The structure of geographical (arealogical) elements is one of the most important flora characteristics, because genetic composite groups are established on the basics of generic and species areas analysis and regularities of flora formation are determined. The object of the research is a complete species composition of vascular plants, revealed within the boundaries of the researched forest-steppes - Krasnoyarsk, Kansk and Achinsk (Krasnoyarsk Region). The North forest-steppes flora was detected by the specific flora method established by A.I. Tolmachev. The aim of this work is to summarize materials of the Euro-Siberian geographical element flora structure in the North forest-steppes ecosystems of the Middle Siberia with the characteristics of geographical elements selected on the basis of the fitohorions concept. It is based on the accordance principle of species distribution to natural (Botanical-geographical) zoning of the Earth. To determine the areas we used modern planetary floristic zoning established by A.L. Takhtajan with some amendments: floristic zoning by L.I. Malysheva was taken into account to Siberia, etc., the Russian Far East - by R.V. Camelina. As a result of the work geographical elements of the boreal group were assigned: Circumboreal (133 species, 9,6% of the whole flora), Eurosiberian (384 species, 27,7%), Pontic-South Siberian (81 species, 5,85%), Siberian (154 species, 11,12%).
