* A genus reunited with Sonchus by Mr. Bentham ; but it appears to me that it 

 is really more nearly allied to Lactuca, both in structure and habit : indeed, M. Pluraieri 

 is placed in the genus Lactuca by Professor Grenier, in the " Flore de France," and 

 M. alpinum only differs from the Lactucse by its less compressed achenes, less attenuated 

 towards the apex, and not beaked below the enlarged disk fi'om which the pappus 

 springs.
