Tree 15-25 m, 30-40 cm ø; bark smooth, grey-brown. Branchlets initially densely set with fulvous to rufous, adpressed stellate hairs, later glabrous, greyish black, densely lenticellate; terminal buds ovoid, 2 by 2 mm, scales narrowly ovate. Stipules ovate or deltoid, 1-2 by ½-1mm. Leaves thick-coriaceous, (4-)6-10(-12) by (2-)3-4(-5½) cm (index 1½-2½), broadest at or below the middle; surfaces more or less discolorous, above dark chocolate-brown, dull to glossy, with some adpressed stellate hairs especially on the midrib and nerves, and blackish glandular papillae, underneath densely yellowish brown to rufous tomentose by adpressed, minute, stellate hairs; base acute, top acute or rounded-emarginate; midrib prominent beneath, slightly so above; nerves (5-)6-7(-8) pairs, prominent beneath, impressed above, parallel, at an angle of 45-50°, arcuating but not anastomosing towards the margin; reticulation fine, dense, scalariform, obscure to rather distinct beneath; petiole ½-1 cm, 1-3 mm ø, shallowly furrowed. Inflorescence male or androgynous, in densely subterminal, paniculate clusters, densely yellowish brown to rufous stellate hairy; bracts and bracteoles narrowly ovate, 1-1½ by ½-1 mm. Male rachis c. 5 cm, 1-1½ mm ø; ♂ flowers in clusters of 2-3, rarely solitary, filaments 1½-2 mm, anthers 0.25 mm long, pistillode globose, c. 1 mm ø. Androgynous rachis 4-5 cm, 2 mm ø; female flowers solitary, rarely in clusters of 2, staminodes rudimentary, styles 3, conical, 1-1½ mm,recurved. Cupule (not fully ripe) sessile, saucer-shaped, 6 mm long, 10-15 mm ø; rim thin, covering the basal part of the fruit; wall thin, densely fulvous tomentose on both sides; scales minute, adpressed, imbricate but concentrically set. Fruit (not yet ripe) ovoid-conical, c. 1 by 1⅓ cm, glabrous, chocolate-brown, glossy, top acuminate, base ro-tundate, scar concave, c. 8 mm ø; wall bony, thinner than ½ mm, for the greater part free from the cupule.
