As regards the oil obtained from the leaves, I have three authenticated analyses 
before me. No 1 is from Messrs. Baker and Smith’s “ Research on the Eucalypts,” 
and Nos. 2 and 3 are by W. P. Wilkinson :—*

It is remarkable how these analyses vary. My view is that we require 
hundreds of analyses of the oil of each species taken under circumstances as variable 
as possible before we shall he able to make accurate generalisations in regard to 
them. These should he made in all the States, just as the material for botanical 
diagnosis is obtained over areas as wide as possible. 
Flowers. —No Eucalypt produces a greater profusion of flowers than this 
one, although some (i.e. the Yellow Box, E. melliodora ) are also very free flowerers. 
It is, in consequence, very much sought after by insects, though whether the variety 
of species is in good proportion to the profusion of individuals only an entomologist 
can say. 
Bark .—This is par excellence a White Gum, its smooth hark extending right 
down to the ground. Its hark is thick, brittle, and succulent. 
Timber. —Pale-coloured, full of gum-veins, warps a good deal. Good logs 
cannot he obtained, as the barrels are usually short and crooked. The limbs bend 
and twist like wire without breaking.—(Nowland). Its chief local uses are for fuel 
and fencing (posts), as it is very durable. 
Exudation. —The remarks on the kino of E. stellulatci apply here. 
Size. —Usually a medium-sized tree, it exceptionally attains the height of 
100 feet, and a diameter of trunk of 5 or 6 feet. 
Habitat. —This tree is confined to Tasmania, South Australia, Victoria, and 
New South Wales— 
Tasmania. 
In Tasmania it is common, except the extreme south and south-west.—
