It grows in forest, forest-steppe and steppe zones. The structure of leaves in wormwood plants growing in contrasting habitats is compared. The leaves differ greatly in their size, degree of the palisade and water-storing tissues development in the mesophyll, the thickness of the epidermal cells external walls, the density of stomata location and the density of pubescence, the relative conducting surface, etc. The characters for which difference between the studied samples was detected are treated in ecological anatomy as adaptively significant. Along with ecologically-geographical variability this species is characterized by significant endogenous variability, on the basis of which specialized forms can originate. It affects the number of generations of cells in the tissues of the plate, its thickness, the ratio between the conducting tissues in the petiole and the relative conductive surface. Refs 42. Figs 2.
