PREFACE xi 



of systematic botany and morphology, and to the expert 

 study of Forest-Botany. Nor shall I avoid sections on 

 Histology and Physiology when they come legitimately 

 within the scope of the scheme, so that the latter may 

 be shortly expressed as an attempt to teach the funda- 

 mental principles of Botany by means of examples selected 

 from trees and other woody plants. 



Succeeding volumes are designed to deal with the 

 Leaves, Inflorescence and Flowers, Fruits and Seeds, 

 Seedlings, and the Habit and Conformation of the Tree 

 as a whole, in a similar way, in each case with diagnostic 

 tables at the end to be devised for use in the field. 



The illustrations of twigs in the present volume are 

 to so large an extent due to the skilful drawing of 

 Miss Dawson, of the County School, Cambridge, that 

 I wish to express my special thanks to her for the 

 trouble she has taken : her drawings are marked (D). 

 In addition to these, other drawings have been obtained, 

 by the courtesy of the various publishing firms concerned, 

 and are marked as follows : (F) Figuier ; (E and P) 

 Engler and Prantl ; (Wo) Wossidlo ; (Wi) Willkomm ; 

 (Sc) Schwartz ; (Ha) R. Hartig ; (He) Henry, Knospen- 

 bilder 1846; (K) Kerner; (V) Veitch ; (Sa) Sachs; 

 <(Ei) Eichler. Other illustrations are from my own 

 drawings. 



Thanks are also due to my wife for preparing the 

 index and reading through the proofs.
