--><span class="statement" id="st-undefined" data-properties=""><b>Annuals </b>or perennials, 5–80 cm (usually fibrous-rooted, sometimes rhizomatous, usually stoloniferous). <b>Stems</b> usually 1, erect. <b>Leaves</b> basal and cauline (sometimes in rosettes); alternate; petiolate or sessile; blades oblanceolate, spatulate, lanceolate, or linear, bases cuneate or ampliate, margins entire (sometimes undulate and/or revolute), faces bicolor, abaxial usually silvery, tomentose, adaxial usually green, glabrate or glabrous. <b>Heads</b> disciform, usually in terminal clusters (subtended by leafy bracts, sometimes with axillary clusters), rarely borne singly. <b>Involucres</b> narrowly campanulate to cylindric, 3–5 mm. <b>Phyllaries</b> in 3–4+ series, mostly stramineous to brownish, sometimes purplish to pinkish (hyaline, stereomes not glandular), unequal, chartaceous toward tips. <b>Receptacles</b> flat, smooth, epaleate. <b>Peripheral</b> (pistillate) florets 16–150 (more numerous than bisexual); corollas purple or distally purplish. <b>Inner</b> (bisexual) florets 1–7; corollas purple or distally purplish. <b>Cypselae</b> obovoid-ellipsoid, slightly flattened, faces minutely hairy or papillate (papilliform hairs or papillae ± clavate, not myxogenic); pappi readily falling (singly or in groups), of 12–20, distinct or basally coherent, barbellate bristles in 1 series. <b>x</b> = 14.</span><!--
