Flora of North America species comparison

1, erect to arching, light to dark brown, soft-hairy, hairs ascending- to spreading- stipitate-glandular distally.

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

(dark green) thin, almost membraneous;

basal early deciduous, sessile or subpetiolate, blades spatulate to obovate, 80–140 × 20–30 mm, bases cuneate, margins entire to ± serrate, scabrous, apices acute;

proximal cauline withering by flowering, sessile, blades panduriform, (20–)30–70(–110) × 10–30(–35) mm, bases auriculate-clasping, margins entire (flat), sparsely villoso-ciliate, apices acute, faces finely sparely villous or scabrous, stipitate-glandular;

distal sessile, blades (rugose-veined when fresh) ovate to lanceolate, 75–125(–140) × 15–35(–40) mm, bases strongly cordate-clasping to auriculate-amplexicaul, margins entire (± undulate), apices acute, acuminate to merely mucronate, faces sparsely strigose, moderately so along veins, sparsely to moderately stipitate-glandular.

(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.

short (less than 4 cm), strigose, stipitate-glandular, bracts linear-lanceolate, ascending-appressed, grading into phyllaries.

densely hairy, bracts linear, grading into phyllaries.

cylindric, 5.5–7.5(–8) mm.

campanulate, 7–9 mm.

9–17;

corollas light to dark reddish purple, laminae 10–18(–20) × 1–3 mm.

7–12;

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

15–35;

corollas white with purple lobes, 6–8 mm, lobes triangular, 1–1.5 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.

in 4–6 series, linear-lanceolate, unequal, bases (tan) ± indurate in proximal 1/3–1/2, margins hyaline, erose, distally scabro-ciliolate to ciliolate, green zones covering distal 1/2, apices outer obtuse to acute, inner acuminate, purplish, faces sparsely strigillose, usually moderately to densely stipitate-glandular, rarely sparsely so.

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 crowded, paniculiform arrays, branches often initially patent then ascending.

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

dark brown to black, obovoid, not compressed, 2.5–4 mm, 7–10-nerved, faces densely strigose along ribs;

pappi tan to tawny, sometimes slightly purplish-tinged, 6–8 mm.

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

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