Eucalyptus amygdalina, LahilL, B.Fl. iii. 202 (Syn. E. fissilis, 

 F.v.M. ; E. radiata, Sieb. ; and other synonyms). 



This Eucalypt has more than a score of vernacular names, but 

 in regard to this species, as in others, only those vernacular names 

 have been used which are actually employed to describe the tree 

 in the locality given. 



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



1. E. amygdalina var. radiata. " Ribbon Gum." Nelligen, 

 Clyde River, N.S.W. Collected 21st and 22nd September, 

 1886. Height, 100-120 ft. ; diam., 2 ft. 6 in. 



A clear port- wine coloured Kino, which is fairly friable, yielding 

 a sparkling powder. It is not readily obtainable in large pieces. 

 It dissolves readily in cold water, forming a clear, medium ruby 

 liquid, but the residue contains more woody matter than the 

 Bombala sample, and less phlobaphene. Colour of residue Vandyke 

 brown. 



(Note. — Colours are taken from damp residues. The colours of 

 aqueous solutions were taken from J gram, of powdered Kino in 

 100 cc. of water, which stood for three days, and the colour esti- 

 mated by placing the liquid in a bottle 2 inches in diameter.) 



Kino-tannic acid, 62*95 per cent.; insoluble phlobaphenes, 6'46 

 per cent.; soluble in cold water, 92*54 per cent.* 



2. E. amygdalina, var. " Peppermint." Bombala, N.S.W. 

 Collected 14th Feb., 1887. Height, 60-80 ft. ; diam., 3 ft. Phy- 

 sical description same as No. 1. 



In cold water it forms a solution of a pale ruby colour. The 

 insoluble phlobaphene is very dark, almost black. Colour of 

 residue purplish-brown. 



* The remainder of these Kinos consists for the most part of hygroscopic 

 moisture (average 20 per cent. ), together with small percentages of sugar, 

 resin, &c. I have made complete analyses of them, but the descriptions of 

 the raw products themselves, and an account of the botanical questions 

 involved in the elucidation of them, can alone properly be brought before 

 this Society.
