Neotypification of Veronica pusanensis (Scrophulariaceae)

A type specimen is the specimen originally used to name a new species; thus, it is one of the most significant materials for taxonomic study. In our study on the inventory and management of endemic species in Korea, we checked the type materials for Pseudolysimachion pusanensis (Y. Lee) Y. Lee, combination name Veronica pusanensis Y. Lee, recorded as deposited at the herbaria of the Ewha Womans University and the National Institute of Biological Resources, and failed to find any specimens. Thus, we concluded that all type specimens of V. pusanensis have since been misplaced. According to articles 9.11 and 9.13 of the International Code of Nomenclature for algae, fungi, and plants, it is necessary to select a neotype if the holotype is missing and no other original material exists. Therefore, we designate the neotype maintained in the herbarium of the National Institute of Biological Resources of the Republic of Korea.
