Flora of North America species comparison

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

1–5+, glabrous, sparsely strigose in arrays.

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 petiolate;

blades broadly elliptic to ovate, 100–350 × 60–120 mm (including petioles), bases truncate to obtuse, apices acute to acuminate, margins sharply serrate, glabrous;

distal cauline blades spreading to ascending, linear-elliptic, 30–50 × 6–15 mm.

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

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

1.5–3 mm, glabrate to moderately short hispido-strigose, bracteoles 1–5, linear-lanceolate grading into phyllaries.

narrowly campanulate, 2.5–3.5(–4) mm.

campanulate, (4.5–)5–7 mm (much exceeded by pappi).

(8–)11–15(–17);

laminae 1–2.5 × 0.1–0.4(–0.7) mm.

4–9;

laminae 4–5 × 1.5–2.5 mm.

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

9–11;

corollas 4–5 mm, lobes ca. 1.5 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.

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.

25–50+, in elongate, paniculiform arrays, proximal branches recurved-secund, sometimes elongate.

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

pappi 2.5–3.3 mm.

(brown, ribs dark brown) 3 mm, sparsely short-strigose;

pappi 3–4 mm.
