Characteristics

Tree 10-15 m, 25-60 cm ø. Branchlets initially densely fulvous to rufous tomentose by adpressed stellate hairs, later glabrous, whitish grey, densely warty lenticellate; terminal buds ovoid-ellipsoid, 2-3 by 1-2 mm, scales linear to narrowly ovate-acute. Stipules narrowly ovate to linear, 3-4 by 1-1½ mm, soon caducous. Leaves thin-coriaceous, (14-)18-26(-30) by (4-)6-8(-12) cm (index 2½-5), broadest at or above the middle; surfaces more or less concolorous, above glabrous, dull to glossy, underneath densely greyish tomen-tose by adpressed stellate hairs, subglabrescent; base acute, rarely rounded, margin recurved, top bluntly to sharply 1-1½ cm acuminate; midrib prominent on both sides; nerves (7-)8-11(-15) pairs, prominent beneath, impressed above, sub-parallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation fine, lax, subscalariform, obscure; petiole 1-1½ cm, 1½-4 mm ø, adaxially flat. Inflorescences male, androgynous or mixed, densely pale grey stellate hairy; bracts and bracteoles ovate, c. 1 by ½ mm. Male rachis 10-15 cm, 1 mm ø; ♂ flowers solitary or in clusters of 3, perianth (5-)6(-8)-lobed, stamens (10-)12(-13), filaments 3-4 mm, anthers 0.3-0.35 mm long, pistillode subglobose, longitudinally compressed, 1-2 mm ø. Androgynous or mixed rachis 10-20 cm, 2-4 mm ø; female flowers solitary, staminodes well-developed and exceeding the perianth, sometimes polliniferous; styles 3, conical, c. 2 mm, recurved. Ripe cupule sessile, saucer-shaped, ½-1 cm long, 2-3½ cm ø, covering the basal part of the fruit; rim thin, entire or undulate; outside densely greyish brown stellate hairy; lamellae 5-8, concentric, thin. Ripe fruit depressed-ovoid, 1-1½ cm long, 2½-3 cm ø, densely fulvous short stellate-tomen-tose; top rounded-umbonate, base rounded, scar deeply concave, 1-2 mm ø; wall bony, c. 1 mm thick, for the greater part free from the cupule.
