Cauline leaves gradually reduced (sessile, subentire). Heads 1–6+ in open to compact, subumbelliform arrays. Peduncles bracteate (bractlets cyanic or reddish), glabrous or sparsely tomentose distally. Calyculi conspicuous (bractlets deep red or at least apices deep red to purple). Phyllaries 13 or 21, deep red or green (then tips deep red to purple), 7–10 mm, glabrous. Ray florets 0 or 8–13; corolla laminae (deep orange-yellow) 5–7 mm. Disc florets 60–80+; corolla tubes 1.5–2.5 mm, limbs 2.5–3.5 mm. Cypselae 1–1.5 mm, glabrous; pappi 3–4.5 mm. 2n = 46, 130+.
