Spring is here early, and I decided to collect a few plants at the river and start a new tank. I tried my hand at Samolus Valerandis in my 55, but it didn't work out well. I put together a 6 gallon setup with a brighter light and a tiny pressurized CO2 setup to try again. When I went to get more Samolus, I found a variety of plants and grabbed a little of everything. Any help identifying these would be much appreciated.

This is everything I collected. Four plants besides the Samolus. Everything was submerged when I found it, but water levels change there all the time and any of this stuff may be primarily emergent.



#1 Hairgrass type thing. Really hope this does well!



#2 This one puts down a significant taproot. Larger examples were about a foot tall



#3 Small circular 'pads' in the center of the photo. Grows from a rhizome in the cracks of the rocks. Very pretty stuff



#4 Rear center, grows from a large vinelike rhizome and colonies can get very large. Mostly emergent growths. Red coloration in the veins of the leaves.




Thanks!

I tried doing the same with some of the local plants here in California, but they didn't do well. I hope you succeed the second time around.

Thanks! Not sure if this will work or not. Compared to last time, I have more light, better substrate, and CO2. At least the lizard is getting a kick out of it.

Not sure on your ID, but I'll take a stab at a response just for kicks:

The grass looks like a grass...too bad there's no seed head on it, but I don't think it'll be too happy for long unless it's Texas wildrice, in which case it's illegal...keep us posted...or not...

Number 2 reminds me of a brassica, but I'm really not sure where these were collected (soil type, pH, site of short versus long duration inundation...et cetera).

3 is likely a Hydro. and it may just take time.

Number 4 reminds me of emmersed Ammania sp. growth. You might give that genus a try and see where it leads you.

Thanks for the reply!

The grass probably isn't wildrice. When I looked it up, that one is pretty specific to one stretch of the San Marcos river. This was collected in the upper Gaudalupe which is an hour's drive distant. I'll just have to see what happens. Good chance it may just be grass.

Brassica is a definate maybe. I'm unsure about the soil type, but the river is hard and alkaline. It's fed by a limestone aquifer. Temps this time of year are lower 70's. Water levels can vary considerably with rain.

Couldn't find pictures of a hydro. What's the full name?

As for number 4, most of the ammania pictures I saw looked like a more upright plant. Of course, maybe that's just what it looks like when it isn't being beat to death with water.

I think most of these had no intentions of growing underwater forever. I'm hoping the CO2, and fertilizer might make up for that but only time will tell.

I agree that the grass is probably just grass, not an aquatic plant.

Hydrocotyle sp. is what you're looking for... hard to tell them apart w/o a flower, but H. umbellata is very common down south AFAIK.

Thanks!

I got a chance to run by the house, and I take back what I said about #4 not being upright. It was bent over growing in tangles in the current, but after a couple of days in the tank it's perked up and spreading its leaves. Most of the references to ammania are asian plants. Do any originate here, or is it likely an invader?

I found H. umbellata, and that's it I think. Apparently if it gets too big the trimmings are tasty on salad.

I pulled the grass out and stuck a few more of #4 (ammania?) in it's place.

#4 looks like a Veronica. Maybe. Tough to tell from the photo. Not an Ammannia though.

I wouldn't say it's definitively H. umbellata unless you have a flower to examine - there are several Hydrocotyle species native to the southern U.S. that all look more or less alike. USDA recognizes H. bonariensis, H. prolifera, H. umbellata, and H. verticillata as native to TX, all of which have nearly identical foliage. Your plant could be any of those. (H. ranunculoides is also native, but has distinct foliage).

Can't say I've ever tried Hydrocotyle on a salad, but a number of aquatic plants are in fact edible. It's just that they're more valuable to us as decor than dinner. The invasive watercress in my yard, however, that's going in a bowl with some ranch dressing.

I would tend to agree with Cavan on the 4th one, it does look a lot like a Veronica species...

Veronica led me to Water Speedwell (Veronica anagallis-aquatica L). I think that's #4, thanks! I guess you can eat that one too. The best pictures I found were linked to a "food for free" website, lol



That just leaves this guy.
