 hand only from Big Sandy, July, 1892.

 Hatchery, July, 1891 ; Laramie River, June 22, 1895 (No. 1317).

 Blench Grass. 

 Poa Vaseyana, Scribn. 



This fine sp'. cies was found in abundance by Prof. Buffum, on 

 the Big Sandy, July 1892. He sent it for determination to Dr. 

 Beal, who pronounced it probably new. Whether specimens were 

 later sent to the Department of Agriculture or the same had been 

 collected by Dr. Vasey I am unable to say, but subsequently it re- 

 ceived the above name. 



Poa sp. 



Of this. Dr. F. Lamson-Scfibner writes : " I am not prepared to 



name it. It has some characters in common with Poa occidentalis, 

 Vasey, but it is apparently distinct from that." 

 Glyceria arundinacea, Kunth. 



On Spring Creek, Big Horn Mountains, August 5, 1892.
