It grows to between 1 and 2 m (3 ft 3 in and 6 ft 7 in) tall and has yellow flowers which appear from January to March or from June to November in the species' native range.

[2] The species was first formally described in 1806 by French naturalist Jacques Labillardière who gave it the name Candollea cuneiformis in his Novae Hollandiae Plantarum Specimen.

[3][4] In 1811, English botanist James Edward Smith changed the name to Hibbertia cuneiformis in Abraham Rees's Cyclopædia.

[7] Hibbertia cuneiformis grows on sand dunes and in swampy places in near coastal-areas of the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions of south-western Western Australia.

It is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
