Characteristics

Small tree, c. 10 cm ø; bark rough, light grey. Branchlets initially densely yellowish to fulvous tomentose by stellate hairs, later glabrous, greyish to dark brown, with sparse minute lenticels; terminal buds ovoid, 1 by 1 mm, scales ovate-acute. (Stipules not seen.) Leaves chartaceous, (7½-)10-12(-1½) by (2½-)3-5(-6) cm (index (2-)2½(-3)), broadest at the middle; surfaces discolorous, above dark chocolate-brown, sparsely stellate-pubescent, glabrescent, dull or glossy, beneath densely yellowish tomentose by adpressed stellate hairs; base attenuate-acute or rounded-acute, sometimes decurrent and asymmetrical, margin sometimes undulate, top bluntly acute to sharply 1-2 cm acuminate, tip usually oblique; midrib thin but prominent on both sides; nerves (8-)9-10(-12) pairs, thin, prominent beneath, flat above, subparallel, at an angle of 50-60°, arcuating but not anastomosing towards the margin; reticulation fine, dense, scalariform, obscure, or sometimes rather distinct beneath; petiole 7-13 mm, 1-2 mm ø, sparsely pubescent, shallowly furrowed. Inflorescence male or androgynous, densely yellowish to fulvous stellate-hairy; bracts and bracteoles ovate-acute, c. 1 by ⅔ mm. Male rachis 10-20 cm, 1-1½ mm ø; ♂ flowers in clusters of 3, filaments 3-3½ mm, anthers 0.3 mm long, pistillode subglobose, c. 1 mm ø. Androgynous rachis 10-20 cm, 2 mm ø; female flowers solitary, staminodes rudimentary, styles 3, conical, c. 1 mm, recurved. Ripe cupule sessile, saucer-shaped, ⅓-½ cm long, 2-2½ cm ø; rim thin, covering the basal part of the fruit; wall woody, thin, inside densely adpresssed pubescent by simple hairs, outside densely fulvous tomentose by adpressed stellate hairs; lamellae thin, denticulate, concentric or somewhat spiral. Ripe fruit ovoid-conical, 2-2⅓ cm through, glabrous, pale to dark chocolate-brown, top rounded-acute to acuminate, base rotundate, scar flat, c. 1½ cm ø; wall woody, c. 1 mm thick, for the greater part free from the cupule; cotyledons flat-convex.
