Large buttressed tree. Buds, stipules outside, panicles, parts of petals exposed in bud and ovary shortly densely evenly persistently buff pubescent; sepals thus at first, becoming sparsely so; twigs, petioles, midribs above and nervation beneath caducously so. Twigs c. 3 mm ø apically, ribbed, becoming terete, smooth, blackish. Buds to 5 by 3 mm, ellipsoid, obtuse. Stipules to 14 by 6 mm, oblong, obtuse, caducous. Leaves 7-20 by 4-10 cm, ovate to obovate, thinly coriaceous; base broadly cuneate to cordate; apex acute or with up to 1 cm long, slender acumen; nerves 9-14 pairs, slender but prominent beneath, at 90° at the base, down to 45° towards the apex; tertiary nerves densely scalariform, slender, obscure; midrib prominent, terete, beneath, evident but ± applanate above; petiole 15-33 mm long, geniculate. Panicle to 5 cm long, terete, terminal or axillary, singly branched; bracts and bracteoles and mature flowers unknown. Sepals broadly ovate, sub-equal; stamens c. 20; filaments compressed, tapering; anthers oblong; appendages exceeding anthers, setose; ovary narrowly ovoid; style short, glabrous. Fruit pedicel to 1 by 1 mm, short. 3 longer fruit calyx lobes to 9 by 1.8 cm, spatulate, obtuse, c. 6 mm wide above the to 13 by 10 mm ovate saccate thickened base; 2 shorter lobes to 6 by 0.4 mm, lorate, obtuse, otherwise similar. Nut to 1.8 by 1.4 cm, ovoid, crowned by an up to 3 mm tapering style remnant.
