STUDIES OF AMERICAN PLANTS— IV

PAUL C. STANDLEY

The numerous and extensive collections of tropical American

plants received for study by Field Museum during 1929 and 1930

have continued to yield a high number of undescribed or otherwise

interesting species. Some of these are discussed on the following

pages.

The plants other than Rubiaceae that are treated here are chiefly

Central American. Most of them are British Honduran, and were

collected by C. L. Lundell and William A. Schipp. The plants

obtained by these collectors include the usual number of novelties,

and several genera new to Central America, such as Rousselia,

Suriana, and Thespesia.

Several new species found by the writer in Honduras in 1927-28

are described, the most interesting being a member of the genus

L/udwgia, a group not recorded previously from Central America.

A few species are based upon collections made in Panama twenty

years ago by H. Pittier, and submitted recently for determination to

Field Museum by the United States National Museum. Several

other new plants are from collections made lately in the state of

Veracruz, Mexico, by that discriminating collector, Dr. C. A. Purpus.

His recent explorations show that Veracruz is not completely known

botanically, in spite of the vast amount of work already done there.

The present paper includes, also, a few new names and combina-

tions necessary for observance of the generally accepted rules of

nomenclature, or for saner or more conservative treatment of genera.

By far the greater number of the succeeding pages are filled with

descriptions of new South American Rubiaceae, a group to which the

writer has devoted much time during recent months. The material

treated in this paper is from four principal sources. Through the

courtesy of Dr. L. Diels and Dr. K. Krause, there have been received

for study from the Berlin Botanic Garden more than 700 undeter-

mined Rubiaceae, chiefly of the tribes Coussareae and Psychotrieae.

These include a substantial number of new species from Brazil and

Andine South America besides many extensions of range for those

133

already published. Several sendings of plants from the Jardin Princi-

pal Botanique of Leningrad have contained additions to the list of

Rubiaceae known at present from Colombia. Most of these addenda

were collected by Dr. G. Woronow and S. Juzepczuk in the little-

known Caqueta region of southern Colombia, whose flora shows such

affinities with that of Amazonian Peru as might naturally be expected.

The majority of the new Rubiaceae described are Peruvian. A

large number of them are from the magnificent collection made in

eastern Peru in 1929 for Field Museum by Llewelyn Williams. This

collection, the first really large one assembled in that particular

region, was made in localities not visited, apparently, by the classic

collectors, such as Poeppig, Spruce, and Ule. It has proved unex-

pectedly rich in new species, besides providing material of others not

represented hitherto in American herbaria. It includes numerous

described species and some genera not reported before from Peru.

A second large Peruvian collection of Rubiaceae is that obtained

in 1929 by E. P. Killip and A. C. Smith for the Smithsonian Institu-

tion. A nearly complete set of duplicates of the Rubiaceae has been

deposited in Field Museum through the courtesy of the United

States National Museum and the unicates have been lent for de-

termination. Most of the specimens were gathered in localities other

than those visited by Mr. Williams, consequently the species repre-

sented are largely different. The Killip and Smith series has yielded

a very large number of additions to the flora of Peru.

Study of this huge amount of new material has been facilitated

to an extraordinary extent by the series of type photographs obtained

at Berlin in 1929-30 by J. Francis Macbride. This work, the most

important from the standpoint of American systematic botany that

has ever been undertaken, was planned by 'Dr. B. E. Dahlgren,

Acting Curator of the Department of Botany in Field Museum. It is

being carried out through a grant generously made for the purpose

by the Rockefeller Foundation. Botanists long accustomed to poring

over confused Latin descriptions and trying to guess whether the

specimen in hand could possibly be the species described, can best

understand the joy of having all at once before one's eyes photo-

graphs of a vast number of species previously lacking in American

herbaria. By this means the task of determination is simplified

almost incredibly, and the improvement in accuracy of determi-

nations scarcely can be estimated.

Unless otherwise indicated, all the specimens cited on the succeed-

ing pages are in the herbarium of Field Museum.

COMMELINACEAE

Campelia hirsuta, sp. nov. — Herba erecta valida c. 60 cm. alta

simplex, caule sparse hirsute vel glabro, internodiis brevibus saepe

vaginis occultis; folia oblongo-oblanceolata 14-20 cm. longa, 4-5.5

cm. lata, abrupte longeque acuminata, basin versus longe angustata

et distincte petiolata, utrinque dense hirsuta; vaginae subinflatae c.

