Daviesia divaricata, commonly known as marno,[2] is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia.

It is a low, spreading or erect and bushy shrub with phyllodes reduced to small, triangular scales, and orange and maroon flowers.

[2][3] Daviesia divaricata was first formally described in 1837 by botanist George Bentham in Stephan Endlicher's Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel.

[6] In 2017, Michael Crisp and Gregory T. Chandler described two subspecies in Phytotaxa, and the names are accepted by the Australian Plant Census: Marno grows on sand, over both limestone and laterite in near-coastal sandplains and dunes from near the Hutt River to near Busselton.

[2][3][8][10] Both subspecies of Daviesia divaricata are classified as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
