形态特征：灌木，高3--5米；小枝圆柱形，无毛或有稀疏短柔毛；有直立或稍弯曲，基部膨大而扁 平皮刺，有时老枝常混有针刺。小叶7--11，连叶柄长6--11厘米；小叶片椭圆形至卵状长 圆形，长2—5厘米，宽8—20毫米，先端急尖稀圆钝，基部近圆形或宽楔形；边缘有重局 齿，上面无毛，下面有柔毛或至少沿脉有柔毛，中脉和侧脉均突起；小叶柄和叶丑柔毛、 腺毛和散生小皮刺；托叶大部贴生于叶柄，寓生部分卵状披针形，先端渐尖；边缘有腺齿。 花单生，或2—3朵簇生，苞片1—2，卵状披针形，先端尾尖，下面中脉明显，边缘有带腺锯 齿，有时有羽状裂片；花梗长1．5—2厘米，有腺毛；花直径3—5厘米；萼片卵状披针形，先 端浅裂扩展成叶状，或有时羽状分裂，外面近无毛，有腺或无腺，内面有短柔毛，边缘较密； 花瓣粉红色，宽倒卵形，先端微凹，基部宽楔形；花柱离生。密被柔毛，比雄蕊短很多。果长 圆形或倒卵状长圆形，先端有短颈，长1．5—2．5厘米，宽1--1.7厘米，紫红色，外面常有腺 毛，萼片直立宿存。花期6--7月，果期8—11月。
产地分布：产云南、四川、湖北、陕西、甘肃、青海、西藏等省区。生山坡路旁或灌丛中，梅拔 2300—3850米。模式标本采自甘肃。
本种提示：本种叶片边缘有重锯齿与刺毛蔷薇R．Setipoda Hemsl．Et Wils．相近似，但后者一般 皮刺较少，叶片较大，叶片下面柔毛较少，常有腺体，花序伞房状有多朵花，萼片先端常有 羽状裂片，花瓣外面被柔毛，可以区别。

Shrubs 3–5 m tall. Branchlets terete, glabrous or sparsely puberulous, prickly; prickles paired below leaves, sometimes scattered, straight or slightly curved, to 1.5 cm, stout, flat, gradually tapering to broad base, sometimes intermixed with smaller prickles and bristles, old branches sometimes intermixed with bristles. Leaves including petiole 6–11 cm; stipules mostly adnate to petiole, free parts ovate-lanceolate, margin glandular serrate, apex acuminate; rachis and petiole pubescent, glandular-pubescent, sparsely shortly prickly; leaflets 7–11, elliptic or ovate-oblong, 2–5 × 0.8–2 cm, abaxially pubescent or glandular, with prominent midvein and lateral veins, adaxially glabrous, base subrounded or broadly cuneate, margin doubly serrate, apex acute, rarely rounded-obtuse. Flowers solitary, or 2 or 3 and fasciculate, 3–5 cm in diam.; pedicel 1.5–3 cm; bracts 1 or 2, ovate-lanceolate, abaxially with distinct midvein, margin glandular serrate, sometimes pinnately lobed, apex caudate. Hypanthium oblong or obovoid, often stipitate glandular. Sepals 5, ovate-lanceolate, leaflike, abaxially subglabrous, stipitate glandular or not, adaxially puberulous, margin sometimes pinnately lobed. Petals 5, pink, broadly obovate, base broadly cuneate, apex emarginate. Styles free, much shorter than stamens, densely pubescent.
