of acid granite, often known as tin-granite, from its association 

 with valuable tin deposits. Quartz is so abundant that the 

 disintegration of this coarse granite results in the production of 

 a soil as sandy as that derived from the weathering of the 

 Triassic sandstone near Sydney and on the Blue Mountains. 

 The effect of geological influence on the vegetation is very 

 apparent on this particular area, for many Sydney species are 

 thriving here, imparting to the locality much of the appearance 

 of a typical sandstone flora. Appended is a list of plants noticed 

 on this acid granite formation extending from Stannum to
