Aecidium Compositarum, Auct. Amer. p. p. 



NOTE. Very little is known in regard to the development of the Aecidia 

 on Composite in America, but some belong to autcecious and others to heter- 

 cecious species. The number of references is so great and in some instances 

 they are so uncertain that for practical use by mycologists it has seemed best 

 under Aecidium Compositarum to group the Aecidia on all the genera of 

 Composites. 



Where in the original references no particular host-genus is mentioned, 

 the references are grouped chronologically with the heading of Miscellanea. 

 Where definite genera are mentioned, the hosts are arranged alphabetically, 

 each with its references; e.g., all references to Aecidia on Ambrosia are 

 placed under Aecidium Compositarum, var. Jmbrosice.
