|discussion=<p><i>Anthoxanthum occidentale</i> grows in moist to fairly dry forested areas, from Klickitat County, Washington, south to the coastal mountains of San Luis Obispo County, California. Its long flag leaf blades and more elongate spikelet parts make it easier to distinguish from <i>A. hirtum</i> than the key suggests.</p>
