210 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. 



rain-forest areas of the State appear to have an average 

 annual rainfall approximating or exceeding 60 inches. The 

 areas in which this condition of rainfall prevails generally, 

 if not always, contain relatively large areas of rain forest of 

 the luxuriant type. A meteorological map showing the 

 distribution of rainfall in Queensland indicates roughly the 

 following areas with rainfalls approximating or exceeding 

 60 inches annually : — 



(1) The extreme south-eastern portion of the State, 

 including the MacPherson Range and Tam- 

 bourine Mountain ; 



(2) The North Coast line district, between Lands- 

 borough and Cooran; 



( 3 ) The small area round Yeppoon ; 



(4) The area between Mackay and Proserpine; 



(5) The fairly large area to the north, south, and 

 west of Cairns; and 



(6) The northern part of Cape York Peninsula. 



All of these areas, with the possible exception of Cape 

 York Peninsula, whose flora is not very Avell known, contain 

 tracts of heavy rain forest. Following are the average 

 annual rainfall registrations, in inches, of meteorological 

 stations situated in or near the rain forests of the areas 

 enumerated : — 



(1) Tweed Heads 70, Tambourine Mountain 64; 



(2) Landsborough 67, Montville 70, Nambour 60, 

 CjDoran 56, Kin Kin 57 ; 



(3) Yeppoon 65; 



(4) Eungella 72 for 1913, Mackay 69 ; and 



(5) Cainis 90, Atherton 53, Harvey's Creek 165. 



It is evident that the luxuriant rain forests are indica- 

 tive of a heavy rainfall. 



On the other hand, certain types of vegetation — for 

 example, brigalow (Acacia harpophylla) "scrub" — indicate 

 a relatively low rainfall. Extensive areas of brigalow forest 

 occur between Dalby and Roma on the Western, between 

 Warwick and Goondiwindi on the South- Western line (C. T. 

 AVhite), and between Westwood and Emerald on the Central 

 line. These three areas have an average annual rainfall of
