Tree 10-24 m, 25-65 cm ø; bark smooth, grey, lenticellate. Branchlets initially densely fulvous-tomentose with adpressed stellate hairs, later sub-glabrous, greyish to blackish brown, sparsely to densely lenticellate; terminal buds ovoid, 3-4 by 2-2½ mm, scales narrowly ovate-acute to linear, 2½-3 by 0.7-1 mm. Stipules linear-acute, 3-4 by 1 mm. Leaves thin-coriaceous, (8-) 10-13 (-16) by 4-5 cm (index 2.4-3.4), broadest at the middle; surfaces discolorous, above glabrous, pale greyish green, beneath densely greyish to yellowish brown tomentose by adpressed stellate hairs; base acute, margin recurved, top bluntly acute to 1-2 cm acuminate; midrib prominent on both sides; nerves (7-)8-10(-12) pairs, more or less prominent beneath, subparallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation lax, fine, subscalariform, distinct beneath; petiole glabrous, 1-1.2 cm, 1 mm ø, furrowed. Inflorescence male or androgynous, densely greyish brown stellate hairy; bracts and bracteoles narrowly ovate to linear, 1-2 by ½ mm. Male rachis 10-15 cm, 1-1½ mm ø; ♂ flowers in clusters of 3, rarely solitary, perianth 5-6-lobed, stamens 10-12, filaments 2½-3 mm, anthers 0.25-0.30 mm long, pistillode subglobose, c. 1 mm ø. Androgynous rachis 10-15 cm, 1-2 mm ø; female flowers solitary, rarely in clusters of 3, staminodes rudimentary, styles 3-4, conical, c. 1 mm, connate. Ripe cupule sessile, obconical, cup-shaped, 1-1½ cm long, 2-2½ cm ø; rim thin, covering the basal part of the fruit; wall woody, inside densely silvery grey tomentose by adpressed simple hairs, outside densely fulvous to greyish stellate hairy; lamellae 8-10, rounded, prominent, concentric. Ripe fruit ovoid-conical, 2-3 cm long, 1.8-2.5 cm ø, densely fulvous tomentose by simple adpressed hairs, top abruptly acute, base rotundate, scar flat to convex, 1-1½ cm ø; wall bony, c. 1 mm thick, for the greater part free from the cupule.
