多年生草本。根茎纺锤形，棕褐色。茎1-2，高25-40厘米，不分枝或茎中上部有1-2个分枝。基生叶有柄，叶柄长3-7厘米，叶片三出分裂，裂片扇形，中下部3深裂，边缘有缺刻状锯齿，或近于三出式的2回羽状分裂，裂片披针形；茎生叶1-2回三出分裂，无柄或有短柄，裂片线形伸长。复伞形花序顶生或侧生，无总苞；伞辐7-24，开展，长2-4厘米；小总苞片2-3个；小伞形花序有花2-3；萼齿细小；花柱和花柱基短缩。果实长卵形，长约3毫米，宽约1毫米；每棱槽中油管1-2。
产湖北、四川、陕西、甘肃、青海。生于海拔1500-3000米林下。模式标本采自湖北宜昌。
本种茎生叶与基生叶的叶形及分裂形式，细小的萼齿，短缩的花柱基及花柱，与东亚囊瓣芹 P. tanakae (Franch. et Sav.) Hand. -Mazz. 相近，但本种的植株较高大，高25-40厘米，有1-2分枝，果实稍大，长可达3毫米，可以区别。
本种与异叶囊瓣芹 P. heterophyllum Hand. -Mazz. 的区别，主要是后者伞辐较短，仅1-2厘米长，果实卵形，萼齿明显，花柱基圆锥形，花柱伸长。
