192 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, 
ovate-lanceolate, obtuse, hairy, about 6 mm. long, deciduous; calyx 3.7 to 4.6 
(4) mm. long, tubular, sparsely pubescent, the teeth broad, rounded, 1 to 2 mm. 
long; corolla 8.5 to 10 (9.2) mm. long, tubular, slightly broader at the apex, 
densely villosulous, the lobes acute, 2 to 3 mm. long; staminal tube included; 
style longer than the stamens, ending in a subpeltate stigma. 
Legume not known. 
Type in the John Donnell Smith Herbarium, collected near Popayfn, Cauca, 
Colombia, at an altitude of 1,700 meters, flowers, August 28, 1881, by F. C. 
Lehmann (no, 904). 
Perhaps nearly related to Inga densiflora Benth., from which it differs in 
having the leaves larger, broader, and thicker, the pubescence more abundant, 
the floral spikes longer, the flowers more numerous, etc. 
Inga stenopoda Pittier, sp. nov. PLATE 98. 
A tree; branchlets terete or subangulate, glabrous or very sparsely ferrugi- 
nous-hairy. 
Rachis of the leaves winged, sparsely ferruginous-hairy, 7 to 15 em. long, 
the petiolar part nude, terete, 1 to 2 cm. long, the wings about 7 mm. broad, 
attenuate toward the base, rounded at the apex; leaflets 5-jugate, petiolulate, 
subcoriaceous; glands subsessile, prominent, semiglobose, transversely com- 
pressed ; petiolules densely ferruginous-hairy, 2 to 8 mm. long; leaflet blades 
ovate-elliptic, more or less narrowed and rounded at the base, short-acuminate 
at the apex, glabrous and sublustrous above, rusty-colored and sparsely cov- 
ered with minute hairs beneath, the costa and veins more or less ferruginous- 
pubescent, slightly prominent above, strongly so beneath; blades of the basal 
pair 3.5 to 4.5 cm. long, 1.5 to 1.7 cm. broad, those of the terminal pair largest, 
7 to 10.5 em. long, 3 to 4.5 cm. broad. 
Floral spikes 2 to 4-clustered in the axils of the upper leaves or at the 
defoliate ends of the branchlets; peduncles minutely ferruginous-hairy, 1.5 to 
2.5 em. long; flower heads ovoid, the flowers sessile, the lower ones deciduous; 
bractlets ovate-oblong, pubescent without, about 6 mm. long, caducous; calyx 
tubular, striate, minutely pubescent, 5.38 to 5.6 (5.4) mm. long, the teeth long 
and acute; corolla tubular-campanulate, 11.8 to 12.6 (12.1) mm. long, silky- 
pubescent, the lobes ovate, acute, 2.5 to 38 mm. long; staminal tube included. 
Legume (specimen genuine?) entirely glabrous, long-pedicellate (3 cm.), 
rounded-cuneate at the base, the valves 1.1 cm. broad, the margin narrow and 
effaced. 
Type in the U. S. National Herbarium, no. 82668, collected at the junction of 
Rfo Beni and Rfo Madre de Dios, Bolivia, flowers (and fruits?), August, 1886, 
by H. H. Rusby (no. 995). 
The detached basal portion of the legume accompanying the specimen in the 
Field Museum Herbarium and described above may belong to another genus. 
The affinities of this species seem to be with Inga virescens Benth., which I 
have not seen.

A tree; branchlets subangulate, covered with numerous white lenticels, the 
younger parts ferruginous-pubescent. 
Rachis of the leaves ferruginous-pubescent, winged, 3.5 to 6 em. long, the 
wings 4 to 9 mm. broad, the petiolar part wingless, thickening toward the base,

pressed, pertuse; leatlets 3-jugate, petiolulate, suboblique, coriaceous; petiolules
