灌木，高约1米；小枝灰褐色，圆柱形，具棕黄色柔毛、软刺毛、稀疏钩状小皮刺及腺毛。单叶，长卵形或宽长圆形，长7-13厘米，宽5-8厘米，顶端急尖，基部深心形，两面沿叶脉具柔毛、软刺毛和稀疏钩状小皮刺，边缘不分裂或微波状，密被细锐锯齿，侧脉5-6对；叶柄长2-3厘米，具柔毛、软刺毛和稀疏钩状小皮刺及腺毛；托叶离生，棕褐色，长达1厘米，有柔毛和软刺毛，羽状深条裂，裂片线形。花成近总状或狭圆锥状花序，顶生或腋生，具少数花朵；总花梗和花梗均密被柔毛，稀疏软刺毛和腺毛；花梗长1-1.5厘米；苞，片与托叶相似；花直径1-1.5厘米；花萼外密被黄棕色软刺毛、柔、毛和疏腺毛；萼片卵状披针形，顶端尾尖，外萼片顶端常条裂；花瓣近圆形，边缘圆锯齿状，基部具短爪，内面近基部具柔毛；雄蕊较短，花丝宽扁，无毛；雌蕊约40或稍多，花柱长于雄蕊，子房具柔毛。果实红色。
产云南南部。生低海拔的山地荒野。
此种和黄穗悬钩子R. chrysobotrys Hand. -Mazz.比较近似，区别在于后者枝、叶柄和花序均被黄色长柔毛。无软刺毛及腺毛；叶片宽卵形，下面幼时具黄色绒毛，老时脱落；托叶和苞片分裂较浅；花序较长大而多花；雌蕊无毛，易于区别。

Shrubs ca. 1 m tall. Branchlets grayish brown or reddish brown, cylindric, brownish yellow pubescent, soft bristly, with sparse, curved minute prickles and glandular hairs; petiole 2–3 cm, pubescent, soft bristly, with sparse, curved minute prickles and glandular hairs; stipules free, brownish, to 1 cm, pubescent, soft bristly, deeply pinnate-laciniate; lobes linear; blade narrowly ovate or broadly oblong, 7–13 × 5–8 cm, lateral veins 5 or 6 pairs, both surfaces pubescent, soft bristly, with sparse, curved minute prickles along veins, base deeply cordate, margin undivided or somewhat undulate, densely thin sharply serrate, apex acute. Inflorescences terminal or axillary, subracemes or narrow panicles, 6–10 cm, few flowered; rachis and pedicels densely pubescent, sparsely soft bristly, with glandular hairs; bracts less than 1 cm, pubescent, soft bristly, deeply pinnate-laciniate; lobes linear. Pedicel 1–1.5 cm. Flowers 1–1.5 cm in diam. Calyx densely brownish yellow soft bristly, pubescent, with sparse, intermixed glandular hairs; tube pelviform; sepals ovate-lanceolate, 6–8 × 3–5 mm, apex caudate; outer sepals apically often shallowly laciniate. Petals suborbicular, 5–6 mm in diam., shorter than sepals, adaxially puberulous, base shortly clawed, margin crenate. Stamens many, shorter than petals; filaments broad, complanate, glabrous.
