Flora of North America species comparison

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

usually 1, ascending to erect or arching, densely spreading-puberulent to occasionally subglabrous.

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 (rosettes) present at flowering, conspicuously petiolate, petioles slightly winged distally, to 100 mm, blades cordate, 40–120 × 40–110 mm, margins coarsely sharp-serrate, apices acute to acuminate, abaxial faces moderately to densely spreading-puberulent, adaxial sparsely so or glabrate;

mid and distal cauline progressively reduced, less petiolate, blades ovate to lanceolate, less cordate distally, 40–60 × 20–30 mm, margins finely serrate.

1–6 mm;

bracteoles ovate, minute, grading into phyllaries.

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.

50–250, densely crowded, often subglomerate, in secund paniculiform arrays, proximal branches few, widely spreading, secund, elongate, distal short, recurved.

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

pappi 2–2.5 mm.

1–2 mm, sparsely short-strigose;

pappi ca. 0.5 mm (forming many-bristled crown on longer cypselae).
