EXPLANATION OF FIGURES 



Outline drawings of terminal branches from the common privet. 



Fig. 1 .\ branch in which the terminal bud is in a resting state. The common 

 condition following a limited period of growth. 



Fig. 2 A new shoot grows from the apical bud, all of the axillary buds at the 

 base of the leaves remaining in a resting state. This is the usual manner of 

 resuming growth. 



Fig. 3 An unusual case in which two shoots grow out after the resting period, 

 the usual one from the apical bud and the .second one from the upper right axil- 

 lary bud. The potential impulse to grow on the part of the axillary bud was as 

 great as that of the apical bud and twins developed from the two potential growth 

 l)oints. 



Fig. 4 The very rare case in which not only the apical bud grows into a 

 shoot, but shoots also grow from both upper axillary buds. Here all of the 

 upper potential growth points produce individual shoots, and 'triplet' branches 

 arise.
