Botanical Name. — Eucalyptus, already explained, see page 34, Part II; 
melliodora — mel, mellis, honey, oclora, of a sweet or pleasant smell. 
Vernacular Names. —The commonest “ Yellow Box” of New South Wales 
and Victoria. “Yellow Jacket” of the interior, the inner bark being of a yellowish 
colour. In the Merriwa and Cassilis district it is as often called Yellow Gum 
as Yellow Jacket {see “Bark”). It is sometimes called “ Honey-scented Gum,” 
owing to the perfume of its flowers. 
* Aboriginal Names. —By the aborigines of Gippsland it is known as 
“ Dargan,” according to Mr. A. W. Howitt. I do not know any New South Wales 
aboriginal name for a tree which is sure to have had a name. 
Leaves. —The following particulars in regard to the oil from this species are 
taken from Messrs. Baker and Smith’s Research on the Eucalypts :— 
Specific gravity 
at 15° C. 
Specific rotation. 
Saponification 
number. 
Solubility in 
Alcohol. 
Constituents found. 
0-9042 to 0-9321 
+ 5-36° to + 6-19° 
7-21 to 21-96 
1vols. 70 % to 
Eucalyptol, pinene, phellandrene. 
6 vols. 70 °/ a . 
The same authors* give the specific gravity of the crude oil as 0 - 905 and of 
the rectified oil, 0 902, the latter containing 58 per cent, of cineol (eucalyptol). 
They further state that the cineol content of the oil increases towards the winter, 
hut they are of opinion that the higher percentage of cineol has no influence on the 
specific gravity. 
Mr. E. J. Parry, B.Sc.,t gives somewhat different figures, viz. :—Specific 
gravity, 0'917 ; specific (optical) rotation, 0 o- 37' and 52 per cent, of eucalyptol. 
Mr. Parry challenges the statement that the percentage of eucalyptol is practically 
independent of the specific gravity. 
Messrs. Baker and Smith’s rejoinder follows. + Mr. Parry at the same placet 
maintains the correctness of his observations, and there the matter rests for the 
present. 
Flowers. —This tree, like all of the Boxes, is an esteemed honey-yielder. 
I send, by post, a sample of the great honey-producer, locally known as Yellow Box, and consisting 
of flowering blossoms and seeds, and wish to have same identified with a view to have this timber preserved 
on Forest Reserve No. 27,767 of 2,500 acres, as well as on new Goldfield Reserve of about 5,000 acres, as 
I am aware that this species of tree will produce more value in honey than the grass under them in wool. 
In fact, there are about 70 acres of this timber on my land, and some seasons I get more value in honey than 
if I had it cropped with good wheat at a fair price.—(James Brogan, of Attunga.)
