Mint Family. 

 Aromatic punctate herbs, or shrubs (a few tropical species trees), mostly with 

 4-sided stems and simple opposite leaves; stipules none. Flowers irregular, 

 perfect, variously clustered, the inflorescence typically cymose, usually bracteo- 

 late. Calyx inferior, persistent, regular or 2-lipped, 5-toothed or 5-lobed (rarely 

 4-toothed), mostly nerved. Corolla with a short or long tube, the limb 4-5- 

 lobed, mostly 2-lipped, regular in a few genera; upper lip 2-lobed, or sometimes 

 entire; lower lip mostly 3-lobed. Stamens borne on the corolla-tube, typically 

 4 and didynamous, sometimes 2 with or without staminodia, rarely equal; fila- 

 ments separate, mostly slender, alternate with the corolla-lobes; anthers 2-celled, 

 introrse, or confluently 1 -celled, or sometimes of a single sac. Disk usually 

 present, fleshy. Ovary 4-lobed, or 4-parted, superior, each lobe or division with 

 1 mostly anatropous ovule; style arising from the centre of the lobed or parted 

 ovary, 2-lobed at the summit. Fruit of 4 i-seeded nutlets. Seed erect (trans- 

 verse in Scutellaria^); endosperm scanty, or usually none; embryo mostly 

 straight; radicle short, inferior. 



About 160 genera and 3000 species, of wide distribution in temperate and tropical regions. The 

 family is also known as Lamiaceae. The foliage abounds in volatile oils.
