 Aecidium Compositarum, var. Prenanthis, Auct. Amer. 



NOTE. It is uncertain to what species the following references to aecidin 

 on Prenanthes relate, but apparently some are the aecidia of Puccinia 

 Prenanthis^ (P.) as limited by Lindroth, q. v. As far as we know the name 

 Aecidium Prenanthis on Prenanthes does not occur in American literature 

 except incidentally in Pk. Kept. N. Y. Mus. 50: 115. March 1898. See
