4. The buds above it are larger. They are called accessory 

 buds (i.e. additional buds). They are also said to 

 be superposed (i.e. placed one above the other). 



5.. The Walnut and Butternut, therefore, have three kinds 

 of buds as classified by position: i, terminal buds ; 

 2, axillary buds, and 3, superposed accessory buds. 



IV. What difference does this make as regards the branch-

1. The large terminal bud. 



2. The upper lateral buds, in threes, above the leaf-scars. 



Distinguish 



3. The middle axillary bud. 



4. The accessory bud at each side. 



5. The accessory buds of the Maple, being arranged side 



by side with the axillary buds in a horizontal line, are 

 called collateral accessory buds. 



6. Make a sketch to show the collateral accessory buds. 



VI. Examine the terminal buds of the Buckeye or any 

 of those of the Currant. (They are in best condition for 

 this when just bursting open in the spring.) Notice : 



1. The overlapping brown scales which cover the bud. 



Buds with such coverings are called scaly buds. 



2. Pick off the scales one by one, beginning with the lowest, 



until well-developed leaves are reached, arrange 

 them, in order, in a row, and notice : 



3. That the inner scales are less brown, larger, and more 



of a greenish color.
