Brewer's daisy, Brewer's fleabane
|
purple fleabane
|
| 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, (2–)3–9(–14) cm; taprooted, caudices diffuse with extensive systems of rhizomelike, relatively long and slender branches. |
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. |
erect (simple, ± scapiform), villous, 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. |
mostly basal (persistent); blades linear to narrowly oblanceolate, 15–30(–45) × 1–2.5(–3) mm, margins entire or (mostly on early leaves) with 1–2 shallow lateral lobes or teeth, faces sparsely hirsuto-villous or glabrous, minutely glandular. |
mostly 4–6 × 9–14 mm. |
6–9(–10) × 9–15 mm. |
20–62; corollas white or pink, often drying blue, 4–7 mm, laminae weakly coiling. |
40–90; corollas white to pink or purplish, 5–9 mm, laminae (filiform, 0.3–0.8 mm wide, involute) erect, not coiling or reflexing. |
3.5–5.5 mm (throats slightly indurate, not inflated). |
4–5 mm. |
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 2–3 series, sparsely pilose (hairs 1–3 mm, with colored cross walls) or glabrous, minutely glandular. |
1 or 2–5(–10) in loosely corymbiform arrays. |
1. |
2–3 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (15–)20–35(–50) bristles. |
1.8–2.7 mm, 2-nerved, faces sparsely strigillose to glabrate; pappi: outer 0 (or inconspicous), inner of 28–40 (pinkish to purplish) 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.) |
The erect, involute ray laminae of Erigeron purpuratus, E. denalii, and E. pallens distinguish them from other species of sect. Tridactylia. Distinctions among these species were studied by G. L. Nesom and D. F. Murray (2004). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
