--><p>G. L. Nesom (1994b) included Herrickia within Eurybia, as sect. Herrickia in subg. Eurybia, adding E. glauca and E. wasatchensis to the section. L. Brouillet et al. (2004) added H. kingii to the group and confirmed the membership proposed by Nesom using molecular phylogenetic data. Previously, Nesom (1991e) had placed H. kingii in Tonestus, a polyphyletic group. In the eurybioids, a grade basal to subtribe Machaerantherinae, the order of appearance of the genera recognized here is: Oreostemma, Herrickia, Eurybia, and Triniteurybia. This underscores the intermediate position of the eurybioids between basal x = 9, asterlike, more or less mesic ancestors, and the more xeric and derived Machaerantherinae.</p>
