Arthur : New species of Uredineae 



Jalisco, Mexico, October 5, 1903, Holway S JI S- The two col- 

 lections are apparently on different species of Reindict. This is a 

 peculiar form of rust. From the subcuticular pyenia, the unusu- 

 ally small aecia, and the strongly verrucose spores it is evident 

 that it does not belong under the Dicaeomatae, i. e., to any of the 

 usual forms of Pnccinia or Uromyces ; but its true affinities are not 



apparent.
