Didiplis diandra or lidwigia arcuata?

[Atxpunx]

Are there any features to separate the two? I believe I have one of these, I thought it was arcuata but now I'm having second thoughts. I'd be glad to post a pic but my lights are off for the night. I can post a picture tomorrow if needed. Thanks for any help!

They are similar so a picture is probably needed.

Ludwigia Brevipes is a 3rd species that can be mistaken for the two mentioned.

I recall because I was trading a bunch of plants for hardware and it was an acceptable substitution.

I broke down and bought a tissue culture pack of ludwigia arcuata. I will post a picture tomorrow o the plant in question, seeing as I've been at work all day again missed viewing my tank all together.
:sigh:

Now my Diandra looked more like your picture of the Ludwigia. The leaves on the Diandra were shorter slightly thicker. I finally removed it from the 220 as it was turning into a weed that wanted to overtake any plants around it.

This is what I got

That looks like Ludwigia to me. I looked through my pic's and unfortunately didn't have a picture of mine but the picture in this link is exactly how mine looked. It had a very distinctive look to it which reminded me for some reason of stars... MAC Forum 2.0 • View topic - Growing Didiplis diandra. It was a very tight growing plant that formed actual thickets.
