Flora of North America species comparison

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

1–5+, erect, straight (stout, brittle), glabrous or sparsely hirtellous in lines.

(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.

(paler green or bluish green abaxially) firm, margins scabrous, apices mucronate, faces glabrous, abaxial raised midribs scabrous to glabrate;

basal withering by flowering, subpetiolate to shortly petiolate (petioles winged, sheathing, coarsely ciliate), blades oblanceolate to oblong-oblanceolate, 45–65 × 5–8 mm, bases cuneate, margins shallowly crenate, strigoso-ciliate, apices acute, obtuse or rounded;

proximal cauline withering by flowering, subpetiolate or sessile, blades elliptic-lanceolate to linear-oblanceolate or -lanceolate, 40–120 × 5–20 mm, reduced distally, bases cuneate to slightly attenuate or rounded, slightly clasping, margins serrulate-crenate or entire, apices acute to acuminate;

distal sessile, blades oblanceolate or elliptic-lanceolate to linear-lanceolate or linear-oblong, (10–)15–100 × 1–5 mm, gradually reduced distally (more strongly so on branches), bases cuneate or rounded, margins entire, apices acuminate.

densely hairy, bracts linear, grading into phyllaries.

long, thin, (1–)4–10(–25) cm, branches to 10 cm, bracts 8–15, regularly spaced but becoming crowded distally, appressed or ascending, linear-oblong to subulate, 1.5–4 mm, grading into phyllaries, mucronulate.

campanulate, 7–9 mm.

turbinate to cylindro-campanulate, 7–12 mm.

7–12;

corollas rose-purple, laminae 6–9 × 1–2 mm.

14–20;

corollas light blue to lavender or purple, laminae 12–20 × (1–)1.5–2.8 mm.

14–20;

corollas pink turning purple, 5–6 mm, tubes shorter than narrowly funnelform throats (thinly puberulent), lobes triangular, 0.3–0.5 mm.

15–20+;

corollas yellow turning purple, (4.5–)5–7 mm, tubes slightly shorter than narrowly funnelform throats, lobes triangular, 0.5–1 mm.

in 3–4 series, spreading to reflexed, linear, unequal, bases (tan) ± indurate, margins scarious proximally, green distally, green zones foliaceous, apices acute, faces moderately woolly-strigose.

in 6–9 series, appressed or ± spreading, shortly oblong-lanceolate to subulate (outer) to linear-oblong or linear (inner), strongly unequal, bases indurate 1/2–5/6, abaxially rounded, margins scarious, erose, hyaline, sparsely ciliolate distally, green zones oblanceolate to rhombic-oblanceolate, in distal 1/6–1/2, apices acute (outer) to obtuse or rounded (inner), often callous-mucronulate, faces glabrous.

radiate, in narrow, paniculiform (wand-shaped) to sometimes compact, racemiform arrays (1(–3) per branch).

in open, broad, much ramified, paniculiform arrays, branches ascending to arching, thin, brittle, remotely leafy, rarely sessile.

fusiform-obovoid, not compressed, 2–3 mm, 6–8-nerved, faces densely strigose;

pappi tan to yellowish tan, (5.5–)6.5–8 mm.

yellow-tan or light brown to gray, obovoid, ± compressed, (1.8–)2–2.8 mm, 2–4-nerved, faces minutely strigillose;

pappi whitish to reddish brown, 4.5–6.4 mm.
