Dicaeoma seymouriana Arthur 

 (Puccinia seymouriana Arthur) 

 Telia stage on leaves ofSpartinia michauxiana Hitchc. 

 South Bay, Madison county, on shore of Oneida lake. H. D. House. 

 August 17, 191 7. The sori appear upon the rough or under side of 

 the leaves and between the veins, and hence is c|uite different from 

 Puccinia fraxinata (Schw.) Arthur, which occurs upon 

 the same host. The aecial stage of D. seymouriana occurs 

 at the same locality upon leaves of C e p h a 1 a n t h u s o c c i d e n - 

 talis L. and appears early in summer. Both of the host plants 

 are ver} common and often grow together along the shores of 

 Oneida lake and it is probable that the rust will be found at other 

 places around the lake.
