Flora of North America species comparison

1–20+, erect, proximally sparsely to moderately strigoso-villous, distally usually moderately to densely so.

usually 1, erect, glabrous, short hispido-strigose in arrays.

basal 0;

proximal cauline sessile, blades narrowly to broadly oblanceolate, 35–75(–100) × (6–)7.5–14(–20) mm, proximal much smaller, tapering to bases, margins subentire or finely serrulate to coarsely, sharply serrate (teeth 0–9 per side), ciliate, 3-nerved, sometimes obscurely so, apices acute, abaxial faces glabrate to sparsely short-strigose, adaxial glabrous;

mid to distal cauline sessile, blades oblanceolate, becoming lanceolate distally, 20–60 × 4–8(–11) mm, largest near mid stem, somewhat to much reduced distally, margins entire or finely serrulate, rarely serrate (teeth 1–8 per side), usually becoming entire to sparsely serrulate distally, ciliate, apices acute, faces glabrous or sparsely strigoso-villous, more so along abaxial nerves.

basal and proximal cauline tapering to long petioles that partially sheath stems;

blades oblanceolate, 100–350 × 5–60 mm, margins subentire to serrate, apices acute;

mid to distal sessile, not sheathing stems, blades lanceolate, 20–50 × 5–10 mm, much reduced distally, margins entire.

2–7 mm, sparsely to moderately short strigoso-villous;

bracteoles 1–3, linear, rarely minutely stipitate-glandular.

1–4 mm, glabrous or sparsely strigose.

narrowly campanulate, 2.5–3.5(–4) mm.

outer ovate, acute, inner linear-oblong, obtuse.

12–500+, sometimes secund, in short to long, thyrsiform or narrowly secund-pyramidal paniculiform arrays, usually congested, club-shaped to rarely wand-shaped, (2.5–) 10–20 × (2–)4–8(–10) cm, branches usually ascending or sometimes arching spreading.

35–230 in elongate paniculiform arrays, sometimes narrow and secund pyramidal, usually narrowly to broadly, non-secund thyrsiform;

branches strongly ascending with non-secund heads to arching with heads secund.
