Scirpus x mariqueter Tang & F.T. Wang (CYPERACEAE) is a pioneer plant of the tidal zone of estuaries of East Asia. Amplified fragment length polymorphisms (AFLP) were used to infer the relationship between S.xmariqueter and its putative progenitors, Scirpus planiculmis F. Schmidt and Scirpus triqueter L. The genetic distance between S.xmariqueter and S. triqueter was much higher than that between S.xmariqueter and S. planiculmis, and samples of S.xmariqueter and those of S. planiculmis did not form a monophyletic group, while the S. triqueter group formed a distinct monophyletic group. However, we also detected an apparent clustering of individuals of S.xmariqueter and S. planiculmis separately. Our results disprove the hybrid origin of S.xmariqueter and rather suggest that it is more closely related to S. planiculmis.
