攀援灌木，高1-2米；.枝圆柱形，棕褐色，密被红褐色长短不等的腺毛、刺毛和长柔毛，疏生基部增宽的小皮刺。单叶，近圆形，直径10-20厘米，长几与宽相等，顶端短渐尖，基部心形，两面均被柔毛，沿叶脉具红褐色腺毛和刺毛，边缘3-5裂，裂片三角形，顶端急尖至短渐尖，顶生裂片比侧生者稍大，有不整齐锐锯齿，基部具掌状5出脉，侧脉4-5对；叶柄长4-8厘米，具紫红色腺毛、刺毛和柔毛；托叶离生，长1-1.5厘米，褐色，具长柔毛和腺毛，掌状深裂，裂片披针形或线状披针形，脱落。花成大型圆锥花序，顶生或腋生，腋生花序通常较小，狭圆锥形或近总状；总花梗、花梗和花萼均密被红褐色腺毛、刺毛和长柔毛；花梗长0.8-1.5厘米；苞片与托叶相似，位于花序顶部者稍狭小；花直径1-1.5厘米；萼片狭披针形，长1-1.5厘米，顶端尾尖，边缘稍具绒毛，外萼片边缘常浅条裂，裂片线形，在果期常直立；花瓣宽倒卵形，白色，基部具爪，短于萼片；雄蕊多数，花丝线形，花药具长柔毛；花柱长于雄蕊，子房无毛。果实近球形，直径约1厘米，红色、无毛，包藏在宿萼内；核稍具皱纹。花期6-7月，果期8-9月。
产广东、广西。生低海拔至中海拔的山地路旁或山谷灌丛中。
此种和周毛悬钩子R. amphidasys Focke ex Diels相近，区别在于后者为蔓性小灌木；叶片宽长卵形，边缘裂片小而圆钝，顶生裂片比侧生者大数倍；花常5-12朵形成近总状花序或3-5朵簇生于叶腋。
形态特征：攀援灌木，高1—2米；枝圆柱形，棕褐色，密被红褐色长短不等的腺毛、刺毛和长柔毛，疏生基部增宽的小皮刺。单叶，近圆形，直径10一20厘米，长几与宽相等，顶端短渐尖，基部心形，两面均被柔毛，沿叶脉具红褐色腺毛和刺毛，边缘3—5裂，裂片三角形，顶端急尖至短渐尖，顶生裂片比侧生者稍大，有不整齐锐锯齿，基部具掌状5出脉，侧脉4—5对；叶柄长4—8厘米，具紫红色腺毛、刺毛和柔毛；托叶离生，长1—1．5厘米，褐色，具长柔毛和腺毛，掌状深裂，裂片披针形或线状披针形，脱落。花成大型圆锥花序，顶生或腋生，腋生花序通常较小，狭圆锥形或近总状；总花梗、花梗和花萼均密被红褐色腺毛、刺毛和长柔毛；花梗长0．8—1．5厘米；苞片与托叶相似，位于花序顶部者稍狭小；花直径1—1．5厘米；萼片狭披针形，长1—1．5厘米，顶端尾尖，边缘稍具绒毛，外萼片边缘常浅条裂，裂片线形，在果期常直立；花瓣宽倒卵形，白色，基部具爪，短于萼片；雄蕊多数，花丝线形，花药具·长柔毛；花柱长于雄蕊，子房无毛。-果实近球形，直径约1厘米，红色、无毛，包藏在宿萼 内；核梢具皱纹。 花期6—7月，果期8—9月。
产地分布：产广东、广西。生低海拔至中海拔的山地路旁或山谷灌丛中。
本种提示：此种和周毛悬钩子R．Amphidasys Focke cx Diels相近，区别在于后者为蔓性小灌木； 叶片宽长卵形，边缘裂片小而圆钝，顶生裂片比侧生者大数倍；花常5—12朵形成近总状 花序或3一5弓朵簇生于叶腋。

Shrubs scandent, 1–2 m tall. Branchlets brownish, terete, densely villous, bristly, unevenly glandular hairy, with sparse, small basally broad prickles. Leaves simple; petiole 4–8 cm, with reddish purple glandular hairs, bristly, villous; stipules caducous, free, brown, 1–1.5 cm, villous, with glandular hairs, palmatipartite; lobes lanceolate or linear-lanceolate; blade suborbicular, 10–20 cm in diam. and ca. as long, palmately 5-veined, lateral veins 4 or 5 pairs, both surfaces soft hairy, with reddish brown glandular hairs and bristles along veins, base cordate, margin 3–5-lobed; lobes triangular, terminal lobe slightly larger than lateral lobes, irregularly sharply serrate, apex acute to shortly acuminate. Inflorescences terminal or axillary, terminal ones cymose panicles, large, to 20 cm, axillary ones narrow panicles or subracemes, shorter; rachis, pedicels, and abaxial surface of calyx with dense reddish brown glandular hairs, bristles and long hairs; bracts 1–1.4 cm, villous, with glandular hairs, palmatipartite; lobes lanceolate or linear-lanceolate. Pedicel 0.8–1.5 cm. Flowers 1–1.5 cm in diam. Sepals erect in fruit, narrowly lanceolate, 1–1.5 cm, margin slightly tomentose, apex caudate, outer sepals often shallowly laciniate; lobes linear. Petals white, broadly obovate, shorter than sepals, base clawed. Stamens many; filaments linear; anthers villous. Ovary glabrous; styles longer than stamens. Aggregate fruit subglobose, red, ca. 1 cm in diam., glabrous, enclosed in calyx; pyrenes slightly rugose. Fl. Jun–Jul, fr. Aug–Sep.
