This member of the Dioscoreaceae family was given this name by Nathaniel Wallich in 1842. It is found in forests of Assam, Bangladesh, south-central China, Himalaya, India, Myanmar, Nepal, Thailand, Tibet, Vietnam and perhaps Afghanistan and Pakistan? It is growing in a rich soil with some water and little to some sun. The caudex can grow to 20 centimetres in diameter, the entire plant to three meters in height. The flowers are cream-white. This is yet another dioecious Dioscoreaceae: Either male or female plant.

Dioscorea is named after Pedianos Dioscorides, a Greek physician if the 1st century A.D. The species name means 'triangular'  for the petals. Like Greek letter Δ - delta.
