41197 to 41243. Solanum tuberosum L. Solanacea\ Potato. 



" Peru is the home of the potato, which is the principal crop throughout 

 the region of the high table-lands and along the eastern and western 

 slopes of the Cordilleras. On the western slopes, which arc exposed to the 

 cold, the cultivation of potatoes is carried down to the shores of the 

 Pacific, but on the eastern slope seldom extends below 8,000 feet, corn 

 becoming the dominant crop below 10.000 feet. The number of potato 

 varieties is very large, and a very great diversity of forms is shown, far 

 beyond anything with which we arc familiar in the United States. Un- 

 like the varieties of corn, most of which are named only by color, the 

 potato varieties have special names, though strains of different colors 

 are recognized in many of the varieties. No attempt was made to secure 

 a complete collection of varieties, but a scries of photographs was made 

 in order to show the general range of forms, The specimens were 

 brought back with a view to supplementing the collection of South 

 American varieties made by Mr. W. F. Wight in 1913."
