Rikkia

Rikkia is a genus of plants in the family Rutaceae, commonly known as desert limes. These plants are native to Australia and are found in arid and semi-arid regions. Rikkia species are typically small, shrubby trees or large shrubs, often with a thorny appearance. They are well-adapted to dry conditions, with small, tough leaves that help to reduce water loss.

The flowers of Rikkia species are usually white or pale yellow and have a characteristic citrus fragrance. They produce small, round fruits, which are also citrus-like in appearance and taste. These fruits are typically acidic and tart, and are sometimes used for culinary purposes, such as making jams, preserves, or as a flavoring agent. Indigenous Australians have historically used various parts of the Rikkia plant for food and medicinal purposes.

Several species are recognized within the Rikkia genus, with some of the more well-known including Rikkia coriacea and Rikkia triphylla. These plants play a role in their native ecosystems, providing food and habitat for various wildlife. Due to their resilience in harsh environments, Rikkia species are sometimes cultivated as ornamental plants in xeriscaping or as hardy citrus varieties. Their drought tolerance makes them an interesting subject for horticultural research and conservation efforts in arid regions.
