Tree up to 22 m high, dbh up to 50 cm. Twigs terete, when young angular, 3.5-9 mm diam., light to purplish grey, early to late glabrescent. Leaves 5-9-jugate; petiole (sub)terete, mostly flattened at the base, 3-13.5 cm long by 1-4 mm thick; petiolules slightly grooved above, 2.5-8 mm long. Leaflets opposite to alternate, ovate (to elliptic), 3.5-18 by 1.5-7 cm, index 2-4, straight to falcate, (thin-)pergamentaceous, glabrous to sometimes sparsely hairy on the basal half of the midrib, usually small glands in some to most of the nerve axils beneath; base oblique to sometimes symmetrical, rounded to acute, attenuate; apex acute (to rounded); nerves 1-3 cm apart, widely to steeply spreading, variably curved, ending free; reticulation rather coarse (or dense beneath), beneath mostly more prominent than above. Inflorescences together pseudoterminal, up to 40 cm long, with few spreading branches, rather densely ferrugineous puberulous, ± glabrescent. Sepals ovate, 2-2.2 by 1.6-2 mm, outside densely, inside densely to sparsely hairy, not ciliate. Petals: claw c. 1 mm long, blade transverse-elliptic, in total 3-3.5 by 2-3 mm, claw and basal half of blade outside sparsely woolly, inside glabrous, inside with 2 scales. Stamens 8; filaments 6.5-7.5 mm long, in the lower half variably woolly; anthers 1.4-1.5 mm long, glabrous. Fruits globular to triangular-obovoid, 2-3 by 1.5-2 cm, stipe up to 1 cm long, usually apiculate, densely ferrugineous or fulvous puberulous to tomentose; wall 1-3 mm thick, fleshy, endocarp finely transversely wrinkled, sparsely (to densely woolly). Seeds 11-12.5 by 7-8 mm, black; hilum suborbicular to transverse-elliptic, 2-6 by 2-6 mm.
