Introduction.— The ground covered by this paper includes 

 botanical remarks, descriptions, chemistry of the oils and 

 general economics of the following species of Eucalyptus: 



E. acaciaeformis, Deane and Maiden. 



E. Andrewsi, J. H. Maiden. 



E. Bridgesiana, R. T. Baker. 



E. laevopinea, R. T. Baker. 



E. nova-anglica, Deane and Maiden. 



E. campanulata, sp. nov. 



New England might be called the land of the " Pepper- 

 mints," for in no other part of New South Wales is the 

 term "peppermint" applied to so many Eucalypts in such 

 an indiscriminate manner, and one might add without 

 sufficient reason, for many of the trees so called do not 

 contain the peppermint constituent, piperitone, in their oil. 

 What has been the ruling feature in such naming is, how- 

 ever, not far to seek. The designation has most probably 

 been applied originally, and since passed on, to the nature 

 of the bark, for it resembles in its general features the 

 characteristics of the Sydney Peppermint, E. piperita, to 

 which species of Eucalyptus the name peppermint, owing 

 to the presence of the peppermint constituent, was applied 

 by the medical officers of the First Fleet in 1788, and con- 

 sequently this is regarded as the type of all peppermint 

 barks.
