46 WATTLES AND WATTLE- BARKS. 



The first specimen caine from Hammond, S.A., the exact locality of the 

 other is unknown. 



A dry-country species, found in the interior of New South Wales, Victoria, 

 and South Australia. 



20. Acacia poclalyricefolia, A. Cunn., B.PL, ii, 374. 



Sometimes called "SILVER WATTLE." 



The bark is used in tanning, giving a light colour to leather. The following 

 analysis is given by the Queensland Commissioners, Colonial and Indian 

 Exhibition, 188G : Tannin, 12*40 per cent. ; extract, 29'50 per cent. 

 (Bailey). 



Northern New South Wales and Queensland. 



21. Acacia vestita, Ker, B.PL, ii, 375. 



Bark from near Bombala, N.S.W., yielded the author 5OS2 per cent, of 

 extract, and 27'98 per cent, of tannic acid (Proc. R.S., At.S.W., 1887, p. 89) . 



It grew on limestone country, and was from a tree 18 inches in diameter. 

 Analysis of a second sample from the same district gave an even better 

 result, viz. : 83*2 per cent, of tannic acid, and 61'51per cent, of extract. 

 This is very similar in appearance to the bark of A. decurrcns, for which it 

 might be substituted without detriment. It is a most useful bark, but, un- 

 fortunately, not of wide distribution. It is at the same time one of the most 

 beautiful of wattles, and therefore I feel the responsibility of pointing it out 

 as a fit subject for the bark-stripper. 



Southern New South Wales and Northern Victoria. It is a highland 

 species in the Monaro, N.S.W., and there very rare. 



22. Acacia pravissima, P. v. M. 3 B.FL, ii, 375. 



This tall shrub has a thin, dark-grey to blackish bark, which yields a light- 

 coloured powder, containing an unusually small proportion of fibre. But the 

 expense of stripping it would bar its use practically, even if the percentage 

 of tannic acid caused it to be a temptation to the stripper. A sample from 

 Jindabyne, Snowy River, collected January, 1890, and analysed the following 

 April, gave tannic acid 10'GG per cent., and extract 3T75 per cent. It was 

 grown on granite soil, and was from shrubs 8 to 12 feet in height, and having 

 a diameter of 1 to 3 inches. 



Southern New South Wales and Victoria. A highland species, found on 

 the banks of the Snowy Eiver.
