1–10+, decumbent to ascending or erect (grayish brown, slender), sparsely strigoso-hispid, ± scabrous.

thin, margins entire (basal sometimes serrulate), sometimes ciliate or remotely scabrous, acute to ± obtuse, faces glabrous;

basal withering by flowering, petiolate, blades oblanceolate to spatulate, 20–115 × 2–15 mm [cult.], bases attenuate;

proximal cauline withering by flowering;

cauline subpetiolate or sessile (distal), blades oblanceolate to linear, 10–80 × 1.5–10 mm, reduced distally, bases cuneate.

(dark bright green) firm, much reduced distally, margins entire, apices acute, mucronate, faces usually glabrous, sometimes sparsely strigoso-hispid;

basal withering by flowering (new vernal rosettes often present), sessile, blades (1–3-nerved) linear-oblanceolate, 20–40 × 5–30 mm, bases attenuate, margins scabro-ciliate;

proximal cauline sometimes persistent, sessile, blades linear to linear-lanceolate, 10–40 × 5–20 mm, bases sometimes subclasping, margins entire, scabrous;

distal sessile, blades linear to linear-lanceolate, 20–40 × 2–3 mm, bases cuneate, margins entire, coarsely cililate-spinulose, apices acute, white-spinulose, faces sometimes stipitate-glandular.

glabrous, bracts linear.

sparsely hispido-strigose, ± densely stipitate-glandular, bracts ± ascending, linear to lance-oblong, grading into phyllaries.

narrowly campanulate, 5–9 mm.

campanulate, 4–7 mm.

90–110 in 4–5+ series;

corollas pink to pinkish white, laminae 1.5–2 × 0.1–0.2 mm (surpassing style branches, barely surpassing disc corollas; tubes ± 3 mm).

10–20;

corollas light to dark lavender to purple, laminae 5–10 × 1–2 mm.

± 37;

corollas yellow, 4.4–5.2 mm, barely ampliate, tubes much longer than cylindric limbs, lobes lanceolate, ± 0.3 mm.

(7–)10–30;

corollas yellow becoming reddish purple, 3.5–5 mm, throats narrowly funnelform, lobes narrowly triangular, 0.4–0.7 mm.

in 3–4 series, ± spreading, oblong-oblanceolate or -lanceolate to obovate, subequal to ± unequal, linear-lanceolate or linear (innermost), bases scarious, margins narrowly scarious, hyaline, erose, ciliolate, green zones (outer) foliaceous, (inner) lanceolate, apices obtuse to rounded, inner acute, mucronulate, faces glabrous.

in 3–4 series, lanceolate, unequal, bases ± indurate, margins narrowly to widely scarious, hyaline except apically, sometimes ciliolate, often stipitate-glandular, green zones lanceolate to diamond-shaped, covering distal portion (outer), apices acuminate, spreading to reflexed, faces glabrous, moderately to densely short-stipitate-glandular.

(radiate) in narrow, paniculiform to spiciform arrays, branches often in axils of nearly every leaf, ascending.

in ± narrowly racemiform to paniculiform arrays, branches sometimes initially patent, then spreading to ascending.
