they form partition walls between which the fibres are packed. In the tangential 
cut the medullary rays appear as interrupted perpendicular thick lines, and in the 
radial cut as large, irregular blotches. 
Long straight pieces of stem arc rare, so that it would be very difficult to 
procure a good supply of this remarkable wood for cabinet-making purposes. 
But the most remarkable character about this timber is the difficulty of 
burning it. Of course most Casuarina timbers form the best fuel woods in 
Australia, but the Thready-barked Oak is such a bad burner that it owes its 
preservation to that character. Not only do the trees resist the ravages of the bush- 
fires to which their fibrous barks particularly subject them, but man does not trouble 
to fell them for fuel. The main forest of this species that I saw near the town 
of Warialda would have been cut down long ago for local requirements but for the 
character I have mentioned. 
Size. —A small tree, 10 to 30 feet high, with a diameter 0-12 inches, and 
with pendulous branches. It is like C. distyla, stooling in habit in the early stage, 
eventually growing into a single stem, generally much crooked and branched, with 
a wide spreading top. 
Habitat. —This species is confined to Northern New South Wales and 
Southern Queensland. 
Queensland. 
In the description we have, near Roma (F. M. Bailey), near Toowoomba 
(C. Hartmann), and I think we may correctly add Leichhardt’s locality. In the Catal. 
Queensland Forestry Museum , 1904, we have— 
Trees fairly numerous on poor sandy and stony land in the neighbourhood of Miles and Yuelba and 
other western parts. 
New South Wales. 
I received it from Emmaville, in July, 1894, from a correspondent whose 
name I have forgotten. It does not appear to be abundant there, as my collector 
only found one tree there in 1903, and he could not find any in 1905. 
Mr. Andrew Murphy said he had collected it near Jennings. I do not think 
he is mistaken, but I have no specimens from that locality. 
I still did not know where to get N.S.W. specimens for my correspondents, 
and Avrote to my friend, Rev. H. M. R. Rupp, of Warialda, asking him if he kneAv. 
He replied that it grows in great abundance about Warialda, and that he has seen 
it about Coolootai, Yetman, and Wallangra. I visited Warialda, and found the 
species very abundant, so that it is not so excessively rare in New South Wales as I 
had imagined it to be. 
It frequents sterile ironstone, gravelly ridges. 
Other oaks are scarce in the district. I noticed C. Luehmanni , R. T. Baker, 
near Warialda.
