EUCALYPTUS ALBA. 



(or White-tree), and that the tree can be grown on the plains of Java, where most other Eucalypts 

 will not succeed. It is never a very tall tree and begins to flower already in the third year of 

 growth. It may be added, that the bark of E. tectifica and allied Australian species is not 

 lamellar like that of Melaleuca Leucadendron. The absence of Eucalypts in the native vegetation 

 of New Zealand is under these circumstances all the more remarkable, though certainly a vast 

 proportion of the flora of those islands is endemic. But an Eucalyptus-like tree has recently been 

 recorded from New Ireland by the Rev. Mr. Brown as forming forests in that island. 



This, like all other Eucalypts, passes in vernacular language as a " Gum-tree," an 

 objectionable appellation, which should be banished and superseded by that of " Eucalypts," as 

 first insisted on by the writer. The name " Gum-trees " would indeed be far better applicable to 

 our native Acacias, which exude real gum as understood in chemical science and is quite 

 identical with Gum Arabic, whereas the exudations of Eucalypts must be classed with the various 

 kinds of Kino.
