Heads 1(–3) (on branches from proximal axils). Involucres 5–8 × 8–14 mm. Phyllaries in 2–3 series, sparsely to moderately hirsuto-villous, sometimes sparsely minutely glandular. Ray florets 30–50; corollas white, less commonly purplish, 6–10 mm, laminae not coiling or reflexing. Disc corollas 3.7–4.4 mm.
