  abstract  = {This paper deals with the taxonomical position and the nomenclature of two taxa belonging to the genus Sedum (Crassulaceae), today treated as Phedimus, namely Sedum middendorffianum Maxim var. diffusum Praeger and Sedum oppositifolium Sims. The correct taxonomical application of names is based on the nomenclatural types designated here.},
