Flora of North America species comparison

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

1, erect, glabrous proximal to (and usually into proximal portions of) 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 present at flowering, abruptly tapering to winged petioles, blades ovate, 100–200 × 80–120 mm, broadly tapering to truncate or slightly cordate (rarely) bases, margins singly or doubly serrate (teeth 1–3(–6) mm);

mid to distal cauline subsessile to sessile, blades lanceolate, 130–200 × 45–85 mm, progressively reduced distally, margins serrate (teeth 1–3 mm), abaxially glabrous, adaxially scabrous-hispidulous at least along margins.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

2–5 mm (4–13 mm on South Carolina plants).

campanulate, 4.5–5.5 mm.

campanulate, 4.5–6(–7) mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

4–6;

laminae 2.2–3.5 × 0.8–1.7 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

5–7(–11);

corollas 4–5.6 mm, lobes 1.6–2.5 mm.

in ca. 3 series, strongly unequal, erect to slightly squarrose-tipped, lanceolate, apices acute, glabrate, sparsely to moderately, finely stipitate-glandular.

(10–18) in 4–6 series, ascending, lanceolate, broadly acute to obtuse, glabrous except for fimbriate-ciliate margins towards tip.

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.

40–70, inconspicuously secund on longer branches, appearing fasciculate on shorter branches, borne in variable arrays, mostly narrow elongate and secund, consisting of axillary and terminal racemiform branches, or wider and compound, consisting of multiple array branches, proximally leafy-bracted, branches and peduncles (2.5–)4(–13) cm, hairy.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

2.5–3.2 mm, short hairy at least on distal half;

pappi 3–4.7 mm.
