Flora of North America species comparison

1–5, sparsely to moderately strigoso-puberulent.

1–3, terete, shallowly multicostate, glabrous, sparsely to moderately hirtellous distally (arrays).

basal petioles 3–5 cm, blades oblanceolate or spatulate to ovate or rotund, 2–4 cm (excluding petioles);

cauline (numerous) subsessile or sessile, blades elliptic or lance-elliptic to ovate, mid mostly 25–50(–65) × 10–25 mm, distal much reduced;

branch leaf petioles 1 mm, blades ovate, 5–15 (excluding petioles) × 2–10 mm.

basal and proximal cauline winged-petiolate;

blades mostly spatulate to oblanceolate, 100–150 × 15–32 mm, tapering, margins distally coarsely but shallowly serrate, apices acute to narrowly rounded, often narrowed to short, often brown callused tips;

mid to distal cauline progressively more narrowly oblanceolate and acute, then to elliptic or lanceolate-elliptic, 35–60 × 6–10 mm, reduced distally, grading into widely ascending to spreading or reflexed bracts;

faces abaxially pale, midnerves raised, deep green, level reticulum of branch nerves, margins entire, ciliate, adaxially deep green with only impressed midnerve evident.

linear, 1–3 mm, bracteate.

stiffly, widely ascending, angulate, slightly compressed, stubby-bracteolate;

bracts grading into phyllaries, sparsely hirtellous.

narrowly campanulate, 3–5 mm.

turbinate, 8–12 mm.

0(–2).

6–10;

laminae 3–4 mm.

4–8;

corollas 3 mm, lobes 1 mm.

11–14;

corollas 6 mm, lobes ca. 2 mm.

in 3–4 series, lanceolate, strongly unequal, margins ciliate, apices acute, glabrous.

(in 3–4 series) 1–1.3 mm wide, unequal, pilose-ciliate;

outer mostly green, oblong, blunt, inner spatulate or linear-oblanceolate.

75–200 in open paniculiform arrays, branches divaricate, ascending to recurved, weakly to strongly secund, to 50 cm, secondary branches less than 3 cm.

10–50 (1–5+ per branch), in racemiform or narrowly paniculiform arrays, mostly with primary branches widely to narrowly ascending, proximalmost usually longest.

2.5–3 mm, moderately short-strigose;

pappi 2 mm.

cylindric to somewhat compressed-obconic, 1.5–4 mm, typically 5-ribbed, glabrous, abruptly narrowed to short “neck” surmounted by narrow, brownish pappus disc;

pappi (white) 3–4 mm.
