|discussion=<p><i>Danthonia unispicata</i> is restricted to western North America, where it grows in prairies and meadows, on rocky slopes, and in dry openings up to timberline in the mountains. It differs from <i>D. californica</i> in its shorter stature, usually densely pilose foliage, short, erect pedicels, and the usually erect cauline leaf blades. It is closely related to <i>D. californica</i>, and some authors prefer to treat it as <i>D. californica</i> var. unispicata Thurb.</p>
