Here we present results of our study on the leaf blades epidermis using scanning electron microscopy for 16species of Festuca from Altai. The factor analysis of mixed data revealed markedly differentiated groups according to theirsectional devision. This result supports the previous phylogenetic findings in the genus, except the section Aulaxyper. Thestudy also demonstrates the importance of the abaxial side of leaves in taxonomic treatment of the species, specifically theshape of long cells and silicon bodies, as well as the location of the latter.
