Abstract

Petrocosmea melanophthalma Huan C. Wang, Z. R. He & Li Bing Zhang, an attractive new species (Gesneriaceae, Petrocosmea sect. Deianthera W. T. Wang) from Yunnan, China, is described and illustrated. It is similar to P. kerrii Craib in the zygomorphic calyx and brevirostrate anther. The new species differs from the latter by its peltate leaves and the blue corolla with two striking black spots on the tube, as well as the geniculate filaments of the stamens that thicken above the middle. Petrocosmea melanopthalma was found on basalt cliffs in evergreen broad-leaved forest on Mopan Shan.
