The water primrose has garnered noteworthy consideration due to its detrimental impact on both the economy and environment. Ludwigia adscendens is one of two species which represent the genus Ludwigia among theEgyptian aquatic flora. Therefore, understanding Ludwigia adscendens at deferent levels was essential to develop reasonable strategies to manage or utilize it positively. Life systems of different organs was conducted to provide a clear picture of the internal structures involved in the plant's survival in sewage biological system. Aerenchyma tissue, distributed as the main tissue in most organs, allows the plant to float and maintain balance.  SEM investigation revealed dust grains with diverse composition, symmetrical radiographic pattern, large size (58.5µm in polar diameter and 43.5µm in equatorial diameter), and oblate shape. DNA barcoding was supported using the rbcL gene for identification, revealing significant diversity across various biological and botanical methods.
