ESSENTIAL OIL. Leaves and terminal branchlets for distillation 

 wrif obtained from National Park N.S.W., in September, cgoo. The yield ol 

 oil was <>• ; per cent. 1 1 1< crude oil was ghl ambei in colour, and had .1 

 peppermint odour due to the presence oi a small quantity ol piperitone. It 

 contained a large quantitj oi phellandrene, bu1 onlj .1 small amounl oi pinene. 

 < ineol was present, but nol more than aboul co per cent, in the firsl fraction. A 

 lemon odour was detected in the portion distilling al aboul 230 C, so that 

 probably citral occurs in the nil. especially a- the presence oi a high-boiling 

 aldehyde was shown. Esters were only presenl in verj small amounl Eudesmol

 The crude oil had specific gravi t \ a 1 r.5 C. 0-8795 rotation ■ 27-5°; 

 refractive index at 20 = 1-4880, and was insoluble in 10 volumes 80 per cent,

155. Eucalyptus coccifera. 



(Hook., f., in Lond. Journ. Bot., vi, 477, 1847.) 



Systematic- A small tree generally very glaucous, with a smooth white 

 bark. Abnormal leaves opposite, sessile or shortly petiolate, oval, rarely obovate, 

 mucronate, about 1 inch long. Normal leaves lanceolate or narrow elliptical, 

 usually acuminate, uncinate, thick and shining, 2 to 3 inches long; venation not 

 prominent, intramarginal vein well removed from the edge, lateral veins oblique. 

 Flowers sessile, from three to six on axillary or lateral peduncles, thick, flattened 

 upwards, 2 to 4 lines long. Calyx tube prominently angled tapering to base, 

 3 lines long; operculum very short, flat or depressed rugose. 



Fruit. Broad, turbinate, sometimes conoidal ; rim 

 broad, flat or somewhat domed ; valves 

 scarcely exserted ; 5 lino long and 6 lines 

 in diameter. 



These frails arc fairly characteristic, perhaps the 

 nearest in shape- arc those of !•".. hsemastoma, tlial is the 

 pedicellate form. The sessile fruits arc near perhaps la 

 (host 0) E, St. Johni, except that this rim is nearly flat. 



Habitat. Confined i" rasmania, at high elevations.
