WATTLES AND WATTLE-BARKS.

4. Acacia rig cm, A. Cunn., B.Fl., ii., 337. 14 Nealie,” or “Needle Bush.” 
Bark from an old tree, from near Hay, N.S.W., yielded the author 1905 
per cent, of extract, and 6*26 per cent, of tannic acid. ( Proc . R.S ., N'.S.W., 
1887, p. 88 .) 
It consists of hut little else than layers of fibre. A dry-country wattle. 
South Australia, Victoria, and New South Wales. 
5. Acacia calamifolia , Sweet, B.Fl., ii., 339. “Willow” or “Bitoo^r 
Wattle.” “ Wallowa” of the aboriginals of Lake Ilindmarsh Station 
(Victoria). * 
A sample of bark is in the Technological Museum, received in the year 
1883, was stated to contain 20*03 per cent, of tannic acid, according to an 
analysis by Mr. Thomas, of Adelaide. It was labelled “ A. calamifolia .” I 
analysed this bark, which came from the Murray 'Flat Bangcs, South 
Australia, and found it to contain 36*00 per cent, of tannic acid, yielding no 
less than 03*1 per cent, of extract. It is nearly ft of an inch thick, solid, 
smooth, containing very little fibre, and hardly to be distinguished from 
A. pycnantha bark. I received it, however, under the namo by which I now 
describe it, and the tree is not personally known to me. 
The bark is a superb one. As to the discrepancy between my analysis 
and that of Air. Thomas, I can state that I have proved that barks stored in 
a dry place increase in percentage of tannic acid ; but what that percentage 
is, or whether any generalization can bo made, my experiments hardly yet 
warrant me in stating. Mr. Thomas* figures may have been based on a 
very different sample of the parcel to that which has come into my hands, 
but what the percentage of tannic acid was in my particular specimen in 
1883, can only be guesswork. My analysis was made April, 1890. I draw 
attention, in this context, to the footnote at page 16, in regard to my 
analyses all being calculated on the bark freed from moisture. 
I received this particular bark from a firm of the highest reputation, and 
I am confident that no transposition of labels has occurred in this Museum. 
80 far as 1 know, A. calamifolia does not attain a size sufficient to yield bark 
similar to that under examination, and I trust that correspondents will 
kindly enable me to state the proper position of A. calamifolia as a bark- 
yielding wattle. 
A. calamifolia is recorded from South Australia, Victoria, and the extreme 
west of New South Wales. 
G. Acacia vemiciflua , A. Cunn., B.Fl., ii., 358. 
This small tree (height, 20 to 25 feet, with a diameter of 2 to 5 inches), 
exudes a sticky substance from the leaves, hence the specific name. The 
bark reminds one irresistibly of cascarilla bark. It is full of fibre, and of no 
use to the tanner. A specimen collected in April, 1889, on the Delegate 
lliver, N’.S.W., in granite country, was analysed by me the following April, 
and found to yield 22*35 per cent, of extract, and only 3*16 per cent, of 
tannic acid. 
Found in New South Wales, Victoria, South Australia, and Tasmania, 
chiefly on mountains and high table-lands. In the south-east in such 
situations it does not extend, farther north than the Bombala District; out 
west it was found both by Cunningham and by Mitchell
