The United States National Herbarium, which was founded by the
Smithsonian Institution, was transferred in the year 1868 to the
Department of Agriculture and continued to be maintained by that
department until July 1, 1896, when it was returned to the official
custody of the Smithsonian Institution. The Department of Agri-
culture, however, continued to publish the series of botanical reports
entitled “Contributions from the United States National Herbarium,”
which it had begun in the year 1890, until, on July 1, 1902, the Na-
tional Museum, in pursuance of an act of Congress, assumed respon-
sibility for the publication. The first seven volumes of the series
where issued by the Department of Agriculture.

PREFACE
Tux present paper, by E. C. Leonard, associate curator of the De-
partment of Botany, U. S. National Museum, is the first of three parts
of a critical account of the Acanthaceae of Colombia. Mr. Leonard
has studied this family over a period of many years and has prepared
various systematic and regional revisions. The family is divided into
four subfamilies, of which the first three are treated in their entirety
in this first part ; of the fourth and largest subfamily, 5 of its 18 tribes
are covered in the present paper. The Acanthaceae include many
showy and beautiful plants, which are or should be in cultivation; the
family is cosmopolitan in the tropical and subtropical parts of the
world and is especially well developed in Andean America. In
Colombia the family demonstrates a high percentage of specific
endemism. Fourteen genera, including 72 species, of which 30 are
described as new, are discussed in the present treatment.

THE ACANTHACEAE OF COLOMBIA, I
By Emery C. LEONARD
INTRODUCTION
Prior to this present revision no attempt has been made to bring
together taxonomic considerations of all the Colombian Acanthaceae.
In DeCandolle’s Prodromus (vol. 11, 1847), Nees published the then
known Colombian species. Subsequently, a number of isolated ones
were described by Lindau and other botanists, but no general work
containing keys has yet been attempted. This present paper is by no
means the final word, for almost any fair-sized new collection will still
produce undescribed material, especially in the genera Af endoncia,
Ruellia, Aphelandra, and Dicliptera. The specimens studied so far
seem to indicate that botanical exploration is still needed in eastern
Colombia. The new Putumayo material, for example, has furnished
abundant novelties. What further or extensive collections will reveal
from Amazonas, Vaupés, Arauca, eastern Caqueta, Meta, and Boyaca
can be left only to conjecture.
The purpose of this paper is to discuss, in an orderly fashion, all
the known Colombian species of the family as a ready reference for
botanists, so that they may identify their collections of acanthaceous
plants or use the keys for detecting further undescribed species. Ex-
cept for brief discussions to indicate the possible relationship of
novelties to allied species, no attempt has been made in this paper to
consider the phylogeny of the family. A thorough treatment of this
subject is required in monographiec works but is extraneous in a re-
vision. For the same reason detailed morphological discussions, except
for the formal descriptions, will also be omitted. Full synonomy has
not been attempted. Only the name-bringing synonyms or those based
wholly or partly on Colombian species, as a rule, have been included.
In tropical and subtropical regions, the family as a whole is cosmo-
politan, although a number of genera are confined to one hemisphere
only. Strange as it may seem, with the exception of a few species of
Acanthus in the Mediterranean region, no Acanthaceae are to be found
in Europe, even though Africa abounds in them. The following list
will show in a general way the distribution of the genera treated in
Part I of my revision :

2 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM
Staurogyne: Both hemispheres.
Elytraria: Tropical America.
Nelsonia: Both hemispheres.
Mendoncia: Tropical America.
Thunbergia: Old World, but mostly African.
Bravaisia: Tropical America.
Trichanthera: Tropical America.
Sanchezia: Tropical America.
Hygrophila: Both hemispheres.
Blechum: Both hemispheres.
Phaylopsis: Eastern hemisphere. An escape in America.
Ruellia: Both hemispheres,
Barleria: Both hemispheres.
Teliostachya: Tropical America and west Africa.
In view of the mountainous nature of Colombia, endemism is to be
expected; many of the new species treated here are based on a single
collection, and the range of others is limited to a single department
or to a few adjacent ones. Colombian species seldom occur in Peru.
There is, nevertheless, some affinity along the eastern border to the
plants of northwestern Brazil and western Venezuela. But, again,
there is scarcely any affinity to the Panamanian flora except in the
case of a few species that follow the mountain ranges of Panama down
through El Chocé.
This large and complex group of plants has been placed by Engler,
in his System,’ between the small families Globulariaceae and Plan-
taginaceae, but it is near the larger and more complex family Ges-
neriaceae. Because of a superficial resemblance, confusion sometimes
arises in distinguishing these two families. Certain characteristics
are almost always present, however, by which an acanthaceous plant
can be recognized. The most prominent and easiest to detect of these
characters is the presence of cystoliths, small mineral concretions ap-
pearing as minute short lines on the upper surface of the leaf blades,
the upper portions of the stems, on the branches of the inflorescence,
and on the calyx. Similar cystoliths do occur in a few other distant
families such as Urticaceae. In Acanthaceae they are lacking only
on the members of the first three (relatively small) subfamilies (Nel-
sonioideae, Mendoncioideae, and Thunbergioideae), and for some un-
accountable reason in the large genus Aphelandra of the fourth sub-
family (Acanthoideae). In Mendoncioideae raised stelliform mark-
ings at the bases of the hairs on the upper surface of the leaf blades
may appear to be of the nature of cystoliths. Bremekamp,? however,
contends that they are merely large raised epidermal cells so elevated
by differential shrinkage. A more general earmark of the family, and

peculiar to it, is the unusual subulate hook-shaped extension of the
funicle (retinacula), which supports the seed. This character is again
lacking in the fruit of the first three subfamilies. Superficially there
are actually few traits that associate these subfamilies with typical
Acanthaceae.
Probably the best-known acanthaceous plants in cultivation belong
to the genus Acanthus (axavOos, thorny plant). This name was also
given to bear’s-breech or Acanthus mollis. A conventionalized form
of the leaf of A. mollés may have been the one used so extensively in
Roman architecture. That ornamenting Corinthian columns was sup-
posed to have been derived from A. spinosus Li.
Some of the plants of the family are reported to have medicinal
qualities but are not included in the standard works of materia medica.
Many others have beautiful and conspicuous flowers, especially in the
genera Sanchezia, Ruellia, and Aphelandra, but most of these are dif-
ficult to grow, thrive only in greenhouses, and even there require espe-
cial care. Jacobinia magnifica Benth. & Hook., Aphelandra auran-
tiaca Lindl. or some of its forms, and Sanchezia speciosa Leonard are
perhaps the species most often met with in greenhouses. Recently
Beloperone guttata Brandeg., from Mexico, has become popular as a
pot plant. In tropical regions a number of species of Thunbergia are
encouraged as garden plants.
The sequence of subfamilies and tribes is that of Dalla Torre and
Harms’ Genera Siphonogamarum.
The specimens cited are chiefly those deposited in the U. S. National
Herbarium. > _.... Wg

INTRODUCTION
Ten tribes are listed by Dalla Torre and Harms (Genera Siphono-
gamarum) in the series Imbricatae. Eight of these tribes are repre-
sented by one or more genera from Colombia. The following five
tribes are discussed in the present treatment:
6. Aphelandreae
7. Rhombochlamydeae
8. Asystasieae
9. Graptophylleae
10. Pseuderanthemeae
The remaining. three tribes, Odontonemeae, Isoglosseae, and Justi-
cieae, will be reserved for treatment in Part III of the Acanthaceae
of Colombia.

15. NERIACANTHUS Benth.
Neriacanthus Benth., in Benth. & Hook. Gen. Pl. 2: 1096. 1876. This is one of
the many generic names in the family Acanthaceae formed by adding a
prefix to Acanthus. Here the prefix Neri, from vnpés, means wet, in allusion,
undoubtedly, to the high damp mountain slopes, the natural habitat of the
species. Type species: Neriacanthus purdieanus Benth. Type locality:
Jamaica.
Aphanandrium Lindau; Engl. & Prantl, Planzenfam. IV, 3b: 328. 1895. The
hame is derived from agav#s, invisible, and avépés male sex, in allusion,
no doubt, to the deeply included stamens. Type species: Aphanandrium
lehmannianum,
Plants shrubby; leaves opposite, the blades entire or undulate ;
flowers borne in terminal or axillary peduncled spikes; bracts im-
bricate, entire, usually colored, conspicuous; bractlets shorter than the
calyx; calyx deeply 5-parted, the segments narrow, the posterior one
slightly wider than the others, all striate-nerved, their margins
subhyaline; corolla tube subcylindric, the lobes imbricate, the posterior

lobe borne innermost and slightly larger than the others, the anterior
pair borne outermost; fertile stamens 4, included; staminode filiform ;
anthers narrow, 1-celled, terminated by a slender tip; capsules short-
stipitate, glabrous, nitid, finely punctate, 4-seeded, the basal portion
solid; seeds flattened, suborbicular, subtended by blunt-tipped reti-
nacula.
Previous to the present paper only two species have been proposed
in this genus, V. lehmannianus, from Colombia and Pert, and ¥.
purdieanus Benth. from Jamaica. The genus is easily recognized by
its white, whitish or pinkish bracts, slender-tubed corollas, and 1-celled
anthers.

Neriacanthus grandiflorus is a well-marked species definitely dis-
tinct from V. lehmannianus and easily separated from it by its large
lilac flowers and by the nearly glabrous leaf blades. In V. lehman-
LEONARD: THE ACANTHACEAE OF COLOMBIA, II 123
néianus the flowers are white and do not exceed 2 cm. in length and
the leaf blades are generally puberulous. Likewise the bracts of this
new species are much larger than those of WV. lehmannianus. At least
some of them are as much as 23 mm. long, instead of only 15 mm.

16. STENANDRIUM Nees
Stenandrium Nees, in Lindl. Intr. Bot., ed. 2, 444, 1886. The name comes from
orevés, Darrow, and avydpés, male sex, and alludes to the narrow anthers, a
character common to the tribe Aphelandreae. Type species: Stenandrium
mandioccanum Nees.
Small perennial, caulescent or acaulescent herbs, the leaves often
radical; flowers borne in spikes, these sessile, subsessile, pedunculate
or borne on slender scapes, the peduncles or scapes simple or branched;
bracts ovate to lanceolate, herbaceous, entire or occasionally toothed ;
calyx segments 5, narrow, subequal, usually striate-nerved; corollas
pink, white or purple, the tube slender, cylindric, more or less incurved
and briefly ampliate at throat, the limb oblique, spreading, 5-lobed,
the lobes obovate, rounded or retuse, imbricate ; Stamens 4, didynamous,
affixed in the throat of the corolla tube, included, the filaments very
short, the anthers oblong, 1-celled, conniving or subcohering in pairs,
sometimes barbellate at tip, muticous at base; style subclavate at apex,
briefly 2-lobed ; ovules 2 in each cavity ; capsules oblong to subfusiform,
subterete ; seeds 4 or fewer by abortion, plano-compressed, orbiculate,
minutely hispid or muricate, subtended by rather long retinacula.
The species of this genus are widely distributed throughout the
tropical and subtropical regions of America. The acaulescent ones
are easy enough to recognize by virtue of their habit alone; the
stemmed plants may confuse one at first sight by their very different
appearance, but they always possess the characteristic flowers of the
genus. More than 60 species are now recognized.

