Journal of the Linnean Society; American Journal of Botany ; Botanical 

 Gazette; Journal of the Torrey Botanical Club; Journal of Agricultural 

 Research; Biological Bulletin; Growth; Lloydia; Flora, Biologische 

 Zentralblatt ; Botanische Zeitschrift; Revue Generale de Botanique; 

 Phytomorphology ; Transactions of the New Zealand Institute; Pro- 

 ceedings of the Linnean Society of New South Wales; and to others with 

 whom the author has been unable to make contact. The author is also 

 much indebted to Mr E. Ashby and Mr P. Dawes for assistance in the 

 reproduction of illustrations and to Mrs M. Lightfoot for secretarial 

 assistance. Dr A. Allsopp and Dr M. G. Calder have been so kind as 

 to read some of the chapters and have given the author valuable 

 criticisms for which he now expresses his gratitude; but the responsi- 

 bility for the text is his own. Lastly, he is deeply indebted to his 

 publishers, Messrs Methuen & Co. Ltd for all the assistance they have 

 given in the production of this book.
