Divide, it attains its greatest dimensions along the eastern margin 

 of New England under a coastal, as opposed to a westerly 

 influence. This species occurs at Maryland and Stanthorpe in 

 Queensland, according to Mr. Andrews. 



Another interesting Eucalypt occurring abundantly between 

 Stanthorpe and Torrington is E. Deanei, locally called Brown 

 Gum. This is another coastal form which extends as far south 

 as Picton Lakes, where it is known as Blue Gum, giving rise to 

 the name of the creek which flows from the lake. It is found 

 on various tributaries of the Hawkesbury and Hunter, and 

 gradually ascends the eastern face of the New England plateau, 

 till towards the north it crosses to the western watershed. Its 

 noble and stately proportions, as seen along the Burragorang 

 valley in the south, where the combined conditions of warmth, 

 shelter and moisture all contribute to a luxurious growth, are 

 missing in this north-western area. Though in the north-west 

 it is still comparatively large, its exposure in a more elevated 

 climate has resulted in diminished stature, and probably also in 

 its being coated with the brown flaky bark which has suggested 

 the local name for the species. 



E. tereticornis, the Forest Red Gum so widely known over the 

 Coastal and Mountain Areas and Western Slopes, is distributed 

 over both the andesite and granite formations around Stannum. 



E. Bancrofti was not only restricted to the granite area, but 

 was practically confined to the rocky and higher parts, only 

 following to lower levels while attended by the influence of the 

 acid granite. It appears open to question whether this is a dis- 

 tinct species or merely a variety of E. tereticornis.* That it has 

 strong affinities to the latter is beyond doubt, but after carefully 

 observing both trees in various localities I am disposed to regard 

 the former as sufficiently distinct to warrant its having specific 

 rank. It seems possible that E. Bancrofti may have developed 

 in some way by environment over long ages as a form of E. tereti- 

 cornis, and by constantly selecting these somewhat elevated hard
