The Fabaceae family in Bangladesh: Floristic analysis, species diversity, and new additions to the flora
Abstract
This study presents a comprehensive floristic analysis of the Fabaceae family in Bangladesh, highlighting its taxonomy, ecological significance, and conservation implications. Based on extensive reviews of published literature and herbarium records, 606 species across 147 genera were documented. Significant findings include the identification of Crotalaria (40 species), Dalbergia (34 species), and Indigofera (25 species) as the most species-rich genera, with a high Simpson’s Diversity Index of 0.98, reflecting substantial biodiversity and evenness. Life form analysis revealed dominance by trees (26.45%) and climbers (26.15%), with native species comprising 79% of the documented flora. The geographical distribution revealed the highest species concentration in the Chittagong division (31.64%), followed by Sylhet and Dhaka regions. This study also highlights 198 newly recorded species, emphasizing their importance for conservation and sustainable utilization. These findings contribute to understanding the ecological role of Fabaceae in supporting soil health, biodiversity, and agriculture in Bangladesh, offering a foundation for further research and conservation efforts.
