Hi, I need help on ID'ing this plant. If it matters, I live near Houston, Texas.

I am a photographer so I don't know much about plants. I tried finding a similar plant on Google images but had no luck. Thanks!

It looks like Pistia stratiotes, water lettuce, an invasive species.

I ran across those, but I noticed that the leaf structure is different. Are there a lot of variations of it?

There are some minor variations, yes. Being from a distance and a B&W photo makes it a little harder to know for sure, but I am including a link to pics of the aquatic plants found in Texas. Hope that helps.

You are correct, that does not look like water lettuce other than the over-all plant form. (by the way, I really like the play of sunlight in your second pic)

Unfortunately I do not know what your plant is, but I will keeping looking for an answer.

It does look similar to frogbit, except it's leaves aren't glossy and the 'veins' are a different pattern... frogbit also looks flatter.

It is a water-primrose, genus Ludwigia.

There are a lot of species out there. Compare with this picture of Ludwigia repens for a start.
