specimens. Along the edges of a drainage ditch the plants were numerous, in one case fifteen flowering stalks being found in an area of less than one square foot of ground. Some of these specimens were so luxuriant that the lower part of the stems had become procumbent, a condition I have never observed in plants collected in the eastern tropics. ‘The smallest specimens were hardly 4 cm. tall, one of these bearing a single flower, perhaps being a very young plant blooming for the first time. When I first saw Zeurine strateumatica in lawns of the Ormond Tropical Gardens, I was inclined to believe that it had been introduced from China with seeds of [ 38 | Centipede Grass (Hremochloa ophiuroides). Centipede Grass, now common in Florida as a lawn-grass, was in- troduced in 1917 from regions in China where Zeuxine strateumatica is a native, and the length of time since the introduction of the grass to the United States would seem to be commensurate with the length of time it has taken for the orchid to become naturalized. Protocorms of Zeuxine might well have been distributed with stolons of Hremochloa ophiuroides and in the course of time might have established themselves in favorable locations. But until we discover definite information in this regard con- jecture must of necessity be our only recourse. As efforts to trace the introduction of Zeuaine strate- umatica to Florida have failed, it might seem that this is so because the species has been a native for a very long time; that it is a species with representatives in both hemispheres and comparable in this respect to Hulophia alta and Polystachya luiteola, orchids known for many years to be components of the flora of Florida. On this assumption it would have to be argued that the plant has escaped attention until recently and is just coming to the notice of botanists. To argue thus would be quite just- ifiable if the localities where Zeuaine strateumatica has been found were just now being explored for the first time and were remote from travelled paths and from human habitations and if the plants proved to be confined because of their dependence on special soils to limited areas from which they have been unable to spread. But the simultaneity of the reported discoveries of colonies in widely separated areas near thoroughfares and in the vicinity of human dwellings constitute rather convincing evidence that the species is a recent newcomer rather than a native being noticed for the first time in regions where it has escaped observation for untold decades. In- tensive botanical exploration has been in progress many [ 39 ] years where the species has been found. Where it occurs it exhibits the propensities of a weed and has become amenable to a diversity of conditions, growing in clipped lawns, under shrubs, along ditches, and thriving equally in sun or shade. The behavior of Zeuvine strateumatica is remarkably unlike that of any other orchid I have observed. As is well known, our native terrestrial species are extremely fastidious. With few exceptions they exhibit intolerance of human contacts. Even though we endeavor to supply the delicate balance of soil conditions revealed necessary by scientific research they seem to resent attempts made to cultivate them in our gardens. Zeuaxine strateumatica behaves as if it were adapted to the disturbing influences usually associated with cultivated ground and this was strikingly evident in the Ormond ‘Tropical Gardens where the plants survive the clipping of lawns and the cultivation of the soil beneath shrubs. The roots of the plant are provided with endophytic fungi. From cultures made at the Biological Laborato- ries by John N. Porter, the fungal symbiont would seem to be aspecies of Rhizoctonia with typical monilioid con- idial chains. Attempts to germinate the seeds in associa- tion with this fungus have failed, but failure may be the result of the methods used rather than evidence of in- compatibility. The likelihood that the fungus isolated is a species other than the one on which mycorrhizal asso- ciation depends is of course a possibility. Zeuvine strateumatica is rather unusual in the brevity of its floral maturation in Florida. It comes into flower in January and ina very few weeks sets an abundance of fertile seeds. By the middle of March the withered stems, leaves and inflorescence have completely vanished. In early April | was unable to find a trace of the plant in the Ormond Tropical Gardens and transplanted colonies [ 40 | in my garden at Ormond, with one exception, were with- out a vestige of superterranean parts. In passing it may be emphasized that many terrestrial orchids appear to be prevalently subterranean in their nature, the stems, leaves and flowers being but a brief stage in the devel- opmental history. Noteworthy examples of this are the species of ‘Triphora including 7° trianthophora, and the remarkable Australian species RAizanthella Gardneri and Cryptanthemis Slateri, the latter a small herbaceous saprophyte wholly subterranean with the exception of the flowers which just reach the surface of the ground. It is as if the production of flowers were but an inter- lude in the vegetative life of the plant, something inci- dental to ensure wide distribution of the species. Whether or not the flowers of Zeuxine strateumatica are selt-polli- nated is a question for which the answer is yet to be found, but the rapidity of seed maturation and the abun- dance of fertile seeds (often polyembryonic) may be re- garded as in a measure bound up with the extraordinary rapidity with which the species is becoming established in peninsular Florida.

