| Perennials, (3–)6–12 cm; taprooted, caudices usually branched. |
Perennials 5–15 cm; rhizomatous, fibrous-rooted, caudex or rhizome branches relatively short and thick. |
erect (distinctly white in proximal portions), usually strigose at least on distal 1/2, sometimes strigoso-hirsute or mixed-hispid, minutely glandular. |
basally ascending, sparsely villous to pilose, minutely glandular. |
mostly cauline (proximal internodes elongate; petioles prominently ciliate, hairs spreading, thick-based); blades linear to linear-oblanceolate, 20–40 × 1–1.5 mm (on proximal 1/2–2/3 of stems), (bases relatively thin, not sheathing) margins entire, hispido-ciliate, faces strigose. |
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. |
3.5–4 × 5–10 mm. |
6–8 × 10–15 mm. |
25–40; corollas yellow, drying dark yellow (sometimes fading on drying and appearing whitish or creamy), 4–9 mm, laminae coiling. |
25–40; corollas white, 7–10 mm (mostly 1–2 mm wide), laminae coiling tardily. |

in 2–3 series, hirsuto-villous, sometimes 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. |

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