* 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. Plumieri 
is placed in the genus Lactuca by Professor Grenier, in the " Flore de France," and 
M. idpinum only differs from the Lactucae by its less compressed achenes, less attenuated 
towards the apex, and not beaked below the enlarged disk from which the pappus 
springs.
