Tree 5-15 m, 10-25 cm ø; bark scaly, greyish brown. Branchlets initially densely yellowish to reddish brown tomentose by adpressed, stellate hairs, later subglabrous, greyish brown, sparsely lenticellate; terminal buds ovoid, 1-1½ by 1 mm, scales ovate-acute. Stipules deltoid, c. 1 by ½ mm soon caducous. Leaves thin-coriaceous (8-) 10-15(-17) by (3½-) 4-5(-6) cm (index 2-2.4), broadest at or slightly below the middle; surfaces more or less discolorous, above glabrous, dull to glossy, dark brown, beneath densely glaucous tomentose by adpressed stellate hairs; base acute, shortly decurrent, margin undulate, top 1-1½ cm acuminate; midrib prominent on both surfaces, stronger beneath; nerves (11-)12-14(-16) pairs, more or less prominent beneath, parallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation fine, dense, scalariform, obscure; petiole ½-1 cm long, 1 mm ø, adaxially flat or shallowly furrowed. Inflorescence male, female or androgynous, densely pale greyish brown stellate hairy; bract and bracteoles ovate to linear-acute, 1-2 by ⅓-½ mm. Male rachis 15-20 cm, 1 mm ø; ♂ flowers solitary or in clusters of 3, filaments 3-4 mm, anthers 0.3-0.35 mm long, pistillode subglobose, c. 1 mm ø. Female or androgynous rachis 10-15 cm, ø; ♀ flowers solitary, staminodes rudimentary, styles 3, conical, 1-1½ mm, recurved. Ripe cupule ½-1 cm stalked, ovoid or deeply cup-shaped, 1-1½ cm long, 2½-3 cm ø, covering the fruit for ⅔-¾ or almost completely; wall thinner than ½ mm, densely greyish brown tomentose on both surfaces; lamellae thin, concentric, denticulate; dehiscence irregular. Ripe fruit depressed-ovoid, c. 1½ cm long, 2½-3 cm ø, glabrous except for a small part at the long, acuminate top, base cordate, scar concave; wall bony, c. 1 mm thick, dark purplish brown, for the greater part free from the cupule.
