多年生草本，根状茎短，有多数纤维状根，全株被薄蛛丝状白色绵毛。早春从根状茎长出花茎，近雌雄异株；雌株花茎高27-60厘米，具鳞片状叶；苞叶卵状披针形，长3-4厘米，基生叶具长柄，叶片宽肾状心形，长2-8厘米，边缘有细齿，齿端具软骨质小尖，叶脉掌状两面被白色绵毛，或后多少脱毛；雌头状花序在花茎顶端排成密集的聚伞状圆锥花序，直径8-12毫米；花序梗长1-2.5厘米，有1或数枚披针形苞叶；总苞钟状；总苞片1层，10-12个，披针形，或披针状长圆形，长约7毫米，外面有小苞片雌花花冠顶端4-5撕裂，裂片不等长，丝状或钻形；花柱伸出花冠；柱头2裂；雄头状花序在花茎端排成伞房状或圆锥状，花冠管状，裂片披针形；花柱伸出花冠外，柱头头状，略分枝，瘦果圆柱形，无毛；雌花的冠毛丰富，白色；雄花的冠毛较少，短于花冠。
产山西、陕西、甘肃、青海、云南、四川、贵州、西藏。常生于山谷路旁或水旁，海拔700-4200米。尼泊尔、印度和越南也有分布。模式标本采自陕西秦岭，山西分布新记录。
全草入药，功效与蜂斗菜相同。
J. Toman（1972）曾将特产于我国台湾的台湾蜂斗菜合并于本种，作为本种的异名，但后者的总苞较短，雌花序的总苞钟状，直径10-14毫米；花柱明显伸出花冠，显然有别于本种。
