﻿52 SEEDS AND PLANTS IMPORTED. 



47330 to 47348. Castanea dentata (Marsh.) Borkh. Fagacea?. 



Chestnut. 



From New York. Scions collected by Dr. Walter Van Fleet. Received 

 March 29, 1919. 



"The material consists of grafting wood collected from trees that show 

 evidence of resistance to infections of Endothia parasitica which has existed for 

 nearly 20 years and has nearly destroyed all of the very abundant stands of 

 chestnuts about the city of New York except three scattered groups. These were 

 discovered during the past summer by Dr. A. H. Graves, New Haven, Conn., 

 and the trees were numbered by him from 1 to 142. These groups are so dis- 

 posed that it is conceivable that they may each be descended from a naturally 

 resistant ancestor in each locality. Numbers 1 to 48 are situated in Innwood 

 and Van Cortlandt Parks, at the north end of Manhattan Island, Nos. 49 to 76 

 near Hollis, Long Island, and Nos. 77 to 153 near Valley Stream, Long Island, 

 all within a few miles of New York City. Material was collected only from the 

 most promising trees in each locality." (Van Fleet.)
