Small tree. Branchlets initially densely greyish tomentose by adpressed, stellate hairs, later glabrous, dark greyish brown, sparsely lenticellate; terminal buds ovoid, c. 3 by 2 mm, scales ovate-acute. Stipules deltoid, c. 1 by ½ mm, soon caducous. Leaves thick-coriaceous, (8-)14-16(-18) by (3-)6-8 (-11) cm (index 1.8-2.2), broadest at or rarely above the middle; surfaces discolorous, above glabrous, glossy, chocolate-brown, underneath densely greyish brown tomentose by adpressed, stellate hairs; base rounded, sometimes asymmetrical, margin recurved, top bluntly acute to 1 cm acuminate; midrib and nerves strongly prominent beneath, flat to impressed above; nerves 11-14 pairs, subparallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation subscalariform, distinct beneath; petiole 1-2 cm, 2-3 mm ø, adaxially flat. Inflorescence male or female, densely pale yellowish brown stellate hairy; bract and bracteoles ovate-acute, 1½-3 by 1-2 mm. Male rachis 10-15 cm, 2 mm ø; ♂ flowers in clusters of 3, perianth 6-lobed, stamens 12, filaments 2-3 mm, anthers 0.3-0.35 mm ø, pistillode subglobose, 1½-2 mm ø. Female rachis 10-15 cm, 3-4 mm ø; ♀ flowers solitary or in clusters of 2-3, perianth 6-lobed, or occasionally irregularly lobed, staminodes 12, rudimentary, styles 4-6, conical, 1½-2 mm, connate. Ripe cupule solitary or in clusters of 2-3, sessile, ovoid-globose, c. 2 cm long, 2½ cm ø; wall thinner than 1 mm, covering the fruit almost completely except for an opening smaller than 1 cm ø, outside densely fulvous to greyish tomentose by stellate, adpressed hairs; lamellae 8-10, concentric or spiral, thin; dehiscence irregular. Ripe fruit depressed ovoid-globose, 1-1½ cm long, 2-2½ cm ø; top rounded, base rotundate, scar concave; wall 1-2 mm thick, woody, for the greater part free from the cupule, outside densely fulvous to rufous tomentose.
