il Natural Hybrid 



This natural hybrid raspberry was found growing wild 

 by Mr. Burbank in Alberta, Canada. It was brought to Santa 

 Rosa, and has been used in various hybridizing experiments. The 

 chief interest of the plant, however, is that it is a natural 

 hybrid that was growing in a state of nature, and appar- 

 ently competing successfully with both of its parents.
