Young trees purchased from the nursery generally have a label fastened

bark as the stem grows and interfere with its work and often kill the
top of the tree or injure a main branch.

These are a few ways in which the work of the stem is sometimes
checked and the plant injured thereby.




CHAPTER XV

FLOWERS


In our study of the parts of plants the flower and fruit have been
given the last place because in the growing of most farm plants a
knowledge of the functions of the flower is of less importance than
that of the roots, leaves and stems. However, a knowledge of these
parts is necessary for successful fruit culture and some other
horticultural industries.

As with the other parts of the plant our study will not be exhaustive
but will be simply an attempt to bring out one or two important truths
of value to most farmers.

In the study of flowers the specimens used for study will depend upon
the time of the year in which the studies are made and need not
