Biennials or perennials, 7–50(–70) cm; rhizomatous, caudices or rhizomes relatively short and thickened, simple or branched, usually appearing merely fibrous-rooted. Stems erect or slightly basally ascending, hirsute or hirsuto-villous to strigose or glabrate, eglandular. Leaves basal (persistent) and cauline; basal blades oblanceolate to oblanceolate-spatulate, 40–150 × 3–15 mm, margins usually entire, sometimes shallowly dentate, faces hirsute or hirsuto-villous to sparsely strigose or glabrate, eglandular; cauline blades usually becoming lanceolate, abruptly or gradually reduced distally (bases sometimes subclasping). Heads 1–15. Involucres 5–9 × 10–20 mm. Phyllaries in (2–)3–4 series (greenish), hirsute to strigose, eglandular. Ray florets 125–175; corollas white to pink or blue, 8–15 mm, laminae (nearly filiform) coiling tardily at tips. Disc corollas 4–5.5 mm. Cypselae 1.2–1.5 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 16–20 bristles.
