basal withering by flowering, petiolate, blades obovate to elliptic, 30–150 × 10–40 mm, bases cuneate to rounded, margins entire, ciliolate, apices acute, faces densely cinereous to lanate;

proximalmost cauline sometimes withering by flowering, subpetiolate or sessile, blades obovate-lanceolate to elliptic, 50–100 × 10–25(–35) mm, bases cuneate, clasping, ± auriculate, apices usually acute;

distal sessile, blades 20–60(–80) × 9–16(–20) mm, bases rounded to auriculate.

thin, margins scabrous, abaxial faces hirtellous, densely so on midveins, adaxial usually scabrous, sometimes strigose or hirsute, rarely glabrate;

basal withering by flowering (sometimes new winter rosette developing), petiolate (petioles purplish, narrowly winged, bases dilated and sheathing, hirsute), blades oblong-ovate or ovate to widely ovate, (10–)35–60(–140) × (10–)15–70 mm, bases usually cordate or subcordate to rounded, sometimes attenuate, margins shallowly crenate-serrate to subentire, apices obtuse or rounded, mucronulate;

proximalmost cauline withering by flowering, proximal persistent, winged-petiolate, distally more widely winged or ± sessile, wings widening abruptly at strongly auriculate-clasping petiolar bases, blades ovate to lanceolate, 30–120(–140) × (10–)20–50 mm, reduced distally, bases cordate- or auriculate-clasping (sessile), margins crenate-serrate or entire, apices acute or acuminate, mucronate;

distal sessile, blades lance-ovate to oblong or lanceolate to linear-lanceolate, sometimes pandurate (branch leaves ovate to lanceolate, sharply smaller), 4–100 × 0.5–26 mm, reduced distally, bases ± clasping, sheathing, margins serrulate or entire, apices acute or acuminate to long-acuminate.

densely lanate, bracts 1–8, elliptic, margins ciliolate, apices acute, puberulent.

well developed, 0.3–3(–5) cm, branches to 10 cm, spreading, bracteate, densely hirtellous to strigillose, bracts 3–10+, firm, appressed, subulate (2–3 mm), grading into phyllaries.

campanulate, 6–10 mm.

campanulate to cylindro-campanulate, 3.8–5.5 mm.

18–40;

corollas violet, laminae (8–)12–20 × 1–2(–2.5) mm.

35–80+;

corollas yellow, 6–9 mm, lobes triangular, 0.4–1 mm.

15–22(–25);

corollas cream or light yellow becoming purple, 4–5.8 mm, tubes slightly shorter than funnelform throats, lobes lanceolate, 0.5–0.9 mm.

in 4–6 series, oblanceolate (outer) to linear (inner), unequal, bases scarious (outer sometimes foliaceous), margins slightly scarious, entire, green zones obovate to elliptic, apices acute, faces densely lanate to cinereous.

in 4–5(–6) series, appressed or outer spreading, oblong-lanceolate (outer) to linear-oblanceolate (inner) or linear (innermost), strongly unequal, bases indurate 1/2–2/3, margins scarious, erose, hyaline, ciliolate, green zones diamond-shaped to lanceolate, apices acute to acuminate or obtuse, often ± involute, often mucronulate, sometimes tips purplish, abaxial faces hirsutulous, adaxial sparsely so distally.

in paniculiform, very leafy arrays, branches 4–10(–20) cm.

in open, narrow to wide paniculiform arrays, branches widely spreading, divaricate to ascending, sometimes secund, ± densely leafy.

brown, cylindric to obovoid, not compressed, 3.5–4.5 mm, 4–5-nerved, faces sparsely hairy;

pappi tawny, (6–)7–9 mm.
