Leaves: stipules 3–6 mm; petiole 1/2–2/3 blade; blade broadly cordate, 7–12 cm, usually 3-shouldered to shallowly 3-lobed, apex usually short acuminate, abaxial surface not glaucous, sparsely arachnoid to glabrate, visible through hairs, veins sparsely hirtellous, adaxial surface slightly arachnoid to glabrate. Inflorescences 3–7(–9) cm. Flowers functionally unisexual. Berries black, heavily glaucous, globose, 8–12 mm diam., skin separating from pulp; lenticels absent. 2n = 38.
