Fruits pilular; rim thin, contracted, about 2-3 lines in diameter; 

 on a pedicel of from 1 to 3 lines long. 



Hah. — On the hills near Girilambone, N.S.W., thence across 

 country to Cobar; also seven miles out from Coolabah on the 

 Wilga Downs Road (W. Bauerlen). 



Timber. — A hard, close-grained, interlocked, yellowish-coloured 

 timber. Being a Mallee, it is only rarely found in tree-form, 

 when it has a tendency to pipe. 



Oil. — Leaves obtained from Girilambone, New South Wales, 

 16th January, 1900. 



Average yield of oil = 1*06 per cent. 



The crude oil is of a light orange-brown colour, and has an 

 odour indicating the presence of cuminic aldehyde; no eudesmol 

 was detected. Phellandrene is not present. Eucalyptol was 

 present, but the oil contains less than 10 per cent, of that con- 

 stituent; lrevopinene was also present. Cuminic aldehyde was 

 determined in the higher boiling portion of the oil. 



The oil commenced to distil at 167° C.,* between 167° and 

 172° C. 32 per cent, distilled, mostly ltevopinene; below 183° C. 

 80 per cent, had distilled, and 95 per cent, was obtained below.

Specific gravity crude oil at 15° C. = 0-9006. 



Specific gravity fraction 167-183° C. at 15° C. =0-8882. 



Specific rotation crude oil = [a] jy — 8-90. 



Specific rotation fraction 167-183° C. = [a] D — 82°. 



This oil at present has no commercial value (H. G. Smith). 



Kino. — Friable; when its aqueous solution is extracted with 

 ether it is found that eudesmin exists alone, aromadendrin being 

 entirely absent. A very dilute aqueous solution gives a green 

 colouration with one drop of ferric chloride (H. G. Smith). 



This species, along with another, is figured on the same plate 

 by Baron von Mueller in his Eucalyptographia (Dec. iii.) under 

 the name of E. gracilis, F.v.M. As by a natural classification it
