根茎短粗，木质化。茎丛生，直立，上部具1-2分枝，密被开展的灰白色糙毛和腺毛。
叶互生，上部偶有对生；托叶披针形，长10毫米，宽2-3毫米，外被柔毛；基生叶和茎下部叶具长柄，柄长为叶片的4-5倍，上部叶柄与叶片近等长，密被开展的腺毛；叶片肾圆形，有时上部叶片五角形，长2.5-3.5厘米，宽4-7厘米，5-7深裂，裂片倒卵状宽楔形，顶部通常向下3裂，小裂片通常具3-4齿状裂片，先端急尖，具不明显尖头，表面被糙伏毛，背面通常仅沿脉被糙毛。
伞花老鹳草 花序伞形状，明显长于叶，通常每3个总花梗簇生分枝先端，似复伞形花序；总花梗密被糙毛和开展的腺毛；花梗与总花梗相似，长为花的2-4倍；萼片卵状椭圆形，长5-6毫米，宽约2毫米，先端具1毫米短尖头，外被开展腺毛；
