Tree 20 m, 60-70 cm ø; bark greyish brown. Branchlets initially densely yellowish brown stellate hairy, later glabrous, greyish, sparsely to densely lenticellate; terminal buds ovoid, 0.7-1 by 1½-2 mm, scale narrowly ovate. Leaves thin-coriaceous, (8-)12-17(-20) by (4-)5-6(-8) cm (index 2-3), broadest at or slightly above the middle; above glabrous, dull to glossy, greyish green to chocolate-brown, beneath densely greyish tomentose by adpressed stellate hairs; base acute, margin recurved, top abruptly acute to 1-3 cm acuminate; midrib strongly prominent beneath, flat above; nerves (7-)8-9(-10) pairs, prominent beneath, impressed above, subparallel, at an angle of 40-50°, arcuating but not anastomosing towards the margin; reticulation fine, subscalariform, obscure; petiole glabrous, 8-15 mm, 1-3 mm ø, adaxially flat. Inflorescence male or androgynous, densely yellowish brown stellate hairy; bracts and bracteoles narrowly ovate to linear, 1-2 by ⅓-½ mm. Male rachis 10-15 cm, 1-1½ mm ø; ♂ flowers in clusters of 3-5, filaments 3-5 mm, anthers 0.35 mm long, pistillode globose, 0.7-1 mm ø. Androgynous rachis 5-10 cm long, 1 mm ø; female flowers solitary, staminodes rudimentary, styles 3-4, conical, c. 1 mm, recurved. Ripe cupule sessile, deeply cup-shaped, 1½-2 cm long, 2½-3 cm ø; rim thin, covering ⅓-½ part of the fruit; wall woody, densely fulvous tomentose; basal part ridged or tuberculate, upper part with 5-7 obscure lamellae. Ripe fruit subhemispherical, 1½-1¾ cm long, 2-2½ cm ø, densely fulvous tomentose by adpressed stellate hairs, top rounded-umbonate, base truncate, scar flat, c. 2 cm ø; wall woody, c. 2 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
