TO THE PETROPHILIC FLORA OF INLAND DAGESTAN
Petrophytes are a peculiar group of plants confined to stony, stony-gravelly substrates, the study of which is important for understanding the history of the flora of mountain areas. The taxonomic composition, ecological-biological and geographical-genetic features of the petrophilic flora are characterized by the fact that the rocky terrain of the study area, such as rocks, scree, pebbles, create favorable conditions for the development of this ecological group of plants. This article contains information about taxonomic, ecological-biomorphic, and ecological-biological analyses of petrophilic flora in the vicinity of the Arakani formation in the Untsukul district of Intra-Mountainous Dagestan. According to herbarium specimens Petrovichev identified taxonomic categories of the studied flora. Biomorphic and ecological-biological analyses of petrophilic flora were performed.
