CHAPTER V. 



POSITION AND ARRANGEMENT OF BUDS continued. 



Number of buds on shoot Leaf-axils devoid of buds Accessory 

 buds Superposed and collateral buds Dormant buds Epi- 

 cormic shoots Suckers Adventitious buds Angle of in- 

 sertion. 



IT will be seen from the foregoing that the number of 

 lateral buds on a shoot just emerged from the winter 

 rest in the winter bud is limited, because the number of 

 leaves contained in such a bud is limited ; though the fact 

 must not be overlooked, that additions to the numbers 

 may be made subsequently by outgrowths at the apex. 

 This limit of the number of buds may vary considerably 

 in different cases, and this depends on two principal 

 classes of events. 



The rule is that each perfect leaf forms a bud in its 

 axil i.e. in the angle formed by the upper surface of 

 the leaf with the shoot bearing it ; and that no buds are 

 formed in the axils of the true bud-scales. But the rule 

 has many exceptions. In the Birch, Hornbeam, Beech, 

 Lime and some others, no buds are developed in the 

 axils of the lowermost couple of leaves: buds also are 

 commonly wanting in the axils of the crowded leaves of 

 dwarf-shoots, e.g. Pine, Larch, Cedar, Beech, Alder, &c., 

 and in Conifers generally buds which will give rise to
