Banyan
The banyan (Ficus benghalensis) is an evergreen fig tree in the Moraceae family, native to the Indian subcontinent and Andaman Islands, where it inhabits seasonally dry tropical biomes such as monsoon and rainforests.[1][2] Characterized by its fast growth and aerial prop roots that descend from branches to form secondary trunks, it develops expansive canopies capable of spanning several acres, with heights reaching up to 30 meters.[3] Adapted to humid environments with well-distributed rainfall, the species tolerates altitudes from sea level to 610 meters and temperatures above 23°C, while exhibiting drought resistance for 4–6 months.[2][4] The Great Banyan in Kolkata's Acharya Jagadish Chandra Bose Indian Botanic Garden exemplifies its scale, covering nearly 1.9 hectares with over 2,800 aerial roots after more than 250 years of growth.[5][6] Revered in Hinduism as a symbol of immortality and the abode of deities, the banyan is India's national tree, embodying longevity and unity in cultural traditions.[7][8] Though not threatened globally, its invasive potential in non-native regions like Hawaii underscores ecological management needs.[1][9]Taxonomy and Etymology
Botanical Classification
The banyan tree, Ficus benghalensis L., is classified in the kingdom Plantae, phylum Tracheophyta, class Magnoliopsida, order Rosales, family Moraceae, genus Ficus, and species F. benghalensis.[10][11] This positioning reflects its status as a dicotyledonous angiosperm within the rosid clade, characterized by features such as syconium inflorescences typical of the Moraceae.[12] Within the genus Ficus, which encompasses approximately 850 species of mostly tropical trees, shrubs, and hemi-epiphytes, F. benghalensis belongs to subgenus Urostigma and section Conosycea, groups defined by their hemiepiphytic habits and aerial root development.[13] The species was first formally described by Carl Linnaeus in 1753 in Species Plantarum, with no accepted synonyms in current taxonomy, though vernacular names like "Indian banyan" distinguish it from related species exhibiting similar prop-root architectures, such as F. microcarpa.[12][11]| Taxonomic Rank | Name |
