Description:  "Young branchlets, leaf-rachi, inflorescences including the calyces and pods densely rusty pubescent with a short tomentose-villous indument; rachis wings rather prominent, the glands scarcely so; leaflets 3-5 pairs, oblong-elliptic, obliquely rounded at base, acuminate, finely reticulate, sparsely hirsutulous above, or the midnerve usually rusty-villous, hirsute-villous on the nerves and veins beneath, subcoriaceous, the larger terminal ones 1-2 dm. long, about 8 cm. broad; peduncles axillary, 4-11 cm. long, the spikes to 3 cm. long; bracts linear, shorter than the calyx, mostly persisting until after anthesis; calyx tubular, 8-10 mm. long with short acutish teeth; corolla densely sericeous-villous, 17 mm. long, or slightly longer, the stamen tube included; pods flat, 2 to several dm. long, about 2 cm. broad with dilated obscurely bisulcate margins. Becoming a large tree with spreading crown. (Macbride, 1943; 13(3/1)23-24).

"1-pinnately compound leaves with 3-4 pairs of leathery, tapering-elliptic leaflets arranged oppositely along a winged axis (central stem).  The white, mimosa-type, 1.25-1.5-inch long flowers are borne in heads at the apeses of brownish-fuzzy stalks.  The green pods are flattened, 8-24 inches long and 2-3 inches wide, and 4-angled by virtue of their distinctly raised margins  (Staples & Herbst, 2005; p. 332).

Habitat/ecology:  "Daylength: Pacay is apparently daylength neutral, at least within the subtropics, which in any case are its outer limits.

Rainfall: Pacay requires a subtropical climate with plenty of moisture. At Yurimaguas (Peruvian Amazon), both I. feuillei and I. edulis are very productive (wood, leaf, and fruit) at 1,500-2,700 mm annual rainfall.

Propagation:  Seed

Native range:  Bolivia and Peru; widely cultivated in South America (Staples & Herbst, 2005; p. 332).
