Flora of North America species comparison

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

1–5+, ascending to erect, hirtellous-puberulent in arrays.

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 petiolate, tapering;

blades spatulate to oblanceolate, 20–150 × 5–40 mm, margins ciliate, serrate crenate, apices acute to rounded, faces glabrous;

distal usually 2–5, sessile, blades sometimes ± clasping, oblanceolate, 20–40 × 4–9 mm, distally reduced and becoming broadly to narrowly lanceolate, margins entire, apices acute to obtuse.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

5–6 mm, moderately hispidulo-strigillose;

bracteoles 0–1, linear-lanceolate.

campanulate, 4.5–5.5 mm.

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

unequal, outer (lengths 1/2 inner) deltate, acute, inner lanceolate, 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.

2–50(–160) in compact corymbiform arrays in smaller plants, corymbiform to paniculiform arrays in larger ones.

(reddish brown) 2–3 mm, glabrous;
