260 ON SOME N S.W. TAN-SUBSTANCES. 



length 94 mm., average breadth 4-75 mm. They form a powder 

 of a dirty sage-green tint. 



Extract. — -They dissolve in water to the extent of 23-22 per cent., 

 yielding a solution of a light ruby colour ; colour of moist residue 

 light brown. 



C cited lu-tannic acid — 3 '38 2 per cent. 



■57. Acacia longifolia, Willd., N.O. Leguminosse, B. Fl. ii., 397. 

 Figured in Part 6 Brown's " Forest Flora of S.A." and 

 Tab. 1828 Curtis' Bot. Mag. 

 Found in all the Colonies except Western Australia. 

 Vernacular Name — "Golden Wattle." 

 Locality whence this particular specimen was obtained — 



Cambewarra. 

 Geological Formation — Sandstone. 

 Part of the Tree Examined — Leaves. 

 Particulars of the trees whence they were obtained — Height 



12 to 15 feet, diameter 4 to 6 inches. 

 Collected 20th August, 188G. Analysed 12th to 17th 

 November, 1887. 



Phyllodia from broadly oblong to oblong-lanceolate or linear, 

 very obtuse or almost acuminate, usually narrowed towards the 

 base, with 2 to 5 more or less prominent longitudinal nerves, and 

 conspicuously or faintly reticulate between them, varying in 

 length from 2 to 3 inches in some varieties, to 5 or 6 inches in 

 others. (B. Fl.) This wattle was in flower when the leaves 

 (phyllodia) were taken. Average length 159*25 mm., average 

 breadth 9 mm. These leaves have lost much of their fresh 

 appearance in drying. In powder they afford a sage-green tint 

 rather darker than that of A. melanoxylon. 



Extract. — They dissolve in water to the extent of 21*55 per cent., 

 yielding a solution of a dark orange colour, and a moist residue 

 of different shades of brown. The extract of these leaves is very 

 •difiicult to filter. 



Catecliu-tannic acid — 1*932 per cent.

Found in Victoria, New South Wales, and Queensland. 



Vernacular Name — " Myall." 



Locality whence these particular specimens were obtained — 



Quiedong, near Bombala.
