Oreocharis thanhii, a new species from Lai Chau Province, Northwest Vietnam, is described and illustrated. It is morphologically most similar to O. obliqua in purple flower, slender cylindrical corolla tube, and free anthers but differs from the latter by having fewer lateral veins, simple cyme or simple dichasium inflorescence, glandular-puberulent filaments and styles. Besides providing a detailed description and preliminary conservation status of this novelty, its key discriminative characteristics with related species are also presented in this paper.
