characterized by two rows of ray flowers instead 

 of one. Continuing the selection, flowers were 

 secured in successive generations having still 

 wider and longer rays and increased numbers of 

 rows, until finally handsome double-flowered va- 

 rieties were 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 differ- 

 ent types of flowers, it will be understood, have 

 the same remote ancestry, and represent the 

 bringing to the surface — the segregation and re- 

 combination and intensification — 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. 



I have never entertained a doubt 

 as to the transmissibility of ac- 

 quired characters and tendencies.
