Many of the trees landmarked, and presented here as individuals, were actually combinations of multiple trees of different species.
When trees were planted together, and fused together over time into a mass of wood, they were labelled with this tag. Some trees have epiphytes growing on them- plants growing on their branches. If one of the epiphytes is identifiable as a small tree, then this combination of trees was marked as a fusion.
Often, a Ficus tree, such as peepal or banyan, began life as seedlings deposited high in the branches of a host tree. Over time, they send their roots towards the ground, and may eventually engulf and kill their host tree. Sometimes, however, they will grow together in relative harmony, and be encountered as a fused tree. These Ficus trees were also found growing in crevices and cracks on buildings throughout India.
