Tremulina tremula
Tremulina tremula is a plant in the Restionaceae family, found in the south-west of Western Australia.
It was first described in 1810 by Robert Brown as Restio tremulus, but was transferred to the genus Tremulina in 1998 by Barbara Briggs & Lawrie Johnson.
The species epithet, tremula, is a Latin adjective, which describes the plant as trembling or shaking.
