Leaves (thinly) coriaceous, elliptic-oblong or oblong-lanceolate, 8-20 by 2-6 cm, base rounded or short-acute, apex acute(-acuminate) (sometimes ± blunt); upper surface olivaceous, late glabrescent on midrib towards base, lower surface with persistent indumentum, hairs grey-brown or cinnamon, interwoven, scale-like, 0.1-0.2 mm, mixed with scattered dendroid hairs 0.3-0.4 mm; not obviously papillose; dots absent; midrib little raised above, lateral nerves 12—15(—18) per side, at 60-70° to the midrib, faint, flat or sunken, lines of interarching and venation faint or invisible on both surfaces; petiole 7-15 by 1.5-2.5 mm; leaf bud 10-15 by 2.5-3 mm, hairs coarse, 0.5(-l) mm. Inflorescences between the leaves or below, with brown-red hairs 0.5(-l) mm, of the Knema-typt: sessile or to 2 mm long pedunculate, single or paired brachyblasts, bracts subpersistent, c. 1.5 mm long; in male: to 10 mm long, at apex with some flowers, buds of various sizes; in female 2-3 mm long, with 1-4 flowers; flowers with hairs 0.3-0.5(-l) mm. Male flowers: pedicel (2-)3 by 1 mm, bracteole subcircular, entire or faintly 3-topped, 1.5 by 2 mm, subpersistent; buds ± ovoid to ellipsoid-oblong, 4-5 by 2-2.5 mm, cleft 1/4-1/2, lobes 0.3 mm thick. Androecium 3.5 mm; androphore c. 1 mm, towards base with dense hairs 0.3-0.5 mm; synandrium 2.5 by 0.6 mm, thecae 10-12, sterile apex blunt, 0.2 mm long, glabrous or with few minute hairs 0.1 mm. Female flowers: pedicel c. 1 mm long, bracteole minute, buds ovoid, c. 4 mm, ovary ovoid, including short stigma 2.5 mm long, minutely pubescent. Fruits solitary, almost sessile, broadly ellipsoid, 2.5-3.5(-3.8) by 2-2.4 cm (remnant of the style ± acute, glabrous, blackish brown, 0.5 mm long), hairs mealy, 0.2-0.5 mm; pericarp 1-2 mm thick; seeds (broad-)ellipsoid, 2.5 cm, red-brown, glossy; fruiting pedicel rather stout, 3-6 mm long.
