very much less influence on the properties of the hybrids 



the pollen parent; in Sets 9 and 3, a~ the pollen 



parent, it is less effective than the seed parent; and in 



bout equally effective as the seed parent. 



N. poeticus poetarum appears in Sets 1, 5, and G as the 



pollen parent. In Set 1 it greatly dominates the seed 



r in its influence; in Set 5 it is of somewhat less 



potency than the other parent; and in Set 6 it is almost 



completely dominated by the seed parent. N. ahscissus 



is the seed and the pollen parent, respectively, in Sets 7 

 and 8. In the former, it somewhat dominates the pollen 

 parent, and in the latter it is distinctly subordinate to the 

 seed parent. N. triandrus alius is the pollen parent in 

 Sets 11 and 12, in the former it being almost wholly sub- 

 ordinate, and in the latter of about equal value to the 

 other parent, in influencing the properties of the off- 

 spring. -Y. madams de graaff is of especial interest 

 because of its beiny a hybrid in Set 8, and the seed
