Poa Tracy l. 



A species of Poa, which was found abundant near some springs 

 toward the top of the mesa. 

 Scliedonnardus Texanus (Grab-grass). 



Common on the vegas and valued for early pasture, but worth- 

 less for hay or late range. Found through New Mexico and 

 Arizona. 

 Oarex muricataf (Water-grass). 



Very abundant on the side of the mesa and in low places on the 

 top. It is cut with the grasses for hay and is eaten fairly well. 



Santa Fe, New Mexico, June 13. 



The grasses of the mesa in this vicinity are very sparse, chiefly con- 

 sisting of Grama (Bonteloua oligostacliya) and Buffalo grass (Bucliloe 

 dactyloides). In the mountain valleys and hill-sides there is a larger va- 

 riety. On irrigated land some of the eastern species occur.
