(138.) Linneean Classes. The first eleven classes 

 are characterised by the " number" merely, of the 

 stamens, which the species (or nearly all of them) in 

 the respective genera contain ; and their names are a 

 compound of two Greek words, one of which signifies 

 that number, and the other is avip (a man). The 

 number eleven is not employed, as no flowers are found 

 to possess that number of stamens. In the first ten 

 classes, the species are pretty constant in the num- 

 ber of stamens by which their class is designated 

 but in the eleventh class the number is not so certainly 

 fixed. There are, however, very few species included 

 in it ; and when the genera to which they belong have 

 been once pointed out, the student is not afterward < 

 likely to refer them to 

 another class. 



Although the name of 

 the twelfth class would 

 indicate that the species 

 referred to it contained 

 twenty stamens, whilst ' 

 those of the thirteenth 

 contained more than that 

 number, the real dis- 

 tinction between these 

 two classes depends more upon the position, than 

 upon the number of these organs. In both classes 

 the stamens are numerous that is to say, are above a 

 dozen in number ; but in Icosandria they adhere to the
