Tree c. 15 m, 40-50 cm ø; bark smooth. Branchlets initially densely fulvous tomentose by stellate hairs, later glabrous, sparsely lenticellate; terminal buds ovoid-globose, c. 3 by 2 mm, scales broadly ovate. Stipules linear to lanceolate, 8-10 by 2-3 mm. Leaves thick-coriaceous, (10-)12-14 (-15½) by 4-6 cm (index 2-3), broadest at or rarely above the middle; surfaces discolorous, above glabrous, glossy, dark brown, beneath densely silvery grey-tomentose by adpressed, stellate hairs; base acute, margin sometimes undulate, top acute to ½-1½ cm acuminate; midrib more or less prominent on both sides, dark brown; nerves 13-15 pairs, prominent beneath, obscure above, parallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation dense, scalariform, distinct beneath; petiole ½-1½ cm long, 2 mm ø, adaxially flat. Inflorescence male or androgynous, densely fulvous stellate-hairy; bracts and bracteoles ovate, 1-3 by 1 mm. Male rachis c. 10 cm, 1-1½ mm ø; ♂ flowers solitary or in clusters of 3, perianth 6-lobed, stamens 12, filaments 2-3 mm, anthers 0.3 mm long; pistillode subglobose, c. 1 mm ø. Androgynous rachis c. 10 cm, 1-2 mm ø; female flowers solitary, perianth 6-lobed, staminodes 12, rudimentary, styles 3-4, conical, 2-3 mm, recurved. Ripe cupule sessile to ½ cm stalked, ovoid, 2-2½ cm through; base truncate to concave, top acute; wall thinner than ½ mm, covering the fruit almost completely, densely yellowish brown to greyish tomentose; scales minute, adpressed, irregularly set; dehiscence irregular. Ripe fruit ovoid-conical, 1½ cm long, 2-2½ cm ø; wall bony, 1-1½ mm thick, densely yellowish brown tomentose, for the greater part free from the cupule; top acute, base rounded, scar flat to concave, c. 1 cm ø; cotyledons flat-convex.
