basal usually withering by flowering, long-petiolate, petioles sheathing, sparsely ciliate, blades lanceolate, 40–110 × (3–)5–7 mm, bases attenuate, margins entire to crenulate, rarely with 1–2 teeth, apices obtuse to rounded, callus-pointed;

proximalmost cauline sometimes withering by flowering, winged-petiolate or sessile distally, blades lanceolate to linear-lanceolate, 50–120(–180) × 1–6 mm, bases attenuate, margins entire, sparsely ciliate, apices acute;

distal sessile, blades subulate to lanceolate, 10–50 × 1–2 mm, bases clasping, apices acuminate.

(grayish green) firm, margins entire;

basal withering by flowering, sessile, blades (1–3 nerved) elliptic-lanceolate, 20–40 × 10–20 mm, bases attenuate, margins usually entire, rarely remotely serrate, piloso-ciliate, apices acute to obtuse, faces piloso-scabrous;

proximal cauline withering by flowering, sessile, blades oblanceolate, 20–30 × 5–13 mm, reduced distally, bases rounded, subclasping, margins entire, scrabrous, apices acute to obtuse, cuspidate-mucronate, faces glabrous or moderately strigose or ± scabrous;

distal sessile, blades oblong-lanceolate, 15–25 × 4–6 mm, bases cuneate, margins entire, apices acute, white-spinulose, faces glabrate to moderately strigose or ± scabrous.

1–4(–6) cm, ascending, glabrate, bracts 1–4(–5), subulate to lanceolate, foliaceous.

glabrous or sparsely strigose, bracts oblong-lanceolate, grading into phyllaries.
