Tree 18-40 m, 20-120 cm ø; buttresses up to 2 m tall and out; bark deeply fissured or scaly. Branchlets initially densely yellowish brown to ful vous tomentose by adpressed stellate hairs, later glabrous, lenticellate; terminal buds ovoid-ellip soid, 3-6 by 2-3 mm, scales ovate to linear. Stipules narrowly lanceolate to linear, 10 by 3 mm. Leaves thick-coriaceous, rigid, (18-)20-25(-30) by (6-)7-9(-12) cm (index 2.5-3.5), broadest at or slightly below the middle; surfaces discolorous, above glabrous, dark chocolate-brown, glossy, underneath densely yellowish brown to fulvous adpressed stellate hairy; base rounded-acute, top bluntly 1-1½ cm acuminate; midrib and nerves strongly prominent beneath, slightly so to flat above; nerves (14-)15-17(-20) pairs, parallel, at an angle of 45-60°, arcuating but not anastomo sing towards the margin; reticulation dense, scala-riform, distinct beneath; petiole 1-2 cm, 2-3 cm ø, adaxially flat. Inflorescence male or androgynous, densely yellowish brown adpressed stellate hairy; bract and bracteoles thick-coriaceous, linear, 2½-3½ by ½ mm. Male rachis 10-15 cm, 2½-3 mm ø; ♂ flowers in clusters of 3, filaments 3-4 mm, anthers 0.25-0.3 mm long, pistillode globose, c. 1 mm ø. Androgynous rachis c. 10 cm, 3-4 mm ø; female flowers solitary or in clusters of 2-3, staminodes rudimentary, styles 3, conical, c. 1 mm. Ripe cupule sessile, broadly obconical to cup-shaped or saucer-shaped, 1½-2½ cm long, 4-6 cm ø, rim ½-1 cm thick, incurved, covering ⅓-½ part of the fruit; wall woody, lamellae 8-10, obscure, rounded, concentric or irregular, densely fulvous stellate hairy. Ripe fruit broadly depressed subglobose, 1½-2½ cm long, 3½-4½ cm ø, top depressed-umbonate, base rounded, scar strongly convex; wall woody, 3-5 mm thick, outside densely yellowish brown to fulvous tomentose with adpressed simple hairs, for the greater part free from the cupule.
