Flora of North America species comparison

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

1–10+, erect, proximally glabrous, increasingly puberulent distally into 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 0;

mid and distal cauline numerous (sometime 100+ per stem), crowded, sessile or subsessile;

blades linear-elliptic, mostly 50–120 × 6–12 mm, tapering at both ends, margins remotely serrulate or subentire, 3-nerved, faces glabrous or sometimes puberulent abaxially on midnerves.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

1–3 mm, sparsely strigose;

bracteoles linear, 1–3.

campanulate, 4.5–5.5 mm.

narrowly campanulate, 2–3 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

mostly 7–11, 1–2 × 0.1–0.2 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

2–7;

corollas 2–3 mm, lobes 0.4–0.6 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, linear-lanceolate, strongly unequal, midribs raised, enlarged apically, apices acute to usually obtuse or rounded, apically ciliate.

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.

80–900+, in paniculiform arrays, branches recurved, secund.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(narrowly obconic) 1–1.5 mm, sparsely strigillose;

pappi 2–2.5 mm.
