Varieties 2 (2 in the flora). Erigeron aphanactis is distinguished from E. austiniae by its conspicuously puberulent (versus essentially glabrous) disc corollas and white (versus yellow) carpopodia; it also is similiar in habit and vestiture to E. concinnus, which has conspicuous white to pinkish rays.

Erigeron salmonensis is known only in the Salmon River Canyon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
1. Stems leafy; heads usually 2–3; disc corolla lobes usually yellowish | var. aphanactis |
1. Stems scapiform; heads 1; disc corolla lobes sometimes becoming reddish or purplish | var. congestus |
