Morphological characteristics were observed using a magnifying glass and a microscope with staining techniques. DNA analysis was performed using the Sanger method, and the chemical composition was analyzed using the modified Ciuley method. The results showed that the water primrose plant harvested in Tra Vinh is scientifically named Ludwigia hyssopifolia G.Don Exell, belonging to the Onagraceae family. Its characteristic morphological features include a herbaceous stem, alternate single leaves, bisexual flowers, usually with 4 sepals, 4 petals, 8 stamens in 2 whorls, inferior ovary, and central stigma. Microscopic data from stems and leaves and chemical analysis revealed the existence of fatty acids, free triterpenoids, anthraquinones, and glycosides.
