WATTLES AND WATTLE-BARKS. 
26. Acacia implexa , Bentb., B.F1., ii., 389. 
I have analysed a sample of this hark ( Proc ., R.S ., N.S.W., 1888, p. 270). 
It gave 20*54 per cent, of extract, and 7*82 per cent, of tannic acid. It is 
slightly bitter to the taste, but this sample is from an old cultivated tree, 
and the bitterness is less noticeable; hoary-looking, in layers and flakes; 
average thickness, i in. 
Victoria, New South "Wales, and Queensland; chiefly a coast species, and 
on eastern mountain slopes. 
27. Acacia Jiarpophylla , F.v.M., B.F1., ii., 389. The common “ Brigalow 
so called because it forms the scrubs of that name ; the meaning of the 
word is unknown. 
This tree is said to yield a considerable amount of tan-bark. 
Central Queensland. 
2S. Acacia iinervafa, DC., B.F1., ii., 390. “Black Wattle” or “Hickory,” 
“Myiinbarr” of the aboriginals of Hlawarra (New South Wales). 
The bark is used by tanners, though it is not so rich as that of A. deeurrens. 
(W. Dovegrove.) Nevertheless, it is a valuable bark ; specimens from 
Cambewarra, N.S.W., yielded the author up to 58*03 per cent, of extract, 
and 30*4 per cent, of tannic acid. The colour of this sample was dark brown; 
the inner bark warm red-brown; the outer bark deeply fissured or flaky, 
which makes it more or less pulverulent; the inner bark contains abundance 
of strong fibre; diameter, 12 inches ; height, 20 to 25 feet; locally called 
“ Black Wattle.” (Free. R.S ., N.S. W., 18S7, p. 90.) 
A second sample from the same locality gave 2S*2 per cent, of tannic acid, 
and yielded 51*5 per cent, of extract. 
Additional samples of barks of this species are desired. 
I have examined a specimen from Tomerong, near Jervis Bay, N.S.W. 
(between Nowra and Milton), which was collected February, 18S8, and 
analysed the following September (Proc. R.S. , K.S.W.. 1888, p. 273). As 
received, it bad had its first crushing in the mill, nevertheless it was possible 
to pick samples showing a fair proportion of inner and out er bark. The outer 
bark is somewhat scaly, and the inner bark is light reddish-brown and very 
fibrous. It cannot be mistaken for A. deeurrens bark owing to its fibrous 
nature. It gave extract 37*8 per cent.; tannic acid, 19*3 per cent. 
This sample was taken from bulk actually used by a tanner, and it will be 
found, in general, that barks containing 20 per cent, of tannic acid are 
commonly used by country tanners; in fact, if bark of a species gives as 
high as 15 per cent, of tannic acid, it is worthy of enquiry whether richer 
specimens are available. 
This is a coast species of New South Wales and Queensland. It does 
not extend further south in our Colony than the Ulladulla District. 
29. Acacia flavescens, A. Cunn., B.F1., ii., 391. 
This bark contains 10*2 per cent, of tannin. (Staiger.) Queensland. 
30. Acacia longifolia , Willd., B.FI, ii., 397. “Golden Wattle,” “White 
Sallow,” “Sally,” “Hickory,” &c. 
The hark of this tree is considered in Queensland to he only half as good 
as that of A. deeurrens. It is used ehioflv for sheepskins. Tne following is 
an analysis of this hark Tannin, 12*G7*per cent.; extract, 32*05 per cent.
