|discussion=<p><i>Eriogonum maculatum</i> is the most common and widespread expression of the <i>E. angulosum</i> complex, being found in Arizona, California, southwestern Idaho, <i>Nevada</i>, northwestern New Mexico, eastern Oregon, western Utah, and southeastern Washington. It is often common to abundant and may even be weedy, especially along roadsides intermixed with other annual wild buckwheats. The swollen bases of the outer tepals readily distinguish the species. The greatest concentrations of the spotted wild buckwheat are found in the Mojave Desert and the Great Basin. A specimen supposedly found on the “Laramie Plains” of Wyoming (Parry s.n., 1882, ISC) is discounted as to location.</p>