Stenandrium corymbosum Nees, DC. Prodr. 11: 727. 1847. Type collected in
Colombia by Lobb (No. 171) (Hooker Herbarium, Kew). Corymbosum
alludes to the flat-topped inflorescence, this contrasting with the usually
peduncled spikes of the genus.

glabrous; leaf blades oblong, 10 to 12 cm. long, 2 to 2.5 cm. wide,
obtusish and long-cuspidate at apex, acute at base, entire; petioles up
to 18 mm. long; flowers borne in short spikes, these in turn borne in a
spreading, 3-parted corymb; bracts oval, much longer than the calyx,
obtuse, membranaceous, sessile, spreading; bractlets shorter than the
calyx; corolla about 13 mm. long.

2. Stenandrium radicosum Nees
Stenandrium radicosum Nees, DC. Prodr. 11: 283. 1847. Type locality :
“Prope S. Martha et Maracaybo in Colombia in silvis montanis humidis
(h. Hooker), Moritz n. 1273 in h. gen. berol.” A photograph of the type
material from the Berlin Herbarium is in the U. §. National Herbarium
(Field Mus. photograph No. 8686). Radicosum alludes to the numerous
roots supposedly produced by the plant.
Stems rooting at base, leafy toward tip; leaf blades elliptic-oblong,
up to 16 cm. long and 6 cm. wide, acutish at apex, narrowed at base
and decurrent on the petiole; petioles slender, up to 4 cm. long;
peduncles up to 8 cm. long, simple or forked; spikes lax, up to 5 cm.
long, the bracts lanceolate, spreading, acuminate, bearing a pair of
small marginal teeth near the apex, ciliate.
Specimen not seen. Description compiled from the original and
the dimensions computed from the photograph.
The type locality as given by Nees is confusing. As Moritz is not
known to have collected in Colombia his No. 1273 most likely came
from the Venezuela side in the general vicinity of Maracaibo, Zulia.
Since the species however may actually occur in the adjacent Santa
Marta Mountains of Colombia, it has been included in the present
treatment.

Ruellia dulcis Cav. Icon. Pl. 6: 62. pl. 585, fig. 2, 1801. Type collected near
Taleahuano, Chile, by Cavanilles. Dulcis, sweet, alludes, no doubt, to the
esthetic appeal of the plant. This specific name was evidently suggested
to Cavanilles by its vernacular name “canchelahua dulce.”

Aphelandra R. Br. Prodr, Fl. Nov. Holl. 475. 1810. Here under Justicia Robert
Brown proposed the generic name Aphelandra to include the following
species: Justicia puleherrima Jacq., J. scabra Vahl, and J. cristata Jacq.
Type species: Justicia pulcherrima Jacq. Aphelandra is from the Greek
dgeAqs, smooth, and apvSpés, anther.
Hemisandra Scheidw. Bull. Acad. Sci. Bruxelles. 9: 22. 1842. Type species: H.

Lagochilium Nees, in Mart. Fl. Bras. 9: 83. pl. 10. 1847. Six species are described
here by Nees. The first of these, L. mazrimilianum Nees, by virtue of its
being illustrated, can be chosen as the type species. When compared with
Aphelundra, the genus Lagochilium is characterized, according to Nees, by its
nearly regular (subbilabiate) corolla limb and generally by its herbaceous
nature. It seems in a way to be intermediate between Aphelandra and
Stenandrium. The epithet is derived from the Greek words, Aayws, hare, and
xetdos, lip, evidently from a fancied resemblance of one of the corolla lobes
to a hare’s lip.

flowers of various shades of red, yellow, orange or occasionally white
or cream, borne in terminal usually large-bracted spikes; flower-
bracts entire or toothed, those of certain species bearing dorsally on
either side a group of ocelli, these few, oval, brownish, rather con-
spicuous or very numerous and minute appearing even under magni-
fication as a more or less irregular alveolar area; bractlets various, in a
few species rudimentary; calyx divided nearly to the base into 5
segments, these usually lanceolate or oblong-lanceolate, coriaceous or
chartaceous, striate-veined, the posterior segment usually broader
than the others and sometimes toothed at tip (in a few species the
calyx is rudimentary) ; corolla tube straight or curved, the limb usually
bilabiate, the upper lip erect, bilobed or entire, the lower lip reflexed-
spreading, 3-lobed, the middle lobe often larger than the lateral ones,
these sometimes very small and adnate to the base of the upper lip;
stamens 4, usually slightly exserted, but rarely if ever exceeding the
upper lip of the corolla; anthers narrow, one-celled, often pilose
dorsally and adhering at tips by webby hairs; capsules usually ovoid
or cylindric, 4-seeded.
A phelandra, one of the larger genera of the family, is restricted to
tropical America. The flowering spikes are often large and beauti-
fully colored, even to the bracts, and in certain species varigated or
colored leaves occur. In spite of its attractiveness, however, these
plants are rarely met with in cultivation, possibly because of culture
difficulties. This may be explained by the fact that many of the
species are shade plants from damp forests. In contrast to most
genera of the family, there are no cystoliths.
Important characters in the genus A phelandra, linking large series
of species, are the presence of spiny interpetiolar bracts, the presence
or absence of teeth, spiny or otherwise, on the margins of the leaf
blades or flower bracts, and the presence or absence of ocelli on the
flower bracts. These ocelli may be represented by one to several
rather large oval brownish or blackish glands plainly visible under
a lens or even to the unaided eye, or again they may be very numerous
and minute, visible only under a high magnification. Without aid of
a lens, these minute ocelli appear as more or less irregular dark alveo-
lar areas on the bracts.
In one large group of species, chiefly the pulcherrima-tetragona
complex, the lower lip of the corolla is apparently entire and seems
to consist of a single segment. . Pseuderanthemum idroboi Leonard, sp. nov. Figure 108

1902. Type grown in the Establishment for New and Rare Plants, King’s
Road, Chelsea, London, 8S. W., by William Bull. Although publishing the
species in an advertisement, Mr. Bull gives an adequate description and,
inasmuch as the Gardener’s Chronicle is a periodical well known to botanists
and available in most botanical libraries, Dr. L. H. Bailey agrees that
Franthemum atrovurpureum is a legitimate name. (Gentes Herb. 4: 351.

The native country of Pseuderanthemum atropurpureum is not
definitely known, but was probably somewhere in Polynesia. It is
found frequently in tropical America, either under cultivation or as
an escape. Pickel (No. 2361, Brazil) states on his label that the
capsules are purple.

Type in the Herbario Nacional Colombiano, collected in a wet forest
along the Rio Putumayo at Puerto Porvenir, Comisarfa of Putumayo,
Colombia, 230 to 250 meters altitude, November 17, 1940, by J. Cuatre-
casas (No. 10629). Fragment of type in the U. S. National Herbar-
ium, No. 1995427.
Cuatrecasas’ No. 11086, collected in wet forests of Quebrada de la
Hormiga, Rio San Miguel, Putamayo, 290 meters altitude, December
16, 1940, is also of this species (Col).
The leaf blades of Pseuderanthemum potamophilum are large for the
genus and, under a lens, the cystoliths are noticeably numerous and
conspicuous on both surfaces of the blades. The species is further
marked by the dense, crowded sessile or short-pedunculate fascicles of
white or whitish flowers, these forming a narrow, spikelike raceme.
The specific epithet is derived from orayés, river, and ¢udéw, to love.

Such characters as its slender, simple or forked racemes and its
lanceolate, slenderly acuminate, chartaceous leaf blades serve to iden-
tify Pseuderanthemum hylophilum. Only immature corollas are pres-
ent on the type material; the color of these is not apparent. The
specific epithet is derived from Xn, forest, and ¢:déw, to love.

Chapon in the western part of the Department of Boyacé, Colombia,
“3,000 ft.” altitude, September 19, 1982, by A. E. Lawrance (No.

Pseuderanthemum chaponense can be easily recognized by the slen-
der, densely glandular-papillose corolla tube, and narrow corolla
lobes.

Type in the herbarium of the New York Botanical Garden, collected
on the bank of a stream in dense forest in El Umbo region, western
part of the Department of Boyaca, Colombia, “2,500 ft.” altitude,
October 1, 1982, by A. E. Lawrance (No. 501).
The type specimen of Pseuderanthemum chaponense f. lilacinum
was collected from a plant “2-4 ft.” high with stems up to “14 inch”
in diameter. Mr. Lawrance states that it was “beautiful in the forest
and similar to lilac.” The label on Lawrance 441, the typical white-
flowered form, states that the plant was 15-20 feet high, with stems
up to an inch in diameter. These data are probably erroneous. The
specimen indicates that the plant is subherbaceous, slender-stemmed,
and probably only a meter high or less.

Publications of the United States National Herbarium
The United States National Herbarium, which was founded by the
Smithsonian Institution, was transferred in the year 1868 to the
Department of Agriculture and continued to be maintained by that
department until July 1, 1896, when it was returned to the official
custody of the Smithsonian Institution. The Department of Agri-
culture, however, continued to publish the series of botanical reports
entitled “Contributions from the United States National Herbarium,”
which it had begun in the year 1890, until, on July 1, 1902, the Na-
tional Museum, in pursuance of an act of Congress, assumed respon-
sibility for the publication. The first seven volumes of the series
where issued by the Department of Agriculture.

Cundinamarca, Colombia, 2,250 to 2,300 meters altitude, October 2,
1938, by J. Cuatrecasas (No. 214).
The flowers of Dicliptera sciaphila are large for the genus. The
strongly ciliate bracts and dull lead-colored puberulous calyx (dried
material) furnish further diagnostic characters. The specific epit het
“sciaphila” (cxd, shade, and ¢iXos, loving) alludes to a preference to
dense forests.

