PITTIER—-MIDDLE AMERICAN SPECIES OF LONCHOCARPUS. 89 
The specimens examined are Johnston 22 and Johnston & Miller 257, collected 
at El Valle, Island of Margarita, Venezuela, in July and August, 1901. 
This species is the type of the genus Lonchocarpus. It differs strikingly from L. 
benthamianus, of the West Indies, in the size of the leaves, the number, shape, and 
size of the leaflets, the coloration of the petals, the indument of the pistil, the number 
of the ovules, and several minor details. The transparent dots of the leaflets extend 
to the petals and on the former are conspicuous on the surface as minute black spots. 
The dark spot at the base of the standard, quite visible in dry specimens, is also a good 
distinctive character. 
Margarita Island lies very close to the coast of Paria, and not far from Cuman4, the 
type locality of the species. Notwithstanding slight discrepancies in the details, 
there can hardly be a doubt as to the identity of the specimens described above with 
the tree reported by Bonpland. Like that of L. benthamianus, the distributional area 
of this species seems to be very restricted. The tree has been reported from other 
parts of Venezuela under the vernacular name ‘‘aco,’’ which, however, may apply to 
several species.

Section Densiflori. A deciduous tree, the branchlets stout, grayish, glabrous. 
Leaves 7-foliolate, the rachis broadly canaliculate (the channel aristate at the bot- 
tom), glabrous, 17 to 25 cm. long. Leaflets coriaceous, the petiolules thick, 6 mm.

apex, 8 to 16 cm. long, 5 to 6.5 cm. broad, dark 
green, glabrous, and more or less lustrous above, 
paler and glabrescent or sparsely pilosulous (on 
the costa principally) beneath; costa and veins 
slightly prominent on both sides. 
Racemes axillary on the defoliate nodes, the 
rachis mostly thick, arcuate, rigid, about 18 cm. 
long, ferruginous or grayish-pubescent. Pedun-

less distinctly pale-striped longitudinally. Petals 
purple, shading to white toward the base; standard orbicular, emarginate and promi- 
nently callous-plicate at the base, concave, broadly rounded and slightly emarginate 
at the apex, densely white-spotted, softly pubescent without, the claw 4.5 mm. long, 
the blade about 12 mm. long and 14 mm. broad; wings strongly arcuate-falcate, auricu- 
late, sparsely white-spotted, glabrous or slightly pubescent; carinal petals falcate, 
concavo-convex and bulging toward the outside at the base, subauriculate, subobtuse 
at the apex, densely gray-pubescent along the keel, the carinal margin strongly 
arcuate, the claw 6 mm. long, the blade about 14 mm. long and 6.5 mm. broad. 
Staminal tube glabrous, slightly dilated and the vexillar stamen narrow at the base, 
the fenestrelle narrowing in a V-form at the apex. Ovary linear, stipitate, arcuate, 
gray-pubescent, about 12 mm. long, 8-ovulate; style slightly arcuate, sparsely pubes-
