Abstract

Ceropegia sunhangii P.R. Luo & T. Deng, a new species from Qiaojia, Yunnan, China, is described and illustrated herein. This species is similar to C. christenseniana Hand.-Mazz.and C. sinoerecta M. G. Gilbert & P. T. Li but can be distinguished easily by its stem, indumentum, leaf size, and floral features, especially the corolla shape and size, the corolla tube and corolla lobe characters.
