Two samples have been examined by me, and the following is an account of them. In view of the 
scarcity of good gum-arabic, it would be a useful addition to our raw products if abundant supplies of it 
could be obtained. I have not heard of a gum being yielded by any other Australian species of Flindersia 
in quantity. 
Sample I.—From between the Lachlan and Darling Rivers, N.S.W. A most valuable gum. It is 
in pieces as large as pigeons’ eggs, and I have seen a piece half as large as an emu egg, clear and of 
excellent quality, with only a small portion of bark at the place of attachment to the tree. In parts of 
the interior it is said to be fairly abundant. In some cases it remains in the liquid state on the trees for 
some little time before hardening, or else exudes very rapidly, for it is frequently brought to Sydney in 
pieces as long as an ordinary earthworm, and of the same average diameter. 
It dissolves readily and completely in cold water. It hardly appears to affect the transparency and 
absence of colour of pure water. In this respect it may be ranked very closely to picked Turkey gum- 
arabic. It possesses the faint cloudiness which an aqueous solution of gum-arabic soon assumes. 
Size. —Height 20 to 40 feet, with a stem diameter of 12 to 18 inches. 
Habitat. —This is a dry country species. It occurs only in New South 
Wales and Queensland. In our own State it is found over a large area of the 
Western Division, e.g., in the vicinity of the Darling, Lachlan, Bogan, Macquarie, 
Castlereagh, and other inland rivers. T have it from a number of localities, hut 
would he glad to hear of it from others in order to construct a “ curving boundary” 
of its range. 
As regards Queensland, Bailey only records F. maculosa from St. George, and 
F. Strzleckiana from “ Brigalow Scrubs of the Leichhardt district and other inland 
parts.”
