Flora of North America species comparison

1–6(–10), erect, short-canescent (hairs ascending to appressed).

usually single, erect (proximally medium to dark brown distally lighter, sometimes cyanotic, usually rounded, shallowly many ribbed), sparsely finely hispido-strigose proximally to densely so in arrays.

basal and proximal cauline tapering to long, winged petioles, blades spatulate-ovate to oblanceolate, 20–95 × 7–15 mm, margins crenate to entire, apices acute, faces densely puberulent;

mid and distal cauline (sometimes subtending axillary tufts of lateral branch leaves) sessile, blades linear-oblanceolate, 16–45 × 3–7 mm, reduced distally, margins entire.

rosettes often present at flowering, early leaves smaller;

basal and proximal cauline gradually to abruptly tapering to winged petioles, blades elliptic to ovate-elliptic, 90–210 (including petioles) × 40–70 mm, margins serrate-serrulate, ciliate, apices obtuse to broadly acute, faces abaxially glabrous or sparsely strigose, adaxially glabrous or sparsely strigose, mostly on nerves;

mid to distal cauline sessile, blades lanceolate or elliptic, 20–650 × 10–30 mm, gradually reduced distally, becoming entire, apices acute to acuminate.

2–3.5 mm, bracteoles 0–4, linear.

0.5–11 mm, densely short hispido-strigose;

bracteoles 5–10+, grading into phyllaries, sparsely short hispido-strigose and sparsely to moderately glandular.

narrowly campanulate, 2.6–5.8 mm.

campanulate, 5–8 mm.

5–11;

laminae 2.8–5.5 × 0.3–0.7 mm.

in 3 series, ovate to linear-lanceolate, unequal, outer acute, inner obtuse.

in 4–5 series, appressed, strongly unequal, outer ovate, acute, mid and inner broadly oblong (appressed), obtuse or rounded, sparsely strigose and moderately finely stipitate-glandular.

10–300, secund, in wandlike pyramidal, paniculiform arrays, secund to apically recurved, 8–25 × 2.5–10 cm, sometimes proximal branches elongate, repeating pattern.

50–100+ (1–10 per branch, more on much elongated proximal branches), in elongate to thyrsiform-paniculiform arrays 7–22 × 3–6 cm;

branches ascending, racemiform or paniculiform, not secund, longest to 1/2 length of arrays.

(obconic) 0.5–2 mm, strigose;

pappi 2–4 mm.

(fusiform to obconic) 2.5–3 mm, moderately long-strigose;

pappi 4–6 mm (some clavate).
