Z PLANT MATERIAL INTRODUCED 



It should be noted again that this inventory does not represent material now in 

 the Office of Foreign Plant Introduction. Much of it has been turned over to 

 other offices, and some of it, at least, will be removed from propagation until it 

 has been tested to determine its value in this country. 



The botanical determinations have been made and the nomenclature deter- 

 mined by H. C. Skeels, who has had general supervision of this inventory.

 Principal Horticulturist, in Charge.
