Flora of North America species comparison

1–5+, sparsely to moderately short strigose or villous.

usually 1–3, ascending to erect, scabrous to loosely puberulent.

basal withering by flowering, petiolate, smaller to much smaller than cauline, blades oblanceolate, margins serrate;

cauline sessile, blades elliptic-lanceolate or -oblanceolate, mid 80–140 × 2.5–4 mm, distally reduced, usually membranous, bases tapering, attenuate, margins sharply toothed along much of length to nearly entire, ciliate, abaxial faces short-pilose along small and large nerves, adaxial short-pilose along larger nerves.

basal and proximal usually withering by flowering, tapering to long-winged petioles, blades oblanceolate, 30–100 × 7–20(–30) mm, margins serrate or crenate, mid usually largest, apices acute to obtuse, acuminate, faces scabrous;

mid and distal cauline subsessile (1 mm) or sessile, blades (sometimes ± shiny) elliptic to oblanceolate, 10–50 × 5–15(–25) mm, greatly reduced distally, grading into bracts, firm, bases convex-cuneate to rounded, margins finely serrate, often 3-nerved, nerves usually distinct abaxially, faces distinctly scabrous.

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

0.5–2 mm;

bracteoles 1–5, linear-lanceolate to ovate, minute, grading into phyllaries distally.

in ca. 3 series, strongly unequal, erect to slightly squarrose-tipped, lanceolate, apices acute, glabrate, sparsely to moderately, finely stipitate-glandular.

in 3–4 series, unequal, oblong, midnerves swollen distally, obtuse or acute to slightly acuminate.

5–160 (2–10+ more per short branch cluster), in narrowly elongate paniculiform arrays, branches usually 1–6 cm (much longer in damaged plants, sometimes 1–3 proximal branches much elongated in undamaged plants), ascending and bearing short terminal racemiform or paniculiform clusters.

20–260, in paniculiform arrays, narrowly to broadly secund, pyramidal, branches recurved, secund.
