L. Nesom (1994b) included <i>Herrickia</i> within <i>Eurybia</i>, as sect. <i>Herrickia</i> in subg. <i>Eurybia</i>, adding <i>E. glauca</i> and E. wasatchensis to the section. L. Brouillet et al. (2004) added <i>H. kingii</i> to the group and confirmed the membership proposed by Nesom using molecular phylogenetic data. Previously, Nesom (1991e) had placed <i>H. kingii</i> in <i>Tonestus</i>, a polyphyletic group. In the eurybioids, a grade basal to subtribe Machaerantherinae, the order of appearance of the genera recognized here is: <i>Oreostemma</i>, <i>Herrickia</i>, <i>Eurybia</i>, and <i>Triniteurybia</i>. 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> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Leaves basal and cauline; plants taprooted or with caudices; rays white to pale lavender |[[Herrickia kingii|Herrickia kingii]] |-id=key-0-1 |1 |Leaves mostly cauline; plants rhizomatous; rays purple |[[#key-0-2| > 2]] |-id=key-0-2 |2 |Phyllaries appressed |[[Herrickia glauca|Herrickia glauca]] |-id=key-0-2 |2 |Phyllaries squarrose or spreading |[[#key-0-3| > 3]] |-id=key-0-3 |3 |Perennials; leaves ± clasping, entire, eglandular |[[Herrickia wasatchensis|Herrickia wasatchensis]] |-id=key-0-3 |3 |Subshrubs; leaves cordate-clasping, spinulose-serrate, glandular |[[Herrickia horrida|Herrickia horrida]] |} </div></div><!-- -->{{#Taxon: name=Herrickia |author=Luc Brouillet |authority=Wooton & Standley |rank=genus |parent rank=tribe |synonyms=Eurybia sect.
