What Is This Plant

[Alex.binge]

Hi all I have got a picture off two floating plant balls and I am wondering if anyone can identify the plant in the closest ball.

Not the best picture to ID it as it's half not there, but it could be a pogostemon erectus.

riccia is in the ball closest  or did you mean hydrocotyle  or ranunculus inundatus which is a little under the ball?

The ball in the front I did believe t was riccia. Thanks for your help xxx
