Comparative Characteristics of the Hygromorphic Composition of the Leading Families of Florae of Different Regions of Russia

Each family of higher vascular plants demonstrates a certain degree of ecological community. In this paper, the ecological characteristics of families were estimated by the ratio of groups of hygromorphs (ecological groups of species in relation to soil moisture conditions). Hygromorphs are part of the general sys- tem of plant ecomorphs, which was developed by A. L. Belgardas. The characteristics of the families of the flora of Samara region are compiled on the basis of data on 8 groups of hygromorphs.
