AFFINITIES. 



1. With E. viminalis Labill. 



The new species has by most observers been confused with E. viminalis, and 

 being a White Gum with rough bark at butt, and growing on river flats and banks of 

 rivers explain why this view has been so prevalent. But it is more erect in habit, 

 E. viminalis having more pendulous branches and more distinctly ribbony bark. 



The new species has broader juvenile leaves, the foliage is sub-glaucous, the 

 flowers are smaller and never in threes, the fruits are of a different shape, with the 

 valves never as exsert as those of E. viminalis. 



2. With E. Macarthuri Deane and Maiden. 



E. Bentliami is a tall, rather erect tree with a somewhat thin canopy ; 

 E. Macarthuri is a smaller tree with a rather umbrageous head. The bark of 

 E. Macarthuri is rough, somewhat box-like, but very woolly, that of E. Bentliami 

 being smooth in the upper portion (a White Gum) and flaky at the base. Sometimes 

 it is wholly smooth. 



The juvenile foliage and buds are sub-glaucous in E. Bentliami; the buds of 

 E. Macarthuri are often shining and slightly smaller than those of E. Bentliami. 



The trees referred to as E. Macarthuri at Werriberri Creek in Proc. Linn. Soc. 

 N.S.W. xxxvi, 553 (1911), are E. Bentliami. Werriberri Creek is the locality better 

 known as The Oaks, near Camden.
