Flora of North America species comparison

1–10+, erect, glabrous.

1–6, decumbent to ascending, finely and densely puberulent.

basal and proximal cauline usually withering by flowering (other rosettes may be present), tapering to long, winged petioles, blades often recurved, linear- lanceolate or -oblanceolate, 100–240 × 8–16 mm, folded along midrib (V-shaped in cross section), bases usually with (2–)3–8 prominent lateral nerves, apices acute to obtuse, faces glabrous;

mid to distal cauline sessile, blades recurved, linear-lanceolate, 50–70 × 8–11 mm, reduced distally, folded, bases with prominent lateral nerves.

basal present at flowering;

basal and proximal petiolate, blades oblanceolate to narrowly obovate or spatulate, 20–100 × 5–20 mm, basal much smaller than proximal, margins serrate or entire, somewhat 3-nerved, apices obtuse to acute, cuspidate, faces moderately to densely finely puberulent;

mid and distal cauline sessile, blades oblanceolate to elliptic to base, 1 prominent nerve, 10–30 × 4–12 mm, greatly reduced distally, attenuate, margins entire or distally serrate, apices acute, faces densely finely puberulent.
