|discussion=<p><i>Glyceria leptostachya</i> grows in swamps and along the margins of streams and lakes, on the western side of the coastal mountains from southern Alaska to San Francisco Bay. It is similar to the European <i>Glyceria notata</i>, differing primarily in its tendency to have fewer spikelets [3-8(10) vs. 5-15(19)] on its branches.</p>
