Flora of North America species comparison

1–5+, sparsely to moderately short strigose or villous.

1–5+, erect, straight, moderately hairy in arrays.

basal withering by flowering, petiolate, smaller to much smaller than cauline, blades oblanceolate, margins serrate;

cauline sessile, blades elliptic-lanceolate or -oblanceolate, mid 80–140 × 2.5–4 mm, distally reduced, usually membranous, bases tapering, attenuate, margins sharply toothed along much of length to nearly entire, ciliate, abaxial faces short-pilose along small and large nerves, adaxial short-pilose along larger nerves.

basal withering by flowering;

proximal cauline subpetiolate or sessile, tapering to broadly winged petiole-like bases, blades lanceolate, 110–180 × 2–35 mm, margins serrate (with 7–15 teeth), apices acuminate, abaxial faces sparsely hairy along nerves, adaxial glabrous or sparsely hairy;

distal cauline sessile, blades narrowly elliptic, 60–110 × 11–15 mm, margins entire to slightly serrate (teeth 0–6), apices acuminate-cuspidate, faces glabrous or sparsely hairy.
