Flora of North America species comparison

1–20+, erect, proximally sparsely to moderately strigoso-villous, distally usually moderately to densely so.

1, erect, slender.

basal 0;

proximal cauline sessile, blades narrowly to broadly oblanceolate, 35–75(–100) × (6–)7.5–14(–20) mm, proximal much smaller, tapering to bases, margins subentire or finely serrulate to coarsely, sharply serrate (teeth 0–9 per side), ciliate, 3-nerved, sometimes obscurely so, apices acute, abaxial faces glabrate to sparsely short-strigose, adaxial glabrous;

mid to distal cauline sessile, blades oblanceolate, becoming lanceolate distally, 20–60 × 4–8(–11) mm, largest near mid stem, somewhat to much reduced distally, margins entire or finely serrulate, rarely serrate (teeth 1–8 per side), usually becoming entire to sparsely serrulate distally, ciliate, apices acute, faces glabrous or sparsely strigoso-villous, more so along abaxial 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.

2–7 mm, sparsely to moderately short strigoso-villous;

bracteoles 1–3, linear, rarely minutely stipitate-glandular.

2–25 mm;

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

narrowly campanulate, 2.5–3.5(–4) mm.

broadly campanulate, 3.5–5 mm.

(8–)11–15(–17);

laminae 1–2.5 × 0.1–0.4(–0.7) mm.

6–14;

laminae 2–3 × 1–2 mm.

(3–)5–11(–16);

corollas 2.6–3.7(–4) mm, lobes 0.5–1.2 mm.

mostly 12–30;

corollas 3.5–4 mm, lobes 0.5–0.75 mm.

in 3–4 series, strongly unequal, margins sparsely long ciliate, acute, faces glabrous, rarely sparsely minutely stipitate-glandular;

outer lanceolate, inner linear-lanceolate.

in 3–4 series, linear-lanceolate, strongly unequal, acute to slightly acuminate or cuspidate, glabrous.

12–500+, sometimes secund, in short to long, thyrsiform or narrowly secund-pyramidal paniculiform arrays, usually congested, club-shaped to rarely wand-shaped, (2.5–) 10–20 × (2–)4–8(–10) cm, branches usually ascending or sometimes arching spreading.

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.

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

pappi 2.5–3.3 mm.

1.5–2 mm, sparsely finely strigose;

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