can you ID these two plants?

[tomfromstlouis]

The first is the stem plant in the lower center of this photo that also pokes up on the left from behind the rock. The stem easily fractures into shorter pieces but stays put and grows well with CO2 and EI dosing.



This second has a poor photo, sorry. It has a single stem and multi-lobed leaves similar to H. difformis in look. It is NOT wisteria though; the leaves are broader and they all come from the central stem. I am asking about the blurred plant beneath the endler and behind the Cyperus helferi leaf.

I know the first picture is guppy grass. Not sure about the second one

Bottom looks like a ceratopteris species.

Looks like H. difformis to me.

Hi tomfromstlouis,

The first one looks like Naja species (guppy grass)

The second on looks like Ceratopteris cornuta (the leaves seem to be coming from a crown and not a stem)

Ahhhh yes....much better eye than I to see that from the pic.

[tomfromstlouis]

Thank you all for the help.

I am doubting your ID for the second plant with the terrible picture because it does indeed have leaves coming from one single stem. Perhaps you can see the stem in this picture:



If you look just above the rock you can see the single green stem. This plant is doing well but does not grow as fast as my hygrophila varieties.

[Jeffww]

Looks like h difformis. From whom did you get this stem?

[acitydweller]

Hygrophilia Angustifolia.

I have this plant or something that looks similar to it

[Jeffww]

He's talking about the pinnate plant in the back.

[tomfromstlouis]

Right Jeff, it is not the hygro we are talking about. I do not remember who gave me the plant but I remember that it hitchhiked in with something I requested. It was just a small piece that I stuck into the substrate it has steadily grown, but not nearly as fast as H. difformis..

It is NOT H. difformis - a plant I have and know well - the primary difference being the way the leaves radiate from the stem. Difformis has leaves that radiate alternately from the stem; these have a PAIR of leaves that come from the stem on opposite sides of the stem every inch or less. One pair radiates east and west, an inch later another pair comes out north and south, etc. The leaves seem a bit broader too, not as needley as difformis.

If needed I will pull it out and provide a better photo.

I think it is too.

Nope, it has opposite leaves, just like all of them.

Opposite and decussate, just as it should be.

[tomfromstlouis]

Is it possible that what I have elsewhere and have always thought of as H. difformis is water sprite? Yes, it is quite possible that I am in error, although memory tells me I bought my original piece of it from a reputable vendor as H. difformis. Then again my memory could be wrong too.
