低矮半灌木，高40-60厘米；茎木质，单一，直立，无毛，稀微具柔毛，有稀疏钩状短小皮刺，花枝自匍匐根上长出。小叶3枚，卵形至卵状披针形，长6-9.5厘米，宽2.5-5厘米，顶生小叶稍长于侧生者，顶端渐尖，基部近圆形，上面具稀疏糙柔毛，下面仅沿叶脉有疏柔毛或具极疏小皮刺，边缘有不整齐尖锐锯齿；叶柄长5-10厘米，顶生小叶柄长达1 厘米，侧生小叶几无柄或具极短柄，微被柔毛和钩状小皮刺；托叶基部与叶柄连生，线状披针形，全缘。花2-4朵腋生或顶生，稀单生；花梗长0.6-1.2厘米，具稀疏柔毛和钩状小皮刺；花直径1.5-2厘米；花萼外有稀疏钩状小皮刺和细柔毛；萼片长三角形至卵圆形，顶端钻状长渐尖，外面边缘及内面被绒毛；花瓣倒卵圆形，白色，被细柔毛，具短爪，几与萼片等长；雄蕊多数，直立，花丝宽扁；雌蕊多数，子房顶端及花柱基部具柔毛。果实桔红色，球形，常无毛，小核果多数；核具皱纹。花期5-6月，果期8-9月。
产陕西、甘肃、湖北、江苏、四川。生山坡、路边或林中，海拔1500-2500米。
Focke把本种归入匍匐莓组Sect. Cylactis Focke,但其托叶与叶柄合生，列入空心莓组Sect. Idaeobatus Focke较为合适。

Rubus simplex Focke
单茎悬钩子 dan jing xuan gou zi
Subshrubs low, 40–60 cm tall. Stems erect, brownish, woody, not branched, glabrous, rarely puberulous, with sparse, short curved prickles; flower bearing branchlets arising from creeping roots. Leaves imparipinnate, 3-foliolate; petiole 5–10 cm, petiolule of terminal leaflet to 1 cm; lateral leaflets subsessile or shortly petiolulate, puberulous, with sparse, curved prickles; stipules lanceolate or linear-lanceolate, 6–9 mm, puberulent, margin entire; blade of leaflets ovate to ovate-lanceolate, 6–9.5 × 2.5–5 cm, terminal leaflet slightly longer than lateral leaflets, abaxially pilose or with sparse, minute prickles only along veins, adaxially sparsely appressed pubescent, base subrounded, margin irregularly shortly serrate, apex acuminate. Inflorescences terminal or axillary, 3- or 4-flowered, rarely flowers solitary; bracts linear to lanceolate, 5–9 mm, puberulous. Pedicel 6–12 mm, puberulous, with curved minute prickles. Flowers 1.5–2 cm in diam. Calyx abaxially with sparse, curved minute prickles, finely pubescent; sepals narrowly triangular to ovate, 6–10 × 3–5 mm, margin tomentose, apex subulate-acuminate. Petals white, obovate, 4–6 mm in diam., nearly as long as sepals, finely pubescent, base shortly clawed. Stamens many, erect, shorter than petals; filaments broad, complanate. Pistils slightly shorter than stamens; apex of ovary and base of style pubescent. Aggregate fruit orange-red, globose, 7–9 mm in diam., often glabrous, with many drupelets; pyrenes rugose. Fl.
