| Summary: | Some features of the distribution of aquatic vascular plants in Asian Russia (limits of distribution and phytogeographical patterns) are discussed. Many northern species penetrate far to the south via watersheds and mountain systems, while southern species go far to the north by the valleys of large rivers. Some species considered circumpolar are represented by 2–3 allopatric species. For some species, the ranges have been expanded in Asian Russia, some other taxa have been combined in one widespread species. The possible centers of the diversity of this group are outlined (Southern Siberia, Amur and Primorie areas, Central Yakutia and Kamchatka). Keywords: aquatic vascular plants, distribution, limits, patterns, Asian Russia
