Flora of North America species comparison

1–20+, ascending to erect (sometimes ± brittle, green to light-green proximally, greenish to whisith distally), moderately to densely hispid and short-strigose, abundantly long-hispid, sometimes becoming moderately hairy and densely stipitate-glandular distally.

proximal cauline petiolate to subsessile, blades (whitish when fresh, drying grayish to whitish green) narrowly to broadly oblanceolate, 15–45 × 5–8 mm, bases attenuate, margins flat, entire, strigoso-ciliate, proximally long-hispido-strigose, apices acute, faces densely hispido-strigose, sparsely to moderately stipitate-glandular;

distal sessile, blades narrowly to broadly ovate or lanceolate to oblong, 10–20(–30) × 2.5–7.3 mm, reduced distally, densely to very densely hispido-strigose, moderately to densely stipitate-glandular beneath hairs.

9–41 mm, moderately to densely hispido-strigose, moderately to densely stipitate-glandular;

bracts 0–5, proximal lanceolate, much reduced distally;

linear to oblanceolate, leaflilke bracts sometimes subtending heads.

cylindro-turbinate to narrowly campanulate, (4.3–)5–7.5(–8) mm.

8–18(–23);

laminae 6.5–13 × 1–1.7 mm.

(11–)16–44(–62);

corollas ± ampliate, (3.5–)4.5–7 mm, lobes 0.4–0.7 mm, sparsely pilose (hairs on lobes 0.1–0.3 mm).

in 5–6 series, lanceolate, unequal (outer lengths 1/5–1/4 inner), margins scarious, faces either sparsely hispido-strigose and densely stipitate-glandular or moderately hispido-strigose and sparsely to moderately stipitate-glandular.

7–27(–46) in corymbiform arrays, branches ascending.

monomorphic, obconic, compressed, 1.5–3(–4) mm, ribs ca. 10, faces moderately strigose;

pappi off-white, outer of linear scales 0.25–0.5 mm, inner of 25–40 weakly clavate bristles 4–7 mm.
