POSITION AND ARRANGEMENT OF BJJDQ continued. 



Number of buds ou 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 var}^ 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 Avhich will give rise to
