Research work has been carried out to assess the number of total medicinal species of Fabaceae and evaluate their status in the flora of Bangladesh. The family has revealed significant richness with 169 (i.e. 67%) medicinal species under 61 genera among 254 total species under 69 genera. A total of 62 medicinal species are assessed to be threatened under different categories set by International Union for Conservation of Nature and Natural Resources (IUCN) due to environmental degradation, over exploitation and depletion of ecosystem diversity. Among them, 33 endangered, 7 critically endangered, 6 vulnerable and 16 rare. Out of 169 medicinal species of the family Fabaceae, 25 genera are represented by single species in the flora of Bangladesh. Among these 25 genera, 7 i.e., 28% are threatened. The study is based on long-term field investigations, examination of herbarium specimens and survey of relevant floristic and medicinal literature.