1 cm. longae, ubique sed praesertim ad marginem densissime pilis

longis patentibus fulvis hirsutae; pedunculi foliis plerumque longiores,

saepe superne bifidi, dense fulvo-hirsuti, bractea una ad vaginam

nudam reducta supra medium onusti; flores pauci, c. 3-4, capitati,

bracteis 2 valde inaequalibus fulcrati; bractea major late ovali-ovata

4.5-6 cm. longa, 2-3.5 cm. lata, abrupte acuta, basi truncata vel

subcordata, viridis, utrinque dense hirsuta, minore 1.5-3 cm. longa

Honduras: Lancetilla Valley near Tela, Dept. Atlantida, altitude

about 300 m., January 7, 1928, Paul C. Standley 54189 (Herb. Field

Mus. No. 582,994, type). Also Nos. 52994 and 53957, from the

same region.

By recent writers a single species of this genus, Campelia Zanonia

(L.) HBK., has been recognized, but the present plant is so different

from that that it scarcely can be considered as even an extreme form

of it. C. hirsuta differs conspicuously in its copious pubescence of

long stiff hairs, and in the very distinct form of the floral bracts.

Tradescantia gracillima, sp. nov. — Herba gracilis adscendens

vel procumbens, ad nodos radicans, caulibus elongatis ramosis in uno

latere minute denseque papilloso-pubescentibus, internodiis elongatis;

vaginae 4 mm. longae subadpressae, minute praesertim ad marginem

pubescentes; folia ovata vel elliptico-oyata 3-5 cm. longa, 1.5-2 cm.

lata, acuta, tenuia, basi valde inaequalia et saepe in petiolum breyem

contracta, supra sparse pilis longis debilibus pallidis paucicellularibus

villosa, subtus pallidiora, glabra; umbellae terminales pauciflorae,

pedicellis gracilibus 4 mm. longis glabris; bracteae 2 (vulgo basi

folio 1 fulcratae) late rotundato-cordatae, apice rotundatae, basi

abrupte contractae, extus sparse villosae vel fere glabrae, virides;

sepala late ovata obtusa 2.5-3 mm. longa ciliata; petala alba 4 mm.

longa; ovarium glabrum. — Honduras: In wet thicket near Tela,

Dept. Atlantida, at sea level, January 27, 1928, Paul C. Standley

55158 (Herb. Field Mus. No. 583,293, type). Also Nos. 54540 and

56609, from the same locality.

The plant is clearly related to T. commelinoides R. & S., a Central

American species, which has much longer and proportionately nar-

rower leaves, purplish flowers, and comparatively narrower bracts.

T. gracillima may be the plant described by Clarke (in DC. Monogr.

Phan. 3: 296. 1881) as T. commelinoides var. rotundifolia.

altitude 30 m., December, 1927, Paul C. Standley 53891 (Herb.

Field Mus. No. 583,868, type).

A well-marked form, with much more abundant pubescence than

any of the other specimens of this species which are available for

comparison.

URTICACEAE

Rousselia humilis (Sw.) Urban. — On the North American

continent this weedy plant has been known heretofore only from

Yucatan. A recent collection makes possible its inclusion in the

Central American flora: British Honduras: Honey Camp, October,

1929, C. L. Lundell 552.

ARISTOLOCHIACEAE

Aristolochia Mexiae, sp. nov. — Frutex scandens, caulibus novel-

lis gracilibus subgeniculatis plus minusve angulatis viridibus, minute

tomentellis yel subglabratis, internodiis brevibus vel elongatis; folia

breviter petiolata alterna, petiolo crassiusculo 1-1.5 cm. longo dense

pilosulo-tomentoso; lamina subcoriacea oblonga vel elliptico-oblonga,

interdum ovato-oblonga, 17-21 cm. longa, 7-9 cm. lata, acuta vel

subobtusa, basi profunde cordata, sinu petiolum aequante vel paullo

longiore lobis late rotundatis clause, supra viridis, pilis minutis

adpressis sparse pilosula, ad venas densius pilosula, venis pallidis

prominulis, subtus pallidior, ubique subdense pilosulo-tomentosa, ad

venas dense pilis brevibus pallidis subadpressis pilosula, basi 7-nervia,

costa crassiuscula elevata, neryis lateralibus utroque latere c. 7,

angulo acuto adscendentibus, leviter curvis, gracilibus, elevatis, prope

marginem conjunctis, nervulis arctissime reticulatis prominentibus;

