and recommends it for Arizona. Xcav Mexico, and the pinelunds of 

 Florida. His hedge plant {CoJeus harbatus, No. 51239), producing 

 masses of slc^^-blue flowers, will be a desirable novelty if it proves 

 hardy. 



O. F. Cook has pointed out that we have in the driest desert 

 region of California a leguminous tree {Olneya tesota^ No. 51254), 

 the beans of which when roasted resemble peanuts. These Olneya 

 trees, as they are called, are among the most attractive trees of our 

 Southwest. They deserve trial in other desert regions of the world. 



The iburu {DigitaHa ihurua^ No. 51257), a cereal grown by the 

 natives of Northern Nigeria and producing a small, pure-white grain, 

 is already under observation by Mr. Piper, who considers it worth 

 while from the standpoint of a forage crop. 



Perhaps the macui {Solanum sp.. No. 51265) which Mr. Johnson 

 finds in use among the Kekchi Indians of Alta'Vera Paz, Guatemala, 

 may be what we are looking for as a summer green vegetable for the 

 South. He says th^ tender 3'oung tips are widely used and have an 

 excellent flavor. 



The fufu grass {Pennisetum furpureum^ No. 51286), of Rhodesia, 

 IS found by Mr. Holland, of Port Elizabeth, South Africa, to be 

 softer, sweeter, and more succulent than Napier grass, and this for- 

 age crop may prove superior to the latter in our Southern States. 



The botanical determinations of seeds introduced have been made 

 and the botanical nomenclature revised by H. C. Skeels, and the de- 

 scriptive and botanical notes have been arranged by G. P. Van 

 Eseltine, who has had general supervision of this inventory. The 

 manuscript of this inventory has been prepared by Miss Esther 

 A. Celander and Miss Patty T. Newbold.
