Flora of North America species comparison

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

usually single, erect, essentially glabrous basally to hispidulo-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 tapering to long, winged petioles (quickly reduced distally on stems), blades broadly oblanceolate to obovate, 40–150 × 15–50 mm, margins serrate, finely ciliate, apices acute to obtuse, faces glabrous;

mid and distal cauline sessile, blades linear-elliptic, 5–50 × 2–10 mm, margins entire, finely ciliate.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

1–3 mm.

campanulate, 4.5–5.5 mm.

narrowly campanulate, 3.5–6.5 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

5–9;

laminae 2.5–3.5 × 0.7–1 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

commonly 6–10;

corollas 4 mm, lobes ca. 1 mm.

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

in 3–5 series, appressed, strongly unequal, outer ovate, inner broadly oblong, obtuse to rounded, 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.

15–350 (1–10 per branch), clustered on short divergent lateral branches in elongate and usually narrowly paniculiform arrays, often interrupted proximally, not secund, sometimes with ascending, straight or arching, elongate branches (like main axis).

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(tan) ca. 2.5 mm, glabrous;

pappi 3 mm.
