Having thus given an introductory table of the divisions of the 
sexual system for a reference, I shall now proceed to explain the 
meaning of the terms used for the titles of the classes and orders, and 
at the same time informing the young botanist how they may be dis¬ 
tinguished from each other. As the terms used are all in the Greek lan¬ 
guage, from whencefhey are taken, they are all expressive of the prin¬ 
cipal circumstance that obtains in the class to which they are applied, 
the explanation of them will, of itself, give us a good insight into the 
proper characters of the several classes, and the sexual distinctions on 
which they are founded. 
Classis I.— Monandria. 
Monandria , from monos , one, and aner , a man. 
The word here compounded signifies a husband ; 
so that this class bears bisexual flowers, furnished 
with one husband, i. e. one stamen, or male organ 
for generation. 
This class, which is not large, contains chiefly 
exotic plants; and of these the tribe of Scitaminece 
is considered one of the most beautiful families of the vegetable kingdom. 
The useful productions are chiefly the ginger, cardamon, and turmerick, 
spices highly esteemed, and in general use wherever they are known 
and can be procured. The Salicornia, a native of our own shores, 
is burned for kelp, and pickled for culinary purposes. Almost all the 
plants of this class are aquatics, or grow in marshes. Orders two, viz. 
Monogynia , derived from monos, one, and gyne, a woman ; flowers 
of one style ; Canna Indica. 
Digynia, dis, twice, gyne, a woman ; flowers furnished with two 
styles; Blitum capitatvm.
