GERMANDER, the name given to plants of the genus Teucrium (family Labiatae), comprising some loo species dis tributed all over the world. Both common British species (T. Scorodonia) and the common North American forms (T. cana dense and T. occidentals) are frequently known as wood sage. The European species were formerly used medicinally; T. marum, the cat thyme of southern Europe, is still so used. The plants are small, with small flowers remarkable for the slight development of the upper lip. T. Chamaedrys is wall-germander.
