Branchlets densely set with fulvous to rufous erect tuft-hairs with 2-many arms, later subgla-brous, dark greyish brown, finely fissured, sparsely to densely lenticellate; terminal buds ovoid, 3-5 by 2-3 mm, scales ovate. Stipules broadly ovate to lanceolate, 3-10 by 2-5 mm, rather long persistent. Leaves thin-coriaceous, (12-)14-18(-20) by (5-)6-7(-8) cm (index 2-3), broadest at the middle; surfaces discolorous, above dark brown, densely pubescent especially on the midrib and nerves, subglabrescent, dull to glossy, beneath densely set with fulvous to rufous, adpressed stellate hairs and erect tuft-hairs; base rounded, margin occasionally strongly recurved, top rounded and abruptly acute to ½-1 cm acuminate; midrib strongly prominent on both sides; nerves 12-16 pairs, strongly prominent beneath, flat to impressed above, parallel, at an angle of 50-60°, arcuating and anastomosing near the margin; reticulation dense, scalariform, distinct beneath; petiole ½-1 cm, 2 mm ø, terete or adaxially flat, densely fulvous to rufous pubescent. Inflorescence male, androgynous or mixed, in densely subterminal paniculate clusters, densely fulvous to rufous pubescent; bracts and bracteoles narrowly ovate, 1-1½ by ½-⅔ mm. Male rachis 5-15 cm, 1-2 mm ø; ♂ flowers solitary or in clusters of 2-3, filaments 2-3 mm, anthers 0.25-0.3 mm long, pistillode globose, 1 mm ø. Androgynous or mixed rachis 10-20 cm, 2 mm ø; female flowers solitary, rarely in clusters of 2-3, staminodes rudimentary, styles 3-4, conical, 1-1½ mm, recurved. Ripe cupule sessile to½ cm stalked, saucer-to cup-shaped, ½-1 cm long, 2-3 cm ø; rim thin, covering the basal part of the fruit; wall woody, 2-3 mm thick, inside densely fulvous tomentose by adpressed, simple hairs, outside densely fulvous to rufous tomentose by adpressed stellate hairs; scales subulate, 3-5 mm long, patent or recurved, more or less concentrically set. Young fruit with a long acuminate top. Ripe fruit depressed-ovoid, 1½-2 cm long, 2-3 cm ø, glabrous, dark purplish brown, top rounded-acute to rounded-acuminate, base rotundate, scar flat to concave, 1½-2 cm ø; wall woody, 1-2 mm thick, for the greater part free from the cupule.
