The Aboriginal art symbol for a bush yam shows a round cross-section of the tuber (the edible part) and its root system.
The yam is a principal source of food in the bush. The leaves, which taste like spinach, are used as an anti-inflammatory medication. They are rich in vitamin B, minerals, protein and antioxidants.
The yam is a plant that regenerates year after year and as such has become a symbol of well-being and abundance in Aboriginal ceremonies.
