Melicope is a genus of about 230 species of shrubs and trees in the family Rutaceae, occurring from the Hawaiian Islands across the Pacific to tropical Asia, Australia and New Zealand. The temperate Asian genus Tetradium (which sometimes include the tropical Euodia) is closely related to Melicope and is sometimes merged into it.
