--><span class="statement" id="st-undefined" data-properties=""><b>Perennials,</b> 5–60(–100) cm (taproots relatively massive; caudices sometimes branched). <b>Stems</b> erect and branched (mostly distally), or decumbent (and seldom branched distally). <b>Leaves</b> basal and cauline (basal usually scalelike on flowering stems, well-formed on non-flowering shoots); alternate; petiolate; blades (3-or 5-nerved or pinnately nerved), cordate-ovate, deltate, deltate-triangular, ovate, ovate-lanceolate, or suborbiculate, bases broadly cuneate, subcordate, or truncate, margins entire or dentate to crenate, faces glabrous or hairy (often gland-dotted). <b>Heads</b> radiate or discoid, borne singly (terminal) or in ± racemiform arrays. <b>Involucres</b> campanulate to ± hemispheric, 12–40 mm diam. <b>Phyllaries</b> persistent, (8–)12–26+ in 2–3+ series (subequal to unequal, outer usually surpassing inner). <b>Receptacles</b> flat to convex, paleate (paleae persistent, conduplicate, chartaceous). <b>Ray</b> florets 0 or (1–)5–21+, pistillate, fertile; corollas yellow. <b>Disc</b> florets 50–150+, bisexual, fertile; corollas yellow, tubes shorter than cylindric throats, lobes 5, lance-deltate (style branches stigmatic in 2, barely distinct lines, appendages filiform). <b>Cypselae</b> ± prismatic, 3–4-angled (faces glabrous or strigillose); pappi usually persistent, coroniform (± lacerate, sometimes with 1–4 teeth or scales), sometimes 0. <b>x</b> = 19.</span><!--
