Plant ID

Hi there

I am quit new to the planted tank scene and would really appreciate some help identifying the following plants in my tank:

 

My guess would be that both your first 2 plants are variations of Ludwigias and the 3rd is definitely water sprite...... The last one could well be some sort of dwarf lilly in the "Tiger Lotus" family.....

 

Second pic : Bacopa monnieri

 

and one more:

 

My guess would be ammannia gracilis.

 

Willow leaf hygrophilia

 

In your first post the first pick it looks more like Hygrophila difformis. Watersprite has got more of a rosette style growth and doesn't form such prominent nodes.
