Towards a review of the genus Petrosedum (Crassulaceae): Taxonomic and nomenclatural notes on Iberian taxa

AbstractFollowing on from the results of the research carried out by Nikulin et al. the author moves some names of Sedum L. ser. Rupestria Berger (Crassulaceae) to Petrosedum Grulich, in order to complete the transfer begun by Grulich in 1984 and to prepare the review of the genus. Several recombinations had already been made, but some of these are illegitimate; moreover there is an almost complete lack concerning the Iberian Peninsula. In this paper new combinations, names at a new rank and some additional synonyms are proposed for Sedum amplexicaule var. ciliatum Lange,Sedum boryanum Bory ex DC., Sedum fruticulosum Brot., Sedum sediforme var. congestiflora Camara, Sedum s. var. dianium O. Bolos, Sedum s. var. saguntinum O. Bolos, Sedum tenuifolium subsp. ibericum ‘t Hart, Sempervivum anomalum Lag. and Sempervivum hispanicum Willd. Typifications are provided for Sedum amplexicaule var. ciliatum Lange, Sedum guadarramicum Sennen, Sempervivum anomalum Lag. and Sempervivum hispanicum Willd.
