Oreocharis qianyuensis, a new species of Gesneriaceae from Southwest, China based on morphological and molecular evidence

Oreocharis qianyuensis, a new species of Gesneriaceae from Southwest, China, is described and illustrated based on morphological comparisons and molecular phylogenetic analyses. Phylotranscriptomic analyses of the new species in the context of a comprehensive phylogeny with dense sampling of 88% (111/126) of all species of the genus indicated that the new species was most closely-related to O. fargesii. The new species is morphologically similar to O. fargesii and O. nanchuanica in the shape, color and structure of flowers and the number of stamens, but differs in the leaf blade shape, margin and the indumentum char-acters of the inflorescence. Its morphological relationship with similar species is discussed, the detailed descriptions, colour photographs, distribution, as well as the IUCN threatened status based on the IUCN Red List Categories and Criteria are also provided.
