There are two different plants here.

One with sinuate margins may be Potamogeton crispus L. 

Other may be some Aponogeton species as per comparative images herein.

Please look into this. 

I must say that is only one plant. Part which was above water had such strange leafs.

As I have collected and kept it in a freshwater tank, today I find that roots are emerging from that part.

I also attached a image which I captured just after uprooting the plant from its habitat.

I do not recall if I ever came across either of the two genera.

However, since the upper leaves are floating, as per "Bengal Plants", it would be Potamotgeton indicus Roxb = P. nodosus Poir. - https://www.gbif.org/occurrence/gallery?taxon_key=5301233

Please, note Potamogeton has creeping rootstock, while Aponogeton features tuberous rootstock.

Thank you.

Best regards,
