Branchlets glabrous, with thick nodes, dark greyish brown, sparsely lenticellate; terminal bud ovoid, 1-3 by ½-1 mm, scales narrowly ovate, initially densely rufous lepidote, glabrescent. Stipules linear-acute, c. 2 by ½ mm. Leaves thick-coriaceous, rigid, (6-)8-10(-12) by (3-)4-5(-6) cm (index (1.6-)2(-3)), broadest at the middle; surfaces slightly discolorous, above glabrous, glossy, chocolate-brown, underneath densely yellowish brown tomentose by adpressed, minute, stellate hairs; base acute, top abruptly acute or 1-1½ cm acuminate; midrib broad, prominent above, flattish beneath, nerves 8-10 pairs, thinly prominent beneath, flat above, subparallel, at an angle of 30-50°, arcuating but not anastomosing towards the margin; reticulation fine, subscalariform, obscure; petiole glabrous, 8-12 mm, 2-3 mm ø, adaxially flat. Inflorescence male or androgynous, solitary or in dense paniculate clusters, densely or sparsely tomentose by stellate hairs; bracts narrowly ovate, 1-2 by ½-⅔ mm, bracteoles ovate, c. ½ by ½ mm. Male rachis 3-10 cm, 1-2 mm ø; ♂ flowers in clusters of 3, filaments 2-3 mm, anthers 0.25 mm long, pistillode subglobose, ⅔-1 mm ø. Androgynous rachis c. 5 cm, 2 mm ø; female flowers solitary or rarely in clusters of 2-3, staminodes rudimentary, styles 3, conical, 1-2 mm, connate. Young cupule solitary or in clusters of 2-3; scales adpressed, minute, concentrically arranged. Ripe cupule sessile, solitary, cup-shaped, ⅔-1 cm long, 2-2½ cm ø; rim thin, covering ¼-⅓ part of the fruit; wall woody, thin, inside densely greyish tomentose by adpressed simple hairs, outside densely fulvous-tomentose by short stellate hairs; lamellae thin, 4-6, obscure, minutely denticulate. Ripe fruit ovoid-globose, 1-1½ cm long, 1¾-2⅓ cm ø, glabrous, pale chocolate-brown, top rounded-acute, base rounded, scar deeply concave, c. 1 cm ø; wall woody, c. 1 mm thick, for the greater part free from the cupule.
