Stems erect (bases greenish), sparsely hirsuto-villous (hairs usually retrorse), eglandular. Leaves basal (persistent) and cauline; (bases greenish) proximal blades oblanceolate to oblanceolate-spatulate, 20–50 × 3–10 mm, gradually reduced distally, becoming linear (rarely slightly subclasping), margins entire, faces sparsely villous-hirsute, eglandular. Heads 1(–3). Involucres 6–9 × 12–17 mm. Phyllaries in 3–4 series, densely villous to hirsuto-villous, eglandular. Ray florets 45–90; corollas blue to purple, 7–13 mm, laminae not coiling or reflexing. Disc corollas 5–6.5 mm. Cypselae 1.5–2.2 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 18–25 bristles.