pedunculi axillares 1-2-flori 4-6 cm. longi, bracteis ovalibus vel

ovali-ovatis apice obtusis vel rotundatis 2-4 cm. longis basi breviter

cordatis; calyx extus sparse adpresso-pilosulus vel glabratus, stra-

mineus, intus nigro-purpureus, utriculo subgloboso c. 6 mm. longo,

fauce ampliata, limbo 3.5-4.5 cm. longo profunde in lobos 3 lineari-

attenuatos fisso; capsula anguste oblonga sparse tomentosa acuta basi

attenuata, c. 6.5 cm. longa et 1.3 cm. crassa. — Mexico: San Sebastian,

Jalisco, alt. 1,500 m., on southern slope of open pine forest, February

13, 1927, Ynes Mexia 2772 (Herb. Field Mus. No. 605,722, type).

The foliage of this plant is very similar to that of A. asclepiadi-

folia Brandeg., of Mexico, but the calyces of the two species are quite

different. The plant is more closely related to the Mexican A.

malacophylla Standl.

Aristolochia maxima L. var. cordata, var. nov. — Folia anguste

oblonga, 7.5-13 cm. longa, 2-3.5 cm. lata, acuta vel abrupte acuta,

basi profunde cordata, sinu angusto 10-14 mm. longo, lobis basalibus

STUDIES OF AMERICAN PLANTS 137

paullo incurvis late rotundatis, utrinque ad venas puberula, aliter

fere glabra; capsula c. 6.5 cm. longa, 4.5 cm. longe stipitata. —

Panama: Shores of Gatun Lake south of the laboratory, Barro

Colorado Island, August 28, 1929, W. N. Bangham 455 (Herb.

Arnold Arb., type).

The leaves of A. maxima are normally obtuse or rounded at the

base, or very shallowly cordate, and in none of the numerous speci-

mens available do the leaves approach closely in form those of this

Panama plant. It is not improbable that flowers, when collected,

may show that this Barro Colorado Aristolochia represents a distinct

species.

OLACACEAE

Heisteria fatoensis, sp. nov. — Frutex vel arbor omnino glabra,

ramulis gracilibus, yetustioribus interdum brunnescentibus, novellis

olivaceis subangulatis, internodiis brevibus vel elongatis; folia petio-

lata, petiolo gracili 7-9 mm. longo supra breviter canaliculate; lamina

crasse membranacea oblongo-ovata vel interdum elliptico-oblonga,

7.5-9.5 cm. longa, 3-4.5 cm. lata, subabrupte et longiuscule acumi-

nata, acumine angusto attenuate summo apice anguste rotundato et

mucronato, basi plerumque late rqtundata, fere concolor, nervulis

supra prominulis et laxe reticulatis, costa subtus elevata gracili,

nervis lateralibus utroque latere c. 6, tenuibus, fere rectis, prope

marginem arcuato-conjunctis,. nervulis prominulis reticulatis; flores

in axillis fasciculati, pedicellis gracilibus 3-7 mm. longis petiolo

brevipribus; calyx c. 0.5 mm. longus, breviter 5-lobus, lobis trian-

gularibus acuminatis sub flore patentibus; petala 5 fere 2 mm. longa

oblongo-ovata acuta, intus prope medium villosa; stamina 10; pedi-

celli fructiferi c. 7 mm. longi; calyx fructifer paullo accrescens,

reflexus, ut videtur viridis, 4 mm. longus, subinteger vel brevissime

undulato-lobatus; fructus globosus &-10 mm. diam. ruber, apice

late rotundatus. — Panama: Loma de la Gloria near Fat6 (Nombre

de Dios), Prov. Colon, alt. 100 m. or less, July- August, 1911, H.

Pittier 4244 (Herb. Field Mus. No. 599,422, type).

