IDENTIFICATION OF PLUM VARIETIES 9 



The size of individual leaves is often influenced materially by the vigor of 

 growth of a tree. Nevertheless, leaf size differences are quite dependable be- 

 tween varieties. Average size of the blade varies from small in Shropshire and 

 American Mirabelle to large in Field and Washington. 



Leaf shape may be roundish as in Monarch, oval as in Hall and the majority 

 of varieties, obovate as in Italian, long-obovate as in Burbank, elliptic as in 

 Red June, or narrow elliptic as in W'ickson (Figure 4).
