|discussion=<p><i>Eriogonum pauciflorum</i> is the common, matted wild buckwheat on the Great Plains. The species occurs in southern Manitoba and Saskatchewan, northeastern Colorado, Montana, western Nebraska, North Dakota, Nebraska, South Dakota, and Wyoming. Plants from southeastern Wyoming, northeastern Colorado and western Nebraska have somewhat broader leaf blades (spatulate to elliptic rather than linear-oblanceolate to oblanceolate) that are densely tomentose to lanate on both surfaces (rather than loosely tomentose abaxially and less so or glabrous adaxially). Such plants have been distinguished as var. gnaphalodes. This expression would be worthy of a place in the rock garden. A hybrid between <i></i>var.<i> pauciflorum</i> and <i>E. effusum</i> has been named E. ×nebraskense Rydberg (see 2. <i>E. effusum</i>). The hybrid is known from Weld County, Colorado, Cheyenne, Dawes, Kimball, and Sioux counties, Nebraska, and Converse and Platte counties, Wyoming.</p>
