The Great Banyan is a banyan tree (Ficus benghalensis) located in Acharya Jagadish Chandra Bose Indian Botanic Garden, Howrah, near Kolkata, India. It was the widest tree in the world[citation needed] in terms of the area of the canopy and is estimated to be about 200 to 250 years old.[1] It became diseased after it was struck by lightning, so in 1925 the middle of the tree was excised to keep the remainder healthy; this has left it as a clonal colony, rather than a single tree. A 330 metre long road was built around its circumference, but the tree continues to spread beyond it.
