Perennials, 5–15 cm; taprooted, caudices woody, branches usually vertical or horizontal (2–10 cm), sheathed by persistent leaf bases. Stems erect, glabrous or sparsely villous, sparsely minutely glandular. Leaves basal (persistent) and cauline; basal blades sometimes 3-nerved, oblanceolate to obovate or spatulate, 25–90 × 5–17 mm, margins entire or dentate on distal 1/2 or near apices, faces glabrous, sparsely minutely glandular; cauline blades lanceolate to ovate, smaller than basal, often relatively even-sized distally (bases clasping to subclasping). Heads 1(–3) (on branches from proximal axils). Involucres 5–8 × 8–14 mm. Phyllaries in 2–3 series, sparsely to moderately hirsuto-villous, sometimes sparsely minutely glandular. Ray florets 30–50; corollas white, less commonly purplish, 6–10 mm, laminae not coiling or reflexing. Disc corollas 3.7–4.4 mm. Cypselae flattened, 1.9–2.2 mm, 2-nerved, faces sparsely strigose or glabrous; pappi: outer of setae, inner of 14–20 bristles.
