PLATE XLIX. 



A TYPICAL PEPPERMINT BARK. 



Eucalyptus Australiana, R.T.B. & H.G.S. 



These barks might be described as a fine lattice pattern, and rather closer in texture 

 than those of the " Stringy barks," but shorter in the fibre, and the colour more bordering 



on that of the " Boxes." 



The chief constituents in the oils of Eucalypts with bark of this character are cineol, 



phellandrene and piperitone. These constituents vary in amount in the several species. 



The " Peppermints " apparently represent the later species of the genus.
