* For origin of the names of the genera, both classical and English, and the 

 essential and natural generic characters, the reader is referred to Doctor Thornton's 

 Practical Botany, being a New Illustration of the Genera of Plants ; with a Descrip- 

 tion, and Plates of Dissections of each Genus. This book will be found a useful 

 introduction to that work. 



The reader is also referred to another work, entitled The Botanists' Vade Mecum j 

 where all the essential generic characters are given by themselves ; a most useful 

 pocket-companion to the botanist.
