EUCALYPTUS. 279 



The different and in some cases contradictory reports I 

 have seen on the Eucalyptus oils induced me to secure the 

 aid of S. M. Woodbridge, Ph. D., in making some ex- 

 aminations of these oils taken from species identified here. 

 I give the result of the doctor's work in his own words. 

 I also reproduce a recent article 03^ Prof. J. H. Maiden, 

 taken from the Chemist and Druggist of Australasia, March, 

 1895. Samples of the Eucalyptus oils made by Dr. Wood- 

 bridge, will be placed in the Los Angeles Chamber of Com- 

 merce. 



One of the results of Dr. Woodbridge 's distillations has 

 been to determine me in recognizing several species not 

 recognized by Baron Von Mueller. Where in addition to- 



bud, flower and fruit differences, as for instance, between 







Eucalyptus globulus and Eucalyptus Mortoniana, we have 

 oil derived from the foliage almost at the extremes of dif- 

 ference in the genus in yield and character, we may well 

 agree to recognize specific rank in each case. In other 

 species while the difference in the oils is not so great it is 

 still sufficiently marked to justify specific rank where now 

 only forms or varieties are recognized. It was the oil that 

 caused me to set up as a species Eucalyptus Californica 

 from what was before deemed a form of Eucatyptus occi- 

 dentalis. Eucalyptus Californica itself has two forms from 

 only one of which could I obtain leaves for distillation and 

 that the least attractive with a greenish yellow flower and 

 more drooping habit. The beautiful Eucalyptus Californica 

 with the crimson flower and so constantly in bloom at the 

 Santa Monica Forestry Station, we have in only one tree. 



Amongst the striking results of the Woodbridge distil- 

 lation we may note the following: 



Typical amygdalina gave 256.5 ozs. to the 1000 Ibs. of
