THE EXAMINATION OF KINOS AS AN AID 

 IN THE DIAGNOSIS OF EUCALYPTS. 



PART II.— THE GUMMY GROUP. 



By J. H. Maiden, F.L.S., F.C.S. 



In Part i. (this Journal, p. 605), I showed that Eucalyptus Kinos 

 entirely soluble in both water and alcohol belong to the Renan- 

 therse, with but one exception. All such Kinos, with certain 

 members of a group yet to be described, satisfy the requirements 

 of the "British Pharmacopoeia" in regard to Kino,* and the 

 importation of a single ounce of that drug is unnecessary. 



I mentioned in that paper that certain Kinos while readily 

 soluble in water, are very imperfectly soluble in alcohol, owing to 

 the gum they contain. I ventured to call such Kinos the " Gummy" 

 group, which if not elegant is a characteristic designation, as in all 

 other Kinos gum is absent. 



Up to the present, I find that the following Eucalyptus Kinos 

 belong to this group : — 



1. E. sidero2?hloia, Benth. 



2. E. paniculata, Sm. 



3. E. crebra, F.v.M. 



4. E. leucoxylon, F.v.M. (Syn. E. sideroxylo7i, A. Cunn.) 



5. E. resinifera, Sm. , 



6. E. robusta, Sm. 



7. E. saligna, Sm.
