The Origin of Chrysantliciniiiu Scgctuui Floiuin. 179 



ino- 21 rays in the terminal inflorescence, and as thus 

 coni])lying with the main condition for the new race. By 

 means of the grouping of the figures for the offspring, 

 that of one seed-parent (1895, No. 1 of page 175) was 

 first proved to be far better than that of the five other 

 parents. Then amongst this chosen group the inchviduals 

 with tlie largest number of florets in their terminal heads 

 were selected and amongst the best of these was found 

 the one which gave the faint indication already described.

 ANCESTORS OF THE DOUBLE RACE. 



But small though this indication was, it sufficed to 

 bring the latent character to light. All that was still ne- 

 cessary was to carry the process of selection on through 

 three years in the same direction and on similar prin- 

 ciples. 



I chose only one seed-parent each year for the 

 continuation of the experiment, isolated it together with 

 some of the next best as early as possible, and harvested 

 its seeds separately from those of its neighbors. Com- 

 pletely isolated plants of Clirysanflicinimi scgctiiin usually 

 set so little seed that it is impossible to rely on them, and 

 therefore fertilization has to be effected to a certain ex- 

 tent by inferior individuals. If this were not the case 

 my object would most certainly have been reached earlier.
