| Perennials 5–15 cm; rhizomatous, fibrous-rooted, caudex or rhizome branches relatively short and thick. |
Perennials, 7–25 cm; taprooted, caudices woody, branches usually vertical or horizontal (2–10 cm), sheathed by persistent leaf bases. |
basally ascending, sparsely villous to pilose, minutely glandular. |
erect, sparsely to moderately hispidulous to hirsute, minutely glandular to stipitate-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.) |
