As regards the leaves, the table-lands specimens are in their typical form (var. 

 brevifolia, Benth., New England) short and blunt, though with some tendency to be 

 lanceolate, and in a number of the tablelands specimens lanceolate leaves are common, 

 though the general tendency is to be short. 



In the coastal specimens the leaves are uniformly lanceolate, and in some cases 

 very long {e.g., Woolgoolga). 



So that we have : — 



1. Blunt opercula and blunt short leaves 2-3 inches long (E. tereticomis var. 

 brevifolia) from New England and elsewhere. 



2. Blunt opercula and long leaves (6-7 inches) . (Orange Gum of Port Macquarie, 

 type of E. Bancroft i) ; also Woolgoolga up to 12 inches. 



3. Long opercula and leaves intermediate in length {e.g., Emrnaville). 



Other instances of variation can be cited from the specimens about to be 

 enumerated, and also from Plates 129-131. 



Examination was made to see if the table-lands specimens constituted a form 

 distinct from that of the coast, but the distinctions hardly seem sufficiently marked. 



E. Bancrofti, over all its range, whether on the granite of New England and the 

 Monaro, or in coastal swamps, is a depauperate tree usually described as " Tumble- 

 Down Gum." In the former localities it is a denizen of hungry soil, in the latter the 

 bog-water, often ferruginous, is physiologically unsatisfying. It is a form, therefore, 

 that has accommodated itself to very hard conditions, and variation has been stimulated.
