Annales Botanici Fennici56: 259-265






Oreocharis ovatilobata Q. Fu & Y.Q. Wang (Gesneriaceae) a new species from Guizhou Province in southwest China, is described and illustrated. It is morphologically similar to O. pankaiyuae and O. mairei, but differs from these congeners in particular by possessing ovate corolla lobes with purplish red spots at the obtuse apex, glandular-pubescent bracts and pistil, and by its adaxially white-pubescent leaf blade. Morphology (SEM) of leaf epidermis and seed coat of O. ovatilobata is also different from that of O. pankaiyuae.
