Flora of North America species comparison

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

1 or in clones 2–5+, proximally glabrous or short-strigose in arrays.

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 and proximal cauline tapering to long, winged petioles (to 100 mm), blades elliptic to obovate or ovate, 80–200 (including petioles) × 25–80 mm, bases broadly to narrowly attenuate, margins serrate, apices acute or obtuse, faces glabrous or sparsely scabroso-strigose;

mid to distal cauline sessile, blades linear-elliptic to elliptic-oblanceolate, 20–60 × 4–20 mm, much reduced distally and usually ascending to appressed, bases tapered, margins entire to sparsely shallowly serrate, ciliate, apices acute.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

1–4 mm short-strigose, bracteolate.

campanulate, 4.5–5.5 mm.

campanulate, 4–5(–5.8) mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

4–6;

laminae ± 2 × 1 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

5–7;

corollas 4–5 mm, lobes 1–1.5 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, ascending, lanceolate to oblong, strongly unequal, margins finely fimbriate-ciliate distally, midnerves swollen apically, apices broadly acute to obtuse, faces 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.

50–140, secund on longer branches, less so on apical branches, in open paniculiform arrays, proximal branches ascending and bracteate, apical portions arching.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(greenish turning golden brown, obconic) 2–3 mm (ribs 4–7), short strigose, more so on distal 1/2;

pappi 3–4 mm.
