Dr. Schultz rightly observes that the original M. nudi- 
caulis, Less. is a mere section of Lactuca, distinguished 
solely by its achenia having a beak shorter than in the 
other species. "We shall show hereafter that tbe remaining 
species, placed by DC. in this genus, together with his variety 
B. of the original species, belong to the genus Rhabdotheca, 
Cass. Microrhynchus therefore must be entirely abandoned.
