Remarks. The present species was first found parasitic on Panicinii 

 pniricntis on Oahu Island in Hawaii. 



Mr. T. Y0SHINAG.\ kindly sent ti.i mc the specimens of the present 

 species on Paniciun sanguinalc. The Japanese plant shows a great similarity 

 to that of Oahu, and, in fact, no points of difference between them are to be 

 seen as was identified by DiETEL (lo). The teleutosori, it is said, were not 

 found in the Oahu specimen. This is true also of our plant. I'he teleuto- 

 spores are found mixed in the uredosori.

Remarks. This species was at first included in Puccinia graminis, as 

 there are apparently no distinct morphological differences between them. 

 Eriksson and Henning (2) proved that this species has no relation to the 

 ^cidium on Berbcris and that the uredospores have the hibernating power. 

 From these physiological differences, these authors are led to consider them 

 as distinct species. In 1907, POLE EvANS(i) proved the existence of the 

 decided morphological differences between them by his cytological investiga- 

 tions of their uredo mycclia.
