160. Uromyces acuminatus ArtluTr. 



Uredo and teleutospores on Sjictrtina eynosuroides Willd. Madison; 

 La Crosse, Pammel. 

 A very -variable species, which in some of its forms can scarcely be dis- 

 tinguished from a species on several grasses from other }_aits of the 

 country, which may be a form of the variable U. dactylidis Ottb.

163. PUCCINIA THALICTRI Chevall. 



Teleutospores on Thalictruni dioicum L. and T. cornuti L. Madison;

I do not see how this can be distinguished morphologically from P. 



anemones Pers. It is usually marked with larger and more obtuse warts 



than our specimens of the latter, but European specimens of P. anemones 



sometimes have quite as coarse granulations as our P. thalictri.
