An interesting Pulten?ea was also collected on this area. With 

 its fine leaves and yellow flowers, it presents the general facies 

 of Dillwynia ericifolia, Sm., but on inspection it is seen to be 

 covered with fine stipules, the presence of which separates it 

 from the latter genus, and it may turn out to be a new species. 

 ►Specimens are in the National Herbarium, Sydney. 



The well-known Hardenbergia {Kennedy a) monophylUt or False 

 Sarsaparilla was also noticed. This pretty purple-flowering, 

 twining plant is very common in the coastal area, being often a 

 mass of bloom in the Spring on the sides of the railway line 

 between Sydney and Gosford ; but it is not plentiful in the 

 interior, consequently its occurrence on this sandy area is of 

 interest in showing some connection between the eastern and 

 western floras, which may be traceable to a similarity of geological 

 formation. 



Acacia yladilforniis was recognised by its one-nerved linear- 

 lanceolate phyllodia, always curving gently upwards and having 

 from about 2-5 glands on the upper edge. 



A. Oswaldb was noticed at intervals with its fairly straight 

 tough little stems and somewhat umbrella-shaped head. In this 

 district it is often known as Milld}^ or Miljee, which is said to 

 be an aboriginal name, but in many places between the Bogan 

 and Lachlan it is called Dead Finish, though this name appears 

 to properly belong to a Queensland shrub, Albizzia basaltica, 

 Benth. 



It was noticed that Gassy tha glabella, R.Br., was parasitic on 

 Melaleuca nucinata; and in the Mallee scrubs around Wyalong 

 the latter plant is also the host of a species of Cassytha. 



The general result of the observations may be summarised as 

 follows : —Starting at Orange, at an elevation of about 3000 feet 

 above sea-level, we are among much of the cold country flora, but 

 during the descent of 2000 feet to Welliuiiton a complete change 

 takes place, and a diff'erent class of vegetation is found towards 

 Dubbo and Gilgandra. The chief influence regulating this 

 change is climatic, and this is also afiected by a decreasing rain-
