|discussion=<p><i>Eriogonum shockleyi</i> is widely distributed in northern Arizona, east-central California, western Colorado, southern Idaho, northwestern New Mexico, <i>Nevada</i>, and Utah. On the Colorado Plateau, it has oblanceolate to spatulate leaf blades usually 0.3–1.2 × 0.3–0.6 cm, scapes 1–3 cm, involucres with long (2–3.5 mm) often spreading teeth, and flowers 3–4 mm. These plants have been distinguished as var. longilobum. The typical Great Basin expression has elliptic leaf blades 0.3–0.6 × 0.3–0.5 cm, scapes 0.5–2 cm, involucres with short (0.5–2 mm) erect teeth, and flowers 2.5–4 mm. Low, compact, hummock-like plants in southwestern Idaho with elliptic leaf blades 0.1–0.3(–0.35) × 0.1–0.15 cm, flowering stems absent or up to 0.5 cm, and involucres 2.5–3 mm with teeth 0.8–1 mm have been termed var. packardiae. These morphologic differences have been shown to be genetically insignificant, however (J. F. Smith and T. A. Bateman 2002). Plants on moving sand dunes at the southeast end of Baking Power Flat in Lincoln County, <i>Nevada</i>, can be up to 2 m across. Further studies may indicate that the various geographic expressions deserve taxonomic recognition.</p><!--
--><p>The Great Basin expression is the food plant of the Bernardino dotted-blue butterfly (Euphilotes bernardino). Members of the species are occasionally found in cultivation.</p>
