Eriogonum collinum is infrequent to locally common in the Lahontan Basin region of the Intermountain West in northeastern California (Lassen and Modoc counties), south-central Oregon (Lake County), and northwestern Nevada (Douglas, Humboldt, Lyon, Pershing, Storey, and Washoe counties).

Eriogonum gossypinum is rare to infrequent on the foothills of the Inner Coast Ranges in Kings (Kettleman Hills) and eastern San Luis Obispo counties, with two centers of concentration in Kern County, one in the Taft area and another east of Bakersfield. The Kern County populations are the most extensive and subject to the greatest habitat destruction. The species is protected at The Nature Conservancy’s Sand Ridge Preserve near Edison.
