and there are indications that some among them 

 will almost certainly prove of value as fruiting 

 plants for general culture. 



All of them appear to be hardy enough to stand 

 the climate of the central United States. It is to 

 be expected that hybridizing experiments will 

 further improve the fruit. The material is now in 

 hand for such experiments. 

 SOME NEGLECTED RELATIVES OF THE RASPBERRY 



Not to leave the field entirely to exotics, we 

 must note that there are several members of the 

 great Rubus family, closely related to our culti- 

 vated raspberries and blackberries, that grow at 

 our very door, so to speak, yet which have been 

 hitherto neglected or given slight aid in the devel- 

 opment of the latent fruiting possibilities we may 

 confidently expect in most members of this family. 



Among these are plants of a group represented 

 in the eastern United States by the Flowering 

 Raspberry, Rubus odoratus; in the central region 

 by Rubus deliciosis of Colorado, and along the 

 Pacific Coast from Alaska to Southern California

The eastern species is a handsome plant with

 of the lower hills and valleys, sometimes climbing 

 high up the mountain slope, and in Southern
