It will be observed, in the above list, that the species and 

 varieties arranged under the Order Rosacem furnish more host 

 plants than do the species and varieties arranged under any other 

 Order. I do not take this as an indication that Australian 

 parasitical plants prefer, or grow better upon. Rosaceous plants 

 than upon those that are arranged under any other Order. I 

 would rather look at it from a different stand-point. W^hen it is 

 taken into consideration that the greater number of orchards in 

 New South Wales are planted with Rosaceous trees, and that 

 many Australian birds are so fond of the fruits which they bear, 

 I think that the feathered tribe, as I have already explained, is 

 the principal cause of so many Rosaceous trees being infested 

 with Australian parasitical plants.
