Hibbertia subvaginata is a species of flowering plant in the family Dilleniaceae and is endemic to Western Australia.

Hibbertia subvaginata is an erect, occasionally a spreading or straggling shrub, that typically grows to a height of 0.15–1.2 m (5.9 in – 3 ft 11.2 in).

[2][3] This species was first described in 1845 by Ernst Gottlieb von Steudel who gave it the name Candollea subvaginata in Lehmann's Plantae Preissianae.

[3][4] In 1880, Ferdinand von Mueller changed the name to Hibbertia subvaginata in Fragmenta Phytographiae Australiae.

[5][6] The specific epithet (subvaginata) derives from the Latin, sub-, ("somewhat" or "not completely") and vaginata ("sheathed") to give a Botanical Latin compound adjective meaning "somewhat sheathed" referring to the leaves.
