-->{{Treatment/Body
|discussion=<p><i>Poa arctica </i>subsp.<i> grayana</i> grows only in the alpine regions of the middle and southern Rocky Mountains of Utah, Wyoming, Colorado, and New Mexico. It is characterized by its glabrous calluses, densely hairy lemmas, and paleas that are densely hairy between the keels. It has less wiry culms, and panicles with more flexuous branches, than <i></i>subsp.<i> aperta</i> and, like that subspecies, can be difficult to distinguish from <i>P. arida</i> (p. 599).</p>
