WATTLES AND WATTLE-BARES. 47 



23. Acacia subporosa, P. v. M. (supporosa in Muell., Eragm. 

 iv., 5), B.EL, ii, 382. 



" RIVER WATTLE." 



A sample of bark from a Victorian locality yielded Baron Mueller 6*8 per 

 cent, of tannic acid, and 1/2 per cent of gallic acid. (Cat. Technological 

 Museum, Melbourne). 



A sample from Colombo, Candelo, N.S.W., was collected in June, 1889, 

 and analysed by me April, 1890. It is a smooth, thin, fibrous, light-coloured 

 bark, strongly resembling that of A. longifolia. It is from trees 20 to 30 

 feet in height, and with diameters of 6 to 15 inches. It was grown in granite 

 country. My analysis gave 6'6 per cent, of tannic acid, and 22'55 per cent, 

 of extract, peculiarly coincident with the determination already given. I may 

 mention that I have made determinations of gallic acid and impurities in all 

 my analyses, and I shall be happy to give particulars in the case of individual 

 barks to anyone who applies for them. They are not of sufficient practical 

 importance to Australian tanners to print here. In this particular instance 

 my determination of gallic acid was 1/16 per cent. 



Pound in coast districts in New South "Wales and Victoria, on the banks 

 of creeks and rivers. Its most northern extension for New South Wales 

 appears to be the Shoalhaven River. 



24. Acacia homalophylla, A. Cunn., B.EL, ii, 3S3. 



' 'CURLY or NARROW-LEAVED YARR AN." A "Myall." Called also " Gidgee." 

 A specimen of this bark gave the following result : Tannic acid, 9'06 per 

 cent., and extract, 21'51 per cent. (Proc. JR.S., N.S.W., 1887, p. 189.) 



It was from an old tree, full of flakes, and could be pulled to pieces with 

 the fingers. A dry-country bark, but hardly a fair specimen of that. Found 

 in the interior of South Australia, Victoria, New South Wales, and Queens- 

 laud. 



25. Acacia pendula, A. Cunn., B.EL, ii, 383. 



" BASTARD GIDGEE" or " NILYAH." Usually known as "Myall." 

 A sample of this bark from Yandarlo, "VVilcanuia, afforded the author 

 (Proc. E.S., N.S.W., 1888, p. 269) 3'25 per cent, of tannic acid, and 14/52 

 per cent, of extract. Height of tree, 10 to 12 feet ; diameter, 4 to 6 inches ; 

 collected September, 1887 ; analysed August, 1888. A typical representative 

 of the dry-country wattle barks. It seems to consist of nothing but flakes 

 and layers of fibre. 



An inland and desert species of New South "Wales and Queensland.
