Metrosideros bartlettii
 Bartlett's rātā (Metrosideros bartlettii) or the Cape Reinga white rātā is one of twelve Metrosideros species endemic to New Zealand and is notable for its extreme rarity and its white flowers somewhat uncommon in that genus of red-flowered trees and plants. Its natural range is in the far north of the North Island at Te Paki in three patches of dense native forest near Spirits Bay (34° S) that escaped destruction by fire namely Radar Bush Kohuronaki Bush and Unuwhao Bush.
