 long and one broad, perfectly entire. Corymbs copious, 

 about as long as the cauline leaves (including the peduncle) 

 much longer than those of the peduncle, which gradually pass 

 intosmall bracteason the pedicels. Male pappus white, clavate.

 Leaves an inch to an inch and a half long, generally quite 

 entire, occasionally with a solitary tooth on one or on both 

 sides, opaque, distinctly impresso-punctate on both sides, single 

 nerved. Capitula (male) solitary, pedicellate in the axils of 

 numerous small leaves or bractea?, at the extremity of the 

 common branches or on peculiar branches, so that they form 

 leafy or bracteated racemes, and are longer than the bracteae 

 when in full flower.
