Plants 20–60(–80) cm, glabrous; caudices short or crowns. Stems 1, erect, slender. Leaves: basal tufted, tapering, petiolate, petioles 20–100 mm, blades oblanceolate or elliptic, 30–120 (including petiole) × 5–15 mm, obtuse to rounded; cauline sessile, blades oblanceolate to linear-lanceolate, 5–80 × 4–1.3 mm, abruptly reduced proximally, becoming bractlike proximal to arrays. Heads 5–20(–50), in slender racemiform or paniculiform arrays, sometimes secund and apically recurved, more often erect and not secund, sometimes compact and somewhat rounded to only slightly elongate. Peduncles 2–25 mm; bracteoles crowded, linear, 1–2 mm, grading into phyllaries. Involucres broadly campanulate, 3.5–5 mm. Phyllaries in 3–4 series, linear-lanceolate, strongly unequal, acute to slightly acuminate or cuspidate, glabrous. Ray florets 6–14; laminae 2–3 × 1–2 mm. Disc florets mostly 12–30; corollas 3.5–4 mm, lobes 0.5–0.75 mm. Cypselae 1.5–2 mm, sparsely finely strigose; pappi (basally broader and flattened, fused to varying lengths) 3–4 mm (somewhat clavate). 2n = 36.
