Characteristics

Tree 10-25 m, 20-60 cm ø; buttresses ½-1 m tall, ⅓-½ m out, 6 cm thick; bark greyish brown, scaly. Branchlets initially densely fulvous tomen-tose by stellate hairs, soon glabrous, dark greyish brown or yellowish grey, sparsely to densely lenti-cellate; terminal buds ovoid-ellipsoid, 2-4 by 1-1½ mm, scales narrowly ovate-acute. Stipules lanceolate to subulate, 2-5 by 1-2 mm. Leaves thin-coriaceous, (8-)11-15(-16) by (2½-)4-6(-6½) cm (index (2-)2½-3(-3½)), broadest at or above the middle; surfaces concolorous, glabrous, glossy, pale greyish green; base attenuate-acute, top abruptly acute to 1 cm acuminate, tip blunt or sharp; midrib strongly prominent on both sides; nerves 7-8 pairs, prominent beneath, flat above, subparallel, at an angle of 45-50°, strongly arcuating but mostly not anastomosing towards the margin; reticulation fine, dense, scalariform, more or less distinct on both surfaces; petiole 4-6 mm, 1½-2 mm ø, terete or adaxially flat, glabrous. Inflorescence male or androgynous, densely fulvous stellate hairy, subglabrescent; bracts and bracteoles ovate-acute, ⅓-1½ by ⅓-½ mm. Male rachis 5-25 cm, 1 mm ø; ♂ flowers in clusters of 2-3, stamens 8-12, filaments 2-2½ mm, anthers 0.25-0.3 mm long, pistillode subglobose, 1 mm ø. Androgynous rachis 5-10 cm, 1 mm ø; female flowers solitary, staminodes rather well-developed but not exceeding the perianth, styles 3, terete, 2½-3 mm, recurved. Ripe cupule sessile, cup-shaped, 1-1½ cm long, 1⅔-2¼ cm ø; rim thin, entire, covering the basal part of the fruit; wall woody, thin, inside densely greyish brown tomen-tose by adpressed, simple hairs, outside densely fulvous stellate hairy: scales adpressed, imbricate, rather woody and corky, occasionally fused at the base to form obscure lamellae. Ripe fruit cylindrical, 3-4½ cm long, 1½-2 cm ø, initially densely greyish tomentose by adpressed, minute simple hairs, soon glabrous, dull chocolate-brown, top abruptly rounded-acute, base truncate, scar flat, 1 cm ø; wall woody, 1 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