Type in the U. S. National Herbarium, No. 1900475, collected
at Quebrada de los Osos, valley of the Rio Bugalagrande, Department
of HI Valle, Colombia, 2,170 meters altitude, April 20, 1946, by J.
Cuatrecasas (No. 20947). Isotype: US.
A specimen collected in thickets at Rioblanco, vicinity of Popaydn,
Department of Cauca, Colombia, 1,800 meters altitude, July 9, 1939,
by Pérez-Arbeliez and Cuatrecasas, No. 5788 (US), is also of this
species.
The color of the corolla is not apparent in the dried material.
Only immature flowers were present and, judging from the complete-
ness of the specimens in other respects, this absence of expanded
corollas may have been due to cleistogamy. The specific epithet is
derived from Sdptos, thicket, and ¢ios, loving.

Type in the U. S. National Herbarium, No. 1799084, collected in
dry thickets on the left slope of the valley of the Rio Chicamocha,
between Soatd and Tipacoque, Department of Boyac&é, Colombia,
1,700 to 2,000 meters altitude, July 18, 1940, by J. Cuatrecasas and
H. Garcfa-Barriga (No. 9820).
The main stem leaves, deciduous and lacking on the type specimen,
may prove to be somewhat larger than those subtending the verti-
cillasters. The stem is woody at base and the plant probably affects
a sprawling habit. The exact height of the plant cannot be approx-
imated from the type material, probably a basal portion. The
branches are about 20 cm. long, but the main stem may reach 1 meter
or more.

Type in the U. 8S. National Herbarium, No. 1852703, collected in
forest at La Laguna, on the left side of the valley of the Rio San-
juniquin, Department of El Valle, Colombia, 1,250 to 1,400 meters
altitude, December 10-20, 1943, by J. Cuatrecasas (No. 15468).
Dicliptera sarcochroma is very closely realted to D. cuatrecasasii,
resembling it in many respects. Both are lush growers, have large
thin and nearly glabrous leaf blades, thick subglabrous stems and
similar bracts. In D. sarcochroma, however, the long marginal hairs
of the larger bracts subtending the cymules are entirely lacking.
The inflorescence of D. cuatrecasasii is much more crowded than that
of D. sarcochroma, forming dense terminal spikelike thyrsi. The
epithet sarcochroma (cdpé, flesh, and xpaya, color) alludes to the color
of the corollas.

The specific epithet alludes to the shovel-shaped cymule bracts.
Dieliptera batilliformis is closely related to D. megalochlamys differing
chiefly from that species in its rounded ovate cymule bracts definitely
longer than broad, and the short-stalked simple or forked cymes.
The cymule bracts of D. megalochlamys are broader than long and
cymes 3-parted instead of forked, the subtending bracts of the node
larger, and the basal segment of the peduncle considerably longer.

Diclhiptera columbiana is related to D. megalochlamys and resembles
it in many ways; however, D. columbiana can be recognized by its much
shorter peduncles, and smaller stature, cymule bracts, and leaf blades.

Dicliptera compacta can be distinguished from D. columbiana,
possibly its closest relative, by the crowded inflorescences and the
relatively longer leaf blades. The specific epithet alludes to the
crowded cymes.

26. ODONTONEMA Nees
Odontonema Nees in Linnaea 16: 300. 1842. The epithet is derived from the
Greek words ééovr0-, tooth, and vaya, thread, referring to toothed filaments.
Type species: Odontonema lucidum Nees (Justicia lucida Andr.). Type
locality: “in Insula Barbados.”’
Thyrsacanthus Nees in Mart. Fl Bras 9: 97, pl 13. 1847. The epithet is derived
from 6@tpcos, thyrse, and &xavOos, acanthus. Type species.: Thyrsacanthus
barlerioides Nees.
Herbs or shrubs; leaves often rather large, opposite, entire or
undulate; flowers borne in narrow terminal panicles or racemes;
calyx 5-parted, the segments subulate; corollas white, red, or yellow,
the tube relatively slender, the throat only slightly enlarged, the
limb 2-lipped, the lips subequal, the upper lip 2-lobed, the lower
3-lobed, the lobes usually rounded; stamens 2, the anther lobes
parallel, narrow, blunt at base; staminodes 2; capsules clavate, the
solid basal portion slender; seeds 4.
The genus consists of 40 species or more, limited to tropical regions
of the Western Hemisphere. QOdontonema strictum (Nees) Kuntze
(also known as Justicia coccinea) is often found in cultivation. It is
frequently difficult to distinguish between Odontonema and Pseude-
ranthemum, especially if the specimens offer only immature flowers.
The flowers of both genera possess two stamens and two staminodes.
The corollas of Pseuderanthemum, however, are usually smaller with
very small regular lobes, the tube very narrow, and the stamens
included. Those of Odontonema are larger, often several centimeters
long, the limb definitely 2-lipped, the lobes rather large and the
stamens exserted or at least reaching the mouth of the corolla tube.

Odontonema coccineum is a well-marked species easily recognized
by its tall slender habit, by its large glabrous firm leaf blades narrowed
to a small rounded base and supported by a short stout petiole, and by
its rather large and compact panicle of brilliant showy crimson
flowers. The leaf blades resemble those of Odontonema amplexicaule
(Nees) Kuntze of Brazil, but that species has a racemose inflorescence
and pubescent stems.

396 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM
The similarity of the leaf blades and inflorescence of Odontonema
ampelocaule and O. schomburgkianum (Nees) Kuntze of British
Guiana suggests a relationship between the two species. 0. schom-
burgkianum, however, is a shrub only about 1 meter high and has
a glandular inflorescence and larger flowers (up to 4 cm. long).
The type material consists of a section of stem about 45 em. long
bearing toward the lower end two short branches, one of which is
terminated by the raceme. Both branches are noticeably reflexed.
Garcia-Barriga states in his label notes that the stems are quite thick
(“tallos gruesos”), so the entire plant must reach a considerable
height. Its scandent nature suggests its specific epithet which is
from the Greek, dyedos, vine, and xavdés, stem.

tragonal, rather sparingly hirtellous, the hairs spreading or ascending,
up to about 0.5 mm. long, more or less curved and disposed in two
lines, the lower portions subterete, light gray, subnitid; leaf blades
lanceolate to elliptic, up to 10 cm. long and 5.2 cm. wide, short-
acuminate, narrowed at base, moderately firm, entire or undulate,

wide, the others successively smaller toward tip of spike, all acuminate,
glabrous or sparingly hirsute; bractlets similar to the bracts but much
smaller; pedicels slender, ca. 4 mm. long, hirtellous, the hairs 125y
long; calyx 5 mm. long, the segments narrowly triangular, 4 to 4.5 mm.

broad; staminodes 4 to 5 mm. long, glabrous; ovary glabrous; style
about 2 cm. long, glabrous, the stigma linear, but slightly broader
than the style; capsules not seen.
The largish red flowers more or less secund in terminal loose racemes
suggest, as Nees points out in his description of Thyrsacanthus ruber,
the species Odontonema schomburgkianum from British Guiana. The
above description was drawn from Smith’s No. 1390, a plant which
differs in several respects from Rohr’s type. The leaf blades of
Smith’s specimen are broadly lanceolate or elliptic (5.2 cm. wide)
instead of narrowly lanceolate (2 cm. wide) as in Rohr’s collection,
and the racemes are hirtellous instead of glabrous. The large red
corollas, however, with their short lips divided into obtuse suborbi-
cular lobes, typical of both Rohr’s and Smith’s specimens, leads one
to include them in the same species. O. bracteolatum also varies
in the relative width of the leaf blades and in the amount of pubescence
on stems and inflorescences.
The following notes accompany H. H. Smith’s sheet in the New
York Botanical Garden: “Shrub, 2-4 ft. with few branches, and often
drooping or procumbent; air roots are frequent. Flower scarlet.
Locally common in damp mountain forest about 5000 ft. The
specimens were collected above Las Nubes, Dec. 17.”

loose to dense panicles usually 10 to 20 cm. long and 1 to 5 cm. broad,
the lateral branches of loose panicles usually basal, solitary or in pairs,
up to 2 cm. long, several-flowered, the upper portion of the panicle

Odontonema bracteolatum varies greatly in the relative width of
leaf blades, the amount of pubescence of the rachis and upper portion
of the stems, and in the amount of branching of the panicle. The
leaf blades of Dugand & Garcia-Barriga’s No. 2493 do not exceed
21 mm. in width whereas in Allen’s No. 866 they are as much as 4.5
cm. wide. Smith’s Bonda specimen possesses a densely hirsute stem
and rachis but a slender, lax, almost racemose inflorescence, only the
lowermost flowers borne on sparingly branched peduncles. At the
other extreme, Haught’s No. 3946 has a rachis and upper stem portion
almost glabrous and a compact crowded panicle, its lateral branches
produced several in a cluster from the base to the tip of the inflores-
cence. Variation between these extremes are exhibited by the other
specimens cited.
The species is usually found growing along shaded streams in
forests at 70 to 800 meters altitude. It produces showy panicles of
bright red corollas and blooms more or less throughout the year.

Odontonema bracteolatum var. parviflorum differs in no way from
the typical form except in the size of the corolla, this being 15 to 17
mm. long instead of 25 to 35 mm. long. The leaf blades of the
specimens examined are predominantly narrow, not exceeding 3 cm.
in width. However, narrow-leafed plants of the typical form with
large corollas are common.
Nees’ Thyrsacanthus bracteolatus is based on Jacquin’s plant and
Linden’s No. 703. Linden’s collection, as can be readily seen from
the photograph (No. 32706), is of the small-flowered form.

Fittonia verschaffeltii E. Coem., Fl. des Serres 15: 186.1865. Based on Gymno-
stachyum verschaffeltia Lem.
Repent or ascending herb up to 30 cm. long; stems pilose to sub-
tomentose; leaf blades ovate to elliptic, up to 10 cm. long and 7 cm.
wide, rounded or obtuse at tip, cordate at base, the upper surface
dull green, the costa and conspicuously reticulated veins purple;
spikes up to 8 cm. long and 1.5 cm. wide; peduncles up to 12 cm. long,
pilose or subtomentose, the hairs disposed more or less in two rows;
bracts oval, up to 13 mm. long and 8 mm. wide; corolla white or yellow.
Herbarium specimens of Fittonia argyroneura and F. verschaffeltu
are very similar and dried specimens are extremely difficult to separate,
especially since the purple coloring of the veins invariably fades.
The habit of growth, pubescence, inflorescence, and corollas of
the two species are practically identical. The upper surface of the
leaf blades of F’. verschaffeltti has been described as duller, the epi-
dermis composed of more densely placed conical cells so as to present
a velvety appearance in fresh plants. In contrast, the leaves of /.
argyroneura are smoother and of a nitid green color. This contrast,
strong as it may be in live plants, is weak indeed if herbarium material
is studied and unless there yet remains a slight trace of the purple
coloration in the veins, or the specimen is accompanied by proper
field notes, it is practically impossible to decide to which of the two
species any given specimen might belong.
In the Putumayo region, according to Schultes, the plant is called
“Mee-ni-ku-ru” by the Kofén natives and is used medicinally. The
two species treated here, as well as the suffrutescent /. gigantea Linden
of Pert, are found in cultivation.

