Subshrubs, forming open colonies. Stems erect, 1–8(–15) dm, openly branched; bark dark reddish brown, glabrous; infrastipular prickles single or paired, erect, subulate, 3–10 × 0.5–1.5 mm, ?base glabrous?, internodal prickles dense, smaller, sometimes mixed with aciculi. Leaves (2–)3.5–7(–8.5) cm; stipules 5–10(–30) × 2–5 mm, auricles slightly flared, 1–3 mm, margins entire, sometimes stipitate-glandular, surfaces glabrous, eglandular; petiole and rachis usually with pricklets, glabrous or finely hairy, stipitate-glandular; leaflets 5(–7), terminal: petiolule 5–12 mm, blade ± elliptic, 12–25(–32) × 6–15(–20) mm, membranous to ± leathery, base rounded, sometimes obtuse to cuneate, margins multi-serrate to nearly 1-serrate, teeth (5–)7–12 per side, acute to obtuse, usually gland-tipped, apex obtuse to rounded, abaxial surfaces ± pale green, glabrous or sparsely hairy, glandular, adaxial green, dull, glabrous. Inflorescences corymbs, 1–5(+)-flowered. Pedicels erect, mostly slender, 2–20(–35) mm, glabrous or sparsely hairy, sometimes stipitate-glandular; bracts 1–3, lanceolate or ovate-lanceolate, 6–25 × 2–7 mm, margins entire or serrate, short stipitate-glandular, surfaces glabrous or sparsely pubescent, glandular. Flowers 2–4 cm diam.; hypanthium ovoid to depressed-globose, 3.5–4 × 3.5–4 mm, glabrous, eglandular, neck 0.5 × 2.5–3.5 mm; sepals spreading to reflexed, ovate-lanceolate, 7–12 × 3 mm, tip 2–8 × 0.5–2 mm, margins entire or slightly toothed, abaxial surfaces finely hairy, stipitate-glandular, sometimes eglandular; petals single, deep pink, 10–20 × 10–20 mm; carpels 10–40, styles exsert 1.5 mm beyond stylar orifice (1.5–2 mm diam.) of hypanthial disc (3.5–5 mm diam.). Hips scarlet, subglobose to ovoid, 10 × 10–12 mm, fleshy, glabrous, eglandular, neck 1 × 4–5 mm; sepals persistent, erect. Achenes basiparietal, 1–10, pale tan, 3–4 × 2.5–3 mm. 2n = 14.
