Lamiaceae (Labiatae) — the mint family
Lamiaceae, or Labiatae, is the aromatic mint family of flowering plants. It includes many culinary herbs, ornamentals and medicinal species characterized by square stems and two-lipped flowers.
Lamiaceae, commonly called the mint family and historically known as Labiatae, is a widespread group of flowering plants. Estimates vary, but the family comprises roughly about 210 genera and around 3,500 species, with diversity concentrated in temperate and Mediterranean climates. Members range from low-growing herbs to shrubs and rarely small trees.

Distinctive characteristics
Lamiaceae are most often recognized by several recurring features: stems that are frequently square in cross-section, leaves set in opposite pairs, and flowers that are typically bilabiate (two-lipped). Many species bear glandular trichomes that produce volatile oils, giving the foliage a characteristic aroma. The fruit generally consists of four small nutlets. These morphological traits help distinguish members of this family in the field.
Taxonomy and evolutionary relationships
The family name Lamiaceae derives from the genus Lamium. Historically treated under the alternative name Labiatae, modern botanical nomenclature prefers Lamiaceae. Molecular phylogenetic work since the late 20th century reshaped understanding of related groups: many genera once placed in Verbenaceae have been reassigned to the Lamiaceae, while the core Verbenaceae were found to be more closely allied with other families within the order Lamiales. This rearrangement reflects DNA-based analysis rather than solely traditional morphological classification.
Uses and examples
Members of the mint family are prominent in human culture and economy. They supply widely used culinary herbs and spices, essential oils for perfumery and aromatherapy, and ornamental plants for gardens. Common and well-known genera include Mentha (mint), Ocimum (basil), Lavandula (lavender), Salvia (sage), Thymus (thyme) and Origanum (oregano). Their aromatic foliage and nectar-rich flowers also make them valuable for beekeeping and pollinator-friendly plantings.
Notable distinctions and facts
- Common field identifiers: square stems, opposite leaves, bilabiate corollas and four nutlets.
- Economic importance: culinary herbs, medicinal species, garden ornamentals and essential oils.
- Taxonomic caution: generic limits and species counts can vary as taxonomists revise classifications based on new molecular data.
For an overview of the group's diversity and classification consult botanical references or regional floras. The family remains one of the most familiar and useful plant groups worldwide, combining distinctive morphology with broad cultural significance.
