Tree 6-10 m. Branchlets initially densely set with fulvous erect simple hairs, later subglabrous, greyish to blackish brown, sparsely to densely lenticellate; terminal buds ovoid-ellipsoid, 1-2 by ½-⅔ mm, scales ovate-acute, densely silvery pubescent by simple adpressed hairs. Stipules linear-acute, 15-20 by 1-1½ mm. Leaves thin-coriaceous, (12-)20-30(-34) by (4-)5-8(-10) cm (index (2½-)3-4(-4½)), broadest at or rarely above the middle; surfaces more or less concolor-ous, glabrous, pale greyish green, above glossy, beneath dull; base acute, rarely rounded, top abruptly acute; midrib strongly prominent on both sides; nerves (12-)14-17(-20) pairs, strongly prominent beneath, impressed above, subparallel, at an angle of 45-60°, arcuating and anastomosing near the margin; reticulation lax, fine, scalariform, rather distinct beneath; petiole ¾-2 cm, 2-4 mm ø, adaxially flat. Inflorescence male or female, sparsely to densely fulvous stellate hairy; bracts and bracteoles ovate-acute, ⅔-3 by ⅔-1 mm. Male rachis 15-35 cm, 1½-2 mm ø; ♂ flowers solitary or in clusters of 2-3, filaments 3-4 mm, anthers 0.3 mm long, pistillode subglobose, compressed, ⅔-2 mm ø. Female rachis 10-15 cm, 3 mm ø; ♀ flowers solitary, rarely in clusters of 2-3, staminodes rudimentary, styles 3-4, conical, 1-1½ mm, recurved. Ripe cupule sessile, solitary, rarely in clusters of 2-3, saucer-to cup-shaped, ⅓-1 cm long, 2-2⅔ cm ø; rim thin, undulate and recurved, covering ¼-⅓ part of the fruit; wall woody, thin, inside densely fulvous tomentose by adpressed simple hairs, outside densely fulvous stellate hairy; scales adpressed, imbricate. Ripe fruit ovoid-ellipsoid, 2-2½ cm long, 1⅔-2 cm ø, glabrous, pale chocolate-brown, glossy, top gradually rounded-acute, base rotundate, scar concave, ⅔-1 cm ø; wall woody, c. 1 mm thick, for the greater part free from the cupule.
