In 190:!, Arthur (3) made this species s}^non)'nious to Urouiyccs 

 Rottba-UiiC Arth. of Himalaj-a. 



Ill 1906, I\I(:AlI'IXi; (n writes of the present species as synonymous 

 to Piicciiiia cacao McAlp. of Australia, after the determination by DiKTEL. 



In our country as its teleutostage is not yet Iviicwn, it is still under 

 question, whether our species belong to Urouiyccs Rotllnvlluc, or to Piicciiiia 

 cacao or to Pucciuia Rottbailiu-. But one fact is certain that our species 

 has no amphispores, of wliicli AkTHLiR (5) writes in tlte case of his Urouiyccs 

 Rottbccllicc. In short, it seems to me safe in the present case to treat the 

 present species as UrcJo RotlbaHuc.

RkmakKS. The jireseiit ftnigus was first descriljed I)\- KrÜCI'.R (i) 

 under the name of Urouiyccs Kiilinii, which he had found parasitic on the 

 leax'es of suger cane in Ja\a together with Ccrcospoi a I'agiiuc Kriig. 



Later, WakRKK and Wr.XT (i) proved by the infection experiments, 

 that the fungus lacks entirel\- tlie teleutostage and gave it the present name.
