BOTANICAL, TOPOGRAPHICAL AND GEOLOGICAL NOTES. 129 



series of mile-marks between Sydney and Bathurst. This 

 is also a well-defined botanical boundary, for we have 

 hitherto been traversing the sandstone, with its showy flora; 

 we now (at Oox's River) get on to the granite with its 

 larger trees (except in the sandstone gullies), and very much 

 sparser flora. Let Allan Cunningham speak : 



" Here was observed the very remarkable change of country, 

 differing from that on the mountains both in the vegetable pro- 

 ductions and nature of soil. The Banksia serrata ceases to exist 

 further westerly than the summit of Mount York, and B. compar 

 (B. marginata, is really meant), succeeds, throughout the Vale 

 (Clwydd). Eucalyptus perfoliata of Kew Gardens is very frequent, 

 and another species with cordate sessile leaves, and others lanceo- 

 late and inserted on a petiole." (Doubtless E. dives and E. Gunnii 

 var. rubida are referred to). 



He collected freely in the Vale and at five miles (from 

 Mount York) arrived at Oox's River. "About three miles 

 to the westward of Cox's River, where is a depot and store- 

 house, three remarkable hills present themselves connected 

 together. The Governor has called them Mount Blaxland, 

 Went worth's Sugar Loaf and Lawson's Sugar Loaf." It 

 is about Cox's River and Mount Blaxland that Cunningham 

 made perhaps the most interesting collections and most 

 detailed botanical notes between Sydney and Bathurst. 

 They are dealt with in his Journal, and some of his scientific 

 results are published in a volume 1 which is of especial 

 interest to our members, since it contains the only records 

 we possess of the Proceedings of the Philosophical Society 

 of Australasia (founded in 1821), of which our Society is 

 the lineal successor.

 Practically the whole of the plants enumerated by Allan Cunningham in 

 this work as having been collected by him along the route referred to in 

 the present paper were collected by us and are now in the National 

 Herbarium, Sydney.
