Leaves: petiole 3–6 cm, puberulent with stalked glands; blade pentagonal with nearly parallel sides, 3–5-lobed, cleft less than 1/2 to midrib, 2 middle sinuses deepest, to 8.5 cm, base broadly truncate to shallowly cordate, surfaces not glandular, ± hairy abaxially, glabrous adaxially, lateral lobes (directed forward), broadly triangular to ovate-triangular, margins coarsely bicrenate-dentate, apex acute. Inflorescences pendent, 6–13-flowered racemes, 3–5 cm, axis glabrous or sparsely pubescent, glands short-stipitate, flowers evenly spaced. Pedicels jointed, 1–4 mm, short stipitate-glandular; bracts ovate-orbiculate to oblong, 1.5–2 mm, stipitate-glandular. Flowers: hypanthium dark reddish purple or greenish white and strongly purplish-maculate or tinged, saucer-shaped, to 1 mm, glabrous; sepals with adjacent lobes overlapping, spreading, greenish purple, cuneate-rhombic, 2 mm; petals widely separated, erect, reddish purple, spatulate, not conspicuously revolute or inrolled, 1 mm; nectary disc prominent, reddish purple, 5-lobed, covering top of ovary; stamens nearly as long as petals; filaments linear, 0.2–0.5 mm, glabrous; anthers white, transversely oblong-cordate, 0.2–0.3 mm, apex shallowly notched (anther sacs almost adjacent); ovary glabrous; styles connate 1/3–3/4 their lengths, 1–1.2 mm, glabrous. Berries sour-tasting, red, ovoid, 6–10 mm, glabrous.
