Inflorescences spreading, solitary flowers or 2(–4)-flowered corymbs, 4–5 cm, axis pilose and stipitate-glandular. Pedicels not jointed (sometimes with abcission layer at bract junction), 5–16 mm, glabrous or pilose and stipitate-glandular; bracts lanceolate to ovate, 1.5–2.5 mm, hairy and glandular on margins. Flowers: hypanthium greenish white, campanulate, 1.8–4 mm, glabrous or scattered-hairy; sepals not overlapping, erect to recurved, greenish, oblong, 1.5–4 mm; petals widely separated, erect, white, obovate, not conspicuously revolute or inrolled, 1–2.5 mm; nectary disc not prominent; stamens as long as or slightly longer than petals; filaments linear, 1–2 mm, glabrous; anthers greenish yellow, oval, 0.4–0.6 mm, apex rounded; ovary setose with eglandular or gland-tipped bristles, sometimes sparsely villous; styles connate to middle or 0.8 mm proximal to stigmas, 4.5–7 mm, villous on proximal 1/2 or glabrous. Berries palatable, greenish to pale red, globose, 7–15 mm, densely bristly or spiny. 2n = 16.
