specimens are distinguished by dark brown (almost black) involucral 

 bracts and longer and wider rays. This is certainly not identical with 

 the European form. We agree with Torr. & Gray in thinking that the 

 northern form is perennial. It is not annual as the specimens obtained 

 by Dr. Bell amply prove. Better specimens may show that it is 

 entirely distinct from the European plant.
