Erigeron evermannii is superficially similar to E. leiomerus and is sometimes misidentified as such; the latter has wider, more numerous, and merely glandular phyllaries, reflexing rays, non-folding leaves, and leafier stems. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The erect, involute ray laminae of Erigeron purpuratus, E. denalii, and E. pallens distinguish them from other species of sect. Tridactylia. Distinctions among these species were studied by G. L. Nesom and D. F. Murray (2004). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
