摘　　要：世纬苣苔是中国特有珍稀植物,但在《中国植物志》记载的模式产地贵州省"平伐"从未找到过该植物。模式产地考证信息的缺失,会在世纬苣苔的鉴定和相关科学研究中产生一定的混乱。作者从产地记载、标本形态、分子证据三个方面进行了考证,确认了世纬苣苔模式产地是贵州省"平坝"(安顺市),而《中国植物志》所记载的模式产地是对模式标本原始记录的错误翻译。考证结果提供了正确的模式产地,使世纬苣苔的鉴定、保护、研究具有了切实可靠的依据。Petrocodon scopulorum( Chun) Y. Z. Wang is a rare plant endemic to China. However,it has never been found in the "Pingfa" area of Guizhou Province,the type locality of P. scopulorum recorded in Flora Reipublicae Popularis Sinicae. The lack of textual information of the type locality will inevitably brings chaos to the identification and related research of P. scopulorum. In this study,the morphology and molecular analyses as well as textual analyses of protologue confirmed that the type locality of P. scopulorum was"Pingba",Anshun City. While the type locality recorded in Flora Reipublicae Popularis Sinicae is an incorrect translation of the original record of the type specimen. The results here provide a correct type locality record and also a reliable basis for the identification,conservation and research of the P. scopulorum.
