many flowers as the raspberry, seven or eight times; 

 as many as the strawberry. 



Tendencies strong in the parent, even though 

 for a time latent, usually come out strong in the 

 descendants. Ordinary hybrids of forms closely 

 related generally form a perfect blend from both 

 parents. When the parents are far apart all sorts 

 of variations occur, the so-called Mendelian con- 

 dition being one phase of the results. 



Hybridizing the iceberg white blackberry with 

 the Cuthbert raspberry develops a plant with fol- 

 iage and growth midway. About half the plants 

 bear fruit which is red like the raspberry, about 

 half bear fruit which is white like the iceberg 

 blackberry; the quality is midway between the 

 blackberry and the raspberry. In the crossed 

 fruit (first generation) the flavor is not superior,, 

 but it is quite intermediate between blackberry 

 and raspberry. The form of the receptacle is 

 intermediate. Some of the fruitlets separate at 

 the base, but not above. In crossing it makes no 

 difference which sex is taken as the male parent;
