Tree 10-25 m, 30-40 cm ø; bark greyish brown, scaly. Branchlets initially densely fulvous to rufous scurfy tomentose by adpressed stellate hairs, later subglabrous, greyish to chocolate-brown, sparsely to densely lenticellate; terminal buds ovoid-ellipsoid, 2-6 by 2-3 mm, scales ovate to lanceolate. Stipules ovate to lanceolate, 3-6 by 2-4 mm. Leaves coriaceous, rigid, (6-)9-12(-14) by (2½-)3-4(-5) cm (index (1.8-)2-3(-3.6)), broadest at or above the middle; above glabrous, glossy, pale to dark chocolate-brown, underneath with a thick cover of fulvous to rufous adpressed stellate hairs; base acute to cuneate, decurrent, top rounded to abruptly acute; midrib strongly prominent beneath slightly so above; nerves (9-)10-11(-13) pairs, prominent beneath, impressed above, sut parallel, at an angle of 40-45°, arcuating and anastomosing near the margin; reticulation fine, subscalariform, lax, distinct beneath; petiole subglabrous, ½-1 cm, 1½-3 mm ø, adaxially flat. Inflorescence male, androgynous or mixed, densely fulvous stellate hairy; bract and bracteoles ovate, 1-1½ by ⅔ mm. Male rachis 7-15 cm, 1-2 mm ø, usually much-branched; ♂ flowers in clusters of 3-7, filaments 2-3 mm, anthers 0.35 mm long, pistillode globose, c. 1 mm ø. Androgynous or mixed rachis 5-10 cm, 1-2 mm ø; female flowers solitary or in clusters of 2-3, staminodes rudimentary, styles 3-6, terete, 1-1½ mm, recurved. Ripe cupule subsessile, cup-shaped, 1 cm long, 2-2.2 cm ø; rim thin, covering ¼-⅓ part of the fruit; wall woody, thin, inside densely dark chocolate-brown tomentose by adpressed stellate hairs, outside densely fulvous stellate hairy; lamellae 6-8, concentric, denticulate. Ripe fruit ovoid-conical, 1½-2 cm long, 1½-l.8 cm ø, glabrous, chocolate-brown, top abruptly acute, base truncate, scar flat, c. 1.1 cm ø; wall woody, thinner than 1 mm, for the greater part free from the cupule; cotyledons flat-convex.
