Abstract. The paper presents the comparative analysis of the stem structure and leaf epidermis of 4 species of Pyrola L. genus growing in Blagoveshchensk area of the Amur region. For the first time the author determines the most important diagnostic and conditional-informative features, which can be used for intraspecific diagnostics. It was found that the stems of the species of Pyrola genus can be diagnosed by the thickness and topography of primary cortex tissue, the presence of secretions receptacles therein, the presence or absence of endoderm. Reliable informative features for diagnostics at interspecific level weren’t identified in the structure of leaf epidermis.
