Abstract: The present study has been undertaken in Govindgarh lake situated in Rewa district (M.P.), India. The focal objective of the study is to evaluate the quantitative characters of the aquatic macrophytes viz., frequency, density, dominance and importance value index (IVI). During the whole study period, a total of 28 macrophytic plant species belonging to 28 species station A, 22 species station B, 19 species station C and 15 species station D were found distributed in the Govindgarh lake. Dominating species with IVI value Lagenandra ovata (120.27), Saccharum bengalense (111.27), Lemna trisulca (92.83) at station A, Vallisneria spiralis (71.34), Monochoria vaginalis (60.98), Ceratophyllum demersum (56.78) at station B, Ranunculus aquatalis (53.85), Vallisneria spiralis (31.12), Nymphaea stellate (30.75) at station C and Hydrilla verticillate (139.27), Ceratophyllum demersum (64.11), Cryptocryne retrospiralis (44.74) at station D. The analysis of variance (ANOVA) for all the aquatic macrophytes reported from the lake indicates that there is no significant variation within the four study sites in terms of distribution. However, F-test result indicates significant variation in the quantitative characters between the different macrophytic plant species of the lake.
