ETTCALYPTUS PIPEEITA. 



The Eucalyptus-oil, so largely exported particularly by Mr. Joseph Bosisto since many years, 

 is not derived from this species, but from E. amygdalina. The vernacular name " Pej)permint- 

 tree " arose from this Eucalyptus, being bestowed on it already in the first year of the colonisation 

 of New South Wales by Dr. White, because the scent of the foliage resembling that of the 

 Peppermint-Herb ; but this colonial apf)ellation has become since extended to many other 

 congeners in various parts of Australia. This fancied resemblance of Eucalyptus-oil to that of 

 Peppermint is explanatory also of the specific name adopted for this particular tree in science. 

 Though timber of very large dimension is obtainable from E. piperita, yet according to the Eev. 

 Dr. WooUs the wood is inferior to that of some other kinds of Stringybark-trees. 



As stated under E. pilularis the fruit, depicted by White as that of his E. piperita, belongs 

 to the former not the latter, as now understood, although it is not pilular.
