NOTES ON THE NATIVE FLORA OF NEW SOUTH 

 WALES. 



By R. H. Cam bag e. 



Part iii. Orange to Dubbo and Gilgandra. 



(Plates ii.-iii.) 



These notes are the result of observations made at various 

 periods, but the most of them were taken in October, 1904, those 

 referring to parts of the country between Orange and Dubbo 

 being made from the train. At Dubbo various plants were 

 collected, but from there to Gilgandra the notes refer to the 

 country in the vicinity of the railway line, while a further 

 collection was made in the latter district. As no detailed 

 examination of the country was possible, it follows that many of 

 the smaller plants have been overlooked, but the appended lists 

 are sufficient to convey an impression of the general character of 

 the tiora over the area described. 



The altitude of the country around Orange is about 3000 feet 

 above sea-level, while at Wellington it has fallen to lOUO feet, 

 and at Dubbo and Gilgandra the heights at the railway stations 

 are 867 and 942 feet respectively. The climatic influence on the 

 vegetation is evident owing to this change in altitude, with its 

 corresponding difference in rainfall, the higher country around 

 Orange having an annual rainfall of 38 inches, while at Welling- 

 ton it is 23*8 inches and at Dubbo 22*8 inches, according to the 

 records at the Sydney Observatory. 



The general direction of Gilgandra from Orange is a little west 

 of north, the distance being approximately 120 miles, and the 

 whole of the area described is within that valuable wheat-growing 

 belt of country which runs throughout New South Wales, west
