Mi.- above sample was stored in the dark, and in December, [gig, was 

 again analysed. Verj little alteration had taken place during the twenty years 

 the oil had been kept. On distillation 85 pei cent, came ovei belou

 The cineol was determined bj the resorcinol method in the rectified 

 portion. When calculated foi the 1 rude oil the resull was 2g per cent. By the 

 rapid phosphoric arid method il was 21 per cent, when calculated for the crude 

 oil.

While Stringybark 



Systematic. A tall tree. Bark thick, stringy, "I a clean, reddish colour, 

 or hoary on the external fibres. Abnormal leaves ovate, lanceolate, with 

 crenulate edges, scabrous, oblique, acuminate, on a petiole oi aboul \ inch 

 long; venation line, lateral veins oblique, parallel, intramarginal vein removed 

 from the edge. Leaves oi mature trees falcate, lanceolate, oblique, medium 

 size, often shining; venation similar to that of the early leaves. Peduncles 

 axillary, very numerous at the base oi the branchlets, compressed, with many 

 flowers. Calyx 1 to 3 lines long, tapering into a short pedicel; operculum 

 conical, obtuse, about as long as the calyx. 



Fruit. Hemispherical, very shortly pedicellate or 



sessile; rim wide, red coloured; valves not 

 exserted, or only slightly so; about \ inch 



in diameter. 



In shape nearest to E. capttellata, but smaller, and 

 only rarely compressed, as obtains in that species. They 

 are also not unliki E. Wilkinsoniana. Rim often a 

 little wider than shown in the jv. 



Habitat. Probably the most widely distributed species on 

 the 1 oast and tableland ol New South \\ all 

 \'i, toi ia, and Queensland.
