Legume not known. 
Type in the John Donnell Smith Herbarium, collected at El Guarda Viejo, 
near Guatemala City, Guatemala, at an altitude of about 1,670 meters, flowers, 
February, 1890, by John Donnell Smith (no. 2316). 
The general affinities of this species are with Inga spuria Willd., but it differs 
in its abundant pubescence and 7-jugate leaflets, and in having the floral spikes 
always single in the axils of the leaves and the ovary villous at the base. 
Inga eriocarpa Benth. Lond. Journ. Bot. 4: 615. 1845. 
Branchlets subangulate, the younger parts, the rachis of the leaves, and the 
inflorescences densely fuliginous or brown-hairy. 
Rachis of the leaves broadly winged, 10 to 12.5 cm. long, the petiolar part 
mostly nude, 1 to 2 cm. long; leaflets 5-jugate, rarely 4 or 6-jugate, subsessile, 
coriaceous; glands rather large, sessile, concave, darkish; leaflet blades sub- 
oblique, ovate, rounded or subemarginate at the base, subacute at the apex, 
glabrescent or sparsely appressed-hairy above, the costa densely fulvous-hairy, 
beneath softly hairy and subreticulate, the costa and veins strongly prominent, 
the blades of the basal pair 1.5 to 4 cm. long, 0.7 to 1.5 cm. broad, those of the 
terminal pair 7 to 8.5 cm. long, 3 to 3.5 cm. broad. 
Inflorescences paniculate at the ends of the branchlets, sometimes sessile, but 
usually on peduncles 1.5 to 2.5 cm. long from base to insertion of the first 
flower; flower heads elongate, the lower flowers deciduous, the rachis up to 6 
cm. long; flowers sessile; bractlets ovate, fulvous-hairy without, about 8 mm. 
long, caducous; calyx turbinate, thickly fulvous-hairy without, 13 to 14 (13.4) 
mm. long, the teeth acute, 4 to 6.5 mm. long; corolla tubular, the upper half 
broadened, silky-villous, 20.8 to 21.7 (21.1) mm. long, the lobes ovate, subobtuse, 
5 to 5.5 mm. long; staminal tube almost equaling the corolla, the stamens 7 to 
8 cm. long; pistil about 8 cm. long, the ovary short (4 mm.), sessile, 20-ovulate, 
the style capitellate. 
Legume (fide Bentham) subterete, suleate, densely tomentose.
