Tripsacum dactyloides, Linne. 



Central and North America ; known vernacularly as Gama Grass. 

 A reedy perennial grass, more ornamental than utilitarian. It is 

 the original Buffalo Grass, and attains a height of 7 feet, assuming 

 the aspect of maize. It is of inferior value for fodder, but serves 

 for binding sand. C. Mohr however regards it as a valuable fodder-

 in Southern Bolivia. 



Triticum junceum, Linne. 



Europe and North Africa. A rigid grass with pungent leaves and
