Flora of North America species comparison

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

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

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 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.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

2–7 mm, moderately puberulent;

bracteoles 0–2, elliptic, minute.

campanulate, 4.5–5.5 mm.

campanulate, 4–6 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

laminae ca. 3 × 1.3–1.6 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

8–20;

corollas 4–4.5 mm, lobes 0.8–1.1 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, oblong, strongly unequal, margins ciliate, apices blunt, glabrous.

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.

30–100, in broadly corymbiform (modified paniculiform) arrays, sometimes somewhat secund.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(narrowly obconic) 2–2.8 mm, sparsely strigose;

pappi 3.5–4 mm.
