Leaves cauline; alternate; sessile; blades oblong to lanceolate [pinnate] (bases sometimes ± clasping), margins often with 2–4 lobes proximally, serrate distally, faces hairy or glabrous, gland-dotted. Heads radiate, borne singly or in 2s or 3s. Involucres hemispheric or broader, 12–25+ mm diam. Phyllaries persistent, 30–50+ in 2–3+ series, distinct, ovate or obovate to oblanceolate (not keeled abaxially), margins and apices scarious (tips not notably dilated). Receptacles convex, epaleate. Ray-florets 21–34+, styliferous and sterile; corollas usually white, sometimes reddish, laminae ± ovate to linear. Disc-florets 100–150+, bisexual, fertile; corollas usually yellow, sometimes reddish, tubes ± cylindric (± gland-dotted), throats campanulate, lobes 5, deltate (without resin sacs).
