Tree 10-20 m, 20-30 cm ø. Branchlets initially densely fulvous to rufous tomentose by adpressed stellate hairs, later glabrous, greyish, sparsely to densely lenticellate; terminal buds ovoid, 3-4 by 2-3 mm, scales narrowly ovate-acute. Stipules ovate to lanceolate, 3-5 by 1-3 mm. Leaves thin-coriaceous, (9½-)13-17(-21) by (3½-)4½-6 (7½) cm (index 2.3-3), broadest at or rarely above the middle; above glabrous, dull to glossy, greyish green to chocolate-brown, beneath with a thin cover of greyish to glaucous adpressed, minute stellate hairs, subglabrescent; base rounded-acute to attenuate-acute, top 1-2½ cm acuminate, tip sharp, oblique; midrib prominent beneath, slightly so above, rather broad especially near the base; nerves (9-)10(-11) pairs, thin, prominent beneath, flat above, subparallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation dense, subscalariform, obscure to distinct beneath; petiole 7-11 mm, 1-3 mm ø, adaxially flat. Inflorescence male or androgynous, densely yellowish brown to fulvous stellate hairy; bracts and bracteoles ovate-acute, ½-1 by ½ mm. Male rachis 10-20 cm, 2 mm ø; ♂ flowers in clusters of 3, filaments 3-4 mm, anthers 0.3 mm long, pistillode globose, 1 mm ø. Androgynous rachis 10 cm, 1½-2 mm ø; female flowers solitary, rarely in clusters of 2, staminodes well-developed but not exceeding the perianth, styles 3, conical, 1 mm, strongly recurved. Ripe cupule 1 cm stalked, cup-shaped, ⅔-1 cm long, 2-2⅓ cm ø; rim thin, covering ¼-⅓ part of the fruit; scales ovate, minute, adpressed, in more or less concentric rows, distinct on the upper half of the cupule only. Ripe fruit cylindrical or ovoid, 2-2⅔ cm long, 1⅔-2 cm ø, densely fulvous tomentose by adpressed, simple hairs, top rounded-acute, base rounded, scar strongly convex, 1-1½ cm ø; wall woody, 1-2 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
