same with the growth numbered one after it below the 

 branch. 



On the right of the pith, from C to DD, is the 

 growth of the stem while the branch was alive : and 

 five annual growths of the stem, both above and below 

 the branch, may be seen to be united to the five annual 

 growths of the branch ; namely, the first five annual 

 growths above the branch, and from the second to the 

 sixth inclusive below it. So that the first annual 

 growth of the branch is continuous and the same with 

 the first annual growth of the younger shoot of the stem 

 above the branch, but with the second annual growth 

 of the older shoot of the stem below the branch ; and 

 each annual growth of the branch is continuous and the 

 same with that growth of the stem above the branch 

 which corresponds with it in number, but with the 

 growth numbered one later below the branch. 



Here, then, it may be see?i that branches are 

 attached to the stem by increasing bases, not, as might 

 be imagined from De CandoUe s statement, by decreas- 

 ing bases ; that is, each annual growth of the branch 

 joins a corresponding annual growth of the stem, and 

 as each annual growth of the stem, besides the deposit 

 from the annual growth of the branch, receives a 

 deposit from the head above it, each annual growth of 

 the stem is larger than its corresponding annual growth 

 of the branch. The width of each annual growth of 

 the branch at the point of confluence, that is, where it 

 joins and mingles with the stem, may be seen to open
