(Silvia officinalis), Lilac (Syringa vulgaris), and the well-known 
Iris, will suffice to prove the mutual connection of the young 
leaves in certain vegetables, while they are yet shut up in 
the bud. 
In most trees of temperate regions the buds make their appear- 
ance in spring, stopping at an early stage of their development, and 
only elongating themselves in the following spring. They ramify 
slowly, and it is only once a year that branches are produced. 
Nevertheless, in the case of the Peach-tree and the Vine, two 
generations of branches are produced. The cause of this is, that 
their scaly buds have remained stationary during the autumn and 
winter of the preceding year, have elongated themselves in the 
spring and given birth at the axils of their leaves to buds, which 
in place of remaining stationary, and developing themselves only 
at the commencement of the approaching season, grow without 
interruption, and produce new branches. French horticulturists 
have given the name of prompt-buds to these shoots. Branches 
which, on the other hand, only carry scale buds, and develop them- 
selves the year after, are called dormant buds. 
We have spoken of normal buds, which are borne on the axils 
of the leaves, or which terminate the axis. There are others which 
present themselves without any order, and the exact spot where 
they present themselves cannot be foreseen. These are adventitious
