|Gunniopsis intermedia flower|
The name of the genus honours the botanist and politician Ronald Campbell Gunn. The genus was first formally described by the botanist Ferdinand Pax in 1889 in Engler and Prantl's work Die Naturlichen Pflanzenfamilien. The name is derived from the Greek word opsis meaning resembling which alludes to the resemblance of the genus to the genus Gunnia.
The plants are widespread throughout the eremaean zones of Western Australia and South Australia with some species extending into the areas in the Northern Territory, Queensland and New South Wales. Found in arid areas the plants are often found in shrubland area with saline soils in and around salt lake systems. The shrub-like Gunniopsis quadrifida has the largest distribution of all the species.
