CLASS XX. 
GYN4NDRIA. 
In this class the stamens are inserted either upon 
the style or germen. Linnaeus divided the class into 
nine orders, the character of which is taken from the 
number of stamens ; but succeeding botanists have abo- 
lished some of these orders, and some have abolished 
the whole class, and referred the plants included under 
It to other classes. Without going over the whole of 
the orders, a few examples will be sufficient to illustrate 
the class.
