This study was conducted to revise the taxonomic identity and clarify specific relationships within genus Lemna in Egypt. The studied species included: L. aequinoctialis Welw., L. gibba L., L. minor L., and L. trisulca L. The latter one was recorded as a new record to the flora of Egypt. Based on morphological traits, the numerical analysis showed a considerable degree of similarity among the studied species. It divided the Lemna species into three clusters. Cluster one included L. gibba and L. minor. Clusters two and three included: L. aequinoctialis and L. trisulca, respectively. Based on the degree of similarity, L. gibba and L. minor have the highest degree of similarity value 0.500 (50%), while the lowest one 0.174 (17.4%) was recorded between L. gibba and L. trisulca. This work proved the morphological similarity and dissimilarity among the studied species and added a new record to flora of Egypt.
