STUDIES OF AMERICAN PLANTS— III

PAUL C. STANDLEY

The following pages are devoted chiefly to descriptions of new

species of tropical American plants, but there are listed, also, a few

new combinations necessary for conformity with the International

Rules.

Most of the new species described are from one of three principal

sources. Many of them are Venezuelan Rubiaceae, which it was

intended to publish in an enumeration of the plants of that family

occurring in Venezuela, but since the publication of that account

must be delayed for some months, it seems desirable to publish the

new species at the present time.

Many of the plants here described are from Yucatan. Their

diagnoses precede a flora of that region which, it is expected, will

be issued in the near future.

Finally, the present paper contains descriptions of a large

number of apparently new plants discovered in the current collec-

tions received for determination by Field Museum. Most of these

novelties are Central American. A few were collected by the writer

in Honduras in 1927-28, and several were found in the Salvadorean

collections which Dr. Salvador Calderon, with his customary

enthusiasm and diligence, has continued to forward.

The majority of the new Central American species were collected

in British Honduras, a country in which unwonted botanical activity

has developed during the past year. Several were detected in the

northern part of that colony by Mr. C. L. Lundell, whose large

collection of the past season is supplying the first adequate repre-

sentation of the flora of any limited region of British Honduras.

Mr. Lundell's collections have furnished the first records of the

occurrence in Central America of numerous species known pre-

viously only from Yucatan or from more northern parts of Mexico.

The majority of the new British Honduras plants here described

are from the astonishingly rich collection made lately by Mr.

William A. Schipp. He seems to have a genius for discovering rare

plants, or at least those which have escaped the attention of earlier

explorers. Certain species occurring in his series are quite unexpected

discoveries. Some represent substantial extensions of range, and

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

others illustrate species known heretofore only from the original

collection. Particularly noteworthy is the discovery so far north-

ward of the genus Bredemeyera, presumed previously to be confined

to South America, and of a second Central American species of

Quiina, the first having been named from Panama only recently by

the present writer.

Unless indicated otherwise, all the specimens cited on the

succeeding pages are in the herbarium of Field Museum.

PALMACEAE

Acoelorhaphe Wrightii (Griseb. & Wendl.) Wendl. — Originally

described from Cuba, this handsome palm probably occurs also in

Florida and the Bahamas. It may now be added to the flora of

Central America, on the basis of a collection made in British

Honduras, along the Stann Creek Railway, in March, 1929, W. A.

Schipp 93. At first I was inclined to believe that the British Honduras

plant represented a distinct species, but the differences between it

and the Cuban form do not seem to be of specific importance.

Mus. No. 581,781, type). Also No. 54212 from the same locality.

This palm grows only in the deep forest well up on the hillsides

above Lancetilla. It is a slender and graceful plant, much less

offensively armed than most species of the genus.

ORCHIDACEAE

Cypripedium montanum Dougl. — In recent years, in spite of

the extensive collections that have been made in Alaska, very few

species new to the flora of the territory have been found. To the

two species of Cypripedium hitherto known from the region may

now be added this one of altogether different appearance. The data

are as follows: Alaska: Glacier Bay, July 16, 1929, William S.

Cooper & Frances E. Andrews 212. It is remarkable that so showy

a plant should not have been found by some of the numerous col-

lectors who have visited this locality in former years.

This is the first true Coussapoa to be reported from Mexico. A

tree described by the writer under the name of C. Rekoi is stated by

Mildbraed (Notizbl. Bot. Gart. Berlin 10: 413. 1928) to be synony-

mous with Poulsenia aculeata Eggers, of Ecuador.

60 m., September 1, 1929, W. A. Schipp 334 (Herb. Field Mus.

No. 602,917, type).

Since the writer published, in 1917, an account of the Mexican

and Central American species of Ficus (Contr. U. S. Nat. Herb. 20:

1-35), very few new species of the genus have been detected in

Central America. This is remarkable, in view of the fact that

during the past twelve years a great deal of collecting has been

done in the region. Apparently, most of the species of Central

America have been collected.

The present plant does not agree, however, with any of the

species hitherto recorded for Central America. Probably it is

related to F. Colubrinae Standl., but that differs in having smaller

leaves, more or less pubescent, and with only 2-4 pairs of lateral

nerves.

This was indicated as a new species of Loranthus by Dr. Mill-

spaugh, but no description of it has ever been published. The

Yucatan plant is perhaps related to S. diversifolius (Benth.) Standl.,

a little-known species of central Mexico.

