sparsely to densely puberulent, puberulent-villous, or strigoso-puberulent.

glabrous (often sparsely sessile-glandular).

basal and proximal cauline 1-nerved, narrowly oblanceolate to spatulate-lanceolate, 90–150(–220) × 4–17(–24) mm, gradually reduced distally to near midstem, then abruptly reduced, linear or narrowly lanceolate, ascending to nearly erect, bractlike, sparsely to densely puberulent, ± gland-dotted.

basal (often withering before flowering), 1- or 3–5-nerved, linear-elliptic, linear-spatulate, or linear-oblanceolate, (170–)200–400 × 3–10 mm, gradually reduced distally, essentially glabrous, gland-dotted (proximal margins pilose-ciliate).

usually (5–)8–15(–30) mm.

0 or (spreading-ascending) 1–2 mm.

campanulate to turbinate-campanulate, 10–15 × 13–18 mm.

30–70;

corolla tubes glabrous inside.

9–17;

corolla tubes pilose inside.

in (3–)4–5 series, oblong-obovate to oblong-spatulate, strongly unequal, essentially glabrous, margins with (purple) hyaline borders, erose to lacerate or irregular, apices broadly rounded to truncate.

pappi: lengths ± equaling corollas, bristles barbellate.

ca. 4 mm;

pappi: lengths ± equaling corollas, bristles barbellate.
