Flora of North America species comparison

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

usually 1, ascending to erect, uniformly short villoso-strigose, occasionally glabrate proximally.

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 and proximal cauline short-petiolate, blades broadly ovate or elliptic-ovate, margins serrate, ± 3-nerved and pinnately nerved, abaxial faces (at least) evenly short villoso-strigose;

mid and distal cauline like proximal, 20–70 × 10–40 mm (1.3–2 times as long as wide), usually only those near arrays reduced and 1-nerved.

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

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

1–6 mm;

bracteoles ovate, minute, grading into phyllaries.

narrowly campanulate, 2.5–3.5(–4) mm.

campanulate, 3–4.5 mm.

(8–)11–15(–17);

laminae 1–2.5 × 0.1–0.4(–0.7) mm.

3–7;

laminae 1.5–2 × 0.5–1 mm.

(3–)5–11(–16);

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

4–7;

corollas (abruptly ampliate) 3–3.5 mm, lobes ca. 1 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 series, strongly unequal, obtuse or rounded;

mid broadly oblong, inner narrowly so.

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.

30–200+, apparently sometimes drooping, in open leafy, secund pyramidal, paniculiform arrays, branches recurved, leafy-bracteate, secund, proximalmost branch sometimes separated by several nodes from next.

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

pappi 2.5–3.3 mm.

1.5–2 mm (4–8 translucent ribs), moderately short-strigose;

pappi 2–2.5 mm.
