SPECIAL ACKNOWLEDGMENT. 
The author desires to express his especial thanks and 
appreciation of the careful editing by Mr. P. A. Gilbert. 
When the work was commenced it was intended merely 
for circulation among the enthusiastic members of The 
Queensland Orchid Society, many of whom had no par- 
ticular interest in the actual scientific classification and 
nomenclature of their plants. I therefore referred to 
to several species by the names by which they are generally 
known to orchid growers. For the wider purposes of this 
edition it was desirable that a more accurate classification 
be made, and I am deeply grateful to Mr. Gilbert for his 
valuable assistance in this and also for revising the notes on 
the distribution of Australian orchids.
