Flora of North America species comparison

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

usually 1, erect, 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 and proximal cauline narrowing abruptly to elongated petioles, blades spatulate to lanceolate or ovate, 60–120(–150) × 14–45(–65) mm, gradually reduced distally, margins serrate (teeth 4–17), abaxial faces glabrous, glabrous or hairy along nerves, adaxial glabrous or sparsely strigose;

mid to distal cauline petiolate to sessile, abruptly to gradually tapering to short broadly winged petiole-like bases, blades lanceolate, 22–46(–57) × 8–20(–29) mm, bases rounded, margins entire to slightly serrate, apices acute to acuminate, faces glabrous or sparsely hairy.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

5–25 mm, densely short hispido-strigose;

bracteoles 0–3, linear.

campanulate, 4.5–5.5 mm.

campanulate, (8.6–)9.5–11.5(–12.5) mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

7–13;

laminae (4–)4.5–6.5 × 1–2 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

14–29;

corollas (4.4–)5–6 mm;

lobes 1–2 mm.

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

in 2–3 series, sometimes weakly unequal, glabrate, margins ciliate;

outermost ovate, 3–5(–7) mm, acuminate, innermost lanceolate, 1-nerved, tapering to rounded tip.

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.

2–110+ (1–10 per branch) in leafy, racemiform or short, axillary and terminal racemiform-paniculiform clusters, lateral branches erect, 4–43 cm.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(± linear-obconic) 1.4–4.4 mm, glabrous;

pappi (3.7–)5–6.5(–7.3) mm.
