distal sessile, blades linear-oblanceolate to -lanceolate or oblong (distally), 20–50 × 2–5 mm, ± reduced distally, bases ± clasping to cuneate, apices acute, mucronulate, faces glabrous or moderately short-strigose, stipitate-glandular.

(yellowish to dark green) thin, margins entire;

basal sometimes persistent, sessile, blades (3-nerved) oblanceolate to spatulate, 20–50(–70) × 5–15 mm, margins entire (remotely serrate), coarsely ciliate, apices rounded, short-mucronate, faces usually hirsute, rarely glabrous, often also stipitate-glandular;

proximal cauline sessile (often with clusters of smaller leaves in axils), blades oblong or linear-lanceolate, (15–)30–100 × 5–15(–20) mm, bases rounded or slightly clasping, margins scabrellous, apices acute to obtuse, spinulose-mucronate, abaxial faces scabrous, often stipitate-glandular, adaxial hirsute;

distal sessile, blades lanceolate to oblong, 20–80 × 2–10(–20) mm, greatly reduced distally, bases cuneate to subclasping, margins ciliate, stipitate-glandular, apices acute to obtuse, white-mucronate, faces moderately strigose, moderately to densely stipitate-glandular.

sparsely to moderately short-strigose, moderately stipitate-glandular, bracts ± ascending, linear to narrowly-lanceolate.

0.5–5 cm, hispid, stipitate-glandular, bracts dense, spreading or squarrose (rarely ascending), linear to narrowly oblong, 3–8 mm, grading into phyllaries, spinulose, short-strigose.

campanulate to cylindro-campanulate, 5.5–8 mm.

campanulate, (5–)7–9 mm.

15–31;

corollas violet, laminae (5–)6–15 × 1–2 mm.

corollas light to dark rose-purple, lavender to deep purple, laminae 9–13(–15) × 1–2 mm.

25–40;

corollas yellow, 4.5–6 mm, lobes triangular, 0.4–0.8 mm.

(25–)30–40(–50);

corollas yellow turning brown or reddish purple, 4.5–5.5(–6) mm, tubes 1/2 the funnelform to nearly tubular throats, lobes triangular, 0.4–0.7 mm.

in 3–4 series, linear to lanceolate, subequal to unequal, bases ± indurate, margins scarious, green zones covering distal portion, apices acute to acuminate, outer ± foliaceous, spreading to reflexed, faces glabrate, sparsely to densely stipitate-glandular.

in 4–5(–6) series, outer oblanceolate, mid linear-lanceolate, inner linear, usually unequal, sometimes subequal, bases ± indurate, margins hyaline, scarious, erose, ciliate or ciliolate and/or stipitate-glandular, green zones often broadly foliaceous (outer), green in distal 1/3–1/2 (mid), apices spreading to reflexed (outer), acute, mid long-acuminate, faces moderately hairy, stipitate-glandular.

1–10(–30), borne singly or in paniculiform arrays, branches ascending.

in ample, corymbiform to diffusely paniculiform arrays, branches initially patent, then ascending (often from proximal nodes).

light brown, sometimes translucent reddish brown between ribs, narrowly obovoid, ± compressed, 2–2.5 mm, 3–4-nerved (faint), moderately strigose on ribs;
