Flora of North America species comparison

1, erect (± flexuous, often reddish), glabrous, hairy in lines distally.

1, erect (straight, stout, sometimes purplish pink), mostly glabrous, hirsutulous in arrays, mainly in lines.

stiff, margins sparsely serrulate or entire, ± revolute, scabrous, apices acute to acuminate, mucronulate, faces glabrous, sometimes midveins hairy;

basal withering by flowering, long-petiolate, petioles narrowly winged, bases sheathing, blades lanceolate, ca. 20 × 3–5 mm, slightly attenuate to narrowly cuneate;

proximal cauline withering by flowering, sessile or subpetiolate, blades linear-lanceolate to -oblanceolate, 100–200 × 4–8 mm, bases cuneate to attenuate, clasping;

distal sessile, blades linear-lanceolate to linear, 10–110 × 1–7 mm, progressively reduced distally, bases cuneate to rounded, slightly clasping or not, margins entire.

firm, margins serrate to serrulate, scabridulous, apices acute to shortly acuminate, apiculate to mucronate, abaxial faces glabrous, adaxial scabridulous;

basal withering by flowering, long-petiolate (petioles narrowly winged, sheathing), blades elliptic, 50–250 × 10–50 mm, bases attenuate;

proximal cauline withering by flowering, long-petiolate to subpetiolate (petioles winged, bases expanded, sheathing), blades elliptic to lanceolate or oblanceolate, gradually reduced distally, 70–110 × 15–35 mm, bases attenuate;

distal subpetiolate or sessile, (petioles broadly winged, bases sheathing to clasping), blades elliptic, 10–70 × 1–30 mm, progressively reduced distally, more strongly so on branches, bases attenuate to cuneate, clasping, margins serrulate or entire.

glabrous or ± densely pilose in lines, bracts 1–4, linear, sometimes inrolled distally, clasping, ciliate, distal 1–2 often subtending and surpassing involucres.

0.5–2.5 cm, to erect, hirsute, bracts 3–5, linear, grading into phyllaries.

campanulate, 5–8.5 mm.

narrowly campanulate, 8–11 mm.

20–35;

corollas dark blue-violet, seldom white, laminae 8–13 × 1–1.5 mm.

(25–)30–46+;

corollas pink or sometimes lavender, laminae 7–14 × 0.8–1.6 mm.

(18–)23–40;

corollas yellow, 4–6.5 mm, tubes shorter than funnelform throats, lobes lanceolate, 0.8–1 mm.

25–35+;

corollas pale yellow becoming pink and later brown, 6–6.2 mm, tubes slightly shorter than narrowly funnelform limbs, lobes narrowly triangular to lanceolate, 0.8–1 mm.

in 3–4 series, oblong-lanceolate, subequal, bases indurate 1/3–3/4, margins scarious, erose, hyaline, ciliate proximally, sparsely ciliolate distally, green zones lanceolate to linear, sometimes outer ± foliaceous, apices acuminate to long-acuminate, often foliaceous, mucronate to apiculate, faces glabrous, eglandular.

in 5–6 series, linear-lanceolate or -oblanceolate to linear, slightly unequal, bases indurate 1/3–1/2, margins narrowly scarious, hyaline, sparsely and remotely ciliolate, green zones lanceolate to linear, outer distally foliaceous, sometimes constricted in middle, apices spreading to squarrose, long-acuminate, apiculate, faces glabrous.

in elongate, open, narrow, paniculiform or racemiform arrays, branches ascending, short, leafy, branch leaves smaller and reduced distally (heads 1–3 per branch).

in paniculiform arrays, branches strongly ascending, leafy.

tan, obovoid, compressed, ca. 2.2–2.4 mm, 5–6-nerved, faces sparsely strigillose;

pappi pinkish, 7–8 mm.

tan to pale brown, oblanceoloid, compressed, 2–2.7 mm, 3–4-nerved, faces glabrous or sparsely hairy;

pappi sordid or whitish, 5.5–5.8 mm.
