Sedum xinchangense (Crassulaceae), a new species from Zhejiang, eastern China, is described with illustrations. The new species is morphologically similar to S. lungtsuanense and S. stellariifolium, but can be distinguished by a combination of morphological characters, including the presence of stolons, leaf and sepal shape, indumentum type, flower number, and leaf and seed size. Phylogenetic analyses also confirmed its distinct species status, placing it within the Acre clade of subfamily Sempervivoideae. Based on both morphological and molecular evidence, we assign the new species to sect. Sedum.
