430 AUSTRALIAN NATIVE PLANTS. 
Allusion to its fibrous bark is also made in the aboriginal name in 
Gippsland of the tree (“ Wangara’’=bark-string). ‘‘Woorun” is the 
aboriginal name at Coranderrk Station (Victoria), while “ Tirba-twebin” is 
the name at the same place given to the variety formerly called £. fissilis. 
A variety of this gum (E. radiata) is called in New South Wales ‘‘ White 
Gum ” or “ River White Gum.” The aboriginal name in the counties of 
Cumberland and Camden was ‘ Kayer-ro.” A variety of £. amygdalina 
growing in the south coast district of New South Wales, goes by the name 
of ‘ Ribbon Gum,” in allusion to the very thin, easily detachable, smooth 
bark. This is also £. radiata probably. A further New South Wales 
variety goes by the name of ‘“Cut-tail’’ in the Braidwood district. 
The author has been unable to ascertain the meaning of this absurd 
designation. These varieties are, several of them, quite different in leaves, 
bark, and timber, aud there is no species better than the present one to 
illustrate the danger in attempting to fit botanical names on Eucalypts when 
only the vernacular names are known. 
This is probably the tallest tree on the globe, individuals 
having been measured up to 4ooft., 410ft., and in one case 42oft., 
with the length of the stem up to the first branch 2g5ft. The 
height of a tree at Mt. Baw Baw (Victoria) is quoted at 471ft. 
This timber is useful for many kinds of carpentry work ; 
in drying it does not twist. When it forms straight, long stems, 
as in rich forest valleys, it splits with remarkable facility, and in 
one particular instance a labourer split 620 five-foot palings in 
one day. The timber of 2. amygdalina is, as a rule, particularly 
well adapted for shingles, palings and rails, and also for use in 
shipbuilding, especially keelsons and planking. It does not form 
a very superior fuel. (Mueller.) 
“ Cut-tail’’ grows with a straight bole over z2ooft. high, 
and with a diameter of 6 to 8ft. Its wood is fissile in the 
highest degree, since it can be readily split almost to the thinness 
of paper. A sample of this timber from Haydon’s Bog, near 
Delegate, cut in March, 1885, is in the Technological Museum. 
It is very straight in the grain (as might be expected), and very 
easy to work. 
The timber of Z. amygdalina is comparatively light, as it 
floats on water. A slab in the Technological Museum, which has 
been seasoned over twenty-five years (having been exhibited at 
the London International Exhibition of 1862 as Z. radia/a), has
