 I am in the opinion of the genus Ixeris is too distinct from 

 Lactuca or Lactuca sect. Scariola to class under one head in both its 

 habits and the form of achenes. Chorisma is a section of Ixeris having 

 stolones. Our Crepidiastrum is nearer to Ixeris than to Crepis, and I 

 second Makino's opinion in this point ; still it keeps some relations to 

 Crepis. And if our Crepidiastrum and Paraixeris should be reduced to 

 Crepis or Lactuca the latter two genera must be one and the same 

 genus.
