Ahonginal Names. — Formerly called " Ur-root " by the Tarra (Victoria) 

 aborigines. Native name on the Castlereagh Eiver, JST.S.W., " Eumung," 

 according to the late Eev. Dr. "Woolls, but I would point out that at least 

 three other western New South Wales wattles share that name. 



Flowers. — At one time a well-known London firm of perfumers stated that 

 they prepare their '' Extract of Australian Wattle " from the flowers of this 

 wattle, which is grown in enormous quantities on the Riviera in southern 

 Europe for decorative purposies. 



Bar!,-. — Some specimens of bark from Quiedong, Bombala, N.S.W., yielded 

 the author 21-2^ per cent, of tannic acid, and 39-36 per cent, of extract. 

 They were from trees 12 to 18 inches in diameter and 20 to 30 feet high, 

 and were grown on limestone country. A second sample from the same 

 district gave 171 per cent, of tannic acid, and 39-3 per cent, of extract. 

 They were apparently from an old tree. The barks form a rather fibrous 

 powder. 



I have examined a sample from the Delegate Eiver, N.S.W., where the 

 trees are growing- in the brush (rich jungle), in chocolate soil, attaining a 

 height of 60 to 100 feet, with a diameter of 1 to 2 feet. Bark collected in 

 April, 1889, yielded the following April 25-9 per cent, of tannic acid, and 

 4.5-Y per cent, of extract. This has the general appearance of A. decurrens 

 bark, but is in layers, separable vnth a little difficulty, more fibrous, and has 

 the appearance of having been d.usted on the outside with a white powder. 

 The whitish appearance does not rub ofE, and the stem looks as if it had had 

 a coat of lime-wash. It is the work of a lichen. 



A perfectly smooth, thin, silvery or ash-grey bark, from near Penrith, 

 N.S.W., gave 24- 13 per cent, of tannic acid, and 47-85 per cent, of extract. 



Barks received from Mr. C. Brownrigg, gathered in June, and obtained 

 from parish of Beaufort, Cowra district, diameter of tree 10 inches, yielded 

 lC-5 per cent, of tannic acid, and 42-4 per cent, of extract. A second sample 

 from the parish of Calout, in the same district, from a tree 7 inches in 

 diameter, gave 20-3 per cent, of tannic acidi, with 43 per cent, of extract. 

 Mr. Brownrigg kindly furnished the following notes with these samples: — 

 Beauforf sample—" Extensive forests of good, sound, old and young trees, 

 not affected by the ringbarking of other timber." Calout sample — " Since 

 the ringbarking' of the box and other timber, nearly all the old wattle-trees 

 iave died away ; a young forest appears to be growing up." 



Bark from county Auckland (Monaro), and stripped in November, gave 

 24 per cent, of tannic acid, and 42-55 per cent, of extract. 



Two samiples from the Cooma district gave 24 per cent, of tannic acid, 

 with 49-0 per cent, of extract, and 25-5 per cent, of tannic acid, -withi 

 51-2 per cent, of extract, respectively. The latter bark is worthy of special 

 mention. It is quite black, having not a trace of the whitish appearance 

 generally found on the bark of this sjieeies. It wfts brought to me as 

 Green Wattle {Acacia decurrens, var. mollis), and there seemed no necessity 

 to doubt the diagnosis. No expert could have told the difference between 

 it and Green Wattle if he had not been permitted to test it. It is a good 

 instance of the deceptiveness of appearances. 



" Silver Wattle " bark may be assumed to contain about 23 per cent, of 

 tannic acid in the best samples. 



In Tasmania the destruction of these trees has often been recommended 

 in ordicr to let var. mollis gro-vF, and this advice is probably sound, but only 

 in cases in which one or other has to be sacrificed.
