These constituents vary much in amount in the oils of 

 the several species, but it is possible to form groups such 

 as the eucalyptol group, the phellandrene group, etc. The 

 refractive index of the predominant constituent will, of 

 course, influence the result, but there is a marked uniformity 

 between the members of the several groups, agreeing 

 strongly with the indications suggested by the study of 

 the leaf venations. 



Eucalyptol-pinene oils; phellandrene usually absent. 

 Refractive index mostly above 1*47 and below 1*48.
