Information on xerophytes vegetation and its classification is provided in the review from the point of view of ecology, physiology and morphology. The adaptive signs allowing ксерофитам to exist in the conditions of constant or seasonal deficiency of moisture are considered. The approaches developed by various researchers to classification ксе¬рофитов are discussed. It is noted that force of not specificity of adaptations division of plants into groups ксерофитов often causes difficulties, but it is possible to allocate the main directions of adaptations: in deserts of a moderate belt it is a xerophytization and an efemerization, in highlands – a kriofilization and a sklerifikation. Author’s classification ксерофитов florae of the Russian Caucasus which basis the principles are is offered: evolutionary, anatomo-morfologo-physiological, edafichesky. Aren’t included in classification пойкилоксерофиты as representatives of this group among the highest vascular plants in the studied territory are absent.
