Large buttressed tree. Twigs, panicles, parts of perianth exposed in buds, stipules outside (subgla-brous to sparsely puberulent within), petioles, midribs above and leaf undersurface persistently ± densely shortly evenly pale ocherous buff to rufous pubescent; fruit sparsely persistently puberulent; leaf undersurface densely pale rufous lepidote (mature trees only). Twigs to 2 by 1.5 mm ø apically, +-compressed, smooth, becoming dark brown; stipule scars short, pale, transverse, with a prominent rib proceeding down the internode from the base. Buds to 3 by 2 mm, ovoid, subacute, compressed. Stipules to 15 by 4(-7 in young trees) mm, broadly or narrowly ovate, acute, subauriculate, not at first caducous. Leaves (4-)5-9(-10) by 2-4(-6) cm, ovate, elliptic or rarely obovate, ± coriaceous; base obtuse to subcordate; acumen to 8 mm long, narrow; nerves 13-18 pairs, slender, obscure above, at 50°-65°, arched near the margin; tertiary nerves densely scalariform, slender; midrib obscurely depressed above, terete and prominent beneath; petiole 5-7 mm long, short, slender. Panicles to 6 cm long, short, ribbed, terminal or axillary; branchlets usually bifurcate or fascicled, lax. Flower bud to 8 by 4 mm, ellipsoid. Sepals narrowly deltoid, subacute, the 3 outer somewhat narrower, longer than the inner 2. Petals white, pink at base within, broadly elliptic, obtuse. Stamens 15, shorter than the style at anthesis; filaments slender, tapering, as long as the slender lorate anthers; appendages to connectives very slender, 0.75-1 times length of anthers. Ovary ovoid, glabrous; style columnar, c. 3 times length of ovary, distinctly trifid at apex. Fruit pedicel to 2 by 2 mm. 3 longer calyx lobes to 11 by 2 cm, sublorate, obtuse, c. 5 mm broad above the to 12 by 10 mm saccate thickened base; 2 shorter lobes to 9 by 0.8 cm, linear, subacute, similar at base. Nut to 15 by 15 mm, ovoid, tapering to an up to 6 mm long slender style remnant.
