Flora of North America species comparison

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

1–10+, erect, stout, hairy.

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 and proximal cauline usually present at flowering, abruptly narrowed to long petioles, blades ovate to rhombic, 80–200 × 24–50 mm, firm, flat, margins entire to crenate, sometimes undulate, apices obtuse to acute, faces densely hairy;

mid to distal cauline sessile, blades ovate, 30–50 × 15–17 mm, stiff, greatly reduced distally, margins entire or finely serrate, sometimes undulate, apices acute to obtuse.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

3–15 mm, strigillose-canescent, bracteoles 1–3, linear-lanceolate.

campanulate, 4.5–5.5 mm.

campanulate, 6–8 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

6–13;

laminae 1.4–5.4 × 1.2–1.9 mm.

corollas 4.3–6.1 mm, lobes 0.6–1.1 mm.

in ca. 3 series, strongly unequal, erect to slightly squarrose-tipped, lanceolate, apices acute, glabrate, sparsely to moderately, finely stipitate-glandular.

in 3–4 series, unequal, oblong, conspicuously striate (3–5 pronounced nerves), obtuse.

5–160 (2–10+ more per short branch cluster), in narrowly elongate paniculiform arrays, branches usually 1–6 cm (much longer in damaged plants, sometimes 1–3 proximal branches much elongated in undamaged plants), ascending and bearing short terminal racemiform or paniculiform clusters.

9–190, in corymbiform arrays, compact or branches long and spreading, densely hairy throughout.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(obconic) 0.8–1.7 mm (ribbed), glabrous or strigillose apically;

pappi 3–4 mm.
