Notes



Known only from the high Sierra Nevada; field surveys needed. Occurrences from Kern Plateau are threatened by trampling and grazing. Previously Considered But Rejected as being a synonym of E. spergulinum, a common taxon; many collections of E. spergulinum from FRE Co. need to be examined to confirm their varietal identification. See Leaflets of Western Botany 3(9):201-202 (1943) for original description, and 6(4):75-80 (1950) for taxonomic treatment.
