Tree to 15 m high with a rounded or spreading crown. Bark greyish, smooth or fissured; young branchlets sparingly pubescent when young but soon becoming glabrous. Leaves glabrous or subglabrous: petiole 2-7 cm long, a small rounded slightly raised gland usually present at or just below the junction of the lowest pinna pair; rhachis (0)2-8 cm long, sulcate above, a small rounded gland usually present at the junction of the top pinna pair, at the junction of each pinna pair or absent from some; pinnae (1)2-4 pairs; rhachillae 5.5-17 cm long, sulcate above, pulvinule sometimes sparsely pubescent; leaflets 4-9 pairs, 18-28 x 8-15 (18) mm, oblique basally, oblong to broadly elliptic or obovate, rounded to truncate apically, mucronate, margins crisped, glabrous to sparsely puberulous on both surfaces, petiolules often sparsely pubescent. Inflorescences globose; peduncles 1.5-4 cm long, sparingly rusty-pubescent. Flowers whitish, subsessile; bracteoles rapidly deciduous. Calyx 2.5-4 mm long, densely rusty-tomentellous. Corolla 4-6 mm long, lobes densely ± rusty-tomentellous, especially apically. Stamens 1-1.6 cm long, united basally for up to 6 mm, tube not or scarcely exserted beyond the corolla. Ovary 2-3 mm long, shortly stipitate, glabrous. Pods light brown, 8-21 x 1.4-2.6 cm, linear-oblong, valves thin, glabrous, not or scarcely venose, slightly umbonate over the seeds, longitudinally dehiscent.
Scarp forest, riverine thicket and open woodland, often along streams, usually along the upper altitudinal perimeter and on steep slopes.
