Perennials, (30–)40–100(–150) cm, cespitose; short-rhizomatous. Stems 1–5+, ascending to erect, strigose, villous, or lanate, especially distally. Leaves (grayish green) thin to firm, margins entire, apices acute, faces strigose; basal withering by flowering, petiolate, blades narrowly oblanceolate, 50–100(–150) × 4–12(–15) mm, bases attenuate, margins scabrous to ciliate; proximalmost cauline often withering by flowering (often with tufts of leaves in axils), sessile, blades linear to narrowly oblong, 30–70(–100) × 4–8(–10) mm, bases attenuate or cuneate, apices acute; distal sessile, blades 15–80 × 2–8(–10) mm, bases cuneate, sometimes auriculate. Heads (3–50+) in narrowly paniculiform arrays, branches 2–10(–20) cm. Peduncles densely short-strigose, bracts 1–6, linear-oblong, strigose. Involucres campanulate, 4–7 mm. Phyllaries in 3–6 series, narrowly oblanceolate or linear (outer) to linear (inner), unequal, bases indurate, margins entire, narrowly scarious, ciliate, green zones obovate to elliptic, apices obtuse, mucronulate, faces usually strigose. Ray florets 15–40; corollas pale violet, laminae 8–12(–15) × 1–1.5(–2) mm. Disc florets 25–70+; corollas yellow, 4–6 mm, lobes triangular, 0.4–0.8 mm. Cypselae brown, cylindric to obovoid, not compressed, 1.5–3 mm, ribs 5–8, faces hairy; pappi whitish, 4–6 mm. 2n = 36.
