species of Puccinia in our country on AntndincUa anouiala. On this point, I 

 have sufficient reason to doubt its validity. 



I obtained, by the kindness of Prof. S. KUSANO, both of the type speci- 

 mens on which DiETEL based his determination. In the course of my study 

 on both of these type specimens, my attention was drawn to the similarity 

 between them. The pedicel of Puccinia AritndincUac aiwmalac is hyaline or 

 light brownish yellow in color ; while that of Puccinia grainiiiis is also light 

 brownish or sometimes hyaline. Thus, to distinguish them by the color of 

 the pedicel becomes totally impossible. 



The color of the pedicel is not an essential factor in the point of 

 classification in Puccinia, at least, it is true in the case of Puccinia on 

 Gramineae. I-'or cxamjile, the pedicels of Puccinia crythropus, P. riifipcs, 

 P. Eitlaliac and P. AnindiitcUac and also those of many other species vary 

 pretty often in their color. So, simply from the color difference of the 

 podiccls the so called Puccinia graminis on Aruiuiinclla may not be different 

 from PeksOON's Puccinia graminis. But uredospores which were acciden- 

 tally found on the type specimen of the so called Puccinia graminis, diffe;r 

 utterly from those of /'. graminis, but corresjiond exactly to those of the 

 present species. I wish, for the reasons above mentioned, to include the 

 Myogi specimen in Puccinia Arundincllac anomalac. 



As has already been mentioned, this species is distinguished from 

 Puccinia Arundincllac of Himalaya by the slender teleutospores. But it must 

 be remenbered that the dimensions of some of our species approach that of 

 P. Arundincllac. Among specimens, collected at Garugawa, Tsurumi and 

 other places, there were few spores which measure above 42 //. Generally, 

 while young, the color of the teleutospore is light colored and slender in 

 shape, but when ripened its color is darker and more or less roundish in 

 shape. After all, our species may not be different from the Himalayan 

 species. Further study is needed to settle this point.
