Erigeron gracilis “differs from E. ursinus in the strigose and scarcely glandular pubescence of the involucre, narrower and less herbaceous phyllaries, narrower and on the average longer disc-corollas, simple or nearly simple pappus, narrower ligules, on the average, and ordinarily narrower and slightly hairier leaves. E. gracilis grows at lower elevations than E. ursinus, in a drier habitat, and has a much more restricted range” (A. Cronquist 1947, p. 162). The two species are sympatric in northwestern Wyoming.
