Eriogonum salicornioides is known from Harney and Malheur counties in southeastern Oregon and Elmore and Owyhee counties of southwestern Idaho. Its attribution to Nevada is based on a Percy Train collection (Jun 1934, NY, PAC) from a dry desert valley in northern Humboldt County. Efforts to relocate the species in that state have been unsuccessful.
