Characteristics

Perennial herb up to c. 60 cm tall, stock stout, woody, crowned with thin fibrous leaf bases, roots with fusiform tubers towards the tips, flowering stems simple or sometimes forking once near the base, forking above into the compound inflorescence, glabrous or woolly-cobwebby, glabrescent, distantly leafy. Leaves mostly radical on long wiry petioles, up to c. 40 x 4.5 cm, about half the length petiolar, blade lanceolate to elliptic or sometimes narrowly ovate, apex acute or subacute, base gradually or more abruptly contracted into the petiole, margins callose-denticulate, subrevolute, ciliate, both surfaces thinly cobwebbed at first (always ?), soon glabrous; cauline leaves similar but soon sessile, ear-clasping, passing rapidly into linear-lanceolate, acute bracts. Beads radiate, up to c. 20 on long sparsely bracteate peduncles corymbose-paniculately arranged. Involucre campanulate, bracts c. (12-)20, 8-11 mm long, about equalling the disc, nerves resinous, calyculus bracts few, sub-biseriate, about half to two thirds as long as the involucre, often thinly cobwebby, sometimes merely with glandular margins. Rays (8-)13, long, spreading, they and the disc yellow or orange-yellow, corolla lobes with a median line running back down the inflated part of the tube. Achenes not seen, ovaries glabrous or rarely with a few minute cilia.