[ 45 | ORCHID STUDIES, VI BY Louis O. WitLLIAMs THE PRESENT NUMBER In my series of orchid studies contains: (1) a synopsis of the Philippine species of Plocoglottis, (2) a study of the polymorphic Jonopsis utricularioides, (8) a description of a new genus of the Sarcanthinae from the Philippine Islands and (4) three new species of orchids from Borneo. A SYNOPSIS OF THE PHILIPPINE SPECIES oF PLocociorris Blume Six species of the genus Plocoglottis have been de- scribed from material gathered in the Philippine Islands. All of these were described by Ames. An additional spe- cles is proposed in the present paper. Among the seven concepts now accredited to the Philippines five appear to be distinct on the basis of the material | have examined. 1. Plocoglottis bicallosa Ames in Elmer Leafl. Philipp. Bot. 5 (1912) 1571. Plocoglottis bicallosa is quite easily distinguished from its allies by means of the lacerated lip. Although the leaves are usually narrow, this character is of little value because there is a collection available which shows very broad leaves, quite as broad as the leaves of the other Philippine species. This broad-leaved collection bears the following data: ‘‘in forest slopes, Mt. Halcon,’’ Mindoro, At 8000 feet altitude. March 10, 1922. Ramos & Edano 60. 2. Plocoglottis Copelandii Ames in Philipp. Journ. Sci. 2 (1907) Bot. 826. Plocoglottis acuminata Ames in Philipp. Journ. Sci. 2 (1907) Bot.326,nomen nudum in synon.,non Blume. [ 46 ] This is the common and most widespread of the Phil- ippine species of Plocoglottis and was the first member of the genus to be described from Philippine material. 8. Plocoglottis bicomata L.O. Williams sp. nov. Herba terrestris, usque ad 4 dm. alta. Pseudobulbi grandes, quadrifoliati. Folia lanceolata,acuminata, tri-vel multinervia, longe petiolata. Scapus vaginatus, piloso- pubescens sed basi glaber. Inflorescentia laxa; bracteae triangulari-lanceolatae, acuminatae, pubescentes. Sepal- um dorsale anguste oblongum, obtusum, dorso pubes- cens. Sepala lateralia oblongo-ovata, obliqua, obtusa. Petala lineari-lanceolata, acuta. Labellum subquadra- tum, apiculatum, quadricallosum et bicomatum, mar- ginibus lateralibus laceratis. A terrestrial herb up to about 4 dm. tall. Pseudo- bulb (only one seen) large, about 2.5 em. long and 1.5 em. thick, bearing four leaves at its summit. Leaves lan- ceolate, acuminate, with three prominent and several lesser nerves; blade 15-25 cm. long and 2-8 cm. broad; petioles nearly as long as the blades, sheathing the stem at the base. Scape apparently lateral from the base of the thickened pseudobulb, shortly pilose-pubescent, be- coming glabrous below, with several acute sheaths which are reduced to bracts toward the upper portion. Inflores- cence lax, about 2 dm. long; bracts triangular-lanceolate, acuminate, pubescent, about 4-7 mm. long. Dorsal sepal narrowly oblong, obtuse, pilose-pubescent on the back, about 7-nerved, slightly concave, 15 mm. long and 5 mm. broad. Lateral sepals oblong-obovate, oblique, obtuse, slightly concave, pubescent on the back, 7-nerved, about 12 mm. long and 6 mm. broad. Petals linear-lanceolate, acute, glabrous,about 14 mm.long and 8 mm. broad at the base. Lip nearly quadrate when expanded, about 7 mm. long and 8 mm. broad, with an apiculation at the apex [ 47 ] on either side of which is a callus; dise with two ovate or oval callus-like thickenings; on the outer side of each of the terminal calli is a lacerated membrane or coma of coarse hairs; lateral margins of the lip serrated. Column slightly arched, glabrous, 7-8 mm. long. Plocoglottis bicomata is not closely allied to any of the other Philippine species of Plocoglottis. It may be distinguished from all of them by the large pseudobulbs, by the two tufts of hair, by the two large terminal cal- lion the lip and by the two large callus-like thickenings on the dise of the lip. Plocoglottis bicomata appears to be closely allied to Plocoglottis pubiflora Schitr., a native of New Guinea. I have not seen specimens of the New Guinea species, but from the description it seems to be amply distinct. By vegetative characters, Plocoglottis bicomata is not easily distinguished from the other Philippine species, but because of the two patches of pubescence and the two large thickenings on the lip, this is perhaps the most distinctive Plocoglottis known from the Philippines. Luzon: Rizal Province, Paningtingan. March 1915, Loher s. n. (Type in Herb. Ames No. 44335) ; Rizal Province, Sumag. April 1914. Loher s. n. 4. Plocoglottis lucbanensis 4 mes in Elmer Leafl. Philipp. Bot. 5 (1912) 1572. Plocoglottis luchanensis may be recognized without much difficulty by the small distinetively shaped lip and by the compact inflorescence. 5. Plocoglottis mindorensis Ames in Philipp. Journ. Sci. 2 (1907) Bot. 827. Plocoglottis Wenzela Ames Orch. 5 (1915) 101. Plocoglottis McGregorti Ames Orch. 7 (1922) 121. This species appears to embrace a group of rather [ 48 ] variable plants regarding which it is difficult to reach a satisfactory basis for segregation. Indeed, I am not sure that the three concepts cited above should not all be re- ferred to Plocoglottis Copelandii Ames. When the abun- dant material now available is taken into account, there are no characters given in the original descriptions by which these three concepts may be separated. I have been unable to find characters which are constant. LoNopsIs UTRICULARIOIDES, A POLYMORPHIC SPECIES I have recently studied a number of specimens of Ionopsis from South America sent to the Ames Herbar- ium for determination. ‘These specimens raised the ques- tion of the proper specific name for the plant which has generally been named Jonopsts paniculata Lindl.of which the identity has been investigated with the aid of avail- able material. Two species, which I have not seen, from the Cordilleran region of South America, may belong to this complex. These are Jonopsis orchioides Krinzl. in Fedde Repert. 17 (1921) 888 and J. zebrina Kriinzl. in Notizbl. Bot. Gart. Berlin 7 (1920) 435. The former may be a synonym of J.utricularioides, but the latter, if it is well characterized, may prove to be distinct. The synonymy which follows belongs, I believe, to Tonopsis utricularioides, a widespread and polymorphic species. Ionopsis utricularioides (Sw. ) Lindley Coll. Bot. (1821) t. 389A; Gen. & Sp. Orch.
