Abstract
Thalictrum xingshanicum was considered to be different from its close ally T. fargesii by the leaf size and number of carpels. In the present study, it reveals that morphological variation of T. fargesii had been misunderstood by previous authors. Here, we clarify the variations of T. fargesii and propose T. xingshanicum as its new synonym. A lectotype of T. pallidum Franch. is also designated.
