Abstract

Lectotypes are proposed for Linnaeus's names for European species belonging to Sedum subgen. Sedum, i.e. S. acre L., S. album L., S. annuum L., S. atratum L., S. caeruleum L., S. cepaea L., S. dasyphyllum L., S. hispanicum L., S. reflexum L., S. rubens L., S. rupestre L., S. stellatum L., S. villosum L., and for Tillaea rubra L., which is the basionym of S. rubrum (L.) Thell. For S. sexangulare L. a neotype is proposed which has been chosen from the material in the Linnaean herbarium in Stockholm. The typification of these names in all cases serves to maintain general usage. In particular, the typification of S. sexangulare, S. rubens, S. rupestre, and Tillaea rubra helps to settle disputes about the application of these names, guarantees their unambiguous use, and thus serves stability of nomenclature.
