Abstract
Through the examination of specimens (including type materials), we proved that Cirsium chrysolepis is indistinguishable from C. nishiokae, and C. lipskyi is conspecific with C. interpositum and is the legitimate early name for the species. Therefore, we relegate C. chrysolepis to the synonymy of C. nishiokae and C. interpositum to the synonymy of C. lipskyi.
