An overview of Russian literature sources of urban flora studies. The authors analyze the history of urban floral research in Russia and provide definitions of terms – urban flora, native, indigenous, apophytic, alien, synanthropic species. The overview provides a description of methods and approaches used in different studies of urban flora. Special attention is paid to the analysis of the biological diversity of native and alien plants and the features of their spatial distribution in urban habitats. The authors raise problems of protection of biodiversity in cities and show the role of urban protected natural areas. The conclusion of the work outlines the prospects for further study of urban flora. The authors highlight an importance and necessity of creation of a unified database of vascular plants in the urbanized territories of Russia. Further usage of the database will allow to conduct a comparative analysis of the species composition of urban flora and to identify the degree of their homogenization and originality.
