Flora of North America species comparison

1, erect (often with purple or purplish brown areas), glabrous or glabrate, sometimes strigillose in leaf axils.

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

thin (green to dark green), margins often strigilloso-ciliolate, faces glabrous;

basal withering by flowering, long-petiolate (petiole bases sheathing), sparsely ciliate, blades ovate to oblanceolate, 10–90 × 6–14 mm, bases attenuate to cuneate, rounded, margins entire or serrulate or crenulate, apices rounded, obtuse, or acute;

proximal cauline withering by flowering, petiolate, subpetiolate, or sessile, blades narrowly lanceolate or subulate, 20–100(–200) × 1.5–10(–20) mm, bases attenuate, margins subentire, entire, or serrulate, apices acute to acuminate;

distal sessile, blades narrowly lanceolate to subulate, 5–113 × 0.5–5.5 mm, apices acuminate.

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.

(0.2–)0.5–4 cm, bracts 4–8(–17).

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

cylindric to turbinate, 5–7(–8.2) mm.

narrowly campanulate, 8–11 mm.

16–30(–54) in 1–3 series;

corollas white, pink, or lavender, laminae 1.3–7 × 0.2–1.3 mm.

(25–)30–46+;

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

4–10(–13);

corollas yello, sometimes tinged with purple, 3.4–5.2 mm, throats narrowly funnelform, lobes ± spreading to erect, narrowly triangular, 0.3–0.7 mm, glabrous.

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 3–5 series, broadly or narrowly lanceolate to subulate, unequal, bases indurate, margins hyaline, often purple-tinged, entire, green zones lanceolate (usually narrow, sometimes broad and covering most of distal portion), apices acute, faces glabrous.

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.

(10–) 30–100(–150), in open, diffuse, paniculiform arrays.

in paniculiform arrays, branches strongly ascending, leafy.

light brown to purple, narrowly obovoid to fusiform, sometimes ± compressed, (1.2–)1.5–2.7(–3) mm, 5-nerved, faces sparsely strigillose;

pappi white, (3–)3.5–5.5 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.
