--><span class="statement" id="st-undefined" data-properties=""><b>Perennials,</b> 5–120+ cm; herbage tomentose or glabrescent, not spiny. <b>Stems</b> erect or ascending, simple or branched. <b>Leaves</b> basal or cauline (sometimes cauline only), sessile or petiolate; blade margins entire or dentate to pinnately lobed, faces glabrous to densely tomentose, glandular or eglandular. <b>Heads</b> discoid, borne singly or in corymbiform arrays. <b>Involucres</b> ovoid to campanulate or ± turbinate. <b>Phyllaries</b> many in 3–5(–10+) series, subequal to strongly unequal, appressed or not, ovate to lanceolate, margins entire, toothed, or lobed, apices obtuse or acute, appendaged or not, not spine-tipped. <b>Receptacles</b> flat or convex, epaleate, smooth, usually subulate-scaly, sometimes bristly or naked. <b>Florets</b> 10–20; corollas white to blue or purple, tubes slender, abruptly expanded to throats, lobes linear; anther bases short-tailed, apical appendages linear, acute; style branches: fused portions with minutely hairy subterminal nodes, distinct portions oblong to linear, short-papillate. <b>Cypselae</b> oblong, ± angled, cylindric or 4–5-angled, ribs (when present) smooth or roughened, apices entire, glabrous or minutely glandular, attachment scars basal; pappi usually of 2 series, outer of readily falling, short bristles, inner persistent or falling as unit, of basally connate, usually longer, plumose bristles. <b>x</b> = 13, 14, 16, 17, 18, 19?.</span><!--
