OTHER RASPBERRIES 297 



berries of the Old World from a single species, still 

 greater results may be expected from the ameliora- 

 tion of two species which freely hybridize. 



Outlying Types 



The Salmon -berry of the Pacific coast has come 

 into cultivation within the last very few years as a 

 fruit plant. The best type is Rubus Nutkanus var. 

 vclutinus. Charles Howard Shinn, of the California 

 Experiment Station, writing in "Garden and Forest" 

 in 1894, says that this plant "belongs more distinctly 

 to the northern California coast, where it is highly 

 esteemed, but it does not grow well elsewhere." 

 Wickson, in "California Fruits," says that the variety 

 "thrives best in the upper coast counties, and 

 efforts to introduce it as a commercial fruit generally 

 throughout the state have not proved successful." 

 Ruins Nutkanus itself ranges from northern Michigan 

 to Alaska and New Mexico, always being a boreal, 

 subalpine or highland plant. It is closely allied to 

 the common flowering -raspberry, or Rubus odoratus, of 

 the East, from which it differs chiefly in having 

 white flowers, a less dense clothing of glandular 

 hairs, less acuminate lobes to the large leaves, and a 

 larger fruit. It bears a large and sweet hemispherical 

 red fruit. This species itself, as well as the variety 

 velutinus, is recommended for cultivation. Both are 

 known as Salmon -berries.
