-->{{Treatment/Body
|discussion=<p><i>Deschampsia sukatschewii</i> is a circumboreal species that extends from northern Russia through Alaska, northern Canada, and Greenland to Svalbard, and southward in the Rocky Mountains to <i>Nevada</i> and Utah. It ranges from short plants that form dense, mossy tufts on the Arctic coast to larger plants in subalpine and alpine habitats of the Rocky Mountains that have frequently been included in <i>D. cespitosa</i>.</p><!--
--><p>Arctic taxonomists recognize two subspecies of <i>Deschampsia sukatschewii</i> in arctic North America: the amphiberingian subsp. orientalis (Hulten) Tzvelev that extends to the northern coast of Alaska and the western Northwest Territories; and <i></i>subsp.<i> borealis</i> (Trautv.) Tzvelev, which is circumpolar in the arctic. Chiapella and Probatova (2003) treated these two subspecies, and subsp. sukatschewii, as subspecies of <i>D. cespitosa</i>. Efforts to circumscribe infraspecific taxa of <i>D. sukatschewii</i> for this treatment failed.</p>
