As a result of the studies, some changes were made to the taxonomy of the genus Medicago L. of modern Flora of Azerbaijan and the species of the genus are classified not in 4, but in 7 sections. The types grouped in each section were characterized by general constant morphological features. It was established that 17 spe- cies of the genus Medicago L were spread in Azerbai- jan. The information on the systematization, bioecological features of the sort and results of research of micromorphological features of seeds of views with disputable systematic classification was provided in the study For the first time under an electronic microscope (SEM) the micromorphology of seeds of 9 types of the sort Medicago L has been studied studied (M. littoralis,M. rigidula, M. truncatula, M. arabica, M. minima, M. polymorpha, M. meyeri, M. orbicularis, M. lupulina), be- longing to 3 sections (Spirocarpos, Orbiculares, Lupularia). The status of some types of the sort Medicago L. Trigonellinae of the triba of Trifolieae relat- ing to the subtriba was disputable, however, various form of seeds, the size and various color allowed to give independent status to these types. The studies demon- strated that the species of the genus Medicago L. varied not only in their macromorphological features, but also in micromorphological features. The seeds of the most of studied species of the genus Medicago L., along with different form, had different structure of epidermal layer. Some taxons (M. littoralis, M. truncatula, M. minima, M. meyeri) were a little different on morphological features, easily differed with features of microstructure of epider- mal layer. The study provided the results of indexation and cluster analysis according to the indicators of the micromorphological characteristics of each seed taxon in terms of shape, color, and surface structure, size. Taxonomical composition of taxons of the genus was presented on the basis of confirmed priority names of the International Botanical Nomenclature. The area of distribution of types of a sort in Azerbaijan was speci- fied.
