Varieties 6 (6 in the flora). J. L. Strother and W. J. Ferlatte (1988) provided a detailed study of Erigeron eatonii and its closest relatives (the following key is adapted from their study). Erigeron eatonii is regarded here as comprising a group of varieties with relatively discrete, nearly non-overlapping distributions, intergrading where their ranges are contiguous (for maps, see Strother and Ferlatte). Varieties villosus and lavandulus are exceptions: var. villosus occurs north of all other varieties except var. lavandulus, which occurs completely within the range of var. villosus and might justifiably be treated at specific rank. Variety nevadincola often has been treated at specific rank; its distinctions are quantitative (larger heads, florets, and fruits) and it intergrades with var. sonnei. Erigeron canaani occurs at the southwestern extreme of the range of E. eatonii var. eatonii and may be better treated at varietal rank within E. eatonii; as noted by Strother and Ferlatte, linear-leaves (diagnostic feature of E. canaani) occur in plants of var. eatonii in other parts of its range.
