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 aureus var. acutifolius has leaves apically acute (versus rounded to broadly obtuse, sometimes emarginate, in the typical form) and is known only from the type locality, a peat bog in British Columbia (Peace River District). It was not listed or otherwise recognized in a recent flora of that province (G. W. Douglas et al. 1998–2002, vol. 1). Erigeron ×arthurii B. Boivin was described as “sp. nov.” and was noted to have originated as a hybrid between E. acris and E. aureus. It was treated by E. H. Moss and J. G. Packer (1983) as a hybrid. Specimens cited by Boivin are from widely separated localities in southwestern British Columbia and adjacent Alberta. It was included at specific rank in the treatment by A. C. Budd et al. (1987) but not by H. J. Scoggan (1978–1979, part 4) or G. W. Douglas et al. (1998–2002, vol. 1). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
