 The rust on red clover is widely distributed in the state and prob- 

 ably occurs wherever this host is cultivated. It is, however, rare on the 

 crimson clover; only one other collection in America is known to the 

 writer, and that was collected in South Dakota. This species is readily 

 separated from the only other long cycled Uromyces on Trifolium oc- 

 curring in North America by the uredinial pore characters. In the 

 species under discussion the pores are 4-6, scattered, while in U. Trifolii 

 the pores are 3-4 in an equatorial zone.
