The aecidia on composites vary considerably in the form and 

 color of the spots, the arrangement of the ascidia and in the 

 size and form of the spores. In the absence of necessary 

 knowledge of the life-histories of these forms only a temporary 

 classification is possible. Their separation into varieties based 

 on the hosts is the only convenient method.
