Perennials 5–15 cm; rhizomatous, fibrous-rooted, caudex or rhizome branches relatively short and thick. |
Perennials, 3.5–8 cm; taprooted, caudices simple or branched, relatively long, woody. |

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.) |
Erigeron lackschewitzii is closely similar to E. ochroleucus and perhaps derived from it. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
