Thank you Sir for the plant & butterfly ID.

Your Polygonum glabrum inflorescence pictures are superb.

Attaching here a small sized pic of another aquatic plant that i thought was the same as this one (with the monkey-puzzle-butterfly). but this attached pic doesn't tally with yours shots.

Yes Sir, it is another species, your document (https://docs.google.com/document/d/1tOb9St_zAQymFT3J2B1yOuKuE9cxa9U9reVfpK-Yurw/edit) tells me so. But, as i said earlier, i thought both were same. However, i will post a seperate document seeking ID of this one too.
