No semblance of an ovary in connection with the pistilloid stamens was found in these -2-1A flowers, although this occurred in its de- scendants.

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