32 ILLUSTRATIONS OF THE 



FIRST CLASS.— MoNANDRiA. 

 Stamen 1. Flowers united. Orders 2. 



This class is but of small extent, having only- 

 two orders, Monogynia and Dyginia. 



For the sake of more accurate arrangement, 

 and readier reference, the several orders have been 

 formed into subdivisions, according to certain cha- 

 racters in the fructification. 



The order Monogynia, in this class, has two 

 subdivisions, namely, Gymnospermia, seeds naked, 

 and A?igiospermia, seeds contained in a capsule. 

 Samphire (Salicornia) and Mare's-tail, (Hippuris) 

 are of the first subdivision ; Chara of the second. 

 Of the order Digynia, only one example has been 

 discovered in Britain, viz. Star-wort, (Callitriche.)
