Help With Plant Identification?

[KevJ87]

Hey guys so one of the plants in my 29 gallon is causing some confusion. I have had a few different identifications given to me and was hoping the pro's at fish forums could solve the mystery. 

 
I have been told it is even like a hybrid strain of wort etc etc..
 
Here is the picture, this is an old picture from when the plants were just being transferred I am using this one since it is much easier to see the plant here than in the actual environment it is in now ( planted heavily with driftwood ).
 
 
 

 
 
The Sword / Anubis in this picture obviously aren't the one, it is  the large one in the center backgruond, look closely at the leaf pattern etc it is really strange like a hybrid.

It looks like a hygrophillia species to me.

It does indeed look a lot like a hygrophila. They often have different emmersed growth to their submerged growth, so it would look different if it's come in new from a supplier that grew it emmersed.

Hmm.. so is there any real way of actually figuring it out exactly?

I googled hygrophillia  and I can't find any species that has vine line appearances like mine has. It is so strange this plant, it has zero backbone to survive anywhere but submersed though. It is a very soft green vine with those leaf growths on it but instead of each "vine" being its own like plant it does have a regular root system like that of a sword plant.

Hmm, looks more like a bacopa monnieri type plant to me.
 
Although if you're thinking hybrid of hygrophila and to me hygrophila polysperma type seems closest imo but hard to tell really.

 

[KevJ87]

Yeah the polysperma hybrid of the hygrophila looks similar but its still not that exact species as it seems. Anyone know of a good plant expert that might be able to help me? I want to find out more about the speicies so I can do some correct splitting of it.
The problem with bacopa monnieri is that it grows typically much straighter and a little different looking than this I am having such a hard time identifying it.
