from the same cross were grown, but no other pistilloid mutant was 
found among them. The plant was designated (-2-1A) and in all 
subsequent experiments will be known under this number. Over no 
of its flowers were examined, all of which showed the character in each 
stamen, although there was considerable quantitative variability. 
No semblance of an ovary in connection with the pistilloid stamens 
was found in these -2-1 A flowers, although this occurred in its de- 
scendants. Cuttings of the mutant were made, and selfed seed procured 
from which 90 offspring were obtained, 72 of which reproduced the

character in all faithfulness, and were in all apparent respects like the 
parent. Eleven of the progeny developed flowers with only two or 
three or at most four pistilloid stamens, and in these, the anomalous 
pistils were much smaller than those of the original (-2-1 A) or of its 
72 offspring. Seven of these offspring entirely lacked pistilloid sta- 
mens. At first, such a state of affairs was very ptizzling, as the 
possibility of technical error was not taken into consideration. How- 
ever, there were sap-colored flowers among the progeny, which was
