Flora of North America species comparison

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

usually 1, erect, glabrous, sparsely hairy 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 when present similar to proximal cauline;

proximal cauline often withering by flowering, tapering (sometimes rather abruptly) to short, winged petioles, blades ovate-lanceolate, 60–100(–150) × 30–40(–50) mm, thin, margins coarsely serrate, apices acute, abaxial faces hirsute on main nerves, adaxial sparsely hirsute to somewhat scabrous;

mid to distal cauline subsessile to sessile, blades lanceolate, 20–50 × 5–20 mm, gradually reduced distally, margins entire.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

1.7–2 mm, sparsely to moderately short hispido-strigose, bracteoles 2–7, ovate, grading into phyllaries.

campanulate, 4.5–5.5 mm.

3–4 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

3–6;

laminae 1–2 × 0.5–1 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

4–7;

corollas 2.7–3 mm, lobes 0.5–1.1 mm.

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

(16–18) in 2–3 series, unequal;

outer ovate, acute, inner linear-lanceolate, obtuse to acute.

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.

20–150, secund, in open paniculiform arrays, proximal branches elongate and widely divergent, sometimes pyramidal-secund with proximal branches short and recurved-secund.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

1–1.6 mm, finely hairy;

pappi ± 2.5 mm.
