Citrus glauca, commonly known as the desert lime, is a thorny shrub or small tree native to Queensland, New South Wales, and South Australia. The 1889 book The Useful Native Plants of Australia records common names native kumquat and desert lemon.

Bush tucker, also called bush food, is any food native to Australia and historically eaten by Indigenous Australians, the Aboriginal and Torres Strait Islander peoples, but it can also describe any native flora, fauna, or funga used for culinary or medicinal purposes, regardless of the continent or culture. Animal native foods include kangaroo, emu, witchetty grubs and crocodile, and plant foods include fruits such as quandong, kutjera, spices such as lemon myrtle and vegetables such as warrigal greens and various native yams.
