Plants 0.7–1.5 m. Stems spreading or decumbent, copiously pubescent, puberulent, and stipitate-glandular; spines at nodes 1–5, (1.5–)4–6(–10) mm; prickles on internodes sparse to dense. Leaves: petiole 0.7–4(–5) cm, pubescent, stipitate-glandular; blade pentagonal, irregularly 5-lobed, cleft 2/3–3/4 to midrib, (0.5–)1–3.5(–4) cm, base cordate, surfaces densely pubescent or stipitate-glandular, lobes cuneate-rounded, margins irregularly serrate, toothed apex somewhat acute. Inflorescences pendent, 3–8(–11)-flowered racemes, 2–3 cm, axis puberulent, stipitate-glandular, flowers evenly spaced. Pedicels jointed, 1–4(–5) mm, puberulent, stipitate-glandular; bracts lanceolate-ovate, 1.3–3 mm, puberulent, stipitate-glandular. Flowers: hypanthium pinkish to orangish, saucer-shaped, 0.5–1.5 mm, pubescent and stipitate-glandular abaxially, glabrous adaxially; sepals separated, spreading, green to yellowish, pink, red, orange, or white, sometimes with pale yellow, scarious margins, broadly ovate to obovate, 2.5–4 mm; petals widely separated, erect, red, pinkish, or purplish, cuneate-lunate, not conspicuously revolute or inrolled, 0.9–1.5 mm; nectary disc yellowish, pinkish, or red, flat, 5-angled, covering most of ovary; stamens as long as petals; filaments linear, (0.5–)0.9–1.6 mm, glabrous; anthers yellow or cream, oblate to transversely elliptic, 0.5–0.8 mm, broader than long, apex notched; ovary sparsely to thickly, usually purplish glandular-bristly; styles connate ca. 4/5 their lengths, 1.1–1.8 mm, glabrous. Berries somewhat palatable, bright red, obovoid-spheric, 5–10 mm, glandular-bristly.
