Eremophila is a genus of more than 260 species of plants in the figwort family, Scrophulariaceae all of which are endemic to mainland Australia.
 (One species, "Eremophila debilis" is thought to be a recent arrival in New Zealand).
 Eremophilas are widespread in the arid areas of Australia, especially Western Australia and range in size from low-growing shrubs to small trees.
 The petals are joined, at least at their bases, into a tube with the upper petals different in size and shape from the lower ones.
 Some species have common names including emu bush, poverty bush or fuchsia bush, reflecting the belief that emus eat the fruit, their arid environment or a superficial resemblance to the flowers of plants in the genus "Fuchsia".
Wittrockia is a genus of the botanical family Bromeliaceae, subfamily Bromelioideae.
