THE PRIMUS BERRY 



This highly interesting plant is one 

 of the first that could properly be 

 termed a new species developed under 

 the direct guidance of the hand of the 

 experimenter. It is the progeny of the 

 California dewberry and a hardy little 

 berry indigenous to Siberia and Rus- 

 sia, called the Siberian raspberry. The 

 remarkable Primus berry appeared as 

 a first generation hybrid, and it always 

 breeds true, having the characteristics 

 of a new and permanent species.
