\delegatensis) formed one grand trimorphic species. The strong 

 sweet odour of the trees of E. Risdoni var. elata in the forest 

 very closely resembles that of E. obliqua var. alpina. Some 

 Gum-top Stringybarks are undoubtedly near typical E. obliqua, 

 and this variation is consistent with the hybridisation theory, 

 since in a series of hybrids the influence of one or other of the 

 parents may predominate. 



This form alpina of obliqua is found in alpine situations in 

 Tasmania, Victoria and southern New South Wales.

Glen Elgin, about 30 miles north-easterly from Glen Innes, or 

 about 20 miles easterly from Deepwater and on the eastern 

 watershed (E. C. Andrews). 



7. E. OBLIQUA, L'Herit. 



Woollooma Mountain, Parish of Chalmers, County of Durham, 

 Land District of Scone (H. L. White). This locality is interest- 

 ing as connecting the southern localities with the northern ones.

I have seen Bonpland's exceedingly rare work, and the illus- 

 tration and description are satisfactory. Mueller (in 'Eucalypto- 

 graphia,' under E. santalifolia) gave the one as a synonym of the 

 other, yet he suppressed Bonpland's species, which had a priority 

 of 42 years over his own. I cannot understand his action, but 

 I am aware of other instances of his arbitrariness in dealing 

 with the laws of priority; he sometimes suppressed a species at 

 his own will. In the 'Eucalyptographia' he speaks of Bonpland's 

 figure, but apparently at second-hand, for the plate contains 

 juvenile foliage (a very rare thing in the earlier figures of Euca-
