Tree 7-27 m, 20-60 cm ø; stilt-roots occasionally present, up to 1.8 m tall; bark smooth, light grey. Branchlets initially sparsely greyish stellate hairy, later glabrous, greyish to blackish brown, sparsely to densely lenticellate; terminal buds ovoid-ellipsoid, 3-4 by 2 mm, scales narrowly ovate-acute. Stipules narrowly ovate-acute to subulate, 3-4 by 1-2 mm. Leaves thin-coriaceous, rigid, (6-)7-10(-11½) by (2-)2½-3½(-5) cm (index 2-3), broadest about the middle; above glabrous, glossy, pale greyish green to yellowish brown, underneath sparsely tomentose by greyish to chocolate-brown, adpressed, minute, stellate hairs, glabrescent; base acute or rounded, margin recurved, top bluntly or sharply 1-1½ cm acuminate; midrib strongly prominent on both sides; nerves thin, obscure to rather prominent beneath, 9-11 pairs, subparallel, at an angle of 45-60°, arcuating and anastomosing near the margin; reticulation fine, areolate, obscure; petiole 5-8 mm, 1 mm ø, glabrous, furrowed. Inflorescence male or androgynous, densely greyish brown, stellate hairy, hairs adpressed, minute; bracts and bracteoles broadly or narrowly ovate, ⅓-1½ by ⅔ mm. Male rachis 5-15 cm, 1-2 mm ø; ♂ flowers in clusters of 3, perianth 5-6-lobed, stamens 10-12, filaments 2½-3½ mm, anthers 0.25 mm long, pistillode subglobose, c. ⅔-1 mm ø. Androgynous rachis 5-10 cm, 1-1½ mm ø; female flowers solitary, staminodes rudimentary, styles 3, conical, c. 1 mm, recurved. Ripe cupule sessile to 3-4 mm stalked, saucer-shaped, 2-6 mm long, 15-22 mm ø; rim thin, undulate, recurved, covering the basal part of the fruit; wall woody, thin, inside densely tomentose by adpressed, simple hairs, outside densely greyish stellate hairy; lamellae 5-6, thin, concentric, denticulate. Ripe fruit ovoid-conical, 1.2-2.2 cm long, 1.6-2.3 cm ø, glabrous, dark purplish brown, top rounded-acuminate, base rotundate, scar deeply concave, 9-15 mm ø; wall bony, c. 1.2 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
