Slender, much branched, bushy trees, sometimes shrubs, up to 15(-25) m high, dbh up to 20(-30) cm; bark grey to brown, or grey-brown blotched, smooth, rarely underbark red and green with finely anastomosing streaks; inner bark greenish, pinkish, reddish or (pale)brown; wood pinkish or pale straw, sometimes white, heartwood pinkish straw, pale red, pinkish, or ginger. Twigs 1.5-4 mm thick. Leaves 3-9(-12)-jugate; petiole up to 1.5(-2.5) cm long; rachis 1.5-16 cm long, marginate to narrowly winged; petiolules 0-2 mm long. Leaflets elliptic to ovate, (very) shiny, light to dark green, below often paler than above, reddish or purplish green when young, (0.6-)2-9(-12.5) by (0.4-)l-2.5(-3.5) cm, index (1.7-)2-3.5(-4.5), oblique, (thin-)pergamentaceous, above mostly short-hairy, sparsely to densely so on midrib (and nerves), veins, margin, and axils sometimes sparsely so, beneath short-or long-hairy, midrib and sometimes nerves, veins, and nerve axils sparsely to densely so; apex obtuse to acute, rarely very short acuminate, very apex obtuse to retuse; nerves (2.5-)5-13(-19) mm apart; domatia usually present and well developed. Inflorescences simple or sometimes sparingly branched, often only at the base; bracts and bracte-oles up to 1.5 mm long; pedicels up to 1.5 mm long. Flowers white to yellow, 3-4(-5) mm in diam. Sepals 1.2-2 by 0.8-1.6 mm, the inner-or outermost (or both) sometimes smaller, outside sparsely to densely hairy, inside glabrous to sparsely hairy. Disc 1-1.5 mm in diam. Stamens: filaments with long-patent hairs, sometimes sparsely short-hairy, in male flowers (1.4-) 1.8-2.6 mm long, in female flowers 0.6-1 mm long; anthers cordate to broadly ovate, 0.4-0.8 by 0.5-0.8 mm, glabrous. Ovary ovoid to ellipsoid, 2-(or 3-)celled, 1.1-1.8 by 0.7-1.4 mm, densely hairy, (very) sparsely scaly; style 0.6-1.2 mm long; pistillode 0.3-0.6(-l) mm long. Fruits somewhat fleshy, from brown green through orange(-yellow) to orange-red, finally orange-brown, subglobular to transversely ellipsoid, 6-8 (-12) by 6-8(-l 1) mm, 1-or 2-(or 3-)seeded, outside sparsely or sometimes densely hairy, (very) sparsely scaly, inside glabrous or with a few hairs near the placenta. Seeds ovoid to ellipsoid, rarely flattened, 4-9 by 4-7 mm, testa black, shining, more or less hard shell, sarcotesta (light) orange or yellow, covering (45-)60-100% of the seed, dorsally interrupted by a very narrow to very wide cuneate cleft; upper cotyledon slightly larger than the lower one.

Usually found along creeks and rivers, in rainforest.

Uses Often used as an ornamental tree because of its orange fruits and reddish young leaves (Vim Royen 1964: 4). The wood is used for house posts.
