280 R. T. BAKER AND HENRY G. SMITH. 



" The fruits of E. laevopinea, R. T. Baker, from Gulf Road, 

 Rylstone (R. T. Baker) display such variation in size and shape 

 as to have caused differences of views as to the species. For 

 example, in Proc. Linn. Soc, N.S.W., 1896, Mr. Deane and I 

 referred some of them to an abnormal form of E. macrorhyncha 

 between it and E. capitellata. That they are identical with E. 

 Mulleriana, Howitt, has since been shown " 



Under E. macrorhyncha in the same work no reference 

 is made to E. laevopinea. 



Remarks. — Prom the above it will be seen that on 

 morphological grounds considerable differences of opinion 

 have arisen in regard to this species. Since it was described 

 in 1898, however, further material of this Eucalyptus has 

 been examined from trees growing far north of the original 

 locality of Rylstone, and so far no new facts have been 

 brought to light that would warrant its being described as 

 other than that it is specifically distinct from any of its 

 congeners. To place it under E. pilularis or E. macro- 

 rhyncha, with their chemical characteristics, would be fatal 

 to the commercial exploitation of E. laevopinea and E t 

 dextropinea for their respective turpentine oils. 



With the price of turpentine now ruling, manufacturers 

 will necessarily look to other fields for supplies. The " Oil 

 and Colour Trades Journal," August 26th, says: — 'Accord- 

 ing to Bulletin 40 of the United States Agricultural Depart- 

 ment, the supply of turpentine in the United States will be 

 exhausted in 1918. While the sources of supply have been 

 decreasing, statistics show the demand has increased over 

 90 per cent, in the last 15 years.' 



This question is therefore of some importance to Aus- 

 tralia, as it would be possible to procure early supplies of 

 turpentine from young plants of pinene yielding Eucalypts 

 grown from seed. The leaves of the young growth of 

 eucalyptus species yield oils identical in composition with
