The Lamiaceae, or mint family, contains about 200 genera and 3500 species of mostly herbs, some shrubs, and a few trees and climbers. It was known at one time as the Labiatae because the flowers typically have petals fused into an upper lip and a lower lip, but now takes its name from genus Lamium. This is a family that is familiar to most people due to its aromatic qualities and because it includes such important herbs as basil, mint, rosemary, sage, savory, marjoram, oregano, thyme, and lavender. It is a close relative of the vervain family and some phylletic revision is underway. The leaves are opposite and decussate or whorled, the stems are frequently square in cross section, and the flowers are bi-laterally symmetric with five united petals and five united sepals. Some other members familiar to most people are coleus, chia, and catnip. Aromatic oils are also utilized in the perfume industry.
