Found on the Continent. 



Obs. — Easily distinguished from all forms of J/, emaq/i/iafa by 

 its colour, and the polished epidermis and close texture of its leaves ; 

 and from M. FtincMi by the same characters and its obtuse lobes. 

 These are the most likely species which it could be mistaken 

 for, without a careful study of the involucre. Sometimes the 

 perianth is a true one, and adnate to the lower portion of the 

 bracts, but generally it is free and not perfectly tubular.
