Triunia is a genus of medium to tall shrubs or small trees found as understorey plants in rainforests of eastern Australia. Members of the plant family Proteaceae, they are notable for their poisonous fleshy fruits or drupes. Only one species, T. youngiana, is commonly seen in cultivation.
==Taxonomy== Lawrie Johnson and Barbara G. Briggs described the genus Triunia in their 1975 monograph "On the Proteaceae: the evolution and classification of a southern family". The group of species in this genus was previously recognised as a subgenus, Macadamiopsis, of Helicia by Hermann Sleumer in 1955. T. youngiana was made the type species. This plant had originally been described in 1864 as Helicia youngiana before being transferred to the genus Macadamia.
