1–25 (–50+), erect, proximally glabrous or sparsely to moderately canescent-villous, distally densely so.

1–5+, erect, puberulent.

basal 0;

proximal cauline sessile, blades narrowly to broadly oblanceolate, 100–150 × 15–23 mm, tapering to bases, margins subentire to coarsely sharply serrate, 3-nerved, sometimes obscurely so, apices acute to acuminate, abaxial faces glabrate to sparsely short villous, adaxial glabrous;

mid to distal cauline sessile, blades lanceolate to narrowly elliptic, (50–)90–120(–150) × (7–) 11–23(–35) mm, largest near mid stem, then somewhat reduced distally in arrays, margins sharply and coarsely to finely serrate or entire, usually becoming less serrate near arrays, faces glabrous or sparsely strigoso-villous, more so along abaxial nerves, distalmost (below arrays) sometimes sparsely to moderately minutely stipitate-glandular.

basal and proximal cauline tapering to long petioles, blades oblanceolate to obovate, 50–150 × 10–50 mm, margins serrate, apices acute, faces puberulent;

mid to distal cauline sessile, blades lanceolate to linear-elliptic, 10–50 × 3–10 mm, reduced distally, margins becoming entire, apices acute.

1–4 mm, villoso-hirtellous, sometimes minutely stipitate-glandular;

bracteoles 0–2, linear-lanceolate, sometimes minutely stipitate-glandular.

in 3–4 series, deltate-lanceolate, unequal (outer 1/4–1/2 length of inner), margins sparsely villoso-ciliate, sometimes minutely stipitate-glandular apically or basally, apices acute to attenuate, glabrous or sparsely to moderately, minutely stipitate-glandular apically, sometimes over much of faces.
