of the bud to the branch, and another from the b

I 



There is another reafon, why the lateral buds of many plants pro 

 duce flowers fooner than the fummit; which is, that the lateral bud 

 of thofe plants, where the pith of the upright central flioot 

 divided, are propagated from the central (hoot, and are thereforc one 



ir • and have thus acquired the maturity neceffary for

In other plants, where the pith of the ftem 



o 



divided at every joint, the fummit bud has been preceded by more 



d is therefore more mature for the purpofe of produc-
