Tree 25 m high. Stipules more or less intrapetiolar, triangular to lanceolate, up to 7 (-13) mm long. Leaves (4-)6-8-foliolate, shortly petioled; petiole and rachis up to 10 cm long, ending in a subulate tip (up to 10 mm long), rusty tomentose. Leaflets chartaceous or subcoriaceous, elliptic-oblong or obovate-oblong, 7-9(-15) by 2-3(-4) cm; apex acuminate or caudate; base obtuse, rounded, or cuneate, symmetric; glossy, glabrous above, rusty pubescent (often dense on the midrib) beneath; nerves 5-8 per side; petiolules very short, 1-2 mm, pubescent. Inflorescences axillary or terminal, usually erect, up to c. 15 cm long, the rachis rusty tomentose, rather densely flowered; bracts ovate to lanceolate, sometimes oblanceolate, (5-)7-9 mm long, pubescent outside and glabrous inside, some of them 3-lobed and the central lobe imparipinnately relobed; bracteoles lanceolate or spoon-shaped, 6-9 mm long, almost enclosing the bud; pedicels 10-15 mm, pubescent, articulated at the apex. Flowers pubescent outside. Hypanthium 2-2.5 mm long. Calyx lobes 4 (sometimes with 1 or 2 additional, smaller, glabrous ones), ovate, unequally sized, 5-7 by 3.5-5 mm, glabrous inside. Stamens 10, or rarely 9; filaments unequal in length, up to c. 15 mm; anthers 0.75 mm long. Pistil shortly stipitate; stipe c. 2 mm long, free, glabrous; ovary c. 3 mm long, (4-)6-ovuled; style 8-17 mm, glabrous or slightly hairy at the basal part; stigma slightly thicker than the style. Pods (unripe) elliptic, ovate-oblong, or obovate, 7-10 by 2.5-3.5 cm, flat, cuneate at both ends, rusty, velvety, valves thinly leathery, usually 1-seeded. Seeds shortly oblong, broadly elliptic, or rounded, flat, 3-4 by 2-3 cm.
