GROUP III 



CLASS (a). 



In this Group are placed the following Eucalypts yielding an oil consisting 

 principally of cineol and pinene, in which the cineol exceeds 40 per cent, 

 at the time of distillation, but under 55 per cent. Phellandrene is absent, 

 and aromadendral* very rarely occurs. 



* The name aromadendral is used throughout this work in a general sense to denote the presence of one or 

 more members of this group of characteristic aldehydes, which includes cuminaldehyde and cryptal. See also 



the article in this work on these aldehydes.
