DELIGHTFUL BERRIES 319 



conspicuous degree when crossed with some of 

 our northern species. 



Among other good qualities of the hybrid 

 progeny, there should be a tendency to prolonged 

 bearing, such as we have seen in the case of the 

 strawberry produced by the crossing of species 

 from the two hemispheres. 



THE SALMONBERRY 



Another very interesting Rubus that shows 

 great possibility of development is the native 

 species familiar along the Pacific Coast from cen- 

 tral California to Alaska known as the Salmon- 

 berry, Rubus spectabilis. 



This is a tall, erect bush or small tree with 

 stout, perennial canes. The stalks are usually 

 sparsely clothed with weak, slender prickles, but 

 are sometimes nearly smooth. The flowers are 

 borne singly and in pairs on slender stalks ; they 

 are large and showy, being bright red or purple. 



In Humboldt and Mendocino Counties, Cali- 

 fornia, I have seen this berry growing in the 

 pastures where it became a genuine tree from 

 twelve to fifteen feet in height, some of the stalks 

 being two or three inches thick. It is reported 

 sometimes to grow six inches in diameter. The 

 cattle in the pastures browse on the plants as high 

 as they can reach, and the berries are gathered
