 I'oa horrale, Hook., Fl. II., 245. 



We place all our interior specimens under the variety, as they have 

 the loose panicle, few erect spikelets and pale green color that 

 characterize it. Very abundant by salt marshes throughout the whole 

 prairie region, from Winnipeg westward to the mountains, and the dry 

 interior of British Columbia. Hand Hills, and Eed Deer Lakes, 

 Alberta. (Macoun.) Maple Creek, Alberta. (J. M. Macoun.) Thompson

721. DACTYLIS, Linn. Gen. 86. (ORCHARD GRASS.) 



(2845.) D. GLOMERATA, Linn. ; Nees. Gen. t. 65. 



Cultivated in orchards and lawns, and escaped to roadsides in many 

 parts of the older provinces. It seems better suited for Vancouver 

 Island than timothy, as it produces better fiasture.