30. KALBREYERIELLA Lindau
Kalbreyeriella Lindau, Notizbl. Berlin 8: 143. 1922. Named in honor of W.
Kalbreyer, the collector of the type species, K. rostellata Lindau. Type
species: Kalbreyeriella rostellata Lindau. Type locality: Near Plateado,
Antioquia, Colombia.
Herbs or shrubs; leaves petioled, usually ovate or oblong-lanceolate ;
flowers borne in spikes, racemes or narrow panicles, these spicate or
racemose toward tip; bracts and bractlets shorter than the calyx;
calyx deeply segmented, the segments 5, lanceolate, thin, slenderly
acute; corolla broadly tubular, slightly ventricose, scarlet, glabrous or
hirtellous, rostrate at tip before the expansion of the lips, the upper
lip in expanded flowers erect, narrow, embracing the stamens and
pistil, the lower lip triangular, recurved, minutely trilobate at tip;
stamens 2, exserted; anthers 1-celled (one of them 2-celled in K.
cabrerae) ; ovary glabrous; mature capsules not seen.
The genus Kalbreyeriella is closely related to Razisea, differing
mainly in its rostrate corollas (before expansion). Lindau described
K. rostellata as having a 4-parted calyx, but I have found only 5-
parted ones in the many specimens that I have examined of this
genus, including the isotype material in the Kew Herbarium of
Lindau’s species.

leaves and the yellow flowers.
2. Kalbreyeriella rostellata Lindau
Ka'breyeriella rostellata Lindau, Notizbl. 8: 143. 1922. Type collected in
shady woods near Plateado, Department of Antioquia, Colombia, 2,300
meters altitude, March 31, 1880, by W. Kalbreyer (No. 1524).
Suffrutescent plants up to 1 meter high; stems erect or ascending,
simple or sparingly branched, glabrous to moderately hirtellous, the
hairs appressed, ascending or recurved, up to 0.25 mm. long, septate;
leaf blades oblong-lanceolate, oblong or oblanceolate, up to 24 cm.
long and 10 cm. wide but usually about 10 cm. long and 4.5 cm. wide,
short-acuminate, narrowed at base, moderately firm, entire or un-
dulate, the upper surface glabrous to moderately pilose with curved
ascending red-septate hairs up to 1 mm. long, the costa and lateral
veins (9 or 10 pairs) moderately prominent, sometimes red, the lower
surface glabrous or the costa and lateral veins hirtellous, the hairs
about 0.25 mm. long, mostly curved and ascending, the venation
more prominent than above, the cystoliths conspicuous under a lens,
mostly straight or slightly curved, up to 225y long, these often absent
on the upper leaf-surface; petioles usually about 2 cm. long but oc-
casionally reaching 4 cm., glabrous or sparingly hirtellous; flowers
borne in terminal loose peduncled spikes or racemes (spicate toward
tip) up to 20 cm. long, the peduncles up to 2 cm. long, these and the
rachises glabrous or sparingly or even densely hirtellous, the hairs
variously curved, up to 0.25 mm. long, sometimes septate, the lower-
most internodes 10 to 15 mm. long, the others successively shorter
toward tip of inflorescence, the pedicels of the lowermost flowers
slender, up to 4 mm. long, minutely hirtellous in two lines; bracts
lanceolate, the lowermost 5 to 10 mm. long, and 2 to 3 mm. wide, the
others becoming smaller towards tip of inflorescence, all acute, glabrous
to moderately pilose; bractlets similar to the bracts but somewhat
longer; calyx 16 mm. long, 5-parted, deeply segmented, the segments
lanceolate, 10 mm. long, 3 mm. wide at middle, acute, thin, minutely
and sparingly ciliolate, faintly nerved; corollas a bright showy red, up
to 5.5 cm. long, glabrous or sparingly and minutely strigose at tip,
this rostrate and recurved before expanding, the tube about 2.5 mm.
broad at base, enlarged rather abruptly at 5 mm. above base to 12 mm.
at middle, thence reduced to 10 mm. at mouth, the upper lip lanceolate,
acute, 13 mm. long, 4 mm. wide at base, erect in expanded flowers,
the tip straight or recurved, the lower lip triangular, recurved, 14 mm.
wide at base, narrowed to an acute 3-lobed tip, the lobes about 1 mm.
long and 0.5 mm. wide; stamens attached near base of corolla tube,
412 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM
about 5 cm. long, exserted 15 mm. beyond mouth of corolla tube and
slightly exceeding the upper lip which partially enfolds them, the
anthers 5 mm. long and 1 mm. broad at middle, narrowed toward
both ends to bluntish tips, both anthers and filaments glabrous;
disc 1 mm. long, this and the ovary glabrous; style slightly shorter
than the stamens, glabrous; capsules not seen.
There is variation in the amount of pubescence and the size of
the leaf blades. The type material is strictly glabrous except the
very young leaves. In Ariste-Joseph’s No. 1085, the upper surfaces
of the leaf blades are conspicuously covered with red-septate hairs;
other specimens show the same character to a more or less marked
degree. Again, the leaf blades of Ariste-Joseph’s material do not
exceed 9 cm. in length nor 2.8 cm. in width, whereas those of Cuatre-
casas’ No. 15160 are as much as 24 cm. long and 9 em. wide. The type
material possesses leaves intermediate between these two extremes.
The specific epithet alludes to the acutely tipped unexpanded
corollas. The species is endemic in Colombia; it is partial to thick
shady forests, usually of the middle altitudes (900 to 1,600 meters),
although Haught’s No. 4723 was collected as low as 100 meters. Its
dark green leaves and brilliant red flowers make it an especially
beautiful and conspicuous species.

mayo, Colombia, 450 to 500 meters altitude, December 25, 1940,
by J. Cuatrecasas, No. 11271.
When compared with K. rostellata, Kalbreyeriella gigas is easily
recognized by its dense narrow panicle, large crimson calyces and
remarkably large leaf blades. The specific epithet, gigas, is from the
Greek yiyas meaning giant, in allusion to the large size of the plants
of this species.
31. SYRINGIDIUM Lindau
Syringidium Lindau, Notizbl. 8: 142. 1922. Diminutive of odpwé, a little pipe,
apparently in allusion to the nearly tubular corolla. Type species:
S. atropurpureum Lindau (Colombia).
Small herbs; stems subquadrangular; leaves medium-sized, lanceo-
late, hirtellous; flowers borne in terminal hairy raceme-like panicles
exceeding the uppermost leaves; bracts small, lanceolate; calyx
5-lobed, the segments lanceolate; corolla subcylindrical, 4-lobed at
tip, the posterior lobe or lip minutely 2-lobed at tip; stamens 2,
the anthers 1-celled; pollen grains subelliptical, aculeate, 2-pored;
seeds 4.
Lindau places his genus after Porphyrocoma. Its subtubular
corolla and lax inflorescence separate it from Stenostephanus. Both
genera have 4-lobed (indistinctly 2-lipped) corollas and exserted
stamens with 1-celled anthers, but in Stenostephanus the corolla
tube is markedly ventricose and the inflorescence dense and spikelike.
The genus Syringidium is represented by a single species.

Type in the U. S. National Herbarium, No. 2059037, collected on
a steep, densely wooded slope of Quebrada Riocito, on the Hacienda
San Luis, 6 km. northwest of Gramalote and 35 km. west of Cucuta,
Department of Norte de Santander, Colombia, 2,400 meters altitude,
April 8, 1944, by R. F. Fosberg and N. C. Fassett (No. 21733).
Fosberg states in his label data that the Quebrada Riocito is on the
headwaters of Rio Peralonso and that the woods where his specimen
was collected were rather dry, at least during the season of his visit,
and that it was not a typical rain forest. Only one plant was seen.
The salient characters of Habracanthus syscius are the numerous,
axillary, rather small, graceful but rigid panicles with their rather
densely hirte'lous rachises and pale lavender flowers, the slenderly
petioled and tipped leaves, and the tumid, swollen jointed, ascending
stems, glabrous below and minutely strigose toward tip. The specific
epithet is from the Greek word ctcxos, meaning “in deep shade” in
allusion to the habitat of the plant.

Type in the U. S. National Herbarium, No. 1850282, collected in
forest between Alto del Loro and Alto de Santa Inés, Region del
Sarare, Department of Norte de Santander, Colombia, 1,800 to 2,200
meters altitude, October 18 to 21, 1941, by J. Cuatrecasas, R. E.
Schultes, and E. Smith (No. 12419).
Habracanthus trichotus agrees with H. cyaneus Lindau in having
blue flowers but differs in other respects. Contrasting sharply is the
rigid, ovoid, and much denser panicle of H. trichotus. Those of H.
cyaneus are very slender and lax, with only a few branches. Further-
more, the leaves of this new species are considerably larger than
those of H. cyaneus, the corollas are glabrous instead of pilose, and
the rachises densely pilose with spreading septate hairs instead of
inconspicuously pubescent.
The height of the plant cannot be determined from the herbarium
specimen, a lateral branch, but, judging from the thickness of the
small section of main stem (about 5 mm.) represented, it could reason-
ably be as much as a meter. The plant was probably somewhat
clambering in habit. Since the few corollas available are apparently
immature or poorly developed, no complete description can be given.

Colonias, above Queremal, valley of the Rio Digua, Department. of
El Valle, 1,950 to 2,050 meters altitude, March 20, 1947, and J. M.
Duque’s No. 1660 collected at El Recuerdo, valley of the Rfo Cali,
1,600 to 1,800 meters, June 15, 1938.
Habracanthus pycnostachys should be easy to recognize by its narrow
cylindric panicles with recurved, violet-red flowers. The label of the
type bears the following field notes: “Hierba robusta, 1.5 m. Hoja
verde haz, verde envés. Bracteas verdes. Raquis, pedinculo y
cAliz purptreo violiceo oscuro. Corola violeta rojiza oscuro. Fila-
mentos y estilo id.””. The label on Duque’s sheet bears the following
data: ‘“Arbusto de 1 metro de altura, lefiosos, y notable por sus
bellas flores rojizas y digno de ser cultivado en jardines.”
The specific epithet is from the Greek words zuxvés, close and com-
pact, and ordxus, spike, in allusion to the narrowed dense panicle.

