Metrosideros carminea (Carmine rātā, Crimson rātā or in Māori akakura) is a forest liane or vine that is endemic to New Zealand. It occurs in coastal and lowland forest. It is one of a number of New Zealand Metrosideros species which live out their lives as vines, unlike the northern rata (M.robusta), which generally begins as a hemi-epiphyte and grows into a huge tree.
Metrosideros perforata, also known as white rata, climbing rata, is one of twelve Metrosideros species endemic to New Zealand. It is one of three white flowering rātā vines (the others being large white rātā and white rātā).
