--><span class="statement" id="st-undefined" data-properties=""><b>Perennials </b>or subshrubs, 1–70 cm (rhizomes elongate and slender to short and thick, often becoming woody, or woody caudices). <b>Stems</b> ascending to erect, usually simple, rarely branched proximally, glabrous or thinly scabridulous, sometimes stipitate-glandular (mostly distally). <b>Leaves</b> mostly basal or mostly cauline; alternate; sessile or petiolate; blades 1-nerved, oblanceolate to spatulate, distal usually gradually reduced, margins entire or spinulose-serrate, faces glabrous or scabrellous, sometimes stipitate-glandular. <b>Heads</b> radiate, in corymbiform arrays or borne singly. <b>Involucres</b> cylindro- to hemispherico-campanulate, (6–12 ×) 5–10 mm. <b>Phyllaries</b> 15–40+ in 3–6 series, 1-nerved (low-keeled or rounded adaxially), spatulate, oblanceolate, oblong-obovate, oblong, ovate, lanceolate, or linear-lanceolate, unequal, bases indurate, margins narrowly scarious (sometimes foliaceous), often ciliolate; green zones ± basally truncate, usually in distal 1/5–9/10, rarely wholly foliaceous (outer) to less than 1/6 and only along midveins (inner); (apices acute to long-acuminate), faces glabrous, usually stipitate-glandular. <b>Receptacles</b> flat to slightly convex, pitted, epaleate. <b>Ray</b> florets 8–27, pistillate, fertile; corollas white to purple (coiling at maturity). <b>Disc</b> florets 12–43, bisexual, fertile; corollas yellow, becoming purple at maturity, barely ampliate, tubes shorter to longer than funnelform to campanulate throats, lobes 5, erect to spreading, triangular or lanceolate; style-branch appendages lanceolate. <b>Cypselae</b> cylindro-obconic to fusiform, ± compressed, 7–10-nerved, faces glabrous or densely strigillose, eglandular; pappi persistent, of 35–70+, yellowish to cinnamon or tawny, unequal, ± stiff, barbellate, apically attenuate or (longer) sometimes ± clavate bristles in 1+ series. <b>x</b> = 9.</span><!--

--><p>G. 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>
