1282 ON KINGS AS AN AID IN THE DIAGNOSIS OF EUCALYPTS, 



Sometimes the bark of this tree is honeycombed, the cavities 

 being filled with Kino. The blackish Kino, set in rows, in the 

 light reddish-brown bark, has a beaded granular appearance, cha- 

 racteristic, perhaps, of this species. 



No. 26. "Ironbark." Received from the Botanic Gardens, 

 Sydney, 29th December, 1887. 



This sample is in large masses, from which the firmly adherent 

 wood and bark have to be cut away. It is of horny appearance, 

 a,nd shows something of that texture when cut with a knife. It 

 is opaque-looking, except at fresh fractures. The Kino appears 

 almost black, and it is only at the edges of thin splinters that it 

 is observed to be of a deep garnet colour. It powders with diffi- 

 culty, forming a powder much like Indian red. 



Cold water yields a deep orange-brown solution, leaving a 

 residue consisting of phlobaphene and shavings of bark. The 

 process of solution goes on very slowly. Colour of residue Sienna 

 brown. 



Eucalyptus paniculata, Sm.^ B.Fl. iii. 211-212. 



Found in N. S. Wales, the S. Australian and Victorian species 

 being probably difierent. 



No. 27. "She Ironbark;" North Ryde, 28th April, 1888. Diam. 

 1 ft. 6 in. ; height, 60 ft. 



The tree which yielded this particular sample yielded it in 

 unusual abundance. Not only have I never seen a tree of this 

 species yield it in such quantity, but in abundance it rivalled the 

 quantity exuded by an JE. corymhosa tree in full bearing of Kino. 

 The rugged bark was covered with a mass of long tears, and 

 samples of great purity could readily be obtained. When collected, 

 this Kino resembled orange lac in appearance to a marked degree, 

 though some fragments varied in tint to brown and garnet lac. 

 In all cases the resinous appearance of the Kino is strikingly 

 similar to lac. It is fairly brittle, and forms a bright powder.
