Need ID Please

I went and bought a plant at the LFS yesterday and came home not knowing what I bought. Can anyone ID this plant? It's about 8 inches high, single stem, and the leaves are green with pink veins. Some of the smaller leaves are actually all pink.

The pics are not very good quality and I apologize for that - I have not figured out how to take good pictures of a fish tank yet, even with a DSLR.

It looks a little like Alternanthera reineckii (your description matches my book's description). The LFS didn't have a name for it??

They didn't have a name for it and silly me got so excited about buying stuff for the tank that I forgot to ask the question... :-( so I end up having to do research so I know what I have in my tank... sort of a backwards way of going about it. Especially since I went out to get Egeria densa... and came back with "unknown pink plant"!

I'm not too sure about the A. reineckii there, they're more solid in color w/out showing any veins on the leaf if you compare various forms of this with his pictures....Googel pictures and see if you find it fitting your plant.
I thought its Rotala Macranda, thou his is fairly green rather then more red within, but that can be influenced with lights/ picture quality etc

Rotala macrandra occurs to me as well, and the red colour would be much more intense if it had been under strong light and given iron fertilizer.

On another suggestion, the distinctive veining in the leaves suggest Hygrophila polysperma, which Hiscock says can be reddish-brown in colour, which is what the photos here suggest to me. The leaf shape and veins certainly resembles this plant.

Thanks for catching it B - I was wrong, my bet ...

Look here, would say that looks 100% llike your Hygrophila polysperma

OK so now I'm confused!!! I thought I already had Hygrophilia Polysperma in my tank... but the picture Angel posted looks exactly like the plant I bought... so what's the other plant I have then???

Byron 12-08-2009 12:35 PM

I don't think the last photos (the green-leaf stem plant) show H. polysperma; the leaf veins are not pronounced enough for this species.

These photos are looking familiar, was there an earlier thread? Seems to me it could be Heteranthera zosterifolia (Brazilian Stargrass) which has long narrow leaves with one mid-vein. Try searching photos of this species and see if any match.

The tricky thing about naming plant species is that some species can be quite variable in leaf shape, colour and growth habits due to varying light, fertilization and water parameters. And, some nurseries do not correctly name plants, or use common names which is all but meaningless.

Huh... a search on H. polysperma returns images of both the plants I pictured in this thread... yet they are extremely different in shape and colour. This is just weird. On top of that I also have some H.difformis in my tank so it appears that this is in fact a Hygrophilia tank if there ever was one!!!

Thanks all!

It could well, be and the 2nd picture set you have here does look like Hygrophilia family as well. There's SO MANYYYY Hygrophilia's its unreal, they're kinda like Valli's with a thousand different variety's. Just put 'hygrophila' into googel picture search and you'll wind up with a TON results lol
