Leaves basal (usually persistent through flowering) and cauline; basal blades spatulate to broadly or narrowly oblanceolate to linear, (10—)30—150(—170) × 5—15(—21) mm, cauline usually gradually reduced distally, continuing to near heads, margins entire or shallowly to deeply serrate or crenate, faces glabrous or glabrate to sparsely strigose or strigoso-hirsute, eglandular. Heads 10—200+ in loosely corymbiform to paniculiform-corymbiform arrays (on distal branches). Involucres (2—)3—4 × 5—12 mm. Phyllaries in 2—4 series, glabrous, strigose, or sparsely hirsute, sometimes minutely glandular. Ray florets 50—100; corollas white, less commonly pinkish or bluish, 4—6 mm, laminae coiling. Disc corollas 1.5—2.5 mm (throats sometimes slightly indurate and inflated). Cypselae (0.5—)0.9—1.2 mm, 2-nerved, faces sparsely strigose; pappi: outer crowns of setae or scales, inner 0 (rays) or of 8—15 bristles (disc).
