1–20+, erect, proximally sparsely to moderately strigoso-villous, distally usually moderately to densely so.

1–20, erect, finely scabroso-puberulent, sparsely so with age proximally, densely so distally.

basal 0;

proximal cauline sessile, blades narrowly to broadly oblanceolate, 35–75(–100) × (6–)7.5–14(–20) mm, proximal much smaller, tapering to bases, margins subentire or finely serrulate to coarsely, sharply serrate (teeth 0–9 per side), ciliate, 3-nerved, sometimes obscurely so, apices acute, abaxial faces glabrate to sparsely short-strigose, adaxial glabrous;

mid to distal cauline sessile, blades oblanceolate, becoming lanceolate distally, 20–60 × 4–8(–11) mm, largest near mid stem, somewhat to much reduced distally, margins entire or finely serrulate, rarely serrate (teeth 1–8 per side), usually becoming entire to sparsely serrulate distally, ciliate, apices acute, faces glabrous or sparsely strigoso-villous, more so along abaxial nerves.

basal and proximal cauline withering by flowering, subsessile, gradually tapering to short-winged petiole-like bases;

mid and distal cauline sessile, blades linear-elliptic to linear-lanceolate, 40–90 × 4–5 mm, 3-nerved from base, midnerves prominent, margins entire, finely scabrous, apices attenuate-acute, faces finely, sparsely to moderately strigose, more so on main nerves, finer nerves translucent, faces sometimes shiny.
