The number of classes as arranged by Linnaeus, was twenty, 

 four. Two of them, Poly-delphia, (many brotherhoods,) 

 which was the eighteenth class ; and Poly-gamia, (many unions,) 

 the twenty -third class, have, by late botanists, been rejected as 

 unnecessary. 



The eleventh class, Dodecandria, which included plants 

 whose flowers contain from twelve to twenty stamens, has been 

 more recently omitted. The plants which belong to these have 

 been distributed among the other classes. 



A few botanists retain the whole twenty-four ; among Ame- 

 rican writers who adopt but twenty-one, are Eaton, Torrey, and 

 Nuttall.
