(Shrub to) tree, up to 36 m high, dbh up to 1 m. Twigs 1-5 mm thick, glabrous. Leaves: petiole 0.4-7 cm long; petiolules 0.3-1.5 cm long; leaf axes glabrous. Leaflets elliptic, 4.5-18 by 1.75-10 cm, index 1.75-3.75, coriaceous, glabrous, (without or) with few to several glands; base acute to rounded, decurrent; apex (rounded to acute or) variably acuminate; the upper (to most) nerves ± distinctly joined; intersecondary veins variable; veinlets rather finely reticulate, prominulous at both sides, sometimes beneath more so than above. Inflorescences up to 20 cm long if solitary, no more than 5 cm if tufted; well developed axes with scattered side-branches, these patent and short or erec-to-patent and long; branches as well as the main axis (in its upper part) bearing several lax and often several-flowered cymes, the lower long-stalked, consisting of a central flower and two sometimes long and many-flowered monochasial branches, the upper sessile and monochasial, often, if the axis is short, together forming a dense cluster of branches and flowers; bracts deltoid to lanceolate, up to 1,5 mm long, sparsely hairy; pedicels 1.5-5 mm long. Flowers 5-merous. Sepals free, all about equal or the outer two distinctly smaller, ovate to obovate, especially the outer two concave, 1.6-2.8 by 1.4-2.5 mm, ciliate (to woolly-ciliate), glabrous or nearly so (in Sumatra exceptionally outside and sometimes also inside thinly puberulous). Petals obovate to spathulate, 1-3 by 0.5-1.2 mm, bigger in male than in female flowers, whitish, variably woolly. Disc uninterrupted or interrupted, yellow. Stamens (7 or) 8; filaments 2-5 mm long, woolly in the lower half to all over but 1 or the apex; anthers 0.6-0.9 mm long, gla-brous. Pedicels in fruit only slightly swollen, 1.5-2.5(-3.5) mm thick. Fruit lobe(s) globular to oblong-ellipsoid, 2.5-3.75 by 1.5-2.5 cm, densely aculeate, orange to pinkish; wall coriaceous, c. 0.5 mm thick.
