Forest Guard Gr. J. Hampstead finds it in the vicinity of Macpherson Range 

 (Queensland border), reporting it from between Wallaby Creek and Koreelah Range, 

 County of Buller. 



Eastern boundary. The most south-easterly locality I have is the Queanbeyan 

 district. Here is a reminder that we are in a comparatively cold district, and that the 

 species must find out sheltered localities in which to flourish. The boundary about here 

 is probably a very irregular line. At all events, we do not know what it is. The species 

 occurs going north from Canberra to Yass, north-easterly to Wombeyan Caves and the 

 Camden district. 



3a. The Sydney Enclave. Then there is what I may term the " Sydney enclave " 

 with which we are so familiar, since so many southern plants, coming north, avoid the 

 Sydney district (roughly the County of Cumberland). This enclave of low-level country 

 is too warm for many southern species which flourish at an elevation of say 1000 to 

 2,500 feet, and they get north via the Blue Mountains or the broken country to the west 

 of them. In that way such a species as E. albens arrives at that measure of climatic 

 equilibrium which it requires. 



This " Sydney enclave " indicates the proximity of a plant-bridge, just as a 

 geocol does, but for a very different reason. The " Sydney enclave " indicates that, 

 surrounding it, there is passage of species by means of approximate continuity of high 

 land, while a geocol indicates the reverse, viz., a break or gap in the high land, through 

 which plants can pass and repass. In the former case, the migration of plants is 

 approximately north and south, in the latter case, approximately east and west. 



To resume our records of E. albens: A few miles north of Wallerawang we go 

 north to Rylstone and Barigan, and north-east to Merriwa and Scone, then more or less 

 northerly to Murrurundi, Currububula, Tarn worth to Inverell, and on to the Queensland 

 border. 



In Victoria, notes on the range are given in Part XI, p. 23. It grows in the 

 Tambo Valley between Fainting Range and Bindi, and in the Snowy River Valley. 

 Dr. A. W. Howitt also observed it in places in the north-eastern district. 



The following are the Victorian localities, and, so far as I am aware, are very 

 incomplete : — Heathcote, Bendigo, Burora, Rushworth, Rutherglen, Ovens River, 

 Tongio, Gippsland, Ensay, Tambo River. See Map 294. 



In South Australia the species is only known in the Flinders Range, a few miles 

 to the east of Port Augusta. Srjecific localities are Mount Remarkable, Laura, 

 Wirrabarra. 



Until we know more fully the range of the species in Victoria and South Australia, 

 it is obvious that we cannot construct curving boundaries for it for the whole of 

 Australia. We have already seen that we do not fully know them for New South Wales, 

 the State we know most about in this connection.
