Circumarctic encircle the northernmost regions of the Northern Hemisphere. The local flora is poor in numbers of species; we can find on this wide area only about 1400 species of vascular plants, some of which are glacial relicts. There is only a single endemic genus. More plentiful are bryophytes and lichens.
