52 WATTLES AND WATTLE-BARKS. 



Sob. A second variety of A. longifolia,' viz., floribunda, obtained from 

 Cambewarra in August, 1886, yielded the following result in April, 1890: 

 Tannic acid, 6'09 per cent. ; extract, 14'95 per cent. It was from trees 20 

 to 50 feet high, locally known as " Sally," or "Sallow." 3 he bark is very 

 like that of the normal species, but from an older tree, and also full of fibre. 

 A specimen of " Sally " from Bolong Swamp, Nowra, collected in July, 1888, 

 and analysed also in April, 1800, gave only 2'54 per cent, of tannic acid, with 

 13'07 per cent, of extract. It is a useless, fibrous bark, yielding a substance 

 like chopped grass when passed through the mill. It was from trees 20 to 

 40 feet high, with diameter of 6 to 18 inches, and grown on alluvial soil 

 which the species in general usually favours. 



36. Acacia aneura, E. v. M., B.M., ii, 402. 



" MULGA." The chief ingredient of Mulga scrub, so called from the Mulga, or long, 

 narrow shield of wood made by the aboriginals out of Acacia wood. 







A specimen of the bark of this tree from Ivanhoe,tuVz Hay, 1ST.S.W., yielded 

 478 per cent, of tannic acid, and 10 per cent, of extract. A narrow-leaved 

 variety from the same neighbourhood yielded 20*72 per cent, of extract, 

 and 8'G2 per cent, of tannic acid. The former is a deeply-furrowed, flaky, 

 pulverulent bark, apparently from an old tree ; average thickness, -jj- inch. 

 The bark of the narrow-leaved variety is a thin, poor bark, not exceeding 

 i : * G inch in thickness, moderately fissured, of a dark-grey colour, sometimes 

 nearly black. (Proc. R.S., N.S.W., 1887, p. 32.) 



A second sample of the normal species gave {Proc. R.S., N.S.W., 1888, 

 p. 271), 2'32 per cent, of tannic acid, and 12'12 per cent, of extract. 

 It was from Tarella, Wilcannia; collected August, 1887; analysed August 

 1888. A useless, flaky, dry-country bark. 



An inland, desert species, found in all the colonies except Tasmania. 



37. Acacia glaucescens, Willd., B.FL, ii, 91. 



A "MYALL" and "BOREE" of Southern N.S.W. Called also "BRIGALOW," 



"ROSEWOOD," &c. 



Bark from near Bombala, N.S.W., yielded 810 per cent, of tannic acid, 

 and 14'29 per cent, of extract. (Proc., R.S., N.S.W., 1887, p. 91.) It was 

 locally termed " Myall," and was grown on limestone. Height, 20 to 25 

 feet ; diameter, 6 to 12 inches. A deeply fissured bark of a dark-grey 

 colour. I would like to get better samples of this bark. 



From Victoria to Queensland ;^a favourite situation being high river banks 

 amongst rocks.
