8 AUTHOR'S PREFACE. 



Professor T. G. B. Osborn has permitted the use of the Tate and 

 Menzel-Cleland herbaria, which are stored in the University of 

 Adelaide; and Mr. J. F. Bailey has allowed me to consult the 

 Schomburgk herbarium in the museum of the Botanic Gardens. 

 These, together with my own collection, are the principal materials 

 examined for the production of the present work. 



The botanical drawings are by the author, with the exception of 

 those illustrating the Orchids, which are the work of Miss R. C. 

 Fiveash.
