A Text-Book of Botany for Colleges 



BY WILLIAM FRANCIS GANONG, 



Professor of Botany in Smith College 

 Part I, The Structures and Functions of Plants. Illustrated 



This work embodies the results of the author's well-known interest in 

 educational problems, and his long practical experience in botanical 

 teaching. It is intended for college students in the general or introduc- 

 tory courses in botany. While a clear exposition of the fundamental 

 facts of the science is the first aim, the effort is also made to keep prom- 

 inent the idea of interpretation or explanation of the principles of bo- 

 tanical phenomena, particularly those which are frequently met with. 

 The economic aspects of botany receive careful consideration in con- 

 junction with the scientific phenomena which respectively underlie 

 them. In order that the professor who is using the book may be enabled 

 to continue the type of laboratory work which he has found adapted to 

 his particular situation, the book is prepared in the form of semi-inde- 

 pendent sections, each of which deals with a leading topic. This method 

 of treatment will also make the book desirable for he general reader 

 who is interested in the subject of botany and who finds the prevailing 

 form of text inconvenient for reference.
