ABSTRACT

Petrocodon scopulorum (Chun) Y.Z. Wang is a rare plant endemic to China. However, it has never been found inthe “Pingfa” area of Guizhou province, the type locality of Pet. 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 ofPet. scopulorum. In this study, the morphology and molecular analyses as well as textual analyses of protologue confirmedthat the type locality of Pet. scopulorum was “Pingba”, Anshun City. while the type locality recorded in Flora ReipublicaePopularis Sinicae is an incorrect translation of the original record of the type specimen. The results here provide a correct typelocality records and also a reliable basis for the identification, conservation and research of the Pet. scopulorum.
