Tree 12-29 m, 25-100 cm ø; bark greyish brown, smooth to scaly, lenticellate. Branchlets initially densely greyish brown tomentose by adpressed, stellate hairs, glabrescent, densely warty lenticellate; terminal buds ovoid-globose, 3-4 by 2-3 mm, scales ovate. Stipules linear to lanceolate, 10-15 by 2-3 mm. Leaves thick-coriaceous, rigid, (10-)12-18 (-27) by (3½-)5-7(-10) cm (index 2.2-4.5), broadest about the middle; surfaces more or less concolorous, above glabrous, glossy, underneath densely greyish brown, tomentose by adpressed, stellate hairs, glabrescent; base acute to cuneate, rarely rounded, margin recurved, top acute to 1-1½ cm acuminate; midrib prominent beneath, slightly so above; nerves (5-)6-8(-10) pairs, prominent beneath, obscure above, subparallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation lax, sub-scalariform, obscure on both sides; petiole 1-2 cm, 2-4 mm ø, glabrous, adaxially flat. Ripe cupule sessile to 1 cm stalked, depressed-ovoid-globose, 2½-3 cm long, 3-5½ cm ø; wall 2-10 mm thick, brittle, covering the fruit almost completely except for an opening of smaller than ½ cm ø, outside irregularly set with rounded to pointed short tubercles; dehiscence irregular. Ripe fruit depressed ovoid-globose, 1½-2½ cm long, 2-4 cm ø, base truncate, scar flat to concave, 1½-2½ cm ø, top rounded and depressed umbonate at the centre; wall for the greater part free from the cupule, 2-8 mm thick, densely yellowish brown to fulvous tomentose; cotyledons flat-convex.
