TAXONOMIC AND MORPHOLOGICAL ANALYSIS OF THE FAMILY PAPILIONACEAE IN GARBHANGA RESERVE FOREST OF ASSAM, INDIA

Abstract

Papilionaceae, the third largest family of species worldwide, comprises both annuals and perennials with a diverse range of growth habits. The present study aims to explore and conduct a comprehensive taxonomic and morphological analysis of Papilionaceae in Garbhanga Reserve Forest (GRF) of Assam, India. Field survey was carried out across various habitats in GRF and the collected specimens were processed for herbarium preparation and then identified. Detailed morphological examinations on leaf structure, floral morphology, and fruit characteristics were conducted. Taxonomic keys followed by a detailed description together with phenology, distribution, information on type specimens, voucher specimen examined and IUCN status of the taxa are given. The result highlights the documentation of a total of 21 taxa under 16 genera, where climbers are represented by seven species, herb and undershrub by six species, and shrub and tree by one species each. Significant morphological variations were observed in leaves, flowers and fruits characters, providing critical insights into species differentiation. These findings enhance the understanding of Papilionaceae diversity in GRF and emphasize the importance of morphological studies in taxonomy, serving as a valuable resource for future botanical research and conservation strategies.
