but when grown for floral display it is rather disappointing on ac- 

 count of the small size of the flowers. The writer therefore exper- 

 imented with a view of obtaining a white lily comparable to the 



day horticultural forms. Stock of N. "Mrs. Edwards 

 Whitaker" was selected as a desirable parent because its flowers 

 frequently bleach to white with age and also because white forms 

 resembling N. ovalifolia appear in the second generation. 



During 1919 reciprocal crosses were made between A r . "Mrs. 

 Edwards Whitaker" and its parent N. ovalifolia. A number of 

 seedlings were raised during the winter and planted in the ponds 

 outside. Nymphaea "Mrs. Edwards Whitaker" $ X ovalifolia 

 <? resulted in forms of the Whitaker type, while the reciprocal 

 cross, N. ovalifolia 6 x "Whitaker" $ , showed ovalifolia or the 

 white form as a dominant factor. One pure albino form possess- 

 ing the large Whitaker-shaped flowers and leaf characters was se- 

 lected as the desired type. It was carefully self-pollinated during 

 the summer of 1920, the offspring producing albino flowers. In 

 1921 the finest flowers were again selected and self-pollinated, the 

 seedlings again producing pure white flowers but with an im- 

 provement both in number and size of petals. By careful selec- 

 tion and self-pollination during the past season all pink and blue 

 shades which dominated the parent flowers have been eliminated. 

 The new hybrid produces plenty of fertile seeds, a factor not evi- 

 dent in most present-day hybrids.
