Flora of North America species comparison

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

1(–5), erect, usually branching only in array, moderately to densely hispido-villous.

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 tapering to winged petioles, blades oblanceolate to ovate, 35–210 × 15–50 mm, margins serrate or crenate, apices acute, sparsely to moderately soft hispido-villous, more densely so on abaxial nerves;

rosettes on rhizome branches sometimes present at flowering;

mid and distal cauline sessile, blades elliptic, 15–50 × 5–15 mm, distally reduced, margins entire.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

1.5–2.5 mm, hispido-villous to canescent.

campanulate, 4.5–5.5 mm.

campanulate, 3–5 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

7–9 (white);

laminae 3.5–4 × 1–1.5 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

9–12;

corollas 3–4 mm, lobes 0.6–1.2 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, oblong, margins white, scarious, apices obtuse to rounded.

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.

12–270 (1–15 per branch) in usually wand-shaped paniculiform arrays, of short axillary and terminal racemiform, non-secund clusters, sometimes proximal branches elongated, ascending and bearing short axillary and terminal racemiform clusters.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(narrowly obconic) 1.5–2.5 mm, smooth or with 5–8 narrow, darker, sunken striations, glabrous or sparsely strigose;

pappi 2.5–3.5 mm (sometimes strongly clavate).
