Dear Sir: 



The National Arboretum is attempting to locate as many 

 correctly named crabapple cultivars as possible, and 

 would appreciate your assistance in this undertaking. 

 To serve as a guide for this project, we are enclosing 

 a list of 375 cultivar names and their originators or 

 introducers . 



Will you please compare this list with your records, and 

 circle the name of each cultivar" now growing in your 

 collection that came directly from the indicated source. 



From your list, and those received from others, we plan 

 to compile, for further study, a master file of crabapple 

 cultivars and their locations . 



At a later date may we again request your assistance in 

 helping us document this material? 



Thank you for your' cooperation. 



Sincerely yours, 



^^-^~—
