Erigeron flettii

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

Habit Perennials, 5–55(–70) cm; rhizomatous, fibrous-rooted, caudices usually simple, thick. Perennials 5–15 cm; rhizomatous, fibrous-rooted, caudex or rhizome branches relatively short and thick.
Stems

erect to basally ascending, hirsute to hirsuto- or strigoso-villous (hairs loosely appressed, slightly crinkled), sometimes loosely strigose distally (var. thompsonii), eglandular.

basally ascending, sparsely villous to pilose, minutely glandular.

Leaves

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.

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

5–9(–12) × 10–22(–25) mm.

6–8 × 10–15 mm.

Ray florets

30–80;

corollas usually blue to rose purple or pink, sometimes white to pale blue, 12–20(–25) mm (mostly 1.5–3 mm wide), laminae coiling.

25–40;

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

Disc corollas

3.5–4.5 mm.

3.5–4.5 mm.

Phyllaries

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

Heads

Cypselae

2.5–2.8 mm, (4–)5(–7)-nerved, faces sparsely strigose;

pappi: outer of setae, inner of 20–32 bristles.

2–2.8 mm, 2-nerved, faces strigose;

pappi: outer of setae, inner of 15–20 bristles.

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.
