The occurrence of Teucrium chamaedrys subsp. chamaedrys in the Netherlands is discussed. Since 1905 this subspecies has been present in one locality in the dunes south-west of Haarlem. Probably it was imported there with pheasant fodder. The plants maintain themselves easily but seem to be unable to make ripe seeds. As this subspecies has not yet spread, it is not included in the flora of the Netherlands.
