the work done with certain other daisy-like plants 

 — to which also reference was made in an earlier 

 volume — with particular reference to the interpre- 

 tation of the results accomplished, in the light of 

 the new information supplied us by observation 

 of other series of experiments. 



First a few words as to the progress of the 

 Shasta daisy, which, as we have learned, not only 

 constitutes virtually a new species, but has given 

 rise to a great variety of modified forms, all of 

 them Shasta daisies, yet differing as markedly 

 among themselves (in form at least) as, for exam- 

 ple, different races of roses or poppies or dahlias 

 differ. 



The racial strains of the three original parent 

 species have been so recompounded, and, as re- 

 gards their broader outlines, so truly fixed in the 

 new species, that no one who sees a Shasta daisy 

 can fail to recognize it as a Shasta — ^just as we 

 recognize a rose or a poppy or a dahlia — even 

 though the particular specimen under observation 

 differs very radically as to size and form and ar- 

 rangement of petals from anyone of the half dozen 

 varieties that may be under observation at the 

 same time. 



And the meaning of all this has been made 

 clear to us in our studies of other forms. The 

 separation of unit characters through hybridizing
