Shrubs or treelets 1-6 m high, dbh 1.5-8 cm; bark smooth, finely striate, dark brown or black, underbark red, inner bark brown; wood reddish brown. Indumentum of young parts and inflorescences dense, brownish. Flowering twigs terete, 3-9 mm in diam., striate to grooved, thinly pilose to villose. Leaves 2-6(-10)-jugate; petiole 4.5-16.5 (-21.5) cm long, flattened above, rounded below, towards the apex terete; rachis 10-35.5(-45) cm long, terete; petiole and rachis striate, pilose to more or less villose; petiolules (0-)l-10(-20) mm long, iterete, rarely grooved above, more or less veluti-rous. Leaflets opposite to alternate, (narrowly) obovate to (narrowly) elliptic, slightly asymmetric, 6.5-35.5 by 2.5-12 cm, index 1.6-4.3, bright to dull, mid-to greyish or dark green above, paler green below, thinly to thickly papyraceous, above almost glabrous to thinly pilose, midrib and nerves more densely so, below (thinly) pilose, midrib and nerves usually more densely so; base cuneate to rounded; apex acuminate, sometimes acute, obtuse, or rounded, acumen 2—8(—15) mm long, usually mucronate; margin serrate, often only obscurely so in the lower part, rarely more or less dentate; midrib above slightly prominent to somewhat sunken, nerves 8-20 per side, at least the higher ones ending in a tooth, 4-27 mm apart, angle to midrib 50-80°; domatia, if present, obscure pocket-like. Inflorescences axillary, 1-3 cm long, in fruit up to 4.5 cm long, without or rarely with short branches, densely flowered, thinly pilose to ± villose; cymules 1-flowered; bracts and bracteoles triangular to deltoid, 1.2-3 by 0.7-1.8 mm, acute, thick, persisting, outside appressed-hairy, inside glabrous or with few hairs at the base; pedicels c. 1 mm, articulated at the base. Flower buds globular, 2.4-3 by 2.4-3 mm. Sepals broadly ovate to orbicular, persisting, concave, outside appressed-hairy except rim, margin ciliate, inside glabrous, outer 1.9-3.2 by 1.4-3.6 mm, scarious rim narrow to wide, inner 2.5-4.9 by 1.8-4.3 mm. Petals green, yellowish, or cream, ± elliptic to obovate, rarely (Kanis 1135, LAE 61135) with a distinct claw, irregularly dentate, 3-4.9 by 1.1-2.4 mm, outside glabrous or appressed-hairy in lower part, margin ciliate in lower part, inside glabrous or with few hairs in lower part; scales 2, not crested, 1.9-3 mm long, up to c. ⅔ adnate to the sides of the petal, woolly. Disc glabrous or with few scattered hairs to hairs in 5 tufts. Stamens 8, exserted; filaments 3-4.4 mm long, patently hairy; anthers 1.1-2 mm long, glabrous to hairy; in female flowers filaments 1.8-2.4 mm long, anthers 0.8-1.1 mm long. Ovary 3-celled, outside hairy; style 2.4 mm long; stigma 1.4 mm long, 3-lined; pistillode 1-1.2 by 1 mm. Fruits red to orange, inside yellowish, ellipsoid to obpyramidal, rounded triangular in cross section, 13-18 by 10-18 mm; wall 0.2-0.7 mm thick, outside smooth or rugose, villose, inside glabrous to thinly appressed-hairy. Seeds ellipsoid to globular, 10-14 by 6-10 mm, testa shiny black; arillode red to orange or golden brown, covering half to almost the whole seed, lacerate; cotyledons equal or unequal, collateral.
