Wilson” with the pink N. castaliiflora brought both the nor- 
mal leaf development and the viviparous type, the flowers 
retaining the bluish color of the seed parent. The seedlings 
showing the vegetative leaf character have an extremely low 
percentage of fertile seeds, whereas the non-vegetative types 
have a high percentage of minute seeds for perpetuating the 
type. The influence of the parent, NV. castaliiflora, is appar- 
ent in the enlargement of the sepals and petals and the 
Nymphaea “Mrs. Woodrow Wilson” var. gigantea: 
1, sepal; 2, petals; 3, stamens; 4, submerged leaves 
of seedling; 5, first floating leaf. One-half natural 
size.

petals. However, there is no increase in the number of 
petals above that of the seed parent. The purple markings 
are more numerous than in NV. “Mrs. Woodrow Wilson” ; 
they are totally absent in the sepals and petals of N. 
castaliiflora. 
The variety so strongly suggests the seed parent that a 
varietal name indicating a major form has been attached. 
It may be distinguished from the type, however, by the tall 
peduncles terminating in a much larger flower, darker blue 
color, pink in the interior of the sepals and petals, the in- 
tensified markings externally, the larger leaves overlap-
