Adveutitious buds are commonly found emerging from the 



leptolepis, CHypto- 



trunk below the

Fi serotina. Were 



and mode of growth of main shoots. Sometimes, after injury by 



the pruniug-knife, or other cause by which the terminal bud is 



destroyed, lateral adventitious buds are formed which assume an 



erect direction. I have seen this in JPinu* Coulter*, P. excelsa ; 



Abies Regince-Amalia, 



a form of A. cephalonica, owes its origin probably to a like 

 cause *. 



Carriere describes and figures an example of this kind in Aran- 

 carta excelsa, in which the extremity of one of the side-branches 

 had been cut off, with the result that a new shoot was developed 

 near the cut end and which assumed an upward direction. But 

 this tendency towards the obliteration of lateral shoots as wit- 

 nessed in the sfi&ke-fir, or the proclivity on the part of lateral 

 shoots to assume the direction and form of erect shoots, is by no 

 means universal among Conifers. On the contrary, it is not un- 

 frequently a matter of regret to gardeners and foresters that 



# bifida, &c, do not de- 

 velop leader-shoots, or, if they do, the shoots die, either because 

 they are overpowered by the superior growth of the lateral 

 branches or from other causes. Tying up a lateral shoot so as to 



make

always, successful. 



So among the Cupressineae it frequently happens that lateral 

 shoots struck as cuttings, although they grow vertically, yet do 

 not assume the form of leading shoots, but retain the two-ranked 

 distribution of their leaves and their flattened form. But this
