Lamiales
The lilac-pink flowers of the water mint attract butterflies and beetles.
Plants in the mint family (Lamiaceae) are primarily identified by several distinct vegetative and reproductive features:
- Stems: They are characterized by square stems.1
- Leaves: The plants typically feature opposite, simple leaves.21
- Flowers: They produce bilaterally symmetric, two-lipped, open-mouthed tubular flowers. These flowers generally possess two or four stamens.21
- Ovary and Fruit: The ovary is composed of two carpels, each divided by a secondary partition to create four chambers. A characteristic feature is that the style arises deeply from within a central depression of the ovary. Upon maturity, the fruit typically separates into four nutlets.2
- Aroma: Many members of the family are well-known for being aromatic.1
While these features are common to the mint family, it is important to note that the Lamiales order as a whole is quite diverse, containing 24 families with various technical and molecular characteristics.3
