Varieties 3 (3 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 2 (2 in the flora). Eriogonum marifolium is dioecious, with the two sexes having such markedly different morphology that collectors often consider each to represent a different species. In Oregon, male plants of E. marifolium and E. umbellatum var. haussknechtii can be difficult to distinguish. In El Dorado and Placer counties, California, herbarium specimens of E. marifolium and E. incanum can be difficult to separate, as their distribution ranges overlap there.
