Tree 20-50 m, 30-100 cm ø; buttresses up to 1½ m tall; bark grey, shallowly fissured. Branchlets initially with a dense reddish brown indu-ment, later glabrous, pale to greyish brown, sparsely lenticellate; terminal bud ovoid-ellipsoid, 3-5 by 2-3 mm, scales narrowly ovate to linear. Stipules narrowly ovate or subulate, 5-9 by 1-2 mm, rather long persistent. Leaves thick-coriaceous, (5-)8-12(-16) by (2-)3-4(-6) cm (index 2-3), broadest at or slightly below the middle; surfaces more or less concolorous, above glabrous, dull, beneath densely greyish tomentose by adpressed, stellate hairs, glabrescent; base acute to cuneate, rarely rounded, margin entire, recurved, top bluntly acute to ½-1 cm acuminate; midrib prominent beneath, slightly so above; nerves 10-14 pairs, obscure on both sides, subparallel, at an angle of 45-60°, arcuating and anastomosing towards the margin; reticulation fine, areolate, distinct beneath; petiole ½-1½ cm, 1-2 mm ø, adaxially flat. Inflorescence male, androgynous, or mixed, densely fulvous-tomen-tose by stellate hairs; bracts linear-acute, 1-3 by ½-1 mm, bracteoles ovate-acute, 1-1½ by ⅔-1 mm. Male rachis 10-20 cm, 1-2 mm ø; ♂ flowers in clusters of 3-7, perianth 6-lobed, stamens 12-16, filaments 3-4 mm, anthers 0.3-0.4 mm long, pistil-lode subglobose, 1-1½ mm ø. Androgynous or mixed rachis 5-10 cm, 1½-2 mm ø; female flowers solitary, sometimes in clusters of 2-3, perianth 6-lobed, staminodes 12, rudimentary, styles 3, conical, 1-1½ mm, connate. Young cupule solitary or in clusters of 2-3, obovoid to ellipsoid, 1-2½ cm stalked; outside with 5-8 more or less concentric, prominent lamellae, densely greyish brown stellate-tomentose, apical opening ½-1½ cm ø. Ripe cupule sessile or 1-1½ cm stalked, ellipsoid-globose or obovoid, 3-5 cm long, 3½-5½ cm ø, covering the fruit almost completely or with an apical opening of ½-3 cm ø; wall woody, 2-3 mm thick, outside with 5-10 thin to strongly prominent lamellae, densely greyish tomentose by simple and stellate hairs. Ripe fruit depressed ovoid-globose, 3-4 cm long, 3½-5 cm ø; wall woody, ½-1 cm thick, for the greater part adnate to the cupule, upper free part flat to convex, ½-3½ cm ø, densely greyish brown tomentose, glabrescent; scar rounded, rugose; cotyledons flat-convex.
