22. Acacia vestita, Ker., N.O. Leguminosse, B. Fl. ii., 375. 



Found in the Southern portion of New South Wales, and 



recently in Northern Victoria. 

 I know of no vernacular name for this Wattle. 

 Locality whence this particular specimen was obtained — 



Quiedong, near Bombala, N.S.W. 

 Geological Formation — Limestone. 

 Part of the Tree Examined — Bark. 

 Particulars of the trees whence it was obtained — Height 20 



to 25 feet, diameter 10 to 18 inches. 

 Collected 9th April, 1887. Analysed 5th to 13th July, 1887. 

 Very similar in appearance to the well-known bark of A. 

 decurrens, being only a little lighter in colour, and having the 

 inner bark redder. Average thickness J inch. Affords a flesh- 

 coloured powder. Forms a solution of an exceedingly rich, deep 

 red colour. The extract contains so great a quantity of colouring 

 matter as to clog the filter-paper during the operation of filtering, 

 making this one of the most tedious of Acacias to subject to that 

 operation. - '
