Examples of Australian native plant foods include the fruits quandong, kutjera, muntries, riberry, Davidson's plum, and finger lime. Native spices include lemon myrtle, mountain pepper, and the kakadu plum. Various native yams are valued as food, and a popular leafy vegetable is warrigal greens. Nuts include bunya nut, and, the most identifiable bush tucker plant harvested and sold in large-scale commercial quantities, is the macadamia nut. Knowledge of Aboriginal uses of fungi is meagre, but beefsteak fungus and native "bread" (a fungus also), were certainly eaten.
