Tree to 16 m high and 15( — 35) cm in diam. Stipules intrapetiolar, 3.5-4.5 mm long. Leaves (1-or) 2-(or 3-)foliolate (usually one leaflet early shed and two persistent), shortly petioled; petiole and rachis 0.5-2.5 cm long. Leaflets chartaceous, subcoriaceous or coriaceous, obovate-or elliptic-oblong, or oblanceolate, 12-24 by 4-6.5(-9) cm; apex acute, abruptly or gradually, shortly acuminate, sometimes rounded to subemarginate; base acute, obtuse or rotund, often symmetric; glabrous above, minutely, loosely, ap-pressedly puberulous, glabrescent (or almost glabrous except on the midrib) beneath; nerves 5-7 per side; petiolules 1.5-5 mm, glabrous. Inflorescences axillary, up to 45 cm long, pendulous, the rachis puberulous, rather densely flowered; bracts 2-3.5 mm long, ovate or triangular, or 3-lobed at about the upper 1/3 (the middle lobe redivided into a 3-pointed fork), puberulous, glabrescent, often minutely ciliate on the margin; bracteoles 2, opposite, small, ovate or triangular, 0.35-0.75 mm long, puberulous on both surfaces, glabrescent, usually persistent; pedicels 1-2 mm, articulated at the apex, puberulous. Flowers white, yellowish white, or pale green, loosely puberulous outside, glabrescent, glabrous inside. Hypanthium shortly cupular, c. 1.5 mm long. Calyx lobes elliptic or ovate, 3-4 by 1.5-2 mm. Stamens 8-10; filaments up to c. 12 mm, glabrous; anthers ellipsoid, 0.75 mm long. Pistil stipitate; stipe c. 1 mm long, free, glabrous; ovary c. 3 mm long, 3-5-ovuled; style 6-8 mm, glabrous, recurved; stigma minute, round, discoid. Pods oblong, ovate or broadly elliptic, 4-9 by 2-4 cm long, rugose, slightly beaked, dehiscing into 2 crooked, rather thin valves, 1-4-seeded.
