 41177 to 41184. Ulltjcus tuberosus Caldas. Basellacese. Ullucu. 



" The ullucu or papa lisa is a root crop raised generally in the highlands 

 of Peru and Bolivia, in the region where potatoes are grown. The tubers 

 have a remarkably close resemblance to potatoes, except that the skins 

 are smoother and the colors brighter, running from white through various 

 intermediate shades to deep yellows and reds. There are also spotted 

 varieties, white and pink or light yellow and pink. Judging from its 

 representative in the native markets, the papa lisa ranks next to the 

 potato in popular favor in Peru, being used largely in the making of 

 soups, which is the principal branch of the culinary art among the 

 Indians. The flavor of the papa lisa is peculiar and usually not attrac- 

 tive to the unaccustomed palate. But being one of the plants that ac- 

 company the potato in Peru, it may not be without interest to observe its 

 behavior in the United States. The tubers are produced in abundance, 

 and if the plant should be found to grow readily the possibilities of 

 utilization should be carefully studied. The plant is a relative of the 

 so-called Madeira vine, familiar in cultivation as an ornamental climber. 

 A wild ullucu, common in the region of Sicuani. is very similar to the 

 Madeira vine, but the plants of the cultivated varieties do not attain a 

 length of more than 2 or 3 feet. The general appearance and habit of 

 growth are also somewhat like those of the sweet potato."
