686 SOME NEW SPECIES OF EUCALYPTUS, 



Mr. W. Biiuerlen states " that it is usually associated with E. 

 populi folio, the Green Mallee (E. viridis, Baker), and the Grey 

 Mallee (E. Morrisii, Baker), on which account it is called 

 ' Mallee Box.' I have never seen it in mallee form, and as a 

 result of my inquiries it appears that it does not grow in that 

 form." 



Of described species it is most closely allied to E. liemipldoia 

 and other " Boxes" in oil, kino, and botanical characters. 



It differs from E. conica, Deane & Maiden, in height, bark, 

 timber, oil and fruits. 



Although the two species are not easily separated on herbarium 

 material, they are never confounded in the field. 



Timber. — Hard, close-grained, interlocked, heavy, durable 

 timber, of a brownish colour. Useful for bridge-decking, posts, 

 railway sleepers, and general building purposes. It is in great 

 request at the Cobar mines for shoring the roofs. 



Kino.— Turbid in cold aqueous solution, but the turbidity is 

 removed on boiling. The constituent present besides tannin is 

 "eudesmin" (H. G. Smith). The kino is plentiful even on trees 

 not in any way injured (W. Bauerlen). 



Oil. — The yield of oil from a large number of distillations was 

 ■495 per cent. The oil contains but a small quantity of eucalyp- 

 tol, less than 5 per cent., and consequently is not a commercial 

 oil. It contains the aromatic aldehyde previously known as 

 cuminaldehyde, and which constituent appears to be character- 

 istic of true " Boxes." It has now been described and named 

 aromaclendral. 



The specific, gravity of the crude oil at 15° C. is -889. The 

 specific rotation of the crude oil is [a] j) — 137°. 



The lpevo-rotation of this oil is due to the presence of the aro- 

 matic aldehyde (aromadendral). 



Phellandrene is not present in this oil (H. G. Smith).
