PLANTS OF NEW SOUTH WALES, 



circumstance should have caused not only L. Scoparium (which 

 is common to New Zealand and Australia), but all its congeners 

 to be denominated Tea-trees. In Victoria the principal genera 

 of the Myrtaceso are Bceckia, Melaleuca and Eucalyptus, compre- 

 hending respectively 7, 12, and 30 species. The genus 

 Eucalyptus, of which in ' Willdenow's Species Plantarum (1799) 

 only 12 species are enumerated, is now known to have some 150 

 distinct forms, and of these, one third occur in New South 

 Wales. It is a curious fact in the distribution of plants that 

 very few species occur out of Australia. Mr. Bentham remarks : 

 "With the exception of two species extending to Timor, and 

 two or three or perhaps one single somewhat doubtful species 

 from the Indian Archipelago, the Eucalypti are all Australian." 

 Since the publication of the 3rd Vol. of the Flora Australiensis, 

 however, Baron F. von Mueller, in his Eacalyptoyrapliia (Decade 

 4.) under E. alba (Reinwardt) states that: "The number of 

 Extra-Australian species of Eucalyptus is extremely limited, so 

 far as hitherto known, although additional congeners may perhaps 

 yet be obtained from New Guinea, and even there possibly from 

 Alpine regions." He then mentions as Extra- Australian not 

 only E. alba, but also E. moluccana, (Roxb.), E. Decaisneana, 

 (Blume) and E. Papuana, recently described by himself in his 

 notes on Papuan Plants. The Baron regards the absence of 

 Eucalyptus from the vegetation of New Zealand as very remark- 

 able, and more especially as "an Eucalyptus-like tree has 

 recently been recorded from New Ireland by the Revd. W. Brown 

 as forming forests in that island." 



The following is a list of the Eucalypts indigenous in New 

 South Wales, arranged principally according to Baron Mueller's 

 cortical system.
