Introductory. My examination of Australian tropical 

 Acacias* has gradually led to an investigation of those of 

 tropical Queensland. I have found that their taxonomy 

 was in a very unsatisfactory state, and one of the results 

 of my work has been to indicate certain lines of investi- 

 gation. As regards Queensland we can build on the found- 

 ations laid by Cunningham, Bentham, Mueller, Bailey and 

 Cambage, but the following pages show some of the many 

 hiatuses there are at present in our knowledge. 



Tropical Queensland is not a botanical province, but I 

 speak from experience when I say that the possession of a 

 ist of the species in that area Avill be a public convenience.