The plant is rather similar to H. phanerophlebia Standl., but in

that species, of Salvador, the flowers are glabrous or nearly so, and

the leaves cuneately acute at the base and with distinct venation.

The small leaves recall those of D. acuminata Standl., of Panama,

but in the latter the leaves have long and narrow acuminations and

longer petioles, and the inflorescences are few-flowered and but little

longer than the petioles.

Hymenaea Courbaril L. — If one were to read the description

of Inga megacarpa Jones (Contr. West. Bot. 15: 140. 1929), and

attempt to place the plant by description alone, one would prob-

Courbaril, one of the most common trees of the Pacific coast of

Mexico. The leaflets are, of course, a single pair, as usual, not

"about 5 pairs," as described by the author.

In most characters this plant resembles M. setulosum Pittier,

of southern Mexico. In the latter, however, the leaflets are several

times as large, and the pubescence is different.

At the collector's request, this species is named for Dr. Elmer

D. Merrill.

Cicer arietinum L. — This is a fairly well-known plant,

supplying, as it does, one of the chief foods of the Iberian Peninsula,

the garbanzo or chick-pea. In Mexico, likewise, it is a favorite

food, procurable in any village market, and planted in wide fields,

like beans or maize. It was inevitable that it should attract the

attention of one unfamiliar with the region, yet that is perhaps not

sufficient reason for describing this Old World plant as a new species,

and in a genus other than that to which it really belongs. To the

synonymy of Cicer arietinum must be added the following quite

superfluous name: Ononis crotalarioides Jones, Contr. West. Bot.

A good many species of Byrsonima have been described or

reported from Mexico and Central America, but all or most of them

seem to me to be mere forms of the variable B. crassifolia (L.) DC.

This Yucatan plant, however, is so strikingly different, and so

uniform in its foliage characters, that it seems safe to regard it as

a distinct species.

Dr. Qaumer states that the plant is very showy because of the

deep crimson inflorescences and fruits. Some of the other Mexican

and Central American species also are strikingly handsome when in

relatively shorter and erect outer corona filaments, its elongate

it represents a plant quite unlike that Mexican species. D. brachis-

tanthus is related to D. yucatanensis, but in that the leaves are

deeply cordate at the base, the stems are hirsute, and the appendages

of the corona much more developed.

It is with considerable reluctance that I propose a new species

in this already complicated group of the genus Ipomoea, whose

members are so imperfectly known and so badly in need of critical

revision. The present plant, however, I have been quite unable to

refer satisfactorily to any of the described species. It is related

evidently to I. purpurea (L.) Lam., which usually has pubescent

leaves and glabrous seeds. It differs from I. Meyeri (Spreng.) Don

in its shorter sepals and larger corolla.

Sprague published in 1924 (Kew Bull., 145) a detailed account

of the rather extensive synonymy of this Mexican species, and came

to the conclusion that its proper name was Citharexylum spicatum

(Jacques) Sprague. In making this new combination, however, he

overlooked the fact that a Citharexylum spicatum had been published

by Rusby in 1900 (Bull. Torrey Club 27: 81). I have not seen

material of Rusby's species, but at least until it has been proved to

be a synonym, the specific name spicatum can not be used for the

Mexican plant, and the latter should, therefore, be known as Citha-

rexylum Pringlei Greenm.

while in this Yucatan plant there is no trace of gland-tipped hairs

about the inflorescence.

of appreciation of his excellent monograph of the Mexican species

of Salvia, which has proved invaluable to all students of the Mexican

flora.

The Columneas are among the very handsomest of all the plants

of Central America, but most of the species of the region are con-

fined to the mountains of Costa Rica and Panama. Only a few

extend to northern Central America and Mexico, and the present

plant seems to be an isolated species, somewhat noteworthy because

of its occurrence at such a low elevation.

It is a surprise to find anywhere in Central America an unde-

scribed Tabebuia, and especially so distinct a one as this. The

combination of trifoliolate entire glabrous leaves and showy yellow

flowers makes the plant quite unlike any of the other species known

from the region, and it seems altogether superfluous to compare it

in detail with any of them.

It is certainly not desirable to add to the already too large

number of species ascribed to the genera Ladenbergia and Cinchona,

most of them forms which can be distinguished with difficulty if at

all. It is, however, impossible to refer this Venezuelan tree satis-

factorily to any species hitherto described in Ladenbergia. It is

clearly related to L. magnifolia (R. & P.) Klotzsch, but in that the

corollas are only half as large as in L. Pittieri, and the corolla lobes

are of approximately the same length as the tube.

