Flora of North America species comparison

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

1, ascending-erect, softly short villous.

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 winged-petiolate petioles (petioles 1/2+ leaf length), blades broadly ovate (or subcordate) to elliptic, 50–100(–160) × 30–40 mm, margins shallowly serrate-crenate, apices acute to obtuse, soft short-villous;

mid and distal cauline subpetiolate or sessile, blades ovate to elliptic, 20–40 × 5–15 mm, greatly reduced, becoming narrowly elliptic.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

slender.

campanulate, 4.5–5.5 mm.

campanulate, 4–5 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

usually 7–12;

laminae 3–6 × 1.5–2 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

usually 14–27;

corolla tubes 4 mm, lobes 0.8–1 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, broadly lanceolate, unequal, glabrate or sparsely short-strigose.

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.

50–100, in paniculiform arrays, proximal branches obscurely to evidently recurved-secund.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

1.5–2.5, sparsely strigose;

pappi ± 3 mm (shorter than corollas).
