|discussion=<p><i>Puccinellia vahliana</i> is an arctic species that is circumpolar, except in the Beringian region. In the Flora region, it extends from Alaska through northern Canada to Greenland. It is generally non-halophytic, growing in calcareous gravel, sand, clay, or moss of imperfectly drained moist areas, and on seepage slopes from near sea level to 700 m, or, rarely, in seasonally dry, turfy sites. It is often a pioneering species in moist clay and silt by alpine brooks, ephemeral lakes, glacial runoff streams, and on snowbeds. The roots of this species and <i>P. wrightii</i> are characteristically thicker and more tightly curled than those of other <i>Puccinellia</i> species. It sometimes hybridizes with <i>Phippsia algida</i>.</p>
