 tised as containing "descriptions" of so many 

 thousand species; but they are "sair" reading 

 for beginners, who depend so much upon pic- 

 tures for identifying their plants, and who

 for the amateur, such a book would not be at 

 all desirable. It would be so huge, and so dif- 

 ficult and clumsy to use.