Molina, and Fred A. Barkley (No. 19An.340).
Habracanthus erythranthus bears a general resemblance to H.
scolnikae and may be closely related to it. The two species, however,
should be easy to separate. The corollas of H. scolnikae are sulphur
yellow, the segments of the calyx are tipped by several conspicuous
LEONARD—THE ACANTHACEAE OF COLOMBIA, III 439
glandular trichomes, the pedicels inconspicuously and very sparingly
hirtellous, and the leaf blades, even the lowermost, are of an ovate
type, whereas in H. erythranthus the corollas are red, the calyx seg-
ments are devoid of any glandular trichomes, the pedicels are densely
hirtellous with conspicuously septate hairs, and at least the lowermost
leaf blades are oblong-obovate or oblong-elliptic.
The specific epithet is from the Greek épvdpés, red, and avéos, flower,
alluding to the color of the corolla.

Type in the U. S. National Herbarium, No. 2045429, collected in
temperate forest, Cerro Negro, Hato Grande, on ridge east of
Rio Muchindote, 15 km. east of Gacheté, Department of Cundina-
marca, Colombia, 2,735 meters altitude, June 13, 1944, by Martin
L. Grant (No. 9439). Isotype: US.
The specific epithet is from the Greek yapiev, meaning slender and
graceful. Compared with other Colombian species, Habracanthus
charien is unique in its small rose corollas with narrow tube, small
throat, subequal lips (the upper lip relatively broad and not
contorted) and in its short, barely exserted stamens. The species
might possibly represent a new genus.

Type in the U. S. National Herbarium No. 2045439, collected in
subtropical forest on the Sierra Perij4, 6 km. east-northeast of
Manaure, 42 km. east of Valledupar and 7 km. from the Venezuelan
border, Department of Magdalena, Colombia, 1,735 meters altitude,
February 1, 1945, by Martin L. Grant (No. 10731). Isotype: US.
Oscar Haught’s No. 4510 (US), collected in “Africa,” Sierra Perijé,
Department of Magdalena, Colombia, about 1,500 meters altitude,
December 16, 1944, is also of this species. Haught states in his label
data that his plant was an erect herb up to 1.5 meters high, the flowers
very showy, either all red, or red tipped more or less with bright
yellow (in some plants more than half the corolla yellow), and that
the species was very abundant locally, growing along streams and on
moist slopes.
Habracanthus antipharmacus with its bicolored corollas suggests
at once Lindau’s H. diversicolor. The two species are closely related
but if carefully compared show certain differences. In H. diversicolor
LEONARD—THE ACANTHACEAE OF COLOMBIA, III 465
the leaf blades are rounded above the winged petiole instead of being
gradually narrowed into the petiole wing, and the inflorescence is
denser with the shorter ascending rigid branches, the branches of the
forks widely spreading. In H. antipharmacus the branches are slender,
spreading, recurved, and the branches of the forks are only slightly
spreading and longer and more slender.
Grant tells us that the root is used as a remedy for snake bite,
thus suggesting the specific epithet, av7--, against, and ¢4pyaxov, venom.

others known in the large lips of the corolla, and the long calyx
segments, which, like the inflorescence, are coarsely pubescent.

Habracanthus corei differs from the majority of the Colombian
species in its broadly elliptic leaf blades and the very sharply acu-

March 25, 1939, by Kjell von Sneidern (No. 2646).
Characters making Habracanthus congestus easy to separate from
other Colombian species are its narrow congested panicle, small red
flowers, and large ovate or obovate hairy leaf blades. The specific
name congestus alludes to the narrow dense panicles.

San Raphael, below Cerro Tatam4, Department of Caldas, Colombia,

Pennell (No. 10414).
Habracanthus pennellir is closely related to and resembles in many
respects H. scolnikae from the Department of Antioquia. In H.
pennellit the calyx lobes, although they bear scattered glandular
trichomes like H. scolnikae, are linear and abruptly acute instead of
being gradually narrowed from the base to a slender tip. The leaf
blades of H. scolnikae, although small and ovate like those of H.
pennellii, are acutely acuminate instead of subobtuse or bluntly short-
acuminate. The corollas also are different in the two species: H.
scolnikae has sulphur-yellow corollas reaching 15 mm. in length, where-
as those of H. pennellii are lake-red and not over 12 mm.long. Both
species are rank herbs with relatively thick tumid stems.
Only the uppermost leaves are represented by the type material
of H. pennellii. The lower stem leaves might possibly be much
larger than the dimensions given in the description.

Garcia-Barriga’s No. 4857, collected at Yanaca, Maripi, Depart-
ment of Antioquia, July 22, 1936, may also be of this species.
The relatively small thin leaf blades, numerous small delicate
panicles of sulphur yellow flowers, and all the main branches of the
panicles being subtended by small, sessile, cordate, pointed leaves are
characters marking Habracanthus scolnikae.

Justicia chrysocoma is closely related to J. rohrit, the inflorescences
of the two species being quite similar in general appearance. Several
striking differences exist, however. In J. chrysocoma, the leaf blades,
especially on the lower surface, the petioles, stems, and internodes
of the inflorescence are densely subtomentose with golden hairs,
the bracts, bractlets, and calyces, as well as the internodes of the
inflorescence, bear no patelliform hairs, and the corollas are pink or
red. On the other hand, in J. rohrii the stems are minutely puber-
ulous, the leaves are almost, if not entirely, glabrous, the bracts,
bractlets, and calyces, as well as the internodes of the inflorescence,
bear, in addition to the pointed hairs, some terminating in large
patelliform glands, and the corollas are white or yellowish. There
is also a marked difference in size. The plants of J. rohrii rarely
exceed 2 meters in height, whereas those of J. chrysocoma may reach
as much as 6 meters.
The characters delineating J. chrysocoma are not so well marked
in Haught’s No. 3947. A fair percentage of the hairs of the inflores-
cence is patelliform, and the tomentum is neither so dense nor of so

golden a yellow as in typical specimens. Haught’s plant seems to
be intermediate between J. chrysocoma and J. rohrii.
The specific epithet, chrysocoma, is from the Greek xpvadkopos,
golden-haired.

Lawrance (No. 60). Isotype: GH.
Justicia chaponensis is closely related to and resembles in some
respects J. hyperdasya and J. pampolystachys. The leaf blades of
these species are more of an ovate shape and the bracts subtending
the flowers are larger, elliptic or suborbicular in shape, and obtuse
and apiculate at the tip.
No corollas could be found on either of the two sheets cited, but
according to the label notes they were mauve with purple stripes.
They are probably small in size and somewhat similar to those of
the two related species.

Justicia unguiculata is easily recognized among other Colombian
species by its conspicuous ungulate ciliated bracts. These are strik-
ingly similar to those of Jacobinia azxiologa but are much smaller.
The closest relative is probably Justicia pilosa (Nees) Lindau of
Pert. This it resembles in many respects, especially as to the
inflorescences. The ovate leaf blades of the Peruvian species however
are much smaller, the uppermost barely exceeding the spikes or even
shorter, and gradually narrowed from below the middle to an obtuse
tip. In size they rarely exceed 5 cm. in length and 2.5 cm. in
width, whereas the thinner blades of J. wnguiculata are as much as
15 cm. long and 6 em. wide and are often slenderly acuminate.
The specific epithet, wnguiculata, alludes to the unguiculate or
clawed bracts.

Justicia hyperdasya is closely related to J. pampolystachys Leonard,
differing chiefly in its herbaceous nature, the white flowers, and
oblong or oblong-ovate leaf blades. J. pampolystachys is a shrub
with blue flowers and ovate leaf blades. The specific epithet is
derived from the greek brépdacus, meaning very hairy.

mm. long, 4 mm. broad at base, narrowed at 3 mm. above base to
3mm., thence gradually expanded to about 4 mm. at mouth, the upper
lip erect, triangular-ovate, about 10 mm. long and wide, rounded
and notched at tip, the lower lip spreading, up to 17 mm. long, 3-
lobed, the middle lobe 8 mm. wide, the lateral ones 7 mm. wide, all
ovate and rounded at tip; stamens exserted about 5 mm. beyond mouth

rounded at tip, this entire or coarsely erose; seeds only slightly flat-
tened, almost spherical, puberulous or glabrate, 2.5 to 3 mm. in diam-
eter, whitish, or black at maturity.
Justicia carthaginensis is usually found on slopes, in waste places,
and thickets, these occasionally coastal. Although more common at
lower altitudes, it has been found as high as 1,300 meters.
The species exhibits considerable variation. The upper lip of the
corollas of Killip and Smith’s No. 14711 was reported to be trans-
versely white-barred at center. This may be a common character,
but color markings are usually not apparent in dried herbarium
material. The width of the bracts is especially variable. For in-
stance, those of H. H. Smith’s No. 566 from Bonda are fully 7 mm. wide
with broadly rounded, almost truncate, and subemarginate apiculate
tips, and those of Pennell’s No. 2722 are barely 1 mm. wide and sub-
acute. The pubescence of most of the specimens cited is sparse,
but Haught’s No. 4391 from Fonseca is dense, and soft and velvety
to the touch. None of these characters, however, are consistent
enough to warrant the maintenance of varieties or forms.

Type in the U. S. National Herbarium, No. 1708866, collected near
stream in forest, vicinity of Manaure, Department of Magdalena, 700
meters altitude, April 13, 1944, by Oscar Haught (No. 4072).
Paratypes are Haught’s No. 3999 (US), collected near Barrancas,
170 meters altitude, February 16, 1944, and his No. .3816 (US),
collected in the forest 12 km. north of Codazzi, both localities in the
Department of Magdalena, and Schlim’s No. 887 (K), collected in
560 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM
forest at the foot of the Sierra Nevada, at Riohacha, Department of
Magdalena.
Haught tells us in his label notes that this species is strictly a forest
plant and is probably poisonous. It dries with a peach-kernel odor
and is not eaten by stock. The flowers are early deciduous, opening
in the early morning and falling by noon.
The spathulate bracts remind one of J. carthaginensis, but that
species does not have long-pedunculate inflorescences, and its bracts
are relatively narrower and the leaf blades smaller. The specific
epithet is from the Greek ¢appyaxédys, meaning poisonous.

Garcia-Barriga (No. 12353) describes the flowers of his collection
as being “amarillas.”” This may possibly be an error since some of
the bluish coloration still remains in one of the dried corollas. Aside
from this possible color variation, Garcia-Barriga’s specimen is
identical with the other specimens cited. The flowers of Haught’s
No. 1807 were rose, lined with white, showing that there is some
color variation.

Justica leucerythra bears a general resemblence to the Peruvian
species J. glabribracteata Lindau., but in that species the bracts are
relatively broader and often obtuse or rounded instead of sharply acute,
and the capsules are more or less hirtellous. The specific epithet is
from the Greek devxépvdpos, meaning pink, in allusion to the pink
corollas.

