that the teleutospores measure " 28-24^ " is undoubtedly a 

 misprint for 28-34, f° r trie author everywhere else places the 

 larger number last. 



The type material of Dietel's species, which was gathered 

 in Kansas on Chloris verticittata, has been examined, and 

 does not differ materially from the Mexican collections. The 

 gathering was made in the last of March and was consider- 

 ably weathered. This undoubtedly accounts for the yellowed 

 walls of the uredospores and for the more delicate and twisted 

 pedicels of the teleutospores. 



The uredospores of this species are especially interesting 

 because they belong to a class having a colorless wall, often 

 noticeably thickened at the apex, and roughened with minute 

 equidistant papillae, of which Puc. fraxinata is the best 

 known example. It is likely that the a?cidium when discov- 

 ered will be found to have spores with corresponding char- 

 acteristics.

Orig. Descr. II. Sori amphigenous, but mostly hypophyllous, soon 

 erumpent, surrounded by the ruptured epidermis, small (one-fifth to 

 one-half millimetre in diameter) oval or oblong, solitary. Uredospores 

 dull orange, globular, 20-25 micr. diameter, mostly 22 micr., always 

 free from pedicels when mature, covered with short sparse tubercles; 

 pedicels subpersistent, hyaline or slightly tinted, enlarged at tip, base 

 3-5 micr. in diameter, tip 5-8 micr. 



III. Sori amphigenous, small ( one-sixth to one-half millimetre in 

 diameter) mostly circular, solitary or rarely confluent, though often 

 abundant, teleutospores clear brown, slightly constricted at the middle 

 and often slightly thickened at the apex, subglobose, oval or oval- 

 oblong, 27-35 X 20-26, mostly 28-30 X 21-24, pedicel variable, taper- 

 ing, tinted, usually once to thrice as long as the spores."
