--><span class="statement" id="st-undefined" data-properties=""><b>Annuals </b>or perennials, 10–80(–150+) cm. <b>Stems</b> erect, branched (mostly distally). <b>Leaves</b> cauline; opposite (proximal) or alternate (mostly); petiolate or sessile; blades (1- or 3-nerved) broadly lanceolate to linear, margins entire, faces sparsely to moderately scabrellous to strigillose or appressed-puberulent (hairs 0.1–0.8+ mm), not gland-dotted. <b>Heads</b> radiate, discoid, disciform, or radiant, in ± corymbiform arrays. <b>Involucres</b> narrowly cylindric or turbinate to hemispheric, 3–15+ mm diam. <b>Phyllaries</b> persistent or falling (in fruit), 8–14 in 2–3 series (erect in flowering, reflexed in fruit, purplish, or whitish, linear to oblanceolate, subequal or unequal, herbaceous to membranous). <b>Ray</b> florets 0, or 3–13, pistillate, fertile; corollas white or pinkish to purplish. <b>Disc</b> florets 12–40(–90), bisexual, fertile; corollas pinkish to purplish or whitish (glabrous or sparsely hairy, sometimes stipitate-glandular), tubes shorter than cylindric throats or much longer than short, broadly funnelform throats, lobes 5, lance-linear or linear (equal or unequal). <b>Receptacles</b> flat, pitted or knobby, epaleate. <b>Cypselae</b> obpyramidal, 4-angled, densely to sparsely hairy (hairs straight); pappi usually persistent, of 4–10 rotund and callous-thickened, or spatulate to subulate, medially thickened, laterally scarious scales in 1–2 series (all, some, or none aristate, all alike or pappi of outer cypselae shorter, rarely 0). <b>x</b> = 12.</span><!--

--><p>Circumscriptions of species adopted here closely follow those of B. L. Turner and M. I. Morris (1976). Some of their circumscriptions, especially those of <i>Palafoxia callosa</i>, <i>P. rosea</i>, and <i>P. texana</i>, merit reconsideration and possibly different interpretations. Their infraspecific taxa are not formally recognized here.</p>
