--><span class="statement" id="st-undefined" data-properties=""><b>Perennials,</b> 10–100(–120) cm, cespitose; with short, thick, woody caudices, tangled or sometimes cormoid, and long rhizomes. <b>Stems</b> 1–5+, ascending to erect (often stout, light to dark brown), sparsely to densely scabroso-hirsute to cinereo-puberulent, or villous distally. <b>Leaves</b> (light to dark green) thick and often stiff (margins flat, sometimes undulate), scabrous; basal early deciduous, subpetiolate (petioles winged, sheathing), blades spatulate to obovate, 30–70 × 10–30 mm, bases cuneate, margins entire to ± serrulate, scabrous, apices acute to rounded, faces scabroso-hirsute; proximal cauline sessile, blades usually ovate to lanceolate, rarely spatulate, (20–)30–70(–100) × 10–30(–40) mm, reduced distally, bases strongly cordate-clasping to auriculate-amplexicaul (broadened below constriction), apices acute, faces (grayish green) rugulose, hairy (abaxial inconspicuously veined, adaxial reticulately veined, hairier along veins); distal sessile, blades narrowly to broadly ovate, 15–35 × 4–13 mm, much reduced on branches, bases strongly cordate-clasping to auriculate-amplexicaul, apices usually acute, sometimes obtuse, mucronate to white-spinulose, faces scabrous, sometimes sparsely to moderately stipitate-glandular. <b>Heads</b> in paniculiform arrays, branches divaricate (heads 1–5+ per branch), terminal shoot often not flowering. <b>Peduncles</b> stiffly ascending, slender, 2–10(–15) cm, scabroso-hirsute to cinereo-puberulent, bracts appressed to spreading, linear, 1–5 mm, grading into phyllaries. <b>Involucres</b> campanulate, 5.5–12 mm. <b>Phyllaries</b> in 4–7(–8) series, appressed or often slightly recurved-spreading or squarrose, ovate-lanceolate to linear, strongly unequal, bases (tan) ± indurate in proximal 1/3–1/2, margins hyaline, erose, distally scabroso-ciliolate to ciliolate, green zones diamond-shaped, in distal 1/5–1/3, apices (outer) obtuse to acute, appressed to squarrose, (inner) acuminate, often purplish red, faces strigillose or cinereo-puberulent abaxially and near tip adaxially, sometimes moderately stipitate-glandular distally. <b>Ray</b> florets 12–24+; corollas light lavender-violet to mauve, rarely white to pinkish, laminae 10–18(–20) × 1–3 mm. <b>Disc</b> florets 20–50; corollas yellow, cream, or white turning purple, (4.5–)5.5–7.5 mm, tubes shorter than narrowly funnelform throats, lobes triangular, 0.5–1 mm (glabrous or lobes thinly puberulent). <b>Cypselae</b> dull purple or brown, obovoid to oblong-obovoid, not compressed, 2–3.5 mm, 7–10-nerved (faint), faces sericeous or strigillose; pappi tawny, sometimes rose-tinged, 4.5–6.5 mm.</span><!--