The collector states that the plant is a woody vine, but it is more

probable that it is an erect shrub, like other members of the genus.

The species is well marked by the very small fruiting calyx and by

the globose fruit.

Heisteria concinna, sp. nov. — Arbor fr-9-metralis omnino gla-

bra, ramulis gracilibus subteretibus olivaceis, novellis subteretibus

mm. longis petiolo duplo brevioribus teretibus; calyx in anthesi 1

mm. longus ad medium 5-lobus, lobis triangulari-ovatis acuminatis

erectis; petala 5 acuta, 2 mm. longa, intus prope medium breviter

Guanacaste, 600 m., Standley & Valeria 46353.

Called "naranjillo" in Costa Rica. Growing there in dry forest; a

tree with smooth bark and dense rounded crown; fruits white; fruiting

calyx dark red.

By its coriaceous leaves and white fruits this is easily recognized

among the few Central American members of the genus.

POLYGONACEAE

Coccoloba cardiophylla Standl. Field Mus. Bot. 8: 8. 1930.

This well-marked species was described from Yucatan. Recently

it has been discovered to be a member also of the Central American

flora, having been collected in near-by British Honduras: Honey

Camp, September, 1929, C. L. Lundell 514-

STUDIES OF AMERICAN PLANTS 139

Evidently a relative of the widespread C. Schiedeana Lindau, but

differing conspicuously in its very broad leaves, somewhat suggestive

of those of the common seagrape, C. Uvifera.

RAFFLESIACEAE

This family has been discovered in Central America only recently,

Apodanthes Flacourtiae Karst. having been found in 1927 on Barro

Colorado Island, Canal Zone (see Field Mus. Bot. 4: 149. 1929). A

second representative of the family may now be recorded for Central

America :

Pilostyles mexicana (Brandeg.) Rose. Apodanthes mexicana

Brandeg.

Honduras: Near Siguatepeque, Dept. Comayagua, alt. 1,100 m.,

February, 1928, Paul C. Standley 56221 , growing on Calliandra lucens

(Britton) Standl. The Pilostyles was abundant on this host, and was

easy to recognize, even at some slight distance, after it once had been

found, because of the tuberculate appearance given to the branches

of the Calliandra by the dense clusters of flowers.

ROSACEAE

Amelanchier denticulata (HBK.) Koch. — So far as I know,

this genus has not been known heretofore from Central America, but

it may now be recorded from Guatemala: San Juan Sacatepequez,

alt. 1,480 m., in 1929, Jesus Morales Ruano 1375. The vernacular

name is given as "cerezo rojo."

Apparently an ally of P. Kellermanii P. Wilson.

SIMARUBACEAE

Suriana maritima L. — This shrub, common in some portions of

the West Indian region, has not been reported, so far as I know, from

Central America. The following collection is at hand: British

Honduras: Stann Creek, in open places along the beach, a shrub

1.5 m. high, December, 1929, W. A. Schipp 508.

STUDIES OF AMERICAN PLANTS 141

MALPIGHIACEAE

Stigmaphyllon ciliatum (Lam.) Juss. — Although known from

the West Indies, this species has not been reported to occur on the

North American mainland. Specimens are now at hand, as follows:

British Honduras: Stann Creek, in mangrove swamp, a woody vine

4.5 m. long, with a stem 2.5 cm. in diameter, the flowers yellow,

December, 1929, W. A. Schipp S59.

SAPINDACEAE

Thouinidium decandrum (H. & B.) Radlk. — In the Trees and

Shrubs of Mexico (Contr. U. S. Nat. Herb. 23: 708. 1923) this species

is reported only from western Mexico. Two recent collections extend

its range substantially within that country: Rancho Remudadero,

Veracruz, April, 1929, C. A. Purpus 13042, 14078.

MALVACEAE

Thespesia populnea (L.) Soland. — This species is one of those

plants frequent in many parts of the West Indies which always may

be expected to occur in Mexico and Central America, but there is no

available record of its occurrence there. The following collection is

probably the first report for Central America: British Honduras:

Stann Creek, at edge of mangrove swamp, a shrub 3 m. high, with a

trunk 10 cm. in diameter, the capsules yellow, December, 1929, W.

