EY THE REY. DR. WOOLLS, D.D., F.L.S. 629' 



is difficult to say whether Smith's description applies to the true 

 White Grum or the half-barked tree with similar flowers and fruit 

 which is frequentlj^ associated with it, but, following the description 

 and figures of the Hiicahjptograpliia^ we cannot err in restricting 

 the term licemastoma to the smooth tree, and Sieheriana to the 

 half-barked one. They are, according to the artificial system, 

 closely allied, though the texture of the bark places them in 

 different sections. 



9. E. piperita (Sm , Act. Soc. Linn., London., 3, p. 2S6; Smith's 

 Xov. Holl., J2 ; AV^hite's itin., 226, c. icone.) The description of 

 this species, though common in the neighbourhood of Sydney 

 and Parraniatta, is so vague and imperfect that it has been applied 

 to " Blue Gum," and " Stringy Bark," as well as to the " Pepper- 

 mint" which ir was originally intended to designate : " H. opercuJo 

 hcsmispli(srico mucronuJcdo, umheUis JatcraUbus suhpaniculatis 

 solifariisve, peduncuUs compressis, ramidis anrjulatk foliis ovatis 

 licet ohJiqua sint.^' AVithout reference to the original specimens 

 or the figure given by Baron Mueller, it would be impossible to 

 determine the species indicated by Smith, and, even in the latter, 

 the scabrous seedling of a Stringy Bark is incorrectly associated 

 w^ith it. Mr. Bentham, judging from the dry material before 

 him, supposed that the Peppermint was a variety of Stringy 

 Bark, but independently of the fact that the respective nature of 

 their bark places them in separate sections, there is a marked 

 difference in the shape of the leaves and fruit. It may now be 

 considered as certain that Smith's E. piperita is the Peppermint 

 growing near Sydney, the leaves of which yield an oil resembling 

 Peppermint in scent. There are now other trees called by the 

 same name {E. JongifoJia or the "Woolly Butt, and E. dealhata on 

 the other side of the Dividing Eange), but at the period when. 

 White forwarded his specimens to Europe these species w^ere- 

 unknown, and the only tree from which the colonist extracted. 

 the so-called Peppermint oil was E. piperita.
