Flora of North America species comparison

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

1–5+, erect, glabrous or branches of arrays puberulent.

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 withering by flowering;

mid and distal cauline numerous (to 50+ on taller stems), sessile or nearly so (bases of blades sometimes subauriculate and rounded to short petioles), blades elliptic or lanceolate-elliptic, larger 60–150 × 15–35 mm, little reduced distally, margins serrate to entire, not 3-nerved, obscurely to obviously reticulately nerved, faces barely rugose, glabrous.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

4–10 mm, sparsely to moderately strigose;

bracteoles 1–3+, linear-lanceolate, usually a few near head grading into phyllaries.

campanulate, 4.5–5.5 mm.

campanulate, 4–6 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

6–10;

laminae 2–3 × 0.8–1.3 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

4–7;

corollas 3–4 mm, lobes 0.9–1.3 mm.

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

in 4–5 series, strongly unequal, margins apically ciliate, obtuse to rounded, glabrous;

outer ovate-lanceolate, inner linear-lanceolate, relatively broad, 0.7–1.2 mm.

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.

35–800, in paniculiform arrays, sometimes leafy-bracteate, with short or elongate, slightly to strongly recurved, secund branches.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(obconic) 1.5 mm, sparsely strigose;

pappi 3.5–5 mm.
