AFFINITIES. 



1 E. stellulata, Sieli. 



As already indicated, the closest relations of U. coriacea are with E. stellulata, 

 of which, in some resjiects, it strongly resembles a coarse form. 



2 E. coceifera, Hook. f. 



It seems to me that the alpine forms of E. coceifera are very close to the 

 Tasmanian E. coceifera, Hook, f., and this word of caution may he useful to the 

 student. 



3 E. vitrea, R. T. Baker, or E. vitellina, Naudin. 



In a specimen from the Blue Mountains in Herb. F. Muell. tlie leaves are long and almost linear 

 lanceolate, but very thick with the longitudinal veins of E. coriacea, of which it has also the flowers. 

 — (B.Fl. iii, 201.) 



In the above passage Bentham is doubtless speaking of specimens very 

 similar to those I have from Jenolan Caves (W. F. Blakely). They are nearest to 

 Mr. B. T. Baker's E. vitrea, though not typical. E. vitrea is, in my opinion, 

 a hybrid between E. coriacea and E. amygdalina. 



I will go into tlie matter at some length when dealing with E. amygdalina. 

 Suffice it to say, at this place, that the tree i*efcrred to in the Flora Australiensis 

 could not be confused, in the field, with E. coriacea ; the former being a rough- 

 barked tree and the latter a specially smooth gum.
