Tree 10-25 m, 30-130 cm ø; bark pale grey, finely fissured. Branchlets initially densely yellowish brown stellate hairy, later glabrous, greyish brown, densely lenticellate; terminal buds ovoid-globose, 3-4 by 2-3 mm, scale broadly ovate. Stipules ovate, 2½ by 1½ mm. Leaves thick-coriaceous, rigid, (12-)15-17(-22) by (5-)6-8(-10) (index 1.6-2.8), broadest at or below the middle; surfaces discolorous, above glabrous, pale to dark greyish brown, glossy, beneath densely glaucous-tomentose by adpressed-stellate hairs; base rounded-acute to cuneate, margin recurved, top bluntly acute to 1-1½ cm acuminate; midrib prominent on both sides; nerves (7-)8-9(-10) pairs, prominent beneath, flat above, subparallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation fine, subscalariform, obscure to distinct beneath; petiole glabrous, 1-2 cm, 3-4 mm ø, terete or adaxially flat. Inflorescence male or mixed, densely yellowish brown stellate hairy; bracts and bracteoles ovate-acute, 1-1½ by ⅔ mm. Male rachis 10-25 cm, 2-3 mm ø; ♂ flowers solitary or in clusters of 2-3, filament 2½-3 mm, anthers 0.35-0.50 mm long, pistillode subglobose, 1½-2 mm ø. Mixed rachis 5-20 cm, 2-3 mm Ø; female flowers solitary or in clusters of 3, staminodes rudimentary, styles 3-4, conical, c. 1 mm long. Ripe cupule subsessile, cup-shaped, 1.2-1.5 cm long, 2-2½ cm ø; rim thin, covering c. ¼ part of the fruit; wall woody, rather thick, outside densely greyish brown stellate hairy; lamellae 7-9, thin, entire, concentric. Ripe fruit ovoid, 2-2½ cm through, densely greyish tomentose by adpressed, simple hairs, top gradually rounded-apiculate, base truncate, scar flat to slightly convex, 1-2 cm Ø; wall woody, 2-3 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