A. Schipp 505.

This plant appears to be most nearly related to H. longipes

(Dowell) Standl. and H. glaber (Dowell) Standl., both of which are

Mexican, but they are conspicuously different in the form of their

leaves, which are acute or long-attenuate at the base.

The species is named for Wilson Popenoe, director of the Lan-

cetilla Experiment Station. This Begonia is a handsome one, and

well worthy of cultivation. It somewhat resembles B. nicaraguensis

Standl., but the latter differs at first glance in its coarsely toothed

leaves, which have an altogether different pubescence.

Although known previously only from Panama, having been

described from the Canal Zone, recent collections show that this

species has a wide range. The following specimens agree well with

type material: Honduras: Lancetilla Valley near Tela, Dept. Atlan-

tida, near sea level, Standley 52713, 54144; a slender shrub 1-2 m.

high, often reclining; fruit red or violet, borne on naked branches

below the leaves. — British Honduras: Middlesex, in jungle, alt. 60 m.,

It was quite unexpected to find in Honduras a member of this

North American genus, which is almost confined to the United States.

No true species of the group, apparently, is known from either Central

America or Mexico. L. hondurensis is clearly a relative of L. virgata

Michx., of the southeastern United States, the latter differing con-

spicuously in its relatively broader leaves, large petals, broader sepals,

and very small epigynous disk.

This species, of which only a single individual was found, in spite

of prolonged search, bears no very close resemblance to any other

Eryngium of which I have seen material. It is noteworthy for its

slender sedgelike habit, long narrow leaves, and small slender flower

spikes.

In his monograph of the genus Clavija (in Engler's Pflanzenreich)

Mez reports from the lower Amazon Valley a single species, C. serrata

(Hoffmansegg) Mez, a plant with serrate leaves. The present plant

does not agree in floral details with any of the species which he lists

from other regions.

At the request of Dr. B. E. Dahlgren, this species is named for

Snr. Bento Chermont, of the Museu Goeldi, to whom Field Museum

is indebted for generous assistance during the Marshall Field

Amazon Expedition in 1929 especially in connection with the photo-

graphing of the many type specimens contained in the Museu Goeldi's

52: 104. 1917.

Whether the genus Diateinacanthus is a valid one, the writer is

not prepared to decide, but it was so considered by Lindau, who did

some of the best and some of the worst work upon the American

Acanthaceae. The herbarium of Field Museum possesses a photo-

graph of the type specimen, in the herbarium of the New York

Botanical Garden, collected at Puerto Sierra (now Tela), Honduras,

in 1903 by Percy Wilson, No. 129. Through the courtesy of Dr.

B. L. Robinson, there has been examined also the type specimen of

STUDIES OF AMERICAN PLANTS 151

Odontonema paniculiferum Blake, which is clearly conspecific. It was

collected in forest near Manatee Lagoon, British Honduras, in

January, 1906, M. E. Peck 278.

The following recent collections of this plant may be cited:

leaves, lack of pubescence, exceptionally long and leafy calyx-lobes,

and very long corolla lobes. It resembles the Peruvian M. leucantha

Krause, which has much shorter calyx lobes.

The collector's notes read : "Frutex arborescens 8-pedalis pulcher-

rima; flores aurei. An Chelone?" The shrub must be a handsome

one because of its profuse, rather large flowers. The general effect

in the dried specimens reminds one somewhat of certain species of

the genus Loranthus and its allies. The foliage is strikingly suggestive, .

also, of that of the genus Vallesia.

The genus Syringantha evidently is a close relative of Exostema,

of the tribe Cinchoneae, but the corollas are conspicuously different

in the two genera. In Exostema the corolla lobes are elongate,

often very much so, narrow, and usually spreading or even recurved.

The collector's notes state that the plant is a shrub of four to

five feet, the very fragrant white flowers with the odor of jasmine.

Bouvardia Karwinskyi is one of the most clearly distinct species

which I have ever had occasion to describe. It is evidently a relative

of B. longiflora (Cav.) HBK., but the only member of the group

centering about that species with which it could be confused is B.

erecla (DC.) Stendl. The latter is similar only in having narrow

leaves, but they are only 5-16 mm. long, and the calyx lobes are

merely 2.5-6 mm. long. In habit the two species are quite unlike,

and they bear little general resemblance to each other. The dense,

very long and narrow leaves of B. Karwinskyi, and the long corollas,

give the whole plant an aspect which reminds one strongly of some

species of the genus Amsonia.

