This paper reports the results of experiments with two heteroecious species of the Uredinales occurring on prairie grasses in Iowa. Aecidium yuccae Arth. is shown to be connected with Puccinia amphigena Diet., and evidence is presented indicating a connection between Aecidium aesculi E. & K. and Puccinia andropogonis Schw. This paper also records the occurrence in Iowa of Puccinia amphigena Diet. and Puccinia flaccida B. & Br. A check of lists compiled by Arthur (1926), Gilman and Archer (1929) and Gilman (1931, 1949) has shown that these species have not been reported from the state.
