Fitzwilliamia

Fitzwilliamia is a genus of flowering plants in the family Asteraceae. The genus was first described in 1897 by Ferdinand von Mueller. It is native to Australia, with all known species found in Western Australia.

The plants in Fitzwilliamia are herbaceous perennials. They typically grow to be about 30 to 60 centimeters in height. The leaves are pinnately divided and have a somewhat tomentose texture. The flower heads are solitary, terminal, and radiate. They are composed of numerous florets, which are usually white or pale yellow in color. The fruits are achenes, which are small and dry.

There are currently two recognized species within the Fitzwilliamia genus: Fitzwilliamia anethifolia and Fitzwilliamia troxi. Fitzwilliamia anethifolia is found in the southwestern regions of Western Australia, often in sandy soils. Fitzwilliamia troxii is also found in Western Australia, typically in more arid inland areas.

The genus is named in honor of William Charles Wentworth Fitzwilliam, a prominent landowner and politician in New South Wales during the 19th century. Further research into the ecology and distribution of Fitzwilliamia species is ongoing. Conservation status for these species varies, with some considered common and others potentially facing localized threats due to habitat changes.
