The intra-and interpopulation variability of six populations of Tulipa uniflora (L.) Besser ex Baker at the northern limit of distribution in the Angara steppes over 12 morphometric parameters was studied by the principal components method and single-factor analysis of variance. It is established that the vectors characterizing the gradients of the change in the morphometric parameters are divided into two groups: vegetative and generative, which are among themselves in direct dependence. Based on the single-factor analysis of variance results for all morphometric parameters, a significant difference is observed between populations of T. uniflora in the Angara Region. On the one hand, this is a consequence of anthropogenic impact on the population, and on the other – the relic nature of the species.
