I found alot of this plant while hunting for some natives fish for an office picotope. Other plants found with it were Proserpinaca palustris and various Ludwigia spp. Any one know what this is?

I actually do know what it is. If I tell you, will you send me some?

I didn't save your address. PM it to me and 4 rooted stems are yours (about 3" long) .

Sweet. Let me know if you'd like anything else.

It appears to be Gratiola ramosa.

By any chance, is this the same species or something related?

I don't think it's the same species, but I'm not sure of that. An old synonym of G. ramosa is G. quadridentata, and when I looked through a big pile of specimens, nearly all had 4 teeth per leaf. The plant in that photo appears to have more teeth and looks more robust and larger. But then again, I'm not sure what else it could be. It sure could be related. In any case, I'd love to obtain some. I'll see if Paul remembers where he saw that. Then, perhaps, I can grow it emersed and flower it, etc.

Thank You for the informations, Cavan! It would be fine if some of these Gratiolas turn out to be suitable for tanks.
Here in Germany the "Gottesgnadenkraut" (Gratiola officinalis) occurs in wet places, but normally not in water.

Gratiola virginiana does quite well.

I think this may actually be G. brevifolia, which is apparently quite similar and has been recorded in your area. I'll do more digging when I have time and put some in emersed culture as soon as possible so we can get a concrete ID instead of just conjecturing.

Great. I kept 2 stems at my office in a shallow tank ( 8" ). I'll let them pop out of the water here as well as see if they bloom (they get alot of sunlight from the window).

I'll pay a visit to the collection area as well and see if I can re-find them occasionally to see any growth changes.
