Notothyrus

Notothyrus is a genus of flowering plants in the family Fabaceae, commonly known as the pea family. The genus is native to Australia. Species within Notothyrus are typically small shrubs.

The genus Notothyrus contains only one recognized species, Notothyrus sympetalus. This species is characterized by its distinctive fused petals, which is a key feature that distinguishes it from other genera in the Fabaceae family. The flowers are generally small and may be inconspicuous.

Notothyrus sympetalus is found in arid and semi-arid regions of Western Australia. It typically grows in sandy soils and is adapted to dry conditions. The plant's habitat is often associated with mallee scrub and open woodlands.

The conservation status of Notothyrus sympetalus is considered to be of least concern by relevant authorities, indicating that it is not currently facing significant threats to its population. However, like many native Australian plant species, its populations can be affected by habitat degradation and changes in land use. Further research into the specific ecological requirements and potential threats to this genus may be beneficial for long-term conservation efforts.
