Banyans are fig trees, especially the Indian fig tree (Ficus benghalensis), of the mulberry family (Moraceae). They are native to the Indian Subcontinent and are regarded as the national tree of the Republic of India.
Banyans are hemiepiphyte. They usually grow on another plant particularly at the canopy when the bird dispersed the fig seed and germinate at the top of the tree. The seed germinating in a crack or crevice of the host tree it will send its roots down to the ground. Soon the roots grow into the soil and become thick resulting into additional trunk of the fig tree.
Banyans used to specifically refer to the species, Ficus benghalensis. Soon, the name has been generalized to include all figs that have a common life cycle.¹
