Darwinia diosmoides is a shrub which is endemic to the south-west of Western Australia. It usually grows to between 0.3 and 1.2 metres in height and produces white flowers. The species was formally described in 1828 by Swiss botanist Augustin Pyramus de Candolle who gave it the name Genetyllis diosmoides. It was transferred to the genus Darwinia in 1865 by English botanist George Bentham.
