Lemmon's fleabane

Brewer's daisy, Brewer's fleabane
|
Perennials, 10–25(–60) cm; taprooted. |
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. |
decumbent-ascending to prostrate (greenish, sometimes producing erect branches), hirsute to hispido-pilose, minutely glandular. |
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. |
basal (not persistent) and cauline; (greenish) proximal blades oblanceolate to obovate, 5–12 × 1–3 mm, reduced distally, margins with 1–2 pairs of teeth or shallow lobes, distal entire, faces piloso-hirsute, densely minutely glandular. |
cauline; (ascending) blades narrowly oblong-lanceolate to narrowly obovate, 10–40 × 2–5 mm, margins entire, relatively evenly spaced and sized, hispid, mostly eglandular. |
2.5–4 × 5–10 mm. |
mostly 4–6 × 9–14 mm. |
42–60, corollas white, without abaxial midstripe, 3–7 mm, laminae not coiling or reflexing. |
20–62; corollas white or pink, often drying blue, 4–7 mm, laminae weakly coiling. |
1.8–2.4 mm. |
3.5–5.5 mm (throats slightly indurate, not inflated). |
in 2–3(–4) series (erect, apices appressed), sparsely piloso-hirsute, minutely glandular. |
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. |
1–3. |
1 or 2–5(–10) in loosely corymbiform arrays. |
1–1.2 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 7–10 bristles. |
2–3 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (15–)20–35(–50) bristles. |

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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
