Doellingeria is one of the genera of North American asters that sometimes has been treated as separate from Aster in a broad sense. J. C. Semple et al. (1991) recognized four species in their study of Aster sect. Triplopappus; G. L. Nesom (1993c) is followed here in excluding Oclemena reticulata. Semple et al. (2002) are followed here by excluding all eastern Asian species from the genus. Semple and J. L. A. Hood (2005) noted that the pappus of Doellingeria includes four distinct whorls of bristles, not three as had been thought since the first Flora of North America.
