Medium-sized tree. Young twigs, panicle, leaf bud, stipule outside (puberulent within), petiole, leaf beneath and midrib above densely persistent-scabrid tawny tomentose; leaf above fugaceous pubescent. Twig 2-3 mm ø apically, terete, becoming rugulose, verrucose, much branched; stipule scars to 1.5 mm long at first, 0.5 mm thick, shortly cuneate, obscured by tomentum. Bud 4-6 by 4-5 mm, broadly ovoid, slightly compressed, subacute. Stipule to 18 by 8 mm, broadly hastate, subacute, constricted at base, caducous. Leaves 7-20 by 4-9 cm, oblong-obovate to oblong-ovate, thinly coriaceous; base obtuse, rarely subcordate; acumen to 8 mm long, short, deltoid; nerves 14-17 pairs, rather slender, curved, at 40°-50°, more widely at base; tertiary nerves distinct, rather densely scalariform; midrib prominently terete beneath, slightly depressed or applanate above; petiole 1.8-2.5 cm long. Panicle to 8 cm long, short, lax, terminal or axillary, terete or ribbed; singly branched, the branchlets bearing to 3 +-secund flowers; bracteoles to 4.5 by 3 mm, narrowly deltoid, acute, scabrid pale fulvous pubescent outside, puberulent within, fugaceous. Flower bud to 8 by 5 mm, ovoid, obtuse. Calyx densely yellow-brown pubescent; 3 outer lobes deltoid to ovate, frequently acuminate, acute; 2 inner lobes similar but smaller. Petals pink, narrowly lanceolate, densely setose on parts exposed in bud. Stamens 15, the 5 innermost somewhat longer than the other; filaments basally expanded, abruptly contracted and filiform distally; anther ± oblong; appendage to connective reaching the style apex on 5 inner stamens, more than twice as long as anther cells, becoming curved but not reflexed. Ovary subglobose, small, shortly densely pubescent; style and stylopodium 3 times as long as ovary, filiform with glabrous apex, swelling slightly below it and densely shortly pubescent; frequently further swollen in the basal half. Fruit calyx shortly evenly fulvous pubescent; 3 longer lobes to 4.5 by 1 cm or shorter, unequal, variable, shortly spatulate, subacute, to 7 mm broad above the to 2 by 3.5 cm broadly ovate shallowly saccate thickened base, closely adpressed to the base of nut; 2 shorter lobes to 3 by 0.3 cm, linear, similarly expanded at base. Nut to 5 by 2.5 cm large, obovoid, tapering to an acute apical style remnant, densely evenly fulvous pubescent, becoming the same length or slightly longer than the calyx.
