Abstract. The paper presents a comparative analysis of the structure of the stem and leaf of two closely related species of the section Spiraea L. of the genus Spiraea L. growing in the Amur region. For the first time the article identifies the most important diagnostic and conditional-informative features, which can be used for interspecific diagnostics. It is stated that the stems of the species of the Spiraea section can be diagnosed only according to the structure of the core and a number of quantitative features. Leaves of the species under study are diagnosed on the basis of thickness of the lamina near the midrib and in the areas distant from ribs, thickness of the paxillate mesophyll, presence or absence of trichomes.
