Erigeron nivalis usually has been treated as an infra-specific taxon within E. acris; the two are broadly sympatric in the northwestern United States and Canada without obvious intergrades. Both occur over a wide range of elevations and in similar habitats. Erigeron nivalis probably occurs in Nevada; it has not been taxonomically distinguished there. Erigeron scotteri was regarded by E. H. Moss and J. G. Packer (1983) as a synonym of E. acris (presumably var. debilis = E. nivalis; the heads are relatively small and borne singly).

Of conservation concern. Erigeron lemmonii is found only in the Scheelite Canyon, Huachuca Mountains (Cochise County), on Fort Huachuca Military Reservation. The basal portion of the stems may be “subnaked and rhizomatous in appearance, but apparently not subterranean” (A. Cronquist 1947).
