Tree 15-20 m, 30-90 cm ø. Branchlets initially densely yellowish brown to fulvous tomentose by woolly stellate hairs, later glabrous, greyish brown, sparsely to densely lenticellate; terminal buds ellipsoid, 5-8 by 2-3 mm, scales linear-acute to lanceolate, densely yellowish brown erect stellate hairy. Stipules linear-acute, 5-6 by 1-2 mm. Leaves thick-coriaceous, rigid, (10-)14-16(-20) by 3-6 cm (index (2½-)3(-5)), broadest at or rarely below the middle; surfaces concolorous, glabrous, pale greyish green, dull beneath, glossy above; base acute, top bluntly acute to rounded, rarely 1-2 cm acuminate; midrib strongly prominent on both sides; nerves 8-10 pairs, thin, prominent beneath, impressed above, subparallel, at an angle of 45-50°, arcuating but not anastomosing towards the margin; reticulation fine, subscalariform to irregular, obscure; petiole 10-13 mm, 2 mm ø, adaxially flat, towards the base gradually thickened and corky. Inflorescence male, androgynous or mixed, densely yellowish brown tomentose by adpressed stellate hairs; bracts and bracteoles ovate, 2-3 by 1 mm. Male rachis 10-25 cm, 1-1½ mm ø; ♂ flowers in clusters of 2-3, filaments 3-5 mm, anthers 0.3 mm long, pistillode subglobose, occasionally compressed, c. 1 mm ø. Androgynous or mixed rachis 10-20 cm, 2 mm ø; female flowers solitary or rarely in clusters of 2, staminodes rudimentary, styles 3, conical, 2 mm, recurved. Ripe cupule sessile, saucer-shaped, ½-1 cm long, 2½-3 cm ø; rim thin, incurved, covering the basal part of the fruit; wall woody, 1-2 mm thick, inside densely greyish brown tomentose by adpressed simple hairs, outside densely fulvous stellate hairy; scales subulate, 3-4 mm long, free, recurved or patent, densely but irregular set. Ripe fruit subglobose to cylindrical, 2½-4 cm long, 2-2¾ cm ø, glabrous, dark chocolate-brown, top rounded umbonate or rounded-acute, base rotundate or cordate, scar deeply concave, 1-1½ cm ø; wall woody, 2 mm thick, for the greater part free from the cupule.
