The Sunberry has unexpectedly been found 

 adapted to cold northern climates. In the Alberta 

 country, in the latitude of northern Alaska, the 

 Sunberry is highly appreciated, especially as it is 

 about the only berry that can be raised where the 

 thermometer often goes to 40 or even to 60 de- 

 grees below zero. 



VARYING TRAITS OF HYBRIDS 



From the standpoint of the gardener, the Sun- 

 berry has importance as a notable addition to the 

 list of small fruits. 



From the standpoint of the plant developer it 

 may be said to have perhaps greater importance 

 as illustrating the possibilities of the development 

 of new species by hybridization species markedly 

 different from, and in many ways superior to, 

 those from which they spring. 



It is true that other experiments have been 

 detailed that illustrate the production of new 

 forms of plant life through hybridizing already 

 existing ones. A few paragraphs back several of 

 these were named the Primus berry, the Phenom- 

 enal berry, and the Plumcot. But in the case of 

 these fruits, it will be recalled, the parent forms 

 were one or both bearers of valuable fruits. The 

 hybrid plants improved upon their parents, but did 

 not show entire departure from the traditions of 

 the races from which they sprang.
