This family also called 

 flosculose, has been stated to be very deficient 

 in North America ; but it is a mistake, 5 Genera 

 alone Lactuca, Eunoxis, tiieracium^ JVIorp- 

 balia and Krigia, include nearly 100 species; 

 being as numerous as the Asters, they have 

 been equaly involved in obscurity by blending 

 or overlooking sp. which require careful mono- 

 graphs, such as I have undertaken ; but must 

 delay at present and only give a few striking 

 novelties, 'as I wish to confine this flora to 1000 

 articles at present. This continent is tbe cen- 

 tral seat of Lactuca as it is of Vhis and Quer-

 Lactuca elongata of our blind botanists con- 

 tained 12 or 15 sp.with leaves smooth or rough,
