Seringia nephrosperma, commonly known as free-carpel fire-bush,[2] is a species of flowering plant in the mallow family and is endemic to northern Australia.

It is an upright, suckering shrub with hairy new growth, usually oblong to lance-shaped leaves, and purple flowers arranged in groups of 5 to 25.

The flowers are purple with petal-like sepals opening to 20–30 mm (0.79–1.18 in) wide, covered on the back with white, star-shaped hairs.

[2][3][4] This species was first described in 1863 by Ferdinand von Mueller who gave it the name Keraudrenia nephrosperma in Hooker's Journal of Botany and Kew Garden Miscellany.

[6] The specific epithet (nephrosperma) means "kidney-shaped", referring to the shape of the seeds.
