NOTES ON ACACIA. Hi 



Mueller's "Iconography of Australian Acacias" does 

 not help us in regard to the position of A. oligoneura, for 

 he does not figure it, while his plate of A. delibrata is not 

 that species, see p. 86. 



The numbered specimens in the original description are 

 not available, and most of them are doubtfully attributed 

 to A. delibrata. When discovered, the material must be 

 closely compared with that of A. delibrata A. Ounn. I am 

 of opinion that A. oligoneura is too uncertain a species to 

 deal with in the present state of our knowledge, and it 

 may perhaps have to be abandoned. I should be very 

 grateful for a sight of material attributed to A. oligoneura.
