basal withering by flowering, petiolate, blades narrowly lanceolate, 60–200 × 10–20 mm, attenuate or cuneate, margins usually entire, sometimes serrate, apices acute, faces glabrous or sparsely puberulent;

proximalmost cauline sometimes withering by flowering, sessile, blades narrowly lanceolate, 50–150 × 8–25 mm, bases cuneate, often auriculate, apices acute;

distal sessile, blades linear to narrowly lanceolate, 20–120 × 3–20 mm, bases cuneate, often auriculate, apices acute.

(grayish) soft;

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 silvery piloso-silky;

proximal cauline withering by flowering, sessile, blades oblanceolate, 20–30 × 4–8 mm, bases rounded, subclasping, margins entire, scabrous to silky-piloso-ciliate, apices acute to obtuse, cuspidate-mucronate, faces moderately strigillose;

distal sessile, blades lanceolate to narrowly ovate, 8–15 × 2.5–5 mm, reduced distally, bases cuneate, margins entire, apices acute, mucronate, faces moderately, finely lanoso-strigose.
