Flora of North America species comparison

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

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

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.

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.

1–6 mm;

bracteoles ovate, minute, grading into phyllaries.

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

bracts grading into phyllaries, sparsely hirtellous.

campanulate, 3–4.5 mm.

turbinate, 8–12 mm.

3–7;

laminae 1.5–2 × 0.5–1 mm.

6–10;

laminae 3–4 mm.

4–7;

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

11–14;

corollas 6 mm, lobes ca. 2 mm.

in 3 series, strongly unequal, obtuse or rounded;

mid broadly oblong, inner narrowly so.

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

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

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.

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

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

pappi 2–2.5 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.
