Eriogonum diclinum is found infrequently in the Siskiyou and Trinity mountains of northwest California (Siskiyou and Trinity counties) and southwest Oregon (Jackson and Josephine counties). The species approaches E. incanum in aspect, and reports of that species in Oregon were based on staminate specimens of E. diclinum.

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.
