|discussion=<p><i>Eriogonum tumulosum</i> is infrequent in Duchesne, Emery, eastern Sevier, and Uintah counties, Utah, and in western Moffat County, Colorado. It is often confused with <i>Parthenium ligulatum</i> (M. E. Jones) Barneby (<i>Asteraceae</i>); they grow together and both form dense hummock-like mats. Woodside wild buckwheat is seen infrequently in rock gardens.</p>
