Flora of North America species comparison

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

single (sometimes purplish brown, ridged), glabrous, strigose distally 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 tapering to winged petioles, blades (basal) spatulate, 20–40 mm, (proximal) obovate to oblanceolate or elliptic, 60–150(–200) × 30–55 mm, margins serrate (teeth shallow to 5 mm), ciliate, acute to obtuse, acuminate or mucronate, faces abaxially glabrate to sparsely strigose, especially on nerves, adaxially glabrous;

mid and distal cauline sessile, lancelate or oblanceolate to elliptic, 30–100 × 20–40 mm, reduced distally, margins serrate to entire distally.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

1–3 mm, strigose;

bracts and bracteoles lanceolate to ovate, grading into phyllaries.

campanulate, 4.5–5.5 mm.

campanulate, ca. 5 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

ca. 6–10;

laminae 1.5–2.5 × 0.5 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

ca. 10;

corollas 3.5–5 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, appressed, strongly unequal, outer grading from ovate bracteoles, mid oblong, rounded, inner linear-oblong, acute, 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.

20–180+ (1–6 per branch), in leafy wand-paniculiform arrays (2–)10–20(–40) cm, lateral branches usually not exceeding subtending leaf bracts.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(narrowly obconic) 2.5–3 mm, moderately strigillose;

pappi ca. 4 mm (sometimes weakly clavate).
