I contend, that the number of the fexual organs in flowers is' more 



liable to change by the influence of foil or cUmate, or by the pro- 

 o-refsof time, than their fituations or proportions, or forms, and might 

 t1i,erefore probably be more advantageoufly employed in diftinguifiiing 

 their clafiTes and orders from each other, as well as in rendering them 

 more natural combinations. 



This mutability or uncertainty of the number of the organs of re- 

 produalon belonging to individual flowers, would feem to arife from
