''pseudorugosa''〔 |}} ''Metrosideros polymorpha'', the ''ōhia lehua'',〔; 〕 is a species of flowering evergreen tree in the myrtle family, Myrtaceae, that is endemic to the six largest islands of Hawaii. It is a highly variable tree, being tall in favorable situations, and a much smaller prostrate shrub when growing in boggy soils or directly on basalt. It produces a brilliant display of flowers, made up of a mass of stamens, which can range from fiery red to yellow. Many native Hawaiian traditions refer to the tree and the forests it forms as sacred to Pele, the volcano goddess, and to Laka, the goddess of hula. Ōhia trees grow easily on lava, and are usually the very first plants to grow on new lava flows. It is a common misconception that the word ''ōhia'' is used to refer to the tree and that the word ''lehua'' refers only to its flowers. ''The Hawaiian Dictionary'' (Pukui and Elbert 1986: 199) defines ''lehua'' with these words: "The flower of the ''ōhia'' tree... ''also the tree itself'' (added )." Thus the ''Metrosideros polymorpha'' may be referred to correctly as a ''lehua'' tree, or as an ''ōhia lehua'', or simply an ''ōhia''.〔Wagner, W.L., D.R. Herbst and S.H. Sohmer. 1999.

University of Hawaii Press, Honolulu.〕 ==Distribution== ''Metrosideros polymorpha'' is the most common native tree in the Hawaiian Islands, tolerating a wide range of soil conditions, temperature, and rainfall. It grows from sea level right up to the tree line at elevations of and is commonly found in moist and dry forests, high shrublands, and is a colonizer of recent lava flows. It is relatively slow growing. Dominant in cloud forests above , the tree is also common in seasonally wet forests, where it may be dominant or form mixtures with the native ''Acacia koa''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「metrosideros polymorpha」の詳細全文を読む スポンサード リンク
