THE SUNBERRY 301 



the very limits of affinity within which cross- 

 breeding is possible. 



We have discussed a number of instances in 

 which similar crosses have been made between 

 species widely separated. Such, for example, was 

 the cross between the California dewberry and 

 the Siberian raspberry, which produced the 

 Primus berry; also that between the dewberry 

 and the Cuthbert raspberry, which produced the 

 Phenomenal berry; and that between the plum 

 and the apricot, which produced the Plumcot. 



In each of these cases, it will be recalled, the 

 hybrid showed intermediate characteristics be- 

 tween its parents, constituting virtually a new 

 species, and proving its individuality by breed- 

 ing true to type from the seed. 



It was rather to be expected, then, that the 

 hybrid Solarium would similarly prove its 

 individuality, and the expectation was fully 

 realized. 



As the plants came to maturity, one bloomed 

 but failed to produce fruit. The others, how- 

 ever, fruited quite abundantly, some of them 

 profusely. 



The fruit was intermediate in size between the 

 fruits of the parent plants. Its quality was en-
