Phyllaries in 3–5 series (often purple-tipped; margins of inner narrowly scarious), glabrous, minutely glandular. Ray florets 12–21; corollas white, drying bluish, 5–6 mm, laminae coiling. Disc corollas 3.5–4 mm (throats slightly indurate, not inflated). Cypselae 1.6–2.5 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 18–26 bristles.
