RANGE. 



9 



The range of this species, as far as is known at present, is remarkable. Its most 

 southerly locality is on the Monaro, a portion of the great southern table-land, at Cooma, 

 about 60 miles from the Victorian border, at an elevation of 2,700 feet. 



Proceeding north, after several hundred miles, we ascend New England reaching 

 as far as Stanthorpe in Queensland (under 3,000 feet), and also find the species in a 

 number of places on the western slopes of New England. 



Coming to the coast, the most southerly locality we have it from is Camden 

 Haven, a little south of Port Macquarie, and thence, going north, it occurs as far north 

 as Woolgoolga in the Grafton district. We do not know its north coastal range precisely, 

 and, bearing in mind the gap between the table-lands and the coast, it is quite evident 

 that we have much to learn in regard to intermediate localities. 



The matter of transition forms will be referred to below. 



New South Wales. 



Southern Tableland. — Following Cooma Creek at the back of the Gaol, Cooma, 

 " A tumble-down gum, like the same species foimd at Emmaville, Wallangaxra, &c." 

 (J. L. Boorman.) Figured at figure 1, Plate 131, with blunt opercula, and leaves. 



This locality is remarkable, as we do not know this form nearer than at least 350 

 miles to the north as the crow flies. Intervening localities, probably on mountain-tops, 

 should be looked for. 



Nortliem Tableland.—" From most exposed parts of the mountains at 1500-2000 

 feet. (N.B. — the heights were not generally known in Stuart's days, and thess figures 

 should be nearly doubled. — J.H.M.). A straggling tree, 20-30 feet, with very smooth 

 white bark, separating in thin scales." New England. (Charles Stuart, No. 127). 

 Labelled by Mueller " E. tereticornis Sm. var. amblycorys F.v.M." It is the var. brevifolia 

 of Bentham (B. Fl. iii, 242), with short, blunt leaves. 



On another specimen (No. 308) also from ("New England,. 1500 feet.') Stuart 

 wiites : " A large tree, but frequently flowering very young." The leaves are lanceolate, 

 but otherwise like No. 127. Opercvda blunt. 



The rim of the calyx in this Gum is very marked. The valves are well exserted 

 and pale. The operculum and calyx are full of oil dots. The leaves are dull, the veins 

 are finer and less prominent than that of E. tereticornis; the intramarginal vein is 

 usually not so far distant. The peduncles are much broader and flatter than in E 

 tereticornis; the pedicels likewise are broader and flatter. The operculum is sub- 

 cylindrical, much longer than the calyx, but the calyx is larger and the operculum 

 smaller than in the normal species. The operculum is narrower than the calyx, giving 

 the appearance of " egg- in -egg-cup " or acorn and cup. This shape is very marked. 

 The pedicels are flat and thick. The whole fruit is coarser in appearance than is that 

 of E. tereticornis.