The species is easy to recognize because of the abundant pubes-

cence of coarse, stiff, spreading, ferruginous hairs.

Ferdinandusa Paxii Winkl. Repert. Sp. Nov. 7: 249. 1909.

The species was based on material collected at San Antonio,

near Mapiri, Bolivia, and it is represented by several collections

from that country. A recent collection from Peru is referable to the

same species: Peru: Mishuyacu, near Iquitos, Dept. Loreto, alt.

This species, if it be distinct, is the second of the genus, the other

being T. condamineoides Karst., of Venezuela. So far as I know, no

description of T. pauciflora has been published, and the parenthetical

citation of Solereder by Schumann (1. c.) is unexplained. Probably

the reference is to an herbarium name.

This plant belongs to the group Laniflorae (see N. Amer. Fl. 32:

45. 1918), which is characterized by a terminal narrow thyrsoid

spikelike inflorescence, but in all the species previously ascribed to

the group the corolla is variously pubescent outside, rather than

glabrous, as in this plant. The type specimen is annotated by

Hemsley, and determined as "Gonzalea sp." It was so listed by that

author (Biol. Centr. Amer. Bot. 2: 32. 1881), with the data "Humid

forests of Zulusuchiapas." The incorrect locality data must have

been taken from a label with some other specimen of the same number,

since the proper locality name is written rather plainly upon the

label which I have seen, nor is there any mention of "humid forests."

STUDIES OF AMERICAN PLANTS 161

The plant does bear some general resemblance to the genus

Gonzalagunia (of which Gonzalea is a synonym), but evidently it

is referable rather to Rondeletia. In that group it is noteworthy for

the complete absence of pubescence.

The type material is decidedly fragmentary, but the characters

exhibited are such as to leave no room for doubt that a very distinct

new species is represented. It is easy of recognition because of the

very long and narrow calyx segments.

This species is noteworthy for the very large and broad leaves,

with chiefly spreading pubescence. It is related to G. panamensis

Related, evidently, to P. perumana Standl., which has similar

leaves and flowers. In that species, however, the petioles are much

shorter, the stipules larger, and the lateral veins of the leaves less

numerous.

In publishing this species, its country, through some oversight,

was given as "Peru." The Rio Pastasa, however, lies in a region

which usually is admitted to be a part of Ecuador. The specific

name is, therefore, markedly inappropriate, but there is apparently

no authority for changing it to some more fitting one.

This plant might be referred to R. formosa (Jacq.) Schum. var.

longi flora Schum., which was based upon Peruvian material. In

that, however, the corolla is densely pilose outside, and the leaves are

much smaller and relatively broader. The present plant can scarcely

be considered a mere variant of R. formosa, for it differs greatly from

the usual forms of that species in its much elongate and narrow leaves

and in its extraordinarily elongate corolla. It is probable that var.

longiflora also deserves specific rank.

In most characters this plant agrees with the descriptions of G.

described from Peru. I have seen no material certainly referable to

either of these species, in which the petioles are described as being

very short. The species are described as differing also in various

minor characters, and it seems necessary, for the present at least, to

consider the plant here described as representing a different species.

tinctive. The species does not seem to have a close resemblance to

any other listed for Brazil.

The available specimen is in poor condition for study, consisting

of a leafy branch with only a detached portion of an inflorescence.

of the Guianas, of which I have seen no specimens. The leaves of the

Guiana plant are described as glabrous, and the heads as terminal.

The present plant belongs to the group called Trichocephalae by

Mueller in his treatment of the genus Psychotria in Martius' Flora

Brasiliensis, a group which seems to be well represented in the Guianas

and neighboring Brazil. This species bears some resemblance to the

recently described Cephaelis surinamensis Standl. (Field Mus. Bot.

4: 335. 1929), but in that the broader leaves are rounded or subcordate

at the base, and their pubescence consists of stiff hairs. C. tontane-

oides resembles also C. horridula (Muell. Arg.) Standl. (1. c.), of

Brazil, but in that the heads are sessile.

barcellana Muell. Arg. in Mart. Fl. Bras. 65: 369. 1881.

