|discussion=<p><i>Agrostis idahoensis</i> grows in western North America, from British Columbia to California and New Mexico, in alpine and subalpine meadows along wet seepage areas and bogs, and in wet openings with <i>Sphagnum</i> in coniferous forests. It was recently discovered in Chile and Argentina; it is not known whether it is native or introduced there (Rugolo de Agrasar and Molina 1997). <i>Agrostis idahoensis</i> is often confused with <i>A. mertensii</i> (p. 644) and dwarf forms of <i>A. scabra</i> (p. 646), both of which tend to grow in better-drained habitats.</p>
