Erigeron flettii

Flett's fleabane, Olympic Mountain fleabane, Olympic Mountains fleabane, Olympic Mt. Fleabane

Habit Perennials 7–35 cm; taprooted, caudex branches relatively short and thick. Perennials 5–15 cm; rhizomatous, fibrous-rooted, caudex or rhizome branches relatively short and thick.
Stems

erect (often silvery white), densely strigoso-villous, eglandular.

basally ascending, sparsely villous to pilose, minutely glandular.

blades linear to linear-oblanceolate, 30–60 × 1–4 mm, cauline abruptly reduced distally, margins entire, faces silvery-strigose, eglandular.

mostly basal (persistent; petioles equaling or longer than blades);

blades spatulate to oblanceolate-spatulate, 10–50 × 4–12 mm, cauline abruptly reduced distally, margins entire (apices rounded), faces sparsely hirsute or glabrous, eglandular.

Involucres

5–7 × 10–15 mm.

6–8 × 10–15 mm.

Ray florets

30–55;

corollas white or pink, 6–13 mm, laminae reflexing.

corollas white, 7–10 mm (mostly 1–2 mm wide), laminae coiling tardily.

Disc corollas

3.5–5 mm.

3.5–4.5 mm.

Phyllaries

in 3–4 series, glabrous or sparsely strigose proximally, minutely glandular.

in 2–3(–4) series (purplish throughout or at margins and tips), hirsute to hirsuto-villous (hair cross walls clear or reddish to reddish purple), minutely glandular.

Heads

1–5(–10).

Discussion

Of conservation concern.

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

Erigeron flettii differs from E. grandiflorus in having fewer, wider, consistently white rays, broadly spatulate basal leaves with bases constricted into narrow petioles longer than the blades and apices rounded or obtuse, less dense involucral vestiture, and strongly barbellate pappus bristles. It is known only from the Olympic Mountains.
