I have seen a Banyan tree in India located in the state of Andhra Pradesh.
The Forset Dept.of this state says that this is the Longest tree with 1650 roots and 570 years old.
Thimamma marammu fondly called is located in a village say 27Kms from Kadiri,Anantapur Dist of Andhra pradesh in India.
Bhadrinath.
