Victoria, New South Wales and Queensland. 
16. Acacia leptocarpa, A. Cunn., N.O., Leguminose, B.F1., ii.,

cent.; extract, 26.41 per cent. (Staiger.) 
Northern Queensland. 
17. Acacia longifolia, Wrl/d.; N.O., Leguminose, B.FI., ii., 
397- . 
“ White Sallow.” ‘' Golden Wattle.” 
The bark of this tree is only half as good as that of A. decurrens. 
It is used chiefly for sheepskins. The following is an analysis of 
this bark :—Tannin, 12.67 per cent.; extract, 32.05 per cent. 
(Staiger.) A specimen from Cambewarra, N.S.W., yielded the 
author 30.35 per cent. of extract, and 18.93 per cent. of catechu- 
tannic acid. (Proc. R.S., V.S.W., 1887, p.go.) Other specimens 
(a) from Oatley’s Grant, near Sydney, and (4) Ryde, near Sydney, 
yielded the author (Joc. cz#/., p. 190) 24.91.and 23.53 per cent. of 
extract respectively, and 15.34 and 15.99 per cent. of tannic acid 
respectively. Both were from much younger trees than the 
specimens from Cambewarra. The leaves (/oc. czt. p. 260) yielded 
21.55 per cent. of extract, and 1.932 per cent. of tannic acid. 
South Australia, Tasmania, Victoria, New South Wales, 
Southern Queensland. 
18. Acacia longifolia, W72/d., var. Sophore, (Syn., A. sophore, 
R.Br.; Mimosa sophore, Labill.); N.O., Leguminosz, B.FI., 
ii., 398. 
This bark is used for tanning light skins in Queensland, but 
as it is comparatively weak in tannin it fetches but a low price. 
Mr. W. Adam informs me that Sydney fishermen often tan their 
sails and nets with this bark, and are well pleased with it, the 
articles being pliable after use. 
South Australia, Tasmania, Victoria, New South Wales and 
Southern Queensland. Chiefly on the coast.
