BUDS 



I. BUDS may be defined as incipient shoots. What does 

 this mean ? 



II. Examine a leafless branch of Beech, Birch, or Alder, 

 and notice the buds. 



1. There is a single terminal bud. 



2. The rest of the buds are lateral, i.e. situated upon the 



sides of the stem. 



3. The lateral buds are placed just above a leaf-scar, so 



that they occupy the vertex of the angle formed by 

 the junction of the leaf with the stem. This angle is 

 called the axil of the leaf and such buds are called 

 axillary buds. 



4. Sketch a portion of the branch so as to show both axil- 



lary and terminal buds ; and notice that the terminal 

 bud does not exceed the axillary buds very much in 

 size. 



III. Examine a leafless branch of Walnut or Butternut 

 and notice the buds. 



1. The terminal bud 'is larger than the lateral buds. 



2. There are several (2-4) buds above each leaf-scar. 



3. The one directly in the axil, i.e. nearest the leaf-scar, is 



usually very small. This is the axillary bud.
