Pcricline of numerous imbricated scales, generally with a ter-

 the disk perfect, those of the circumference generally larger and 

 radiant, neuter. Filaments free, papillose ; anthers without basal 

 appendages. Achenes obloug-ovoid, laterally compressed, smooth, 

 and without raised lines, attached by the side above the base ; 

 epigynous disk with an entire border. Pappus persistent or cadu- 

 cous, sometimes absent, or very short, sometimes of elongated 

 denticulated hairs, arranged in several rows, free at the base, the
