Results of studies of the anatomical structure of leaf blade of Siberian feather grasses are presented. A cross sections of leave blades were studied in 15 species: S. capillata, S. grandis, S. krylovii, S. baicalensis, S. praecapillata, S. consanguinea, S. orientalis, S. lessingiana, S. kirghisorum, S. dasyphylla, S. pennata, S. pulcherrima, S. zalesskii, S. glareosa, S. klemenzii. The following diagnostic characters were identified: relative height and degree of expressiveness of edges, quantity and type of veins, extent of development and arrangement of sclerenchyma as well as number and type of trichomes on the adaxial surface of leaves. Despite the uniformity of these features in many species within sections, they exhibit distinctive morphological patterns and have been proved to be taxonomically useful.
