Trivia and notes: This beauty of this tree lies in its stately and graceful growth habit, somewhat like weeping willow. Honeybees congregate in great numbers while the tree is in flower. This tree must be long living (even in city pollution) as the tress described in Benthall (1946) are still there near the main entrance of Alipur zoo, hence must be well over 100 years old!

Where to Find: Very rare in Kolkata, Rabindra sarobar has only one, a mature tree in the south-western section of the lake (BRC side entrance). It is around 150 steps away from the main gate and is on the left-hand side near the main tar road (22.50939N,88.35673E)
