I have also consulted frequently: — 
“Orchids” by Watson & Bean. 
“Orchids” by Jas. O’Brien. 
“Orchids” by Watson & Chapman. 
“Orchid Growers’ Manual” by Williams. 
““Orchideae” by Lindley. 
“‘Dendrobiae Monandrae” by Kraenzlin. 
“Manual of Orchidaceous Plants” by Veitch. 
“Queensland Flora” by F. Manson Bailey. 
“Encyclopaedia of Plants” by J. Loudin. 
“Flora Australiensis’” by G. Bentham and F. Meuller. 
Also many articles in the Australian Orchid Review, Orchidologia Zeylanica, — 
the Orchid Review, etc. 
The information on climatic conditions has been garnered from reports by 
meteorological officers in many parts of the world. I have also had recourse to 
“An Introduction to the Study of Climate’ by Trewortha, “World Weather” 
by Clayton, ‘A Study of Climates” by Koppen, and “‘Reseau Mondial,” a com- 
pilation of weather data and statistics from all observation stations in the world. 
I should also like to express here my thanks to Mr. C. T. White, Queensland 
Government Botanist, Mr. W. D. Francis, Acting Government Botanist, and Mr. 
A. S. Richards, the Commonwealth Meteorologist, for their assistance and advice. 
I should also be lacking in courtesy and gratitude if I omitted to record my thanks 
to Miss Alice Hart, who has so carefully typed out the manuscript for this work, 
this being a particularly onerous task in view, not only of the unfamiliar botanical 
names and terms, but also because of the almost indecipherable character of my 
writing. Thanks are due, also, to Miss R. W. Barr, who has done much valuable 
work in proof-reading and checking manuscript on the book.
