Perennials, 15–60 cm; rhizomatous, fibrous-rooted, primary rhizomes relatively slender, producing slender, herbaceous, scale-leaved, stoloniform rhizomes (rhizomes often not collected). Stems erect to ascending (usually abruptly dilated proximal to heads), villous (more densely so on proximal 1/2), eglandular. Leaves basal (persistent) and cauline; basal blades oblanceolate to obovate or suborbiculate, subspatulate, 20–130(–180) × 6–30(–50) mm, cauline gradually reduced distally (bases clasping and slightly auriculate), margins usually dentate to denticulate, rarely entire, faces sparsely to moderately hirsute to hirsuto-villous, sometimes glabrate or glabrous (especially adaxially), eglandular. Heads 1–4(–9). Involucres 5–7 × 6–20 mm. Phyllaries in 2–3(–4) series, sparsely to moderately hirsute to hirsuto-villous (cross walls not distinctly colored), minutely glandular to stipitate-glandular. Ray florets 50–80(–100); corollas light blue to purplish, pink, or white, 6–10 mm, laminae coiling tardily at tips. Disc corollas 4.5–6 mm. Cypselae 1.3–1.8 mm, 2(–4)-nerved, faces sparsely strigose to glabrate or glabrous; pappi: outer 0 or of setae, inner of (22–)28–36 bristles.
