SOME PLANT RELATIVES 
in a hard pit at their centers. The raspberries, dewberries, 
and blackberries are made of tiny stone fruits arranged in 
close clusters. 
The members of each of these groups are, of course, 
closer kin to one another than they are to members of 
the other groups. The apple and the pear might be set 
down as first cousins. The peach and the cherry are first 
cousins. The blackberry and the raspberry bear the same 
relationship to each other. 
The next step of relationship might be considered that 
of brother and sister. Take, for example, a group like the 
cherries. In that group are found the sweet cherry trees, 
which grow tall and yield the fruit that is so good to eat 
right out of the box. Then there are the sour cherries. 
They grow on low, bushy trees and are not so good to eat, 
but are better for canning and for pies. The relationship 
between them is much like that of brother and sister.
