There are no definite clues as to relationship for this characteristic, 

 conspicuous Accidiiiiii. It is of the typical heteroecious type and may pos- 

 sibly belong with some heteroecious telial form, within its range, on a 

 host other than a grass or sedge.

From field observations, I'rof. E. W. D. Holway is reasonably certain 

 that this Accidiuni belongs with a coronate /'»c(/» /a inhabiting Agiopi/- 

 i(/n and Elymiis in the Canadian Rockies. Later Mr. E. Bethel found the 

 same coronate form on Bromns and Calamagrostis in the mountains of 

 C'olorado intimately associated with the same Aecidium. From the geo- 

 graphical distribution of these alternate forms, this connection seems very 

 likely.
