--><p><i>Eriogonum clavellatum</i> is relatively rare, known only from a few sites in the Four Corners area of San Juan County, Utah, Montezuma County, Colorado, and San Juan County, New Mexico. It has yet to be found in Arizona. The Comb Wash wild buckwheat is considered a “sensitive” species by the Bureau of Land Management throughout its range.</p>
