very much less influence on the properties of the hybrids 

 than the pollen parent; in Sets 2 and 3, as the pollen 

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

 Set 4 it is about equally effective as the seed parent. 

 N. poeticus poetarum appears in Sets 1, 5, and 6 as the 

 pollen parent. In Set 1 it greatly dominates the seed 

 parent 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. abscissus 



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 13, 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- 

 spriag. N, madame de graajf is of especial interest 

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