Any idea gang? The one directly centered. Seems to be very sensitive to light intensity.

I'm thinking it's probably Ludwigia inclinata but I don't want to commit to that without a clearer picture.

Could it be a Eichhornia species? The lower stems do turn brown black over time, but the leaves do stay nice and light green.

I think it looks like a Ludwigia too.

I have a good amount of Eichornia diversifolia and unless there's some other species with different characteristics this one looks nothing like that.

Here are a few more pictures. COmapring to Kasselman on page 285, it is sure similar to the Eichhornia species.

How many leaves per node? Eichhornia diversifolia has alternate leaves. Yours appears to have opposite or whorled ones (much better pictures but it's still tough to count that). I think your answer is probably on page 376...

Valid points. This is definitely not Eichhornia diversifolia.

Looks like Nesaea pedicellata that's not getting a whole lot of light. Among other things, note the whitish look on the bottom of the leaves. Compare to the photo in the PF. You just don't see that on Ludwigia.

Wow! The plant is in a 55 gallon tank with 260 watts of light!

Crowded maybe? Low on micros? It could be either of those things too. It will usually take on an orangish tone when subjected to lots of light, nutrients and space. It can be a pretty big plant!
