Shrubs small, ca. 1 m tall, dense. Branchlets dense, dark purple-red, prickles paired below each node and densely scattered, terete, straight, bristlelike, to 6 mm, fine, abruptly flaring to an elliptic base; branches of present year sparsely prickly. Leaves including petiole 4–7 cm; stipules mostly adnate to petiole, free parts ovate-lanceolate, glabrous, margin glandular serrate; rachis and petiole sparsely prickly and glandular; leaflets 7–11(–15), elliptic, obovate-elliptic, or oblong-elliptic, 6–15 × 4–8 mm, abaxially subglabrous or along veins sparsely pubescent, rarely sparsely glandular, adaxially glabrous, base subrounded or broadly cuneate, margin acutely glandular serrate, partly doubly serrate, apex rounded-obtuse. Flower solitary, axillary, 2–3 cm in diam.; pedicel 1.2–2 cm, glandular-pubescent; bracts absent. Hypanthium oblong. Sepals 5, lanceolate, abaxially glabrous, adaxially sparsely pubescent, not glandular, rarely sparsely glandular at margin, apex long acuminate or caudate-acuminate. Petals 5, tinged with pinkish, obovate, base cuneate, apex emarginate. Styles free, much shorter than stamens, slightly exserted. Hip orange-red, oblong, 1.5–2 cm, shiny, with persistent, erect sepals; pedicel 1.2–2 cm, glandular-pubescent. Fl. May–Jun, Jul–Sep.
Forests margins, scrub, rocky places on slopes; 600--1200 m. Heilongjiang, Jilin, Liaoning [Korea].
