形态特征:罐木,高1.5--2.5米;枝拱曲,红褐色,有时被白粉,疏生紫红色钩状扁平皮刺,幼枝被短柔毛。小叶5--7枚,卵形、卵状披针形或卵状长圆形,顶生小叶有时为菱状披针形,长3--7厘米,宽1.5--4厘米,顶端渐尖,基部宽楔形至圆形,上面无毛或近无毛,下面被灰白色绒毛,边缘具粗重锯齿,有时找裂;叶柄长3一5厘米,顶生小叶柄长1--2厘米,侧生小叶几无柄,与叶轴均被柔毛和钩状小皮刺;托叶小,线形,长约,毫米,有柔毛。顶生花序为狭圆锥花序,侧生者为总状花序,花梗和苞片均桩柔毛;花梗细,长5--8毫米;苞片小,线状披针形;花直径5--8毫米;花萼外密被灰白色绒毛;萼片卵形至长卵形,长3--6毫米,顶端急尖而有突尖头,在花果时均直立开展;花瓣近圆形,基部具短爪,粉红色,与萼片几等长或稍长;雄蕊多数,花药紫色,花丝线形;花柱无毛,于房具柔毛。果实球形,直径5—日毫米,红色至红黑色,无毛或微具柔毛;小核卯球形,多皱。 花期6--7月,果期8--9月。
用    途:果较小,甜酸可食,也可供制醋。
产地分布:产河南,山西、陕西、甘肃、湖北、四川、西藏。 生于海拔900--2600米的山谷河旁、沟边或山坡杂木丛中。
本种提示:Focke据云南地区标本发表R.flosculosus Focke subsp·mairelFocke,BiN.Bot.83:45.1914 ln obs non leel.1912 nec Lelv.19130据记载,花白色,开花后花萼直径约12毫米,产云南东川,海拔2600米。我们整理了历年来所采大量云南省标本,并未发现弓茎悬钩子在云南有分布,而仅见到华中悬钩子R.Cockburnlanus Hemsl.的标本。华中悬钩子的花较弓茎悬钩子稍大,由此推测R.Flosculosns Focke subsp.mairei Focke是华中悬钩子的异名。
