Description
Perennial rosette or sparingly branched herb. Lvs spathulate or cuneately narrowed to winged petiole and obovate to oblong, with (1)–3–4–(6) pairs of rounded or sharp teeth or lobes (seldom lyrate-pinnatifid), glabrous or sparsely to densely clothed in short- or long-stalked glandular hairs on both surfaces and margins, 12–60–(120) × 3–20 mm. Peduncle often with up to 3 lvs becoming reduced and scale-like above, sometimes naked, sparsely to densely clothed in glandular hairs especially near capitulum, (2.5)–5–12–(15) cm long and 0.6–2 mm diam. at flowering, up to 15–(23) cm long at fruiting. Involucral bracts elliptic-oblong, obtuse to subacute and often fimbriate at apex, usually glandular at least near base, rarely glabrous, 2.5–4 mm long. Rays numerous, usually white, rarely flushed pink or lilac, c. 5–8 mm long. Disc yellow. Achenes obovoid-oblong, compressed or subterete, glandular, 2.5–4 mm long; pappus of few bristles 0.1–0.5 mm long.
