LARGE-LEAVED ASTER 



A. prcnanthoides and of A. cordifolius, but both 

 of these have smaller and more thickly set rays, 

 making smaller stars. 



However, one cannot escape the conclusion 

 that all three hybridize more or less, so that de- 

 termination of species, after all, is pretty much 

 a matter of averages.
