laries in 2 series ; those of the inner series equal, in 1 row, those of 
the outer in several rows, much shorter and frequently spreading 
or recurved. Clinanth naked. Achenes cylindrical-oblong, very 
slightly compressed, muricated towards the apex, terminated by 
a slender beak, which is surrounded by short spines at the base. 
Pappus of white filiform simple hairs. 
Herbs, with the leaves all radical. Scapes almost always 
1-flowered, fistulous. Anthodes large, yellow ; the outer florets 
often olive or red on the back. Phyllaries reflexed after the fall

The name of this genus of plants comes from rapaaaut (tarasso), I change, from its
