|discussion=<p><i>Glyceria borealis</i> is a widespread native species that grows in the northern portion of the Flora region, extending southward through the western mountains into northern Mexico. It grows along the edges and muddy shores of freshwater streams, lakes, and ponds. In the southern portion of its range, <i>G. borealis</i> is restricted to subalpine and alpine areas. The midcauline leaves of <i>G. borealis</i> almost always have densely papillose upper leaf surfaces. Voss (1972) stated that such surfaces are non-wettable and develop on the floating leaves.</p><!--
--><p><i>Glyceria borealis</i> differs from <i>G. notata</i> in having acute lemmas and, usually, densely papillose midcauline leaves.</p>
