Flora of North America species comparison

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

1–20, erect, finely scabroso-puberulent, sparsely so with age proximally, densely so distally.

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, subsessile, gradually tapering to short-winged petiole-like bases;

mid and distal cauline sessile, blades linear-elliptic to linear-lanceolate, 40–90 × 4–5 mm, 3-nerved from base, midnerves prominent, margins entire, finely scabrous, apices attenuate-acute, faces finely, sparsely to moderately strigose, more so on main nerves, finer nerves translucent, faces sometimes shiny.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

2–6 mm, finely strigose;

bracteoles 1–10, often crowded, linear-lanceolate, 2–3 mm, grading into phyllaries.

campanulate, 4.5–5.5 mm.

narrowly campanulate, 3.5–4 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

4–5;

laminae 1.5–2.5 × 0.5 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

6–8, 3–3.5 mm, lobes 0.5 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, linear-lanceolate, strongly unequal, margins hyaline, distally subulate-ciliate, apices 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.

25–350, in short to elongate, secund paniculiform arrays, branches ascending or ascending and distally recurved, sometimes second, sometimes elongate.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(narrowly obconic) 1.5–2.5 mm, sparsely strigillose;

pappi 3 mm.
