The Ullucu, Ullucus tuberosus Caldas, One of the Mountain Root 

 Crops of Peru and Bolivia. (See S. P. I. Nos. 41 177 to 41 184.) 



In Peru the ullucu, or papa lisa, ranks next in popularity to the potato, being used largely in making 

 soups. The tubers resemble the potato very closely, 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 varieties spotted white and pink or light yellow and pink. The flavor is 

 peculiar and may not be attractive to American palates, but as the tubers are produced in abun- 

 dance, the possibilities of utilization should be carefully studied. (Photographed by G. B. Gilbert
