veins oblique, spreading, 1he distant ones being more distinct, intramarginal 

 vein removed from the edge. Inflorescence in axillary or terminal panicles; 

 pedicels about 3 lines long, slender. Calyx conical, 2 lines in diameter, operculum 

 hemispherical, shortly acuminate. 



Fruit. Conical ; rim thin, contracted, sometimes 

 lacerated, valves deeply inserted; about 2 

 lines or slightly more in diameter. 



In general shape they resemble E. conica, E Fk tolieri 

 and E polyanthemos, but arc larger. 



Habitat. Camboon, Rylstone, Hargravcs, Wellington, New 

 South Wales. 



REMARKS.- This variety is placed with E. o;<ali/olin on account of a resemblance in the morphological 

 fharaclers of (lie fruits (partly) and buds, as well as the bark and nature of the timber. The trees of the two (the 

 type and variety) are quite different in the field, and timber-getters and settlers never confound them. The constant 

 shape of the leaves and the pyriform fruits and chemical constituents are the principal features of difference between 

 it and the type. 



ESSENTIAL OIL. Leaves and terminal branchlets for distillation were 

 obtained from Camboon, N.S.W., in March, 1901. The yield of oil was 0-58 

 per cent. The crude oil was of a light amber colour, and had an odour resembling 

 those belonging to the cineol-pinene class of Eucalyptus oils. Pinene and phellan- 

 drene were both present, and also a good quantity of cineol. It is unusual for an 

 oil containing so much phellandrene to be so rich in cineol, particularly as the 

 terpene in the richer cineol oils is generally pinene. The higher boiling portion 

 contained the sesquiterpene. The Isevo-rotation of the oil was largely due to the 

 presence of phellandrene ; the amount of esters was not large. 



The crude oil had specific gravity at 15 C. = 0-9083 ; rotation a D 4-26 ; 

 refractive index at 20 = 1-4654, and was soluble in 2 volumes 70 per cent, 

 alcohol. The saponification number for the esters and free acid was 3-8. 



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

 157-188, 92 per cent, distilled, and between 188-250, 3 per cent, distilled. 

 These fractions gave the following results : 



First fraction, sp. gr. at 15 C. = 0-9068 ; rotation D - - 5-9. 

 Second ,, ,, = 0-9336; ,, not taken. 



The cineol, determined by the phosphoric acid method in the large 

 fraction, was 48 per cent. (O.M.), indicating about 45 per cent, in the crude oil. 



The oil from this variety differs from that of E. ovalifolia itself in con- 

 taining more pinene and much more cineol. 



This sample had been stored in the dark, and in September, 1919, was 

 again analysed. The Isevo-rotation had diminished, and the cineol increased 

 a little in amount. 90 per cent, distilled below 190 C. The crude oil and the 

 rectified portion gave the following results : 



Crude oil, sp. gr. at 15 C. = 0-9148; rotation 1-4; refractive 



index at 20 = 1-4658. 

 Rectified portion ,, ,, = 0-9099; rotation a D - - 2-2; refractive 



index at 20 = 1-4621. 



The cineol was determined by the resorcinol method in the rectified 

 portion; when calculated for the crude oil the result was 67 per cent. By the 

 rapid phosphoric acid method, it was 56 per cent, when calculated for the crude oil.
