Bossiaea aquifolium, commonly known as water bush, nedik[3] or netic, is a species of flowering plant in the pea family Fabaceae and is endemic to Southwest Australia.

Bossiaea aquifolium is a slender shrub or tree that typically grows to a height of up to 8 m (26 ft) and has thin, sometimes hairy branchlets.

[3][4][5][6] Bossiaea aquifolium was first described in 1864 by the botanist George Bentham in Flora Australiensis from specimens collected by James Drummond.

[10] The common name "water bush" is apt because rainwater collects in leaf axils, and splashes when the plant is brushed against.
