Dioscorea transversa, Pencil yam, is a vine of eastern and northern Australia.[1][2]

The leaves are heart-shaped, shiny, with 5-7 prominent veins. The seed pods are rounded, green or pink before drying to a straw brown papery texture. The edible tubers are typically slender and long. There are two forms: an eastern rainforest and wet sclerophyll form which doesn't have bulbils, and a northern form which occurs in open forests and has small bulbils and large inground tubers.[3]

Uses[edit]

The tubers are a staple food of Aborigines and are eaten after cooking, usually in ground ovens.[3]
