Flora of North America species comparison

1–5, sparsely to moderately strigoso-puberulent.

1–20+, erect, glabrate proximally or sparsely strigoso-villous, becoming more densely so distal to mid stem.

basal petioles 3–5 cm, blades oblanceolate or spatulate to ovate or rotund, 2–4 cm (excluding petioles);

cauline (numerous) subsessile or sessile, blades elliptic or lance-elliptic to ovate, mid mostly 25–50(–65) × 10–25 mm, distal much reduced;

branch leaf petioles 1 mm, blades ovate, 5–15 (excluding petioles) × 2–10 mm.

basal 0;

proximal to mid cauline usually withering by flowering, tapering to sessile bases, blades narrowly ovate-lanceolate, 50–190 × 5–30 mm, margins sharply serrate, 3-nerved, apices acuminate, abaxial faces glabrous or more commonly hairy along main nerves, adaxial glabrous or slightly scabrous;

mid to distal similar, 30–50(–120) × 8–12 mm, largest near mid stem, reduced distally, margins usually serrate or serrulate (teeth 3–8), sometimes entire proximal to arrays.

linear, 1–3 mm, bracteate.

3–3.4 mm, bracteoles 0–3, linear-triangular.

narrowly campanulate, 3–5 mm.

narrowly campanulate, 1.7–2.5(–3) mm.

0(–2).

(2–)3–6(–8);

corollas 2.2–2.8(–3) mm, lobes 0.4–0.8(–1) mm.

in 3–4 series, lanceolate, strongly unequal, margins ciliate, apices acute, glabrous.

in 3–4 series, strongly unequal, acute to obtuse;

outer lanceolate, inner linear-lanceolate.

75–200 in open paniculiform arrays, branches divaricate, ascending to recurved, weakly to strongly secund, to 50 cm, secondary branches less than 3 cm.

(70–)150–1300+, secund, in secund pyramidal-paniculiform arrays (obscurely so and club-shaped thyrsiform in small plants or shoots with small arrays), branches divergent and recurved, branches and peduncles hairy.

2.5–3 mm, moderately short-strigose;

pappi 2 mm.

(narrowly obconic) 1–1.5 mm (ribbed), sparsely strigose;

pappi 1.8–2.2 mm.
