摘要： Oreocharis oriolus, a new species of Gesneriaceae in a sclerophyllous oak community from Yunnan, Southwest China, is described and illustrated. Morphologically, it resembles both O. forrestii and O. georgei, while it is distinct in combined characters of wrinkled leaves, peduncle and pedicel covered with whitish and egladular villous hairs, bract lanceolate and nearly glabrescent adaxially, and staminode absent. Molecular phylogenetic analysis based on nuclear ribosomal internal transcribed spacer (nrITS) and chloroplast DNA fragment (trnL-F) of 61 congeneric species also supported O. oriolus as a new species while it was nested with O. delavayi. It was currently assessed as 'Critically Endangered' (CR) regarding to its small-sized population and narrow distribution following the IUCN categories and criteria.
