Flora of North America species comparison

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

1–5+, flexuous, sparsely to moderately hairy in 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.

rosettes present at flowering;

basal and proximal cauline tapering to winged petioles, blades ovate, (70–)100–140(–180) × (27–)40–60(–80) mm (petioles 1/4–1/2 total leaf length), margins serrate-serrulate [teeth (14–)21–33(–45)], abaxial faces glabrous or moderately hairy, more densely so on nerves, adaxial glabrous or sparsely hairy;

mid to distal cauline sessile, blades narrowly ovate to lanceolate, 38–90(–150) × 10–30(–55) mm, reduced distally, becoming lanceolate in arrays, bases tapering, margins entire to serrate, apices acuminate to cuspidate, faces glabrous or sparsely hairy, abaxial glabrous or moderately hairy, more densely so along nerves.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

0.5–5 mm, moderately to densely strigose;

bracteoles 1–3, lanceolate, usually near base of involucres and grading into phyllaries.

campanulate, 4.5–5.5 mm.

campanulate, 4.5–7(–8) mm.

6–8;

laminae 3–4 × 1–1.5 mm wide.

1–5;

laminae (2–)2.5–4(–5) × 0.7–2 mm.

8–14;

corollas 4–5 mm, lobes ca. 1.5 mm.

4–8(–11);

corollas 2–3(–4) mm, lobes 1–1.6(–2) mm.

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

in ca. 3 series, strongly unequal, outermost 1–2 mm, innermost 3.7–4.7(–5.7) mm, linear-oblong, 1-nerved, apices obtuse to acute.

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.

25–250, in short axillary and terminal racemiform clusters, lateral panicles (2–)7–31(–56) cm.

(reddish brown) 2–3 mm, glabrous;

pappi 4–5 mm.

(obconic) 1–2(–3) mm, moderately to densely strigose;

pappi 3–4.5 mm.
