POLYGAMIA. 
Class XXII I. 
Class XXIII. — POLYGAMIA. 
Flowers either male, female, or hermaphrodite, upon the same or different plants. 
This class differs from the two preceding in having not only the sexes in different flowers upon the same in- 
dividual as in Monoecia, or upon separate individuals as in Dioecia, but also combined in one flower, mixed 
among those which are unisexual. It may, therefore, be considered to contain those genera which are in a 
state of transition from the common hermaphrodite structure to absolute unisexuality. 
To the first of its orders are referred several grasses, which are excluded from the early classes on account 
of the separation of their sexes ; it also contains the numerous tribe of Mimosas, so well known for their 
various properties as objects of food, of ornament, of medicine, or of curiosity. The maple is also stationed 
in the first class, as are a few genera of palms. 
The most important genera of the second class, besides the poetical Palmetto, are the ash and the fig. 
Gleditschia and Ceratonia, two families of Leguminosse, are valuable, the former for its light, airy, elegant 
foliage, and the latter for its sweet pods, which are used in Spain, in great quantities, as fodder for cattle.
