the Uromyces and Puccinia genera of the Uredinee; in fact, this 
species must be regarded as one of the connecting links between the 
two. The spores are of two kinds, one and two-celled, the one-celled 
being globose to subglobose, and measuring 19 X 28.

The two-celled spores are of three kinds : some have the septum 
transverse, in some it is oblique, while in others it coincides with 
the axis of the spore. The measurements do not differ materially from 
those given for the one-celled spores. The one-celled forms are much 
more numerous and the epispores of all are thick and smooth. 
_ In 1884, Dr. Trelease’ described a species occurring on Bromus 
ciliatus and called it P. tomipara. He says, “this species is remarkable
