may in many instances bear fruit (Fig. 154), or that fruit may 

 be borne at the end of last year's terminal growths, not spurs. 

 Hyslop, Mann, Missouri Pippin, Strawberry, Striped, Trans- 

 cendent and Winesap are among those varieties 

 producing fruit in the axils of leaves. Astra- 

 chan, Ben Davis, Grimes, Hyslop, Jonathan, 

 Mcintosh, Missouri Pippin, Newton, Northern 

 Spy are a few varieties found to be bearing fruit 

 on one-year-old spurs. A few varieties such as 

 Grimes, Hyslop, Transcendent, Willow Twig, 

 and Yellow Transparent produce fruit on the 

 end of last year's terminal growths, not spurs. 



Gourley has observed axillary fruit buds 

 throughout the Eastern States on both old and 

 young trees, and in many varieties. Different 

 forms of fruit branches occur; furthermore the 

 same variety, or even tree, may bear more than 

 one sort of fruit branch. Frequently, it has 

 been noted that spurs bear annually, instead 

 of biennially, as is the rule. In such a case, 

 fruit buds are developing on a spur at the same 

 time that an apple is maturing. 



It is not always an easy matter to distinguish 

 between the fruit and leaf buds of apple. 

 Generally, fruit buds are rather thick and 

 rounded, while leaf buds are smaller and more 

 pointed. 



It has been shown that fruit buds are differ- 

 entiated very early, and may be distinguished 

 by microscopic study, from leaf buds, as early as the last 

 week in June of the year preceding the opening of the flower. 

 The above has been reported by Drinkard, and Kraus has 

 observed that in the Yellow Newton apple, under Oregon
