    Description: Shrubs 1-4 m tall, the branchlets, petioles, elevated primary leaf veins beneath, inflorescences, and hypanthia moderately to densely covered with stalked-stellate hairs. Leaves 3-5-nerved, elliptic to elliptic-ovate, 8.6-21 X 4.5-10 cm, adaxially sparsely to moderately strigose with smooth hairs 1-3 mm long (the hairs occasionally forked distally), abaxially sparsely to moderately covered with stalked-stellate hairs on the surface, apex acuminate, base broadly acute to rounded, the margin repand-denticulate; petioles 0.5-2 cm long. Panicle 5-15 cm long; flowers sessile, 5-merous, born in congested bracteate terminal glomerules, the tardily deciduous bracteoles ovate to elliptic, 3-6 mm long. Calyx tube 0.5 mm long, the broadly rounded lobes ca. 0.5 mm long, sparsely stellulate-ciliolate, the subulate exterior teeth ca. 0.5 mm long. Petals oblong-obovate, glabrous, 2-4 X 1-2.5 mm. Anthers somewhat unequal in size, linear-oblong to subulate, alternately 2.5-3 mm and 3.5-4 mm long, white, the larger with a ventrally inclined pore, the smaller with a truncate or retuse pore; connective not prolonged but adnate to the thecae and ventrally bilobed at the base. Style glabrous, 6-8 mm long, stigma capitate; ovary 3-locular, 1/2 inferior, apex elevated into a low dome-like glabrous cone; berry 5-6 X 5-6 mm, purple-black at maturity.
