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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum exilifolium is known only from Grand, Jackson, and Larimer counties, Colorado, and from Carbon and Albany counties, Wyoming. The drop-leaf wild buckwheat is a “species of concern” in Wyoming. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
