Rubus multisetosus Yu et Lu, nom. nov. ——R. polytrichus Franch. Pl. Delav. 203. 1890, non Progel 1882.
矮灌木，高达50厘米；枝匍匐生根；枝、叶柄、托叶、叶片下面、花梗和花萼均被黄褐色刺毛和绒毛，或混生腺毛。单叶，叶片心状卵形至近圆形，长3-6厘米，宽2.8-5.5厘米，顶端急尖，基部心形，上面无毛及刺毛，下面密被黄白色绒毛，叶脉突出，沿叶脉具黄褐色.刺毛，边缘3-5浅裂，有细锐重锯齿；叶柄长1.5-3厘米；托叶宿存、离生，卵状披针形或长卵形，长达1.5厘米，宽4-7毫米，羽状浅条裂，下面及边缘具绒毛和刺毛，老时绒毛不脱落。花1至数朵，腋生或成顶生短总状花序；花直径1-2厘米；花梗短；苞片和托叶相似，但较小；萼片披针形，顶端长渐尖，外萼片常条裂，内外两面均密被绒毛，花时直立开展，果期包于果实外面；花瓣宽卵形至长圆形，白色，基部有短爪，外面疏生绒毛，稍短于萼片；雄蕊多数，花丝宽扁，短于花瓣；雌蕊多数，子房光滑无毛。果实近球形，无毛，由多数小核果组成，花柱宿存；核稍具皱纹。花期6-7月，果期8-9月。
产云南西北部。生海拔2500-3000米的山地林中或草地、路旁及山谷水沟边。
本种和三色莓R. tricolor Focke很相近，某些作者曾将这两种合并。根据云南西北部大理苍山及其附近地区所采标本及模式照片观察，刺毛悬钩子的叶片较小，心状卵圆形至近圆形，上面无刺毛，边缘明显3-5裂，有细锐重锯齿，与三色莓仍可区分，故不与合并。
本种和周毛悬钩子R. amphidasys Focke ex Diels比较，区别在于后者托叶早落，叶柄、托叶、叶片两面、花梗和花萼均有长柔毛，也可区别。
形态特征：矮灌木，高达50厘米；枝匍匐生根；枝、叶柄；托叶、叶片下面、花梗和花萼均被黄褐色刺毛和绒毛，或混生腺毛。单叶，叶片心状卵形至近圆形；长3--6厘米；宽2.8--5．5厘米，顶端急尖，基部心形，上面无毛及刺毛，下面密被黄白色绒毛，叶脉突出，沿叶脉具黄褐色刺毛，边缘3—5浅裂，有细锐重锯齿；叶柄长1．5—3厘米；托叶宿存、离生，卵状披针形或长卵形，长达1．5厘米，宽4--7毫米，羽状浅条裂，下面及边缘具绒毛和刺毛，老时绒毛不脱落。花1至数朵，腋生或成顶生短总状花序；花直径1--2厘米；花梗短；苞片和托叶相似，但较小；萼片披针形，顶端长渐尖；外萼片常条裂，内外两面均密被绒毛，花时直立开展，果期包于果实外面；花瓣宽卵形至长圆形，白色，基部有短爪，外面疏生绒毛，稍短于萼 片；雄蕊多数，花丝宽扁，短于花瓣；雌蕊多数，子房光滑无毛。果实近球形，无毛，由多数小核果组成，花柱宿存；核稍具皱纹。花期6—7月；果期8—9月。
产地分布：产云南西北部。生海拔2500—3000米的山地林中或草地、路旁及山谷水沟边。
本种提示：本种和周毛悬钩子R．Amphidasys，Focle ex Diels比较，区别在于后者托叶早落，叶 柏、托叶、叶片两面、花梗和花萼均有长柔毛，也可区别。

刺毛悬钩子 ci mao xuan gou zi
Rubus polytrichus Franchet (1890), not Progel (1882).
Shrubs low, to 50 cm tall, with creeping branches. Branchlets brown to grayish brown, terete, tomentose, yellowish brown bristly or with intermixed stipitate glands. Leaves simple; petiole 1.5–3 cm, tomentose, bristly, or stipitate glandular; stipules persistent, free, ovate-lanceolate or narrowly ovate, 1–1.6 cm × 5–9 mm, abaxially tomentose, bristly, shallowly pinnate-laciniate; blade ovate to suborbicular, 3–6 × 3–5.5 cm, veins raised abaxially, abaxially densely yellowish white tomentose, yellowish brown bristly along veins, adaxially glabrous, base cordate, margin 3–5-lobed, sharply doubly serrulate, apex acute. Inflorescences terminal, short subracemes, 3–5 cm, several flowered, or flowers solitary in leaf axils; bracts ovate-lanceolate or narrowly ovate, 0.8–1.5 cm × 4–8 mm, tomentose when young, bristly, laciniate. Pedicel 5–10 mm. Flowers 1–2 cm in diam. Calyx abaxially tomentose, bristly or stipitate glandular; sepals erect at anthesis, later enclosing fruit, lanceolate, 0.9–1.4 cm × 3.5–6 mm, apex acuminate, outer sepals usually laciniate apically, inner sepals entire. Petals white, broadly ovate to oblong, 7–11 × 5–8 mm, abaxially sparsely tomentose, base shortly clawed. Stamens many, shorter than petals; filaments broad, complanate. Pistils slightly shorter than or nearly as long as stamens; ovary glabrous. Aggregate fruit subglobose, glabrous, with many drupelets and persistent styles; pyrenes slightly rugose. Fl. Jun–Jul, fr. Aug–Sep.
Montane forests and valleys, grasslands, roadsides, near water courses; 2200--3000 m. NW Yunnan.
