Leaves coriaceous, when immature with dense hairs (2-)5-i mm long, (oblong-)lanceolate, ± narrowed towards the base, 25-60 by 5-22 cm, apex subobtuse, acute, or acuminate, base subattenuate, rounded, or subcordate; olivaceous to dark brown above, lower surface glabrescent, greyish, faintly papillate or not; dots absent; midrib raised above; nerves 25-33 pairs, ± raised above, reddish to yellowisl brown; venation distinct; petiole 10-30 by 8-12 mm, late glabrescent, hairs (1—)2—3 mn long. Inflorescences: sessile, brachyblast simple or 2-4-furcate, up to 20 mm in diameter, in male 5-20-flowered, in female 4-10-flowered; flowers with dense woolly hairs 1-3 mm long, perianth 3-(or 4-)lobed, striate and red inside. Male flowers: pedicel 15-20 mm long, bracteole caducous, at or somewhat above the middle; buds depressed globose-obovoid, 7-9 by 8-10 mm, cleft c. 2/3, lobes 1-2 mm thick; staminal disc blunt-triangular, ± concave, 3-4 mm in diameter; anthers 15-25, just sessile, half-erect or horizontal, 0.6-1 mm, not touching; androphore ± tapering, 2(-3) mm long. Female flowers: pedicel (5-) 10-20 mm long, bracteole ± median to subapical; buds subglobose, or ovoid, or depressed-obovoid, 8-10 by 8-10 mm, cleft about halfway, lobes 1-2.5 mm thick; ovary subglobose, 2-4 mm in diameter, hairs 2 mm long; style 1.5-2 mm long, stigma ± 2-lobed and each lobe again 3-or 4-lobulate, these again 2-4-lobulate, hence stigma c. 20-lobulate-serrate.
