About
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 the common names native kumquat and desert lemon.
Uses
The desert lime fruit is a highly prized bushfood. Traditionally, it is wild-harvested from surviving bushland areas, where it is relatively common. However, C. glauca has also been extensively cleared from some areas due to the ongoing conversion of the wild bush into agricultural fields. The fruit are used in a range of products, including marmalades, beverages, and succade. It has a strong lime-like flavour.
