The paper gives the variation data related to some quantitative characters and anatomy of Phlox sibirica L. leaf blade. The most stable characteristics of Phlox sibirica leaf anatomy are the leaf thickness around the midrib, the length of upper mesophyll layer cells, the number of epidermal cells, and the stoma sizes, which, along with the peculiarities of mesophyll structure, conducting bundles and stomatal type, can serve as additional diagnostic characters for species identification. Phlox sibirica is classified as xerophyte-heliophyte morphological type.
