Stems usually erect to sprawling, 10–25(–50) dm; distal branches arching, bark green; infrastipular prickles paired, curved or appressed, 6–7 × 4–9 mm, lengths ± uniform, internodal prickles rare, single, rarely absent. Leaves deciduous, 6–11 cm; stipules 10–22 × 3–5 mm, auricles 3–5 mm, margins stipitate-glandular or eglandular, surfaces glabrous, eglandular or sparsely stipitate-glandular; petiole and rachis sometimes with pricklets, glabrous, eglandular; leaflets 5–7, terminal: petiolule 5–11 mm, blade ovate, obovate, or elliptic, 15–40 × 12–20 mm, base obtuse to slightly cuneate, margins 1- or multi-serrate, teeth 20–30 per side, apex acute, sometimes acuminate, abaxial surfaces glabrous, rarely pubescent or tomentose on midveins, eglandular, adaxial dark green to green, lustrous to dull, glabrous, rarely tomentose. Inflorescences panicles, sometimes corymbs, solitary, sometimes 2 or 3(–7)-flowered. Pedicels erect to reflexed as hips mature, 8–20 mm, eglandular or stipitate-glandular; bracts 2, ovate-lanceolate, 6–18 × 4–5 mm, margins glandular-serrate, abaxial surfaces puberulent, adaxial surfaces glabrous, eglandular. Flowers 3.5–5 cm diam.; hypanthium narrowly urceolate, 7–9 × 3–6 mm, eglandular, neck 2–3 × 1–2 mm; sepals appressed-reflexed, spreading, or erect, ovate-lanceolate, 10–17 × 3–5 mm, margins deeply pinnatifid, tip 4–6 × 0.5 mm, abaxially eglandular; petals rose, pink, or white, sweet-scented, 18–25 × 15–18 mm; carpels 26–36, styles villous, exsert 1–2 mm beyond stylar orifice (0.7–1.5 mm diam.) of hypanthial disc (4–5 mm diam.). Hips red, globose, ovoid, urceolate, or ellipsoid, 10–16(–24) × 6–16 mm, glabrous, eglandular; sepals deciduous as hips mature, reflexed. Achenes 14–23, tan, 5–6 × 3–3.5 mm. 2n = 35.
