Dioscorea pentaphylla is a species of flowering plant in the yam family known by the common name fiveleaf yam. It is native to southern and eastern Asia (China , India , Indochina, Indonesia, Philippines , etc.) as well as New Guinea and northern Australia . It is widely cultivated as a food crop and naturalized in Cuba and on several island chains in the Pacific (including Hawaii).[1][2][3][4][5][6][7][8][9][10]
Dioscorea pentaphylla is a prickly vine that twines counterclockwise around objects and other plants. It may reach 10 meters in length. The alternately arranged leaves are compound, divided into 3 to 5 leaflets each up to 10 centimeters long. The plant produces horseshoe-shaped bulbils about a centimeter long. New plants can sprout from the bulbils. Flowers are borne in spikes. The vine grows from a tuber. Specimens may weigh 3 pounds and may be located over a meter underground.[2]
The tubers of the vine can be cooked and eaten.[11]
