Hcnn.). Three other specialized forms also have been given independent 

 specific positions to which I shall refer later on. 



The aecidial stage of the species under consideration is known to occur 

 on Artclntsa arvensis and A. officinalis in Europe. As there are no species 

 of Ancluisa in our flora, the aecidial stage may have been altogether 

 abbreviated in our country. Ancluisa officijulis is cultivated on our College 

 farm, but we have not yet found any /Ecidium growing upon it. 



The specimens of /'//(■(■/«/(r i/is/'crsa which I have examineti are rather 

 scanty in number, as rye is not yet widely cultivated in our country. I have 

 specimens only from Sapporo and Morioka. In the vicinity of Sapporo, rye 

 is annually attacked rather severely by the uredospores of this fungus. Its 

 teleutospores, however, are seldom found.
