“ A medium-sized tree with very hard ragged bark. Leaves slightly curved and drooping. 
Sapwood of a yellow colour, the rest dark brown; both very hard, tough, and close-grained. A pretty 
shade tree. Timber not often used, probably on account of its being so hard. It would no doubt be 
suitable for any purpose where strength and durability are required, or for turnery work.”— (Cat. 
Queensland Forestry Mus., 1904.) 
Exudation. —Mueller quotes the late P. O’Slianesy, of Rockhampton, 
Queensland, in stating that the tree exudes a large quantity of clear gum. 
Size.— 
The largest and most conspicuous Acacia in the western plains of this State, attaining a height 
of 60-80 feet and a diameter of 3 feet.—(R. H. Cambage.) 
30-50 feet at Coolabah.—(R. W. Peacock.) 
Attains a height of 50 feet, girth 6 feet, bole 30 feet; of spreading habit.—(E. F. Rogers). 
Habitat. —In the Flora Australiensis it is recorded from Queensland only, 
and the following localities are given. Near Lake Salvator, Mitchell (the type) ; 
Peak Downs ( Mueller ) ; Clarke River ( Daintree ). 
It is confined to New South Wales and Queensland so far as we know at 
present, though I expect it will he found in South Australia. 
Additional Queensland localities quoted by Mueller are:—Darling Downs 
(. Lau ); Comet River (O’ Shanesy) ; also on the Flinders and Herbert Rivers ( Free . 
Linn. Soc. N.S.W., 1890). 
As far as I know, the tree occurs north to the Queensland border, south to Dandaloo, east to 
Trangie, and west to Louth, but it is very scarce east of the Bogan and south of Nyngan. It is more plentiful 
on West Bogan, increasing in quantity and size westward to south, with the exception of within a radius 
of 10 miles from Cobar, where it was cut down for firewood or mines.—(E. F. Rogers, of Nyngan.) 
Thirty miles south of Nymagee, New South Wales, the most southern locality.—(R. H. Cambage.) 
I have it from Warialda (W. McDonald), considerably to the east of the 
above localities, with the note that it is “ eaten by stock.”
