Leaves 5–8(–11) cm; stipules 14–25 × 4–9 mm, auricles flared, 3–5 mm, margins undulate, irregularly glandular-serrate, surfaces glabrous, eglandular; petiole and rachis sometimes with pricklets and aciculi, glabrous, puberulent, or sparsely pubescent, stipitate-glandular; leaflets 5–7(–9), terminal: petiolule 6–14 mm, blade narrowly elliptic to ovate, 17–32 × 6–16 mm, membranous, base cuneate, margins 1–2-serrate, teeth 10–18(–23) per side, gland-tipped or eglandular, apex acute, sometimes obtuse, abaxial surfaces pale green, glabrous or pubescent, eglandular, adaxial deep green, turning purplish red in fall, lustrous, glabrous. Inflorescences corymbs, 1–6(–15)-flowered. Pedicels erect, slender to stout, 7–14(–25) mm, glabrous, sparsely to densely stipitate-glandular; bracts 2, broadly lanceolate, 16–25 × 4–6 mm, margins entire, sometimes serrate, gland-tipped, surfaces glabrous with few hairs, eglandular. Flowers 4.3–5.5 cm diam.; hypanthium subglobose or depressed-globose, sometimes globose, 3.5–5.5 × 5.5–6.5 mm, glabrous, stipitate-glandular, neck absent; sepals spreading or reflexed, lanceolate, 20–40 × 2.5–4 mm, tip 6–12 × 0.5–2 mm, margins usually pinnatifid, rarely entire, inner 2 usually entire, abaxial surfaces glabrous, densely stipitate-or setose-glandular; petals single, pink to deep rose, rarely white, 22–26 × 25–30 mm; ?stamens 140?; carpels 26–40(–65), styles exsert 1–2.5 mm beyond stylar orifice (1.5–3 mm diam.) of hypanthial disc (3–5 mm diam.). Hips orange-red to red or red-black, globose to depressed-globose, 8–12 × 9–13 mm, fleshy, glabrous, stipitate-glandular, neck absent; sepals deciduous, erect.
