ON DAISIES 



So it will be only an experimenter with plenty 

 of time on his hands who could undertake to fix 

 the type of the Shasta daisy by this rapid method. 

 The experimenter who has numberless other 

 plants to consider at the same time would be 

 obliged to content himself with the older method, 

 selecting, generation after generation, the individ- 

 uals that came truest to type, and preserving their 

 seed only from which to grow seedlings for another 

 selection next season. But this method, while 

 lacking the precision of the other, has served 

 admirably well in a multitude of cases, some of 

 which we have seen illustrated in recent chapters. 



So the exijerimenter who wishes to fix a race 

 of Shasta daisies may with confidence go about 

 the work along precisely the same lines that were 

 used, for example, in the production of the wild 

 heuchera with crinkled leaves — the method, for 

 that matter, through which the races of Shastas 

 were themselves developed after hybridization 

 had supplied the material for selection. 

 Coi-ORED Daisies 



It will be recalled that final hybridization 

 through which the Shasta daisy was produced 

 was made chiefly with an eye to the removal of 

 the last tinge of duskiness and a greenish yellow 

 shade that is more or less present in all white 

 flowers, leaving a flower of snowy whiteness.
