    Plants (2–) 10–50 cm, clonal and clumped, eglandular;
    rhizomes creeping to ascending, long or short, scaly, woody with age.
    Stems 1–3+, usually ascending, sometimes decumbent, purplish, occasionally branched basally, sparsely villosulous, densely so distally.
    Leaves cauline (dark green abaxially, paler bluish green adaxially) firm, ± markedly veined, margins entire or serrulate, scabrous to strigoso-ciliate, teeth mucronate, slightly indurate, apices obtuse to acute, mucronate, abaxial faces glabrescent to sparsely villous along veins, adaxial glabrescent or sparsely (proximal) to ± densely (distal) villoso-strigose or strigose;
    proximalmost withering by flowering;
    proximal narrowly winged-petiolate or sessile, petiole bases sheathing, blades spatulate to obovate or oblanceolate, 10–43 × 2–16 mm, smaller than mid, bases attenuate to cuneate, subclasping (if sessile);
    mid sessile, blades lanceolate or oblong-lanceolate to oblanceolate, narrowly obovate, or spatulate, 20–80 × 4–35 mm, gradually reduced distally, bases rounded or subauriculate to widely attenuate or cuneate;
    distal (arrays) sessile, lanceolate to lanceovate or elliptic to oblanceolate, 6–52 × 1–17 mm, rapidly reduced distally, margins often slightly purplish.
    Heads (1–) 5–50, usually in open to compact, corymbiform arrays, rarely borne singly.
    Peduncles villosulous;
    bracts 0–3, lanceolate to spatulate, leaflike to distally phyllary-like (bases indurate, margins purplish), mostly foliaceous.
    Involucres campanulate, 6–9 mm, shorter than pappi.
    Phyllaries 30–65 in 4–5 series, often purplish, oblong or lance-oblong (outer) to lance-linear or linear (inner), unequal, membranous, bases indurate, rounded, dark green zones diffusely diamond-shaped to lanceolate in distal 1/3–2/3 (outer, seldom foliaceous) to 1/5 or none (inner), margins ± dark purple, narrowly scarious, erose, densely villoso-ciliate, apices appressed or sometimes loose and ± squarrose, acute to obtuse, often apiculate, faces usually villous, rarely glabrous.
    Ray-florets (10–) 14–32;
    corollas purple to violet, 7–12 (–15) × 1–1.7 mm.
    Disc-florets 30–60;
    corollas pale to cream-yellow, lobes pink-tinged, 5–7.6 mm, slightly ampliate, tubes equaling or slightly longer than funnelform throats, lobes erect, triangular, 0.6–1.3 mm.
    Cypselae brownish, fusiform-obconic, slightly compressed, ca. 3.4 mm, ribs 8–10 (pale, strong), strigillose;
    pappi of cinnamon to yellowish bristles 5–6 mm, longer than disc corollas.
