Plants in the large, worldwide Mint Family (Lamiaceae) are generally fragrantly aromatic, annual and perennial herbs, subshrubs, shrubs, trees, and lianas with opposite or whorled, simple or deeply lobed leaves, square (4-angled) stems, tubular, usually bilateral flowers with 5 (sometimes 4) lobes and sepals, 4 (sometimes 2) stamens, and a superior ovary, and fruit in the form of four, 1-seeded nutlets. Many members of this family are cultivated as ornamentals, as herbs, or for their fragrant essential oils. Note: The former name for this family was Labiatae.
