Stipules ovate-acute, 4-5 by 2-3 mm, longitudinally ribbed and rather long persistent. Leaves thick-coriaceous, rigid, (4-)6-8(-10) by (3-)4-5(-6) cm (index (1.3-)1.7(-2)), broadest at or below the middle; surfaces disco-lorous, above dark chocolate-brown, dull to glossy, sparsely stellate pubescent especially on the midrib and nerves, beneath densely set with yellowish brown, adpressed stellate and erect simple or stellate hairs; base acute to rounded-acute, sometimes asymmetrical, margin strongly recurved, sometimes undulate, top bluntly acute to abruptly ½-1 cm acuminate; midrib and nerves strongly prominent beneath, flat to impressed above; nerves 8-10 pairs, dense, parallel, at an angle of 40-60°, arcuating but not anastomosing towards the margin; reticulation fine, dense, scalariform, obscure to distinct beneath; petiole 5-7 mm, 2-3 mm ø, densely stellate pubescent, glabrescent, adaxially flat. Inflorescence male or androgynous, densely yellowish to fulvous stellate hairy; bracts and bracteoles narrowly ovate-acute, 1-4 by ½-1 mm. Male rachis 5 cm, 1-1½ mm ø; ♂ flowers in clusters of 3, filaments 2½-3 mm, anthers 0.3-0.35 mm long, pistillode globose, 1 mm ø. Androgynous rachis 3-4 cm, 1-1½ mm ø; female flowers solitary, staminodes rudimentary, styles 3, terete, 1-1½ mm, recurved. Ripe cupule subsessile, cup-shaped, ½-1 cm long, 2-2½ cm ø; rim thin, covering c. ⅓ part of the fruit; wall woody, thin, inside densely fulvous tomentose by adpressed simple hairs, outside densely fulvous adpressed stellate hairy; scales linear, 5 mm long, free, irregularly set or in obscure concentric rows. Ripe fruit ovoid-conical, 2-2½ cm long, 1½-2 cm ø, glabrous, chocolate-brown, top rounded-acute, base rotun-date, scar flat, 1 cm ø; wall woody, 1 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
