1923] WILSON, NORTHERN TREES IN SOUTHERN LANDS 87 



Don and P. nigra var. Poiretiana Schneid. which in New Zealand thrive 

 equally well on the poor volcanic soils of Rotorua and the rich alluvial 

 soils of the Canterbury Plain. There are, of course, minimum and maxi- 

 mum temperatures below and above which no species of tree will flourish 

 but with few exceptions excess of heat is better withstood than that of 

 cold. 



From the point of view of timber the Long-leaf or Southern Pine (P. 

 palustris Mill.) is the finest species of Pinus in the world. In the coastal 

 regions of Natal and those of New South Wales and Queensland where a 

 summer rainfall prevails this species, together with P. taeda L., P. caribaea 

 Morelet, P. glabra Walt., P. occidentalis Swartz and P. echinata Mill., ought 

 to be given a thorough trial.

 forest planting in Australasia and South Africa are:
