120 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
stipitate, slightly arcuate, densely cano-pubescent or fulvous-pubescent, provided 
at the base with a very short cuplike disk; style glabrous, about 1.3 mm, long. 
Fruit not known. 
Type in the U. 8. National Herbarium, no, 704057, collected in Santa Marta, 
Colombia, 1898-9, by H. H. Smith (no. 2083). 
This species is remarkable for the size and branching of its inflorescence and 
for its small, numerous flowers.

Figure 57. 
A shrub or small tree, almost unarmed, the branchlets terete, at first ferru- 
ginous-pubescent. 
Leaves 17 to 25-foliolate, the rachis slender, subcanaliculate, 7 to 10 em. long, 
ferruginous-pubescent. Leaflets membranous or subcoriaceous, the petiolules 
hairy, not over 1 mm, long, the blades oblique-oblong, 
cuneate or somewhat rounded at the base; rounded- 
emarginate at the apex, 1.2 to 2.5 cm. long, 6 to 10 mm. 
broad, more or less puberulous on both faces, paler be- 
neath; veins rather distant, running into the marginal 
nerve, but branched and_ distinctly anastomosed. 
Stipules broadly triangular, acute, indurate and sub- 
spinescent, very caducous, 
Inflorescence paniculate, axillary or terminal, 6 to 8 
cm. long (shorter than the leaves), simple-branched, 
the rachis rufous-tomentose; peduncles solitary .or in

longer, acute. Petals purple, glabrous; standard reflexed, 
the claw about 2 mm. long, the blade ovate, broadly rounded at the base, rounded- 
emarginate at the apex, about 8 mm. long and 7.5 mm. broad; wings oblique, 
falcate, 1-auriculate, the claw 1.5 to 2 mm. long, the blade 7 mm. long, 8 mm. 
broad; carinal petals faleate, 1-auriculate, subacute at the apex, the claw 1.5 
mm. long, the blade 7 to 7.5 mm. long, 3 mm. broad. Stamens monadelphous, 
glabrous, the fllaments thick, the anthers small, ovoid. Ovary stipitate, strongly 
arcuate, densely villous-tomentose; style glabrous, about 5 mm. long. 
Legume (fide Bentham) about 5 cm. long, the seminal part strongly bent, 
10.5 to 11.5 mm. broad, the wing straight, about 17 mm. broad. 
Type from Colonia Tovar, Venezuela, collected in flower by Fendler (no. 
1750’). The above description is after the specimen of this collection in the 
Gray Herbarium. The fruits, which I have not seen, were described from 
Fendler’s specimens (no. 1866’) from the same locality or from Moritz’s no. 883, 
also from Venezuela, without further indication of locality. 
Other specimens of the same species have been collected at the foot of the 
Cordillera de Santa Marta, Colombia, by H. H. Smith (no. 14). In these the 
leaflets are coriaceous and much larger than in the type, but the floral char- 
acters agree perfectly. The pubescence of the leaves, also, is decidedly less 
marked. 
The venation of the leaflets undoubtedly places this species among the 
Oblonga. According to Bentham the base of the pod is like that of a Drepano- 
carpus on a small scale, while the wing is that of Machaerium.
