Rubus grayanus Maxim. in Bull. Acad. Sci. St.. Petersb. 7:152. 1872; Forbes et Hetnsl. in Journ. Linn. Soc. 23: 231. 1887; Focke, Bibl. Bt. 72(2) ; 142. 1911; 0hwi, Fl.Jap. 533. 1965.
形态特征：灌木，高0.5 --2米；小枝棕褐色至紫褐色，具稀疏皮刺或近无刺，无毛。 单叶， 卵形至椭圆形，长了一10厘米，宽3—6厘米，顶端渐尖至尾尖：基部截形至心形， 两面无毛或仅沿叶脉稍有柔毛，下面沿主脉疏生小皮刺；边缘常不分裂；有不整齐粗锐锯齿或重锯齿；叶柄细，长2-3厘米，无毛，疏生小皮刺；托叶小，线形，无毛。花单生于短枝顶端，直径可达2匣米；花梗长1-2.5厘米,无毛，有时具稀疏腺毛；花萼外面无毛或仅于萼片边缘具绒毛；：萼片卵状三角形，长8-14毫米，顶端尾尖,在果期开展或反折；花瓣红色；雄蕊多数，花丝紫红色；雌蕊很多，约100多枚，子房浅紫红色，无毛。果实卵球形，直径，1—1．2匣米，黄。红色，无毛；核具纹孔。花期4月，果期5-6月。
产地分布：产江西、湖南、浙江、福建、广东、广西。 生山坡、 向阳山脊、谷地灌木丛中或溪边水旁杂木林下，海拔500-1100米。：日本<琉球)也有分布。
本种提示：此种和三花悬钩子R．Trianthus Focke 区别在于后者叶片卵状披针形或长圆披针形；花较多，常3朵或超过3朵而于枝顶形成伞房状或短总状花序；雌蕊约10—50，可以区别。

中南悬钩子 zhong nan xuan gou zi
Shrubs 0.5–2 m tall. Branchlets brownish to purplish brown, slightly angled, glabrous, nearly unarmed or with sparse prickles. Leaves simple; petiole 2–3 cm, slender, glabrous, with sparse, minute prickles; stipules linear, 5–7 mm, glabrous; blade ovate to elliptic, 7–10 × 3–6 cm, both surfaces glabrous, or with few soft hairs only along veins, abaxially with sparse, minute prickles along midvein, base truncate to cordate, margin often undivided, sometimes 3–5-lobed, unevenly coarsely sharply serrate to doubly serrate, apex acuminate to caudate. Inflorescences terminal on short branchlets, 1-flowered. Pedicel 1–2.5 cm, glabrous, occasionally with sparse, glandular hairs. Flowers to 2 cm in diam. Calyx abaxially glabrous; tube pelviform; sepals spreading or reflexed in fruit, ovate-triangular, 0.8–1.4 cm × 3–5 mm, margin tomentose, apex caudate. Petals red, 0.8–1.4 cm in diam., nearly as long as or slightly longer than sepals, glabrous, base shortly clawed. Stamens many; filaments and anthers purplish red. Pistils numerous, more than 100, shorter than stamens; ovary purplish red, glabrous; styles glabrous. Aggregate fruit yellowish red, ovoid-globose, 1–1.2 cm in diam., glabrous; pyrenes reniform, small, foveolate. Fl. Apr–May, fr. Jun–Jul. 2n = 14.
Slopes, sunny areas, montane valleys, thickets, mixed forests along water courses; 300--1100 m. Fujian, Guangdong, Guangxi, Hunan, Jiangxi, Zhejiang [Japan].
