2 8o EUCALYPTUS. 



leaves. Eucalyptus amygdalina, var. regnans, gave 180.5 

 ozs., while the var. angustifolia gave but 148.7. The oil 

 from the first was a clear yellow, while the other two were 

 green but of different shades. While all these bear a dis- 

 tinctive pepperminty-Eucalyptus odor and taste they were 

 markedly different from each other in intensity. The 

 specific gravity of the first oil was at the extreme end of 

 the line in lightness from that of the other two. Besides 

 the three forms of amygdalina examined we have here two 

 others quite as distinct in appearance. I have no doubt 

 that the botanic individuality of several forms of amygda- 

 lina should be given specific rank if only from the deep- 

 seated difference shown to exist by their oils. 



Eucalyptus sideroxylon, var. pallida, contains 181.36 oz. 

 of oil. Eucalyptus sideroxylon, with green foliage and 

 white flowers, contains 146.6 oz., and is next to Eucalyptus 

 Stuartiana, the heaviest of the Eucalyptus oils examined. 

 Eucalyptus leucoxylon, formerly taking in Eucalyp- 

 tus sideroxylon as a form, contains but 33.3 oz. of oil. 

 Eucalyptus globulus contains 134.8 oz., and Eucalyptus 

 Mortoniana, suggested to be a form of Eucalyptus globulus, 

 contains but 10.90 oz. 



The oils from Eucalyptus rostrata and Eucalyptus tereti- 

 cornis appear to be as similar in character as they are in 

 yield. This is in flat contradiction to the position of 

 Schimmel & Co., as quoted by Maiden. The question then 

 arises as to whether Schimmel & Co., had the oil of tereti- 

 cornis. If they did we have no tereticornis here. The 

 marked difference between rostrata and tereticornis is only 

 in the bud according to what I can make out. The bud 

 cap of tereticornis is like a candle snuffer or sugar loaf, 

 while that of rostrata is drawn down to a beak-like form.
