Abstract

The water hyacinth has garnered significant attention due to its harm effect on economics and ecology. Thus, understanding Echhornia  crassipes at different levels is necessary to figure out the suitable methods either for withstanding or using this species positively. Eichhornia crassipes is a synonym of Pontederia crassipes, a fast-growing hydrophyte, native to South America, belonging to genus Pontederia and family Pontederiaceae, monocots. The anatomy of different organs was addressed to provide a clear image of the internal structure of the species under study. This could explain the survival of this plant in the sewage ecosystem. Aerinchyma tissue was found in all organs, and water was obviously stored in the root to balance plant floating. In addition, pollen grains' characterization was recognized on SEM stubs with their monads, heteropoler, radiosymetry and large size (P-56/E-45µm). Identification of Echhornia  crassipes was approved via PCR and partial gene sequencing of rbcL gene (Ribulose Bisphosphate Carboxylase), which coincides with the gen bank. The present study encompasses molecular identification, as well as an anatomical and paleontological illustration.
