Tree 15-35 m, 30-45 cm ø; bark greyish brown, lenticellate. Branchlets initially with a dense cover of fulvous stellate hairs, soon glabrous, greyish black, sparsely lenticellate; terminal buds ovoid, 3 by 2 mm, scales ovate-acute. Stipules ovate-acute, 1-2 by 1 mm. Leaves coriaceous, 10-14 by 4-6 cm (index 2.2-2.6), broadest at or slightly below the middle; surfaces discolorous, above glabrous, greenish grey to dark chocolate-brown, dull, underneath with a thin cover of yellowish brown to fulvous adpressed, minute stellate hairs; base acute, top bluntly acute; midrib and nerves thin, flat on both sides; nerves 8-10 pairs, sub-parallel, at an angle of 45-50°, arcuating but not anastomosing towards the margin; reticulation fine, subscalariform to almost irregular, obscure; petiole glabrous, 6-10 mm, 1-2 mm ø, adaxially flat to furrowed. Inflorescence male or androgynous, densely fulvous woolly pubescent; bracts and bracteoles narrowly ovate-acute, 2-3 by 1 mm. Male rachis c. 5 cm, 1½ mm ø; ♂ flowers mostly solitary, filaments 3-4 mm, anthers 0.30-0.35 mm long, pistillode subglobose, c. 1 mm ø. Androgynous rachis 5-6 cm, 1-1½ mm ø; female flowers solitary or in clusters of 2-3, staminodes rudimentary, styles 3-4, terete, c. 1½ mm. Ripe cupule sessile to 1-1½ cm stalked, broadly cup-shaped, 1½-2 cm long, 4-4½ cm ø; rim thick, slightly incurved, covering ⅓-½ part of the fruit; wall woody, 3-5 mm thick, outside densely greyish brown tomentose by adpressed stellate hairs; scales obscure, ovate-acute, adpressed, imbricate but concentrically set. Ripe fruit depressed ovoid-globose, 2½-3 cm long, 3-4 cm ø, glabrous except the depressed-umbonate top, dark chocolate-brown, base rounded to conical, scar 2½-3 cm ø; wall woody, 5-7 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
