Notes: Atriplex prostrata is native and common on the seashores of northern Europe. Pedersen (1972) reported it, under several names, as casual in southwestern Greenland. The species has not been accepted recently from Iceland (Gustafsson 2001; Kristinsson 2010) but was collected there in 2010, may have been overlooked, and may reach the Arctic. Whether it occurs as native in North America is debatable.
Two races are often recognized in northern Europe: subsp. prostrata and subsp. calotheca (Rafn) M. Gust. (= A. hastata L. nom. rejic.). The latter is a regional plant on the shores of the Baltic, in Denmark, and in southern Norway, by many authors (e.g., Gustafsson 2001) accepted as species but with no arctic or near arctic records. This means that the often applied name A. hastata is irrelevent for arctic plants.
