Tree, up to 25(-30) m high, dbh up to 30(-75) en, (with buttresses). Twigs 1.5-5.5 mm thick, variably densely short hairy, early glabrescent. Leaves: petiole 1-7 cm long; petiolules 1-12 mm long; leaf axes glabrous or thinly to densely brownish or ful-vous puberulous, glabrescent. Leaflets ± elliptic, up to 50 by 30 cm, index 1.5-2.5(-6.5), pergamen-taceous to coriaceous, glands few to many; base obcuse to acute; apex rounded to variably acuminate; nerves ending free but for the few uppermost on. 5s; intersecondary nerves not conspicuous; veins and veinlets finely to laxly reticulate, about equally raised on both sides to smooth (or slightly sunken) on the upper side. Inflorescences up to 25 cm long if solitary, much shorter if tufted; axes simple or with some short patent branches in the lower part, all branches bearing few to many sessile or subsessile, very condensed, few-to several-flowered cymes, towards the apex reduced to solitary flowers; bracts deltoid to lanceolate, up to 1.5 mm long, sparsely hairy; pedicels c. 2 mm long. Flowers 4-merous. Sepals free or slightly connate, the outer two usually slightly smaller than the inner ones, ovate to obovate, 1—2(—3) by 1-2.4 mm, outside and inside glabrous or hairy (nearly always inside at the base), ciliate. Petals obovate to broadly spathulate, 1-2.8 by 0.5-1.7 mm, short-to long-clawed with an ovate to transversely elliptic blade, variably woolly, nearly always with the exception of the base outside, inside often sparsely hairy to glabrous. Disc uninterrupted. Stamens 8 (9); filaments 1.5-2.5 mm long, woolly with the exception of base and apex to woolly in the upper half (to glabrous); anthers 0.3-0.8 mm long, glabrous or with a few hairs, (ciliate). Pedicels in fruit strongly swollen, (3.5-)5-7 mm thick. Fruit lobes ellipsoid to subglobular (or obovoid), 1.75-5 by 1.25-5 cm, aculeate or tuberculate (and/or colliculate to granulate), red or darkbrown; wall coriaceous, corky, or woody, 0.65-2.5 mm thick.
