Oreocharis duyunensis Z.Y. Li, X.G. Xiang et Z.Y. Guo (Gesneriaceae), endemic to Guizhou, China, is described as a new species. The new species is easily distinguished from other Oreocharis species by having a white, stellate ring-like disc. Morphologically, the species is more similar to Oreocharis chienii (Chun) Mich. Möller & A. Weber, but differs from the latter with its densely white pilose leaves, mixed brown-pilose, pubescent and glandular-pubescent peduncle and pedicle, white stellate ring-like disc, and linear-lanceolate capsule. Based on the phylogenetic results and interspecific genetic distances of nuclear ITS and chloroplast trnL-F regions, O. duyunensis is a new species of uncertain phylogenetic position.
