Abstract. The paper presents the comparative analysis of the structure of the rhizomes and roots of two morphologically similar species of the genus Valeriana L. growing in Blagoveshchensk district of the Amur region. For the first time the article identifies the most important diagnostic and nominal-informative features, which can be used for intraspecific diagnostics. It is stated that for the rhizomes of the species under study the informative features are the thickness of primary bark, the presence or absence of endoderm and sclerenchyma ring around central cylinder, the structural features of core cells. The roots of the genus Valeriana are well diagnosed on the basis of primary bark thickness, the shape, location and size of xylem vessels, the presence or absence of sclerenchyma in the centre.
