Leaves 7–15 cm long, with l:w ratio c. 2.5–6, undivided or deeply lobate to subpinnatisect proximally, with 2–5 ± triangular, or occasionally oblong, lobes per side, usually undivided or weakly lobate in distal half; base with well-developed auricles; upper surface somewhat hispid; lower surface hispid, occasionally slightly cobwebby, sometimes tinged purple. Capitula numerous per stem; calycular bracteoles 4–6, 1–2.5 mm long; peduncle and calyculus not cobwebby at anthesis; involucre 4.5–6.0 mm long, 1.3–1.8 mm diam.; bracts predominantly (9–) 11–13, glabrous. Florets 18–35. Achenes narrowly obloid, 1.5–2.2 mm long, red-brown, glabrous or with papillose hairs in lines or narrow bands, occasionally slightly scattered; l:w ratio of hairs c. 3. Pappus 4–6 mm long.
