Abstract
The attempt of local floras (LF) types division in Middle Siberia North by their latitudinal element proportions with application of cluster analysis is initiated. For this purpose the lists of 82 LF are used, as by author’s generated, as well as by taken from literature sources. Cluster borders, marked on the map in tundra zone, corresponds with generally accepted zone borders. Accordingly with range of latitudinal fractions, the next types of LF are divided: high arctic, arctic, hypoarctic and boreal.