Justicia enarthrocoma is closely related to J. leucerythra, differing
in the subpanduriform leaf blades, the septate golden brown hairs on
stems and young leaf blades, and the much larger scarlet corollas,
these with a bilobed upper lip. The specific epithet is from the Greek

Justicia homoea has the same habit and general appearance as
J. phlebophylla Leonard (Haught, No. 4564); in fact, plants of the two
species were growing in the same colony. Both are slender shrubs 2
meters high, with large, almost glabrous, veiny leaves bearing numer-
ous conspicuous cystoliths. The spikes of the two species are, how-
ever, definitely dissimilar. Those of J. homoea have oblong, slightly
obovate, strongly nerved bracts up to 11 mm. long and 4.25 mm. wide
and the flowers are 4-ranked; in J. phlebophylla the flowers are secund
and the bracts are ovate and 3 mm. long and 1.5 mm. wide. The
corolla of the latter is purple, marked with light lines; that of J.
homoea is rose color. The specific epithet is from the Greek word
$no.os, meaning similar, in allusion to its resemblance to J. phlebophylla.

The heavy brownish bifarious pilosity of the stems, the large
oblong-elliptic short-acuminate leaf blades, and the white corollas are
characters of Justicia filibracteolata var. leucantha which readily
separate it from the typical variety. Pennell’s No. 1714 was collected
between 1,100 and 1,300 meters, the other specimens cited were from
between 350 and 500 meters. The specific epithet leucantha is from
the greek devxds, white, and &v6os, flower.

Giiamués, Comisarfa of Putumayo, Colombia, 330 meters altitude,
December 18, 1940, by J. Cuatrecasas (No. 11157).
Justicia pelianthia is readily recognized by its large erect purplish
corollas, by the flowers being secund in short spikes, these forming a
broad, rather flat panicle, and by the minute golden-brown pubescence
of the panicle branches. Apparently it has no close relatives among
the Colombian species. The specific epithet is from the Greek
meds, livid, and é&vOeov, blossom.

Justicia jacobinioides may be related to J. aurantiaca. The two
species have similar calyces and anthers, and the corollas are of the
same general shape. The corollas of J. aurantiaca, however, are strictly
glabrous instead of rather densely puberulous and the leaf blades are
much larger, thinner, and glabrous. Moreover, the inflorescence of
J. jacobinioides is axillary, whereas in J. aurantiaca it is terminal and
more compound.

Justicia secunda, common in the West Indies but rare in Colombia,
is very closely related to Lindau’s J. filibracteolata. Superficially the
two species resemble each other very closely, differing in the shorter
bracts and bractlets of J. secunda. In J. filibracteolata the panicles
usually remain compact and the branches of the inflorescence do not
tend to become elongated as in J. secunda.

Justicia atacta has a strong superficial resemblance to a Pseuder-
anthemum, having panduriform leaf blades and a long very slender
inflorescence, the extremely small spicate or paniculate branches
simulating the clusters of pediceled flowers in Pseuderanthemum.
Yet a close examination of the flowers reveals superposed anther
lobes, the lower one tailed, and no staminodes.
The specific epithet is from the Greek éraxros, meaning irregular
or atypical.

Justicia ephemera is a well-marked species apparently without near
relatives. The panduriform leaf blades are like many of those in
Pseuderanthemum. Staminodes, however, so constant in Pseuder-
anthemum, are definitely absent in this species. Haught states that
the flowers are fragrant forming a showy inflorescence during the
mornings but falling by afternoon. The plant is said to be in bloom
only two or three days. The specific epithet is from the Greek
word éjuepos, meaning ephemeral or short-lived, in allusion to the
fugacious blossoms.

December 17, 1940, by J. Cuatrecasas (No. 11137).
Also of this species is Cuatrecasas’ No. 10933 (Col), collected in
wet forests of the Rfo San Miguel at the mouth of the Rio Conejo,
Colombian-Ecuadorian border, 300 meters altitude, December 9, 1940,
and Sprague 396 (K), collected at Mocoa, Putumayo, May 25, 1899.
Justicia chloanantha has no close relatives among the Colombian
species. A similarity of the inflorescences suggests Justicia cuzcoensis
Lindau of Pert, but that species has much smaller, ovate, and more
hairy leaf blades (up to 9 cm. long and 4 cm. wide) and yellowish
white and purplish corollas. The specific epithet is from the Greek
xAoaves, greenish, and av6os, flower.

Justicia helonoma has no close relatives among the species treated
in this paper. The large, more or less succulent, glabrous leaf blades
and narrow panicled spikes of purplish flowers should serve as char-
acters by which it can be readily recognized. The specific epithet
is from the Greek word édovéyos, alluding to the swampy habitat.

Justicia pectoralis is closely related to J. comata, but typical plants
of the former can be readily recognized by their terminal inflorescence
with subterete glandular puberulous branches. The inflorescence of
J. comata, on the other hand, is often both terminal and lateral with
flattened branches, these hirtellous, usually bearing few if any gland-
ular hairs.
The species is found in woods, waste places, and in cultivated fields

LEONARD—THE ACANTHACEAE OF COLOMBIA, III 617
Justicia comata, distributed throughout tropical America, generally
grows at low elevations of 500 meters or less, but may be found
occasionally as high as 2,000 meters. It is weedy in nature, and is
equally at home in damp or dryish thickets, on slopes, in woods, on
river banks, in waste places in general, on margins of ponds or small
streams, or even growing in shallow water. As to be expected of a
species of such an extensive range, considerable variation is exhibited.
Plants in wet situations, especially those growing in water, tend to
produce long narrow leaf blades gradually narrowed to a subsessile
base. Killip’s No. 34261 and von Sneidern’s Nos. 494 and 2644 are
plants of this nature. The leaf blades of these plants vary from 4 to
17 cm. in length but rarely exceed 13 mm. in width. Moreover, Killip’s
specimen shows a transition stage between the aquatic form and the
typical form, which has broader blades with rounded or obtuse bases.
Plants with strictly terminal inflorescences rather strongly hirtellous
or even puberulous with a predominance of glandular hairs are likely
to be confused with J. pectoralis. Killip & Garcia’s No. 33598 is
such a plant. Remarkable also is the development of pilosity in
Pennell’s No. 1473 and Killip & Smith’s No. 14719. In these the
hairs of the stems are white, spreading, straight, and up to 3.5 mm.
long.

its narrowly lanceolate leaf blades and numerous axillary panicles
with slender branches and the subulate calyx segments. The specific
epithet is derived from the Greek words vaya, running water, and
dtdos, loving.

Justicia martiana is closely related to J. comosa but can be easily
recognized by its large dense hirsute panicles. The species shows
considerable variation. The flowers vary from white to blue. Schom-
burgk’s No. 305, the type of var. hispida Nees, from French Guiana,
has a glandular pubescent inflorescence and ovate leaf blades with
rounded or subcordate bases. Klug’s specimens, cited here, have
slenderly lanceolate leaf blades gradually narrowed to the base, but
those of Uribe-P., although likewise narrowly lanceolate, are rounded
at base and briefly decurrent on the petiole. The capsules of Schom-
burgk’s plant are 4 mm. long, 2.25 mm. wide, and about 1 mm. thick,
short-clavate and rather densely hirtellous.

Justicia laevilinguis, a plant of swampy regions, is widely distrib-
uted throughout tropical America. In spite of its great range, speci-
mens are not often collected, probably because it is not abundant
in any particular place. The specimens cited were all from below 50
meters altitude.
Its broad strongly flattened capsules and thin orbicular eray or
brown flecked, thin-margined seeds are unique.

Type in the U.S. National Herbarium, No. 1798533, collected in
damp forests along the Rio Putumayo at Puerto Porvenir, Comisaria
of Putumayo, Colombia, 230 to 250 meters altitude, November 22,
1940, by J. Cuatrecasas (No. 10757).
The following specimens also may be of this species: Klug’s No.
1813, collected in the forests of Umbria, Comisaria of Putumayo,
325 meters altitude, October or November 1930, and Richard Evans
Schultes’ No. 3538, collected along the Rio San Miguel, in the vicinity
of Conejo, Putumayo, 300 meters altitude, April 2-5, 1942.
Klug’s specimen differs from the type in its lilac and red-brown
(not white) flowers and in the slightly wider and more slenderly
stipitate bracts. It does not seem expedient, however, to assign
specific or varietal rank to this plant until further material can be
examined.
Schultes’ specimen was taken from a large herb and was called
in the Kofén vernacular, ‘chu-ru-ko-pu.”
The specific epithet is from the Greek idoyerys, meaning peculiar
of its kind, in allusion to the peculiar curved secund spikes.

Justicia fusagasugana is closely related to and superficially resembles
the Mexican J. furcata Jacq. The habit of growth, leaf blades, stems,
and inflorescences of the two species are very similar. The bracts
and calyces are, however, definitely different. In J. furcata, the bracts
are thick, narrowly obovate, up to 3 mm. wide and broadest above the
middle, acute at tip, the costa prominent, and the calyces are notice-
ably larger and their segments oblong instead of slenderly acuminate.

Justicia killipii is closely related to J. sterea Leonard but can be
separated by its smaller size, the more ovate-shaped leaves and the
much larger spikes. The plants of J. sterea often exceed 70 cm. in
height, thus being at least twice as high as those of J. killipid; their
elliptic leaves are up to 13.5 cm. long and 5.5 cm. wide instead of only
9 cm. long and 4.8 cm. wide, and their spikes are only 3 em. long
instead of 7 cm.

Justicia graphophylla bears a close relationship to J. phlebophylla
and resembles it in many respects, especially in the large glabrous or
nearly glabrous leaf blades, these densely covered by cystoliths. In
J. phlebophylla, the rachis of the spike is heavy and the flowers
secund; the rachis does not show any tendency to fragmentation
as in J. graphophylla. The specific epithet is from the Greek
ypadw, engrave or draw, and ¢iAdov, leaf, in allusion to the design
formed by the conspicuous cystoliths.

Type in the U. S. National Herbarium, No. 1850311, collected
in the valley of the Rio Cubugén, between El Carafio and El Indio, in
the vicinity of Sarare, Department of Norte de Santander, Colombia,
470 to 600 meters altitude, November 12, 1941, by J. Cuatrecasas
(No. 13061).
Justicia stereostachya can be easily recognized by its rigid spikes,
densely glandular corollas with swollen plaited throat, and by the
leathery leaf blades. The specific epithet is from the greek orepeds,
rigid, and ordxvus, spike.

Isotype: Med.
Justicia hodgei resembles and may be related to J. sterea. The
latter species has, however, a forked spike and white corollas, these
rather sparingly pubescent with slender hairs. In JJ. hodgei the spikes
are simple and the corollas are lavender and densely clothed with
minute spreading rigid hairs. Because of the scarcity of material it
was not desirable to dissect the single immature corolla and capsule.

