been entertained respecting the im- 
portance of the pith ; Linnaeus con- 
sidered it was the seat of life and 
source of vegetation ; that its vig- 
our was the principal cause of the 
shooting forth of branches, and that 
the seeds were formed from it. It is 
now generally thought that the pith 
does not perform so important a part 
in the economy of vegetation as 
was supposed by Linnteus.
