Flora of North America species comparison

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

1–5+, erect, glabrous proximal to 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 cauline tapering quickly to long, winged ciliate-margined petioles, blades ovate, 50–200 × 20–100 mm, margins serrate;

mid to distal cauline sessile, blades oblanceolate, 30–100 × 8–35 mm, reduced distally and becoming lanceolate-ovate, margins entire, abaxially sparsely strigose along nerves.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

8–10 mm.

campanulate, 4.5–5.5 mm.

5–9 mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

corollas 4–5 mm, lobes ca. 1.5 mm.

15–30;

corollas 5–5.6 mm, lobes 0.5–1.2 mm.

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

(20–26) in 4–6 series, recurved, unequal, conspicuously spreading, lanceolate, margins ciliate, apices acute to obtuse, finely strigose.

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.

20–200, not secund, in narrow, elongate arrays of axillary and terminal racemiform clusters, branches and peduncles hairy, leafy-bracteate proximally.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.
