NOTES ON GRASSES OF NEBRASKA, SOUTH 

 DAKOTA AND WYOMING. 



BY L. H. PAMMEL. 



In two former papers the writer* has discussed the grasses of Colo- 

 rado and Nebraska. In this paper I shall enumerate the grasses col- 

 lected during the season of 1897. The grasses of Wyoming have been 

 discussed in a general way by Tweedy,** F. Lamson-Scribner, and 

 Frank Tweedy,*** Parry,*! Nelson,*!! Forwood,**! and Greene.***! 



The forage conditions of the state have been discussed more espe- 

 cially by Williamsf for Northern and Northeastern Wyoming, and the 

 Red Desert Region of Southern Wyoming by Nelson. ;[ 



The writer desires to acknowledge the assistance rendered him by 

 Prof. F. Lamson-Scribner who kindly looked over the grasses collected 

 on the trip.
