Tree 15-33, 20-130 cm ø; buttresses up to 2 m tall, spreading; bark greyish brown, smooth to deeply fissured or scaly. Branchlets initially densely fulvous to rufous tomentose by simple and stellate hairs, later subglabrous, sparsely to densely lenticellate; terminal buds ovoid-ellipsoid, 4-5 by 2-3 mm, scales linear. Leaves thick-coriaceous, (10-)18-25(-35) by (5-)8-10(-17) cm (index 1.7-3.4), broadest about the middle; above glabrous, or sometimes with some rufous tomentum on midrib and nerves, dull to glossy, underneath glaucous-tomentose by adpressed stellate hairs; base rounded to acute, margin recurved, top bluntly to sharply acute to 1-2 cm acuminate; midrib strongly prominent on both surfaces; nerves (7-)9-10(-12) pairs, flat on both sides, parallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation dense,fine, scalariform, obscure to distinct beneath; petiole (½-)1-1½(-2½) cm, 2-3 mm ø, subglabrous, adaxially flat. Inflorescence male or androgynous, densely yellowish brown stellate hairy; bract and bracteoles narrowly ovate, 1-1½ by ½ mm. Male rachis 15-20 cm, 2-3 mm ø; ♂ flowers in clusters of 3, filaments 3-5 mm, anthers 0.20-0.35 mm long, pistillode globose, c. 1½ mm ø. Androgynous rachis 10-25 cm, 2-3 mm ø; female flowers solitary, rarely in clusters of 3, staminodes rudimentary, styles 3-4, conical, 1-2 mm, recurved. Ripe cupule sessile to 1 cm stalked, deeply cup-shaped, 1⅓-2 cm long, 4-5 cm ø, rim recurved (sometimes very strongly), entire or undulate, covering ⅓-½ part of the fruit; wall woody, densely glaucous to fulvous adpressed stellate-tomentose; lamellae thin, obscure, denticulate, the scales sometimes rather distinct. Ripe fruit depressed subglobose or globular-cylindrical, 3-4 cm in size, top rounded to depressed-umbonate, base truncate, scar deeply concave, conical, c. 1½-2 cm ø; wall woody, 2-4 mm thick, outside densely greyish tomentose by adpressed simple hairs, greater part free from the cupule; cotyledons flat-convex.
