This plant is grown for the small potato-like tubers which remain crisp after boiling. Growth is erect. Four to ten leaves, each 2 to 4 feet long, and with blades up to 2 feet, rise from the crown. The tubers are produced entirely under ground. The crop is of local importance in Puerto Rico and other Caribbean areas.
