Flora of North America species comparison

1–10, ascending to erect, uniformly finely strigillose-villous distal to mid.

1–5+, erect, glabrous proximal to arrays.

basal cauline nearly always withering well before flowering, linear-oblanceolate, smaller than proximal mid cauline, serrate;

proximal persisting, sometimes brown-black after senescence, often twisted;

proximal to distal numerous (100+ on tall stems), crowded, sessile, blades (bright green) linear to linear-lanceolate, 20–70 × 2–7(–10) mm, margins remotely serrulate (proximal) to entire or with 1–2 minute serrations (distal), obscurely 3-nerved, one or both faces glabrous or finely strigillose.

basal and proximal cauline tapering quickly to long, winged ciliate-margined petioles, blades ovate, 50–200 × 20–100 mm, margins serrate;

mid to distal cauline sessile, blades oblanceolate, 30–100 × 8–35 mm, reduced distally and becoming lanceolate-ovate, margins entire, abaxially sparsely strigose along nerves.

1–4 mm, finely strigilloso-villous;

bracteoles 0–2, linear, grading into phyllaries.
