Heads 1. Involucres 4–7 × 6–15 mm. Phyllaries in 2–3 series (commonly purplish to purplish black, sometimes only at tips, midvein region greenish), hirsute, densely minutely glandular. Ray-florets 20–37; corollas usually blue or purple, rarely white, 4–10 mm, laminae tardily, often only slightly, reflexing. Disc corollas 3.7–5.3 mm (throats tubular). Cypselae 2.3–2.8 mm, 2-nerved, faces sparsely strigose; pappi: outer of inconspicuous, fine setae, inner of 15–25 bristles. 2n = 18.
