Shrub to tree, 5-20 m high, dbh up to 45 cm; bark grey, thin. Branchlets usually sericeous when young; flowering twigs 3-10 mm thick. Leaves 2-4-jugate; rachis 4-21 cm long, terete, glabrous, petiole 2.6-7.3 cm long. Leaflets subsessile, opposite to alternate, elliptic, 6.3-19.2 by 2.5-7.1 cm, index 2.2-3, usually rather symmetrical, (acroscopic side broader), coriaceous, usually punctate; base attenuate; margin entire, flat; apex acute to cuspidate, often mucronulate; upper surface glabrous; lower surface duller, smooth, no papillae, glabrous (to sparsely sericeous), domatia absent or at least in some leaflets a single small sac on basiscopic side in axil of second nerve; venation on upper side flat (to raised), raised on lower; nerves 0.3-2.9 cm apart, usually marginally very indistinctly looped and joined, especially in the lower part of the leaflets; veins laxly reticulate, often distinct. Inflorescences axillary to ramiflorous, unbranched to branching basally and especially along the terete, sericeous, glabrescent, 3-13 cm long axis; first order branches up to 3.9 cm long; cymules cincin-nate, c. 2-flowered; bracts and bracteoles triangular, outside sericeous, inside glabrous; bracts 0.7-0.9 mm long; bracteoles 0.2-0.6 mm long; pedicels 3.3-5.5 mm long, sericeous. Flowers c. 3.2 mm in diam., sweet, faintly fragrant. Sepals 5, ovate, margin pilose, with glands, (outside sparsely pilose), inside glabrous; 2 outer smaller ones 1-1.7 by 1.2-2 mm; 3 inner larger ones 1.8-2.5 by 1.8-2.8 mm, margin petaloid. Petals 5, obovate, 1.8-1.9 by 0.6-0.9 mm, white; claw c. 0.4 mm high; margin pilose, apex acute, outside and inside sub-glabrous; scales c. 1 mm long, free; crest clavate, stipitate, apex lobed. Disc uninterrupted. Stamens 8; filaments 2.6-2.8 mm long, completely pilose, especially basally; anthers c. 0.5 mm long, glabrous. Pistil: ovary c. 0.3 mm long, subhirsute; style and stigma c. 0.1 mm long. Fruits with 1-3 well developed lobes, 1.3-1.6 by 1.6-3.3 cm, rough to slightly rugose or ribbed, glabrous, black when dry; stipe 1-1.5 mm high, slender; margin blunt; lobes 15-16 by 8-12.5 mm, broadly spreading; wall thin to rather thick, not exceeding 1 mm; septa complete. Seeds globose to obovoid, c. 10 by 7 mm; arillode without or with a small pseudo-funicle, but always with a basal rim; hilum c. 1.5 mm long.
