Abstract
The author describes a new species of Crassulaceae, Phedimus yangshanicus, growing on limestone rocks or hills in Guangdong, China. Morphologically unique in the genus, this plant is distinguished from the other species by its dimorphic leaves. The plant shows obviously pseudopetiolated big basal leaves, which appear nearly opposite due to shortening of the nodes and are persistent at anthesis, and has alternate small leaves on the flowering stem.
