Flora of North America species comparison

usually 1, ascending to erect, uniformly short villoso-strigose, occasionally glabrate proximally.

1–10+, erect, proximally glabrous, glabrous or sparsely villoso-strigose in arrays; often with short fascicles in axils of mid to distal cauline leaves.

basal and proximal cauline short-petiolate, blades broadly ovate or elliptic-ovate, margins serrate, ± 3-nerved and pinnately nerved, abaxial faces (at least) evenly short villoso-strigose;

mid and distal cauline like proximal, 20–70 × 10–40 mm (1.3–2 times as long as wide), usually only those near arrays reduced and 1-nerved.

rosettes present at flowering;

basal and proximal tapering to winged petioles, blades oblanceolate, 70–210 × 8–28 mm, somewhat fleshy (fresh), margins entire, sometimes shallowly crenate or serrate distally, sometimes undulate, apices acute, mucronate or attenuate, glabrous;

mid and distal cauline not crowded, sessile, blades lanceolate to linear-lanceolate, 10–120 × 5–16 mm, reduced distally, margins entire.

1–6 mm;

bracteoles ovate, minute, grading into phyllaries.

2–8 mm, glabrous or sparsely strigose;

bracteoles 0–4.

campanulate, 3–4.5 mm.

narrowly campanulate, 3–4 mm.

3–7;

laminae 1.5–2 × 0.5–1 mm.

(5–)11–15;

laminae 1.5–3.5 × 0.5–0.75 mm.

4–7;

corollas (abruptly ampliate) 3–3.5 mm, lobes ca. 1 mm.

8–22;

corollas 2.5–4.5 mm, lobes 1–1.5 mm.

in 3 series, strongly unequal, obtuse or rounded;

mid broadly oblong, inner narrowly so.

in 3–4 series, outer narrowly ovate to lanceolate (1.5–3 × 0.4–1 mm), unequal, obtuse to acuminate.

30–200+, apparently sometimes drooping, in open leafy, secund pyramidal, paniculiform arrays, branches recurved, leafy-bracteate, secund, proximalmost branch sometimes separated by several nodes from next.

60–100, in thyrsiform-paniculiform arrays, sometimes secund apically, (3.5–)6–26(–60) x 4–10(–15) cm, branches ascending to arching.

1.5–2 mm (4–8 translucent ribs), moderately short-strigose;

pappi 2–2.5 mm.

(narrowly obconic) 1.5–2.5 mm (ribs 5–8, broad, lighter than body), sparsely strigose;

pappi 3–4 mm.
