A LIST OF EXOTIC TREE8 AND SHRUBS AFFECTED 

 BY AUSTRALIAN LORANTHS AND VISCUMS. 



By Fred. Turner, F.L.S., &c. 



It is now some years since I began to make observations on 

 exotic trees and shrubs which have become hosts for certain Aus- 

 tralian parasitical plants. 



During the past year I have had peculiar facilities for making- 

 extended observations, having travelled nearly all over the Colony ; 

 and for a great part of that time I was engaged in reporting on 

 the capabilities of Crown lands, and the best means of utilising 

 them, for the Government of New South Wales. 



I am not aware that any observations have hitherto been 

 j)ublished on this subject in New South Wales. Therefore I have 

 written this paper with a view to placing on record such exotic 

 trees and shrubs as I have seen the indigenous parasitical plants 

 growing upon, so that persons who are interested in the subject 

 may be induced to make new observations. 



Although I have recorded twenty-seven species, besides numerous 

 varieties of exotic trees and shrubs which are hosts for certain 

 Australian parasitical plants, it must not be thought that the 

 list is exhaustive. What appears to me to be very remarkable is 

 the great dissimilarity between the exotics upon which Australian 

 parasitical plants have established themselves. 



In the coastal districts, as far as my observations go, it would 

 appear that exotic trees and shrubs are more infested with 

 indigenous parasitical plants than in the interior. This, however, 

 is, I think, easily accounted for. Orchards and gardens have not 

 only been longer established in the coastal districts than in the 

 interior, but the number of exotics, in proportion to the indigenous 

 vegetation, is much greater in the former than in the latter 

 portion of the Colony.
