19. Acacia melanoxylon, #.2r., (Syn. A. arcuata, Sieb.); N.O., 
Leguminose, B.FI., ii., 388. 
Variously called ‘ Blackwood,” ‘“ Lightwood,” ‘Black Sally,” 
“* Hickory,” “ Silver Wattle.” 
The bark of this highly valuable timber has usually gone to 
waste, after the splendid wood has been obtained from the logs. 
The bark is, however, rich in tannic acid, and ought not to 
be left unutilised, though no trees of this species should be sacri- 
ficed for the sake of their bark alone. (Mueller.) A sample of 
bark from Monga, near Braidwood, N.S.W., yielded the author 
20.63 per cent. of extract, and 11.12 per cent. of catechu-tannic 
acid. (Proc. R.S., N.S.W., 1887, p. 31. The leaves (loc. ctt., 
Pp. 259) yielded 23.22 per cent. of extract, and 3.382 per cent. of 
tannic acid. 
All the colonies except Western Australia and Queensland. 
20. Acacia neriifolia, A. Cunn., N.O., Leguminose, B.FI., ii., 
363. : 
‘© Black Wattle.” 
The following analysis of the bark is given by the Queensland 
Commissioners, Colonial and Indian Exhibition, 1886 :—Tannin, 
13.91 per cent.; extract, 17.87 per cent. 
Northern New South Wales and Queensland. 
21. Acacia Oswaldi, 7.v.47., N.O., Leguminosz, B.FI., ii., 384.- 
“ Miljee.” (For other vernacular names, see ‘‘ Timbers.”) 
The bark from an oldish tree has been examined by the 
author, with the following result :—Extract, 20.7 per cent.; tannic 
acid, 9.72 percent. (Proc. R.S., N.S.W., 1887, p. 189.) 
In all the colonies except Tasmania. 
22. Acacia pendula, var. glabrata, 4. Cunn., N.O., Leguminosz, 
B.F1., 11., 383. 
‘“* Yarran.”’ 
Bark from this variety, obtained from near Hay, N.S.W., 
yielded the author 17.91 per cent. of extract, and 7.15 per cent. - 
of catechu-tannic acid. (Proc. R.S., N.S.W. 1887, p. 89.) 
New South Wales and Queensland.
