Characteristics

Tree 15-20 m, 50 cm ø. Branchlets initially densely set with fulvous, adpressed, stellate hairs, later glabrous, greyish, sparsely lenticellate; terminal buds ovoid-ellipsoid, 2-3 by 1-1½ mm, scales narrowly ovate to linear, densely fulvous tomentose by adpressed, stellate hairs. Stipules linear-acute, 5-10 by 1-1½ mm, rather long persistent. Leaves thin-coriaceous, (9-)15-20(-28) by (4-)5-7(-10) cm (index (1.7-)2-3(-3.7)), broadest at or above the middle; surfaces concolorous, glabrous, greyish green, dull; base acute, rarely rounded, margin recurved, top acute; midrib and nerves strongly prominent beneath, flat to impressed above; nerves (6-)9-10(-12) pairs, parallel, at an angle of 50-60°, arcuating but not anastomosing towards the margin; reticulation fine, dense subscalariform to irregular, rather distinct beneath; petiole 8-15 mm, 2-4 mm ø, corky, adaxially flat. Male rachis 6-10 cm, 1-2 mm ø, densely fulvous stellate hairy; bracts and bracteoles narrowly ovate 1½-2 by ⅓-⅔ mm; ♂ flowers solitary, perianth strongly recurved, filaments 3-4 mm, anthers 0.3-0.4 mm long, pistillode subglobose, 1-1½ mm ø. Fruiting rachis 15-35 cm, 5 mm ø, carrying a few solitary cupules. Young fruit: perianth strongly recurved, staminodes well-developed and exceeding the perianth, styles 3-4, terete, 2-2½ mm, strongly recurved. Ripe cupule sessile, cup-shaped, ⅔-1 cm long, 2½ cm ø; rim thin, occasionally recurved, covering the basal part of the fruit; wall woody, thin, inside densely silky, fulvous tomen-tose by minute, adpressed simple hairs, outside densely fulvous stellate hairy by adpressed hairs; scales thick, ovate, adpressed, imbricate. Ripe fruit ovoid-ellipsoid, 3-3½ cm long, 2-2½ cm ø, glabrous, chocolate-brown, top abruptly rounded-acute, base truncate, scar concave to flat, 1-1½ cm ø; wall woody, 1 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
