This study on the leguminous plant Sesbania tchadica has made it possible to highlight its description, specification and identification in N'Djamena region S. tchadica (Sesbania Sesban Merr. (L)) is an annual tree that measures more than 4 meters in height. This species is abundant especially in Ndjamena. In most of the district of Ndjamena, S. tchadica was the most common type. S. tchadica shows a rapid early growth and grows well in various soils especially sandy siltstone and silty shale. The local inhabitants use the species in many ways: as a medicine, a livestock feed, for improving soil fertility, for fuelwood and to repel desert encroachment. In this study, various academic publishing websites like Science Direct, Springer Nature, some online international plant databases, and other national data herbaria from the republic of Chad were used to identify, describe and summarize the research literature on Sesbania Sesban. This paper also describes the morphological characteristics observed in Sesbania Sesban from the republic of Chad and its taxonomy to assist in future program evaluations.
