Characteristics

Tree 7-13 m, 10-15 cm ø; bark grey, smooth. Branchlets initially densely tomentose by adpressed stellate hairs, later glabrous, greyish to blackish brown, densely lenticellate; terminal buds ovoid-ellipsoid, 2-4 by 1-2 mm, scales narrowly ovate-acute. Stipules linear-acute, 4-5 by 1 mm. Leaves thin-coriaceous, (3-)6-8(-10) by (2-)3-3½(-4) cm (index (2-)2½(-3)), broadest at or below the middle; above glabrous, greyish green to chocolate-brown, dull to glossy, beneath with a thin cover of adpressed, minute stellate hairs, sometimes interspersed with some erect stellate hairs especially on the midrib and nerves, dull pale brown to greyish brown; base rounded-acute to acute, top rounded-acute to 1 cm acuminate, tip usually oblique; midrib prominent on both sides; nerves 6-8 pairs, thin, flat on both surfaces to impressed above, subparallel, at an angle of 45-60°, arcuating but not anastomosing towards the margin; reticulation subscalariform to irregular, obscure; petiole 5-8 mm, 1-1½ mm ø, adaxially flat or furrowed. Inflorescence male or androgynous, simple and axillary or much-branched and sub-terminal, densely fulvous stellate hairy; bract and bracteoles narrowly ovate-acute, 2-3 by ⅔-1 mm. Male rachis 5-10 cm, 1-1½ mm ø; ♂ flowers in clusters of 3, filaments 3-3½ mm, anthers 0.3 mm long, pistillode globose, ⅔-1 mm ø. Androgynous rachis 3-8 cm, 1½ mm ø; female flowers solitary, staminodes rather well-developed but not exceeding the perianth, styles 3, conical, 1-1½ mm, recurved. Ripe cupule ½-⅔ cm stalked, cup-shaped, ⅔-1 cm long, 1½-2 cm ø; rim thick, covering ¼-⅓ part of the fruit; wall woody, 1-2 mm thick, inside densely fulvous tomentose by adpressed simple hairs, outside densely fulvous tomentose to adpressed, minute, rather distinct on the upper half of the cupule, imbricate but set in concentric rows. Ripe fruit cylindrical to depressed subglobose, 1½-2¼ cm long, 1½-1¾ cm ø, densely fulvous tomentose by adpressed simple hairs, top acute or rounded-umbonate, base truncate, scar flat, 1-1⅓ cm ø; wall woody, 1-2 mm thick, for the greater part free from the cupule.