The type was collected by Spruce along the Rio Negro in Brazil,

and the species is reported also from southern Venezuela. Apparently

it has a wide distribution, as the specimens cited below show. The

species, if it be a valid one, is exactly like C. tomentosa (Aubl.) Vahl in

general appearance, but it may be recognized by the fact that the

copious hairs along the lower surface of the midrib are all closely

appressed, rather than spreading almost at right angles, as in C.

tomentosa.

The material at hand is unsatisfactory, since two of the specimens

are sterile, and the other bears only a single imperfect inflorescence,

but there is no doubt regarding the relationship of the plant. It is

related to P. polyphlebia Bonn. Smith, a Costa Rican species, which

is not similar to any other member of the genus that I have seen.

P. polyphlebia differs from the Peruvian plant in having much more

numerous veins in the leaves, which are conspicuously hirsute beneath.

The plant is a member of Mueller's section Bracteosae of the sub-

genus Eupsychotria (see Mart. Fl. Bras. 65: 273. 1881). From all the

species of that group it differs prominently in the long and narrow,

sessile leaves with broad bases. It must be a showy species when

growing because of the numerous large and brilliantly colored bracts.

It is difficult to suggest a relationship for this well-marked species.

Its most striking character is found, probably, in the diminutive

corolla.

Although this species has an unusually broad area of distribution,

it has been impossible to find any published name which seems to

relate to it. The recently collected specimens evidently are identical

with the Peruvian specimen existing in the Berlin herbarium, whose

label bears the unpublished name of Ruiz employed here.

Psychotria microbotrys is not closely related to any other species of

which material is available. In habit it suggests rather strikingly

various species of Palicourea, but in flower structure it appears to be

better referable to Psychotria. The large stipules, thyrsiform panicle,

and very small fruits offer distinctive characters.

The plant bears some resemblance to P. hylocharis Standl.,

described from Colombia. It is related also to P. tenuicaulis Krause,

a native of Peru. The latter differs in its short-petioled leaves with

broad bases and in the presence of pubescence on the stems and leaves.

is not a Palicourea rather than a Psychotria. I have not been able to

Psychotria stenostachya appears to be a member of the small

subgenus Nonatelia, which is distinguished by its 5-celled fruit. This

species is closely related to P. Tessmannii Standl., described recently

from Peru, but that differs in having a narrow thyrsiform panicle,

which is comparatively loosely flowered, rather than a spikelike

inflorescence. Spruce 4383, listed above, was cited at the time of

publication of P. Tessmannii as representative of that species, but

the ample material obtained by recent collectors proves that two very

well marked species are involved.

The species was based upon three Brazilian collections, Glaziou

the fruit, but a specimen from the Berlin herbarium ("Ex herb.

Eichler") collected by Glaziou, without number, date, or definite

locality, bears mature fruit. This is globose or ellipsoid, 7 mm. long,

glabrous, rounded at base and apex, nearly smooth, and crowned by

the large persistent calyx. The two pyrenes are broadly rounded on

the back, and plane on the inner surface but very shallowly and

narrowly sulcate longitudinally.

The genus Psychotria is so large that there is some excuse for over-

looking earlier published specific names, but it is rather curious that

Mueller in the Flora Brasiliensis should have proposed the name

Psychotria Gardneriana for two distinct species (the other is a Pali-

courea). He rejected the earlier name nuda for this species because

he considered it inappropriate.

Tobagoa maleolens Urban, Repert. Sp. Nov. 14: 343. 1916.

Diodia Ottonis Schum. ex Pittier, PI. Usual. Venez. 338. 1926.

There is at hand a photograph of a specimen of a Venezuelan

plant, from the Berlin Herbarium, bearing the annotation by Schu-

mann "Diodia Ottonis, ex affinitate D. strictae Miq." Specimens

collected in Venezuela by Pittier and sent to Berlin for determination

236 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. VIII

have been distributed under the same name. This plant is evidently

identical with that described by Urban from Tobago under the name

Tobagoa maleolens. Tobagoa has not been reported hitherto from

Venezuela. The following specimens have been seen by the writer:
