Headwaters Spring Plant

I converted another tank to soil substrate and planted this at one end about a week ago... seems to be doing OK so far at one end of a 55 gallon tank... Ignore the brown dust on the lower leaves that is just the last of the fine particulate settling out.
So what is it... Looking at my "Through the Looking Glass... A Field Guide to Aquatic Plants" I might come up with it being a type of water starwort (Callitriche)?

I found this growing in the local swamp/springs area that is the headwaters of my local creek. In the spring this area is a swamp/pond looking area... this winter is was a standing stream bed... with this stuff growing submerged on the margins.

Got what looks to be the same thing in my 15 I'm setting up for natives. I found it where a stream meets and flows into a large man made lake. Same you described being found at the submerged margins. Been in the tank since Monday, seems to be doing ok so far.

(Would be good to see something for scale - I first thought these were larger leaves until I noticed the sand grains. Was confusing, because the petiole really looks Ludwigia-like, but I thought it was too big for the opposite-leaved species at first.)

It has this awkward desire to grow diagonally sideways, when I want it to grow vertically.
What happens to make some plants of a species red and some green? Like this red ludiwigia palustris: http://www.aquaticpl...ails.php?id=121

I'm curious what causes the color difference among plants of the same species.

I've got Ludwigia repens in my aquarium, but it doesn't look anything like yours. Here's an image: http://gallery.nanfa...repens.png.html

Both of those species can exhbit a good bit of variation with respect to leaf width and length, especially betwen submerged and emersed. Look at the leaves at the base of Michael's plants. In specific, look at their petioles. Then look at the petioles in your photos.
The red is a combination of factors. Some of it is genetics, and some is lighting. Among a number of plant species, some will exhibit more red than others. Of these, some will lose the red under lower light levels. Plants that are commercially available are often redder genetically because they sell better. This is the case for both aquarium plants and garden plants.

I'm thinking Ludwigia palustris. Or possibly L. repens; these are very similar when not in flower.

Here are a couple of pictures proving that...I'm thinking Ludwigia palustris. Or possibly L. repens; these are very similar when not in flower.

1) shiners cannot be used as a comparison scale because they do not hold still
2) I really do have 3-4 inches of soil and sand in this tank
...maybe they also help you identify the plant?

I'd write down Ludwigia palustris in pen.
Gerald, I'll have to tell Mr. Handsome what you said about safe bets...
