| Perennials, 7–75 cm; taprooted (taproots usually not collected, often weakly developed), roots and caudices woody, branches rhizomelike (3–15 cm; fibrous-rooted), relatively slender, leafless, ascending. |
Perennials, 15–28 cm; taprooted (root or caudex branches 1–4 cm, rhizomelike or caudexlike). |
usually ascending, sometimes prostrate to procumbent or decumbent (var. jacinteus) (often purple, distal branches stiff, spreading-ascending), hispid (hairs spreading-deflexed, 0.1–0.4 mm), mostly eglandular. |
decumbent-ascending (distal branches spreading-ascending, axillary tufts of smaller leaves prominent at most nodes), sparsely to moderately strigose (hairs ascending-appressed), eglandular. |
cauline; (ascending) blades narrowly oblong-lanceolate to narrowly obovate, 10–40 × 2–5 mm, margins entire, relatively evenly spaced and sized, hispid, mostly eglandular. |
cauline; blades oblanceolate, (25–)30–45 × (2–)5–8 mm, reduced near heads, margins entire, faces sparsely to moderately strigose, eglandular. |
mostly 4–6 × 9–14 mm. |
mostly 4–5 × 8–12 mm. |
20–62; corollas white or pink, often drying blue, 4–7 mm, laminae weakly coiling. |
18–22; corollas bluish, 5–8 mm, laminae sometimes coiling slightly at tips. |
3.5–5.5 mm (throats slightly indurate, not inflated). |
4–4.5 mm (throats slightly indurate, not inflated). |
in 3–5 series (all but outermost with stramineous margins and distal, greenish-herbaceous, narrowly rhomboid areas), strigoso- to hispido-hirsute or essentially glabrous, densely minutely glandular. |
in 3–5 series, outer (midnerves prominently orange-resinous) sparsely strigose (hairs thin-based), eglandular (inner: margins broadly scarious, nearly winglike). |
1 or 2–5(–10) in loosely corymbiform arrays. |
1 or 2–4 (in loosely corymbiform arrays). |
2–3 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (15–)20–35(–50) bristles. |
2–2.4 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 28–32 bristles. |

Varieties 5 (5 in the flora). Erigeron breweri is treated as a member of E. sect. Linearifolii in G. L. Nesom (1992b), where all of the varieties are mapped in detail. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Erigeron mariposanus is closely similar to E. aequifolius. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
