450 NOTES ON NATIVE FLORA OF NEW SOUTH WALES, V., 



of this species in the locality in spite of some adverse conditions,, 

 affords a splendid example of the influence of shelter, warmth 

 and moisture. 



Of the western plants whi ch were found near the Wollondilly, 

 the most interesting were Eucalyptus a/bens, Casuarina striata, 

 and Myoporum deserti. Associated with these was Eucalyptus 

 melliodora, and the same four species may be seen at Mt. 

 McDonald, near the Lachlan River, and other western spots. 



As E. melliodora, the Yellow Box, is one of the most amenable 

 to climate of the genus, ranging from the heat of the Lower 

 Lachlan up to elevations of 3000 feet above sea-level in latitudes 

 south of Bathurst, and up to about 4000 feet on New England, its 

 occurrence on both sides of the Main Divide is not remarkable 

 as in places where it crosses, the highest points are less than 

 3000 feet. 



The case of Myoporum deserti is somewhat different, and 

 although it has been recorded from all the States on the main- 

 land, it is usually confined to the western watershed in New 

 South Wales. It is well known, however, that many western 

 plants cross the lower parts of the Liverpool Range and follow 

 down the valley of the Hunter River to the vicinity of Singleton,. 

 M. deserti being one of these. Mr. R. T. Baker* has recorded 

 numerous western forms on the upper part of the Goulburn 

 River, a tributary of the Hunter, but the numbers become less 

 as the valley is descended, and eastern influence is encountered. 

 The wide distribution of M. deserti is somewhat suggestive of 

 antiquity, though its seeds are of such form as to assist dispersal 

 by birds. 



Casuarina stricta(8heosik) belongs to the interior and southern 

 parts of Australia, coming up along the eastern coast of New 

 South Wales as far north as Newport, near Sydney, where it is 

 confined chiefly to within a few miles of the ocean. It is another 

 of the western trees which is found in the Hunter valley as far 

 down as Singleton. In these Proceedings, 1905, p. 376, 1 suggested
