Perennials, 5–25(–30) cm; taprooted, caudices relatively thick, usually branched. Stems decumbent-ascending (greenish proximally), usually densely hirsute to hirtellous (hairs spreading to deflexed, gradually attenuate, basal cells erect), sometimes strigose (in Saskatchewan and Yukon), eglandular. Leaves basal (persistent) and cauline; basal blades (1–)3-nerved, narrowly oblanceolate to spatulate, (10–)20–90(–120) × 2–15 mm, margins entire (apices rounded to obtuse), faces densely hirtellous, eglandular; cauline blades oblong-ovate to linear, ± reduced distally. Heads 1–4 (branches from distal 1 / 2 of stem). Involucres 4–7 × 9–18 mm. Phyllaries in 3–4 series, densely hirsuto-canescent to hirtellous (hairs spreading), moderately minutely glandular. Ray florets 30–100; corollas white to bluish, 5–15 mm, laminae coiling. Disc corollas 3–4.4 mm. Cypselae 1.7–2.2 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae or scales, inner of 15–25 bristles. 2n = 18, 36.
