Petrocosmea qiruniae M.Q.Han, Li Bing Zhang & Yan Liu (Gesneriaceae), a new species from Guizhou,China, is described and illustrated. It is most similar to P. leiandra (W.T.Wang) Z.J.Qiu in leaf blade shape and corolla type, especially in the colour of corolla throat and spots, indumentum of the stamens and the anther and ovary morphology. It was found on humid cliffs in an enormous limestone cave called the Qingxu Cave. In addition, Petrocosmea leiandra, based on P. martini H.Lév. var. leiandra W.T.Wang, originally published with very few descriptive data, is supplemented with more morphological data and a revised description.
