is species is characterized by the prevalence of mesospores in the 
sori, and by the aecidia occurring on Ornithogalum spp. (they have not 
been collected in New Zealand), otherwise it is identical morphologically — :

indebted to Mrs. F. W. Patterson, of the United States Department. of 
Agriculture, Mycological Exchange, for teleutospore material from which 
the above description has been drawn up. 
Arthur (1904, p. 64) proved that this is an heteroecious species. ш 
sowed aecidiospores from Ozalis cymosa Small on maize-leaves, and їп ie 
days obtained spermogones and uredosori.
