Flora of North America species comparison

usually 1–3, ascending to erect, scabrous to loosely puberulent.

single (sometimes purplish brown, ridged), glabrous, strigose distally in arrays.

basal and proximal usually withering by flowering, tapering to long-winged petioles, blades oblanceolate, 30–100 × 7–20(–30) mm, margins serrate or crenate, mid usually largest, apices acute to obtuse, acuminate, faces scabrous;

mid and distal cauline subsessile (1 mm) or sessile, blades (sometimes ± shiny) elliptic to oblanceolate, 10–50 × 5–15(–25) mm, greatly reduced distally, grading into bracts, firm, bases convex-cuneate to rounded, margins finely serrate, often 3-nerved, nerves usually distinct abaxially, faces distinctly scabrous.

basal and proximal tapering to winged petioles, blades (basal) spatulate, 20–40 mm, (proximal) obovate to oblanceolate or elliptic, 60–150(–200) × 30–55 mm, margins serrate (teeth shallow to 5 mm), ciliate, acute to obtuse, acuminate or mucronate, faces abaxially glabrate to sparsely strigose, especially on nerves, adaxially glabrous;

mid and distal cauline sessile, lancelate or oblanceolate to elliptic, 30–100 × 20–40 mm, reduced distally, margins serrate to entire distally.
