VEGETATIVE SHOOT 



If the young part of a shoot be examined, it will be found 

 that in the angle between the upper face of each leaf and 

 the stem there is a bud (fig. 3 i). This angle is described as 

 the axil of the leaf. Thus we may say that a lateral bud* 

 arises on a stem in the axil of every leaf. These buds are the 

 beginnings of the lateral shoots or branches, and can develop 

 into shoots (fig. 3 ii.). We see, therefore, that lateral shoots 

 arise in the axils of leaves — in other words, the branching of the

shoot is axillary. A shoot possessing an unbranched stem is 

 described as simple (figs. 3, 4, the two left-hand drawings), but 

 when the stem is branched, the shoot is said to be compound 

 (figs. 3, 4, the right-hand drawing). 



Normal buds, then, are terminal or axillary. A bud does 

 not necessarily develop at once into a branch. It may 

 remain in a resting or dormant condition, and is then 

 described as a resting-bud, to distinguish it from an active 

 bud. 



' The bud appears as an external outgrowth of the stem ; it is exogenous.
