Flora of North America species comparison

1–5+, ascending to erect (strict, 0.9–1.7 cm diam., only distal lateral branches developing in larger plants), moderately to densely hispido-strigose, more so proximally, moderately to densely stipitate-glandular, more so distally.

basal and proximal cauline petiolate (petioles 3–7 cm, bases auriculate-clasping), blades ovate or elliptic to oblong, 50–80 × 20–30 mm, margins flat or somewhat undulate, coarsely serrate to serrulate or entire, proximally long-ciliate, apices acute, faces moderately to densely long-hispido-strigose;

distal sessile, blades oblong-lanceolate to lanceolate, 20–40 × 20–30 mm, reduced distally, margins often undulate, coarsely serrate.

10–65 mm, sparsely to densely hispido-strigose, densely stipitate-glandular;

bracts 0–3, linear-lanceolate to linear, reduced distally.

campanulo-hemispheric, 6–9 mm.

20–40;

laminae 5–8 × 1–2 mm.

30–75;

corollas 4–6 mm, lobes 0.5–0.8 mm.

in 4–6 series, linear-lanceolate, unequal, margins scarious, faces strigose, densely stipitate-glandular.

10–110+, in corymbiform arrays, becoming paniculiform with age, branches ascending, usually relatively short compared to plant height.

dimorphic, (ray) 2–5 mm, faces glabrous or slightly strigose on angles, (disc) 4–6 mm, faces moderately to densely strigose;

pappi 0 (ray) or (disc) stramineous to rusty brown, outer bristles 0.4–0.7 mm, inner 6–9 mm, longest weakly clavate.
