The ecidia on composites vary considerably in the form and 
color of the spots, the arrangement of the ecidia 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.
