Leaves sessile or subsessile, elliptic-oblong to obovate-oblong, adaxially glabrous and obscurely verruculose-punctate, apex short-acuminate, base cordate-clasping, the margin entire to rounded-denticulate; petioles (when present) to 1 cm long. Panicle 12-30 cm long, the 5-merous sessile flowers borne in interrupted glomerules on the branches, the narrow triangular deciduous bracteoles 0.5-1 X 0.5 mm. Calyx tube ca. 0.25 mm long, the undulate hyaline lobes 0.5 mm long, the exterior teeth 0.25 mm long, adnate to and not projecting beyond the lobes. Petals glabrous, obovate, 2-2.5 X 1.5-2 mm. Anthers somewhat anisomorphic, 2-2.5 mm long, white, linear-oblong with a somewhat ventrally inclined pore; connective of the larger anthers prolonged 0.25 mm and modified basally into an irregularly lobed biauriculate appendage that skirts the filament insertion, connective of the smaller anthers briefly prolonged and modified ventro-basally into a laterally incurved bilobed appendage. Style glabrous, 5 mm long; stigma clavate-truncate; ovary 3-locular, 1/2 inferior, apex glabrous; berry 6 X 4-6 mm, purple at maturity.
