seed in the greenhouse : Hordeum jubatum, Elymus canadensis, 

 E. virginicus, and Hystrix patula. Both species of Elymus were 

 very heavily infected and Hordeum was slightly infected. An- 

 other inoculation was made on Hordeum jubatum and slight 

 infection followed. As the plants of Hordeum jubatum used in 

 these experiments were not in a healthy condition little value can 

 be placed on the results which tend to show that Hordeum juba- 

 tum is not a congenial host in Eastern Canada. Arthur has 

 shown by several cultures that the aecia on Impatiens are con- 

 nected with Puccinia Impatientis on Elymus.
