Understorey tree up to 11 m tall and 20 cm dbh. Stipules ca. 3.5 mm long. Leaves alternate, simple, penni-veined, glabrous. Flowers ca. 4 mm diameter, white-yellowish, placed in axillary bundles. Fruits ca. 5 mm long, pinkish-red, dehiscent capsules, seeds with orange aril.

Shrubs to treelets up to 5(-15) m high, dbh up to 20 cm; flowering twigs 1-2 mm thick; glabrous to hirsute all over. Leaves red when young; stipules deltoid, 3-4 by 0.8-2.2 mm, acuminate, very stiff, late caducous; petiole 1.5-3 mm long; blade (ovate to) elliptic, 2.4-9.6(-13.7) by 1-3.8(-4.8) cm, length/width ratio 1.4-2.8, chartaceous, base symmetric to asymmetric, attenuate to cuneate, margin flat, apex bluntly acuminate to sharply cuspidate, mucronate or not, upper surface (sub)glabrous, (dark) green, lower surface glabrous to hirsute, pale light green, venation flat above, slightly raised underneath, indistinct, nerves 8-10 per side, veins scalariformly reticulate. Inflorescences fascicles with a few staminate and/or pistillate flowers, usually less than 5 (to up to c. 10), staminate flowers occasionally in short (less than 1 cm) racemes. Flowers greenish to (yellowish) whitish; sepals 6, free. Staminate flowers 3.5-4.2 mm in diameter, pedicel 3.5-12 mm long, glabrous to hirsute; sepals elliptic to obovate, outer ones 2.1-2.5 by 0.9-1.2 mm, inner ones 2.1-2.2 by 0.8-1 mm; stamens 3, androecium 0.8-1.3 mm long, anthers 0.6-0.9 mm long, light yellow to grey, connective teeth 0.2-0.3 mm long. Pistillate flowers 1.5-1.7(-3) mm in diameter; pedicel absent to up to 4 mm in fruit; sepals triangular (to elliptic), outer ones 0.8-1.6 by 0.4-0.9 mm, inner ones 1-1.7 by 0.3-0.8 mm; ovary 3(-5)-locular, 0.9-1.5 by 0.5-1 mm high; stigmas 2.2-2.6 mm long, united except for upper third, free parts acute, sometimes constriction beneath stigmas. Fruits lobed around seeds (to around locules), circular, flattened, (slightly) depressed above in centre, 7.5-9 by 4-5 mm high, red, sutures indistinct, always hairy, glabrescent; wall thin; column 2.5-3 by 1.5-2 mm, only narrow basal triangle left. Seeds 3.8-4 by 3.3-3.8 by c. 2.5 mm, orange to red. [from Flora Malesiana]
