Family Crassulaceae St.-Hil. in the Crimea.
In the article the critical review of family Crassulaceae for Crimea (Russia) including information on 19 wild and naturalized species and on 19 hardy cultivated species is given. Two new combinations Crassulaceae subtrib. Sempervivinae (A. Berger) Byalt, comb. et stat. nov. Sedum subgen. Petrosedum (Grulich) Byalt, comb. et stat. nov. are supported. Herbarium specimen of J. Amman preserved in Herbarium of Komarov Botanical Institute RAS (LE) is selected as lectotypus for Sedum hybridum L. (= Aizopsis hybrida (L.) Grulich). Lectotypes for the names Crassula caespitosa Cav. (= Sedum caespitosum (Cav.) DC.) and Sedum sexfidum Fisch. also are proposed. We present Conspectus and keys for identifying of genera and species of wild-growing Crassulaceae, as well as a separate conspectus and keys for the main outdoor cultivated Crassulaceae species. In the Conspectus of wild species, the H. 't Hart system (1995) is used with some modifications. For wild and wild species of Crassulaceous, maps of their distribution on the peninsula are given. The article is illustrated by 10 photos.
