}}
Eutrema is a genus of flowering plants of the family Brassicaceae, native to the Holarctic. Its best known member is wasabi, Eutrema japonicum. The name comes from the Greek εὐ- (eu-) 'well' et τρῆμα (trêma) 'hole', because of a hole in the septum of the fruit.{{cite web |url=http://beta.floranorthamerica.org/Eutrema |title=Eutrema R.
