Large buttressed tree. Midrib and nerves above, branchlets of panicle, bracteoles, ovary and parts of petals exposed in bud +-densely persistently cream puberulent; calyx at first so, becoming sparse, glabrescent; twigs, buds, bracts, stipules, petioles and nervation beneath +-sparsely persistently scabrid pubescent. Twig 2-3 cm ø apically, rather stout, ribbed, becoming terete, smooth; stipule scars pale, distinct, amplexicaul. Bud to 15 by 10 mm, ovate, acute, compressed. Stipules to 1.5 by 11 mm, ovate-auricu-late, prominent, not at first caducous. Leaves 12-24 by 8-11 cm, large, oblong, thinly coriaceous; base ± shallowly cordate or sometimes obtuse; apex obtuse or to 2 cm long slender acuminate (young trees); nerves 14-19 pairs, prominent beneath, ± depressed above as also the midrib and tertiary nerves, set at c. 45° towards the apex, at c. 90° at the base, usually with short less prominent secondary nerves; tertiary nerves remotely scalariform; petiole 1.5 to 2.5 cm long, rather stout. Panicles to 25 cm long, terminal or subterminal axillary, stout, spreading, many-flowered, singly (if axillary) or doubly branched; branchlets to 3 cm long, bearing to 8 flowers; bracts as stipules but somewhat smaller, bracteoles to 6 by 3 mm, elliptic, subacute, neither at first caducous. Flower bud to 6 by 3 mm, fusiform. Sepals narrowly ovate; outer 3 acute, inner 2 slightly shorter, prominently acuminate. Stamens 15, unequal, slightly shorter than style at anthesis; filaments broadly compressed at base, abruptly tapering and filiform distally; appendages slender, glabrous, 3-4 x length of the subglobose anthers. Ovary and stylopodium pyriform, densely pubescent; style somewhat shorter, filiform, glabrous. Fruit pedicel to 2 mm long, stout; 3 longer calyx lobes to 12(-17) by 1.5 cm, spatulate, coriaceous, obtuse, c. 6 mm broad above the to 12 by 10 mm ovate saccate thickened base; 2 shorter lobes to 3.5 by 0.3 cm, linear, similar at base; nut to 23 by 14 mm, ovoid, acute.

Widespread, often abundant, in lowland, evergreen, mixed Dipterocarp forest on fertile well-drained soils; at elevations below 300 metres.

Can be grown by seedlings. Seeds needs soaking.
