Even in many of the cases where all the buds appear 

 approximately equal in size, careful examination of strong 

 shoots usually shows that the terminal bud is the larger. 



But a further point arises in connection with the 

 terminal bud. In very many plants with the twigs end- 

 ing in a bud, close investigation shows two scars beneath 

 it, the characters of which enable us to say with certainty 

 that they are not both leaf-scars. The Lime affords an 

 excellent example. At the base of the bud, on one side 

 of the apex of the twig, there is a scar which marks 

 where the last leaf of the shoot was attached, and in 

 the autumn we find a leaf still there : immediately oppo- 

 site is a smaller scar, in place of which we find a bud 

 in the autumn, before the leaves have fallen. The ap- 

 parent terminal bud of the Lime-twig is therefore really 

 an axillary and therefore properly a lateral bud which 

 has usurped the place of the true terminal bud, the latter 

 having died off and left its scar. 



Such pseudo-terminal buds are very common. They 

 occur in 



Birch Lime As pen, 



Black Poplar White Poplar Hazel 



Elm s Willows ^ Hor nbeam 



Beech Oak s. 



When in the following year the pseudo-terminal bud 

 develops into a shoot, the latter continues practically
