The Mexican collections of this species of rust do not vary in any noticeable 
way from those made in the United States. Uromyces obscurus D. & H. was 
founded on a Phaseolus rust having what was taken to be a peculiar form of 
Aecidium, but which proves to be a species of Synchytrium. This name is there- 
fore a synonym of U. appendiculatus.
