|discussion=<p><i>Aristida purpurea </i>var.<i> longiseta</i> grows on sandy or rocky slopes and plains, and in barren soils of disturbed ground from western Canada to northern Mexico. It is the most variable variety of <i>Aristida purpurea</i>, ranging from short plants with basal leaves and short panicles suggestive of <i></i>var.<i> fendleriana</i>, to tall plants with long cauline leaves and long, drooping panicles resembling <i></i>var.<i> purpurea</i>. The length of its glumes, width of its lemma apex, and the length and thickness of its awns distinguish it from all the other varieties. The callus and long, stiff awns are especially troublesome to sheep and cattle.</p>
