has produced a definiteness of species previously unsuspected in this Genus. This 

 stability is illustrated in a most striking manner by the associations between the 

 Tasmanian species and those of the mainland. 



Such, then, are our views of the probable evolution of the Eucalypts, 

 founded, as they are, on the broad basis of the natural classification previously 

 enunciated. 



Necessarily, our conclusions cannot always be expected to coincide with 

 those who have classified on morphological grounds alone so wonderful a, Genus 

 as the Eucalypts trees that will in the future be more fully appreciated, and 

 more highly prized in Australia than they are at the present day.
