Flora of North America species comparison

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

1–5+, glabrous, sparsely strigose 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 petiolate;

blades broadly elliptic to ovate, 100–350 × 60–120 mm (including petioles), bases truncate to obtuse, apices acute to acuminate, margins sharply serrate, glabrous;

distal cauline blades spreading to ascending, linear-elliptic, 30–50 × 6–15 mm.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

1.5–3 mm, glabrate to moderately short hispido-strigose, bracteoles 1–5, linear-lanceolate grading into phyllaries.

campanulate, 4.5–5.5 mm.

campanulate, (4.5–)5–7 mm (much exceeded by pappi).

6–8;

laminae 3–4 × 1–1.5 mm wide.

4–9;

laminae 4–5 × 1.5–2.5 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

9–11;

corollas 4–5 mm, lobes ca. 1.5 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, linear-lanceolate, strongly unequal.

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.

25–50+, in elongate, paniculiform arrays, proximal branches recurved-secund, sometimes elongate.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(brown, ribs dark brown) 3 mm, sparsely short-strigose;

pappi 3–4 mm.
