Flora of North America species comparison

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

1–20(–50+), stout, finely puberulent or scabrous-puberulent at least distally.

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.

basal absent at flowering;

cauline sessile to short-petiolate;

blades usually lanceolate-elliptic or ovate, sometimes linear-lanceolate, 30–150 × 5–30 mm, thick and firm, margins entire or few toothed, somewhat to much reduced distally, abaxial faces sometimes resinous and shiny, glabrous or strigillose (hairs mostly 0.1–1.4 mm), adaxial glabrous or scabrous.

0.5–5 mm, moderately to densely strigose;

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

mostly 2–15 mm, bracteolate, sparsely to densely short hispid-strigose.

campanulate, 4.5–7(–8) mm.

campanulate, 4.5–7.5 mm.

1–5;

laminae (2–)2.5–4(–5) × 0.7–2 mm.

(5–)7–9;

laminae 3–7 × 1–2 mm.

4–8(–11);

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

(8–)10–16;

corollas 4–5 mm, lobes ca. 1–2 mm.

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.

in 3–4 series, unequal, linear-lanceolate, acute to attenuate, ± squarrose-tipped, glabrous or moderately strigose, sparsely to moderately stipitate-glandular, sometimes viscid.

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

10–190+ in paniculiform (rarely racemiform) arrays, usually elongate, usually leafy-bracteate, bracts similar to distal leaves but reduced;

branches stiffly ascending, not secund, sometimes elongate.

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

pappi 3–4.5 mm.

3–4 mm, glabrous or glabrate;

pappi ca. 4 mm.
