  多年生根状茎草本,具茎叶,稀近葶状。茎单生,直立,高40-80厘米,不分枝或有花序枝,被疏蛛丝状毛,或变无毛。基生叶在花期生存或凋落。基生叶和最下部茎叶具柄,全形卵状椭圆形,卵状披针形至倒披针形,长8-10(-20)厘米,宽3-7厘米,顶端钝,基部微心形至楔状狭,具齿,不分裂或大头羽状分裂,侧裂片1-4对,向叶基部小,纸质,上面无毛,下面有疏蛛丝状毛,或多少变无毛,羽状脉,侧脉8-9对;叶柄长达10厘米,基部扩大;中部茎叶全形长圆形或倒披针状长圆形,长5-22厘米,宽2-7厘米,大头羽状浅裂或羽状浅裂,裂片多变异,顶生裂片大至小,卵形至长圆状披针形,具齿或细裂,侧裂片5-8对,长圆形至狭长圆状披针形,全缘或通常有不规则锯齿状齿或细裂,开展或稍上升,基部具耳;耳具齿或细裂,半抱茎;上部叶渐小,长圆状披针形或长圆状线形,具粗羽状齿。头状花序有舌状花,多数,排列成顶生伞房花序或复伞房花序;花序梗长5-25毫米,或多或少被蛛丝状绒毛或黄褐色短柔毛,或变无毛,有线形苞片和2-3线状钻形小苞片。总苞钟状,长3-4毫米,宽3-4毫米,具外层苞片;苞片8-10,线状钻形,长2-3毫米;总苞片10-13,长圆状披针形,渐尖,上端黑褐色,有柔毛,草质,边缘宽干膜质,向基部有黄褐色短柔毛。舌状花10-13,管部长2.5毫米;舌片黄色,长圆形,长约6.5毫米,宽2毫米,钝,上端具3细齿,有4脉;管状花多数,花冠黄色,长5-5.5毫米,管部长2.5毫米,檐部漏斗状;裂片卵状三角形,长0.8毫米,尖;花药长2毫米,基部具钝耳;附片卵状披针形;花药颈部稍伸长,向基部稍膨大。花柱分枝长1毫米,顶端截形,有乳头状毛。瘦果圆柱形,全部或管状花的瘦果有疏柔毛,有时舌状花的或全部小花的瘦果无毛。冠毛长约4毫米,污白色,禾杆色或稀淡红色,冠毛在全部瘦果存在,或有时舌状花的瘦果无冠毛;或脱落。花期4-11月。
  产西藏(珠穆朗玛峰北坡、聂拉木)、重庆(綦江)、贵州(平坝、罗福、安顺、清镇、遵义、威宁、纳拥)、湖北(宜昌)、湖南(洞庭湖附近)、云南(腾冲、澜沧江一怒江分水岭、维西、丽江、澜沧、中甸、大理、顺宁、思茅、昆明、巧家、东川、蒙自、屏边)。生于林下、林缘、开旷草坡、田边和路边,海拔1 100-3750米。巴基斯坦、印度、尼泊尔和不丹也有。模式采自印度库盟。
  本种自巴基斯坦西北部、印度西北和东北部至中国西南部及中部有广泛的分布。体态、叶形、瘦果的毛被、冠毛的颜色等方面多变异。舌状花瘦果具少数淡红色冠毛或无冠毛,与莱菔叶千里光S. raphanifolius Wall. ex DC.往往难以区别。此两种居群间的关系有待野外观察和研究。
