|discussion=<p><i>Eremopyrum</i> includes 5-10 species that grow in steppes and semidesert regions from Turkey to central Asia and Pakistan. Three species have been found in North America; only <i>E. triticeum</i> is widepsread. In their native ranges, species of <i>Eremopyrum</i> are valuable fodder on ephemeral spring pastures.</p>
