    Plants 30–150 (–200) cm;
    rhizomes short to long creeping.
    Stems 1–20+, erect, glabrate proximally or sparsely strigoso-villous, becoming more densely so distal to mid-stem.
    proximal to mid cauline usually withering by flowering, tapering to sessile bases, blades narrowly ovatelanceolate, 50–190 × 5–30 mm, margins sharply serrate, 3-nerved, apices acuminate, abaxial faces glabrous or more commonly hairy along main nerves, adaxial glabrous or slightly scabrous;
    mid to distal similar, 30–50 (–120) × 8–12 mm, largest near mid-stem, reduced distally, margins usually serrate or serrulate (teeth 3–8), sometimes entire proximal to arrays.
    Heads (70–) 150–1300+, secund, in secund pyramidal-paniculiform arrays (obscurely so and club-shaped thyrsiform in small plants or shoots with small arrays), branches divergent and recurved, branches and peduncles hairy.
    Peduncles 3–3.4 mm, bracteoles 0–3, linear-triangular.
    Involucres narrowly campanulate, 1.7–2.5 (–3) mm.
    Ray-florets (5–) 8–14 (–18);
    laminae 0.5–1.5 × 0.15–0.3 (–0.5) mm.
    Disc-florets (2–) 3–6 (–8);
    corollas 2.2–2.8 (–3) mm, lobes 0.4–0.8 (–1) mm.
    Cypselae (narrowly obconic) 1–1.5 mm (ribbed), sparsely strigose;
    pappi 1.8–2.2 mm.
