Tree 10-36 m, 10-120 cm ø; bark greyish brown, fissured to scaly, lenticellate. Branchlets initially strongly ribbed under the leaf-insertion, densely yellowish brown tomentose by adpressed stellate hairs, later terete, subglabrous, sparsely lenticellate; terminal buds ovoid, 2-4 by 2-3 mm, scales narrowly ovate-acute. Stipules ovate to linear-acute, 3-5 by 1-3 mm, soon caducous. Leaves thick-coriaceous, rigid, (10-)14-18(-24) by (4-)5-6(-8) cm (index 2-3), broadest at or above the middle; above glabrous, glossy chocolate-brown to olive-green, beneath densely yellowish brown to pale glaucous tomentose by adpressed stellate hairs; base acute to cuneate, decurrent, margin recurved, top abruptly acute to ½-1½ cm acuminate; midrib strongly prominent on both sides; nerves (12-) 14-15(-16) pairs, prominent beneath, impressed above, parallel, at an angle of c. 60°, arcuating but not anastomosing towards the margin; reticulation lax, fine, scalariform, distinct beneath; petiole 1-1½ cm, 1-2½ nun ø, shallowly furrowed. Inflorescence male, female or androgynous, densely yellowish brown stellate hairy; bracts and bracteoles narrowly ovate to linear, 2-2½ by 0.7-1 mm. Male rachis 10-20 cm, 1½-2 mm ø; ♂ flowers in clusters of 3, perianth 5-7-lobed, stamens 10-12, filaments 3-4 mm, anthers 0.30-0.35 mm long, pistillode subglobose, 1-1½ mm ø. Female or androgynous rachis 10-15 cm long, 2 mm ø; ♀ flowers solitary or in clusters of 3-5, staminodes rudimentary, styles 3, conical, 1-1½ mm, connate. Ripe cupule c. ½ cm stalked, cup-shaped, ½-1 cm long, 1½-2⅓ cm ø; rim thin, covering ¼-⅓ part of the fruit; wall woody, thin, inside densely fulvous tomentose by adpressed simple hairs, outside densely stellate hairy; lamellae 5-8, concentric, entire or denticulate. Ripe fruit depressed-ovoid, 1-1½ cm long, 1½-2 cm ø, densely pale greyish brown simple-tomentose, gla-brescent, top abruptly acute, base cordate, scar concave, c. 1 cm ø; wall bony, thinner than 1 mm, for the greater part free from the cupule.
