THE MUTANT "POINSETTIA" 



This mutant is one of the most distinct in habit of all the mutants so far discovered. Its 

 long, narrow, dark-green leaves are clustered at the ends of the branches in a fashion sug- 

 gestive of the plant from which it has been named. (Fig. 14.) 



"NEW SPECIES" OR ' N. S." MUTANT 



This plant proved sterile in several attempted crosses. Tests have shown that this mutant 

 differs from all others investigated in that it breeds true as a distinct new race. Here we 

 appear to be witnessing the birth of a new species. (Fig. 15.)
