The article presents the results of the study of the ecology of Gentiana oschtenica by population-ontogenetic methods. Most coenopopulations have normal ontogenetic right-sided spectra with a maximum on the group of virginile or generative individuals. The state of coenopopulations is pessimal. The level of the ecological and geographical variability is significantly lower than the level of the intrapopulation variability. The data on the variability of morpho-parameters support the species independence of G. oschtenica.

The paper presents the results of a study of the distribution of species of the genus Galanthus on the territory of Adygea and the variability of individual morphological characteristics of individuals in natural populations. The study of intrapopulation variation of a number of parameters made it possible to identify stable and variable characteristics of species and to assess the polymorphism of populations.
