|discussion=<p><i>Poa paucispicula</i> grows in arctic and alpine regions, from the north coast of Alaska and the western Northwest Territories south to Washington, Idaho, and Wyoming; it also grows in arctic far east Russia. It is a delicate species that prefers open, mesic, rocky slopes. It has sometimes been included in <i>P. leptocoma</i> (p. 573), a member of <i>Poa </i>sect.<i> Oreinos</i>. It differs from <i>P. leptocoma</i> in having smoother branches, fewer spikelets, and broader glumes. Chloroplast DNA studies confirm that it is not closely related to species of sect. Oreinos; ITS data support its relationship to <i>P. leptocoma</i>.</p>
