48 NOTES ON NATIVE FLORA OF NEW SOUTH WALES, VI., 



until near Deepwater it grows at an elevation of about 3,200 feet 

 above sea-level. The species is one which prefers river-flats to 

 hills, and from the localities it frequents on northern New 

 England, it can generally be traced along the valleys to the 

 lower country on the Western Slopes. Mr. Andrews has drawn 

 my attention to the fact that it is a lover of the blue granite. 



The occurrence of Casuarina Luehmanni at Deepwater is of 

 greater interest than that of Eucalyptus conica, as the former is 

 a more typical Interior tree, and continues southerly across the 

 north-western part of Victoria into South Australia. Specimens 

 of this Casuarina have also been collected 7 miles beyond Wall- 

 angarra in Queensland by Mr. E. C. Andrews, and it is common 

 on the watershed of the Upper Hunter and Goulburn Rivers, 

 having crossed the lower portion of the Liverpool Range from 

 the west. Its size around Deepwater quite equals that attained 

 in the western districts. 



It has been noticed that many plants which belong to the 

 Western Slopes and which are restricted to comparatively low 

 levels in the south, appear to ascend very considerably on western 

 New England. This great difference is probably to some extent 

 due to the very cold influence in the south, which radiates from 

 the snow-clad heights of Kosciusko, whose altitude exceeds 7,000 

 feet. If a similar mountain area of equal height existed in the 

 north of this State, it would be likely to prevent the ascent of 

 many western species to their present elevations. If, on the 

 other hand, the local conditions were the same throughout the 

 Mountain Area, the upper limit of the plants of the Western 

 Slope would rise with greater regularity along a more even grade. 

 It is probable the diminished effect in the north of the cool 

 southerly wind exercises some important influence in the matter,, 

 as although the elevation is greatest in the south, the land mass 

 which exceeds, say, 3,000 feet, is greater in extent in the north. 



Aroimd Stannum and Torrington. 



The country around Stannum and Torrington,, which ranges 

 from 3,400 to about 4,000 feet, consists chiefly of hills composed
