4 PREFACE. 



It is suggested to teachers using this book that they shoukl 

 take pains to secure for class-room study only such plants as 

 are described in the manual, that time may not be wasted and 

 pupils discouraged by efforts to identify species which are 

 too difficult for elementary work. The illustrations are from 

 Bergen's text-book, and are used with the original numbers. 

 In preparing the descriptions living plants have been exam- 

 ined whenever possible, while free use has been made of 

 Chapman's Flora of the Southern States, Gray's Synoptical 

 Flora, Britton and Brown's Illustrated Flora, and other 

 botanical works.
