Small tree, up to 6 m high, dbh up to 12 cm, not or hardly branching; puberulous, early glabrescent. Twigs 4-9 mm in diam., usually grooved. Leaves (2-or) 3-5-jugate; petiole 7-17 cm long; petiolules 8-15 mm long. Leaflets ovate to obovate, 5-26 by 2-10 cm, index 2-4.5, pergamentaceous to subcoriaceous; base acute (to obtuse); domatia absent or inconspicuously in the axils of the nerves below; midrib above prominent, angular; nerves 7-13 per side, moderately curved; nerves and veins prominent on both surfaces. Inflorescences ramiflorous on up to 15 mm thick branches consisting of 1-7, up to 10 cm long axes, simple (or sparsely branched at the base); bracts triangular, up to 1 mm long. Calyx lobes hardly connate, triangular to ovate, 1.5-2.5 by 1-2 mm, membranous with 1 or 3 visible nerves, outside sparsely pubescent, inside glabrous or with a few hairs near the base. Petals (2-)5, elliptic, c. 1.5 by 1 mm, sparsely accrescent to 3 by 2 mm in young fruits, not clawed, glabrous; auricles usually present, sparsely pubescent. Disc annular, usually with lobes protruding between the stamens, ± confluent with the base of the fruit, 1.5-2 mm in diam., glabrous. Stamens 8, 3-4 mm long; filaments glabrous to sparsely puberulous; anthers papillate, glabrous. Pistil hardly stipitate, distinctly triangular, hairy. Fruits up to 3 cm high, glabrous; stipe 4-12 mm high, triangular in cross section; seed-bearing part ellipsoid to obovoid, triangular (or rounded-triangular) in cross section, up to 1.2 cm in diam., apiculate for 1-3 mm, inside glabrous; endocarp thin, (nearly) completely sclerenchymatic. Seeds ellipsoid, up to 1.2 cm long; cotyledons subcollateral, both folded, the lower usually smaller than the upper.
