Dr. P. Hennings has recorded a new species, Uredo breviculmis, on 

 Carex breviculmis var. leucochlora Bunge, from Japan, and seeing that the 

 host plant is a native of Japan as well as of Australia, I forwarded some of 

 this material to him, and he replied that he scarcely thinks the two species 

 are identical.
