The species here enumerated were in part identified by the writer; 

 but the whole collection was worked over by H. H. Hume and the 

 credit of naming the species belongs to him. I desire to express my 

 thanks to Dr. W. G. Farlow, who has so kindly examined several of 

 the Uredinece and some of the Exoasci, and to J. B. Ellis for the iden- 

 tification of a few species.
