This Aecidium differs decidedly from Aec. Cassiae Bres. in having 

 considerably smaller spores than the African species, and is without ques- 

 tion distinct from it. Ellis & Kellerman"s name was never established, 

 as far as the writer can. determine and not now an available one. This 

 being the case, this Aecidium is still unnamed.
