Tree, up to 40 m high, dbh up to 80 cm, sometimes with small buttresses, rarely a shrub. Twigs 2.5-15 mm in diam., tomentellous, tomentose, or velvety, mostly only late glabrescent. Leaves (1-) 2-9(-13)-jugate; petiole 2.5-21 cm long, 1-6 mm thick, terete to semiterete, in the latter case sometimes above with a longitudinal groove; axes mostly long remaining hairy; petiolules 2-7.5(-15) mm long, above variably grooved or sometimes flat, with or without a median rib. Leaflets (narrowly) elliptic, 6-35 by 1.75-12.5 cm, index 1.5-5, coriaceous or chartaceous, above glabrous to variably hairy along the midrib and on the lower nerves, rarely all over the surface, beneath variably hairy all over, between the nerves often minutely sericeous; domatia absent; base acute to broadly rounded, exceptionally subcordate, mostly variably attenuate; sides curved to straight and parallel; apex rounded to acute, mostly acuminate, the acumen up to 2.5 cm long, slender to sometimes broad, acute to sometimes obtuse; midrib above sunken to prominulous, nerves 0.5-2 cm apart, above prominulous to slightly grooved, intercalated veins variably developed, veins and veinlets either together closely or sometimes laxly reticulate, or the former ± clearly scalariform, at least the veinlets beneath often hardly visible. Inflorescences mostly in the upper leaf axils, together pseudoterminal, sometimes terminal, also rami-or cauliflorous, often long pendulous racemes or spikes. Sepals hardly to up to halfway connate, 1.1-2.5 mm long. Petal' mostly absent, if present often reduced in number. Disc hairy or glabrous. Stamens (4-)7 or 8 (or 9). Ovary 2-celled. Fruits ellipsoid to sometimes globular, 2-4 by 2-3 cm, glabrous or sometimes slightly hairy at the tip of the appendages, mostl y densely set with appendages, those filiform to narrowly strap-shaped and up to 2 cm long, or sometimes ligulate and 5-6 mm long, straight or often curved or curled, at base globular, pyramidal, or triangular and in the latter case often connate; wall coriaceous, thin.
More
A tree. It grows to 40 m high. The trunk can be 80 cm across. There can be small buttresses. The twigs are have a soft covering. The bark can flake off. The leaves have 1-13 leaflets on each side of the stalk. The leaf stalk is densely hairy. The leaflets are oval and they taper to the tip. The base is rounded. The leaves are 6-35 cm long by 2-12.5 cm wide. They are hairy underneath. The flowering cluster can be in the axils of the upper leaves or on the trunk. The long spikes can hang down. The fruit are oval or round and 2-4 cm long by 2-3 cm across. It is a variable plant with named varieties and sub-varieties.
Middle storey trees of the lowland primary rain forest, occasionally in secondary formations, largely confined to well-drained land on hills, ridges and slopes, on sandy, yellow sandy clay or clay soils; at elevations to 800 metres.

A tropical plant. It is an under-storey tree in the forest. It grows from sea level to 800 m above sea level. It needs well drained fertile soil.
Uses Locally cultivated as a fruit tree. The wood is sometimes used for constructions but is not of a very good quality. See Burkill, Dict. Econ. Prod. Malay Penins. (1935) 1544, 1548; Heyne, Nutt. Pl. Indon. ed. 3 (1950) 997.
