Perennials, 20–70 cm, colonial and cespitose, ± glaucous, sometimes stipitate-glandular distally; rhizomes woody, elongate and creeping, or short, erect, branched. Stems 1–7+, erect, sometimes branched proximally, straight, glabrous proximally, sometimes thinly scabridulous distally. Leaves cauline; proximal reduced, withering by flowering, firm; sessile; blades oblong or elliptic-oblong to lanceolate (sometimes narrowly), 40–120 × 5–25 mm, bases ± clasping, sometimes cuneate, main veins ± marked, margins entire, indurate, sparsely to densely scabridulous, apices acute to obtuse, mucronate (margins recurved at apex), faces glabrous. Heads 2–116+ usually in corymbiform, sometimes in open, paniculiform arrays. Peduncles glabrous to sometimes thinly scabridulous or villosulous; bracts 0–2, foliaceous, margins villose-ciliate or glabrous. Involucres campanulate, 6–9 mm. Phyllaries (15–35) in 4–5 series, keeled or rounded, ovate or oblong (outer) to lanceolate (inner), unequal, membranous, bases indurate, green zones in distal 1/5–1/3 or less (outer), reduced to midnerve or none (inner), margins erose, narrowly scarious, hyaline, sometimes purplish distally (inner), entire to villoso-ciliolate, apices ± appressed, obtuse or acute (outer), often purple and acute or acuminate (inner), sometimes apiculate, faces glabrous. Ray florets (8–)10–15(–19); corollas pale lavender, 8–18 × 0.7–1.3 mm. Disc florets 12–32; corollas yellow turning reddish purple, barely or not ampliate, 6.8–7.5 mm, tubes narrowly cylindric, shorter than funnelform throats, lobes spreading, lanceolate, 0.7–1.3 mm. Cypselae tan to stramineous, fusiform, ± compressed, 3.8–4.8 mm, ribs 7–10 (stramineous), faces glabrous or sparsely strigillose; pappi of (ca. 37) yellowish to cinnamonish bristles 6.4–7.2 mm.
