|discussion=<p><i>Eriogonum fusiforme</i> is widespread and common in southwestern Wyoming (Sweetwater County), eastern Utah (Carbon, Duchesne, Emery, Garfield, Grand, Kane, San Juan, Uintah, and Wayne counties), and adjacent western Colorado (Delta, Garfield, Mesa, Montrose, and Rio Blanco counties). In a “good” year, millions of individuals carpet the heavy clay flats and slopes (typically Mancos Shale), especially in Utah and Colorado. The plants can be so abundant and closely arranged that it can be difficult to walk through the tangle of stems and branches. This species is absolutely distinct from <i>E. inflatum</i> and no intermediates have ever been observed.</p>
