Flora of North America species comparison

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

1–4, erect, straight, glabrous or moderately hirtello-strigose.

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 to mid cauline weakly petiolate or sessile, blades lanceolate to elliptic, (36–)95–150(–180) × (10–)19–43(–60) mm, margins serrate (with (3–)8–20(–36) teeth), faces glabrous or sparsely hairy, more so along nerves;

distal cauline sessile, blades narrowly lanceolate to narrowly elliptic, (5–)37–90(–130) × (3.5)5–18(–34) mm, margins entire to sparsely serrate (0–9(–14) teeth), faces glabrous or sparsely hairy, sometimes more pilose along nerves.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

2–6 mm, moderately to densely finely strigose;

bracteoles 0–3, linear-oblong.

campanulate, 4.5–5.5 mm.
