A new species, Sedum guangxiense sp. nov., discovered in Guangxi Province, China, is described and illustrated. Molecular phylogenetic analyses and morphological differences indicate that this species is well separated from its close relatives in Sedum, justifying its recognition as a distinct new species. Morphologically, it closely resembles Sedum tosaense and S. emarginatum in its leaf shape, inflorescence type and life form, but it can be easily distinguished in its erect stems when young, much larger leaves, narrowly triangular petals, ovate nectar scales and oblong anthers.
