A new, yellow-flowered Sedum species is described from Turkey, S. euxinum. It is reported from three localities in the northeastern part of Anatolia. S. euxinum is classified in Sedum series Alpestria Berger. Its chromosome number is 2n = 48, but the species is considered to be diploid ( x = 24). S. euxinum is regarded as a neo-endemic because of its high secondary basic number and restricted distribution at the periphery of the area of S. series Alpestria.
