 It is possible, that under conditions more dry than

 of further investigation. 



Blue Grama (Bouteloua oligostacliya). — This grass 

 belongs to a somewhat numerous family, which have 

 special adaptation for warm, dry range conditions. It 

 has also been called Mesquit of Mezquite. It is the 

 most promising of all the grama grasses, although the 

 variety Tall Grama (Bouteloua racemosa) has been" 

 well spoken of. Blue grama grows to the height of 

 6 to 18 inches, but seldom exceeds the height of 12 

 inches, under range conditions; under cultivation it 

 grows higher. The leaves are numerous, narrow and 

 firm. The spike is 1 to 5 inches long. It has strong 

 rhizomes and forms a dense turf. 



It is a hardy grass and specially drought resistant. 

 It is much relished by live stock as pasture or as hay.

 It grows at its best bet\yeen latitudes 36 deg. and 42
