-->{{Treatment/Body
|discussion=<p><i>Festuca rubra </i>subsp.<i> aucta</i> is a coastal taxon, growing above the high tide line in the sand of stabilized sand dunes, beaches, etc., or in silt deposits. Its range extends along the Pacific coast from the Kamchatka Peninsula through the Aleutian Islands, Queen Charlotte Islands, and Vancouver Island and the adjacent continental coastline. <i>Festuca pseudovivipara</i> (p. 41S) has been described as a form of <i>F. rubra </i>subsp.<i> aucta</i>, but differs from that taxon in having pseudcviviparous spikelets. It is also ecologically, altitudinally, and probably reproductively isolated from <i>F. rubra </i>subsp.<i> aucta</i>.</p>
