266 AUSTRALIAN NATIVE PLANTS. 
7- Eucalyptus Baileyana, /.v.J/.; N.O., Myrtacee, F.v.M., 
Fragm. xi. 
A “ Stringybark.” 
The fresh leaves yield .goo per cent. of essential oil of .890 
specific gravity, and having an acid reaction. (Staiger.) It is 
described as having a turpentine odour. “Strongly resinified; 
sp. grt. 0.940; boils between 160° and 185°. This oil, and those 
of EZ. mtcrocorys and E. maculata, var. citriodora, are very similar 
to one another. They possess amagnificent melissa-like odour. 
It is thought they will prove to possess extraordinary practical 
value. Chemically, the three oils are quite characteristic. Neither 
of them contains a terpene, but they consist of a ketone (Cy H,O), 
smelling like melissa, and a body that is probably an alcohol 
(Cy Hs O ?), which possesses a beautiful odour resembling that of 
geranium. (Messrs. Schimmel & Co., in Pharm. Fourn., April, 
1888.) 
Near Brisbane (Queensland). 
8. Eucalyptus capitellata, Smith, N.O., Myrtacez, B.F1., iii., 206. 
“Stringybark.” (For names and synonyms, see “* Timbers.”) 
Under the name of £. piperzta, an account of this tree is 
given ina Fournal of a Voyage to New South Wales, by John 
White, Esq., Surgeon-General to the Settlement, published in 
1790. He (or rather Dr. Smith) says of it (p. 227): ‘‘ The name 
of peppermint tree has been given to this plant by Mr. White 
on account of the very great resemblance between the essential 
oil drawn from its leaves and that obtained from the Peppermint 
(Mentha piperita) which grows in England. This oil was found 
by Mr. White to be much more efficacious in removing all 
cholicky complaints than that of the English Peppermint, which 
he attributes to its being less pungent and more aromatic.” Mr. 
White sent a quart or more of the essential oil from this, or other 
Eucalyptus leaves, to England. This was the commencement of 
what is now a flourishing industry, engaged in by almost all the 
colonies, and capable of still greater expansion. 
Victoria to Queensland. 
9. Eucalyptus corymbosa, Smith, (Syn. Metrosideros gummifera,
