Abstract
Paraphlomis qingyuanensis and P. baiwanensis (Lamiaceae), two new species from the limestone area in Guangdong Province, China, are described. Morphologically, both species belong to P. ser. Subcoriaceae C.Y. Wu & H.W. Li. A close relationship between the two new and P. subcoriacea was revealed by molecular phylogenetic analyses based on ETS and ITS. Further morphological and population genetic evidence indicated that they are distinct species in Paraphlomis. According to the IUCN Red List Categories and Criteria, P. qingyuanensis and P. baiwanensis were assessed as Endangered (EN) and Deficient (DD), respectively.
