Abstract
Fabaceae is the second largest flowering plant family (after the Asteraceae) with approximately 17,500 - 18,000 species belonging to 786 genera primarily distributed in tropical regions. In Vietnam, over 450 species from 90 genera have been reported, showcasing a rich diversity in habitat and distribution. Many species in this family are valuable for their timber such as Rosewood (Dalbergia cochinchinensis Pierre), and Sua wood (Dalbergia tonkinensis Prain); they also provide medicinal ingredients and food sources like Mung beans (Vigna radiata (L.) R.Wilczek) and Black gram (Vigna mungo (L.) Hepper). This research has been conducted to identify the morphological and anatomical characteristics of Sesbania sesban (L.) Merr., a species found in Tan Hung district, Long An province. Fresh samples of the species were collected and analyzed, describing the morphological features and anatomy of the reproductive and nutrient organs. The study revealed that the stems and leaves of S. sesban exhibit adaptations to strong light conditions, with stomata mainly concentrated on the lower leaf surface, stem hairs that aid in light reflection and moisture retention, and root nodules containing Rhizobium bacteria for nitrogen fixation. The anatomical structure of the nutrient organs showed strong development of pith and wood rings, indicating the adaptation of S. sesban to windy environments near river banks and canals.
