40. Yam Bean 

 Pachyrhizus erosus 



The roots of this plant are always eaten raw but the young 

 pods may be cooked and eaten like string beans. This vege- 

 table is cultivated commonly in many parts of Central America, 

 especially from Costa Rica to Salvador, and in Mexico and some 

 parts of the West Indies. The soft-stemmed vine has white 

 or purple flowers similar to those of beans. The small or large 

 tuberous roots resemble turnips. They are rather watery, sweet, 

 and refreshing in taste, and are nutritious. The yam bean 

 plant may also be called jicama.
