basal withering by flowering, sessile, blades (1–3-nerved) elliptic-lanceolate, 10–43 × 5–15 mm, bases attenuate, margins usually entire, rarely remotely serrate, piloso-ciliate, apices acute to obtuse, faces silvery silky-pilose to sparsely pilose;

proximal cauline withering by flowering, sessile, blades oblanceolate, 20–35 × 5–15 mm, bases rounded, subclasping, margins entire, scabrous to silky-pilose, apices acute to obtuse, cuspidate mucronate, faces ± densely silky;

distal sessile, blades usually oblong to lanceolate, rarely ovate, 9–15 × 1.8–5 mm, reduced distally, bases cuneate, margins entire, apices acute, mucronate, faces ± densely silky or sparsely strigose, sometimes glabrate (var. devestitum).

thin, margins entire to serrate, apices acute, faces scabrous;

basal withering by flowering, petiolate, blades elliptic to obovate 30–300 × 15–50 mm, attenuate, margins entire to serrate, apices acute, faces rough-hispidulous;
