G24 SPECIES OF EUCALYPTS FIRST KNOWN IN EUROPE, 



other Eucalypts look sickly." 0£ the identity of this species 

 with that described by Smith there can be no doubt whatever. 



2. IJ. pihclaris, (Sm. Act. Soc. Linn., Lond., 3, p. 38i). 0£ 

 this species, the following was the original description : " Ji!. 

 ojjerciiJo conico medio constricto Jonrjitudine calycis umhellis later- 

 alihus, fritctu f/lohoso, folils lineari-lanceolatis.'^ This tree is now 

 ascertained to be that commonly called " Black-butt," but as the 

 description is applicable to other species, differing altogether in 

 the texture of the bark and the shape of the anther, we need not 

 be surprised that until very lately the specific name has been 

 applied to Stringy Bark and Grrey Grum, or that the White 

 Mahogany {E. acmenoides, Schau.) has been amalgamated with 

 it. In the writings of Baron Mueller (Fragmenta, Vol. 2, p. Gl.) 

 the Black-butt is described under the names of JE. semicorticata 

 and E. persicifolia, whilst, according to Mr. Bentham, De 

 Oandolle confounded it with E. siderojyldoia, or the Broad-leaved 

 Ironbark. Since the publication of the third volume of our 

 Plora, E. ijilularis has been identified as the Black-butt, but as 

 Baron Mueller observes in the third Decade of the Eucahjpto- 

 fjra/pliia, the name is not happily chosen. There appears to have 

 been some confusion about the specific name, for White's figure 

 a^nd Smith's description apply in some respects to the Pepper- 

 mint {E. pijyerita), the fruit of the latter being more pilular than 

 that of the Black-butt ; but there can be no doubt that the scent 

 of the leaves and the volatile oil made from them by the earliest 

 Colonists induced Dr. AVhite and others to call _27. ^ji/jenY^ the 

 ^' Peppermint-tree." though, as Baron Mueller observes the 

 popular name is now given to other species especially E. 

 amygdalina, a tree unknown in the days of White, and not 

 occurring near Sydney. 



3. E. tereticornis, (Sm. Act. Soc. Linn., Lond., 3, p. 281). The 

 typical form of this species which has obtained in different 

 districts the names of Grrey Grum, Bed Grum, Blue Gum, and
