47396. Tripsacttm laxum Nash. Poacese. Guatemala grass. 



From Alta Vera Paz, Guatemala. Presented by Kensett Champney & Co., 

 Finca Sepacuite. Received May 2, 1919. 



" Introduced originally from Guatemala by Mr. G. N. Collins who states that 

 it grows wild rather extensively in the vicinity of Alta Vera Paz, Guatemala, 

 and is known to the natives as pal. No use is made of it by the natives. 



" Guatemala grass has grown very luxuriantly at Miami, Fla., for the past 

 three years. The canes become an inch or more in diameter and grow to a 

 height of about 12 feet. The nodes are numerous and the texture of the stems 

 rather soft and juicy with a somewhat mucilaginous sweetish sap. The leaves 

 are from 2 to 3 inches broad and are rather strongly armed on the margins 

 with minute sharp teeth. These teeth are the only objectionable feature to the 

 grass, as if carelessly handled the leaves will cut the hands. The grass looks 

 exceedingly promising for either silage or for green feed. At Miami canes are 

 often left over winter and have fallen down and become procumbent, and these 

 canes have produced flowers in abundance but no good seed. Therefore all dis- 

 tributions of the grass made thus far have of necessity been of pieces of the 

 cane, from which the grass grows very readily." (C. V. Piper.) 



An illustration of this grass as it grows at Miami, Fla., is shown in Plate I.
