Ceropegia gengmaensis P.R.Luo, A.Liu & H.Sun, a new species from Gengma County, Yunnan, Southwest China, is described. Both morphological characteristics and chloroplast phylogenetic analysis strongly support its placement within C. sect. Chionopegia H.Huber. Molecular data further reveal that C. gengmaensis is closely related to C. salicifolia, C. mairei, and C. dolichophylla, yet it can be distinguished from them readily by its stem indumentum, leaf shape, and floral morphology, particularly the shape of the corolla tube, and features of the lobes. A detailed line drawing of this new species is also provided.
