Habitat. —The normal form is chiefly confined to the coastal districts and to 
the eastern slopes of the table-lands. As for definiteness I have given details of 
localities of the varieties, I give a few illustrative localities of the normal form. 
Victoria. —Gippsland. 
New South Wales. —Eden to Moruya, Shoalhaven River, Crookwell, north to 
Sydney and Parramatta. Very near the normal on the Mudgee line ; common 
along the North Coast. 
Queensland. —Common on coast, at least as far north as Rockhampton ; 
the Herbert River; and the Northumberland Islands. Leichhardt called some 
specimens “Scaly Gum.” 
New Guinea. —It is one of the few Eucalypts that extend to this dependency. 
Varieties of E. tereticornis. 
E. tereticornis is one of the most variable of our Eucalypts; it has an 
extensive range, and exhibits much variation even in its operculum, which is usually 
looked upon as its most characteristic organ. Eor example, the operculum of 
var. squamosa is conical and even hemispherical; a similar tendency is shown in 
var. dealbata, and especially in those forms which extend into the far interior, and 
which, I think, cannot he differentiated from E. rostrata growing in those regions. 
Var. squamosa has a peculiar glaucous appearance unique among the Eucalypts in 
the districts in which it grows; this appearance is also to he observed in interior 
forms of E. tereticornis. In fact, glaucousness is an accidental character, the same 
plant being often more glaucous at one period of the year than at another, while 
the difference in glaucousness, owing to environment, is notorious. 
Of this species we have at least four well-defined varieties. I call them 
varieties, as they run into each other and every one runs into the other and into the 
typical form. I will give instances of this later on. Mr. Huff, formerly Superin¬ 
tendent of the Botanic Gardens, found what he called no less than four forms in the 
Sydney Domain. They are all near the species type, hut all vary in liahit of tree, 
foliage, fruit, etc. 
Certain Kanimbla Valley, N.S.W. (Lowther), specimens are interesting in 
this connection. They have fruits and buds between dealbata and latifolia, forming 
indeed one of the strikingly intermediate forms. The leaves have very marked 
intramarginal veins, and the fruits remind one of those of E. punctata in shape. A 
few yards away we have a tree whose fruits are nearly normal. 
There is an instance of fibrous barked tereticornis mentioned by Bentham 
(B.E1. iii, 241). “ In one specimen from the granite hills between Nine-mile Creek 
and Broken River, Victoria, E. Mueller has appended the note' that the bark is
