Tree 9-25 m, 15-40 cm ø; bark fissured to scaly, dark greyish brown to reddish brown. Branchlets initially densely yellowish brown to rufous-tomen-tose by adpressed, stellate hairs, later subglabrous, pale yellowish brown to dark greyish brown, fissured, sparsely lenticellate; terminal buds ovoid, 1-1½ by 1 mm, scales narrowly ovate-acute to lanceolate. Stipules lanceolate, 1-1½ by ⅓-½ mm. Leaves thick-coriaceous, rigid, strongly bul-late, (5-)7-9(-11) by (2½-)3-4(-5) cm (index 1.3-2.8), broadest at or slightly below the middle; above glabrous, glossy, olive-green, beneath densely pale grey-brown tomentose by adpressed stellate hairs; base acute, margin strongly recurved, top bluntly acute to ½-1 cm acuminate, rarely rounded-emarginate; midrib strongly prominent on both sides; nerves 9-10 pairs, strongly prominent beneath, impressed above, parallel, at an angle of 60-80°, arcuating but not anastomosing towards the margin; reticulation lax, subscalariform, obscure; petiole glabrous, 3-5 mm, 1-1½ mm ø, adaxially flat. Inflorescence male, female or mixed, densely yellowish brown stellate hairy; bracts and bracteoles ovate-acute, 1 by ½-⅔ mm. Male rachis 5-10 cm, 1-1½ mm ø; ♂ flowers solitary or in clusters of 3, filaments 2½-3½ mm, anthers 0.5-0.7 mm long, pistillode subglobose, c. 1 mm ø. Female or mixed rachis 5-10 cm, 2 mm ø; ♀ flowers solitary, staminodes rudimentary, styles 3-4, conical, 2-2½ mm, more or less connate. Ripe cupule subsessile, cup-shaped, ½-1 cm long, 1½-1⅔ cm ø; rim thin, covering ¼-⅓ part of the fruit; wall woody, inside densely yellowish brown to silvery tomentose by adpressed simple hairs, outside densely greyish brown stellate hairy; lamellae 5-8, concentric, minutely denticulate. Ripe fruit ovoid-conical, c. 1½ cm through, top abruptly acute, base rotundate, scar flat, 8-10 mm ø, glabrous, dark chocolate-brown; wall bony, c. 1 mm thick, for the greater part free from the cupule.
