De Nederlandse slijkgrassen

The common Rice grass in the Netherlands proved to be Spartina anglica C. E. Hubbard instead of S. x townsendii H. & J. Groves as has been cited in Dutch literature. In less than 55 years after its introduction in 1924 S. anglica succeeded in almost completely crowding out the original S. maritima (Curt.) Fern. According to C. E. Hubbard, who kindly revised several of our specimens, only 4 collections belong to the hybrid S. x townsendii, 2 to a triple-hybrid? S. anglica x (S. x townsendii) and one to an unknown Spartina-hybrid.
