Shrub, treelet or small tree to 10 m high. Branchlets terete, minutely puberulous or glabrous. Stipules linear, falcate, acute, (0.8-)2-3.5 cm, minutely puberulous, late caducous. Leaves: rachis (8-) 15-30 cm, glabrous or minutely puberulous; gland obscure, circular, pit-like, without raised margins, 0.8-2 mm in diameter; pinnae 1 pair, 15-39(-50) cm, glabrous or minutely puberulous; with glands similar to the rachis-gland, 0.5-1 mm in diameter; petiolules 5-7 mm, glabrous or minutely puberulous; leaflets 2½-6½ pairs per pinna, the lower leaflet often unpaired; leaflets opposite, rigidly chartaceous, drying brownish, grey or green, ± equal-sided, ovate-elliptic, elliptic, or lanceolate to oblong, 6-25(-30) by 3.1-9.5 cm, base ± symmetrically cuneate or rounded, apex acuminate(-caudate), both surfaces glabrous or minutely puberulous, occasionally very minutely glandular haired; principal lateral veins 5-7(-10) per leaflet-half, arching, non-parallel; reticulation prominulous or prominent above, prominent beneath. Inflorescences on the older wood, rarely at the leaf-axils, consisting of unbranched, shortly pedunculate racemes issuing from short-shoots at the axils of old leaf-scars; raceme (1.5-)2.5-10 (-13) cm, glabrous or scarcely puberulous, floral bracts ovate or falcate-filiform, 2-3 mm, pedicels 1.5-5 mm, glabrous. Flowers usually pentamerous, male or female, or rarely bisexual. Calyx olivaceous or yellowish green, campanulate, 2.5-6 mm, often with 2 incisions up to 2 mm deep, glabrous; teeth inconspicuous. Corolla creamy white or greenish, funnel-shaped, 13-22 mm, glabrous; lobes ovate-lanceolate to oblong, acute, 4-10 mm. Stamens white to light yellow, 30-45 mm, tube shorter than or longer than the corolla-tube. Ovaries 4-8(-14), sessile, glabrous. Pod red outside, orange within, curved into a ± semicircle, 7-17 by 1.5-2 cm, fleshy, with slightly or strongly sinuous dorsal margin, sometimes moniliform due to abortion of some seeds, glabrous, veins invisible, pod dehiscing first along the dorsal suture. Seeds bluish or black, ellipsoid, c. 10-14 by 6-8 by 5-7 mm.
