is due to imperfect development caused by insufficient or impotent 

 pollen."* 



In our work with tomatoes and egg plants there has in no case 

 occurred an instance of immediate effect, other than alteration of 

 form due to insufficient pollen. During the past winter numerous 

 crosses and hybridizations of tomatoes have been made. The 

 accompanying photographs of the most violent of these crosses 

 indicate the entire absence of apparent effects. 



Fio-ure 1 represents the "Lorillard," crossed by pollen of the 

 "Currant," {Ly coper sicum escnlentum crossed by L. PimpinelU- 

 folium). The Lorillard is a smooth, nearly spherical variety, of 

 medium size, and as grown under glass, seldom weighs more than 

 three or four ounces.

As will be seen, the fruit is in every respect typical of the 

 Lorillard. The offspring from this cross, however, show unmis- 

 takable evidences of the influence of the male parent, both in the 

 habit of the plants and in the character of the foliage and flowers. 

 The fruit also is intermediate between the parents in size and 

 character.
