   This member of the Dioscoreaceae family was given this name by Carl Linnaeus in 1753. It is found in tropical Asia and Africa (and now in southern USA and northern South Africa), growing in a rich and well drained soil with some water and little to some sun. The caudex can grow to 18 centimetres in diameter, the vines can reach for six metres. The rarely seen flowers are tiny and white.
