Characteristics

Perennial herb with a rhizomatous stock, glabrous except for the woolly crown and wool hidden in the leaf axils, roots thong-like, flowering stems often up to c. 60 cm tall, exceptionally to 1 m, often several from one crown, simple below the inflorescence branches, leafy mainly in the lower part. Leaves up to 12 x 1.5 cm, crowded on the lower half of the stem, becoming smaller and more distant upwards, oblong or lanceolate-oblong, apex acute to subacuminate, base usually narrowed, sessile, margins entire or distantly callose-denticulate, often somewhat revolute, somewhat fleshy, glaucous. Heads discoid, solitary or up to c. 8 on long nearly nude peduncles corymbose-paniculately arranged. Involucre turbinate-campanulate, bracts 12(-16), 8.5-11 mm long, shorter than the disc, broad, flat, leathery, calyculus bracts 1 or 2, very small. Flowers bright yellow. Achenes 5-6 mm long, cylindric, ribbed, glabrous.
