| Perennials, 5–55(–70) cm; rhizomatous, fibrous-rooted, caudices usually simple, thick. |
Perennials, 4–23(–33) cm; tap-rooted, caudices simple or branched. |
erect to basally ascending, hirsute to hirsuto- or strigoso-villous (hairs loosely appressed, slightly crinkled), sometimes loosely strigose distally (var. thompsonii), eglandular. |
erect to ascending or decumbent, strigose, rarely hirtellous, sometimes minutely glandular. |
basal (persistent) and cauline; basal blades linear-oblanceolate to broadly lanceolate or spatulate, (30–)50–100 × 5–25 mm; cauline gradually reduced distally (bases distinctly subclasping, except when greatly reduced), margins entire, faces hirsute, hirsuto-villous, sparsely villosulous, glabrate, or glabrous, eglandular. |
basal (persistent) and cauline; basal blades (3-nerved) linear to oblanceolate, 50–110(–190) × (1–)2–8(–13) mm; cauline gradually reduced distally, margins entire, faces loosely strigose to sparsely hirsuto-villous, eglandular. |
5–9(–12) × 10–22(–25) mm. |

2.5–5 mm (–6.8 mm in var. nevadincola). |
in 2–3(–4) series (margins usually ciliate), abaxially sparsely to moderately villoso-hirsute, usually eglandular, sometimes sparsely gland-dotted apically, rarely sparsely so over adaxial faces (especially in var. thompsonii). |
in 2–3(–4) series, hirsutulous to villous, sometimes minutely glandular. |

Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
