Characteristics

Perennial herb with a woody stock, glabrous except for the woolly crown and woolly hairs hidden in the leaf axils, flowering stems solitary, simple below the inflorescence branches, up to c. 60 cm tall, leafy mainly in the lower part. Leaves 3-6, passing abruptly into inflorescence bracts, up to c. 16 x 2(-4) cm, at least the middle leaf (4-)6-10 or more times as long as broad, apex acute to acuminate, base often minutely eared, clasping, sometimes slightly decurrent, margins thickened, entire or distantly and often obscurely callose-denticulate, often somewhat revolute, leathery, side nerves few, sharply ascending. Heads radiate, many on long sparsely bracteate peduncles corymbose-paniculately arranged. Involucre turbinate-campanulate, bracts (8-)12(-16), (4-)5-6 mm long, much shorter than the disc, calyculus bracts 1 or 2, very small. Rays usually 8, rarely as few as 5 or 6, occasionally up to 10, they and the disc bright yellow. Achenes c. 3.5 mm long, ribbed, glabrous.
