SOME NEW ENGLAND EUCALYPTS AND THEIR ECONOMICS. 273 



a — + 40*4 or specific rotation [a] D = + 46*74°; of the 

 second fraction a n = + 35'5°. The refractive index at 

 21° C. of the first portion = 1*4661; of the second =1*4686. 



The residue gave S.N. 80*6 or 28*2 per cent, of ester, 

 calculated as geranyl acetate. The acid of the ester was 

 isolated and determined to be acetic. The saponified oil 

 had a marked odour of geraniol, but it was too small in 

 amount to enable the alcohol to be separated. All the 

 evidence, however, goes to show that the ester of this oil 

 is almost entirely geranyl acetate. 



Eucalyptus Andrewsi, J. H. Maiden. 

 "New England Peppermint." 

 Historical. — According to Mr. Maiden the specimens 

 collected by Mr. W. Christie in 1877 in connection with his 

 paper on*" The Forest Vegetation of Central and Northern 

 New England in connection with Geological Influences," 

 Proc. Roy. Soc. N.S.W., 1887, belong to this species. 



Messrs. Deane and Maiden describe it in the Proc. Linn. 

 Soc. N.S.W., 1898, p. 794, under the name of E. Sieberiana 

 var. Oxleyensis. 



It was however raised to specific rank in 1904 by Mr. 

 J. H. Maiden, Proc. Linn. Soc. N.S.W., and is more fully 

 dealt with by this author in his "Critical Revision of the 

 Genus Eucalyptus," Part VII. (Vide note under remarks 

 in this paper as to systematic position of this Eucalypt). 



Remarks. — Like most other Eucalypts this tree unfortu- 

 nately has several vernacular names, being known as 

 ''Blackbutt," "Peppermint," and "Messmate," but these 

 are not mentioned here to be perpetuated, but the reverse, 

 and the hope is expressed that the name of New England 

 "Peppermint" will in future be associated with it. 



This common name now carries an important commercial 

 significance from its association with phellandrene in the 



R— Nov .1, 1911.
