Flora of North America species comparison

glabrous or densely piloso-puberulent.

moderately to densely strigoso-hirtellous.

basal and proximal cauline 3–5-nerved, linear to narrowly oblanceolate or oblanceolate, 110–220 × 4–10(–12) mm, gradually then abruptly reduced distally (bractlike proximal to heads), essentially glabrous or sparsely pilose to densely piloso-puberulent, weakly gland-dotted (bases of basal usually fibrous-persistent).

basal and proximal cauline 1-nerved, narrowly oblanceolate to linear-oblanceolate, 90–180 × 2–4(–7) mm, gradually or abruptly reduced distally, essentially glabrous (proximal margins sparsely ciliate).

usually 0, rarely (spreading to ascending) 1–2 mm.

(divergent-ascending, initially diverging at angles of 45–90°) 10–25(–30) mm.

campanulate-cylindric, 7–9(–10) × 3.5–5 mm.

turbinate-campanulate, (5–)6–7.5 × 5–7 mm.

(4–)5–8;

corolla tubes glabrous inside.

7–12;

corolla tubes pilose inside.

(reflexed or curving-spreading) in 4–5 series, oblong-lanceolate, unequal, essentially glabrous or ± pilose, margins with hyaline borders, sometimes ciliate, apices usually acute to acute-acuminate (sometimes distally dilated, nearly petaloid).

in (2–)3–4(–5) series, broadly obovate (outer) to broadly oblong-obovate, strongly unequal, sparsely strigoso-villous (outer) or essentially glabrous, margins with (pinkish purple) hyaline borders, sometimes slightly erose, usually densely ciliate, apices rounded to subtruncate.

in dense, spiciform arrays.

in loose, (columnar) racemiform arrays.

3.8–4.5(–5) mm;

pappi: lengths ± equaling corollas, bristles barbellate.

2.5–2.8 mm;

pappi: lengths equaling or surpassing corollas, bristles barbellate.

globose, sometimes becoming elongate rhizomes.

globose to depressed-globose.
