Flora of North America species comparison

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

1–10+, erect, stout, hairy.

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 usually present at flowering, abruptly narrowed to long petioles, blades ovate to rhombic, 80–200 × 24–50 mm, firm, flat, margins entire to crenate, sometimes undulate, apices obtuse to acute, faces densely hairy;

mid to distal cauline sessile, blades ovate, 30–50 × 15–17 mm, stiff, greatly reduced distally, margins entire or finely serrate, sometimes undulate, apices acute to obtuse.

1–6 mm;

bracteoles ovate, minute, grading into phyllaries.

3–15 mm, strigillose-canescent, bracteoles 1–3, linear-lanceolate.

campanulate, 3–4.5 mm.

campanulate, 6–8 mm.

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.

9–190, in corymbiform arrays, compact or branches long and spreading, densely hairy throughout.

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

pappi 2–2.5 mm.