Type in the U.S. National Herbarium, No. 1798535, collected in
wet forests along the Rio Putumayo at Puerto Ospina, Comisarfa of
Putumayo, Colombia, 230 meters altitude, November 29, 1940, by
J. Cuatrecasas (No. 10848).
The holotype specimen is forked at the tip, the two branches about
20 cm. long and each bearing at the tip of the single internode (about
12 cm. long) a pair of leaves and an inflorescence. This mode of
forking may or may not be normal for the species. The lobation of
the lips was not discernible in the immature corollas of the type
material. The species apparently has no close relatives and is
probably confined to the Putumayo region. The specific epithet is
from the Greek word bypé8i0s, meaning “living in wet places.”

LEONARD—THE ACANTHACEAE OF COLOMBIA, III 647
Justicia sp.
E. P. Killip & Hernando Garcia’s No. 33571 undoubtedly represents
an undescribed species of Justicia. Their specimens were collected in
dense forest along the Quebrada Jillita, Department of Chocé, 50-100
meters altitude, February 1939. The plant from which the specimens
were taken was about 50 cm. high and bore white flowers. Collo-
quially called ‘“‘yerbabuenilla,” it was used as a remedy for snake bites.
The specimen deposited in the National Herbarium is an ascending
branched herb about 40 cm. high, the stems subquadrangular, bi-
fariously hirtellous with retrorsely curved white septate hairs up to
0.22 mm. long; the internodes of the stem are short and rather
numerous, not exceeding 2 cm. in length. The leaf blades are ovate,
up to 23 mm. long and 14 mm. wide, obtuse or rounded at tip and
narrowed at base, rather firm, entire or undulate, nitid, glabrous or
the margins and the costa and lateral nerves (these moderately con-
spicuous) bearing a few rigid ascending ‘hairs about 0.2 mm. long;
petioles thick, about 1.5 mm. long, sparingly hirtellous. The speci-
men examined was definitely sterile without the faintest vestige of a
flower.

Pelecostemon differs from Justicia in its peculiar anthers. The
name, of Greek origin and derived from ré\exus, halberd, and OTH MWY,
stamen, was suggested by a fancied resemblance of the anther to a
certain type of ancient battle-ax.

Jacobinia aziologa apparently has no close relative in Colombia.
It is readily recognizable by its peculiar orbicular apiculate clawed
bracts. Hodge states that the flowers of his No. 6511 were creamy
white. The specific epithet is from the Greek 4£6\oyos, meaning
remarkable or worthy of mention.

Type in the U. S. National Herbarium, No. 1950034, collected at
Aguabonita, valley of the Rio San José, in the vicinity of Moscopan,
Department of Cauca, Colombia, 2,280 meters altitude, January 30,
1947, by J. Cuatrecasas (No. 23467).
Fosberg’s No. 20115 (US), collected in a wet forest on a flat ridge-
top northwest of Quebrada la Candela, Rio Naranjo, 20 km. southwest
of San Agustin, Department of Huila, Colombia, 2,100 to 2,300 meters
altitude, February 13, 1943, is also of this species.
Cuatrecasas gives on his label the following notes: “Suffrutex 1
met. Hoja verde brillante, haz verde grisaceo envés, peciolo y
nervios violdiceos. Caliz amarillo con méargenes verdosos. Corola
amarilla. Anteras violetas.”
Fosberg’s collection was from an herb less than a meter tall with a
yellow-green calyx and yellow corolla.
This species is doubtfully placed in the family Acanthaceae. Should
it belong in the genus Jacobinia, the shallowly toothed leaves and the
lack of cystoliths and bractlets would be unique. The specific name
is from the Greek d&udiBodos, meaning ambiguous or doubtful.

Jacobinia tinctoria is a cultivated plant in Colombia often planted
in parks, gardens, or patios. The leaves and young branches
macerated in water yield a deep blue dye which in a diluted solution
can be used as a substitute for indigo for washing white clothes.
The species occurs more frequently in Central America, where it may
have originated.

DOUBTFUL SPECIES
Jacobinia lindaviana Rusby
Jacobinia lindaviana Rusby, Deser. So. Am. Pl. 128. 1920.
The type has not been available for study. Following is the orig-
inal description:
“A glabrous shrub, the branchlets short, stout and leafy. Petioles 3 mm.
long, slender; blades 15-30 mm. long, 10-20 mm. wide, ovate, rounded at the
base, obtuse at summit, dark-green, thickish, the veins dark, strongly ascending.
Flowers few, in the upper axils, subsessile, 2-bracteolate at the base of the calyx,
the bracts minute, subulate. Calyx 10 mm. long, the lobes lanceolate, acuminate,
acutish. Corolla-tube 15 mm. long, nearly straight, dilating very near the
summit, the lobes partially destroyed by insects in my specimen. The short
stamens equalling the corolla tube, the longer ones exserted, the lower anther
cell with about two-thirds of its length below the base of the upper, which is
short mucronate. Style not equalling the longer stamens, stout, sharply declined,
above.
“Species dedicated to Dr. Lindau who has kindly confirmed my determination.

hillside on June 6, 1899, by Herbert H. Smith, who reports it as a foot high, and
having crimson Flowers. (No. 2821).”
39. CHAETOCHLAMYS Lindau
Chaetochlamys Lindau in Bull. Herb. Boiss. 3: 490. 1895. From the Greek
xairn, hair, and xAauis, bract. The name was probably suggested by the
rather conspicuous filiform bracts and bractlets. The genus is based on
3 species, C. macrosiphon (Kuntze s. n., Bolivia), C. marginata (Kuntze s. n.,
Paraguay), and C. rusbyi (Kuntze s. n., Bolivia). The first of these can be
considered as the type species.
Herbs or suffrutescent plants; leaf blades ovate to lanceolate;
flowers borne in short spikes, these crowded in a terminal congested
head; bracts and bractlets narrow; calyx segments 5, narrow; corolla
hypocrateriform, the limb 2-lipped, the upper lip 2-lobed, the lower
lip 3-lobed; stamens 2, exserted, the anther lobes affixed at different
heights, the lower lobe spurred; stigma capitate; capsules clavate,
4-seeded.
Some 14 species have been described in this genus, all from tropical
America.

tocantinus Nees. Type collected on the Rio Tocantins, Province of Goyaz,
Brazil, by Pohl. Derivation of epithet: xairn, hair, and @ddat, sack, in
allusion to the vestigial lower anther lobe. In plate 26 this is pictured as a
short hair, although in most species the lower lobe is shaped much like the
upper but much smaller and evidently sterile.
Herbs; leaf blades ovate to oblong; flowers more or less secund,
borne in short dense terminal and axillary spikes, these often forming
panicles; bracts narrow, ending in filiform tips, hirtellous and ciliate;
calyx segments 4, resembling the bracts; corollas white or some shade
of purple, finely pubescent, the tube narrow, the lips subequal, the
upper lip narrowly ovate, the lower deeply 3-lobed, the lobes rounded;
stamens, slightly exserted but not exceeding the corolla lips, the
upper anther lobe oblong, 1-celled, the lower lobe reduced or vestigial,
or, 2s in the type species, hairlike, the lobes separated by a slender
filiform connective; capsule clavate, 4-seeded; seed papillose or
otherwise roughened.
About a dozen species are now recognized, these all confined to

Staurogyne leptocaulis is readily distinguishable from S. lepida-
gathoides Leonard (described from the Department of Bolivar) by
its slenderer spikes and narrower leaf blades. In S. lepidagathoides
the latter are as much as 7.5 cm. long and 2.5 cm. wide. The specific
name is from the Greek demrés, slender, and xavdés, stem.

Mendoncia lasiophyta is a rampant liana, clambering over grasses
and low shrubs. The leaf blades are large, orbicular or suborbicular,
and firm, but somewhat papery, and the lanceolate bracts, up to 4 cm.
long are, like the stout peduncles, clothed with a dense yellowish
brown tomentum. The corollas, exserted for about half their length
beyond the bracts, are red. The specific epithet, derived from dasios,

along the Rio Anchicayé, Department of El Valle, Colombia, by
J. Cuatrecasas (No. 15216). From this M. trichota differs in its
predominantly longer hairs, the dense (under lens) understory of
minute hairs on the stems, the larger leaf blades, and the smaller
bracts. The leaf blades of M. cordata are up to 20 cm. long and
14 cm. wide and the hairs of the under surface are denser, giving it a
velvety touch that is lacking in M. trichota, with its more scattered
hairs. The bracts of M/. cordata are as much as 3.5 cm. long and 2.5
cm. wide, but in M. trichota do not exceed 3 cm. in length and 1.7 cm.
in width.
The specific epithet is from the Greek word rpixwrés, meaning
provided with hairs.

Mendoncia phalacra is unique in being strictly glabrous and in the
rounded, more or less recurved, mucronulate tips of the bracts, which
are very noticeable. The species has no close relatives among those
known to grow in Colombia. The specific epithet is from the Greek
word ¢adaxpés, meaning smooth or glabrous.

however, when this genus was added to the list of nomina conservanda
the etymologically correct spelling Phauwlopsis was adopted. The
specific epithet parviflora was superfluous when published, and must
be replaced by the earlier oppositifolia. The fact that the genus
Micranthus Wendland has been rejected in favor of Phaulopsis does
not render specific names published unter Micranthus illegitimate.

The above citation is the first publication, two years earlier than
that cited above on page 89, i. e. Nees in DC. Prodr. 11: 206. 1847.
This brings up a peculiar nomenclatural difficulty. Bentham was
preparing his list of the British Guiana collections of Schomburgk,
and Nees contributed a description of his proposed new species in
advance of its intended publication in the Prodromus. The Bentham
publication came out earlier, but it does not cite the intended type
(a Humboldt collection from the Aragua Valley, Venezuela), but only
a Schomburgk collection from British Guiana, which Nees was con-
sidering a new variety—S. humboldtianus var. 8. ‘The short specific
description is however based on the Humboldt specimen, even though
this is not cited, and consequently it must be considered the type.
The Schomburgk specimen has not been examined; it very probably
represents a different species.

In DC. Prodromus, Nees lists under the typical variety (called
var. a) a Linden collection (Linden 1526) from Cuba. This was an
error; Nees very likely intended to list this specimen under his var. 8.
In any case, this collection, as shown by a photograph of a specimen,
does not represent 22. humboldtiana. On page 89 above, I stated that
it might be an undescribed species, but further study indicates that
it is R. macrophylla Vahl, a species rather common in Cuba.

