Shrub or tree up to 15(—25) m high; puberulous on all young parts and especially in the inflorescences, brownish ferrugineous, partly glabrescent. Twigs (2-)3-9(-12) mm in diam., brownish to reddish brown, (becoming greyish brown). Leaves (l-)2-5(-6)-jugate; petiole 3-25 cm long; petiolules 3-12 mm long. Leaflets ovate to elliptic, (5-) 7-20(-40) by (l-)2-6(-15) cm, index 2-5(-8), pergamentaceous to coriaceous; base rounded or angular; domatia usually present in the axils of the nerves below; midrib above prominent, angular (to rounded in the basal part or completely so), rather flat and broad in the basal part in big leaflets; nerves (6-)9-20(-25) per side, at least prominent on the lower surface, (hardly distinct from veins); veins usually coarsely reticulate, above hardly or not prominent, beneath prominent. Inflorescences axillary and pseudoterminal; main axis up to 40 cm long; secondary axes 1-20 cm long; cymules up to 11 mm long; bracts triangular, up to 6 by 1.5 mm (to 8 by 4 mm), (those of the secondary axes caducous). Calyx hardly connate, rarely so for ¼; lobes triangular to ovate, 0.75-2 by 1-2 mm, subcoria-ceous to slightly fleshy, sometimes l(-3) nerves visible, outside puberulous to pubescent (to very sparsely so in the upper part), inside puberulous, at least at the base as a more or less dense row. Petals 0-5, usually unequal, ovate to elliptic, minute to 2 by 1 mm, glabrous or pubescent (usually at the base), not clawed, usually auriculate. Disc annular, (1 —) 1.5—2(—3) mm in diam., sometimes irregularly lobed, rarely with lobes protruding between the stamens, puberulous or glabrous. Stamens 7 or 8, 3-4 mm long; filaments puberulous (to glabrous); anthers papillate, sparsely pubescent or glabrous. Pistil puberulous. Fruits (0.8-)l-2(-3) cm long, glabrous; stipe 2-11 by 1-2 mm; seed-bearing part globose to ellipsoid to obovoid, triangular (or triquetrous) in cross section, 0.4-1.4 cm in diam., inside glabrous (or completely, rather densely hairy); endocarp incomplete (2 mm thick at either side of the suture) to complete, usually less so in the fertile than in the sterile cells. Seeds up to 8(—12) mm long, ellipsoid to globose; cotyledons subcollateral, both or only the lower one folded, lower one usually smaller.

Trees, evergreen, 4-10 m tall or more. Branches brownish red when dry, strong, stout, only pubescent when young. Leaves with petiole 20-45 cm, axis striate, petioles inflated at base; leaflets (2 or)3-5-jugate; petiolules 8-10 mm; blades dull when dry, lanceolate or oblong-lanceolate to oblong, 10-25 × 2.5-7.5 cm, papery or thinly leathery, glabrous, reticulate veins visible, slightly prominent, lateral veins 10-15 pairs, slightly curved, base broadly cuneate to subrounded, apex acuminate or shortly acuminate, mucronate. Inflorescences often multibranched, rarely racemose, solitary and axillary or several fascicled near branch apices, nearly as long as leaves or longer, main rachis and branches ± hairy. Pedicels 2-5 mm. Sepals triangular-ovate, ca. 1.5 mm, both surfaces pilose. Petals 1-5 or absent, lanceolate or scalelike. Disk hirsute. Filaments unequal in length, 2-3 mm, pilose. Capsules pear-shaped or clavate, 1.2-2.5 cm, part bearing seed 7-10 mm in diam., usually 1-loculed, with 1 seed. Fl. spring, fr. summer.
A shrub or small tree. It can be 25 m tall. The leaves are alternate and compound. The leaves have 2-12 leaflets. The flowering shoots are 40 cm long. The flowers are 5 mm across. The fruit are 1-2 cm long and 3 cm across. They are red. There is an orange fleshy layer around the seeds.
A mid-canopy tree in both primary and secondary forest, growing in mixed dipterocarp, coastal (mangrove edges, beach edges), and sub-montane forests, both on slopes and ridges as well as by rivers and streams; at elevations up to 2,000 metres.
