Metrosideros macropus

Metrosideros macropus,commonly known as the lehua mamo or 'ohi'a, is a species of tree in the eucalyptus family, Myrtaceae. It is endemic to the island of Oahu in the Hawaiian Islands. It is closely related to the widespread and highly variable ōhia lehua, found throughout the islands. Lehua mamo, however, is only found in the Koolau mountains. It is distinguished from M. polymorpha by the elongate leaf petioles and the flowers are usually yellow. The latter character is also found in some varieties of M. polymorpha, which normally has red flowers, but occasionally the flowers of M. macropus are red as well.
