length of the leaf, other lateral veins more transverse. Buds in clusters on 

 axillary peduncles 3 lines long ; calyx tube almost sessile, 2 lines long ; operculum 

 shortly conical. 



Fruit. Hemispherical, capitular, pedicel up to 2 

 lines long ; rim domed ; valves scarcely or 

 not exserted ; 3 lines broad and 3 lines long. 



These have a strong resemblance to those of E. dives 

 in being shiny, yellow in colour, but the rim is slightly 

 more domed, or a small form (not illustrated) of 

 E. capitellata, but pedicellate. 



Habitat. Black Mountain, Arrnidale, Barber's Creek, New 

 South Wales. 



REMARKS. -A tree of rather rare occurrence, being only known so far from two localities (supra). 

 The buds and leaves closely resemble those of E. stettulata, but the bark is stringy. The venation belongs to 

 the same class as that of E. dives and E. stellula/a or E. phlebophylla. 



ESSENTIAL OIL. Material for distillation was received from Black 

 Mountain, New England District, N.S.W., in August, 1907. The yield of oil 

 was 0-37 per cent. The crude oil was dark-coloured and had a terpene-like odour. 

 The constituents present were laevo-rotatory pinene, phellandrene, cineol, esters, 

 and the sesquiterpene. 



The crude oil had specific gravity at 15 C. = 0-9095; rotation # -- 8-1; 

 refractive index at 20 = 1-4790, and was soluble in 6 volumes 80 per cent, alcohol. 

 The saponificatiqn number for the esters and free acid was 13-4. 



On rectification, 2 per cent, distilled below 157 C. (corr.). Between 

 157-175, 54 per cent, distilled; between 175-225, 7 per cent, came over, and 

 between 225-270, 32 per cent, distilled, the greater portion above 260. These 

 fractions gave the following results : 



First fraction, sp. gr. at 15 C. = 0-8705; rotation a D - - 15-9; refractive 



index at 20 = 1-4653. 

 Second ,, ,, ,, = 0-9006; rotation - - 13-6 ; refractive 



index at 20 = 1-4713. 

 Third ,, ,, ,, = 0-9428; rotation too dark; refractive 



index at 20 = 1-4958. 



The first fraction was again distilled, when 36 per cent, came over below 

 157 C., and 38 per cent, between 157-160. These two fractions gave the 

 following results : 



First fraction, sp. gr. at 15 C. = 0-8665 '> rotation D - - 19-1 ; refractive 



index at 20 = 1-4640. 

 Second ,, ,, = 0-8693; rotation D - 17-4; refractive 



index at 20 = 1-4647. 



The nitrosochloride was easily prepared with the first fraction, and this 

 melted at 104 C. It is thus evident that the principal constituent is pinene. 

 Cineol was present, but not more than 5 to 8 per cent. Phellandrene occurs only 

 in small quantity. 



The above characters distinguish the oil of this species from that of E. 

 stettulata.
