Flora of North America species comparison

1–10+, erect, glabrous.

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

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 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.

2.8–4 mm, moderately short-hispido-strigose, lanceolate bracteoles 0–1.

2–6 mm, finely strigose;

bracteoles 1–10, often crowded, linear-lanceolate, 2–3 mm, grading into phyllaries.
