EUCALYPTUS SALIGNA. 



The brief diagnosis, offered by Sir James Smitb, did not admit of recognizing fully the 

 extent of variability of either E. saligna or E. resinifera ; thus arose many years ago E. bemi- 

 lampra, referred by Bentham to the latter species, but according to the smoothness of the stem 

 referable to E. saligna. This variety produces flowers on long stalklets and an elongated lid like 

 that of E. tereticornis. The differences between E. saligna and E. botryoides are habitually very 

 great on account of their respective bark, thin, smooth and pale in the one, thick, rough and dark 

 in the other ; but the characteristics of the flowers and fruits are far less marked, being almost 

 reduced in. E. botryoides to a shorter and blunter lid, an usually more angular tube of the calyx 

 and retracted totally enclosed valves of the fruit. Thus the Blue Gum-tree of the Brisbane-River 

 is not E. botryoides but E. saligna. Bees are fond of the flowers of this particular Eucalypt, as 

 indeed of those of many other congeners. The unreliability of the colonial names for most of our 

 timber-trees is again glaringly demonstrated in this instance ; and if a particular not general 

 aboriginal name could be ascertained for this species, it would certainly be deserving of preference. 

 The comparative ratio of growth of this tree should be noted, with a view of learning, whether it 

 would be recommendable as one for forest-culture, with the prospect of early remunerative gain.
