--><p><i>Doellingeria</i> is one of the genera of North American asters that sometimes has been treated as separate from <i>Aster</i> in a broad sense. J. C. Semple et al. (1991) recognized four species in their study of <i>Aster</i> sect. Triplopappus; G. L. Nesom (1993c) is followed here in excluding <i>Oclemena reticulata</i>. 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 <i>Doellingeria</i> includes four distinct whorls of bristles, not three as had been thought since the first Flora of North America.</p>
