Flora of North America species comparison

1–5+, ascending to erect (often with purple or purplish brown areas, flexuous, wiry), little-branched, usually glabrous, sometimes hairy in lines distally.

1–3+, decumbent to ascending (curved or straight, sometimes stout, green to reddish brown), glabrous.

thick (fleshy), margins entire, faces glabrous;

basal withering by flowering (new winter rosettes appearing at flowering), petiolate (petioles sheathing), blades ovate or oblanceolate, 15–20 × 5–15 mm, bases cuneate, apices rounded;

proximal cauline withering by flowering, usually sessile, blades lanceolate, linear-lanceolate or -oblanceolate, to linear, 7–80(–150) × 1–6 (–12) mm, bases attenuate, margins entire, apices acuminate to acute;

distal sessile, blades narrowly lanceolate to subulate, 10–110 × 0.5–5 mm, apices acuminate.

(dark green to bluish green) thin, apices acute to acuminate, mucronate, faces glabrate or glabrous;

basal withering by flowering (vernal rosettes developed at flowering), petiolate or sessile (petioles winged, sheathing, ciliate), blades oblanceolate to obovate, 10–70 × 3–5 mm, bases cuneate to attenuate, margins entire or rarely sparsely serrate distally, apices obtuse to rounded, cuspidate;

proximal cauline usually withering by flowering, petiolate or sessile (petioles narrowly winged, bases ± clasping), blades oblanceolate to linear-oblanceolate, 70–105 × 2–4 cm, bases attenuate to cuneate, or ± auriculate, ± clasping;

distal sessile, blades linear-lanceolate to narrowly subulate, 5–65 × 1–4 mm, progressively reduced distally, bases subauriculate, ± clasping, margins entire, with marginal cilia proximally, faces glabrous; reduced array leaves often in fascicles along branches, markedly 3-nerved.

0.6–4 (–6) cm, bracts 2–8, awl-shaped, grading into phyllaries.

0.4–2 cm, mostly borne on secondary branches, glabrous, bracts 3–6, linear to subulate, stiff, distalmost sometimes surpassing involucres, glabrous.

narrowly turbinate, 4.1–9.5(–11) mm.

cylindric, (4.5–)5.5–7.1(–8.5) mm.

10–25;

corollas white or pink, laminae (4.5–)5–8.5(–9.5) × 1.2–2 mm.

(13–)20–28(–34);

corollas usually blue-violet, rarely white, laminae (7–)9–15(–19) × 0.6–2.1 mm.

25–45(–54);

corollas yellow becoming purplish, 3.4–6(–6.8) mm, tubes shorter than to equaling the narrowly funnelform throats (sparsely hairy at base), lobes ± erect, narrowly triangular, 0.5–0.8 mm.

(28–)33–51(–68);

corollas yellow turning brown, 3.4–4.6(–5.5) mm, tubes shorter than funnelform throats, lobes lanceolate, 0.5–1 mm.

in 4–5 series, lanceolate to subulate, bases indurate, rounded, margins hyaline, often tinged with purple, entire, green zones spatulate to oblanceolate-rhombic, apices acute, adaxial faces glabrous or minutely hairy distally.

in 4–6 series, oblong-lanceolate to -oblanceolate to sometimes linear (innermost), unequal to subequal, bases indurate 1/4–2/3, margins narrowly scarious, erose, hyaline, sometimes sparsely ciliolate, green zones diamond-shaped to lanceolate, apices acute to long-acuminate, involute, spreading, mucronate to apiculate, faces glabrous.

(1–)3–20(–40), in open, diffuse, paniculiform arrays, branches patent.

in leafy, paniculiform to racemiform arrays, branches nearly divaricate to ascending, straight, sometimes secund, secondarily ramified, leafy with array leaves ± stiff, asscending to appressed.

light brown, narrowly obovoid to fusiform, sometimes ± compressed, 1.5–4(–4.5) mm, 5–6-nerved, faces sparsely strigillose;

pappi tawny to white, 3–6.1 mm.

tan to brown, obovoid, ± compressed, 1.5–2.1 mm, 4–5-nerved (thin), faces sparsely strigillose;

pappi white, 3–5 mm.
