Flora of North America species comparison

1–5+, ascending to erect, proximally glabrous, distally usually glabrous or sparsely puberulent, rarely densely hirsute.

5–10+, erect or arching (light to dark brown), proximally sparsely to moderately finely woolly-pilose (hairs spreading to ascending), more densely so distally.

thin, margins entire or often serrate, apices acute, faces glabrous or sparsely puberulent;

basal withering by flowering, petiolate to subpetiolate, blades oblanceolate to narrowly elliptic or linear, 50–150 × 3–25 mm, bases attenuate, margins entire or sometimes serrate, apices acute;

proximalmost cauline withering by flowering, subpetiolate or sessile, blades obovate or oblanceolate to narrowly elliptic, rarely linear, 50–150 × 4–35 mm, bases attenuate or cuneate;

distal sessile, blades 30–100(–130) × 3–15(–30) mm, bases cuneate, rounded or sometimes ± auriculate, margins sometimes serrate, scabrous.

(grayish) soft;

basal withering by flowering, sessile, blades (1–3-nerved) elliptic-lanceolate, 20–40 × 10–20 mm, bases attenuate, margins usually entire, rarely remotely serrate, piloso-ciliate, apices acute to obtuse, faces silvery piloso-silky;

proximal cauline withering by flowering, sessile, blades oblanceolate, 20–30 × 4–8 mm, bases rounded, subclasping, margins entire, scabrous to silky-piloso-ciliate, apices acute to obtuse, cuspidate-mucronate, faces moderately strigillose;

distal sessile, blades lanceolate to narrowly ovate, 8–15 × 2.5–5 mm, reduced distally, bases cuneate, margins entire, apices acute, mucronate, faces moderately, finely lanoso-strigose.

sparsely hairy, bracts 1–10, lance-oblong to linear, sometimes clasping, margins scabrous.

densely hairy, bracts linear, grading into phyllaries.

campanulate, 5–8(–10) mm.

in 4–6 series, appressed or squarrose, oblong or narrowly oblanceolate or linear (outer) to linear (inner), unequal to subequal (outer shorter than or equal to inner, often less than 3 times as long as wide), bases outer indurate less than 1/2 (some foliaceous), inner scarious, margins entire, sometimes ciliate, green zones obovate to elliptic, apices acute to obtuse, faces usually glabrous, rarely sparsely puberulent.
