Abstract
The significance of the systematic position for the traits of the leaf, mesophyll, chloroplasts, and pigment complex in steppe plants of the three main families Asteraceae, Poaceae, and Rosaceae from different geographical regions of Russia and Mongolia was examined. The species belonging to a particular family affects, first of all, the parameters of the whole leaf - the thickness and density of the leaf, as well as the size and number of mesophyll cells. In contrast, mesophyll parameters as well as pigment content independent of the taxon and both reflected the convergent response of plants from different taxa to climate.
