Boronia inflexa Duretto Cyanothamnus inflexus is a plant in the citrus family Rutaceae and is endemic to tablelands near the New South Wales - Queensland border in Australia.

It is an erect, woody shrub with pinnate leaves and up to seven white to pink four-petalled flowers in the leaf axils.

Boronia bipinnata is similar but has larger, bipinnate or tripinnate leaves and smaller sepals and petals.

[2][3][4] This species was first formally described in 2003 by Marco F. Duretto who gave it the name Boronia inflexa in the journal Muelleria from a specimen collected in Girraween National Park.

[5] In a 2013 paper in the journal Taxon, Marco Duretto and others changed the name to Cyanothamnus inflexus on the basis of cladistic analysis.
