Remarks. Dietel (io) makes a remark that this fungus is closely 
related to Uromyces ovalis Diet. From my own observations, however, these 
two species evidently differ from each other in various points ; that is, in 
color and shape of uredospores, in the dimension of teleutospores and pedicels 
and also in the shape of the sorus, as shown in the following table : — 
U. ovalis 
U. coronatus
