CHAPTER IX 



SUMMARY 



The Bud 



The bud is a young shoot that is, a stem or branch 

 with its rudimentary leaves closely packed together. 

 It is normally situated either at the summit of the stem 

 or in the axil of a leaf. 



The young leaves require protection against too 

 great cold, heat, drought, or moisture, too vivid light, 

 and the attacks of animals and plants. This is effected 

 in various ways. 



The scales which protect the winter-buds fall into 

 at least eight categories : 



1. Pedestals of last year's leaves, as in Pyras Aria. 



2. Stipules of last year's leaves, as in Magnolia. 



3. In many cases the young leaves are protected 

 by modified leaves, as, for instance, in Willows and 

 Lilac. 



4. In others the protection is afforded by leaf-stalks, 

 the leaf not being developed, as in Maples and the 

 Sycamore ;
