Shrubs, forming thickets or not. Stems erect to deflexed, 3–6 dm, densely branched; bark dull reddish brown, sometimes green, glabrous; infrastipular prickles paired, erect, subulate, 2–5 × 0.5–1 mm, ?base glabrous?, internodal prickles or aciculi rare, sometimes absent. Leaves 3–7 cm; stipules 6–14 × 1.5–4 mm, auricles flared, 2–3 mm, margins entire or glandular-serrate, eglandular, surfaces glabrous, rarely puberulent, eglandular; petiole and rachis with pricklets, usually glabrous, stipitate-glandular; leaflets (5–)9(–11), terminal: petiolule 1–4(–6) mm, blade lanceolate to narrowly elliptic, 14–25 × 3–7 mm, membranous, base long-cuneate, margins 1-serrate, ?gland-tipped or eglandular?, teeth 9–15 per side, gland-tipped, apex acute, abaxial surfaces light green, glabrous, eglandular, ?exserted midveins sometimes with sparse pricklets, pubescent, stipitate-glandular?, adaxial deep green, lustrous, glabrous. Inflorescences corymbs, 1(–5)-flowered. Pedicels erect, slender, 2–8 mm, glabrous, stipitate-glandular; bracts 2, lanceolate, 8–12 × 3–4 mm, margins entire, few stipitate-glandular, surfaces glabrous, eglandular. Flowers 3.5–4.5 cm diam.; hypanthium subglobose, globose, or ovoid, 4–4.5 × 2.5–4 mm, glabrous, usually densely stipitate-glandular, neck absent; sepals reflexed or spreading, lanceolate, 13–20 × 2–3 mm, tip 3 × 0.5 mm, margins pinnatifid, abaxial surfaces glabrous or puberulent, stipitate-glandular; petals single, white, rarely pink, 17–28 × (6–)10–18 mm; carpels 20–32, styles exsert 1–1.5 mm beyond stylar orifice (1.5–2 mm diam.) of hypanthial disc (3–4 mm diam.). Hips dull red, globose to depressed-globose, rarely urceolate, 9–10 × 7–9 mm, leathery, glabrous, densely stipitate-glandular, neck absent or insignificant; sepals deciduous, spreading to erect.
