Aulax is a genus of shrubs in the family Restionaceae, commonly known as the Cape rushes. These plants are native to South Africa and are characterized by their grass-like appearance, with slender, erect stems. Aulax species typically have a dioecious nature, meaning individual plants are either male or female, with distinct flower structures. The male plants produce showy, often colorful flower heads, while the female plants have less conspicuous flowers that develop into small, woody capsules containing seeds.

The genus Aulax comprises several species, each adapted to specific ecological niches within the Fynbos biome. These habitats are often characterized by sandy soils, dry summers, and winter rainfall. The plants play a role in soil stabilization and are part of the diverse flora found in these regions. Their tough, wiry stems make them resilient to fire, a common disturbance in their native environment. Reproduction in Aulax is primarily through seed dispersal, with some species also capable of vegetative spread.

Cultivation of Aulax is not widespread, but some species are grown in specialized gardens for their unique texture and form. They require well-drained soil and a climate that mimics their native South African conditions. Due to their specialized habitat requirements, they are generally considered difficult to grow outside of their native range. Conservation efforts may be necessary for some Aulax species due to habitat loss and other environmental pressures in their natural distribution.
