Leaves spreading; petioles of proximal leaves 1–2.5 cm; blades of midstem leaves suborbiculate to widely ovate, 3.5–5 × 3–5 cm, base obtuse to cordate, symmetric, apex obtuse to rounded, rarely acute. Involucres: peduncle 4–25 mm; involucres erect or ascending, 13–23 mm; bracts 5, 50% connate, 15–20 mm, apex acute to widely ovate. Flowers 6 per involucre; perianth magenta, funnelform, 1.5–2.5 cm. Fruits light-brown, with 10 slender ribs visible when wet, widely obovoid to ellipsoid, 6–7.5 mm, tuberculate, glabrous or very sparsely puberulent, secreting mucilage most abundantly on ribs when wetted.
