This book is the result of a revision and elaboration of the author's 

 "Elementary Botany." The general plan of the parts on physiology and 

 general morphology remains unchanged. Considerable new matter b«s 

 been added, however, in the physiological part, especially on the subjects 

 of nutrition and digestion, and the subject of the morphology of fertiliza- 

 tion in the gymnosperms and angiosperms has been revised to bring this 

 abreast of the discoveries of the past few years. The greatest improve- 

 ment has been in the complete reorganization, rewriting, and elaboration 

 of the part dealing with ecology, which has been made possible by studies 

 of recent years, so that the subject can be presented in a more logical and 

 coherent form.