I feel confident that this plant does not belong to the genus

Deppea, a group unknown heretofore south of Panama, but the

form of the fruit and seeds and the axillary inflorescence seem to

indicate its relationship to this genus. It has been impossible to

discover a more satisfactory place for it, but it is probable that

the flowers, when available, will show that the plant represents a

new generic type.

According to Birschel, the leaves are sometimes 30-45 cm. long.

Pittier gives the vernacular name as "lengua de vaca," doubtless an

allusion to the shape of the leaves. From C. cymosa Jacq. the

present species differs in the much larger capsules and densely

glomerate flowers, and in not having tufts of hairs beneath in the

axils of the leaves.

The species is easily distinguished from others occurring in

Venezuela and Colombia by the dense congested inflorescence.

The leaves of the specimens cited exhibit unusual variation in size

and in amount of pubescence.

The plant here described is represented by an ample amount

of material in good condition, showing an abundance of both flowers

and fruits. Its proper allocation has offered great difficulty, but

detailed study shows that it must be an abnormal member of the

Rubiaceae. It does not fit well in any tribe of the family, but the

structure of the fruit and corolla makes necessary its reference to

the Guettardeae, although even there it is anomalous. To the

Guettardeae belongs another anomalous genus, Machaonia, to

which the present plant has some general resemblance, as to form

of leaves and inflorescence.

It is useless to compare Neoblakea with Machaonia or other

genera of the Guettardeae, because it is not closely related to any

of them. Particularly noteworthy is the form of the stipules, and

the curious small glands present at the base of the bracteoles. The

latter structure does not exist in any other group of the family with

which I am familiar.

The fruit is remarkable for the fact that it is about one-half

superior, but a similar condition is found in certain other genera

of Rubiaceae, notably Houstonia. The fruit appears to be dry, and

probably it is normally 4-celled, but the number of cells varies as

it does in the genus Guettarda. When cross-sectioned there is seen

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

very plainly the stone, with its 4 thin winglike angles, the spaces

within and outside which are filled with a somewhat woody, compact

tissue which may be sectioned rather easily with a sharp razor blade.

This well-marked new genus of the family Rubiaceae is named

for Dr. S. F. Blake, of the United States Department of Agriculture,

as a token of personal esteem and in recognition of the great amount

of attention which he has devoted to the study of Venezuelan

plants.

The relationship of this Mexican tree is evidently with the

monotypic Cuban genus, Phyllomelia, a group known only from

scant material. In Phyllomelia all the calyx lobes are more or less

accrescent, none of them being petiolate; the stipules are persistent,

and the anthers obovate. The proper position of both these genera

within the family Rubiaceae is still uncertain. They seem to be

sharply differentiated from all other American genera, and they

form a group which perhaps should be recognized as a distinct tribe.

Apparently conspecific is a specimen in the United States National

Herbarium from El Talabasal, Michoacan or Guerrero, at 200 m.,

Langlasse 404, collected in October, 1898.

This plant is a remarkable one in several respects. The flowering

and fruiting specimens are so different in aspect that at first I did

not associate them. In the flowering specimens the calyx lobes are

very small, and there is nothing to indicate that one will develop

into a large ovate limb. A few sterile flowers present on the fruiting

specimens are exactly like the young calyces, else I should hesitate

to join the two Yucatan collections.

The tree must be a very showy and handsome one, like Calyco-

phyllum, which the fruiting specimens much resemble in general

appearance. Its occurrence in two regions so distant as Yucatan

and Michoacan is remarkable, and it is strange that so conspicuous

a tree has not been collected more frequently, and described long ago.

The type sheet in the Kew herbarium bears this unpublished

Matthiola frondosa, based upon Moritz's name, but the latter seems

not to have been published, and I find no reference to it anywhere.

Among the Venezuelan species this plant is easily recognized by the

strictly bifurcate inflorescence. The only species similar is G.

discolor Rusby, but the pubescence of that is altogether different.

From Mexico there are known only two other species of this

genus, Palicourea Galeottiana Mart, and P. nigrescens Mart. & Gal.

The description of the latter species suggests its relationship with

the present plant, but the stipule lobes of P. nigrescens are said to

be linear-lanceolate, and the inflorescence subsessile and much

shorter than the leaves.
