Floristic Diversity of the Family Fabaceae (Leguminosae) in Community Forests of South Haryana, India

Fabaceae is third largest family of angiosperms and second important family from commercial and economic point of view. The purpose of the present study was to examine the floristic analysis and species diversity of the family Fabaceae in Community Forests of South Haryana, India in view of recent classification recognised by Legume Phylogeny Working Group. Though the community forests are fragmented but still act as local mini biodiversity host spots harbouring rich plant diversity.

Repeated floristic surveys were conducted in different seasons during the year 2023 and 2024. Detailed field notes were recorded and photographs were taken in the natural conditions.

The outcome of study revealed 61 species belonging to 34 genera, 16 tribes and 4 subfamilies from the studied area. The subfamily Papilionoideae is the most dominant, comprising 10 tribes, 21 genera and 41 species. Phaseoleae is the largest tribe with 7 genera and 9 species, followed by Mimoseae with 4 genera and 4 species. Indigofera emerged as the largest genus, comprising 8 species. The Simpson's index value proved that the Fabaceae family in Community Forests has high diversity. The analysis of growth form indicated that the Fabaceae family is dominated by Herbs with a proportion of 48%. Therophytes have highest number of species (44%), followed by Phenerophytes (36%), Chaemephytes (18%), Hemicrytophytes (2%). The findings of the present study will be helpful for botanists, conservationist, policy planners and local people for effective management of community forests.
