Stems solitary or many, ca. 5 mm in diam., erect, simple or branched above middle, nearly glabrous. Basal and lower stem leaves petiolate; leaf blade lanceolate or broadly elliptic or elliptic, 6–15 × 4–11 cm, fleshy, lyrately pinnatisect or pinnately lobed, both surfaces green, glabrous; lateral lobes ovate to oblong, margin entire or subentire; terminal lobes ovate to rounded, or triangular, larger, margin subentire, apex acute to obtuse. Middle and upper stem leaves petiolate, ovate to obovate, apex acute to obtuse. Uppermost leaves short petiolate or sessile. Capitula numerous, in a corymbiform synflorescence, pedunculate. Involucres campanulate, 3–4 mm in diameter. Phyllaries in 5–8 rows, glabrous, apex acute or acuminate, purplish-green, margin membranous; outer phyllaries elliptic, 8–15 × 2–3 mm; middle phyllaries narrowly ovate-elliptic, 4–5 × 2–3 mm; inner phyllaries linear-lanceolate, 2–3 × 1–2 mm. Corolla purple, 1.3–1.6 cm, tube ca. 10 mm, limb ca. 6 mm. Achenes reddish brown, cylindric, 2.5–3 mm, glabrous.
