Flora of North America species comparison

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

1(–3), ascending to erect, velutinous or loosely hirsutulous.

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 petioles winged (narrowly so in proximalmost), to 10 cm, bases flared, auriculate-clasping (at least in proximalmost), blades broadly ovate, 35–120 × 30–70 mm, bases cordate, margins serrate, adaxial faces glabrate or sparsely finely scabrous or finely strigose, abaxial pilose on nerves;

mid cauline similar to proximal, petioles shorter, broadly winged, strongly auriculate-clasping;

distal sessile, blades ovate, 20–40 × 10–20 mm, bases winged, narrowed, auriculate-clasping, becoming ovate and cordate-clasping in arrays, reduced to 10 mm.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

1–3 mm;

bracteoles linear-lanceolate, minute, grading into phyllaries.

campanulate, 4.5–5.5 mm.

campanulate, 3–4(–5) mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

1–3;

laminae 1–2 × 0.5–0.75 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

4–8;

corollas 3–3.5 mm, lobes ca. 1 mm.

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

in 2–3 series, lanceolate, strongly unequal, acute to attenuate, 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, secund, in paniculiform arrays, branches relatively few, short to elongated and arching.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

2–2.5 mm, distinctly ribbed, short-strigose;

pappi ca. 2 mm (bristles in 2 weak series, shorter than cypsela bodies, inner weakly clavate).
