ON SOME N.S.W. TAN-SUBSTANCBS. 



Particulars of the trees whence they were obtained — Height 



60 to 80 feet, diameter 3 feet. 

 Collected 14th February, 1887. Analysed 24th October to 

 24th November, 1887. 

 These leaves are as different from the previous variety as it 

 is possible for Eucalyptus leaves to be. They are lanceolate to 

 nearly ovate, are slightly inequilateral, and have very prominent 

 oil-dots. The tree was in flower-bud when they were gathered. 

 They are deliciously aromatic, more so than the previous variety, 

 but they have been better dried than those leaves. Average 

 length 90-25 mm., average breadth 26*6 mm. They yield a 

 greenish powder containing a certain excess of yellow, — " quaker 

 green." 



Extract. — They yield 44*24 per cent, to water at 100° C. Colour 

 of extract light yellow, slightly turbid, and of moist residue dark 

 drab. 



Kino-tannic acid — 8*75 per cent.

 204. Figured in Brown's "Forest Flora of S.A." (Part i.), 

 Dec. 3, " Eucalyptographia," 

 Found in South Australia, Tasmania, Victoria, and New 



South \Vales. 

 Vernacular Name — -" Stringybark." 

 Locality whence these particular specimens were obtained — 



Cambewarra. 

 Geological Formation — Sandstone. 

 Part of the Tree Examined — Leaves. 

 Particulars of the trees whence they were obtained — Height 



60 to 80 feet ; diameter 2 feet. 

 Collected 30th August, 1886. Analysed 12th to 17th 

 November, 1887. 

 Leaves scattered, sickle-shaped or sometimes oval-lanceolar,

 , removed from the edge, oil-clots concealed. (Eucalyptographia.) 

 Leaves in the usual form mostly oval-]anceo]ate, falcate and 

 very oblique at the base, more or less acuminate, 4 to 6 inches 

 long, thick with very oblique distant anastomosing veins, the 

 intramarginal one at some distance from the edge. (B. Fl.) 



Average length 159 mm., average breadth 35 mm. They yield 

 a powder of a sage-green tint. 



Extract, — They yield 41*13 per cent, to water at 100° C. Colour 

 ©f extract rnby, and of moist residue light yellowish brown. 

 Kino-tannic acid — 17*2 per cent.
