The only previous report of this species known to the writer 

 is that in the Metaspermae of the Minnesota valley. This was 

 based upon a specimen now in the Minnesota State Herbarium, 

 collected in Blue Earth county, Minn. {J. B. Leiberg, 1883). It 

 was found also on the sandy shores of lake Lida, Otter Tail 

 county, Minn. (E. P. S., Aug., 1892).

This species was collected at St. Anthony Park, Ramsey 

 county, Minn. (Z>?\ Otto Lugger, Sept., 1893). The plant is 

 probably of recent introduction, but is now becoming thor-
