There is a very strong resemblance between the oil of 

 this Eucalypt and that of "Narrow Leaf," E. oieorifolia, 

 and for commercial purposes no marked differences should be 

 detected between the products of the two species. 



7. Eucalyptus oleosa, F. v. M. (Neder Kruid. Arch., iv., 



132). 



"Red" or "Water Mallee." 

 PL lii. 

 This Eucalyptus species, one of the large group known 

 as "Mallees," preserves its specific botanical and chemical 

 •characters throughout its geographical distribution. It is 

 fully described, both systematically and chemically, in our 

 work on the "Eucalypts and their Essential Oils," p. 118. 



8. Eucalyptus uncinata, Turcz. 

 A "Mallee." 



In this State it occurs on Kangaroo Island, as well as 

 the mainland, and is fairly constant in its characters, being 

 always found as a "Mallee." 



This is a species that so far has eluded us, and we have 

 not yet been able to procure material for chemical investiga- 

 tion. 



■9. Eucalyptus cneorifolia, DC. (Prod., iii. p. 220). % 

 ' 'Narrow-leaf Mallee. ' ' 

 PL xlix. 



The specific rank of this Eucalypt has so far been unchal- 

 lenged. It is the "Narrow-leaf Mallee" of Kangaroo Island, 

 although it. is not uncommon to find it in small tree form. 

 A figure is given of it in DC. Mem. Myrt., t.p., according 

 to Bentham (loc. cit.), but so far it has not been depicted 

 in any Australian publication. A figure is, therefore, given 

 with these results, which will more definitely place it for 

 future reference for botanical workers, both in and outside 

 Australia (pi. xlix.). 



Essential Oil. 



Leaves and terminal branchlets of this species for distil- 

 lation were collected at the Kingscote end of Kangaroo Island 

 in the month of June. This species is the principal one on 

 the island from which Eucalyptus oil for pharmaceutical 

 purposes is distilled. It is one of the "Mallees," or shrubby 

 Eucalypts, and is a very common species on Kangaroo Island.
