Flora of North America species comparison

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

1, erect, slender.

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 tufted, tapering, petiolate, petioles 20–100 mm, blades oblanceolate or elliptic, 30–120 (including petiole) × 5–15 mm, obtuse to rounded;

cauline sessile, blades oblanceolate to linear-lanceolate, 5–80 × 4–1.3 mm, abruptly reduced proximally, becoming bractlike proximal to arrays.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

2–25 mm;

bracteoles crowded, linear, 1–2 mm, grading into phyllaries.

campanulate, 4.5–5.5 mm.

broadly campanulate, 3.5–5 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

6–14;

laminae 2–3 × 1–2 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

mostly 12–30;

corollas 3.5–4 mm, lobes 0.5–0.75 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, acute to slightly acuminate or cuspidate, 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.

5–20(–50), in slender racemiform or paniculiform arrays, sometimes secund and apically recurved, more often erect and not secund, sometimes compact and somewhat rounded to only slightly elongate.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

1.5–2 mm, sparsely finely strigose;

pappi (basally broader and flattened, fused to varying lengths) 3–4 mm (somewhat clavate).
