A study of the Teucrium L. genus in the Azerbaijan flora based on herbarium materials

In 1957 Ya. M. Isayev described 8 species of the Teucrium L. genus in the flora of Azerbaijan. About 620 herbarium specimens of the genus were analyzed in the Herbarium Fund of the BAC. During the revision of the herbarium specimens, the place and time of collection of the species of the genus, as well as the persons who collected and identified them, were studied. According to the results obtained as a result of the analysis of the herbarium fund, literary data and Internet databases, changes in the nomenclature within the genus require modern studies of the taxonomy of species common in Azerbaijan.
