Description: Description of the mint family, with images of selected species.
Flowering Plant Families, UH Botany The Lamiaceae are mostly herbs or shrubs comprising about 200 genera and 3,200 species, commonly with aromatic, herbage, quadrangular stems, and verticillate inflorescences. The leaves are opposite or whorled, and are simple or occasionally pinnately compound; stipules are absent. The flowers are bisexual and zygomorphic. The calyx is synsepalous, typically 5-merous, sometimes 2-lipped, and usually has 5-15 conspicuous ribs. The corolla is sympetalous and typically bilabiate with 2 lobes forming an upper lip and 3 lobes forming a lower lip. The androecium consists of either 4 didynamous stamens or only two stamens that are adnate to the corolla tube or perigynous zone, alternate with the lobes. The gynoecium consists of a single compound ovary of 2 carpels, a single gynobasic style, and a deeply 4-lobed superior ovary with 4 apparent locules (by intrusion of the ovary wall), each with a single basal-axile ovule. A hypogynous, often asymmetric nectariferous disk is generally present between the stamens and ovary. The fruit consists of four 1-seeded nutlets that rarely may be fleshy and drupaceous.
