RANGE. 



It is found in South Australia, Victoria, and New South Wales, and although it is 

 usually looked upon as a denizen of moderately dry country, a number of its localities 

 have good rainfalls. 



" Probably the tree which most definitely marks the dividing line between the warmer and colder 

 country floras (of New South Wales) is the White Box, the upper margin of its habitat, when met with in a 

 descent from the mountains, being an undoubted sign of an approaching warmer temperature, and in a 

 given latitude the presence or absence of this tree on the western slopes at once supplies the observer with 

 an approximate idea of the elevation. In following this species northerly a splendid example is seen of the 

 warmer effects of northern latitudes, for while in the southern district now described, the White Box is 

 chiefly found below an elevation of 1,300 feet above seadevel, on the northern part of New England it is not 

 uncommon at altitudes exceeding 2,000 feet." (R. H. Cambage in Proc. Linn. Soc, N.S.W., xxix, 687, 

 1904.) See also xxxvi, 567. 



It seems to present a very useful climatic boundary to agriculturists, 

 pastoralists, and others, in that it demarcates the western plains from the tablelands 

 (of New South Wales).
