    in extensive, dense clones (with abundant, sterile rosettes);
    rhizomes branched, herbaceous.
    Stems 1, erect, simple, straight to ± flexuous, glabrous or sparsely villous, stipitate-glandular, more densely so distally (at least in arrays).
    Leaves basal and cauline, thick, firm, margins coarsely serrate (proximal) to crenate-serrate or entire (distal), scabrous, teeth mucronate, apices acuminate, sharply mucronate, abaxial faces glabrescent to sparsely strigose, veins stipitate-glandular, adaxial sparsely strigose, ± densely villous on veins, short-stipitate-glandular (more so on distal);
    basal withering by flowering, petioles (25–) 80–170 mm, ± winged, bases sheathing, ciliate, blades broadly ovate, (45–) 110–250 × (25–) 55–150 mm, bases deeply cordate (sinuses curved), sometimes slightly oblique;
    cauline petiolate (3–110 mm), gradually more broadly winged and sometimes ± auriculate distally, ± clasping, ciliate, to subpetiolate or sessile, blades broadly ovate to ovate, 22–104 × 9–80 mm, gradually reduced distally, bases cordate to rounded or attenuate to cuneate;
    distal (arrays) sessile, blades ovate or broadly lanceolate or elliptic to obovate or oblanceolate, 9–38 × 3–13 mm, abruptly reduced distally, bases ± clasping to rounded or cuneate (arrays), margins crenate-serrate or entire.
    Heads (2–) 8–90+ in flat-topped, corymbiform arrays.
    Peduncles firm, 0–4 cm, densely stipitate-glandular;
    bracts 0–2, ovatelanceolate, ± stipitate-glandular.
    Involucres broadly campanulate to campanulate, (6–) 7–11 mm, shorter than pappi.
    Phyllaries 32–35 in 5–6 series, appressed, often purple-tinged, usually obovate to oblong, seldom ovate (outer) to oblanceolate or linear-lanceolate (inner) (innermost to 7 mm), strongly unequal, bases indurate, keeled or rounded adaxially, dark green zones wide, 1/3–1/2 distal portion (rarely to base in outer) to less pronounced along midveins or none (inner), margins hyaline or reddish, scarious, ± erose, densely villoso-ciliate apically, apices obtuse to rounded or acute (inner), adaxial faces ± villous, ± stipitate-glandular.
    Ray-florets 9–20;
    corollas ± deep lavender or violet to occasionally white, (7–) 11–15 × 1.4–2.4 mm.
    Disc-florets 20–40;
    corollas cream-color or light yellow, becoming purple, 6–7.5 mm, slightly ampliate, tubes (ca. 4 mm) longer than funnelform throats (ca 1.2 mm), lobes reflexed, lanceolate, 1–1.6 mm.
    Cypselae brown, fusiform or cylindro-obconic, compressed, 2.6–4.5 mm, ribs 7–12 (golden brown), faces glabrous or sparsely strigillose distally;
    pappi of tawny to orangish (sometimes clavellate) bristles 5–7.5 mm, slightly longer than disc corollas.
