Abstract
We describe and illustrate Sedum lipingense (Crassulaceae), a new species of stonecrop found in the limestone areas of SE Guizhou, China. Based on the presence of adaxially gibbous carpels and follicles, this taxon belongs to sect. Sedum S.H. Fu. The new species superficially resembles S. subtile Miquel and S. bulbiferum Makino but differs from these two taxa in its development of a basal leaf rosette during florescence. The nrDNA internal transcribed spacer (ITS) sequences also support the claim that this plant is a new species in the Sedum genus.

Diagnosis: Sedum lipingense can be distinguished from the closely related S. subtile and S. bulbiferum by the presence of rosettes, absent sterile shoots and bulbils, subequal lanceolate-oblong sepals, and other traits.
