Oioi or jointed wire rush is commonly found growing near the coast, either in salt marsh or damp sand dunes. Oioi means 'to shake gently', which is a reference to the swaying of the stems in the wind.

Oioi is often found growing with sea rush (Juncus kraussii var. australiensis). The easiest way to identify oioi is by the dark bands along the stem that give the stem a slight zigzag appearance. Sea rush is green whereas the colour of oioi varies from dull green to deep orange and even purplish.
