racemes, appearing after the leaves. Fruit small, round, pui-p- 

 lish-black, or red, sweet and edible, but somewhat astringent. 

 An erect, slender shrub, three to twelve feet high. San Diego 

 northward to the Columbia River, and eastward to the 

 Rocky Mountains. I found this species with several natural 

 varieties growing in the canyons of New Mexico, at an eleva- 

 tion of seven or eight thousand feet. The fniit on some plants 

 are quite small and black, on others near by large or nearly 

 a half inch in diameter, and of a bright red color, and jjroduced 

 in long, droopmg racemes. I have some very promising seed- 

 lings of the large red variety, which I hope to fi-uit soon.