Ruellia macarenensis resembles in a general way FR. puri Mart.
of Brazil, but that species has longer corollas with a much more slen-
der tube (lower narrow portion 1 mm. broad and as much as 5 em. long
and the expanded upper portion about 1 em. long and 5 mm. wide at
mouth) and its leaf blades are less slenderly acuminate and falcate.
The plants from which the type specimens were obtained were
hanging from the steep river bank. They were sparingly branched
and were from 0.5 to 1.5 meters long.

tube, the filaments of the longer pair about 7 mm. in length, those of
the shorter pair 5 mm., all glabrous, the anthers 2.5 mm. long, 0.5
mm. broad; stigma reaching the tip of the shorter pair of stamens,
the developed lobe flat, oblong, rounded; ovary and style hirtellous

Type in the Kew Herbarium, collected in a dense jungle near shore
of Gorgona Island (west of Cauca), Colombia, Oct. 8, 1942, by L. E.
Cheesman (No. 533).
C. Longfield’s No. 381, collected in a clearing formed by fallen trees
in an old wet jungle near seashore of Gorgona Island, ‘11-7-24,” is
also of this species.
fiuellia gorgonensis is probably related to R. putumayensis, which
it rather closely resembles. The leaf blades of R. putumayensis,
however, are elliptic rather than ovate and the corolla white and
striped with lilac.

PART II
15. NERIACANTHUS Benth.
S. Moore (Journ. Bot. Brit. & For. 65: 221. 1927) reduced the genus
Neriacanthus to Salpinzantha Hooker (Bot. Mag. Curtis pl. 4158. 1845),
but I am inclined to regard the two as distinct. Neriacanthus has
dense spikes with large, closely imbricated, ascending bracts, and
corollas with narrow tubes abruptly expanding into a rather con-
spicuous limb. ‘These characters contrast strongly with those of
Salpinzantha, which has loose spikes with distant spreading flowers
LEONARD—THE ACANTHACEAE OF COLOMBIA, II 699
subtended by minute bracts, and corollas with gradually expanded
tubes and relatively small lobes, which do not form a sharply dif-
ferentiated limb.

Stenandrium humboldtianum Nees, DC. Prodr. 11: 284. 1847. Type collected
at ‘‘Atures, Maypures’” by Humboldt. Atures is on the east bank of the
Rio Orinoco and in Territorio Federal of Amazonas, Venezuela, but Maypures
is located on the west bank several miles south of Atures in the Comisaria,
of Vichada in Colombia. Thus the exact type locality is uncertain.

stems woody at base, 5 mm. in diameter (the internodes 1 to 2.5 cm.
long), decumbent, pilose, the upper part densely so, the hairs spreading,

cylindrical, 15 mm. long, 2.25 mm. broad at base, rather abruptly
narrowed to 1 mm. just above base, expanding at throat to about 2
mm., the lobes subequal, obcordate, 6 mm. long, 5.5 mm. wide,

8 mm. long, 4 mm. broad, 2 mm. thick, glabrous, yellowish, nitid,
bearing several irregular purple spots near tip of each valve; retinacula
about 2 mm. long, slender and cucullate at tip; seeds reddish-brown,
ovoid, oblique at base, 3 mm. long, 2.5 mm. wide, 0.75 mm. thick,

Stenandrium humboldtianum Nees is definitely caulescent, even
though Nees starts his description with the word “acaule.” The
photograph of Humboldt’s specimen in the Berlin Herbarium, the
specimen cited by Nees, shows, in addition to a flowering tip of a
plant, a section of stem (about 6 cm. long) with a pair of attached
leaves.

Aphelandra gilva is close to A. porphyrocarpa, but distinct from
this species in its acute calyx segments and incised leaf blades. In
A. porphyrocarpa the calyx segments are rounded, mucronate and
dentate at tip, and the leaf blades are shallowly incised. The specific
epithet gilva, pale yellow, alludes to the color of the corolla.

plant to belong to a new genus to be inserted after Acanthaceae genus
No. 80 [Lagochilium]; the “no. 5” indicates the species, which is
actually in the catalog No. 5 of Lagochilium. The Triana specimen
from San Pablo cited above as possibly the same species is Lagochilium
No. 6 of the catalog.

Aphelandra andrei belongs to the Lagochilium group of Nees, plants
midway between Stenandrium and Aphelandra. It is probably near-
est to A. botanodes, as indicated by its small size, herbaceous habit,
and trifurcate inflorescences of 3 small spikes. It differs strikingly,

however, from that species in its rather densely hirsute stems and
entire bracts.

Aphelandra phalacra is very closely related to A. lonchochlamys
and may be merely a form of that species. It differs in being strictly
glabrous in all parts except for a very minute and inconspicuous
papillar puberulence sometimes present on the bracts. The leaf
blades are relatively shorter and broader.
The specific epithet is from the Greek ¢adaxpés, meaning smooth.
The flowers are too poorly preserved to describe the lips; their
color is not apparent in the dried material.

Aphelandra grantii is closely related to A. parvispica. Its leaf
blades are larger than those of A. parvispica, reaching 23 em. in
length and 6.5 cm. in width, whereas those of A. parvispica do not
exceed 19 cm. in length or 5 cm. in width. The color of the corolla
is orange-scarlet, in contrast with the red flowers of A. parvispica,
LEONARD—THE ACANTHACEAE OF COLOMBIA, III 721
and the stems, especially the upper portions, are noticeably pilose
instead of being essentially glabrous. Its spikes are broader and the
ocelli are relatively large and conspicuous under a lens; in A. parvispica
the ocelli are small or even lacking.

Alphelandra coccinantha would follow A. macrophylla in the key.
It differs, however, from that species in its relatively shorter leaf
blades, these evenly and rather densely hirsute beneath instead of
glabrous or subglabrous. In A. macrophylla, furthermore, the panicles
are smaller and the spikes are noticeably shorter and thicker, and,
lastly, the corollas are orange-red instead of scarlet asin A. coccinantha.
The specific epithet is from the Greek kdkkwvos, scarlet, and dros,
flower.

It appears that the citation given above on page 292, 1. e., Radlk.
in Sitzungsb. Math. Phys. Kl. Akad. Wiss. Miinchen 13: 289. 1883,
is incorréct, even though it is the one usually given. At this place
the name is a nomen nudum, for there is only a listing of species and no
description. Nor is there any reference to a description of the genus
under another name. Pseuderanthemum is said to be the Eranthemum
of authors not Linnaeus, and there is mention of Nees’ treatment (in
DC. Prodromus), but Nees included in Eranthemum the species of
true Hranthemum as well as those that Radlkofer wished to separate
as Pseuderanthemum, and did not provide any description of the latter
as a group. The species were mostly those grouped by Nees and
LEONARD—THE ACANTHACEAE OF COLOMBIA, III 729
briefly characterized as ‘‘Parvibracteatae,” but included also a species
(E. palatiferum) from another section of the genus. Radlkofer gave a
reference also to two papers by T. Anderson, but at these places
Anderson merely listed several species as Hranthemum and did not
give any generic description. Apparently, the first valid publication
of Pseuderanthemum must be attributed to Lindau, and the citation
will be:
Pseuderanthemum Radlkofer ex Lindau, in Engler & Prantl, Nat. Pflanzenfam.
IV. 3b: 330. 1895.
No one species seems to have a particular claim as a lectotype, and
so the species illustrated by Lindau (op. cit. fig. 183), P. bicolor

casas (No. 16433).
Collected also in the same general region are the following: In

ventura, 40 meters altitude, February 15, 1939, H. P. Killip and

December 24, 1946, Haught, No. 5390 (US). ‘Andes de Mariquita,
Antioquia,” 2,200 meters altitude, February 1852, Triana (K).
According to the label notes, Haught’s No. 5390 was taken from an
epiphyte with very succulent shoots 1 meter long and having a showy
purple inflorescence, and his No. 5323 was taken from an erect
suffrutescent plant 1 meter high or less which possessed a showy
inflorescence with the axes and flowers light purple. Killip and Garcia
describe their No. 33318 as an herb 80 cm. high, the stems in clusters
bearing distichous panicles, and with both flowers and inflorescence
branches pink. The type sheet bears the following note: “Sufrutex
de ramas erguidas 1 m.; hojas rugosas, verde grisdceas; bracteas,
céliz y corola lilas.”’
Pseuderanthemum ctenospermum can be easily recognized by its
peculiar crested seed and rather large rugose leaves. This comblike
crest suggests the specific epithet taken from the Greek xreis, comb,
and ozépya, seed.

Pseuderanthemum chilianthium must be an attractive plant with its
large dense panicles of lilac flowers. Archer states that the pedicels
are also colored like the corollas. Archer’s No. 2120, representing
the small flowered form, has lavender colollas with darker stripes on
the lobes. The plant of the holotype had leaves deep purple beneath.
More material should be examined before any of these variations can
be used as characters on which to base varieties or closely related
species. The specific epithet is from the Greek xtdo-, thousand, and
&vdeov, blossom, in allusion to its numerous flowers.

Type in the Kew Herbarium, collected in a forest glade along the
Rio Sucio, between Dabeiba and Uramita, Department of Antioquia,
Colombia, 400 to 800 meters altitude, October 1891, by F. C. Lehmann
(No. 7266).
According to Lehman’s notes the plants of this species are ‘Weeds
up to 1 m. in height with profusely ramified and thin stems.” The
leaves are “dark sap-green” and the flowers ‘“‘ilac-red.”’
The specific epithet is from the Greek xAadwdns, abounding in young
shoots, in allusion to the branching habit of the plant.

Type in the U. S. National Herbarium, No. 2144877, collected
in Cafio Unguyd, at Jino-Gojé, between the Rios Piraparand and
Popeyak&, tributaries of Rio Apaporis, Amazonas-Vaupés, Colombia,
250 meters altitude, September 3-11, 1952, by H. Garcfa-Barriga
(No. 14377).
In many respects Pseuderanthemum galbanum resembles P.
poecilanthum; the inflorescence, the shape and size of the bracts
and bractlets, and the pubescence of the two species are practically
identical. There are, however, several striking differences. P.
poecilanthum is herbaceous, rarely if ever exceeding 30 cm. in height,
the leaves are relatively smaller, and the flowers white with conspicu-
ously purple-spotted lobes. In contrast, P. galbanum is a shrub or
small tree as much as 3 meters high; its leaves are relatively larger,
and the corollas are greenish yellow. It is to the color of the corolla
that the specific epithet, galbanum, alludes.

Pseuderanthemum thelothriz is near P. chaponense in its relationship
and general appearance. The pedicels of P. chaponense, however,
do not exceed 1 mm. in length, whereas in this new species they are
noticeably slender and are usually as much as 5 mm. long.
The specific epithet is from the Greek 67, nipple, and 6pié, hair,
in allusion to the papillose puberulence of the corolla.
