2. With E. saligna Sm. 



When seen in its native habitat it might easily be passed by as E. saligna Sin., but it differs frcm 

 that species in the timber, fruits and chemical constituents cf its cil, ar.d venation of the leaves. ... It 

 very possibly has been looked upon cr classed as E. saligna Sin., which is sometimes found en the banks of 

 streams near the coast, both having a similar silver-grey shining bark. (Original description.) 



The similarity in the two species is only in the general appearance of the two 

 trees and in the situations in which it grows. 



3. With E, viminalis Labill. 



Here we have another tree similar to E. oreades to the extent that E. saligna is. 



It is a typical ribbony Gum, the ribbons being 8 to 10 feet long, and even more, broad and tough. 

 We think it very probable the species has been sometimes noted as E. viminalis, judging frcm its 

 appearance as a ribbony Gum, but it is a handsomer and more erect species than E. viminalis. It is. a 

 tall tree, very straight, 60-100 feet high, and even more. It has absolutely clean, shiny stems except at 

 the butt, say for 8 or. 10 feet, where it is more or less fibrous. At Mount Wilson it is associated with 

 E. goniocalyx, and at Mount Victoria with the same species to a-less extent. (This work, IX, 289.) 



4. With E. dives Sehauer. 



In the venation of the leaves it might also be classified with E. dives Schau., but 

 in no other feature does it approach that species. (Original description.) 



5. :; The fruits are somewhat similar to those of E. striata Sieb., E. obtusiflora, 



and E.fraxinoides, but smaller." (Original description.) This is a comparison 

 based primarily on the immature fruits of E. oreades. 



This species, E. obliqua and E. fraxinoides show an affinity in the venation of 

 the leaves and in the shape of the fruits. 



6. With E. coriaeea A. Cunn. 



The venation and timber, as well as fruits and flowers, differentiate it from 

 E. coriaeea A. Cunn., although some of its chemical constituents connect it with that 

 species. In botanical sequence it is placed between E. Sieberiana F.v.M. and E. coriaeea 

 A. Cunn. (Original description.) 



7. With E. obtusiflora DC. See under E. obtusiflora, at p. 297. 



8. With E. virgata Sieb. 



In the original description of E. Luehmanniana (virgata) var. altior, Messrs. Deanc 

 and Maiden say, " A tree which may be described as a form of E. Luehmanniana, with 

 fruits and all other parts comparatively small." Here we have veritable geminate 

 species, remarkably similar. E. oreades flourishes in colder situations than does E. 

 virgata, of which it is the mountain form. The localities of the two species have been 

 ascertained to approximate very considerably, and it is very probable that the 

 (comparatively) cold tops at Kuring-gai Chase, the Penang Range, and National Park 

 (all E. virgata), will approach very closely localities for E. oreades, whose nearest points 

 are at present Hill Top gullies and Lawson gullies.
