 ■patrick. Prof. C. E. Bessey in June, 1875, collected at Ames 

 what I take to be a late flowering form of this species, with 

 the strict leaves much exceeding the culm. The same form 

 in flower was collected by Prof. B. Shimek in Lyon county, 

 June, 1897. Both these may prove to be something else, but 

 further observations and more complete material are neces- 

 sary.
