Petrocosmea glabristoma Z. J. Qiu & Y. Z. Wang, a new species from Yunnan Province, China, is described and illustrated. The new species is similar to Petrocosmea forrestii Craib and P. mairei Lévl., but differs from them mainly by its leaves triangular or triangular-ovate, corolla glabrous inside with shorter filament. Molecular and morphological data demonstrate that this new species has a close affinity to P. forrestii,
