Plants usually erect, usually 50–300 cm, variably tomentose, sometimes ± glabrate. Heads sometimes in tight clusters at ends of peduncles, usually long-pedunculate, elevated well above proximal leaves. Involucres usually longer than wide, 2–6 cm, subglabrous to densely arachnoid, usually without fine trichomes connecting tips of adjacent phyllaries. Phyllaries imbricate, outer and mid apices ascending to rigidly spreading or reflexed, straight, 5–20+ × usually 2–3 mm. Corollas usually ± red (white, pink, rarely purple), 23–35 mm. 2n = 30.
