RANGE. 



The typical form is restricted, so far as is known at present, to the neighbourhood 

 of Port Jackson and of the National Park (a few miles to the south). The most 

 northerly locality known to me is Berowra (R. H. Cambage). 



Yariety altior. 



Found in the valleys or on the taluses of the hills of the Blue Mountain Range, 

 from Springwood higher. Also at Mount Warning, near the Queensland border, at an 

 altitude of over 3,000 feet (W. Forsyth). A tree there of 30-40 feet. So far. I do not 

 know any connecting localities; these should be looked for. 



AFFINITIES. 



Compared with E. virgata and its forms, E. Luehnanniana has broad juvenile 

 foliage. This has enabled me to submit a scheme for the separation of the two species. 

 At the same time the two species are closely related and have more than one point of 

 clos.e approach, if not of actual contact. E. virgata (the typical form), for example, is very 

 close to E. Luehmanniana, and the synonymy of the two species shows how different 

 botanists have been impressed with the closeness of the relations between them. 

 Nevertheless, in my view, there is a distinct line of cleavage between them. 



1. With E. virgata, Sieb., vaT.fraxinoides, Maiden. 



This tree resembles var. fraxinoides somewhat in general appearance (except 

 as regards the occasional blotchiness of its bark), in timber, buds, and inflorescence, 

 but the fruits are very different. 



2. With E. Sieberiana, F.v.M. 



This variety has a good deal of affinity with E. Sieberiana. This is shown in 

 the seedlings, and, to a less extent, in the fruits and timber. The bark (hard and dark 

 in the case of E. Sieberiana) would prevent the two trees, when of any size, from being 

 confused with each other. 



3. With E. obliqua, L'Her. 



These two trees have a good deal in common. The bark of E. olliqua is, 

 however, fibrous, and its fi'uits different in shape.
