|discussion=<p><i>Bromus richardsonii</i> grows in meadows and open woods in the upper montane and subalpine zones, at 2000-4000 m in the southern Rocky Mountains, and at lower elevations northwards. Its range extends from southern Alaska to southern California and northern Baja California, Mexico; it is found as far east as Saskatchewan, South Dakota, and western Texas. Specimens with pubescent nodes and glumes are apparently confined to the southwestern United States.</p>
