Island Morning Glory

Thanks, Ron. I've updated the title, scientific name and the wiki link.

This is Ipomoea indica and there is a calyx tip left center of the photo which are the sepals of Ipomoea indica.

Ipomoea nil is long growing climber plant and mostly seen for Ornamental wall decorations. Its now across the world.

Thanks, Ashish. I updated the scientific name and the wiki link.
