--><span class="statement" id="st-undefined" data-properties=""><b>Leaves:</b> basal (rosettes) usually present at flowering, largest; petiole bases or vasculature persisting on rhizomes; proximalmost cauline petiolate, often present but withered at flowering; proximal and distal usually with 1 prominent nerve (multiple nerves proximally in <i>S. riddellii</i>). <b>Heads</b> in flat-topped to rounded corymbiform arrays, sometimes glomerulate. <b>Phyllaries</b> striate with 3–7 nerves (except <i>S. ptarmicoides</i>), eglandular. <b>Pappi</b> bristles in 2 series (outer not clavate, inner longest, somewhat to strongly clavate).</span><!--
