614 ON KINGS AS AN AID IN THE DIAGNOSIS OF EUCALYPTS, 



Eucalyptus h^emastoma, Smith, B.Fl. iii. 212. 



Found in Tasmania, Victoria, N. S. Wales and Queensland. 



The specific gravity of a sample of Queensland Kino from this 

 species is about 1*378, and the percentage of tannin 64*51, 

 according to Mr. Staiger. 



13. Rough or Small-leaved" Stringybark." Lyttelton (Colombo), 

 Candelo, KS.W., 24th December, 1886. Height, 40-60 ft. ; diam., 

 2 ft. 



When freshly exuded this Kino is of a clear light ruby colour, 

 becoming more or less opaque and of a Vandyke brown colour, 

 like other ruby Kinos, if it remains sufficiently long on the trees. 

 It is clean to handle, powders fairly readily, forming a light 

 purplish-brown powder. In cold water it forms medium ruby- 

 coloured liquid. Colour of residue Vandyke brown. 



Kino-tannic acid, 57*35 per cent. ; insoluble phlobaphenes, 11*4 

 per cent. ; soluble in cold water, 88*0 per cent. 



14. Keceived from Mr. F. M. Bailey, Government Botanist of 

 Queensland, 28th February, 1888, but no particulars are available. 

 It is in rather larger and more rounded pieces than the sample 

 from Colombo, and has evidently been collected for a longer 

 period than the former. It is bright-looking, and of such a deep 

 garnet colour as to be almost opaque. 



To cold water it yields a solution of a medium ruby colour with 

 a little brown in it. Besidue Vandyke brown. 



Kino-tannic acid, 59*92 percent. ; insoluble phlobaphenes 11-76 

 percent. ; soluble in cold water, 87*8 percent. 



Eucalyptus macrorrhyncha, F.v.M., B.Fl. iii. 207. 

 Found in Victoria and N. S. Wales. 



15. "Stringybark." Amboyne, Delegate, N.S.W., 25th May, 

 1887. Height, 80-120 ft. ; diam., 2-4 ft. 



Of a rich ruby colour. This particular sample is rather friable, 

 and for this reason appears of a dull colour, unless it has been very 

 little handled. It reminds one somewhat of some specimens of 

 seed-lac.
