veins spreading, intramarginal vein not far removed from the edge. Flowers 

 seven to ten, on axillarj peduncles. Buds 4 to 6 lines long; calyx tube under 

 2 lines in diameter, pyriform; operculum hemispherical, very shortly acuminate. 



Fruit. -Hemispherical to pyriform, on a pedicel of 

 from 1 to 3 lines long ; rim thin, contracted 

 at the edge; valves inserted ; about 2 to 3 

 lines in diameter.

The fruits are very like those of E. polybractea. 



Habitat. — On the hills near Girilambonc, thence across country 

 to Cobar; also 7 miles out from Coolabah, on the 

 Wilga Downs Road, Wyalong, New South Wales; 

 Victoria (back country).

REMARKS.— This is a " Mallee " with an 

 extensive range between the Bogan and Lachlan 

 Rivers. The fruits vary little in size, and very 

 often cannot be distinguished from those of E. 

 Woollsiana, R.T.B., a species with a " Box " bark, 

 pale coloured timber, and with variable leaves. 

 It has li.tle botanical connection with E. gracilis, 

 and is a very distinct and constant species 

 throughout its geographical distribution. The 

 bark is of a fibrous nature, but not deeply 

 furrowed, and of a peculiar rich yellow colour on 

 the inner side. Mr. Maiden synonymises it 

 under E. acacioides, A. Cunningham (Crit. Rev. 

 vol. ii, p. 4-,*, and in a footnote states: — 

 " A. Cunningham discovered this plant first, and 

 first gave it a name .... Bearing in 

 mind the haphazard circumstances under which 

 Eucalyptus names were sometimes promulgated 

 in the early days, the name is tenable, and 

 doubtless would have been adopted bv Mr. Baker, 

 had he known it. To Mr. Baker belongs the 

 credit of the first description of this species, and. 

 under the circumstances, I am in doubt as to 

 whether the name viridis should not be adopted." 



ESSENTIAL OIL. -Leaves and 



terminal branchlets for distillation 

 were obtained from Girilambone, 

 N.S.W., in January, 1900. The 

 yield of oil was i-i per cent. The 

 crude oil was of a light orange- 

 brown colour, and had an odour 

 indicating the presence of aroraa- 

 dendral. Pinene was present, but 

 phellandrene was absent. Cineol 

 was detected, about 10 per cent, 

 of that constituent being present 

 in the crude oil. Aromadendral 

 was determined in the higher 

 boiling portions, and its presence 

 was also indicated by the left rota- 

 tion of the crude oil being greater 

 than that of the first fraction. The 

 amount of esters was not large. 



The crude oil had specific gravity 

 at 15 C. = 0-9006 ; rotation 

 a D — 8-i°; refractive index at 20° = 1-4771, and was soluble in 2 volumes 80 per 

 cent, alcohol. The saponification number for the esters and free acid was 5-7.
