by two rows of ray flowers instead of one. Con- 

 tinuing the selection, flowers were secured in 

 successive generations having still wider and 

 longer rays and increased numbers of rows, until 

 finally a handsome double-flowered variety was 

 produced. 



Aberrant forms were also produced showing 

 long tubular ray flowers and others having the 

 rays fimbriated or divided at the tip. 



And all these divergent and seemingly different 

 types of flowers, it will be understood, have the 

 same remote ancestry, and represent the bringing 

 to the surface — the segregation and re-combination 

 — of diverse sets of ancestral traits that had long 

 been submerged. 



It is certain that no plant precisely like the 

 Shasta Daisy or any one of its varieties ever 

 existed until developed here in my gardens at 

 Santa Rosa. But the hereditary potentialities of 

 every trait of the new flower were of course 

 present in one or another strain of that quadruple 

 parentage, else they could never have made 

 appearance in the ranks of the hybrid progeny.

 to the trans missibility of 

 inherited or acquired traits.
