Here's a breakdown:

* Peepal Leaf: The leaves of the peepal tree (Ficus religiosa) are distinctive with their heart-shaped base and long, pointed tip.

* Margin: The edge of the leaf.

* Entire: A term used in botany to describe a leaf margin that is smooth and unbroken.

Therefore, the peepal leaf's entire margin contributes to its characteristic, smooth, and flowing appearance.
