--><span class="statement" id="st-undefined" data-properties=""><b>Annuals,</b> biennials, or perennials, 10–40 cm; fibrous-rooted. <b>Stems</b> erect to ascending (commonly decumbent-ascending and rhizome like), densely white-pannose. <b>Leaves</b> basal and cauline, basal usually withering before flowering, blades spatulate to oblanceolate, 2–5 cm × 6–12(–35) mm (little smaller distally), faces bicolor, abaxial white-pannose, adaxial sparsely to densely arachnose-tomentose. <b>Heads</b> in usually continuous, rarely interrupted (proximally), cylindric arrays 1–6(–8+) cm × 12–18 mm (pressed). <b>Involucres</b> campanulo-urceolate, 4.5–5 mm, bases sparsely arachnose. <b>Phyllaries</b> in 4–6 series, outer (brown or greenish brown) broadly ovate-triangular, lengths ca. 1/2 inner, apices acute to acute-acuminate (mid phyllaries ± keeled near apices), inner oblong, laminae usually dark brown, sometimes purplish (at stereome-lamina junction), apices rounded to obtuse, apiculate. <b>Florets</b>: bisexual (3–)4–6; all corollas usually yellowish, sometimes purplish distally. <b>Cypselae</b> (tan to brownish) 0.7–0.8 mm.</span><!--
