    Abstract

    Ceropegia polytricha, a new species from Yimen, Yunnan, China, is described and illustrated. The species is presently placed in Ceropegia sect. Chionopegia. Morphologically, it is similar to C. dolichophylla and C. sinoerecta in its tubular corolla with a trichome ring at the throat of the dilated part, narrowly triangular corolla lobes, and interstaminal lobes that form a shallow basal cup and are divided into pairs of narrowly triangular teeth at the apex, but clearly differs in its densely pilose stems and leaf blades, and longer corolla lobes. A comparison table of related species is provided.
