Marsilea shows pronounced morphological plasticity within species and as such it is difficult to
distinguish species depending on traditional morphology only. In recent years modern techniques viz.
molecular markers and PCR analysis have been employed for this study. In the present study genomic
analysis through RAPD markers has been employed for the first time to study interpopulational
differences between the same plants growing in different habitats. The present work was taken with the
specific aim of identifying populations of Marsilea species of hadauti region and to find out whether the
population variations are only morphological or are they genetically distinct. The results so obtained
indicate sufficient level of genetic diversity.
