proximal cauline sessile or subpetiolate, blades elliptic to obovate, 35–120 × 8–25 mm, bases attenuate or cuneate to rounded, sometimes ± clasping, apices acute;

distal sessile, reduced distally, bases cuneate, apices acute.

thin, margins coarsely, sharply serrate to crenate-serrate or serrulate, ciliate to scabrous, apices acute or acuminate, mucronulate, abaxial faces glabrate to sparsely hirsute, midveins usually densely hirsute, sometimes glabrous, adaxial glabrous or glabrate to scabrellous;

basal usually withering by flowering (sometimes persistent on small plants), long-petiolate (petioles slightly winged, sheathing, ciliate), blades ovate, (24–)40–120(–270) × 15–70 mm, bases usually shallowly cordate, sometimes rounded;

proximal cauline often withering by flowering, winged-petiolate, blades ovate to oblanceolate or lanceolate, (24–)60–150 × (10–)20–60 mm, reduced distally, bases subcordate to cuneate;

distal sessile or sometimes subsessile (petioles widely-winged), blades lance-ovate to linear-lanceolate or linear, 18–75 × (2–)5–25 mm, bases cuneate, sometimes ± clasping, margins serrulate or entire.

sparsely hairy, bracts 0–3, lanceolate.
