Scveral grasses have been tried at the United States Agricultural Experi- 

 ment Station, Honolulu. .Indropogoti nodosus, A. scricciis, and A. saccharoides 

 are promising. In the vicinity of the station these grasses have shown their adapt- 

 ability by escaping from cultivation. 



Sudan grass, a kind of sorghum, has been tried and has shown its adajna- 

 bility. An excellent field of Sudan grass grown for hay was seen at the United 

 States Agricultural Substation at Maiku (PI. XXXIII, './). 



INTKOnrCKI) SPECIES OF GRASSES. 



A large proportion of the grasses of the Islands have been introduced from 

 other countries, mostly from Europe, a few from Australia and the East Indies. 

 The native species are of special interest because of the unusual isolation of the 

 islands. Many species are endemic, and most of the others have extended north- 

 ward to Hawaii from the East Indies and the southern Polynesian islands. 



The following species appear to be introduced, some being well established, 

 others being recent escapes from cultivation or mere waifs. Those with an 

 asterisk [*] were probably introduced for trial as forage or lawn grasses and have 

 escaped from cultivation. Perennial s])ecies are followed by P.
