    Plants 50–200 cm;
    rhizomes short to long-creeping.
    Stems 1–40+, usually short-hairy throughout, sometimes proximally glabrescent.
    proximal cauline usually withering by flowering;
    sessile or subpetiolate, tapering to bases;
    blades oblanceolate, 95–150 × 16–20 mm, relatively thick and firm, entire to serrate along distal 1/2, strongly 3-nerved, apices acute to acuminate, abaxial faces finely strigose, more so along nerves, adaxial ± scabrous;
    mid to distal cauline blades oblanceolate (proximally) to lanceolate (distally), mid (30–) 45–100 (–170) × (5–) 7–16 (–25) mm, much reduced distally [(15–) 25–55 × (3–) 4.5–10 (–17) mm], margins finely serrate (teeth 0–6 (–14) per side on mid), distally usually becoming entire or remotely serrulate, adaxial faces ± scabrous, abaxial moderately strigillose, densely villoso-strigillose along nerves, distal sometimes minutely stipitate-glandular.
    Heads (15–) 100–1200+, secund, in secund, pyramidal, paniculiform arrays, branches divergent and recurved, sometimes ascending-divergent, sometimes merely club-shaped thyrsiform in small plants, 5–30 × 2–25 cm (often 1.5–2 times as long as wide in southern plants).
    Peduncles 1–3.5 mm, moderately densely short hispiduloso-strigillose, sometimes minutely stipitate-glandular;
    bracteoles linear, sometimes minutely stipitate-glandular.
    Involucres narrowly campanulate, 2.5–4.5 mm.
    outer lanceolate, acute, inner linear-lanceolate, margins rarely minutely stipitate-glandular, apices acute to obtuse.
    Ray-florets (5–) 8–13 (–17);
    laminae 0.7–1.5 (–2) × 0.1–0.4 (–0.5) mm.
    Disc-florets (2–) 3–6 (–9);
    corollas usually 2.3–3.6 mm, lobes 0.5–0.9 (–1.2) mm.
    Cypselae (narrowly obconic) 0.5–1.5 mm, sparsely to moderately strigillose;
    pappi 2.5–3.5 mm.
